“The sale of Blue Moon Norway for equity consideration in ACG maintains our exposure to our assets while simultaneously streamlining our portfolio and eliminating the need to add debt or precious metal streams to our balance sheet,” said Christian Kargl-Simard, Blue Moon’s Chief Executive Officer. “ACG’s unsolicited approach has offered a compelling transaction which immediately recognizes value for our Norwegian assets, provides exposure to strong free cashflow from ACG’s mines, while providing Blue Moon shareholders with the opportunity to participate in future ACG growth. We are pleased to maintain equity exposure for our shareholders to Blue Moon Norway and have full confidence in ACG’s ability to complete the construction of the Nussir mine, with the goal of becoming a mid-tier diversified mining company. Meanwhile the Company’s strong unlevered balance sheet will fund its four U.S. critical metals mines towards production, with shareholders having exposure to nine different commodities.”

“ACG is very pleased to build upon Blue Moon’s progress and excited to take the Nussir mine into its next phase - production. We look forward to working together with Nussir’s team and communities to fulfill our goals and commitments,” said Artem Volynets, ACG’s Chairman and Chief Executive Officer. “We also especially welcome Blue Moon shareholders to our register and to the fast-growing copper company with a vision to consolidate the sector.”

Strategic Rationale

By divesting Blue Moon Norway, the Company achieves several important objectives: 

• Crystallizes Value: The Transaction crystallizes value at an attractive valuation for Blue Moon Norway, while preserving ongoing participation for Blue Moon shareholders
• Ongoing Exposure to Cash Flow Positive, European Copper Company: Blue Moon shareholders receive immediate exposure to a copper producing, cash flow positive European growth company, leveraging ACG’s mine building team while maintaining exposure to Blue Moon Norway and with a cost of capital substantially lower than Blue Moon’s available facilities
• Strategic Refocus: The Transaction cleanly repositions Blue Moon’s portfolio to focus on the Company’s U.S. critical minerals assets, with the focus to put the Springer and Apex Mines into production by the end of 2027
• Diversified Commodity Exposure: Blue Moon will maintain exposure to nine different commodities, with an overall increase in exposure to precious metals and a slight decrease in exposure to copper, without any precious metals streams or hedging
• Strengthened Balance Sheet: Blue Moon will repay the amounts drawn as part of the Nussir project finance package with Hartree Partners, LP and Oaktree Capital Management at the closing of the Transaction. Existing cash resources and undrawn funding commitments from The Elmet Group Co. are currently approximately US$125 million. All of the Company’s U.S. critical metals assets will be unencumbered by security interests

Transaction Details

Pursuant to the Agreement, ACG will acquire Blue Moon Norway from Blue Moon for US$220 million in Shares, subject to post-closing net debt, working capital, intercompany and other customary adjustments. Any closing adjustments are to be settled in cash.    

Blue Moon expects to receive approximately 8,853,632 ACG Shares representing 27.6% and 21.8% ACG ownership of on a basic and fully diluted basis, respectively.  Blue Moon has agreed to a lockup period of six months during which time it will not sell shares of ACG unless mutually agreed. The Parties will work together to distribute the Shares to the shareholders of Blue Moon within 12 months of closing of the Transaction.

Skott Mealer, Blue Moon’s President and COO, is expected to join the ACG board as an observer upon closing of the Transaction. The existing Blue Moon construction team in Norway will work with the incoming ACG construction team to ensure a smooth transition. 

Closing of the Transaction remains subject to customary closing conditions, including ACG shareholder approval; the approval of the TSX Venture Exchange, in the case of Blue Moon; and other customary approvals. In relation to ACG shareholder approval, 80.7% of ACG shareholders have entered into irrevocable voting support agreements to vote in favour of the required resolutions, with 75.0% required to pass the resolutions. Blue Moon shareholder approval will not be required. Subject to the satisfaction of these conditions, the Transaction is anticipated to close by November 30, 2026. This is an arms-length Transaction and no finders’ fees are being paid. No concurrent financing is required by ACG to complete the Transaction.

Board of Directors Recommendation and Fairness Opinion

After consultation with its outside financial and legal advisors, the Board of Directors of Blue Moon have unanimously approved the Transaction.  

ATB Cormark Capital Markets has provided a fairness opinion to the Blue Moon Board of Directors, to the effect that, as of the date thereof, and based upon and subject to the assumptions, limitations and qualifications therein, the consideration to be received is fair, from a financial point of view, to Blue Moon.

Advisors and Counsel

In connection with the Transaction, Canaccord Genuity Corp. is acting as financial adviser to Blue Moon, with Bennett Jones LLP and Simonsen Vogt Wiig acting as legal advisors to Blue Moon.

The 2026 drill program comprised 11 diamond drill holes totalling 4,219 metres (m), including five infill holes at the Three Bluffs deposit (Figure 1). The reported results come from infill drilling designed to increase drill density within the main portion of the existing Three Bluffs mineral resource and support improved confidence in geological and grade continuity.

Significant drill highlights, shown in true widths, include:

• Hole 26TB158 intersected 3.88 grams per tonne (“g/t”) gold (“Au”) over 17.82 m, including 18.78 g/t Au over 3.30 m
• Hole 26TB161 intersected 0.77 g/t Au over 98.60 m, including 65.60 g/t Au over 0.56 m, the widest mineralized interval drilled to date
• Hole 26TB160 intersected 0.92 g/t Au over 31.45 m, including 12.35 g/t Au over 1.18 m, and 0.99 g/t Au over 28.83 m
• Hole 26TB163 intersected 0.72 g/t Au over 36.58 m, including 2.65 g/t Au over 3.31 m
• All five holes intersected the Three Bluffs shear zone, with widths ranging from 17 m to 99 m
• 4,219 m (or 11 drill holes), including one abandoned hole, for the 2026 Committee Bay program has been completed. Assay results are pending for five of these holes, two of which are extension holes. 

Results are highlighted by drill hole 26TB158, which intersected 3.88 g/t gold over 17.82 m, including a high-grade core of 18.78 g/t gold over 3.30 m, at a relatively shallow depth of 190 m. The hole was drilled within a broadly spaced area measuring 120 m by 220 m, demonstrating the continuity of mineralization across a large volume. The hole also returned a broad zone of lower-grade mineralization grading 0.39 g/t gold over 38.97 m immediately down-hole within the principal intercept (Figure 3). This intercept further demonstrates the scale and continuity of mineralization within the deposit and supports confidence in the Company’s geological model. The results are expected to be incorporated into the upcoming mineral resource update, contributing to increased resource confidence and supporting ongoing advancement of the project.

Drilling also returned broad zones of gold mineralization across the deposit, highlighted by hole 26TB161, which intersected 0.77 g/t gold over 98.60 m, including 65.60 g/t gold over 0.56 m, representing the widest mineralized interval drilled to date at Three Bluffs. Additional results include hole 26TB160, which intersected two mineralized zones grading 0.92 g/t gold over 31.45 m, including 12.35 g/t gold over 1.18 m, and 0.99 g/t gold over 28.83 m, including 3.50 g/t gold over 1.85 m (Figure 4). While hole 26TB163 returned 0.72 g/t gold over 36.58 m, including 2.65 g/t gold over 3.31 m, and hole 26TB162 returned 0.67 g/t gold over 17.36 m and 0.45 g/t gold over 20.98 m (Figure 4).

All holes disclosed in this news release, as well as the pending holes from the 2026 Committee Bay program, will be incorporated into the upcoming mineral resource estimate update for the Project. To date, 11 drill holes totalling approximately 4,219 metres have been completed, of which one hole was abandoned, and five holes are pending assay results. While the five holes reported in this release are infill holes, two of the five pending holes were designed as extension holes to define the extent of mineralization. The infill results give the Company confidence in the deposit as it continues exploring at depth and testing the full limits of the Three Bluffs resource.

“All five of our holes hit the Three Bluffs shear zone, which is exactly what this drill program was designed to confirm,” commented Tim Clark, CEO of Fury. “Hole 26TB158 stands out, returning 3.88 g/t gold over nearly 18 metres with a high-grade core of 18.78 g/t over 3.3 metres, and is a good example of the broad, continuous mineralization that has become a key differentiator of the Committee Bay project. The results strengthen our confidence in the scale of the Project as we continue to grow ounces ahead of the upcoming mineral resource update. With extension results pending, we look forward to further defining the size and potential of the Three Bluffs deposit.”

Table 1: Recent Drill Highlights

True widths are calculated using an interpreted mineralized domain of dip 80–89° as indicated for each hole. Reported intervals are length-weighted average gold grades. Composites require a minimum grade×thickness of 0.25 g/t·m, a minimum grade of 0.25 g/t gold and a maximum of 6 m of consecutive internal dilution; sub-intervals require a minimum grade×thickness of 5 g/t·m, a minimum grade of 2.00 g/t gold and a maximum of 2.5 m of consecutive internal dilution.

Three Bluffs Deposit

The high-grade Three Bluffs Gold deposit is located centrally within the Committee Bay project and is estimated to contain 524,000 oz of gold in 2.1 million tonnes (Mt) at 7.85 g/t gold in the indicated mineral resource category and 720,000 oz in 2.9 Mt of gold at 7.64 g/t gold in the inferred mineral resource category (see Committee Bay NI 43-101 report “Technical Report on the Committee Bay Project, Nunavut Territory, Canada” dated September 11, 2023).

Valérie Doyon, P.Geo, VP of Geology at Fury, is a “qualified person” within the meaning of Canadian mineral projects disclosure standards instrument 43-101 and has reviewed and approved the technical disclosures in this press release.

Committee Bay Drilling QA/QC Disclosure

Intercepts at Three Bluffs were calculated using a minimum of a 2.0 g/t gold cut off at the beginning and end of the intercept and allowing for no more than 2.5 consecutive metres of less than 2.0 g/t gold. Minimum length of the composite allowed was one metre.

2026 Core (Diamond) Drilling

Analytical samples were taken by sawing NQ diameter core into equal halves on site and sent one of the halves to ALS Lab in Yellowknife, NWT for preparation and then to ALS Lab in Vancouver, BC for analysis. All samples are assayed using 50g nominal weight fire assay with atomic absorption finish (Au-AA26) and multi-element four acid digest ICP-AES/ICP-MS method (ME-MS61). QA/QC programs using internal standard samples, field and lab duplicates and blanks indicate good accuracy and precision in a large majority of standards assayed.

Ganoza, CEO and Director of Fortuna, commented, “Following our July final investment decision on the 30% plant expansion at our flagship Séguéla mine, and with Diamba Sud advancing through the final stages of permitting, we are progressing along a clear growth path. Together, these projects underpin our target of approximately 60% growth in annual gold production to an annualized rate of 500,000 ounces from mid-2028.”

Permits 

Fortuna is pleased to report that it received the Notice of Admissibility for its Diamba Sud Exploitation Permit application from Senegal’s Ministry of Mines and Geology on November 2, 2026, following initiation of the application process in February 2026. The notice confirms that the Ministry has completed the review of the application documentation, and the file complies with all regulatory requirements, marking an important final step toward the granting of the Exploitation Permit. The Company and the Ministry have worked constructively to advance the application to this stage. With this milestone completed, the Company now expects the Government´s internal approval process for the final Exploitation Permit to be completed during the fourth quarter of 2026.

The project has already received the environmental decree from Senegal’s Ministry of Environment and Ecological Transition approving its Environmental and Social Impact Assessment, as announced on June 15, 2026. Fortuna is advancing early works and committing capital to protect the project schedule and its target of first gold in mid-2028. The Company anticipates making a formal final investment decision (“FID”) upon receipt of the Exploitation Permit.

Mining Convention 

Fortuna is at an advanced stage of negotiations with the State of Senegal on a new Mining Convention for the Diamba Sud project based on Senegal’s 2016 Mining Code, together with additional provisions intended to establish a fiscal stability framework for a ten-year period. The Convention remains subject to finalization and the required Government approvals.

Construction Planning and Early Works Advancing Full-scale construction of the mine remains subject to receipt of the Exploitation Permit, Board approval of the FID and some local level customary construction approvals. The results of the positive feasibility study (“FS”) announced on June 29, 2026 demonstrated the project’s technical and economic viability (refer to Fortuna news release dated June 29, 2026, “Fortuna delivers robust Feasibility Study for the Diamba Sud Gold Project in Senegal: After-tax IRR of 60% and NPV5% of US$1 billion using US$3,500/oz”).   Early works completed or underway to support the project schedule include: 

• Assembly of the owner’s construction team, with a core of professionals largely drawn from the team that successfully delivered Fortuna´s flagship Séguéla mine in Cote d’Ivoire
• Selection of SENET, a leading African project management and engineering company, as the project’s engineering, procurement and construction management contractor, and award of a limited order to proceed to advance early works
• Completion of front-end engineering and design
• 15% progress on detailed engineering for the processing plant
• Purchase orders placed and down payments for critical long-lead equipment, including the semi-autogenous grinding (“SAG”) mill, primary crusher, and carbon-in-leach tank plate work
• Manufacturing of the power station's heavy fuel oil (“HFO”) and light fuel oil (“LFO”) generators with the LFO generators passing factory acceptance testing and shipped
• Tendering and award of key construction packages, including, bulk earthworks for process plant, water storage facility, tailings storage facility, power station, and fuel storage facilities
• New accommodation camp earthworks 80% complete, civil works 40% complete and buried services nearing completion
• Land compensation and clearing for major infrastructure footprints

  Subject to receiving the Exploitation Permit and approval of the FID in 2026, the planned key project milestones are summarized below:

Highlights

• Fenn-Gib Gold Project designated under Ontario’s the Ministry of Energy and Mines’ “One Project, One Process” framework
• Through the 1P1P framework, the Ministry of Energy and Mines acts as a single point of contact to coordinate all necessary provincial approvals and Indigenous consultation to reduce government review times by 50 per cent[2]
• The 1P1P framework, which supports responsible, fast-tracked mining development while maintaining rigorous standards and Indigenous consultation, is fundamental to Mayfair’s strategy for advancing Fenn-Gib through permitting, design, and into construction and operations faster than previous industry timelines
• Through the 1P1P framework, Mayfair expects to secure permits required to make a construction decision as early as 2028
• Fenn-Gib is positioned to generate significant regional economic benefits during construction and throughout commercial operations, which could begin as early as 2030.

“For too long, permitting delays stood in the way of getting Ontario’s resources to market,” said Stephen Lecce, Minister of Energy and Mines. “One Project, One Process is singlehandedly changing that - cutting duplication by half and delivering a one stop shop for mining permitting including for Mayfair Gold’s Fenn-Gib project which is expected to create over 700 jobs and add approximately $3 billion to our GDP. To compete, we must be the best, which is why our government is planning to further accelerate permitting this Fall, to get mines built faster, unlocking billions in investment to create more, good-paying jobs right here at home. From second slowest jurisdiction to open a mine in the world to emerging as one of the best in the industrialized world, our government is challenging the status quo so that we emerge as the strongest and a more sovereign energy powerhouse.” 

Drew Anwyll, P.Eng., Chief Executive Officer of Mayfair, stated: “Our designation under the 1P1P framework recognizes the rigorous work completed to date and the quality of the baseline data our team has collected, compiled, and interpreted in support of the Fenn-Gib Gold Project. We look forward to working collaboratively with the Apitipi Anicinapek Nation (“AAN”), the Ministry of Energy and Mines (“MEM”), and the identified Indigenous and local communities as we advance the Project through this permitting process. We are proud to have achieved the milestone of 1P1P designation, and we look forward to advancing Fenn-Gib as a Made-in-Ontario gold project.”

The 1P1P framework is a whole-of-government approach that consolidates provincial permitting, authorization, and approval processes for designated mine development projects in Ontario into a single, coordinated timeline. This approach is designed to improve predictability and reduce administrative duplication. It also coordinates Indigenous consultation at the project level, consistent with the Crown’s duty to consult under section 35(1) of the Constitution Act, 1982. Fewer, coordinated processes reduce the administrative burden on Indigenous communities; they do not reduce consultation itself.

This framework operates as an administrative overhaul to streamline approvals by establishing a single point of contact - the Mine Authorization and Permitting Delivery Team (“MAPDT”) under the MEM. The dedicated MAPDT will provide specialized project management support to Mayfair to deliver predictable permitting timelines for Fenn-Gib with a clear, transparent, and dynamic pathway while maintaining the Crown’s full duty to consult and rigorous environmental standards.

Ruben Wallin, P.Eng., SVP Sustainability for Mayfair, commented: “The 1P1P designation marks an important milestone for the project and the company. The calibre of the people we have worked with at the Ministry has been evident throughout this process. I look forward to continuing to work closely with the MEM, AAN and Indigenous community partners, and other stakeholders to deliver the lasting benefits that we believe this project and our company can provide to the region.”

Mayfair’s development strategy is anchored in targeting high-grade mineralization located at and near surface. This approach is designed to reduce construction risk and improve execution certainty. Together with the 1P1P framework and the Provincial Class Environmental Assessment process, the strategy provides a clear pathway to advance Fenn-Gib efficiently through permitting and design, into construction, and ultimately to free cash flow¹ while maintaining the optionality and the flexibility to reinvest future cash flows¹ in additional growth opportunities.

About Mayfair Gold

Mayfair Gold is a Canadian development-stage gold company focused on advancing the 100%-owned Fenn-Gib Project in the Timmins region of Northern Ontario. Fenn-Gib hosts a 4.3-million-ounce indicated mineral resource of gold (181.3Mt at an average grade of 0.74 g/t) and the expected strategy outlined in the 2026 Pre-Feasibility Study (the “PFS”)[3] is to develop the Project under the provincial permitting process, targeting the higher-grade 1-million-ounce probable mineral reserve (25.1Mt at an average grade of 1.29 g/t) sitting near-surface, highlighting the optionality and scalability provided by the deposit. The PFS also outlines the potential to develop Fenn-Gib into a new Canadian gold producer, with initial development capital of C$450 million, a base-case payback period of 2.7 years, and cumulative free cash flow1 of US$896 million over the first six years of production based on a US$3,100/oz gold price. The Company is advancing permitting activities, detailed engineering, and stakeholder engagement with the goal of starting construction in 2028 with initial production in 2030. The Company also remains focused on exploration around the broader land package with the goal of enhancing mineral resource scale and growth opportunities.

Highlights:

• Infill Drilling Underway: Three diamond core drill rigs have commenced drilling at Sao Jorge to execute an initial 6,000-metre infill drilling campaign.
• Objective to Enhance existing Mineral Resource Confidence: The objective of the program is to provide additional data for an updated mineral resource estimate ("MRE") with the goal of enhancing confidence in, and upgrading to indicated classification, the existing inferred resources within the pit shell currently contained in the Project's existing preliminary economic assessment (the "PEA").
  1. The Company anticipates that the results of the infill drilling will be used to prepare an updated MRE to support the PFS, which it currently anticipates will be completed in the first half of 2028.
• Project Studies: The infill drilling will produce fresh core samples required for future metallurgical test work, which will inform trade-off studies to determine the optimum process path for São Jorge mineralized material.
• De-Risking: Planning is also underway for geotechnical and hydrogeological drilling around the planned open pit mine, and condemnation drilling beneath proposed site infrastructure locations. 

Alastair Still, Chief Executive Officer of GoldMining, commented: “Following the recent addition of our new Project Director to lead the Project’s advancement, we are thrilled to officially launch the Pre-Feasibility Study, and we now have three core drills turning at São Jorge. This initial 6,000-metre program is designed to improve our resource confidence and to provide the geotechnical and metallurgical data necessary to optimize our mine plan and flowsheet. We believe we are well-positioned to continue to advance and de-risk this asset.”

2026 Infill Drilling Program

The planned initial 6,000-metre diamond drilling program is designed to reduce drill spacing to provide higher confidence in the continuity of mineralization in areas where mineral resources are presently classified as inferred mineral resources. These zones are generally located around the margins of the main mineralized core of the São Jorge deposit. The objective is to improve interpreted geological and geostatistical continuity in order to classify all mineral resources contained within the pit shell of the Project's PEA, and planned PFS open pit mine design in the measured or indicated mineral resource categories. 

In addition to resource conversion, the program will yield fresh core samples to facilitate advanced mineralogical sampling and metallurgical testing, as well as essential data for the geotechnical stability analysis of the proposed open pit and major site facilities. Three rigs are now active on the Program.

The PFS will build upon the base case established in the PEA and is intended to further evaluate the Project's economic viability and to refine capital and operating cost estimates.

About São Jorge

The São Jorge Gold Project is located in the Tapajós gold district in Pará State, Brazil, adjacent to regional highway BR-163. It is a granite-hosted, intrusion-related gold mineral system. 

On June 11, 2026, the Company announced a PEA for São Jorge that envisaged a conventional open-pit operation and gravity/leach circuit processing 5,500 tonnes per day ("tpd") (1.9 million tonnes per annum ("Mtpa")) over a 10.6-year mine life. The PEA modelled a base case after-tax net present value at a 5% discount rate ("NPV5%") of US$532 million and an after-tax internal rate of return ("IRR") of 42.4%, utilizing a base case gold price of US$3,500 per ounce ("oz"), supported by a stable production profile averaging 51,250 oz of gold annually. 

The PEA is preliminary in nature and includes inferred mineral resources, which are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the PEA, including the conceptual economics set out therein, will be realized.

Further information regarding the Project, including the PEA referenced in this news release, please refer to the technical report titled “NI 43-101 Technical Report and Preliminary Economic Assessment for the São Jorge Gold Project, Pará State, Brazil” with an effective date of June 9, 2026 (the "Technical Report"), which is available under the Company’s profiles on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov.

Cautionary Statement on Forward-looking Statements

Certain of the information contained in this news release constitutes "forward-looking information" and "forward-looking statements" within the meaning of applicable Canadian and U.S. securities laws ("forward-looking statements"), which involve known and unknown risks, uncertainties and other factors that may cause the Company’s actual results, performance and achievements to be materially different from the results, performance or achievements expressed or implied therein. Forward-looking statements, which are all statements other than statements of historical fact, include, but are not limited to, statements regarding the scope, timing and expected outcomes of the PFS, including its anticipated completion in the first half of 2028; the timing, scope and objectives of the infill drilling program, and the objective to upgrade existing mineral resource estimates; the potential for any future development decision; the results of the PEA; the Company’s plans and expectations regarding future opportunities and proposed work and future studies at the Project; and the Company’s other plans and expectations regarding the Project. Forward-looking statements are based on the then-current expectations, beliefs, assumptions, estimates and forecasts about the business and the markets in which GoldMining operates, including assumptions that drilling and study work will proceed as planned, that contractors, equipment and personnel will be available on a timely basis, that drilling results will support the planned resource conversion, and that required permits and financing will be obtained. Investors are cautioned that all forward-looking statements involve risks and uncertainties, including: the inherent risks involved in the exploration and development of mineral properties; fluctuating metal prices; unanticipated costs, expenses and delays; risks related to government and environmental regulation, social, permitting and licensing matters; and uncertainties relating to the availability and costs of financing needed in the future. These risks, as well as others, including those set forth in GoldMining’s Annual Information Form for the year ended November 30, 2025, and other filings with Canadian securities regulators and the SEC, could cause actual results and events to vary significantly. Accordingly, readers should not place undue reliance on forward-looking statements. There can be no assurance that forward-looking statements, or the material factors or assumptions used to develop such forward-looking statements, will prove to be accurate. The Company does not undertake to update any forward-looking statements, except in accordance with applicable securities law.

Paul Weedon, Senior Vice President of Exploration, commented, “The first holes at Kabewest have returned broad mineralized intervals, including 1.9 g/t Au over an estimated true width of 64 meters from 19 meters in drill hole FBRC0008. These results provide strong support for our geological interpretation and show clear similarities to the breccia-hosted mineralization at Diamba Sud,” Mr. Weedon continued, “With approximately 70 percent of assays received, the results to date continue to build confidence in the interpreted controls on mineralization and in Bambadji’s potential to expand Diamba Sud.” Mr. Weedon concluded, “We look forward to receiving the remaining assays in the coming weeks and incorporating the complete dataset into our work toward an initial Inferred Mineral Resource estimate, planned for publication in the first quarter of 2027.”

Kabewest Drilling Highlights

FBDD0001: 1.2 g/t Au over an estimated true width of 23 meters from 75 meters

FBDD0006: 1.8 g/t Au over an estimated true width of 29.5 meters from 393 meters

FBDD0008: 3.2 g/t Au over an estimated true width of 24 meters from surface, including 
 11.3 g/t Au over an estimated true width of 1.5 meters from 8 meters and 12.2 g/t Au over an estimated true width of 0.7 meters from 30 meters

FBDD0009: 1.4 g/t Au over an estimated true width of 22 meters from 65.5 meters, and 1.3 g/t Au over an estimated true width of 23 meters from 107 meters

FBRC0003: 3.1 g/t Au over an estimated true width of 24.2 meters from 4 meters, including 
 15.1 g/t Au over an estimated true width of 0.7 meters from 25 meters

FBRC0005: 1.4 g/t Au over an estimated true width of 29.6 meters from surface

FBRC0008: 1.9 g/t Au over an estimated true width of 64 meters from 19 meters, including 
 16.3 g/t Au over an estimated true width of 1.5 meters from 24 meters

The Bambadji Project is located immediately adjacent to the Diamba Sud Gold Project. The initial Kabewest drilling program, comprising 45 reverse circulation (“RC”) and diamond drill (“DD”) holes totalling 10,524 meters, has been completed. This work forms the first phase of a broader $8 million, 51,000-meter drilling program planned across the Bambadji Project through the end of 2026. The program is focused on at least eight priority prospects (refer to Figure 1 and Fortuna news release dated August 10, 2026, “Fortuna acquires highly prospective Bambadji Project in Senegal from Barrick and IAMGOLD”).

Figure 1: Bambadji Project: Location of priority exploration prospects and proximity to the Diamba Sud Gold Project proposed plant site

Broad mineralized intervals from the initial Kabewest drilling include 1.9 g/t Au over an estimated true width of 64 meters from 19 meters in drill hole FBRC0008 (refer to Figure 2), 1.4 g/t Au over an estimated true width of 29.6 meters in drill hole FBRC0005 (refer to Figure 3) and 3.1 g/t Au over an estimated true width of 24.2 meters from 4 meters in drill hole FBRC0003 (refer to Figure 4). These results strengthen the current geological interpretation and demonstrate geological continuity with the breccia-hosted mineralization at the nearby Diamba Sud deposits. Mineralization has been intersected over more than 600 meters of strike and remains open along strike and at depth, providing clear opportunities for systematic follow-up drilling.

Approximately 70 percent of assays have been received, with the balance expected in the coming weeks. Geological model updates are progressing and will incorporate the complete assay dataset to support preparation of an initial Inferred Mineral Resource estimate for Kabewest. Subject to completion and review of the remaining technical work, the Company expects to include the estimate in its annual Mineral Reserve and Mineral Resource update planned for publication in the first quarter of 2027.

Figure 3: Bambadji Project: Kabewest prospect, cross section 250NE

Figure 4: Bambadji Project: Kabewest prospect, cross section 50NE

As observed at Diamba Sud, mineralization at Kabewest is generally associated with hydrothermal breccia units, hematite-silica-altered limestone, and extensive pyrite development. These features reinforce the interpreted structural controls on gold-bearing fluids within the Falémé domain, which hosts both projects. The comparable geological features identified across the adjacent Diamba Sud and Bambadji Project support continued systematic exploration along the Senegal-Mali Shear Zone.

Following completion of the initial phase of Kabewest drilling, the six drill rigs have been relocated to the Wari and Latifa prospects (refer to Figure 1), where three drill rigs at each prospect are testing areas defined by historical, widely spaced reconnaissance drilling. Work is also progressing to refine targets for the 2027 field season using geochemical and geophysical data across more than 60 kilometers of strike within the Bambadji Project, where three mineralized trends have been identified. Historical drilling along these trends is generally shallow and widely spaced, leaving several multi-kilometer gaps that provide priority areas for evaluation as part of Fortuna’s 2026 and 2027 exploration programs.

Quality Assurance & Quality Control (QA - QC) 

All drilling data completed by the Company utilized the following procedures and methodologies. All drilling was carried out under the supervision of the Company’s personnel.

All reverse circulation (RC) drilling used a 5.25-inch face sampling pneumatic hammer with samples collected into 60-liter plastic bags. Samples were kept dry by maintaining enough air pressure to exclude groundwater inflow. If water ingress exceeded the air pressure, RC drilling was stopped, and drilling converted to diamond core tails. Once collected, RC samples were riffle split through a three-tier splitter to yield a 12.5 percent representative sample for submission to the analytical laboratory. The residual 87.5 percent samples were stored at the drill site until assay results were received and validated. Coarse reject samples for all mineralized samples corresponding to significant intervals are retained and stored on-site at the Company-controlled core yard.

All diamond drilling (DD) drill holes started with HQ sized diameter, before reducing to NQ diameter diamond drill bits on intersecting fresh rock. The core was logged, marked up for sampling using standard lengths of one meter or to a geological boundary. Samples were then cut into equal halves using a diamond saw. One half of the core was left in the original core box and stored in a secure location at the Company core yard at the project site. The other half was sampled, catalogued, and placed into sealed bags and securely stored at the site until shipment.

All RC and DD samples were transported by Company vehicle or commercial courier to ALS Global’s preparation laboratories in Kedougou, Senegal with prepared sample pulps then transported via commercial courier to ALS Global’s analytical facility in Ouagadougou, Burkina Faso. Routine gold analysis using a 50-gram charge and fire assay with an atomic absorption finish was completed for all samples. Samples returning assays >10 ppm Au were reanalyzed using a 50-gram charge and fire assay with a gravimetric finish. Quality control procedures included the systematic insertion of blanks, duplicates and sample standards into the sample stream. In addition, the ALS Global laboratory inserted its own quality control samples.

Cautionary Note to United States Investors Concerning Mineral Resources and Reserves

Technical disclosure regarding the Company’s properties included in this news release has been prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards on Mineral Resources and Mineral Reserves. Canadian standards, including NI 43-101, differ from the requirements of the Securities and Exchange Commission, and information included herein may not be comparable to similar information disclosed by U.S. companies.

Notes:

1. EOH: End of hole

2. Depths and widths reported to nearest significant decimal place 

3. NSI: No significant intercepts

4. ETW: Estimated true width

5. RC: reverse circulation drilling | DD: diamond drilling

Drill highlights from the conversion drilling completed to date include:

• 114.07 g/t Au over 1.00 m including 227.46 g/t Au (and 17.90 g/t Ag) over 0.50 m at a vertical depth of ~187 m in hole PE-26-959 of the Denise Zone
• 29.86 g/t Au over 2.50 m including 126.24 g/t Au (and 20.80 g/t Ag) over 0.50 m at a vertical depth of ~220 m in hole PE-26-957 of the Denise Zone
• 11.42 g/t Au over 1.85 m including 23.79 g/t Au (and 5.00 g/t Ag) over 0.85 m at a vertical depth of ~471 m in hole PE-26-960 of the Champagne Zone

The initial stages of the resource conversion program have focused on the first 600 vertical metres of the Denise and Champagne Zones. Note that the vast majority of resources in the top 600 m of the Champagne Zone were already in the M&I category, so only two conversion drill holes were required, meaning that almost all conversion drilling completed to date has been focused on the Denise Zone. 

In addition to the resource-conversion drilling, exploration drilling east of the current Denise Zone has potentially expanded the mineralized footprint by approximately 320 m. Drill hole PE-26-936 returned 3.33 g/t Au over 12.70 m, including 47.73 g/t Au (and 14.50 g/t Ag) over 0.80 m at a vertical depth of ~172 m (see Figure 2). This is an encouraging exploration development, as minimal drilling has been completed in the extreme southeast corner of the Beaupré Block. As the Denise Zone expands east and the Team Zone advances to the southeast, the possibility for the two zones to meet one another becomes more realistic. Further exploration drilling in the southeast extremity of the Beaupré Block is therefore planned. 

"The resource conversion drill program is off to a strong start," said Aaron Stone, Vice President Exploration of Amex Gold Mining. "Our initial focus has been on the first 600 vertical metres of mineralization within the Champagne and Denise zones. Given that the vast majority of Champagne Zone resources within this interval were already classified as Measured and Indicated resources, only two drill holes were required there, with most of the program to date focused on the Denise. High-grade results encountered in holes such as PE-26-957 and PE-26-959 are particularly encouraging given that the targeted grade of the inferred stopes averages approximately 2.5 g/t Au. These results present an opportunity to not only upgrade these resources but also to potentially add ounces in the targeted area. These results in the conversion program are important in increasing confidence in the economics of the second phase of the operation."

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.

Qualified Persons and QA/QC

The technical information in this news release has been reviewed and approved by Aaron Stone, P.Geo (OGQ – 2170, PGO – 3708), Vice President, Exploration of the Company and Jérôme Augustin Ph.D. P.Geo., (OGQ – 2134), an Independent Qualified Person as defined by Canadian NI 43-101 standards. The drilling campaign and the quality control program have been planned and supervised by Jérôme Augustin. Core logging and sampling were completed by Laurentia Exploration.

The quality assurance and quality control protocols include insertion of blank or standard samples every 10 samples on average, in addition to the regular insertion of blank, duplicate, and standard samples accredited by Laboratoire Expert and AGAT Laboratories Ltd., during the analytical process.

For all analyses targeting gold mineralization, gold values are estimated by fire assay with finish by atomic absorption. Values over 3 ppm Au are reanalyzed by fire assay with finish by gravimetry by Laboratoire Expert Inc., Rouyn-Noranda. Samples containing visible gold mineralization are analyzed by metallic sieve. For additional quality assurance and quality control, all samples were crushed to 90% less than 2 mm prior to pulverization, in order to homogenize samples which may contain coarse gold.

For all analyses targeting gold and base metals mineralization, gold, platinum and palladium values are estimated by lead fusion fire assay with atomic absorption spectroscopy finish, by AGAT Laboratories. Metals and trace elements values are estimated using four acid digestion with ICP-OES/MS finish, by AGAT Laboratories. For additional quality assurance and quality control, all samples were crushed to less than 2 mm, and then to 85% passing 75 µm, in order to homogenize samples which may contain coarse gold.

Note: All highlighted intervals are downhole lengths; approximate calculated true widths are expressed as percentages of downhole interval lengths (see Table 2).

“This year's program aims to pinpoint areas with high-grade mineralization, particularly where the current resource model shows unmineralized regions. Drillhole AX-26-921 produced significant high-grade intersections that suggest potential for expansion and improved grades between the Airstrip and Powerline Deposits,” stated Tara Christie, President and CEO. “Specifically, AX-26-921 returned several mineralized intervals, including 1.34 g/t Au over 20.2 m and 1.18 g/t Au over 27.5 m, indicating continuity of the higher-grade zones at depth in the Airstrip deposit below the gap. These results reinforce that expansion opportunities remain at AurMac, alongside the early discoveries at Nitra. Banyan’s next exploration phase will focus on identifying the prime areas within AurMac that will contribute to our initial 10-year grade and production profile, leading to further studies beyond our Preliminary Economic Assessment.” 

Figure 1: Plan map of AurMac, Yukon, Canada. Results for drillholes AX-26-904, -908, -909, -913, -915 and -921 are reported in Table 1. A plan map of Airstrip (Figure 2) and cross-sections (Figures 3 and 4) show the detailed distribution of drillholes in Airstrip and the geometry of high-grade mineralization.

Figure 2: Plan map of Airstrip. Cross-sections are denoted by blue lines.  Drillhole AX-26-921 in cross-section 466900mE (Figure 3) highlights the expansion potential for high-grade domains in the gap between the Airstrip and Powerline Deposits near the southern extent of the conceptual Mineral Resource Estimate (“MRE”) pit. Drillholes AX-26-904, -908, -909, and -915 in cross-section 467300mE (Figure 4) highlight the expansion potential for high-grade domains to the east in Airstrip. 

Mineralization at Airstrip is predominantly hosted in calcareous metasedimentary rocks that readily undergo calc-silicate alteration and sulphide replacement mineralization (Figure 5). Calcareous metasedimentary rocks overlie quartzites. Domains Cal_1 and Cal_2 (calcareous metasedimentary rocks) are the primary host for gold mineralization at Airstrip, with extensional quartz veins hosted in the quartzite (“QTZT”). A notable zone of mineralization has been intersected in the footwall of Airstrip, with high-grade mineralization and visible gold (Figure 6) identified in extensional quartz veins hosted in quartzite stratigraphically below the main Airstrip deposit (Figure 3). Potential for footwall domains in the Airstrip area has been identified in previous drilling and is being tested this drill season.

Figure 3: Cross-section 466900mE through Airstrip. Drillhole AX-26-921 highlights potential expansion of high-grade domains in the gap zone between Airstrip and Powerline. Additional down-dip drilling is planned to further test the extent of high-grade mineralization at depth within and just south of the conceptual pit boundary. The MRE block model is constrained by mineralized and lithological domains. Mineral Resource blocks are 10 m x 10 m x 5 m. 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.

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 3 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 3: 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 and 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.

  2. All deposits at Enchi remain open for expansion along strike and to depth.

Greg Smith, VP Exploration of Newcore stated, "We continue to encounter high-grade gold mineralization at the Nyam Gold Deposit at our Enchi Gold Project in Ghana. Drilling targeted extensions to a southern high-grade shoot identified at Nyam, with strong results supporting the thesis that Enchi has the potential to grow in size and scale as we continue to define the high-grade potential at depth. This drilling intersected gold mineralization below the reserve pits, highlighting the opportunity for resource conversion and the potential for future mineral reserve growth to support future economic studies. We look forward to continuing to prove out Enchi’s value through the drill bit, with the on-going 80,000 metre drill program an important step in defining the Project’s longer-term potential."

This release reports results for 4 DD holes totalling 1,192 m (NBDD092 to NBDD095A) targeting the Nyam Gold Deposit, with all holes intersecting gold mineralization. A total of 51,661 m in 323 holes has been reported to date as part of the ongoing drill program at Enchi, with 98% of holes intersecting gold mineralization.

Diamond Drilling at the Nyam Gold Deposit

NBDD092 to NBDD095A (4 DD holes totalling 1,192 m) were completed at Nyam, targeting high-grade mineralization within the fresh mineral horizon. The goal of this drilling was to continue to expand high-grade mineralization to depth and convert high-grade portions of the existing Inferred Mineral Resource to the Indicated category. The 4 holes focused on testing previously identified high-grade shoots at Nyam to depth. This drilling included some of the deepest holes completed to date at Nyam, reaching a maximum vertical depth of 275 metres. The holes reported in this news release were distributed across 4 separate sections spread along a 410 metre strike length.

Three diamond drill holes totalling 1,018 m (NBDD093 to NBDD095A) targeted extensions to a southern high-grade shoot identified at Nyam. Hole NBDD093 intersected 2.16 g/t Au over 37.0 m from 205 m, including 5.10 g/t Au over 9.0 m from 233 m. This hole filled a gap within prior drilling, targeting conversion of resources from Inferred to Indicated below the current reserve pit. Hole NBDD095A, drilled 60 metres north of NBDD093, also intersected above-reserve grade mineralization with 0.82 g/t Au over 40.0 m from 296 m, including 2.12 g/t Au over 9.0 m from 296 m. Hole NBDD094, collared 40 metres south of NBDD093, intersected 1.51 g/t Au over 21.0 m from 221 m, including 5.37 g/t Au over 5.0 m from 231 m. 

One diamond drill hole totalling 174 m (NBDD092) targeted an apparent gap between two defined high-grade shoots at Nyam. The hole intersected multiple gold mineralized structures including 0.54 g/t Au over 1.8 m from 20.8 m, 0.32 g/t Au over 13.0 m from 94.0 m, and 
 0.52 g/t Au over 6.6 m from 144.4 m. 

These holes were drilled in an area of known mineralization with a goal of continuing to define and grow the future reserve potential at Enchi, including a focus on higher-grade targets. Drilling continues to highlight the potential for future mine plan optimization. Diamond drilling completed at Nyam continues to intersect mineralization above the resource grade and continues to confirm continuity along strike and down dip, extending the principal structures which comprise the Nyam Gold Deposit.

Enchi Work Program

An 80,000 metre drill program is underway at Enchi. The drill program is focused on resource conversion, resource growth and discovery. RC drilling is targeting near-surface mineralization (oxide, transition, and shallow fresh mineralization) focused on resource conversion and continuing to define the potential for reserve and resource growth along strike at existing deposits. Diamond drilling is targeting the high-grade potential at depth. The completed first phase of the drill program was infill drilling for resource conversion, with only the first 28,000 metres of the drill program incorporated into an updated Mineral Resource Estimate announced on March 18, 2026 that formed the basis for a Pre-Feasibility Study ("PFS"). All deposit areas and pre-resource targets at Enchi remain open along strike and at depth, providing for future resource growth across the district-scale property.

Development work continues at Enchi, in support of project advancement, including metallurgical testwork, hydrogeological testing, geotechnical work, and environmental work. A Pre-Feasibility Study was completed in June 2026 (see news release dated June 24, 2026), outlining a base case assessment of developing an open pit, standard milling and carbon-in-leach operation using contract mining and processing 5.5 Mtpa. Recent drilling completed at Enchi has highlighted potential for resource growth, with high-grade encountered at depth and mineralization delineated below the pits that constrain the current Mineral Reserve and Mineral Resource Estimates. Drill results reported in 2026 have not been included in the Mineral Resource Estimate and PFS.

Nyam Gold Deposit

Nyam is one of the four deposits which comprise the Mineral Reserve Estimate and Mineral Resource Estimate at Enchi (Nyam has a Probable Mineral Reserve of 7.2 million tonnes grading 0.76 g/t Au containing 175,000 ounces; an Indicated Mineral Resource of 13.5 million tonnes grading 0.66 g/t Au containing 287,000 ounces; and an Inferred Mineral Resource of 5.5 million tonnes grading 0.68 g/t Au containing 120,000 ounces). Nyam is located 
 15 kilometres east of the town of Enchi, with nearby roads and power and further access provided by a series of drill roads. An airborne geophysical anomaly coincident with the Nyam Gold Deposit defines a complex series of linear high conductivity trends, reflective of the multiple sub-parallel gold-bearing structures. To date, approximately 30% of the gold-in-soil anomaly at Nyam is untested by drilling, with the average vertical depth of all holes drilled to date at Nyam only down to 100 metres.

The Phase 2 program comprises approximately 25,000 metres (m) of diamond drilling designed to increase geological confidence within the current mineral resource estimate and support the conversion of Inferred Mineral Resources to higher-confidence resource categories. All drill holes reported in this release were completed within areas currently classified as Inferred and continue to demonstrate strong grade and geological continuity throughout the deposit.

Significant drill highlights, shown in true widths, include:

• Hole 26EC-131 intersected 14.95 grams per tonne (“g/t”) gold (“Au) over 4.25m;
• Hole 26EC-130 intersected 13.15 g/t Au over 1.50m;
• Hole 26EC-132 intersected 6.81 g/t Au over 1.39m; and
• Hole 26EC-122 intersected 7.03 g/t Au over 1.50m.
• 21,857m (or 46 drill holes) for the Phase 2 Eau Claire program has been completed.

Results are highlighted by drill hole 26EC-131, which intersected 14.95 g/t gold over 4.25 metres true width, approximately 60 metres up-dip from historical hole ER15-572, which previously returned 6.18 g/t gold over 5.05 metres (Figure 2). This intercept confirms the continuity of the high-grade mineralized system and further validates the Company's geological model. The result significantly increases confidence in the continuity of the modeled mineralized zone and is expected to contribute to the conversion of portions of the current Inferred Resource to the Indicated category in a future mineral resource update.

Additional significant intercepts include 13.15 g/t gold over 1.50 metres in hole 26EC-130, 6.81 g/t gold over 1.39 metres in hole 26EC-132, and 7.03 g/t gold over 1.50 metres in hole 26EC-122 (Figure 1).

All drill holes disclosed to date from the Phase 2 program, including those reported in this news release and in the Company’s previous news releases, will be incorporated into the upcoming update of the mineral resource estimate for the Eau Claire Gold Project.

“The primary objective of this drilling campaign is to increase confidence and ounces into the resource model,” commented Tim Clark, CEO of Fury. “Hole 26EC-131 confirms the continuity of high-grade mineralization approximately 60 metres up-dip from historical hole ER15-572 and further validates the geological interpretation of the deposit. These results, in combination with our overall drilling program, continue to support the conversion of portions of the current Inferred Resources to the Indicated category in the next mineral resource update, which will be associated with the pre-feasibility in 2027.”

Table 1: Recent Drill Highlights 

Intercepts were calculated using Au grade*thickness no less than 2 g/t*m width grade no less than 1g/t, maximum consecutive dilution 2m. True thickness was used for intercept calculation.

 Phase 2 drilling is aimed at converting inferred mineral resources into higher-confidence mineral resource categories and expanding the indicated mineral resource. To date, 46 drill holes totalling approximately 21,857 metres have been completed, of which five holes were abandoned, and three holes are in progress. Assay results are currently available for 26 holes totalling 13,374 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.

The intended partnership would provide Swiss Steel Group with access to low-carbon billet and blooms to be further processed for its specialty steel production. An initial supply concept has been developed and technically validated for the American, Canadian, German, Swiss and French facilities, with potential relevance for further Swiss Steel Group Production Assets.  The envisaged partnership would provide Swiss Steel Group with exclusive access to approximately one million tonnes of semi-finished steel products per year from 2030.

“This intended partnership supports an important element of our strategy: focusing our own industrial footprint while securing flexible access to competitive, low-carbon pre-material,” said Frank Koch, CEO of Swiss Steel Group. “It would strengthen our ability to serve our customers with high-quality specialty steels while increasing flexibility across our production network. Together with Canada Nickel Company, we will now work towards translating this concept into a commercially and technically viable long-term partnership.”

"As Canada prepares to host the European Union later this week, this partnership demonstrates how we can translate our shared economic and industrial priorities into tangible commercial opportunities. 
 Canada's mineral resources and competitive, low carbon energy advantages, combined with Swiss Steel's manufacturing expertise and European market access, create an opportunity to build secure, low-carbon supply chains that benefit both economies. Rather than simply exporting energy, Canada Nickel is using this energy for value-added production here at home, strengthening Canada's industrial base while effectively exporting Canada’s natural gas and electricity advantages to support Europe's competitiveness and long-term supply security.  We look forward to working together, along with our existing partners, to unlock European critical minerals funding support for the project.” said Mark Selby, CEO, Canada Nickel Company.

George Pirie, Minister of Northern Economic Development and Growth said that “Northern Ontario continues to demonstrate its strength as a leader in responsibly produced critical minerals and low-carbon industrial development. This is a perfect example of how Northern Ontario transforms energy into value-added products that benefit the world. The proposed partnership between Canada Nickel and Swiss Steel highlights the growing global demand for Ontario’s resources, expertise, and competitive advantages. Initiatives like this reinforce Northern Ontario’s role in building secure supply chains, driving long-term economic growth, and strengthening Canada’s position in global markets.” 

Canada Nickel Company is developing its Crawford Nickel project and intends, through its wholly-owned subsidiary NetZero Metals, to transform the concentrates produced by the mine into a finished nickel product and the nickel-chromium magnetite concentrate into low carbon, and potentially net zero carbon, semi-finished stainless and specialty steel products.
