Alex Langer, Chief Executive Officer, commented, “Q2 was a very productive quarter for Sierra Madre with $8.23 million in net revenues and $1.58 million in gross profit from La Guitarra, as we made significant progress on the expansion, continued the ramp up of the Coloso and Nazareno mines and added equipment and staff to support increased production. During the search for the required mill for Phase I, the Company located and purchased a larger-than-planned mill, with the expectation that it would meet the milling requirements for both phases of the expansion. While the additional foundation and electrical work for the larger mill, along with certain shipping delays for other components of the Phase I expansion extended the completion of Phase I by several weeks, we continue to expect Phase II commissioning prior to the end of Q3 2027. Throughput levels have reached up to 672 tonnes per day so far in August. In June, we also closed the acquisition of a second substantially production-ready asset, the Del Toro silver mine in Zacatecas State, building on our Mexico production-focused platform. We closed out the quarter with US$25 million in working capital and near-term catalysts, including completion of the Phase I expansion and the commencement of East District drilling at La Guitarra.”

Q2 2026 Highlights 

• Revenues: Silver revenues for the quarter totalled $5.0 million ($75.65 per ounce) and gold revenues totalled $4.3 million ($4,529 per ounce).

Operational Details

• Production: Ahead of the Phase I and II expansion plans, Sierra Madre selected a contractor to ramp up production from the higher-grade Coloso and Nazareno mines; contractor operations started mid-June. Sierra Madre miners and equipment are now focused on accelerating production at the Guitarra mine.
• Costs: The Q2 2026 cash costs were negatively impacted by the ramp up and development work at Coloso and Nazareno, leading to a significant share of production being sourced from development drives and out-of-resource, lower grade mineralization.  While adding to top-line revenues, increased commodity prices also add to our cash costs through increased royalty payments and taxes.   The strengthening Mexican peso against the US dollar, inflation impacts on inputs, and rising worker pay rates also affected costs.
• Recoveries: Gold and silver recoveries declined as the ongoing development work opened new mining areas and resulted in a blend of feed from three mining centres. Sierra Madre has built a metallurgical lab at the site to optimize the blending protocol.
• Power Generation: In Q2 2026, power outages continued due to weather incidents, increasing costs. Sierra Madre acquired a 1,250-kilowatt (“kW”) back-up diesel generator for Coloso and Nazareno (installation is underway), plus two 1,500-kW back-up diesel generators for the plant. Installation of the two Guitarra generators was completed mid-August 2026 and are expected to be fully operational in September.
• Equipment: The transfer of a narrow-profile Muki jumbo drill to the Guitarra mine is expected to support development and production of narrower and higher-grade veins in the San Raphael area and of the Juliet vein. Following quarter end, the rebuild of a 0.5-yard scoop tram has reduced dilution and mining costs for the Juliet vein.
• Sierra Madre also purchased two haul trucks in April, to replace rental units used in the tailings buttress program and for Coloso haulage, which are expected to lead to cost reductions. Two scoops were also acquired to support increased mining rates with the expansion.  
• Coloso and Nazareno: Mining restarted at the higher-grade Coloso underground mine at the end of Q1 2025 (estimated resource grades at Coloso are significantly higher in both silver and gold compared to the Guitarra mine veins[1]). In September 2025, Sierra Madre also announced the restart of mining at the Nazareno mine.
• At Coloso, dewatering of the lower levels has been accelerated and production from resource blocks below the existing workings is expected to start in the second half of 2026. Nazareno began full production from long-hole stopes on the 180 level in late April 2026.   

Expansion Progress

• As announced on September 8, 2025, the Company has initiated a plan to expand production capacity at Guitarra in a two-phase program with the first phase aimed at increasing the nameplate capacity of the mill from 500 tpd to a range of 750-800 tpd.  The second phase is anticipated to be completed by Q3 2027, with the aim of increasing the capacity to a range of 1,200-1,500 tpd at Guitarra.
• With the larger-than-planned mill purchased for Phase I, additional foundation and electrical work was required – Sierra Madre now anticipates achieving Phase 1 production capacity before the end of Q3 2026. The purchase of this larger mill has moved the completion of this aspect of the Phase II expansion ahead of schedule.
• Since the end of Q2 2026, foundation work has been completed for the ball mill, support equipment, and building enclosure, with an overhead crane installed.
• Modifications to the existing mill and the installation of larger capacity pumps resulted in an increased total mill throughput capacity: daily production is now reaching up to 672 tpd, a 34% increase over the previous level of 500 tpd.  
• Refurbishment of the used ball mill, purchased in December 2025, was completed at the end of Q1 2026, increasing its rated milling capacity to 900 tpd.
• A standard head crusher, purchased in Q4 2025, started full operation in April 2026 (two months ahead of schedule). Together with modifications to the primary crusher, this addition is expected to allow the circuit to surpass the Phase I objective of 750-800 tpd.
• Thickener tank construction was completed in mid-August 2026, with testing of the mechanical and electrical circuits underway – the thickener is expected to be functional by the end of September. Shipping delays pushed back completion from the original late June 2026 estimate.
• The thickener is designed to thicken tailings to ±60% solids, allowing a significant portion of the tailings to be pumped directly to open stopes below the main San Raphael mine level, using existing tailings pumping equipment.   
• Sierra Madre has also chosen to proceed with the construction of the new permitted dry stack tailings storage facility. Site clearing is expected to start in October. Construction of a filter plant and a second thickener will also be needed for the Phase II expansion. 

Outlook 

• Sierra Madre continues to fine tune site mining and milling, ramp up the Coloso and Nazareno mines, and expand staffing ahead of the anticipated Phase I & II expansion production increases. New mining faces continue to be accessed with the additional equipment being introduced to the operation.
• The Company also expects increased production from the recent re-start of operations at Coloso and Nazareno as the mine development proceeds, de-watering continues, and progress is made towards the higher-grade areas.  
• With the first phase of the Guitarra expansion expected to be completed by the end of September, Sierra Madre expects to see higher production starting in Q3 2026, with an accompanying reduction in costs.

Cautionary Note Regarding Production Decisions 

The Company´s decision to place the mine into commercial production, expand a mine, make other production related decisions, or otherwise carry out mining and processing operations, is largely based on internal non-public Company data and reports from previous operations and the results of test mining and processing.   The Company is not basing any production decisions on NI 43-101 compliant reserve estimates, preliminary economic assessments or feasibility studies and, as a result, there is greater risk and uncertainty as to future economic results from the Guitarra Mine Complex, including increased uncertainty of achieving any particular level of recovery of minerals or the cost of such recovery, including increased risks associated with developing a commercially mineable deposit, and a higher technical risk of failure than would be the case if a feasibility study were completed and relied upon to make a production decision.

("TechSer") of Vancouver B.C., by David Thomas, P.Geo. and QP Geology and Cristian Garcia, P.Eng. and QP Mining, titled "La Guitarra Mineral Resource Estimate Guitarra Silver-Gold Project, Temascaltepec, Estado de México, México" with an effective date of October 24, 2023, is available on SEDAR+ and the company´s website at sierramadregoldandsilver.com/presentations/NI-43-101-La-Guitarra-Mineral-Resource-Estimate.pdf

Trading statement for H1 2026 

In terms of paragraph 6.26 of the Listing Requirements of the JSE Limited (JSE), a company listed on the JSE is required to publish a trading statement as soon as it is satisfied that a reasonable degree of certainty exists that the financial results for the current period to be reported on will differ by at least 20% from the financial results for the previous corresponding period.

Accordingly, stakeholders are advised that Sibanye-Stillwater expects HEPS of between 571 SA cents (34.8 US cents) and 631 SA cents (38.4 US cents) for H1 2026, an increase of more than 200% from 190 SA cents (10.3 US cents) for the six months ended 30 June 2025 (H1 2025). EPS are expected to range between 597 SA cents (36.3 US cents) and 658 SA cents (40.1 US cents), improving by more than 560% from a loss per share of 127 SA cents (6.9 US cents) for H1 2025.

The substantial improvement in earnings reflects stable operational delivery, stronger commodity prices and improved margins. Revenue less cost of sales before amortisation and depreciation for H1 2026 is expected to more than double compared with H1 2025, demonstrating the significant earnings leverage across the portfolio.

The year-on-year comparison is impacted by historical Section 45X credits recognised in H1 2025, which reduced cost of sales before amortisation and depreciation in the comparative period. H1 2025 included R5.1 billion (US$285 million) of Section 45X credits, of which approximately R4.4 billion (US$249 million) related to the cumulative recognition of credits for 2023 and 2024. Excluding Section 45X credits from both periods, the underlying improvement in profitability is even more pronounced.

The substantial increases in HEPS and EPS for H1 2026 compared with H1 2025 are primarily attributable to:

• record financial performance from the SA gold operations (including DRDGOLD), with a 35% increase in the average rand gold price received and a 5% increase in gold sold, more than offsetting lower production and higher costs
• a substantial increase in profitability from the SA PGM operations, with a 67% increase in the average rand 4E PGM basket price received and a 12% increase in PGM sales at consistent production levels
• improved underlying profitability from the US PGM operations, supported by a 70% increase in the average US dollar 2E PGM basket price received
• a standout underlying performance from the Recycling operations, supported by improved profitability at the Pennsylvania (PA) site and the inclusion and successful integration of the North Carolina (NC) site since its acquisition on 4 September 2025
• a significant reduction in impairment charges compared with the R9.7 billion recognised in H1 2025
• an increased share of results from equity-accounted investees, reflecting improved profitability at Mimosa due to higher commodity prices

These positive impacts were partially offset by:

• higher royalties and mining and income taxes associated with the increased profitability arising from the stronger commodity prices

The conversion of rand amounts into US dollars is based on average exchange rates of R16.41/US$ for H1 2026 and R18.39/US$ for H1 2025. US dollar information is provided as supplementary information only.

The financial information on which this Trading statement is based has not been reviewed or reported on by Sibanye-Stillwater’s external auditors.

Operational update for H1 2026 

The Group delivered a strong operational and financial performance during H1 2026. Consistent operational delivery and stronger commodity prices translated into significantly higher profitability, improved margins and strong cash generation. Unless otherwise stated, all comparisons are with H1 2025. The operational and financial information set out below is based on unaudited management accounts for the six months ended 30 June 2026 and remains subject to finalisation.

• The SA gold operations achieved record financial performance, with adjusted EBITDA increasing by approximately 85%. A 35% increase in the average gold price received and a 5% increase in gold sold more than offset lower production and higher costs, resulting in substantially improved margins. Production, including DRDGOLD, decreased by 2% to 9,134kg (293,665oz). Planned production rebasing at Kloof and operational challenges at Beatrix were partly offset by a 13% increase in surface production, including a 10% increase at DRDGOLD to 2,502kg (80,441oz). All-in sustaining costs (AISC) increased by 14% to R1,638,089/kg (US$3,105/oz), reflecting inflation, higher royalties, increased pumping costs at Driefontein, costs to restore operational flexibility at Beatrix and higher third-party material purchase costs at Cooke. Surface production accounted for 36% of total gold produced in H1 2026
• Adjusted EBITDA from the SA PGM operations increased by approximately 300%, demonstrating the substantial earnings leverage from consistent production, a 67% increase in the average PGM basket price and a 12% increase in PGM sales. Production of 831,307 4Eoz, including attributable production from Mimosa and third-party purchase of concentrate (PoC), was broadly in line with the prior period. Stable underground production and higher recovery grades partly offset lower surface production and reduced output from Mimosa. AISC at the managed operations, excluding third-party PoC, increased by 10% to R26,252/4Eoz (US$1,600/4Eoz), primarily due to higher royalties associated with the stronger PGM basket price and inflationary input-cost pressures, but remained approximately 1% below the lower end of annual guidance
• The US PGM operations produced 137,930 2Eoz, 2% lower, primarily due to lower grades at East Boulder and labour constraints. A 70% increase in the average PGM basket price supported profitability and materially improved underlying earnings. Reported adjusted EBITDA decreased by 56%, reflecting the non-recurrence of US$139 million of retrospective Section 45X credits relating to 2023 and 2024 that were recognised in H1 2025. AISC increased by 12% to US$1,347/2Eoz (R22,105/2Eoz), mainly reflecting planned increases in ore-reserve development and sustaining capital associated with the transition to mechanised mining, together with lower production, inflation and higher royalties and property taxes. Importantly, AISC remained below the lower end of annual guidance
• The Recycling operations delivered a standout performance, with adjusted EBITDA increasing by approximately 10% despite the non-recurrence of US$109 million of retrospective Section 45X credits relating to 2023 and 2024 that were recognised in H1 2025. Precious metal ounces recycled and sold increased by 142% to 2.79 million ounces. The strong underlying improvement reflects favourable precious metal prices, higher margin feed streams, increased scale, stronger production at the Pennsylvania site, feed-mix optimisation and the successful integration of the North Carolina site, with operational and commercial synergies being realised across the integrated platform
• The Century zinc retreatment operation produced 45kt of payable zinc, compared with 51kt in H1 2025, due to lower grades, adverse weather conditions and scheduled maintenance. AISC increased by 23% to US$2,162/tZn (R35,477/tZn), primarily reflecting lower production volumes and inflationary cost pressures. A higher equivalent zinc concentrate price more than offset lower production and higher unit costs, with adjusted EBITDA increasing by approximately 50%. Century remained profitable and cash generative as the current tailings retreatment operation approaches the end of its operating life
• At the Keliber lithium project, development progressed from construction to commissioning. Mining commenced at the Syväjärvi open pit, with 217.5kt of ore extracted, and hot commissioning of the concentrator began during the period. Continuous operating runs of up to 142 hours have been achieved to date, marking tangible progress towards stable mining and concentrator operations ahead of the potential refinery start-up

Farhad Abasov, Millennial’s Chair, commented “Millennial is excited to announce another highly successful drill result at the Banio Potash Project. Results of this drillhole are significant in many ways: 

1) Drillhole BA-006 was the first hole drilled near the newly acquired permit area closer to the coast, southwest of the previous drillholes. 

2) The drillhole has once again confirmed a significant section of interbedded carnallitite and halite including numerous thick carnallitite potash seams totalling approximately 80m of cumulative potash mineralization. 

3) This new drillhole significantly expands the known potash footprint to the southwest of the current Mineral Resource Estimate (“MRE”) area. 

4) This is a strategic area for the Company as it is closer to the coast and closer to the planned deep-water port site. 

5) It is important to note that this drillhole intersected Cycles IX and X which had not been previously seen at the project suggesting potential additional  potash seams to the west. 

6) The mineralization is open at depth which indicates we have even more resource expansion potential. We look forward to completing the detailed logging and sampling of these potash horizons and receiving their analytical results. Once all drill data has been interpreted and compiled, an updated MRE will be completed to form a key foundation for the ongoing Definitive Feasibility Study (“DFS”).  The DFS  remains on track for completion by the end of 2026.”

Drillhole BA-006 is collared approximately 4km west of drillhole BA-001 and was designed to test the westward extension of potash mineralization encountered in drillholes BA-001, and the southward extension from BA-002 (See Figure 1).  Preliminary logging of BA-006 indicates that approximately 6 evaporite cycles (Cycles V to X) have been intersected with potash mineralization intersected in each cycle.  It is important to note that BA-006 intersected Cycles IX and X which had not previously been encountered at the project which suggests the thickness of potash mineralization may be increasing to the west.  It is also important that the termination of BA-006 in Cycle V in potash mineralization was due to reaching the depth capabilities of the drill rig and the mineralization remains open at depth as Cycles IV and III have been encountered in BA-002 and BA-001.  

Review of the drill core from BA-006 shows prominent horizontal bedding planes dominated by interbedded halite and carnallite (see Photos 1 and 2 below).  An estimate of the cumulative thickness of the main carnallitite seams from the preliminary logging totals approximately 80m.  Detailed core logging and final interpretation of evaporite cycle and seam identification, as well as downhole geophysical logging, are ongoing. Core preparation and sampling will be completed over the next several weeks and samples submitted to the Saskatchewan Research Council for analyses. 

Figure 1: Location of BA-006 and planned drillholes with the 2025 MRE outline.

The objectives of the Phase 2 program were to evaluate the presence of potash-rich horizons at depth and laterally and to provide geological data on the continuity and characteristics of the potash mineralization beyond the current MRE completed in 2025. Identification of additional potash horizons outlined in BA-006 has extended the known potash mineralization southwest and could potentially add tonnage to the project’s calculated resources which are currently comprised of a Measured MRE of 648.2M tonnes grading 15.7% KCl, an Indicated MRE of 1.8B tonnes grading 15.6% KCl, and an Inferred MRE of 3.56B tonnes grading 15.6% KCl (see press releases dated Dec. 29, 2025 and November 17, 2025). The geological data from BA-006 will be included in an updated MRE planned for completion by the end of 2026 as part of completion of the Definitive Feasibility Study mentioned above.

Halifax, NS – GoGold Resources Inc. (TSX: GGD) (OTCQX: GLGDF) (“GoGold”, “the Company”) - https://www.commodity-tv.com/play/gogold-silver-and-gold-ceo-on-the-start-of-construction-of-the-next-primary-silver-mine-in-mexico/ - is pleased to announce the formal commencement of site construction at Los Ricos South in Jalisco, Mexico.  This milestone follows the completion of a feasibility study in 2025 and the granting of the project permit from the Mexican Government in June of this year. This rapid progress was driven in part by the Company’s decision to initiate the detailed engineering and plant design phase in 2025. First silver and gold pour is scheduled for June 2028.

“We are fully financed with a robust cash position of US$284 million, strong cash flow from our operation at Parral, and zero debt as we begin construction at Los Ricos South,” said Brad Langille, President and CEO. “The decision to advance detailed engineering early has allowed us to get a meaningful head start on long-lead time equipment, which we expect will support an effective execution of the build and keep us on track for first gold pour in June 2028.”

The Company provides the following update on construction and engineering activities: 

1. Underground mining contractor has been selected. Portal construction is scheduled for Q4 2026, with initial mine development to begin in January 2027.
2. Additional geotechnical drilling is currently underway to define exact portal locations and overall underground conditions, which will aid in further optimization of the underground mine plan, with specialist support provided by WSP Geotechnical Engineering.
3. Detailed plant design by M3 and DENM Engineering is approximately 85% complete.
4. RMS (Responsible Mining Solutions) is advancing the detailed design of the paste backfill plant.
5. Orders for all critical long-lead time equipment have been placed, including the SAG mill, tailings filter, crusher, electrical switchgear, Merrill-Crowe plant, conveyors, slurry pumps, hydrocyclones, feeders and screens.
6. The EPCM contractor (M3) is now on site for the construction phase. GoGold has also appointed a construction manager who is currently at site.
7. The earthworks contractor has been mobilized to site, work has commenced at the plant site.
8. As part of its environmental mitigation program, GoGold has launched a regional mitigation program that includes the planting of 20,000 trees to support local reforestation.

All drill holes reported in this release targeted areas currently classified as inferred mineral resources, with results continuing to demonstrate strong continuity of gold mineralization throughout the deposit, which support the Company's ongoing resource conversion objectives.

Significant drill highlights include:

• Hole 26EC-125 intersected 14.41 grams per tonne (g/t) gold over 3.92 m and 7.74 g/t gold over 1.96 m (Figure 2); the most significant result from the third batch of assays;
• Hole 26EC-118 intersected 4.49 g/t gold over 2.94 m and 7.74 g/t gold over 1.96 m, with hole 26EC-129 returning 2.07 g/t gold over 4.94 m and 10.35 g/t gold over 0.99 m (Figure 3); holes 26EC-118 and 26EC-129 were completed within the same mineralized zone, located approximately 250 m and 190 m up-dip, respectively, from hole 26EC-115;
• Hole 26EC-115 intersected 2.88 g/t gold over 8.00 m and 4.19 g/t gold over 4.00 m; these are final results that complete initial results previously reported (see news release dated July 13, 2026); and
• Hole 26EC-120 intersected 5.07 g/t gold over 6.00 m, including 10.20 g/t gold over 1.00 m (Figure 4).
• 15,047 m (or 35 holes) for the Phase 2 Eau Claire program has been drilled.

"These latest results continue to confirm the continuity and quality of the mineralization as we work to convert inferred mineral resources into higher-confidence mineral resource categories," commented Tim Clark, CEO of Fury. "The consistency of mineralization across multiple zones, combined with several high-grade intercepts, further strengthens our confidence in the Eau Claire deposit as we move towards pre-feasibility in 2027." 

Table 1: Recent Drill Highlights 

 Phase 2 drilling is aimed at converting inferred mineral resources into higher-confidence mineral resources categories and expanding the indicated mineral resource. To date, 35 drill holes totalling approximately 15,047 metres have been completed, of which five holes were abandoned. Assay results are currently available for 22 holes totalling 11,423 metres.

Sampling and Assaying Disclosure

Analytical samples for the Drill Program were taken by sawing HQ diameter core into equal halves on site with one half sent to ALS Chemex in Val D’or, Quebec, Canada for preparation and analysis. All samples were assayed using a 50 g nominal weight fire with assay atomic absorption finish (Au-AA24) and multi-element four acid digest ICP-AES/ICP-MS method (ME-MS61). Where Au-AA24 results were greater than 10 ppm by Au-AA24 were re-assayed with 50 g nominal weight fire assay with gravimetric finish (Au-GRA22). QA/QC programs using internal standard samples and blanks, field and lab duplicates, and lab standards and blanks indicate good overall accuracy and precision.

Forward-Looking Statements and Additional Cautionary Language

This news release includes certain statements that may be deemed to be “forward-looking statements” within the meaning of applicable securities laws, which statements relate to the future exploration operations of the Company and may include other statements that are not historical facts. Specific forward-looking statements contained in this news release includes information relating to the Company’s ongoing exploration program at the Eau Claire project.

Although the Company believes that the assumptions and expectations reflected in those forward-looking statements were reasonable at the time such statements were made, there can be no certainty that such assumptions and expectations will prove to be materially correct. Mineral exploration is a high-risk enterprise.

Readers should refer to the risks discussed in the Company’s Annual Information Form and MD&A for the year ended December 31, 2025 and subsequent continuous disclosure filings with the Canadian Securities Administrators available at www.sedarplus.ca and the Company’s Annual Report available at www.sec.gov. Readers should not place heavy reliance on forward-looking information, which is inherently uncertain.

Michael Hudson, President & CEO states: “Of the five mineralized bodies discovered at Sunday Creek, Rising Sun is so far the highest grade. These holes show Rising Sun continues to deliver very high grades into previously untested areas at depth where we traditionally see Victoria epizonal deposits shine. SDDSC230 has delivered one of the top intersections drilled at Sunday Creek: 0.3 m @ 1,466.4 g/t gold, including an individual assay of 0.1 m @ 4,500 g/t gold, from the deepest west-to-east drilling completed beneath Rising Sun to date. That single assay is the fourth highest returned at Sunday Creek and the composite intersection ranks twelfth drilled on the project. That hole is not a one sample story. SDDSC230 and its wedge intersected seven vein sets and stepped out 100 m to 120 m on the RS50, RS60 and RS18 vein sets, while SDDSC231, our deepest west-to-east step-out yet, tied in beside a control hole and confirmed grade continuity a further 150 m out. SDDSC231 returned 0.4 m @ 82.1 g/t gold from 823.3 m and 0.4 m @ 24.3 g/t gold from 1,031.7 m, the deepest mineralization we have intersected at Rising Sun, and the wedge SDDSC230W1 returned 0.4 m @ 88.6 g/t gold from 842.8 m. What also stands out is not only the headline number, it is the consistency behind it. This intersection sits 166 m down-dip of previously reported SDDSC144, which returned 3.6 m @ 118.0 g/t AuEq. 

“Together holes reported here tested approximately 200 m of lateral extent and approximately 300 vertical metres of largely untested ground in Rising Sun at depth, returning three composite intersections above 100 g/t gold, four between 50 g/t and 100 g/t gold and eight individual gold assays above 50 g/t, and intersecting vein sets that sit outside our current Exploration Target. Even SDDSC205, which tracked the footwall of the system rather than drilling through it, returned 0.5 m @ 60.4 g/t gold from 852.4 m including 0.2 m @ 175.0 g/t gold, and we have a wedge planned to test the full width at that depth. 

 “The grades are high, the step-outs are large, and the system is becoming more predictable the deeper we drill it. With eleven rigs turning, results pending from 76 holes and our 200,000 m program running through to Q1 2027, Rising Sun continues to prove and grow in scale with every set of results.”

Drill Hole Discussion

Five drill holes are reported here from the Rising Sun prospect (SDDSC201, SDDSC205, SDDSC230, SDDSC230W1 and SDDSC231), comprising the deepest west-to-east drilling completed beneath Rising Sun to date (Figures 1 to 6). Significant high grades were returned expanding Rising Sun to depth with three (3) composite intersections exceeding 100 g/t Au, four (4) composite intersections between 50 g/t and 100 g/t Au added to project totals and eight (8) individual Au assays greater than 50 g/t Au, one of which exceeded 1,000 g/t Au and represents the 4^th best individual Au intercept on the project to date. The 0.3 m @ 1,466.7 g/t AuEq composite in SDDSC230 also ranks as the 12th best composite intersection returned at Sunday Creek to date. Collectively these holes tested approximately 280 m of down hole length through the Rising Sun vein array, representing approximately 200 m of lateral extent and approximately 300 vertical metres, with grade tenor continuing to improve with depth.

SDDSC201

SDDSC201 was drilled as a shallow control and delineation hole, positioned opportunistically to infill the RS30 vein set up-dip. The hole deviated off target and returned a low-grade result, clipping the periphery of the RS30/RS10 vein set. It did not reduce the known strike extent of that vein. Mineralization was returned outside the modelled altered sediment package while remaining within the pyrite halo, indicating that grade at Rising Sun is not confined to the modelled dyke and altered sediment envelope in this position.

Selected composite highlights include:

• 0.8 m @ 2.6 g/t AuEq (2.6 g/t Au, 0.0% Sb) from 274.0 m

SDDSC205

SDDSC205 intersected four vein sets on the footwall of the system, rather than drilling fully through it, delivering a useful extension into that part of the system. A wedge is planned from SDDSC205 to correct back into the target position and test the full width of the system at this depth.

Selected composite highlights include:

• 0.5 m @ 60.4 g/t AuEq (60.4 g/t Au, 0.0% Sb) from 852.4 m, including;
• 0.17 m @ 175.0 g/t AuEq (175.0 g/t Au, 0.0% Sb) from 852.8 m
• 3.9 m @ 2.6 g/t AuEq (2.5 g/t Au, 0.0% Sb) from 1013.7 m, including;
• 1.1 m @ 5.5 g/t AuEq (5.4 g/t Au, 0.0% Sb) from 1013.7 m
• 4.1 m @ 1.3 g/t AuEq (1.2 g/t Au, 0.1% Sb) from 1021.5 m

SDDSC230 & SDDSC230W1
 SDDSC230 returned a headline composite of 0.3 m @ 1,466.7 g/t AuEq (1,466.4 g/t Au, 0.1% Sb) from 886.7 m, which includes an individual assay of 4,500 g/t Au. This intersection at 886.74 m represents a 166 m extension down-dip to the high-grade intercept in SDDSC144: 3.6 m @ 118.0 g/t AuEq (114.6 g/t Au, 1.4% Sb) from 748.8 m, (refer to ASX announcement dated 18 December 2024), confirming the continuity of the RS19 vein set 166 m up-dip, an unusually consistent result at this tenor and a strong indicator of grade continuity and predictability down-plunge. The SDDSC230 composite ranks as the 12^th best composite intersection returned at Sunday Creek to date (Figures 1 to 4).

Together, SDDSC230 and its wedge SDDSC230W1 intersected seven vein sets and stepped out approximately 100 m to 120 m on the RS50, RS60 and RS18 vein sets and 50 m on RS40 with two vein sets identified outside the current Exploration Target (refer to ASX announcement dated 4 August 2026). 

SDDSC230 returned five individual assays exceeding 50 g/t Au:

4,500.0 g/t Au & 0.33% Sb over 0.10 m from 886.95 m

428.0 g/t Au & 0.15% Sb over 0.10 m from 988.30 m

293.0 g/t Au & 2.20% Sb over 0.39 m from 987.08 m

53.8 g/t Au & 0.01% Sb over 0.67 m from 862.25 m

52.2 g/t Au & 0.01% Sb over 0.63 m from 906.92 m

SDDSC230W1 returned one individual assay exceeding 50 g/t Au:

88.6 g/t Au & 0.01% Sb over 0.44 m from 842.80 m

Selected composite highlights include:

SDDSC230

• 4.3 m @ 9.0 g/t AuEq (9.0 g/t Au, 0.0% Sb) from 858.6 m, including;
• 0.7 m @ 53.8 g/t AuEq (53.8 g/t Au, 0.0% Sb) from 862.3 m
• 0.3 m @ 1,466.7 g/t AuEq (1,466.4 g/t Au, 0.1% Sb) from 886.7 m
• 1.0 m @ 33.0 g/t AuEq (33.0 g/t Au, 0.0% Sb) from 899.1 m
• 0.6 m @ 52.2 g/t AuEq (52.2 g/t Au, 0.0% Sb) from 906.9 m
• 1.3 m @ 120.7 g/t AuEq (119.1 g/t Au, 0.7% Sb) from 987.1 m

Pending Results and Update

Eleven drill rigs are currently operational at Sunday Creek. Results are pending from 76 holes, comprising 54 holes at Sunday Creek and 22 regional holes, all currently being processed and analyzed. These include eleven holes actively being drilled and three abandoned holes (Figures 1-3). The Company's 200,000 m drill program continues through to Q1 2027. 

About Sunday Creek 

The Sunday Creek epizonal-style gold project is located 60 km north of Melbourne within 16,900 hectares (“Ha”) of granted exploration tenements. SXGC is also the freehold landholder of 1,392 Ha that forms the key portion in and around the main drilled area at the Sunday Creek Project.  

Gold and antimony form in a relay of vein sets that cut across a steeply dipping zone of intensely altered rocks (the “host”). These vein sets are like a “Golden Ladder” structure where the main host extends between the side rails deep into the earth, with multiple cross-cutting vein sets that host the gold forming the rungs.  At Apollo, Golden Dyke and Rising Sun these individual ‘rungs’ have been defined over 600 m depth extent from surface to over 1,200 m below surface, are 2.5 m to 3.5 m wide (median widths) (and up to 10 m), and 20 m to 100 m in strike. 

Cumulatively, 278 drill holes for 134,534.25 m have been reported from Sunday Creek since late 2020. This amount includes five holes for 929 m that have been drilled for geotechnical purposes and 23 holes for 3,104.12 m that were abandoned due to deviation or hole conditions. Fourteen drill holes for 2,382.74 m have been reported regionally outside of the main Sunday Creek drill area. A total of 64 historic drill holes for 5,599 m were completed from the late 1960s to 2008. The project now contains a total of ninety-six (96) composite intersections exceeding 100 g/t Au and eighty-three (83) composite intersections between 50 g/t and 100 g/t Au, and one hundred and ten (110) composite intersections exceeding 10% Sb by applying a 1 m (down hole length) @ 5 g/t AuEq lower cut.

Southern Cross Gold’s systematic drill program is strategically targeting these significant vein formations, which are currently drill defined over 1,550 m strike of the host dyke/sediment (“rails of the ladder”) from Christina to Apollo prospects, of which approximately 650 m has been more intensively drill tested (Golden Dyke to Apollo). At least 125 ‘rungs’ have been defined to date, delineated by high-grade intercepts (20 g/t Au to >7,330 g/t Au) along with lower grade edges. Ongoing step-out drilling is aiming to uncover the potential extent of this mineralized system (Figures 1-3). 

Geologically, the project is located within the Melbourne Structural Zone in the Lachlan Fold Belt. The regional host to the Sunday Creek mineralization is an interbedded turbidite sequence of siltstones and minor sandstones metamorphosed to sub-greenschist facies and folded into a set of open north-west trending folds.

Further Information 

Further discussion and analysis of the Sunday Creek project is available through the interactive Vrify 3D animations, presentations and videos all available on the SXGC website.   These data, along with an interview on these results with President & CEO/Managing Director Michael Hudson can be viewed at www.southerncrossgold.com. 

No upper gold grade cut is applied in the averaging and intervals are reported as drill thickness. However, during future Mineral Resource studies, the requirement for assay top cutting will be assessed. The Company notes that due to rounding of assay results to one decimal place, minor variations in calculated composite grades may occur.

Figures 1 to 6 show project location, plan and longitudinal views of drill results reported here and Tables 1 to 3 provide collar and assay data. True thicknesses of the mineralized intervals are reported individually as estimated true widths (“ETW”) where these have been estimated; otherwise, they are interpreted to be approximately 55% to 80% of the sampled thickness. Lower grades were cut at 1.0 g/t AuEq lower cutoff over a maximum width of 2 m with higher grades cut at 5.0 g/t AuEq lower cutoff over a maximum of 1 m width.

Critical Metal Epizonal Gold-Antimony Deposits

Sunday Creek (Figure 6) is an epizonal gold-antimony deposit formed in the late Devonian (like Fosterville, Costerfield and Redcastle), 60 million years later than mesozonal gold systems formed in Victoria (for example Ballarat and Bendigo). Epizonal deposits are a form of orogenic gold deposit classified according to their depth of formation: epizonal (<6 km), mesozonal (6 km to 12 km) and hypozonal (>12 km). 

Epizonal deposits in Victoria often have associated high levels of the critical metal, antimony, and Sunday Creek is no exception. China claims a 56 per cent share of global mined supplies of antimony, according to a 2023 European Union study. Antimony features highly on the critical minerals lists of many countries including Australia, the United States of America, Canada, Japan and the European Union. Australia ranks seventh for antimony production despite all production coming from a single mine at Costerfield in Victoria, located near all SXGC projects. Antimony alloys with lead and tin which results in improved properties for solders, munitions, bearings and batteries. Antimony is a prominent additive for halogen-containing flame retardants. Adequate supplies of antimony are critical to the world's energy transition, and to the high-tech industry, especially the semiconductor and defence sectors where it is a critical additive to primers in munitions. 

Antimony represents approximately 15% to 17% in situ recoverable value of Sunday Creek at an AuEq ratio of 2.39.

About Southern Cross Gold Consolidated Limited (TSX:SXGC) (ASX:SX2) (OTCQX:SXGCF) (Frankfurt: MV3.F) 

Southern Cross Gold Consolidated Ltd. (TSX: SXGC, ASX: SX2, OTCQX: SXGCF), is defining a leading gold-antimony project at the Sunday Creek Gold-Antimony Project, located 60 km north of Melbourne. Sunday Creek is a significant gold and antimony drill discovery in a Tier 1 location, with high-grade drill results including 96 composite intersections exceeding 100 g/t Au from 140.1 km of drilling (including historic drilling). The mineralization follows a "Golden Ladder" structure over 12 km of interpreted strike length, with structures drill tested from surface to 1,200 m depth.

Sunday Creek's strategic value is enhanced by its dual-metal profile. The Company has a critical mineral that the Western world needs. This has gained increased significance following China's export restrictions on antimony, a critical metal for defence and semiconductor applications. Southern Cross’ inclusion in the US Defense Industrial Base Consortium (DIBC) and Australia's AUKUS-related legislative changes position it as a potential key Western antimony supplier. 

Technical fundamentals further strengthen the investment case, with preliminary metallurgical work showing non-refractory mineralization suitable for conventional processing and gold recoveries of 93% to 98% through gravity and flotation. 

With a strong cash position, 1,392 Ha of strategic freehold land ownership, and a large 200 km drill program planned through Q1 2027, SXGC is well-positioned to advance this globally significant gold-antimony discovery in a tier-one jurisdiction, delivering milestone by milestone.

Kenneth Bush, Head of Exploration for SXGC, a Member of the Australian Institute of Geoscientists and a Registered Professional Geologist in the fields of Mining and Exploration (#10315), is the Qualified Person as defined by NI 43-101. He has prepared, reviewed, verified and approved the technical contents of this release. 

Analytical samples are transported to the Bendigo facility of On Site Laboratory Services (“On Site”) which operates under both an ISO 9001 and NATA quality systems. Samples were prepared and analyzed for gold using the fire assay technique (PE01S method; 25 gram charge), followed by measuring the gold in solution with flame AAS equipment. Samples for multi-element analysis (BM011 and over-range methods as required) use aqua regia digestion and ICP-OES analysis. The QA/QC program of Southern Cross Gold consists of the systematic insertion of certified standards of known gold content, blanks within interpreted mineralized rock and quarter core duplicates. In addition, On Site inserts blanks and standards into the analytical process. 

SXGC considers that both gold and antimony that are included in the gold equivalent calculation (“AuEq") have reasonable potential to be recovered and sold at Sunday Creek, given current geochemical understanding, historic production statistics and geologically analogous mining operations. Historically, ore from Sunday Creek was treated onsite or shipped to the Costerfield mine, located 54 km to the northwest of the project, for processing during WW1. The Costerfield mine corridor, now owned by Alkane Resources (previously Mandalay Resources) contains two million ounces of equivalent gold (Mandalay Resources Q3 2021 Results), and in 2020 was the sixth highest-grade global underground mine and a top 5 global producer of antimony. 

SXGC considers that it is appropriate to adopt the same gold equivalent variables as Mandalay Resources Ltd in its 2024 End of Year Mineral Reserves and Resources Press Release, dated February 20, 2025. The gold equivalence formula used by Mandalay Resources was calculated using Costerfield’s 2024 production costs, using a gold price of US$2,500 per ounce, an antimony price of US$19,000 per tonne and 2024 total year metal recoveries of 91% for gold and 92% for antimony, and is as follows: 

𝐴𝑢𝐸𝑞 = 𝐴𝑢 (𝑔/𝑡) + 2.39 × 𝑆𝑏 (%)

Based on the latest Costerfield calculation and given the similar geological styles and historic toll treatment of Sunday Creek mineralization at Costerfield, SXGC considers that a 𝐴𝑢𝐸𝑞 = 𝐴𝑢 (𝑔/𝑡) + 2.39 × 𝑆𝑏 (%) is appropriate to use for the initial exploration targeting of gold-antimony mineralization at Sunday Creek.

VANCOUVER, BC, August 25, 2026 - Banyan Gold Corp. (the "Company" or "Banyan") (TSXV: BYN) (OTCQB: BYAGF) - https://www.commodity-tv.com/play/banyan-gold-strong-drilling-results-at-powerline-and-good-progress-on-the-pea/ - is pleased to announce that the first drillhole at the Seattle Creek zone on the greenfields Nitra Project (“Nitra”), has confirmed a new high-grade gold and silver mineralized system 25 km west of the AurMac Deposit. Only the top 95 metres of the 600-metre hole have been assayed to date. Seattle Creek is located on claims 100% owned by Banyan with no underlying royalties and is the second of eleven exploration targets being drill tested in 2026 on Banyan’s broader 830 sq km AurMac and Nitra land packages in the Mayo Mining District, Yukon (The discovery at the first greenfield target, Roaring Fork and the discovery at Seattle Creek was announced on July 28, 2026, with visible gold and photos of drill core at Seattle Creek.)

Highlights from Seattle Creek Zone at Nitra:

• NT-26-006 – 0.91 g/t Gold and 27.01 g/t Silver over 12.1 m from 41.7 m;
  1. including 4.04 g/t Au over 1.4 m and 3.32 g/t Au over 1.4 m; and within the 4.04 g/t Au interval, 0.5 m returned 5.70 g/t Au and 544 g/t Ag.

*Note: Only assays from the top 95 m of the 600 m NT-26-006 drillhole have been received to date; assays for the lower portion of the hole are pending.

“Initial assays from the Seattle Creek zone have returned high-grade gold and silver mineralization, adding another mineralized zone to our greenfields Nitra project,” stated Tara Christie, President and CEO. “Diamond drillhole NT-26-006 intersected multiple occurrences of visible gold hosted in extensional quartz veins with associated bismuth sulphosalts and arsenopyrite. Together with the other geologic indicators, Seattle Creek has the potential to expand with follow-up drilling. The discovery of additional visible gold identified in drillhole NT-26-002, with assays pending, also supports the potential to extend the Roaring Fork Zone.”

In June 2026, Banyan commenced its greenfields exploration diamond drilling program at Nitra. The program is designed to test 11 regional targets identified through new geophysical surveys, soil geochemical anomalies, placer-mining history and prospecting. More than 7,500 m of drilling is planned to use three helicopter-supported drills to minimize the initial footprint and accelerate target testing. Nitra benefits from an extensive road network established by previous placer mining activities. The objective of the program is to identify potential satellite deposits and additional expressions of Reduced Intrusion-Related Gold Systems ("RIRGs") west of AurMac, where more than 95% of Banyan’s district-scale land package remains untested by drilling.

“The large, annealed shear zone, brecciated quartz veins, and multiphase sulphide mineralization, all spatially associated with high-grade gold mineralization in extensional quartz veins, are encouraging indicators of a potential larger mineralizing system at the Seattle Creek and Roaring Fork zones,” stated Duncan Mackay, Vice President Exploration. “While visible gold can be an encouraging indicator, it does not always correlate with assay grade. We are encouraged that the visible gold at Seattle Creek is associated with high-grade assays and are planning follow-up drilling to test the extent and geometry of the system.” 

Figure 1: Location of the Seattle Creek Zone (Figure 2) in Nitra, approximately 25km west of AurMac and 2.5km north of Roaring Fork Zone.

At Seattle Creek, a combination of soil geochemical anomalies (Gold, Bismuth, Arsenic) and geophysical signatures (resistive anomaly) were used to identify the target. These targeting indicators were combined with proximal placer mining in the creek drainage to locate and prioritize the targets. Mineralization at Seattle Creek is predominantly hosted in large extensional quartz vein hosting bismuth sulphosalts, arsenopyrite, pyrite, and locally sphalerite (Figure 5), and foliation sub-parallel shear veins hosting bismuth-sulphosalts, arsenopyrite, pyrite. Mineralization at Seattle Creek is spatially associated with annealed (cemented) faults with brecciated quartz vein material and wall rock entrained in a pyrite rich ground mass (Figures 7-9). Long lived/reactivated structures are strong indicators for mineralization potential with complex structural regimes and fluid pathways providing opportunities for mineralizing fluids to permeate the country rock and precipitate gold.

Figure 3: Cross Section A-B in Figure 2 – Seattle Creek Zone – Nitra. Numerous visible gold occurrences in potential mineralized zone between 36m and 53m primarily hosted in metasedimentary and metavolcanic rocks. Stratigraphy is dipping moderately (~35-45 degrees) slightly east of south (approx. 165-170 degrees). Extensional veins are dipping moderately (30-50 deg) slightly west of north. Major annealed shear zones at 110-115m (Figure 7 and 8) and 364-367m (Figure 9).  The orientation of annealed shear zones is yet to be confirmed and will require additional drilling.

Figure 5: Potential mineralized intervals from drillhole NT-26-006: Top - 36.2-36.7m – extensional quartz vein bearing visible gold, bismuth sulphosalts, arsenopyrite, and pyrite. Middle – 40.9-41.2m – extensional quartz vein bearing visible gold, bismuth sulphosalts, pyrrhotite, and pyrite. Bottom – 41.9-42.2m – local quartz shear veins and extensional quartz-carbonate veins associated with calc-silicate alteration and pyrrhotite, arsenopyrite, pyrite sulphide replacement of calcareous metasedimentary rocks.

B) 40.9m visible gold spatially associated with pyrrhotite, arsenopyrite, and bismuth sulphosalts. C) and D) 41.0m visible gold spatially associated with pyrrhotite and intergrown with bismuth sulphosalts grains. E) 52.7m visible gold intergrown with arsenopyrite grain. F) 52.7m visible gold in extensional quartz vein.

Figure 7: Zone of intensely sheared/deformed rock in drillhole NT-26-006 (Figure 3). Spatial association with visible gold mineralization from 36-53m in NT-26-006 is a strong indicator of potential for a more widespread mineralizing system at Seattle Creek.

Figure 8: Brecciated quartz shear vein hosting bismuth sulphosalts, arsenopyrite, sphalerite, and pyrite. Late brecciation and mineralization of existing shear veins indicate a long-lived structure which underwent reactivation. Brecciation and mineralized ground mass may indicate high fluid flux through the system; reactivated structures may act as major fluid pathways for concentrating regionally pervasive mineralizing fluids.

Figure 9: Zones of brecciated and annealed rock in drillhole NT-26-006. Healed breccias and associated shear zones may be indicative of long-lived, large structures, which can act as fluid pathways for regional mineralizing systems.

Figure 11: Cross section 7072350N – Drillholes NT-26-001 and -002 (results pending) are shown. Multiple instances of visible gold, including recently identified intervals in NT-26-002 (Figures 12 and 13), are promising indicators of a larger mineralizing system in the Roaring Fork zone. There is a change in rock-type approximately mid-way downhole with folded and highly-strained mixed metavolcanic, metasedimentary, felsic dyke rocks giving way to predominantly metasedimentary rocks dominated by chlorite and moderate grade metamorphic minerals (sillimanite, andalusite, possible retrograde cordierite). Stratigraphy is dipping moderately (~40-45 degrees) slightly east of south (approx. 160-170 degrees). Extensional veins are dipping moderately (20-35 degrees) slightly west of north (340-360). Extensional veins and mineralized shear veins are concentrated in the top 300m of the drillholes (note red traces for extensional veins). 

Figure 12: Quartz extensional vein in NT-26-002, hosting visible gold (Figure 13), pyrite, and bismuth sulphosalts. While visible gold can be an indicator of grade for an interval, due to the variable nature of nuggety gold, presence of visible gold may not always indicate high-grade assay results.

Figure 13: Visible gold occurrences from diamond drillhole NT-26-002 at Roaring Fork Zone:   A) 307.5m visible gold spatially associated with pyrite in quartz shear vein. B) 430.8m visible gold spatially associated with pyrite. C) 432.6m visible gold grain intergrown with pyrite grain, and D) 496.7m visible gold intergrown with pyrite.

Analytical Method and Quality Assurance/Quality Control Measures

The reported work was completed using industry standard procedures, including a quality assurance/quality control (“QA/QC”) program consisting of the insertion of certified reference materials, field duplicates and coarse blanks into the sample stream and utilizing certified independent analytical laboratories for all assays. Additionally, historic QA/QC data and methodology on the AurMac Project were reviewed and will be summarized in the Technical Report‎. The Qualified Persons detected no significant QA/QC issues during review of the data.

A robust system of standards, core duplicates and coarse blanks was implemented in all Banyan’s 2026 drilling programs and was monitored as chemical assay data became available. All control samples were within accuracy and precision thresholds required to meet data quality standards. These control samples amounted to approximately 10% of all samples submitted to analytical laboratories.

All diamond drill core was systematically logged and photographed by Banyan geology personnel.  All core samples (HTW and NTW diameter) were split on-site at Banyan’s core processing facilities. Once split, half samples were placed back in the core boxes with the other half of split samples sealed in poly bags with one part of a three-part sample tag inserted within. Samples were delivered by Banyan personnel or a dedicated expediter to either the Bureau Veritas (“BV”), Whitehorse preparatory laboratory or to AGAT Laboratories Geochemical Mining Division in Calgary (“AGAT”). Samples delivered to BV were prepared and then shipped to Bureau Veritas’s Analytical laboratory in Vancouver, B.C. for pulverization and final chemical analysis.  Samples delivered to AGAT were prepared, pulverized and undergo final chemical analysis in either Calgary or Thunder Bay, Ontario.

Core splits reported in this news release were analysed by either Bureau Veritas of Vancouver, B.C., or AGAT Laboratories in Calgary, Alberta. BV utilized the four-acid digestion ICP-ES 45-element MA-200 or ICP-ES/MS 59-element MA-250 analytical package with FA-450 50-gram Fire Assay with AAS finish for gold on all samples.  Samples returning >10 g/t Au were reanalysed by fire assay with gravimetric finish on a 50g sample (FA-550). High-grade samples with documented visible gold were also analysed using metallic screen fire assay (FS-652). Samples returning >200 g/t Ag (MA250 or MA300) were analysed by multi-acid digestion ICP-ES MA370. If samples returned > 1,500 g/t Ag, they were analysed by fire assay with gravimetric finish on a 50g sample (FA550).  If samples returned > 10,000 g/t Ag, they were analysed by fire assay 2g sample (FA501). Bureau Veritas is an accredited lab following ISO/IEC 17025:2017 SCC File Number 15895. A robust system of standards, ¼ core duplicates and blanks has been implemented in the 2026 exploration drilling program and is monitored as chemical assay data becomes available.

Core splits reported in this news release analysed by AGAT Laboratories of Calgary, Alberta or Thunder Bay, Ontario, utilized the four-acid digestion ICP-OES/ICP-MS 48-element 201-071 analytical package with 201-551 50-gram Fire Assay with AAS finish for gold on all samples.  Samples returning >10 g/t Au were reanalysed by fire assay with gravimetric finish on a 50-gram sample (202-551). High-grade samples with documented visible gold are also analysed using metallic screen fire assay (202-131). Samples returning >100 g/t Ag (201-071) were analysed by multi-acid digestion ICP-OES/ICP-MS 201-470. AGAT is an accredited lab following ISO/IEC 17025:2017 SCC File Number 151266 and 151083. A robust system of standards, ¼ core duplicates and blanks has been implemented in the 2026 exploration drilling program and is monitored as chemical assay data becomes available.

About Banyan 

Banyan’s primary asset, the AurMac Project, is located in the Traditional Territory of the First Nation of Na-Cho Nyäk Dun, in Canada’s Yukon Territory.  The AurMac Project comprises two main deposits, the Airstrip and Powerline Deposits. Mineralization is characteristic of a Reduced Intrusion Related Gold system, hosted in auriferous cross-cutting sheeted quartz veins and replacement style mineralization hosted in skarn horizons. The current Mineral Resource Estimate (“MRE”) for the AurMac Project has an effective date of May 15, 2026 and comprises an Indicated Mineral Resource of 3.639 million ounces of gold (“Au“) (167.3 M tonnes at 0.68 g/t) and an Inferred Mineral Resource of 4.985 Moz of Au (267.2 M tonnes at 0.58 g/t) (See MRE Table below; as defined in the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves incorporated by reference into NI 43‑101). The 303 square kilometres (“sq km”) AurMac Project lies 40 kilometres from Mayo, Yukon. The AurMac Project is transected by the main Yukon highway and benefits from a 69 kVA 3-phase powerline, existing power substation and cell phone coverage.

MRE Table: Pit-constrained Indicated and Inferred Mineral Resources – AurMac Project

Notes to MRE Table:

1. The effective date for the MRE is May 15, 2026, the technical report is available for review on SEDAR+ at www.sedarplus.ca.
2. The Mineral Resource Estimate was prepared by Marc Jutras, P.Eng., M.A.Sc., Principal, Ginto Consulting Inc., who is an independent Qualified Person as defined by NI 43-101.
3. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, changes in global gold markets or other relevant issues.
4. The 2014 CIM Definition Standards were followed for classification of Mineral Resources. The quantity and grade of reported Inferred Mineral Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral Resources as an Indicated Mineral Resource. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
5. Mineral Resources are reported at a cut-off grade of 0.30 g/t gold for all deposits, using a US$/CAN$ exchange rate of 0.73 and constrained within an open pit shell optimized with the Lerchs-Grossman algorithm to constrain the Mineral Resources with the following estimated parameters: gold price of US$3,500/ounce, US$2.75/t mining cost, US$11.50/t processing cost, US$2.00/t G+A, 90% gold recoveries, and 45° pit slopes.
6. The number of tonnes was rounded to the nearest hundred thousand and ounces rounded to the nearest thousand. Any discrepancies in the totals are due to rounding effects.

In addition to the AurMac Project, the Company holds the Hyland Gold Project, located 70 km northeast of Watson Lake, Yukon, along the southeast end of the Tintina Gold Belt (the “Hyland Project”) in the Traditional Territory of the Kaska Nations, closest to the Liard First Nation and Daylu Dena Council. The Hyland Project represents a sediment hosted, structurally controlled, intrusion-related gold deposit, within a large land package (over 125 sq km), accessible by a network of existing gravel access roads. The updated MRE comprises an Indicated Mineral Resource of 337 thousand (“K”) ‎ounces (“oz”) of gold (“Au”) and 2.63 million (“M”) oz of silver (“Ag”) (11.3 M tonnes at 0.93 g/t Au and 7.27 g/t Ag), and an Inferred Mineral Resource of 118 Koz of Au and 0.86 Moz Ag (3.9 M tonnes at 0.95 g/t Au and 6.94 g/t Ag) (as defined in the 2014 CIM Definition ‎Standards for Mineral Resources & Mineral Reserves incorporated by reference into NI 43‑101) effective September 1, 2025 and with technical report filed on Sedar on October 27, 2025.

Banyan also holds the Nitra Gold Project and Seattle-Goodman Creek Project which are grassroots exploration projects located in the Mayo Mining district, adjacent to the AurMac Gold Project. These properties lie in the northern part of the Selwyn Basin and are underlain by metaclastic rocks of the Late Proterozoic Yusezyu Formation of the Hyland Group, similar to lithologies hosting portions of the AurMac Project. Middle Cretaceous Tombstone Plutonic suite intrusions occur along the properties including the Morrison Creek and Minto Creek stocks. The properties are 100% owned by Banyan and cover over 227 sq km. The properties are accessible by road along the Silver Trail Highway, South McQuesten Road and a network of other smaller roads across the properties.

With the ROD now issued, early works construction at South Railroad has begun. Applications for key state permits and water rights have also been submitted.

Jason Simpson, President of Equinox Gold, commented: “Receiving the Record of Decision is a major milestone for the South Railroad project and advances our next phase of growth. The incremental production from South Railroad will be the first meaningful contributor towards our objective of adding 800,000 ounces of annual gold production from our organic development pipeline. Our Board of Directors had previously approved the start of construction, and with the Record of Decision now in hand, South Railroad is positioned for first gold production in 2028. We thank the Bureau of Land Management, Secretary of the Interior Burgum, the U.S. Administration, and the Permitting Council for their support of the Project, including its designation as a FAST-41 covered project, and for their commitment to responsible domestic mineral development.”

South Railroad will be an open-pit heap leach mine. Based on the 2026 feasibility study, the Project is expected to produce an average 130,000 ounces of gold annually over the first five years of operation, and more than 100,000 ounces annually over the initial 10-year mine life. Initial capital costs are estimated at $395 million, including $70-

$80 million reflected in Equinox Gold’s updated 2026 Guidance. The Project is situated within a larger 25,000-hectare land package along Nevada’s prolific Carlin Trend, which provides opportunities for resource growth and new discoveries.

Construction Milestones for Remainder of 2026

Several key construction milestones targeted for completion this year include:

• Workforce ramp-up: As part of operational readiness, hiring and onboarding of site operations team are advancing through the second half of this year.
• Detailed engineering: Engineering is 55.2% complete.
• Ordering and procurement: Major contracts for power generation, process plant equipment, concrete and structural steel have been awarded.
• Construction acceleration: Early works commenced earlier this summer on the north access road outside of the BLM Plan of Operations in coordination with Elko County, Nevada. Earthworks and major civil construction activities have commenced following the receipt of the ROD.
• Equipment: Mining equipment will begin arriving on site at year-end, with initial mining activities scheduled to start in spring 2027.

Cautionary Note Regarding Forward-Looking Statements

This news release includes statements that contain "forward-looking information" within the meaning of the applicable Canadian securities legislation ("forward-looking statements"). All statements, other than statements of historical fact, are forward-looking statements and are based on expectations, estimates and projections as at the date of this news release. Any statement that involves discussion with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions, future events or performance (often, but not always using phrases such as "plans", "expects", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", or "believes" or variations (including negative variations) of such words and phrases, or state that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved) are not statements of historical fact and may be forward-looking statements. In this news release, forward-looking statements relate, among other things, to: the magnitude or quality of mineral deposits; anticipated advancement of mineral properties or programs; future exploration prospects and growth of mineral properties; and the potential expansion or enhancement of mineralization.

These forward-looking statements are based on assumptions management believes to be reasonable at the time such statements are made, including, without limitation, assumptions regarding: the ability of ongoing and future exploration programs to further define, expand or upgrade the ability of ongoing and future exploration programs to further define, expand or upgrade mineralization; and the Company’s ability to execute its plans as currently contemplated. Although the Company believes these assumptions to be reasonable based on information currently available, they may prove to be incorrect. 

Forward-looking statements also involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. Such factors include, among others: risks related to the speculative nature of Newcore’s business; Newcore’s stage of development; Newcore’s financial position; possible variations in mineralization, grade or recovery rates; actual results of current exploration activities; fluctuations in general macroeconomic conditions and securities markets; change in national and local government, legislation, taxation, controls, regulations and political or economic developments; risks and hazards associated with mineral exploration, development and mining (including environmental hazards and unusual or unexpected geological formations); the presence of laws and regulations that may impose restrictions on mining; employee relations; relationships with and claims by local communities; and the speculative nature of mineral exploration and development (including the risks of obtaining necessary licenses, permits and approvals from government authorities). Readers are cautioned that the foregoing list of factors is not exhaustive of the factors that may affect the forward-looking statements.  

Forward-looking statements contained herein are made as of the date of this news release and Newcore disclaims any obligation to update any forward-looking statements, whether as a result of new information, future events or results, except as may be required by applicable securities laws. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.

The Amendment provides the Company with more favourable covenants, reduces the overall cost of capital, and extends the Company's option to settle accrued interest in kind ("PIK") for an additional 12 months. Importantly, following Appian’s review of the results of work completed to date, Appian has confirmed satisfaction of certain key technical conditions precedent to the US$350 million second draw under the Credit Facility, including those related to the Lowhee Zone infill drilling and ore sorting programs, and these conditions have been removed from the Credit Facility pursuant to the Amendment. The second draw remains subject to certain remaining conditions precedent associated with ongoing Project-related construction readiness activities and other customary requirements.

Sean Roosen, Chairman and CEO, commented: "The amended terms of this credit facility provide us with meaningful financial flexibility as we advance the Cariboo Gold Project toward construction readiness. Appian's confirmation that the key technical conditions precedent have been satisfied, including those related to the completed Lowhee infill drilling and ore sorting programs, represents an important validation of the quality of this deposit and the significant de-risking work our team has completed. With the improved economics under the Amendment and US$350 million of additional capital now substantially de-risked, we are well positioned to continue advancing toward our next major development milestones. We thank Appian for its continued partnership and look forward to working together through the next phase of development at Cariboo."

The Amendment provides for a reduction in applicable interest rate margins under the Credit Facility as follows: (i) for the initial draw, 3-month Secured Overnight Financing Rate ("SOFR") plus a margin of 9.00% per annum (reduced from SOFR plus 9.50% per annum), together with the elimination of the 0.10% per annum SOFR adjustment; and (ii) for the second draw and thereafter, SOFR plus a margin of 7.25% per annum (reduced from SOFR plus 7.50% per annum).

All of the existing guarantees, security and other obligations provided for under the Credit Facility remain in full force and effect and have been reaffirmed in connection with the Amendment. Except as expressly amended, all other terms of the Credit Facility remain unchanged. Barkerville paid an amendment fee to Appian in connection with the Amendment.

The description of the Amendment set forth in this news release is a summary only and is qualified in its entirety by the full text of the amended and restated credit agreement dated August 20, 2026 among Barkerville, as borrower, Appian, as lender, TSX Trust Company, as collateral agent, and Appian ODV (Jersey) Ltd., as administrative agent. A copy of the Amendment will be filed on SEDAR+ (www.sedarplus.ca) under the Company's issuer profile.

Tony Makuch, Discovery’s President, CEO and Chairman, commented: “Exploration drilling at Borden continues to generate excellent results. Borden includes an extensive land position in a highlyprospective, under explored, greenstone belt in the Abitibi. Today’s results include further progress with resource conversion and expansion drilling in the Main and East Lower zones, where we continue to produce intersections that as good, or better, than those included the current resource model. In addition, we have been ramping up surface drilling to begin accessing Borden’s larger-scale potential of growth. Early results from surface drilling have been very encouraging, including returning intersections that extend the Main Zone by over half a kilometre down plunge to the northeast from the current inferred resource. These results highlight the prospectivity of the area and are a great start to our plan to build-out the Borden operation. We plan to continue drilling to the northeast to find additional extensions as work to demonstrate that there is much more gold to be discovered on our 1,000 km² land position in the Abitibi near Chapleau.”  

Drilling at the Borden Mine included a total of 22 holes (7,411.6m) from surface and underground to convert and expand resources in the Main Zone and East Lower Zone, near the northeast limit of inferred resources (Figures 1, 2 and 3).  

Link to 3D Visuals: https://vrify.com/decks/23611?auth=a727fee7-ac0e-4d36-8728-7e60aa2614fd 

The Borden Mine is located approximately 190 km southwest of the Dome Mill, near Chapleau and in the south portion of the Borden Lake Greenstone Belt. The Main Zone is an east-west trending structure located along the east - west trending Genesis Deformation Zone (“GDZ”) adjacent to a major contact between felsic gneiss and amphibolite. Work to date has traced the zone for a strike length of over 1.7 km along strike and indicates the zone is closely associated with quartz veining, biotite-garnet alteration and pyrite. The ELZ is a parallel trending, and less explored, structure located approximately 500 m to the west of the Main Zone where recent work indicates potential for significant upside.       

Drilling at the Main Zone included 1 hole (1,344) completed from surface and 14 holes (4,187.6 m) drilled from underground.  

Drilling from underground included was completed from cut outs located in the east portion of the 585exploration drift, situated in the hanging wall of the zone and continued to demonstrate extremely positive results including intercepts of  9.16 gpt over 25.9m including 18.40 gpt over 4.0m and including 21.52gpt over 4.8m, in 585-00275; 12.79 gpt over 7.3m, including 18.45 gpt over 4.4m in hole 585-00142; 6.11 gpt over 3.2m, in hole 585-00130; 7.01 gpt over 10.2m, in 585-00148; 4.75gpt over 19.3m, including 7.90 gpt over 5.0m, in hole 585-00305; and 9.23 gpt over 14.0m, including 13.41 gpt over 8.3m, in hole 585-00306 (Table 1). Holes 585-00142 and 585-00130 were drilled approximately 100 meters down plunge of the current inferred resource and holes 585-00305 and 58500306 were drilled 75 to 100 meters to the east. 

Hole BL26-001119, drilled from surface, targeted 350 meters along strike from the current resource and achieved positive results with an intercept of 6.34 gpt over 8.7m, including 11.04 gpt over 3.7m. 

Drilling at the East Lower Zone included 7 holes (1,880 m) completed from two drill bays located on the 585 level to confirm and evaluate expansion potential near the lower limits of the zone. Significant results include: 6.92 gpt over 12.9m, including 9.16 gpt over 7.3m, in hole 585-00292; 13.33 gpt over 13.2m, including 31.04 gpt over 4.7m, in hole 585-00291; 5.25 gpt over 15.4m, including 10.09 gpt over 5.5m, in hole 585-00298; 10.21 gpt over 3.9m, in hole 585-00294; and 3.59 gpt over 17.4, in hole 585-00290, which are located near the limit of the current inferred resource. The zone remains open to depth.  

Review of the above drill results indicate that both the Main Zone and East Lower Zone are trending close to plan and with grades and widths that are similar to, or better than, the current resource model. These results, along with new intercepts located down plunge and to the northeast continue to demonstrate the excellent potential for further resource growth as drilling continues.  

The program is continuing with four underground drills working to convert and extend resources. Work is also continuing to advance the 585-exploration drift to the northeast to provide new drill platforms for future drilling. Two surface drills are also operating in the area northeast of the Main Zone.

QUALIFIED PERSONS 

Discovery’s exploration programs at Borden are conducted under the supervision of Eric Kallio, P.Geo., Senior Vice President, Exploration, Kara Byrnes, P. Geo, Vice President, Exploration and Geology – Porcupine and Craig Yuill, P.Geo., Exploration Manager. Mr. Kallio, Ms. Byrnes and Mr. Yuill are “qualified persons” for the purpose of National Instrument 43-101, Standards of Disclosure for Mineral Projects, of the Canadian Securities Administrators, and have reviewed and approved the scientific and technical information in this news release. 

Readers are referred to the mineral resource estimate as set out in the Company’s current technical report entitled “Porcupine Complex, Ontario, Canada NI 43-101 Report on Preliminary Assessment” with an effective date of January 13, 2025 (the “Technical Report”), which is available under the Company’s issuer profile on SEDAR+ at www.sedarplus.ca. Statements concerning mineral resource estimates may also be deemed to constitute forward looking information to the extent that they involve estimates of the mineralization that will be encountered if the property is developed. The Technical Report includes the results of a preliminary economic assessment which is preliminary in nature. It includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that the preliminary economic assessment will be realized.  

QA/QC CONTROLS 

The Company follows a quality assurance and control (“QA/QC”) program to ensure that sampling and analysis of all exploration work is conducted in accordance with best practices.

At Borden, samples are logged and sampled in a secure facility in Chapleau, Ontario and under supervision of Qualified Geologists. NQ sized core is predominantly sawn in half with one half of the core prepared for shipment, the other half of core retained for future assay verification. Certified reference material (CRM) standards, coarse blank material and duplicates are inserted every 20 samples. Core samples are picked up by Activation Laboratories and tracked via a chain of custody from site to the certified off-site analytical laboratory for preparation and assaying. 

Discovery utilizes the accredited external lab Activation Laboratories to manage its core analysis. 

ActLabs is certified by the Standards Council of Canada which conforms with ASB-RG Mineral Analysis Laboratory for the Accreditation of Mineral Analysis Testing Laboratories and CAN-P-4E ISO/IEC 17025: General Requirements for the Competence of Testing and Calibration Laboratories.  

Sample preparation includes crushing drill core up to 80% passing 2 mm, riffle splitting 500 grams and pulverizing to 95% passing 105 µm followed by both scheduled and specifically requested silica sand cleaning. Gold Analysis involves Fire Assay – Atomic Absorption technique from a 50-gram pulp sample with grade ranges between 5 to 10,000 ppb. Samples greater than 10,000 ppb are analyzed with a gravimetric finish. Selected high grade samples are also analyzed using the screen metallics procedure. 

ABOUT DISCOVERY 

Discovery Mining Ltd. is a growing precious metals company that is creating value for stakeholders through exposure to gold, silver and other critical minerals. Discovery is advancing plans to more than double annual gold production through investment in the Company’s Porcupine assets, which include multiple operations, attractive growth projects and significant exploration upside in one of the world’s most renowned gold camps in and near Timmins, Ontario. The acquisition of the Kidd Operations in June 2026 further increased Discovery’s land position within the camp, provided valuable infrastructure that will support the Company’s growing gold business, and added critical minerals to the Company’s current production profile. Discovery’s silver exposure comes mainly from the 100%-owned Cordero project, one of the world’s largest undeveloped silver deposits, which is located close to infrastructure in a prolific mining belt in Chihuahua State, Mexico.

2026 Program Highlights

• Uranium mineralization encountered across Rustler: Thirteen of 22 holes drilled in the Rustler target area (drill holes RT26-082 through RT26-104) encountered uranium mineralization at grades of 0.02% eU₃O₈ or higher (Table 1). Notably, hole RT26-085 intersected 3.5 ft grading 0.135% eU₃O₈, including 2 ft grading 0.204% eU₃O₈, confirming the presence of uranium mineralization within the system.
• Two distinct mineralized sandstone units identified at Rustler: Drilling has confirmed uranium mineralization within two separate sandstone units in the lower Wasatch Formation, the principal host formation for uranium deposits in the adjoining Pumpkin Buttes mining district. Uranium mineralization has been encountered in both sands, and gamma ray borehole geophysical log results indicate possible stacked roll fronts in the upper unit. Oxidation states of the two sandstone units indicate that the two mineralized systems are independent of one another, with the redox boundary in the lower sand unit well to the east of the redox boundary in the upper sand, providing multiple prospective trends for ongoing exploration (Figure 2).
• Additional uranium mineralization encountered at Outpost: Seven of 27 holes completed (drill holes LT26-074 through LT26-100) at the Outpost target encountered uranium mineralization grading 0.02% eU₃O₈ or higher (Table 1 and Figure 3).
• Growing geological model guiding ongoing drilling: Combined 2025 and 2026 results at Rustler are providing an increasingly detailed picture of subsurface channel geometry and associated mineralized trends. Radiometric assay results and borehole geophysical data are being incorporated in real time to refine the geological model and guide subsequent drill locations.

Colin Healey, CEO of PUR commented, “We’re seeing good success from our 2026 program at Kaycee, with nearly half of the planned 100,000 feet of drilling now complete. With approximately 430 miles of interpreted roll fronts, we believe we are just beginning to unlock the potential of this large mineralized system. This year’s drilling is focused on systematically testing that potential, identifying the extents of mineralization in the targeted areas and identifying the areas with the greatest opportunity to build pounds. The results at Rustler are particularly encouraging, with mineralization identified in two distinct sandstone units and indications of potentially stacked roll fronts. As we continue drilling, our goal is to advance these mineralized trends and build the geological understanding needed to ultimately define a meaningful uranium resource at Kaycee.”

Table 1. 2026 Kaycee Significant Intercepts

Notes: Drill holes reported here encountered uranium mineralization at or above a cut-off grade of 0.02% eU₃O₈. All grades were calculated from gamma-ray logs measured by Hawkins CBM Logging of Casper, Wyoming, which is independent of the Company. The geophysical results are based on equivalent uranium (eU₃O₈) of the gamma-ray probes which are calibrated at the Department of Energy’s test facility in Casper, Wyoming. Uranium grades cited are calculated from gamma-ray logs, and the cited grades are “equivalent” (“e”) grades of U₃O₈ %. eU₃O₈ is a measure of gamma intensity from a decay product of uranium and is not a direct measurement of uranium. No corrections were made for radiometric disequilibrium. Numerous comparisons of eU₃O₈ and chemical assays of PRB core samples indicate that eU₃O₈ is a reasonable indicator of the actual uranium assay. All drill holes are vertical in orientation and the geologic units hosting the uranium mineralization are generally very flat lying, therefore reported thicknesses represent true thicknesses.

Kaycee Project
 

The Kaycee Project in Wyoming's Powder River Basin (PRB) consists of over 42 square miles of mineral rights over a 36-mile mineralized trend hosting more than 110 miles of identified roll fronts (Figure 4). The Project is believed to be the only project in the PRB where all three known historically productive sandstone formations (Wasatch, Fort Union, and Lance) are mineralized and potentially accessible for ISR extraction. The Project represents the largest grass-roots ISR exploration project in the United States, with upwards of 400,000 ft of drilling completed since 2023.

PUR anchors one of the strongest exploration portfolios in Wyoming, combining its Cyclone Project in the Great Divide Basin with Kaycee to drive one of the largest ongoing drilling programs in the state and significantly expand its presence in both of the state’s major ISR-amenable uranium districts.

VANCOUVER, BC, August 17, 2026 - Banyan Gold Corp. (the "Company" or "Banyan") (TSX-V: BYN) (OTCQB: BYAGF) - https://www.commodity-tv.com/ondemand/companies/profil/banyan-gold-corp/ - is pleased to announce it has intersected very high-grade gold (“Au”) mineralization in the northern portion of the Powerline Deposit (“Powerline”), highlighting the potential to upgrade mineralized domains and expand the high-grade core of the Powerline Deposit, AurMac Project (“AurMac”), Yukon, Canada. Drillhole AX-26-874 intersected 13.03 g/t Au over 14.2 metres, including 142.70 g/t Au over 1.0 metre, extending high-grade mineralization toward the largely undrilled gap between the Powerline and Airstrip Deposits (Figure 1). Much of this area is currently classified as unmineralized in the Mineral Resource model. The results are part of Banyan’s ongoing 2026 drill program at AurMac, focused on resource conversion, expansion and delineation of higher-grade mineralized domains within and adjacent to the current resource envelope.

Highlights from Powerline North:

AX-26-874 - 13.03 g/t Au over 14.2 metres (“m”), (true width 90% - 12.8m)

1. including 18.10 g/t Au over 1.5m,
2. 142.7 g/t Au over 1.0m,
3. and 12.77 g/t Au over 1.2m; and,
4. 0.80 g/t Au over 54.5 m including 6.39 g/t Au over 1.5m.

AX-26-832 – 1.17 g/t Au over 11.2m within 0.57 g/t Au over 26.1m 

1. including high-grade of 7.40 g/t Au over 1.0m

AX-26-840 – 1.86 g/t Au over 13.9m, 

1. including high-grade of 22.30 g/t Au over 1.0m; and,
2. 0.42 g/t Au over 59.0m, including high-grade of 13.90 g/t Au over 0.5m

AX-26-871 – 1.42 g/t Au over 13.5m 

1. including high-grade of 16.03 g/t Au over 0.6m, 4.07 g/t Au over 0.4m and 9.81 g/t Au over 0.3m

“The 13.03 g/t Au over 14.2 metres intersected in AX-26-874 is an exceptional result, while its location is equally important,” stated Tara Christie, President & CEO. “This intercept extends high-grade mineralization into the largely undrilled gap between Powerline and Airstrip, an area currently classified as unmineralized in the resource model. Our 2026 program is designed not only to convert resources, but also to identify these higher-grade domains and demonstrate the potential to increase both contained ounces and the overall grade profile at AurMac.”

The high-grade interval in AX-26-874 is characterized by a high density of extensional quartz veins with bismuth sulphosalts, arsenopyrite and pyrite, together with multiple occurrences of visible gold. The 142.70 g/t Au over 1.0 m interval is associated with a locally brecciated extensional quartz vein containing coarse-grained to semi-massive arsenopyrite (Figure 5).

Figure 1: Plan map of AurMac, Yukon, Canada. Drillholes in this release highlighted in blue (Figure 2). Pending results in green. All other diamond drilling is in black. The gaps between Airstrip and Powerline fall within the conceptual pit boundary but remain largely undrilled except for the two fences of drilling in the centre and eastern end of the area.

Figure 2: Plan map of Powerline North. Drillholes in this release highlight the potential to extend and delineate new high-grade zones in the core of Powerline (Figures 3 and 4). Drillholes AX-26-832, -840, -845, and -850 drill off angle to test continuity of mineralization below the substation infrastructure.

Figure 3: Cross-section 467100mE from Powerline North at AurMac. Mineralized domains are overlaid on the lithologic model. Mineralization remains open up-dip toward the largely undrilled gap between the Airstrip and Powerline Deposits and at depth. The high-grade interval in AX-26-874 (Figure 5) highlights the potential to extend mineralized domains beyond the current resource model and to identify additional mineralization within areas currently estimated at low grade or as unmineralized within the conceptual pit shell. The MRE block model is constrained by mineralized and lithologic domains. Mineral Resource blocks are 10m x 10m x 5m. Only blocks above the 0.30 g/t Au cut-off and within the US$3,500/oz Au conceptual pit shell are included in the MRE.

Lithologic domains at Powerline are dominated by metasedimentary rocks of various compositions, typically mica-chlorite schists with varying calcareous content. Domains shown in this section are: CLSR_4 and 5 – chlorite-sericite schist; CSCH_1 and 3 – calcareous schist; and sch_2 – heterogeneous schist. 

Figure 4: Cross-section 466900mE from Powerline North at AurMac. Mineralized domains are overlaid on the lithologic model. Mineralized domains are open up-dip and at depth, with potential to expand the mineralized envelope at depth. The MRE block model is constrained by mineralized domains and the lithologic domains. Mineral Resource blocks are 10m x 10m x 5m. Only blocks above the 0.30 g/t Au cutoff and within the US$3,500/oz Au conceptual pit shell are included in the MRE.

High density of extensional quartz veins with bismuth-sulphosalts, arsenopyrite, and pyrite found throughout the mineralized interval from 160.0-174.2m, which graded 13.03 g/t Au over 14.2m and hosts several instances of visible gold mineralization (Figure 6). Locally, very high-grade gold intersection of 142.70 g/t Au over 1.0m is associated with locally brecciated quartz extensional vein with coarse-grained to semi-massive arsenopyrite.

Analytical Method and Quality Assurance/Quality Control Measures

The reported work was completed using industry standard procedures, including a quality assurance/quality control (“QA/QC”) program consisting of the insertion of certified reference materials, field duplicates and coarse blanks into the sample stream and utilizing certified independent analytical laboratories for all assays. Additionally, historic QA/QC data and methodology on the AurMac Project were reviewed and are summarized in the Technical Report‎. The Qualified Person detected no significant QA/QC issues during review of the data.

A robust system of standards, core duplicates and coarse blanks was implemented in all Banyan drilling programs and was monitored as chemical assay data became available. All control samples were within accuracy and precision thresholds required to meet data quality standards. These control samples amounted to approximately 10% of all samples submitted to analytical laboratories.

All diamond drill core was systematically logged and photographed by Banyan geology personnel.  All core samples (HTW and NTW diameter) were split on-site at Banyan’s core processing facilities. Once split, half samples were placed back in the core boxes with the other half of split samples sealed in poly bags with one part of a three-part sample tag inserted within. Samples were delivered by Banyan personnel or a dedicated expediter to the Bureau Veritas, Whitehorse preparatory laboratory where samples are prepared and then shipped to Bureau Veritas’s Analytical laboratory in Vancouver, B.C. for pulverization and final chemical analysis.  

Core splits reported in this news release were analysed by Bureau Veritas of Vancouver, B.C., utilizing the four-acid digestion ICP-ES 35-element MA-300 or ICP-ES/MS 59-element MA-250 analytical package with FA-450 50-gram Fire Assay with AAS finish for gold on all samples.  Samples returning >10 g/t Au were reanalysed by fire assay with gravimetric finish on a 50g sample (FA-550). High-grade samples with documented visible gold are also analysed using metallic screen fire assay (FS-652). Samples returning >200 g/t Ag (MA250 or MA300) were analysed by multi-acid digestion ICP-ES MA370. If samples returned > 1,500 g/t Ag, they were analysed by fire assay with gravimetric finish on a 50g sample (FA550).   If samples returned > 10,000 g/t Ag, they were analysed by fire assay 2g sample (FA501). Bureau Veritas is an accredited laboratory following ISO/IEC 17025:2017 SCC File Number 15895. A robust system of standards, ¼ core duplicates and blanks has been implemented in the 2026 exploration drilling program and is monitored as chemical assay data becomes available.

About Banyan 

Banyan’s primary asset, the AurMac Project is located in the Traditional Territory of the First Nation of Na-Cho Nyäk Dun, in Canada’s Yukon Territory.  The AurMac Project comprises two main deposits, the Airstrip and Powerline Deposits. Mineralization is characteristic of a Reduced Intrusion Related Gold system, hosted in auriferous cross-cutting sheeted quartz veins and replacement style mineralization hosted in skarn horizons. The current Mineral Resource Estimate (“MRE”) for the AurMac Project has an effective date of May 15, 2026 and comprises an Indicated Mineral Resource of 3.639 million ounces of gold (“Au“) (167.3 M tonnes at 0.68 g/t) and an Inferred Mineral Resource of 4.985 Moz of Au (267.2 M tonnes at 0.58 g/t) (See MRE Table below; as defined in the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves incorporated by reference into NI 43‑101). The 303 square kilometres (“sq km”) AurMac Project lies 40 kilometres from Mayo, Yukon. The AurMac Project is transected by the main Yukon highway and benefits from a 69 kV 3-phase powerline, existing power substation and cell phone coverage.

MRE Table: Pit-constrained Indicated and Inferred Mineral Resources – AurMac Project

Notes to MRE Table:

1. The effective date for the MRE is May 15, 2026, the technical report is available for review on SEDAR+ at www.sedarplus.ca.
2. The Mineral Resource Estimate was prepared by Marc Jutras, P.Eng., M.A.Sc., Principal, Ginto Consulting Inc., who is an independent Qualified Person as defined by NI 43-101.
3. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, changes in global gold markets or other relevant issues.
4. The 2014 CIM Definition Standards were followed for classification of Mineral Resources. The quantity and grade of reported Inferred Mineral Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral Resources as an Indicated Mineral Resource. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
5. Mineral Resources are reported at a cut-off grade of 0.30 g/t gold for all deposits, using a US$/CAN$ exchange rate of 0.73 and constrained within an open pit shell optimized with the Lerchs-Grossman algorithm to constrain the Mineral Resources with the following estimated parameters: gold price of US$3,500/ounce, US$2.75/t mining cost, US$11.50/t processing cost, US$2.00/t G+A, 90% gold recoveries, and 45° pit slopes.
6. The number of tonnes was rounded to the nearest hundred thousand and ounces rounded to the nearest thousand. Any discrepancies in the totals are due to rounding effects.

In addition to the AurMac Project, the Company holds the Hyland Gold Project, located 70 km northeast of Watson Lake, Yukon, along the southeast end of the Tintina Gold Belt (the “Hyland Project”) in the Traditional Territory of the Kaska Nations, closest to the Liard First Nation and Daylu Dena Council. The Hyland Project represents a sediment hosted, structurally controlled, intrusion-related gold deposit, within a large land package (over 125 sq km), accessible by a network of existing gravel access roads. The Hyland Project MRE comprises an Indicated Mineral Resource of 337 thousand (“K”) ‎ounces (“oz”) of gold (“Au”) and 2.63 million (“M”) oz of silver (“Ag”) (11.3 M tonnes at 0.93 g/t Au and 7.27 g/t Ag), and an Inferred Mineral Resource of 118 Koz of Au and 0.86 Moz Ag (3.9 M tonnes at 0.95 g/t Au and 6.94 g/t Ag) (as defined in the 2014 CIM Definition ‎Standards for Mineral Resources & Mineral Reserves incorporated by reference into NI 43‑101) effective September 1, 2025 and with a technical report filed on Sedar on October 27, 2025.

Banyan also holds the Nitra Gold Project and Seattle-Goodman Creek Project which are grassroots exploration projects located in the Mayo Mining district, adjacent to the AurMac Gold Project. These properties lie in the northern part of the Selwyn Basin and are underlain by metaclastic rocks of the Late Proterozoic Yusezyu Formation of the Hyland Group, similar to lithologies hosting portions of the AurMac Project. Middle Cretaceous Tombstone Plutonic suite intrusions occur along the properties including the Morrison Creek and Minto Creek stocks. The properties are 100% owned by Banyan and cover over 530 sq km. The properties are accessible by road along the Silver Trail Highway, South McQuesten Road and a network of other smaller roads across the properties.

Pre-Construction Activities

The Company continues to advance pre-construction activities, including certain surface infrastructure and underground development.

• Water treatment plant: Upgrades to the Bonanza Ledge water treatment plant are complete. Final commissioning continues, with full operation expected in Q3 2026.
• Underground development: Approximately 2.7 km of underground development has been completed to date. Underground development continues from the existing Cow Portal into the Lowhee Zone and along the main access ramp into the Cow Mountain Zone. Development reached the first access point into the Cow Mountain Zone where a dedicated drill gallery is being advanced to enable infill drilling to support resource conversion, which is expected to commence in Q3 2026 (see Figure 1). Development rates continue to improve as headings advance beyond the Lowhee fault into more favourable ground conditions. Progress through the Lowhee fault zone was below target due to enhanced ground support requirements. At the mine site complex, earthworks have commenced on the second underground access at the Valley Portal. Once established, the Valley Portal will provide a second development front and support critical path primary development access to the Valley and Shaft Zones, which host the majority of the Cariboo Gold deposit's mineral reserves and mineral resources.
• Surface infrastructure: Construction of the waste rock storage facility, the sediment control pond, and other critical infrastructure is progressing. Early works at the mine site complex, which will host the primary processing facility, commenced in Q2 2026 and include tree clearing and geotechnical drilling. Once excavation of the Valley Portal is sufficiently advanced, earthworks and foundation construction for the main water treatment plant are expected to commence in Q3 2026. Installation of the Willow River Bridge, which will provide the Project's primary access once completed, is also expected to begin in Q3 2026.
• Camp upgrade: The site camp upgrade and expansion to 358 rooms is complete and, together with other Company-controlled accommodations, is expected to provide sufficient capacity aligned with peak construction and exploration manpower requirements.
• Project Readiness: Detailed engineering and procurement activities continue across key work streams supporting project readiness. Key areas of focus include process plant design work, site infrastructure and layout optimization, procurement of certain long-lead and major equipment packages, vendor engagement and technical bid evaluations, among others. In parallel, third-party reviews of key engineering, execution and cost inputs are also underway to further de-risk the Project and support a disciplined approach to construction readiness planning.

Infill Drilling Program

An infill drill program was completed as part of the Appian project financing obligations totaling approximately 13,684 metres. An additional 2,995 m of infill and near mine exploration drilling was released as part of ongoing Lowhee Zone underground drilling.

• The Company completed a preliminary internal reconciliation analysis of two localized areas (Zones 1 and 2), comprising an aggregate total of 17,072 metres of infill drilling in 185 diamond drill holes, which illustrated deposit variability broadly consistent with expectations.
• Relative to the existing short-term resource model, Zone 1 indicated approximately 30% more tonnes and 6% more gold ounces, at approximately 18% lower gold grade, while Zone 2 indicated approximately 8% fewer tonnes and 8% more gold ounces, at approximately 16% higher gold grade.^{1 (pg. 10)}

Exploration and Conversion Drilling Programs

A multi-faceted exploration drilling campaign across the Cariboo Gold Project and regional targets is underway. The current and planned infill drilling has the objective of (a) supporting greater definition of the existing measured and indicated mineral resources and (b) upgrading inferred mineral resources to higher confidence categories and, where appropriate, potentially converting such resources into mineral reserves after considering applicable modifying factors. Up to 20 drill rigs are expected to be active at times throughout 2026 and beyond, as the various programs overlap and advance, representing up to approximately 160,000 metres of planned drilling across all targets. Thirteen drill rigs are currently operating across all programs, including three drills active underground.

• A total of ten drill rigs are currently operating on four surface exploration programs, including three surface drill rigs targeting potential mineralization within and below the current extent of the Cariboo Gold deposit to depths of up to 1,000 metres. To date, approximately 19,215 metres of drilling have been completed, with assay results for 8,971 metres released. Assay results for the remaining drill holes are pending. Underground development of a dedicated drill gallery is progressing in the Cow Zone and is anticipated to support commencement of drilling from the first drill bay in Q3 2026.
• A second surface exploration program on the adjacent Proserpine regional greenfield exploration target was ramped up to five drill rigs, with approximately 6,463 metres completed and released, when drilling was paused for caribou calving season. Drilling has recommenced in Q3 2026 with three drill rigs.
• A third surface exploration program on the Yanks Peak target, which is helicopter supported, has also started with two drills in August 2026. The fourth surface exploration program started in Q3 2026 with two drills at the QR Mine.

Tintic Project – Utah, U.S.A. (100%-owned)

• Small-Scale Processing and Test Mining Activities: In the second quarter, the Company continued small-scale heap leaching and direct shipping of mineralized material which generated sales of 5,547 ounces of gold including direct shipping of 4,879 tonnes at an average grade of 38.71 grams per tonne of gold with an average payability factor of 89.5%. An additional 2,954 tonnes of higher-grade mineralized material was stockpiled for direct shipping as of the end of Q2 2026 and was subsequently shipped for processing in July 2026. Test mining is anticipated to continue in Q3 and Q4 2026, and into 2027.
• While management continues to evaluate options for the next steps at the Tintic Project, it is expected that limited activities beyond care and maintenance may occur on the Tintic Project from time to time, including any additional direct shipping of mineralized material from the Trixie test mine.

2026 OBJECTIVES

Note:

1. For the portion of activities to be incurred in 2026.
2. The expenditures disclosed in this table include amounts approved by the Board of Directors as at June 30, 2026, net of amounts already incurred during the six months ended June 30, 2026. Additional expenditures will be required to complete certain of the objectives and are subject to approval by the Board of Directors.

SUBSEQUENT TO Q2 2026

• On July 8, 2026, the Company announced new drill results from eleven (11) surface diamond drill holes totaling 8,971 metres completed between December 2025 and April 2026 as part of an ongoing Cariboo Gold Deeps and near mine gap infill exploration program at the Cariboo Gold Project. Approximately 65% of drilling transected areas outside the current footprint of the Cariboo Gold deposit, and results confirmed the presence of high-grade mineralization to a maximum vertical depth below surface of 718 metres in IM-26-001.
• On July 14, 2026, the Company changed its name from "Osisko Development Corp." to "Osisko Gold Group Inc." and changed the province of its registered office from Québec to Ontario. In connection with the name change, the Common Shares traded under its new trading symbol, "OGG", at the start of trading on July 20, 2026 on each of the TSXV and the NYSE. In addition, the trading symbols for the Company's common share purchase warrants also changed effective at market open on July 20, 2026: (i) warrants trading under "ODVWZ" on the Nasdaq Stock Market ("Nasdaq") and "ODV.WT.U" on the TSXV changed to "OGGWZ" and "OGG.WT.U", respectively; and (ii) warrants trading on the TSXV under "ODV.WT.A" and "ODV.WT.V" changed to "OGG.WT.A", and "OGG.WT.V", respectively.
• On July 22, 2026, the Company announced that, through its wholly owned subsidiary, Barkerville, it entered into a Support and Benefits Agreement (the "Support Agreement") with the District of Wells, British Columbia (the "District"), effective July 21, 2026, to support social and economic initiatives within the District in respect of the Cariboo Gold Project. Over its three-year term, the Support Agreement contemplates voluntary financial contributions by the Company of up to $3.0 million in aggregate, subject to the Company's sole discretion and continued participation under the Support Agreement.
• On July 23, 2026, the Company announced final results and preliminary internal reconciliation analysis of its previously completed infill drilling program in the Lowhee Zone of the Cariboo Gold Project. The preliminary internal reconciliation analysis of two localized areas, comprising an aggregate total of 17,072 metres of infill drilling in 185 diamond drill holes, illustrated deposit variability consistent with expectations, and is subject to ongoing evaluation and modelling.
• On August 5, 2026, the Company announced the first set of new drilling results from fourteen (14) surface diamond drill holes totaling 6,463 metres completed between February and May 2026 as part of an ongoing exploration program on the Proserpine regional greenfield target, located within the broader Cariboo Gold Project property boundary. Results to date confirm the presence of an emerging gold mineralized system comprising high-grade structures and broader zones of lower-grade mineralization that may indicate potential for bulk mining methods.

CAUTIONARY STATEMENTS

Cautionary Statement Regarding Financing Risks

The Company's development and exploration activities are subject to financing risks. As of the date hereof, the Company has exploration and development assets which may generate periodic revenues through test mining but has no mines in the commercial production stage that generate positive cash flows. The Company cautions that test mining at its operations could be suspended at any time. The Company's ability to explore for and discover potential economic projects, and then to bring them into production, is highly dependent upon its ability to raise equity and debt capital in the financial markets. Any projects that the Company develops will require significant capital expenditures. To obtain such funds, the Company may sell additional securities including, but not limited to, the Company's shares or some form of convertible security, the effect of which may result in a substantial dilution of the equity interests of the Company's shareholders. Alternatively, the Company may also sell a part of its interest in an asset in order to raise capital. There is no assurance that the Company will be able to raise the funds required to continue its exploration programs and finance the development of any potentially economic deposit that is identified on acceptable terms or at all. The failure to obtain the necessary financing(s) could have a material adverse effect on the Company's growth strategy, results of operations, financial condition and project scheduling.

Cautionary Statement Regarding Test Mining Not Supported by a Feasibility Study

Certain operations of the Company including prior test mining activities at the Tintic Project's Trixie test mine, have operated without the benefit of a feasibility study including mineral reserves, demonstrating economic and technical viability, and, as a result, there may be increased uncertainty of achieving any particular level of recovery of material or the cost of such recovery. The Company cautions that, historically, such projects have a much higher risk of economic and technical failure. There is no guarantee that commercial production will commence, continue as anticipated or at all or that anticipated production costs will be achieved. The failure to commence or continue production could have a material adverse impact on the Company's ability to generate revenue and cash flow to fund operations. Failure to achieve the anticipated production costs could have a material adverse impact on the Company's cash flow and potential profitability.

Cautionary Statement to U.S. Investors

As a foreign private issuer under U.S. securities laws that files reports under the Canada-U.S. multijurisdictional disclosure system, the Company is permitted to prepare and report information regarding mineral properties, mineralization and estimates of mineral reserves and mineral resources, including the information in its technical reports, financial statements and MD&A, in accordance with Canadian reporting requirements, which are governed by NI 43-101. As such, such information concerning mineral properties, mineralization and estimates of mineral reserves and mineral resources, including the information in its technical reports, financial statements and MD&A, is not comparable to similar information made public by most companies subject to U.S. mineral property disclosure requirements of the U.S. Securities and Exchange Commission ("SEC").

Further to recent amendments, U.S. mineral property disclosure requirements (the "SEC Rules") are now governed by subpart 1300 of Regulation S-K under the U.S. Securities Act. Under the SEC Rules, the SEC now recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources." In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be "substantially similar" to the corresponding standards adopted by the Canadian Institute of Mining, Metallurgy and Petroleum, adopted by the CIM Council ("CIM Standards"), which is the required definition standard adopted by NI 43-101. While the SEC will now recognize "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", U.S. investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable. Further, "inferred mineral resources" have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, U.S. investors are also cautioned not to assume that all or any part of the "inferred mineral resources" exist. Under NI 43-101, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies or economic studies except for preliminary economic assessments. While the above terms are "substantially similar" to CIM Standards, there are differences in the definitions under the SEC Rules and the CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the SEC Rules.

Risks related to the development of the Cariboo Gold Project

The development of a new mining operation, including the construction of processing facilities, tailings storage infrastructure, access roads, power supply and other supporting infrastructure, is a complex and costly undertaking. The Cariboo Gold Project remains in the development stage and there is no certainty that it will be brought into commercial production within anticipated timelines, at anticipated costs, or at all. The results of the Cariboo Technical Report are based on a number of assumptions, including, among others, geological interpretations, estimated mineral resources and mineral reserves, metallurgical recoveries, construction schedules, capital and operating costs, labour and equipment availability, transportation and energy costs, regulatory requirements, and projected commodity prices. These assumptions are inherently uncertain and may prove to be inaccurate.

Actual results, costs and development timelines may differ materially from those currently anticipated due to factors such as: unforeseen geological conditions; changes to mine plan optimization; equipment failures; shortages of skilled labour and contractors; increases in the cost of materials, equipment or energy; design modifications; delays related to permitting or receipt of government approvals; adverse weather or climate conditions; and community and/or Indigenous opposition. In addition, the development of mining projects often requires substantial capital expenditures, and delays or cost overruns may require the Company to seek additional financing, which may not be available on favorable terms or at all. If the Company is unable to complete construction and development of the Cariboo Gold Project on a timely and cost-effective basis, or if operating performance following commissioning is materially lower than expected, the project may fail to achieve anticipated economic results. Any such events could have a material adverse effect on the Company's business, financial condition and results of operations.

Osisko Gold considers its assumptions to be reasonable based on information currently available but cautions the reader that their assumptions regarding future events, many of which are beyond the control of Osisko Gold, may ultimately prove to be incorrect since they are subject to risks and uncertainties that affect Osisko Gold and its business. Such risks and uncertainties include, but are not limited to: the absence of further work stoppages or suspensions at the Cariboo Gold Project; risks relating to third-party approvals, including the issuance of permits by governments, favourable regulatory conditions and approvals, capital market conditions and the Company's ability to access capital on terms acceptable to the Company for the contemplated exploration and development at the Company's properties; the absence of unforeseen ground conditions or other geological challenges; the ability to continue current operations and exploration; regulatory framework and presence of laws and regulations that may impose restrictions on mining; errors in management's geological modelling; the timing and ability of the Company to obtain and maintain required approvals and permits; the results of exploration activities; the availability of necessary equipment, supplies and infrastructure; risks relating to exploration, development and mining activities; the global economic climate; fluctuations in metal and commodity prices; fluctuations in the currency markets; dilution; environmental risks; and community, non-governmental and governmental actions and the impact of stakeholder actions. Osisko Gold is confident a robust consultation process was followed in relation to its received BC Mines Act and Environmental Management Act permits for the Cariboo Gold Project and continues to actively consult and engage with Indigenous nations and stakeholders. While any party may seek to have the decision related to the BC Mines Act and/or Environmental Management Act permits reviewed by the courts, the Company does not expect that such a review would, were it to occur, impact its ability to proceed with the construction and operation of the Cariboo Gold Project in accordance with the approved BC Mines Act and Environmental Management Act permits. Readers are urged to consult the disclosure provided under the heading "Risk Factors" in the Company's annual information form for the year ended December 31, 2025 as well as those risks and factors disclosed in the Company's most recent financial statements and management's discussion and analysis and other public filings filed under Osisko Gold's issuer profile on SEDAR+ (www.sedarplus.ca) and on the SEC's EDGAR website (www.sec.gov), for further information regarding the risks and other factors facing the Company, its business and operations. Although the Company believes the expectations conveyed by the forward-looking statements are reasonable based on information available as of the date hereof, no assurances can be given as to future results, levels of activity and achievements. The Company disclaims any obligation to update any forward-looking statements, whether as a result of new information, future events or results or otherwise, except as required by law. Forward-looking statements are not guarantees of performance and there can be no assurance that these forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.

The filing of the Project Notice represents another significant milestone in advancing the Perron Gold Project toward commercial production. It formally initiates Québec's environmental assessment process for the proposed mine and reflects the Company's continued execution of its development strategy. The Project Notice provides government authorities with a comprehensive overview of the proposed mining operation, including the underground mine, surface infrastructure, environmental setting and overall project design. 

"The submission of the Project Notice is another important step as we move toward developing one of Canada's premier high-grade gold projects," said Victor Cantore, President and Chief Executive Officer of Amex Gold Mining. "Responsible mine development begins long before construction. Our team has invested considerable effort in environmental studies, engineering and community engagement, and we look forward to continuing to work collaboratively with Indigenous communities, local stakeholders and government authorities as we advance Perron through the next stages of development."

Following its review of the Project Notice, the MELCCFP will issue a directive outlining the information to be included in the Environmental Impact Assessment (EIA). The Company has already initiated preparation of the EIA through ongoing environmental baseline studies, engineering, technical evaluations and stakeholder engagement activities. 

The proposed mine is based on the positive Feasibility Study released earlier this year and contemplates a high-grade underground mining operation with mineral processing at an existing regional mill. This development strategy is designed to leverage Perron's exceptional grade while reducing initial capital requirements and accelerating the path toward commercial production. 

Key highlights of the Feasibility Study include:

• Phase 1 Proven and Probable reserves of 1,989 Mt at 12.1 g/t
• Low initial capital cost estimate of $193.9M. During the pre-production period $68.1M of revenue is generated which could offset some capital required
• Average annual gold production of 147,000 oz gold (Au) at an All in Sustaining Cost (AISC) of US$910/oz Au
• Pre-tax NPV of $1,976M and After-tax NPV of $1,127M
• Pre-tax IRR of 160.4% and After-tax IRR of 114.6%
• Cumulative Pre-tax Undiscounted Net Free Cash Flow of $2,492M and Cumulative After-tax Undiscounted Net Free Cash Flow of $1,436M
• Pre-tax payback period of 0.4 years and After-tax payback period of 0.5 years

Note: The Perron FS incorporates the latest Mineral Resource Estimate (2025 MRE - released May 21, 2025). The previous assumes a gold price of US$3,500/oz and a CA$/US$ exchange rate of 1.38:1.

In parallel with the environmental assessment process, Amex continues to advance construction of its fully permitted 40,000-tonne bulk sample program. The bulk sample will generate valuable geological, geotechnical, metallurgical and operational information while further supporting future mine development and optimization.

The Company expects the Project Notice to be made publicly available by the MELCCFP following completion of its administrative review process. Once published by the Ministry, Amex will also make the document available on its website under the Perron Project section, providing shareholders, local communities and other stakeholders with convenient access to the filing.

About Amex

Amex Gold Mining Inc. has made significant high-grade gold discoveries, along with copper-rich volcanogenic massive sulphide (VMS) zones, at its 100%-owned Perron Gold Project. It is located in the territory of Valcanton in northern Quebec, approximately 110 kilometres north of Rouyn-Noranda.

The Perron Project in Quebec consists of 183 contiguous claims for a surface area of 65.72 km². The project hosts several zones of high-grade gold mineralization, VMS mineralization and 'hybrid' gold-rich VMS mineralization. When combined with the adjacent and contiguous Perron West Project and Abbotsford and Hepburn Projects (including additional claims acquired through staking) in Ontario, the consolidated land package spans a district-scale 570.94 km². This extensive property lies within highly prospective geology favourable for both high-grade gold and VMS mineralization.

The Project benefits from excellent infrastructure: it is accessible by a year-round road, located just 30 minutes from an airport, and approximately 6.5 km from the Town of Normétal. Being in close proximity to several processing plants owned by major gold producers also constitutes a strategic advantage.
