“Drilling at San Antonio continues to deliver excellent results as we follow up on the previously announced discovery hole, 26-048” says Jonathan Egilo, President & CEO. “We are particularly excited about the Luz del Cobre target due to its proximity to our existing and permitted infrastructure, in addition to the fact that strong oxide gold mineralization is being seen either directly from surface, or at relatively shallow depths. With two of our three diamond drill rigs remaining focused on resource expansion drilling, we are excited to continue showcasing that the scale of San Antonio is growing.”

San Antonio Drill Results

Axo Metals is reporting the results from 33 drillholes, and approximately 3,700 metres of drilling. Today’s results include drilling from the recently announced Luz del Cobre discovery, following up on the highlight hole SOSAP-26-048 which, as previously announced, returned 46.5 metres grading 1.43g/t Au of oxide mineralization directly from surface. The Luz del Cobre target is approximately 750 metres east of the Sapuchi pit-constrained resource. In addition to drilling at the Luz del Cobre target, today’s drilling release contains results in the gap zone between the Luz del Cobre target and the Sapuchi resource, as well as further testing around the peripherals of the Sapuchi deposit.

New results in the Luz del Cobre area continue to be encouraging, including Hole SOSAP-26-069 which returned 48.0 metres of 1.18g/t Au of oxide material directly from surface. Initial drilling in the Luz del Cobre-Sapuchi gap has confirmed at least 450 metres of mineralized strike length. While the Company continues to view the Sapuchi deposit as an excellent starter pit option due to the elevated oxide grades and favourable topography, management notes that Luz del Cobre is only ~1.8km away from the existing plant infrastructure and, due to the area being a past producing open pit, is already connected to the San Antonio infrastructure via haul roads. Thus, the Company is evaluating Luz del Cobre as another compelling option to be mined early in the San Antonio mine life.

Highlights from today’s results include:

• Hole SOSAP-26-069 which reported the first 48.0 metres drilled directly from surface grading 1.18g/t Au. The hole was collared in the Luz del Cobre zone, ~750m east of the Sapuchi resource pit.
• Hole SOSAP-26-083 which assayed 3.94g/t Au over 15.0 metres from only 12 metres down the hole at Luz del Cobre.
• Hole SOSAP-26-053 which was collared along the outer edge of Sapuchi, saw multiple zones including 22.0 metres of 1.62g/t Au, 11.0 metres of 1.72g/t Au and 17.0 metres of 0.94g/t Au.
• Hole SOSAP-26-077 which assayed 0.88g/t Au over 25.8 metres from surface at Luz del Cobre.
• Hole SOSAP-26-080 was collared within the Luz del Cobre-Sapuchi gap zone and returned multiple intercepts from 25.5 metres down the hole to 168 metres. Select separate intervals included 11.0 metres of 1.29g/t Au, 39.6 metres of 0.32g/t Au and 9.0 metres of 0.73g/t Au.
• Hole SOSAP-26-073 which returned two intercepts of 0.81g/t Au over 17.9 metres from only 29 metres down the hole and 0.90g/t Au over 19.9 metres from 55 metres down the hole at the outer edge of the Sapuchi resource.

Figure 2 below shows a cross section that covers approximately 450 metres between the recently discovered Luz del Cobre zone and the existing Sapuchi resource. Hole SOSAP-26-069 from today’s release lies at the base of the former Luz del Cobre historical pit, while hole SOSAP-26-080 returned multiple long intervals of above cut-off mineralization. All drilling in the area is considered resource expansion. 

The Luz del Cobre historical pit was operated from 2011 to 2018 and solely focused on the mining of copper oxide, with 2.8Mt of copper oxide ore mined in that time period. The drilling around Luz del Cobre that is returning strong grades of oxide gold mineralization are not returning material grades of copper, which the Company views as a positive from a metallurgical standpoint.

Drill Plans and RC Waste Dump Drilling Program

There are currently three diamond drill rigs turning at San Antonio. Two are focused on resource expansion drilling around Luz del Cobre and within the Luz del Cobre-Sapuchi gap zone. The third drill rig is positioned at Sapuchi, infilling inferred resource blocks and testing areas to convert waste to ore within the resource pit shell.

The Company is also exploring the gold potential contained within the waste dumps that were built from historical Luz del Cobre operations. From late 2021 to mid-2023, Osisko Gold Group (formerly known as Osisko Development), San Antonio’s operator prior to Axo’s acquisition, mined and processed 1.14Mt of waste dump material grading 0.58g/t Au, recovering 74% via heap leaching, and selling 13,591 gold ounces. Axo has recently completed a ~1,900 metre reverse-circulation (RC) drill program through these waste dump, which has been drilled off to approximately 25 x 25 metre spacings. The Company believes the waste dumps could provide a compelling option for additional resource growth at San Antonio, with any discovered ounces providing an option to potentially expedite production at San Antonio through the processing of waste dumps – at potentially low operating costs and low capital intensity. The waste dumps are situated ~1.8km away from the carbon-in-column plant, and connected via haul roads. The Company expects to receive and disclose these RC drilling results prior to year-end.

La Huerta Update

The Company is announcing that it has elected to terminate the option agreement for the La Gallina concession at its La Huerta copper project in Jalisco, Mexico. Axo Metals continues to retain full ownership of the Juanes concession, which is the concession that holds the overwhelming majority of metres drilled at La Huerta, and all material drilling previously announced and disclosed by the Company. For more details about the La Gallina option agreement, please see our most recent financial statements and MD&A located on SEDAR+.

About Axo Metals

Axo Metals Corp. is a Canadian mineral exploration company engaged in the exploration and development of mineral properties in Mexico. The Company holds two projects. The San Antonio project is located in the state of Sonora, and is in advanced development. Total resources at San Antonio stand at 576koz Au and 1.37moz Ag grading 1.20 g/t Au and 2.9g/t Ag in the Indicated category, with 544koz Au and 1.76moz Ag grading 1.02 g/t Au and 3.3g/t Ag in the Inferred category across all deposit types (oxide, transition and sulphide). Axo’s second project is the La Huerta property, a new copper discovery in Jalisco, Mexico. Initial exploration has yielded high-grade copper both at surface through sampling programs, and at depth through initial drilling. 

Additional information can be found at the Company's website: www.axometals.com.

Procedure, Quality Assurance / Quality Control and Data Verification  

The diamond drill core (HQ size) is geologically logged, photographed and marked for sampling. When the sample lengths are determined, the full drill core is sawn with a diamond blade drill core saw with one half of the drill core being bagged and tagged for assay. The remaining half portion is returned to the drill core trays for storage and/or for metallurgical test work. 

The sealed and tagged drill core sample bags are transported to the ALS Chemex facilities in Querétaro and Zacatecas, Mexico. ALS Chemex crushes the samples and prepares 200-300 gram pulp samples with ninety percent passing Tyler 150 mesh (106 μm). Copper and multi-element analysis is completed using total digestion (Code ME-ICP61 Total Digestion ICP). Over limits greater than 10,000 grams per tonne copper are assayed using Cu-OG62.

Quality assurance and quality control ("QA/QC") procedures monitor the chain-of-custody of the samples and include the systematic insertion and monitoring of appropriate reference materials (certified reference materials, blanks and duplicates) into the sample strings. The results of the assaying of the QA/QC material included in each batch are tracked to ensure the integrity of the assay data.  All results stated in this announcement have passed Axo’s QA/QC protocols.

Grab and trench exploration samples are geologically logged, photographed and marked for sampling and processing in the Company’s on-site laboratory. The sealed and tagged sample bags are transported to the San Antonio On Site Laboratory, in San Antonio de La Huerta, Sonora. Initially, the sample undergoes primary size reduction using a jaw crusher to a nominal particle size of 1/2 inch. The crushed material is subsequently homogenized and split using a riffle splitter. Once completely dry, the sample is pulverized with ninety percent passing 200 mesh. The prepared pulp is subsequently processed by 30g fire assay. The resulting doré bead is then dissolved by acid digestion using aqua regia. The resulting solution is diluted to the appropriate volume and analyzed by atomic absorption spectrometry (AAS) to determine the gold concentration in the sample. Quality assurance and quality control ("QA/QC") procedures monitor the chain-of-custody of the samples and include the systematic insertion and monitoring of appropriate reference materials (certified reference materials, blanks and duplicates) into the sample strings. Results are preliminary and have not yet been verified by an independent, certified commercial laboratory.

Farhad Abasov, Millennial’s Chair, commented: “We are delighted to report another highly encouraging drill result from the Banio Potash Project. The results from drillhole BA-006 are significant for several reasons:

1. BA-006 is the first drillhole to penetrate all known potash cycles in the area, supporting our interpretation that the evaporite sequence and potash mineralization thicken towards the west of the project area.   
2. The drillhole has once again confirmed outstanding potash mineralisation in the form of interbedded carnallitite and halite, including numerous thick carnallitite potash seams totalling approximately 120m of cumulative potash.
3. BA-006 significantly expands the known potash footprint west of the current Mineral Resource Estimate (“MRE”) area, bringing the mineralization closer to the planned processing facility and planned deep-water port sites.
4. Once all drill data have been interpreted and compiled, an updated MRE will be completed, providing 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 located approximately 4km west of BA-001 and was designed to test both the westward continuation of potash mineralization intersected in BA-001 and its southward extension from BA-002 (see Figure 1). Preliminary logging indicates that BA-006 intersected approximately nine evaporite cycles (Cycles II to X), with potash mineralization present in each cycle. Notably, BA-006 intersected Cycles IX and X for the first time at the project, supporting the interpretation that potash mineralization thickens toward the west.

Review of the new BA-006 drill core confirms prominent horizontal bedding dominated by interbedded halite and carnallite (see Photos 1 and 2 below). Preliminary logging estimates the cumulative thickness of the principal carnallitite seams at approximately 120m. Detailed core logging, final interpretation of the evaporite cycles and seam identification, and downhole geophysical logging are ongoing. Core preparation and sampling are expected to be completed over the next several weeks, after which the samples will be submitted to the Saskatchewan Research Council (“SRC”) for analysis.

Photo 2: Red Carnallite-rich core from BA-006- with Carnallite and interbedded Halite at approx. 714.3m to 717.3m depth

The Phase 2 drilling program is designed to test the depth and lateral extent of potash-rich horizons and strengthen the geological understanding of mineralization beyond the boundaries of the 2025 Mineral Resource Estimate (“MRE”). The additional potash horizons identified in BA-006 extend the known mineralized footprint to the west and could possibly in the future contribute further tonnage to the project’s current resource base, which comprises 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 results from BA-006, once results from SRC have been received, may be incorporated into an updated MRE targeted for completion by the end of 2026 as part of the DFS.

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

Drilling is currently ongoing at drill site BA-007, located to the northwest of BA-006 (see Figure 1). In addition, the top section of drillhole BA-008 has also been completed on site and is now ready to commence diamond coring once drillhole BA-007 has been completed. 

The Company continues to advance its Definitive Feasibility Study on the Banio Potash Project, which is being expedited by Micon International, in partnership with Zenito Ltd. and Agapito Associates LLC. ERCOSPLAN Ingenieurgesellschaft Geotechnik und Bergbau mbH will continue to support the project providing geological expertise on the Gabon-Congo Basin and drilling support with geology interpretations for the ongoing drill program.

Eric Chapman, Senior Vice President of Technical Services, commented, “The 2026 infill drilling program returned multiple intersections with gold grades consistent with or higher than the corresponding grades estimated in the block model.” Mr. Chapman added, “We are incorporating the drill results into an updated block model and pit design, targeted for completion by year-end. This work will support a revised LOM plan and an updated Mineral Reserve estimate for Lindero, incorporating both the upgraded gold mineralization and existing Indicated Mineral Resources currently located below the pit.” Mr. Chapman concluded, “This zone remains open at depth.”  

Lindero Mine Drilling highlights

Note: Gold mineralization at Lindero is circular in nature and associated with a porphyry intrusive; therefore, a specific azimuth or dip cannot be defined for reporting estimated true widths.  

The 2026 drill program consisted of 31 diamond drilling (“DD”) holes, totalling 8,534 meters, having been extended from the initially planned 6,000-meter program due to the success from the initial holes. The program was designed with two objectives, firstly to upgrade Inferred Mineral Resources below the current LOM pit design in the south portion of the Lindero Deposit, where higher gold grade mineralization was identified at depth. Secondly, to obtain metallurgical samples to affirm projected recoveries in areas planned for mining in the next two years. The upgrade drilling successfully encountered higher than expected gold mineralization in several holes, such as, LDH-259 that intersected 0.85 g/t Au over 236 meters from surface, including 94 meters averaging 0.66 g/t Au below the current pit design (refer to Figure 1) and LDH-272 that intersected 0.96 g/t Au over 350 meters from surface, including 98 meters averaging 0.91 g/t Au below the pit design (refer to Figure 2). An updated Mineral Resource and Mineral Reserve estimate will be prepared for inclusion in the year-end consolidated report, planned for release in the first quarter of 2027.

Gold mineralization at the Lindero Deposit forms a circular body approximately 600 meters in diameter and extends vertically more than 300 meters below the current topographic surface. The distribution of gold mineralization shows a strong relationship to lithology, stockwork veinlets, and alteration assemblages. Higher gold grades of more than 1 g/t Au, characterized by native, free-milling gold, are commonly associated with sigmoidal quartz, quartz-magnetite-sulfide, biotite-magnetite-chalcopyrite, magnetite-chalcopyrite, and quartz-limonite–hematite stockworks that are strongly associated with K-feldspar alteration. This association is most common in the southern and eastern portions of the deposit, where the highest gold grades occur. Where one or more stockwork types are absent or fracturing is less intense, mineralization tends to be weaker and gold grades lower at approximately 0.4 g/t Au.

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 DD 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 two meters 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 DD samples were transported by commercial transport to ALS Patagonia S.A. preparation laboratory in Mendoza, Argentina. Sample pulps prepared by ALS Patagonia were then transported via commercial courier to ALS’s facility in Lima, Peru. Routine gold analysis using a 30-gram charge and fire assay with an atomic absorption finish was completed for all samples at ALS’s Lima laboratory plus ME-ICP61, analysis of 34 elements four acid ICP-AES. Samples returning assays >10 ppm Au were reanalysed using a 30-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, ALS inserted their own quality control samples.

• Indicated Mineral Resources nearly triple to 8.95 million tonnes grading 1.03% copper and 1.08% nickel, from 3.00 million tonnes grading 0.90% copper and 0.98% nickel in 2024.
• Inferred Mineral Resources increases 63% to 9.48 million tonnes grading 1.21% copper and 1.13% nickel, from 5.83 million tonnes grading 0.90% copper and 1.07% nickel in 2024.
• Drilling drives resource growth and conversion. An additional 42,633 metres in 92 holes since the June 30, 2024 data cut-off supported resource expansion and conversion of approximately 20% of previously Inferred Mineral Resources to Indicated Mineral Resources, strengthening confidence for future mine planning.
• Updated economic and technical inputs. The 2026 Selebi North MRE reflects updated metal price assumptions of US$5.10/lb copper, US$9.10/lb nickel and US$20.00/lb cobalt and incorporates previously reported metallurgical results demonstrating the ability to produce separate, clean copper and nickel concentrates that meet commercial smelter specifications (see news releases dated (September 3, 2025, and October 22, 2025).

New Geological Findings and Interpretations Underway

• Selebi North’s South Limb turns toward Selebi Main at depth, giving the first geological basis for a connection between the two deposits. Previously, the interpreted orientations of the two deposits did not suggest convergence, leaving limited geological support for potential continuity through the interpreted “Hinge Zone”. New drilling establishes the South Limb flattening at depth and turning toward Selebi Main. That geometry is consistent with earlier borehole electromagnetic (“BHEM”) surveys indicating continuity between the deposits. Both copper and nickel grades strengthen down plunge at Selebi North. Together, the structural, geophysical and geochemical evidence supports prioritizing the area between the deposits for further exploration.
• Magnesium-rich rocks point to a possible intrusive keel. Continuing work by Dr. Peter Lightfoot, PhD, P.Geo., consulting geologist to the Company and internationally recognized nickel sulphide specialist and former Chief Geologist at Inco/Vale, has re-interpreted the Selebi intrusive system. Rocks historically logged as “amphibolite” are now recognized as a suite of primary igneous rock types — olivine pyroxenite, pyroxenite, olivine melagabbronorite and gabbronorite — altered to varying degrees. The most magnesium-rich of these, in previously released deep holes SMD-25-202 and SMD-25-204, both down plunge of the Selebi North South Limb toward Selebi Main, retain fresh olivine, the first silicate to crystallize from a magnesian nickel-bearing magma. Rocks of this kind are characteristic of the keel of an intrusion — its deepest, downward-projecting part, where dense magmatic sulphide can accumulate. Together with the structural study underway by TECT Geological Consulting, this work is defining the intrusion’s geometry and the controls on sulphide distribution and is generating targets for further nickel-copper exploration.
• Significant resource growth in 2026 and important geological findings set the stage for further expansion. Drilling at Selebi Main materially extended mineralization, while Selebi North’s South Limb extends down plunge and turns toward Selebi Main. This emerging geological evidence of a potential connection, together with indications of an intrusive keel, points to potential growth opportunities within and between the deposits.

Project Funding Review & Selkirk PEA 

• Project funding review. Earlier this year, the Company engaged National Bank of Canada Capital Markets as financial advisor to evaluate project funding alternatives for its assets, with a focus on minimizing dilution to existing shareholders. The Company is working diligently to conclude its review. There can be no guarantee that this review will result in a transaction.
• Selkirk Technical Study Advances. The Company has engaged DRA Global to complete a Preliminary Economic Assessment (“PEA”) for Selkirk while the Company evaluates a range of strategic options for the asset.

Sean Whiteford, CEO of the Company, commented: “With 8.95 million tonnes Indicated Mineral Resources and 41.95 million tonnes Inferred Mineral Resources, and both deposits still open, we believe Selebi has the potential to become a world-class copper-nickel sulphide project. Growth in our mineral resources at both Selebi North and Selebi Main has exceeded our expectations and demonstrates the value of our investment in drilling and metallurgical work in 2025 and 2026.” 

“At Selebi North, we’ve nearly tripled the Indicated Mineral Resource while increasing copper and nickel grades, and the South Limb is changing direction toward Selebi Main. At Selebi Main, wide-spaced drilling has rapidly expanded tonnage in the newly defined Flexure Zone, delivering higher grades and thicker intersections. Dr. Peter Lightfoot’s interpretation of deep drilling, which is detailed later in the press release, also supports further investigation of a potential intrusive keel, adding another dimension to our exploration targeting.”

“These developments could have positive implications for future mine design and project economics. While we continue to advance the Selebi PEA, we are allowing additional time to better understand the scale and geometry of the expanding resource, inform the placement of critical infrastructure and evaluate alternative restart options. The structural study underway with TECT Geological Consulting will support this work by refining our understanding of the orebody’s geometry and structural controls. The Company will provide further updates on the Selebi PEA, including expected completion timing, as the study advances.”

“We continue to prioritize expenditures across drilling and technical studies, aligning the pace of work with available capital and directing the Company towards the opportunities we believe offer the greatest value creation for shareholders.”

Ultramafic Rocks and Potential Intrusive Keel

Dr. Peter Lightfoot’s examination of the most magnesium-rich rocks in previously released deep holes SMD-25-202 and SMD-25-204 provides further insight into the Selebi intrusive system. Both holes lie down plunge of the Selebi North South Limb, in the direction of Selebi Main.

Rocks historically logged as “amphibolite” are now recognized as a suite of primary igneous rock types, altered to varying degrees to amphibolite. They are interpreted to fall into four main groups: olivine pyroxenite, pyroxenite, olivine melagabbronorite and gabbronorite. A thin section from the most magnesium-rich sample in SMD-25-204 contains fresh olivine, the first silicate to crystallize from a magnesian nickel-bearing magma. Rocks of this kind are characteristic of the keel of an intrusion, its deepest, downward-projecting part, where dense magmatic sulphide can accumulate.

Mafic-ultramafic intrusive rocks relate to nickel sulphide ore in two distinct ways:

• Primary magmatic keel, exemplified by Voisey’s Bay, Labrador. The most primitive rocks, magnesium-rich variable-textured troctolites, are directly linked to the Ovoid and Eastern Deeps orebodies. Sulphide collected where feeder conduits widened or opened into the main chamber. Here, the primitive rocks mark the ore-forming pathway, and tracing them leads toward sulphide.
• Deformation-generated folds and boudins, exemplified by Thompson and Birchtree, Manitoba. Later deformation and high-grade metamorphism broke the original ultramafic intrusions into isolated boudins. Sulphide flows more readily than silicate rock, so it was remobilized to different extents, and where it came to rest differs between deposits. About 90% of Thompson’s ore is now hosted in metasedimentary rocks, with its position controlled by folds and pressure shadows. At Birchtree, by contrast, most of the high-grade mineralization is concentrated at the margins of the ultramafic boudins.

Both processes may have operated in the prospective, approximately 1.5–2 km-long corridor between Selebi North and Selebi Main: primary sulphide concentrated in the keel, then redistributed by folding. Distinguishing their effects will help determine whether exploration follows the magnesium-rich rocks directly or the structures that control them.

1. All tabulated data have been rounded and as a result minor computational errors may occur.
2. Mineral Resources, which are not Mineral Reserves, have no demonstrated economic viability. There is no guarantee that all or any part of the Mineral Resource will be converted into a Mineral Reserve. The estimate of Mineral Resources may be materially affected by geology, environment, permitting, legal title, taxation, socio-political, marketing, or other relevant issues.
3. Mt = Million tonnes, Mlbs = million pounds, CuEq = copper equivalent
4. The 2026 MRE has been prepared in accordance with the CIM Definition Standards (2014) and CIM Best Practice Guidelines (2019) with an effective date of October 16, 2026.
5. Mineral Resources are reported at a cut-off value of US$75/t NSR (Net Smelter Return), defined as received value of final metal recovered minus off-site costs, and a minimum thickness of 1.5 metres. Block model estimates of less than US$75/t NSR are included within the Mineral Resource in areas where it was considered not feasible to mine selectively around them. Areas of the block model were excluded in low grade areas where there is no potential to define a mineable block above US$75/t NSR.
6. Mineral Resources are estimated using long-term prices of US$9.10/lb Ni, US$5.10/lb Cu, US$20.00/lb Co. The same metal prices were used in NSR calculations.

8. Payabilities and off-site treatment and refining costs were derived from an independent marketing study commissioned by NexMetals.
9. Bulk density has been estimated in the block model based on an extensive data set of measurements taken from drillhole cores. The average density is 3.63 t/m³ for the mineralized zone.
10. Mineral Resources are reported using NSR values which assume mining costs of US$47.60/tonne, concentrate processing costs of US$20.00/tonne and G&A of US$5.50/tonne.
11. Areas depleted or sterilized by mining were removed from the mineral resource.
12. There are no Mineral Reserves.
13. Copper equivalent is calculated using the formula CuEq =(Cu%*96.4+Ni%*87.0+Co%*132.7)/96.4.

Mineral Resource Data and Quality Control

The historical sampling data collected by the previous owner and operator, BCL Limited (“BCL”) included Ni and Cu assays. The historical data was verified by NexMetals through drilling of new underground holes and visual inspection of exposed mineralization in underground workings. The data compared within reasonable limits given the variability of the mineralization.

The geological database used in the Selebi North MRE included 175 NexMetals drillholes, completed in 2023, 2024 and 2025, drilled at various inclinations and directions from underground workings. BCL drilled numerous horizontal resource definition holes as horizontal fans on each sublevel. Channel samples were cut perpendicularly across the mineralization exposed in the 10 m to 15 m vertically spaced sill drives at 10 m intervals along strike using a saw with rotating diamond impregnated blades. In many cases, diamond drilling extended the channel sample intercept into either or both sidewalls where the mineralization was not fully exposed in the sill drive. MSA examined the BCL data in and immediately surrounding the unmined areas for spatial consistency with the underground workings and included the validated data in the estimation data. Historical surface drillholes were not used in the estimate due to discrepancies in the position of mineralized intercepts relative to underground acquired data. Given the voluminous underground drilling and channel sampling database, the exclusion of the BCL surface drillhole data is not significant to the estimate.

The BCL assays were completed at the BCL Phikwe Laboratory. At the time of preparation and analysis, the BCL-owned laboratory was not independent of the operator and accredited only for high grade matte analyses, but not for exploration grade analyses. Ni and Cu were analysed by flame atomic absorption spectrometry. Relative density measurements were obtained by water immersion method.

The NexMetals drill core was logged, photographed and marked for sampling in nominal lengths of one metre. The core samples were cut in half longitudinally using a rotating diamond saw. The core samples were given a unique sample reference number, bagged and despatched to ALS Laboratories Ltd. in Johannesburg, South Africa for analysis (SANAS Accredited Testing Laboratory, No. T0387). Samples were analysed for Ni, Cu, and Co using a peroxide fusion preparation and inductively coupled plasma atomic emission spectrometry (ICP-AES) finish (ME-ICP81). Analyses for Pt, Pd, and Au were by fire assay (30 g nominal sample weight) with an ICP-AES finish (PGMICP23), also by ALS. Ag was analysed using a 4-acid digest and ICP-AES finish (ME-ICP61). Specific gravity measurements were also completed by ALS on pulps of selected samples.

The NexMetals drilling was subjected to a comprehensive programme of quality assurance and quality control by NexMetals, independent of the laboratories’ own QAQC measures, including certified reference materials (5%), blank samples (5%), coarse duplicate samples (5%) and pulp duplicate samples (5%). The Qualified Person, Mr. J.C. Witley (BSc Hons, MSc (Eng.)), is satisfied that the assay results are of sufficient accuracy and precision for use in Mineral Resource estimation.

Mineral Resource Estimate

The 2026 Selebi North MRE was completed by The MSA Group in Johannesburg, South Africa.

The Mineral Resource was estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Best Practice Guidelines and is reported in accordance with the 2014 CIM Definition Standards, which have been incorporated by reference into National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

The deposit can be described as a metamorphosed magmatic nickel-copper sulphide deposit. Mineralization is hosted with a folded amphibolite unit that is structurally complex and comprises two main fold structures that are contiguous forming two antiformal structures separated by a synformal structure. The limbs and the fold closures are mineralized and define three main zones with differing geological characteristics known as the South Limb, N2 and N3. The synformal area between the N2 and N3 and towards the southern part of the South Limb tend to have more variable mineralization The mineralization plunges approximately 40° to 45° towards the west to west-southwest, although a change in the plunge direction towards the southwest is interpreted in the deeper areas. The northern limbs to each fold structure are subvertical, whereas the southern limbs tend to be more moderately dipping and variable at an average of approximately 40°to the southeast. The South Limb and South Limb-N2 fold closure generally hosts the thickest intervals of mineralization, whereas the N3 Limb hosts the highest grades. Mineralization can reach thicknesses of up to 30 m in the fold closure areas and can narrow to 10’s of cm in the N3 and pinch out locally. Mineralization at Selebi North comprises massive, semi-massive and disseminated sulphides contained within a unit of amphibolite that is surrounded by undifferentiated quartzo-feldspathic and mafic gneisses. In the wider portions of the deposit a distinct schistose amphibolite unit occurs which generally forms the footwall to the potentially economic mineralization, however locally mineralization can extend to within it. Massive sulphide tends to be preferentially developed near the hangingwall contact with the gneiss.

NexMetals drilling intersected nickel-copper sulphides at depths of up to approximately 1,550 m below surface. Stoping has depleted the Mineral Resource from near surface to between approximately 850 m and 900 m below surface.

Cobalt and silver occur within the nickel-copper sulphide mineralization, with sufficient cobalt data to include in the 2026 MRE; however, silver assays are not available over much of the Mineral Resource extent and have not been included in the 2026 Selebi North MRE. Minor concentrations of platinum and palladium occur within the nickel-copper sulphide mineralization for which economic potential has not been established and, similarly to silver, platinum and palladium assays do not cover the full extent of the Mineral Resource. Sulphide mineralogy is primarily pyrrhotite, chalcopyrite and pentlandite.

All recent exploration at the project, since the closure of the mine, was completed by NexMetals between 2022 and 2026. All prior exploration work of relevance to the 2026 Selebi North MRE was completed by the previous operator, BCL, up until 2016, this being the underground drilling and channel sampling that exist within the top 50 m of the mineral resource and inform less than 10% of the Mineral Resource Estimate. The drilling completed since the 2024 MRE allowed for refinement of the previous interpretation and extension to the previously defined resource area. No additional exploration data have been collected since the last assays were received by NexMetals on 26 April 2026.

Geological modelling was undertaken in Leapfrog Geo utilising implicit modelling. Mineralized intercepts were defined in the drillhole and channel sample data based on thickness, lithology and grade. Intercepts were selected based on an approximate threshold Net Smelter Return (NSR) value of US$70/t using nickel, copper and cobalt grades, while ensuring geological continuity between closely spaced intercepts. Given the strong association of the higher grade mineralisation with the hangingwall contact of the amphibolite with the enclosing gneiss this was used as the preferred hangingwall contact during modelling to ensure geological continuity. A minimum thickness of 1.5 metres was used to allow for a potential minimum mining width, and in some cases dilution outside the mineralized vein was included.

Variography was completed using Datamine Supervisor software. Ellipsoids were orientated in the plane of mineralization with anisotropy along the mineralization plunge. Nickel, copper, and cobalt grades and density were interpolated into a non-rotated block model with a parent cell size of 5 mX by 5 mY by 5 mRL using ordinary kriging. The Datamine process of “Dynamic Anisotropy” was used to modify the search ellipse to changes in the mineralization orientation. Volumes representing mined voids were removed and NSR was then calculated for each block model cell using the estimated grades, metal prices, recoveries, off-site costs and payabilities. The Mineral Resource was classified into the Indicated and Inferred categories, taking into account data quality, geological modelling uncertainty, drillhole spacing, drillhole intersection angle and kriging outputs. The majority of the Inferred Mineral Resource is informed by drillholes with an approximate spacing of 100 metres and the majority of the Indicated Mineral Resource is informed by drillholes with an approximate spacing of 50 metres or significantly less close to the mined areas. The Mineral Resource extent was extrapolated a maximum of 50 metres along strike taking into account the mineralization trends and surrounding data.

The Mineral Resource was reported using a NSR value above US$75/t and a minimum thickness of 1.5 metres. Block model estimates of less than US$75/t NSR are included within the Mineral Resource in areas where it was considered not feasible to mine selectively around them. Areas of the block model were excluded in low grade areas where there is no potential to define a mineable block above US$75/t NSR. Using concentrate processing costs of US$20.00/tonne, G&A of US$5.50/tonne, mining costs of US$47.60/tonne and royalties of 3% for base metals, the Mineral Resource satisfies cut-off grade criteria and the QP considers that reasonable prospects for eventual economic extraction (RPEEE) for the Mineral Resource have been demonstrated.

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. There is no certainty that any Mineral Resources will be converted into Mineral Reserves. The quantity and grade of reported Inferred Mineral Resources in the 2026 MRE are uncertain in nature, there has been insufficient exploration to define these Inferred Mineral Resources as an Indicated or Measured Mineral Resource, and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured Mineral Resource category.

Inflation Keeps the Fed and Gold on the Move

Dear Readers,

Following the release of the September data on October 14, U.S. monetary policy once again took center stage. According to the U.S. Bureau of Labor Statistics, consumer prices rose by 3.7 percent year-over-year. Persistent inflation is increasing pressure on the Federal Reserve to carefully weigh its future interest rate policy.

In September, the seasonally adjusted Consumer Price Index rose by 0.6 percent compared with August; gasoline prices rose by 9.1 percent. The rise in gasoline prices accounted for more than half of the total monthly increase. In addition to inflation, real interest rates, the dollar’s performance, and geopolitical risks are key factors influencing gold prices. Fed Chairman Kevin Warsh also emphasized in his August 28 speech that the central bank must assess inflation trends rather than individual data points. 

GoldMining Continues Development of La Mina and Crucero

GoldMining Inc. - https://www.commodity-tv.com/ondemand/companies/profil/goldmining-inc/ - develops gold and copper projects in North and South America. For its wholly-owned Crucero project in Peru, the updated resource estimate now includes antimony. 

For La Mina in Colombia, GoldMining published an updated preliminary economic assessment in April: It calculates a post-tax net present value of approximately one billion U.S. dollars at a five percent discount rate. The model uses a gold price of 3,500 U.S. dollars per ounce.

Discovery Mining Reports Cordero Permits

Discovery Mining Ltd., - https://www.commodity-tv.com/ondemand/companies/profil/discovery-silver-corp/ - formerly Discovery Silver, produces gold at the Porcupine Complex in Ontario. The company forecasts 260,000 to 300,000 ounces of gold for 2026. In contrast, the company’s Cordero property in Mexico is still under development and is not a producing silver operation.

On October 5, Discovery announced that it had received the environmental impact permit and the land-use change permit for Cordero from SEMARNAT. According to the company, this completes the federal environmental permitting process, but does not automatically fulfill every other requirement for mine construction. Extensive exploration drilling was also planned for 2026.

Conclusion: GoldMining and Discovery Mining on the Verge of Milestones

Inflation trends keep gold in the spotlight as a diversification opportunity, though they do not guarantee short-term price gains; at the same time, higher real interest rates can weigh on the price of gold and make financing mining projects more expensive. For GoldMining, the focus is on further project studies and exploration, while for Discovery, it is on Porcupine production and the development of Cordero.

Dear Readers,

A reliable energy supply is crucial for long-duration space missions. Radioisotope power generators produce electricity from decay heat without requiring sunlight. The Voyager probes, launched in 1977, still use such systems today. Unlike nuclear reactors, they do not rely on a controlled nuclear fission chain reaction.

As the distance from the Sun increases, the available radiant power decreases. Nuclear systems can therefore offer advantages for missions far from the Sun, but must be evaluated in terms of mass, power, safety, and operational lif. It cannot be concluded from this that they generally have a weight advantage over solar systems.

Historically, nuclear fission reactors have also been tested in space, such as the American SNAP-10A in 1965 and later Soviet systems. Reactor concepts are being investigated for future lunar stations; nuclear-thermal rocket propulsion systems remain under development. There is no evidence of a direct supply relationship between the uranium companies presented here and the space industry.

Uranium Energy Increases Production

Uranium Energy Corp. - https://www.commodity-tv.com/ondemand/companies/profil/uranium-energy-corp/ - is expanding its U.S. uranium production using the in-situ recovery process, in which uranium is extracted from underground using solutions. In the fourth quarter of the fiscal year ended July 31, 2026, 82,744 pounds of uranium material were sourced from Christensen Ranch and Burke Hollow.

Compared to the previous quarter, the reported volume increased by 157 percent; the company’s proprietary metric for total costs per pound fell by 33 percent to $36.54. UEC reported $753 million in liquid assets, net of debt, at the end of the fiscal year. A National Security Advisory Council, established in October, is tasked with providing strategic guidance on planned uranium conversion capacities.

IsoEnergy Expands Exploration

IsoEnergy Ltd. - https://www.commodity-tv.com/ondemand/companies/profil/isoenergy-ltd/ - develops uranium projects in Canada and the U.S. Its Larocque East project in the Athabasca Basin hosts the Hurricane deposit, which, according to the company, contains 48.6 million pounds of indicated U₃O₈ resources at a grade of 34.5 percent. 

In the summer of 2026, IsoEnergy completed 10,159 meters of drilling across 26 holes. Drill hole LE26-250 yielded 43,160 radioactive count events per second over 0.5 meters; this borehole length does not represent a confirmed true thickness, and the measured value does not represent a laboratory-determined uranium content.

In August, a completed transaction resulted in the formation of DISA Uranium Corporation, in which IsoEnergy holds an interest.

Conclusion: Uranium Energy and IsoEnergy on the Verge of Milestones

The space industry highlights the technical breadth of nuclear applications, while uranium companies depend on independent industrial demand trends. For UEC, production expansion and conversion plans are key; for IsoEnergy, it’s analyses and further project progress. Permits, financing, and implementation remain critical. Uranium stocks are subject to significant operational, commodity price, and loss risks.

Dear Readers,

On October 7, Indonesian Minister Bahlil Lahadalia stated that the government is considering a moratorium on new nickel processing plants that produce only intermediate products. The measure is currently an option, not a general production ban. Existing plants would not be automatically affected by this.

Indonesia dominates global nickel production and has built up significant capacity for nickel pig iron and ferronickel. A limit on new construction could slow future supply growth. However, demand, inventories, and existing production remain the key determinants of price trends.

For cobalt, the Democratic Republic of the Congo is already relying on export quotas. On October 16, 2025, this system replaced a previously imposed export ban. A maximum of 96,600 metric tons is planned for both 2026 and 2027. S&P Global therefore forecast potential market deficits; these remain uncertain.

Canada Nickel Moves Forward with Crawford

Canada Nickel - https://www.commodity-tv.com/ondemand/companies/profil/canada-nickel-company-inc/ - is developing the Crawford nickel project in Ontario, which also contains cobalt. On July 31, the company announced a provincial approval decision in the environmental review process. This is an important step, but it does not replace all permits that may be required for construction and operation.

In September, Canada Nickel reported on the selection of suppliers for its planned mining fleet. The company is also working with GeoRedox on a geological hydrogen program. Resource estimates were reported for Nesbitt and Deloro; Reid provided additional exploration results. Financing and project implementation remain critical.

NexMetals Reports 72 Percent Increase in Resource Tonnage

NexMetals Mining - https://www.commodity-tv.com/ondemand/companies/profil/nexmetals-mining-corp/ - is developing the formerly producing Selebi and Selkirk projects in Botswana. On October 1, the company reported inferred resources for Selebi Main of 32.47 million metric tons containing 1.53 percent copper and approximately 0.98 percent nickel. The resource tonnage increased by 72 percent compared to 2024.

According to the company, the estimate includes approximately 495,400 metric tons of copper and 316,800 metric tons of nickel. Selebi North was not yet included in this estimate; a separate estimate was being prepared. Resources are not reserves; their economic mineability has therefore not been proven. Selkirk is also part of the project portfolio.

Conclusion: Canada Nickel and NexMetals on the Verge of Milestones

Disruptions to nickel and cobalt supply chains could provide a tailwind for Western projects. Canada Nickel is working on the development of Crawford, while NexMetals is focused on expanding its resource base. Financing, permits, and implementation remain critical. Mining stocks are subject to significant commodity price, project, and dilution risks.

++ Copper: Supply and Demand in Tension ++

Dear Readers,

In the copper market, production risks are clashing with growing structural demand. Power grids, electric mobility, and data centers all require the metal; at the same time, mine outages and extended project timelines can disrupt supply. Short-term demand, however, remains dependent on economic conditions and industrial production. Inventory movements and uncertainty regarding trade barriers can also trigger significant price fluctuations.

On August 21, J.P. Morgan Global Research forecast a price of $14,800 per metric ton of copper for the fourth quarter of 2026. The bank cited, among other factors, tight mine supply, sulfur shortages, and looming U.S. tariffs as drivers. The forecast does not constitute a guaranteed price trend.

Sulfur is needed to produce sulfuric acid, which is used in certain copper extraction processes. Labor disputes in Chile and the continued shutdown of the Cobre Panamá mine also highlight supply risks. New production capacity is not available in the short term; at the same time, a weaker economy and increased production could put downward pressure on prices.

Mogotes Metals Plans Extensive Drilling

Mogotes Metals - https://www.commodity-tv.com/ondemand/companies/profil/mogotes-metals-inc/ - is exploring the Filo Sur copper-gold-silver project in the Vicuña District, which straddles the Argentina-Chile border. At the Albor target area, drill hole FS_DDH_016 returned 180 meters of 0.98 percent copper equivalent starting at a depth of 108 meters, according to a July 9 announcement. This refers to the drill hole length, not confirmed true thickness.

For Filo Sur, Mogotes plans to drill up to 20,000 meters during the 2026–27 season, subject to weather and access conditions. At Beskauga in Kazakhstan, up to 50,000 meters are planned; the project is subject to an acquisition option. At Copper Cliff in Montana, 8,000 to 9,000 planned meters are still pending permits.

U.S. GoldMining Completes Drilling Program

U.S. GoldMining - https://www.commodity-tv.com/ondemand/companies/profil/mogotes-metals-inc/ - holds full ownership of the Whistler Gold-Copper Project in Alaska, according to the company’s own information. The project area covers approximately 217.5 square kilometers. A preliminary economic assessment (PEA) outlines a potential development scenario; mineral resources are not reserves, and their economic viability has therefore not been proven.

On September 22, the company announced the completion of 7,493 meters of drilling in 17 core holes at ten target areas. The program was completed on schedule and within budget. Laboratory results were expected in the coming weeks and by the end of the year; further technical work remains necessary. It is currently unclear whether additional economically viable deposits can be proven.

Conclusion: Mogotes Metals and U.S. GoldMining Approach Milestones

Long-term demand for copper provides a favorable market environment for both exploration companies. For Mogotes, the focus is on upcoming drilling and permits; for U.S. GoldMining, it is on new assay results and the further development of Whistler. Financing and successful execution remain critical.

Dear Readers,

The recovery in the gold price at the end of the week through October 9 was followed by a cautiously optimistic sentiment among professional market observers. The Kitco survey showed that seven out of 14 analysts expected prices to rise in the coming week; two anticipated declines, and five were neutral or undecided.

Among the 206 participants in the online survey, 93 and 45 percent, respectively, expected gold prices to rise. Another 77 anticipated falling prices, while 36 expected sideways movement. The survey captures opinions for a short-term forecast horizon and is neither a representative investor study nor a reliable long-term price forecast.

Rich Checkan of Asset Strategies International considered a Federal Reserve interest rate hike in October unlikely at the time of the survey. Adrian Day expected volatile prices until a possible end to the war in Iran. Inflation data and bond yields remain key influencing factors.

Osisko Gold Group Prepares for Cariboo

Osisko Gold Group - https://www.commodity-tv.com/ondemand/companies/profil/osisko-gold-group-inc/ - is developing the Cariboo gold project in British Columbia, which it owns entirely and for which it has received all necessary approvals. The updated corporate timeline calls for construction to begin in August 2026, with the first gold pour in the first quarter of 2029 and commercial production in the second half of 2029. 

Recent infill drilling in the Lowhee Zone returned, among other results, 7.28 g/t gold over 16.15 meters. The results support further geological evaluation but do not, on their own, constitute proven resource growth. Financing and construction progress remain critical.

Southern Cross Gold Develops Sunday Creek

Southern Cross Gold Consolidated - https://www.commodity-tv.com/ondemand/companies/profil/southern-cross-gold-consolidated-ltd/ - is developing the Sunday Creek gold-antimony project in the Australian state of Victoria. According to the company, antimony accounts for about one-fifth of the estimated in-situ metal value. A 200,000-meter drilling program is intended to support further exploration.

In September 2026, the application for a mining license for Sunday Creek was accepted for processing. According to company information at , 435.5 meters of the exploration tunnel had been excavated by the end of September; completion was postponed to January 2027. 

Conclusion: Osisko Gold Group and Southern Cross Gold Approach Milestones

The market environment continues to focus on gold projects, while interest rates and geopolitical events may cause volatility. Osisko is set to begin construction and production preparations, while Southern Cross is focused on exploration and permitting. Financing and execution remain critical.

1. “Silver equivalent production” include gold ounces, copper tons and zinc tons produced and converted to a silver equivalent based on a ratio of the average market metal price for each period.  The gold:silver ratio for each of the periods presented were:   2022 – 82, 2023 – 83, 2024 – 88, 2025 – 90, 2026 – 66.  The copper:silver ratio for the periods presented were: 2022 – 410, 2023 – 373, 2024 – 345, 2025 – 296, 2026 – 188.  The zinc:silver ratios were: 2024 – 99, 2025 – 85, 2026 – 53.

Silver production increased by 18% in 2026 compared to 2025, while gold decreased by 5% over the same period.   SEO produced in 2026 decreased by 14%, which was significantly impacted by the increase in silver price relative to gold during the year, resulting in a decrease from 90 to 66 in the gold:silver ratio.  For comparative purposes, applying the 2025 silver equivalency ratios for gold, copper, and zinc to the 2026 production figures would have resulted in 2,184,844 SEO – a 2% increase from 2025 to 2026.

Table 2: Quarterly Production Summary

1. “Silver equivalent production” include gold ounces, copper tonnes and zinc tonnes produced and converted to a silver equivalent based on a ratio of the average market metal price for each period.  The gold:silver ratio for each of the periods presented were:  Jun 2025 – 98, Sep 2025 – 88, Dec 2025 – 76, Mar 2026 – 58, Jun 2026 – 62, Sep 2026 – 68.  The copper:silver ratios were: Jun 2025 – 311, Sep 2025 – 251, Dec 2025 – 204, Mar 2026 – 152, Jun 2026 – 181, Sep 2026 – 225.

 Separately, the Company is pleased to confirm it has been named a preferred recipient under the Victorian Government's Advancing Antimony Grants program. The Victorian Government announced yesterday that SXGC and Ballarat-based Gekko Systems will share more than A$750,000 through the program, to fund studies into antimony processing options and supply chains (New Grants to Back Antimony Processing in Victoria, 14 October 2026).

Michael Hudson, President and CEO, states: “Sunday Creek is a high-grade gold discovery with a meaningful antimony component, which contributes approximately 15% to 17% of the project's in situ recoverable value. The Carroll Labor Government's election commitment is a practical step towards processing that antimony into metal here in Victoria. Sovereign infrastructure requires political will to actually build, and we thank Premier Carroll and Minister Symes for their support of domestic processing. The Advancing Antimony grant funds the test work needed to assess turning potential future Sunday Creek concentrates into antimony metal for Australian and allied supply chains. We look forward to continuing to work with the State Government including Resources Victoria and the Commonwealth Government in their support of this crucial development in Australia’s onshore supply chain.” 

The Company notes that the A$20 million commitment is an election commitment of the Victorian Labor Party, conditional on its re-election at the Victorian State election on 28 November 2026, and on the terms of any future funding arrangements. The Company will continue to engage with government on the development of antimony processing in Victoria.

Bringing antimony processing onshore

Antimony concentrate produced in Victoria is currently shipped overseas for processing. Antimony is listed as a critical mineral by Australia, the United States, Canada, the European Union and Japan, and is used in defence applications, solar panel glass, batteries, flame retardants and electric steel for drones and electric vehicles.

The Sunday Creek Gold-Antimony Project contains antimony mineralisation associated with high-grade gold. The Company is studying the production of antimony metal in Victoria through an antimony metallisation facility, which would take concentrate from Sunday Creek and other Australian producers. 

The Advancing Antimony grant will contribute to pilot-scale metallisation test work on Sunday Creek concentrate. This includes confirming antimony and gold recoveries, testing antimony metal product quality, and characterising process residues for environmental permitting. It also funds updated flowsheet and balance-of-plant engineering for the proposed facility.

Announcing the grants, Minister for Energy and Resources Jaclyn Symes said: “We’re backing Southern Cross Gold and Gekko Systems to build the case for local antimony processing and bring new investment to regional Victoria.”

About Sunday Creek 

The Sunday Creek epizonal-style gold project is located 60 km north of Melbourne (Figure 1) within 16,900 hectares (“Ha”) of granted exploration tenements. SXGC is also the freehold landholder of 2,296 Ha that form the key portion of land in and around the main drilled area at the Sunday Creek Project.  The Company applied for its first mining licence, MIN009040, in September 2026.

Further Information 

Further discussion and analysis of the Sunday Creek project is available through the interactive Vrify 3D animations, presentations and videos available on the SXGC website. Interviews with President and CEO Michael Hudson can be viewed at www.southerncrossgold.com. 

Critical Metal Epizonal Gold-Antimony Deposits

Sunday Creek (Figure 1) 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 SXGC's projects. Antimony alloys with lead and tin, resulting 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% of the in situ recoverable value of Sunday Creek, based on the AuEq ratio of 2.39 set out below.

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 106 composite intersections exceeding 100 g/t Au from 146.4 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 Gold's 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, 2,296 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 1 jurisdiction, delivering milestone by milestone.

NI 43-101 and JORC Qualified/Competent Person Statement

The scientific and technical information in this news release has been prepared, reviewed, verified and approved by, or prepared under the supervision of, Mr Kenneth Bush, Head of Exploration of Southern Cross Gold Consolidated Ltd. Mr Bush is a Member of the Australian Institute of Geoscientists and a Registered Professional Geologist in the fields of Mining and Exploration (#10315). He is a Qualified Person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”). He has sufficient experience relevant to the style of mineralisation and type of deposit under consideration, and to the activities undertaken, to qualify as a Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the “JORC Code”). Mr Bush holds shares (less than 1%) in the Company. Mr Bush consents to the inclusion in this news release of the matters based on his information in the form and context in which it appears.

Gold Equivalent Calculation

SXGC considers that both gold and antimony 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 for processing during WW1 to the Costerfield mine, located 54 km to the northwest of the project. The Costerfield mine corridor, now owned by Alkane Resources Limited (previously Mandalay Resources Ltd.), contains two million ounces of equivalent gold (Mandalay Resources Q3 2021 Results). In 2020 it was the sixth highest-grade underground mine globally and a top 5 global producer of antimony.

SXGC considers it appropriate to adopt the same gold equivalent variables as Mandalay Resources Ltd (now Alkane Resources Limited) used in its 2024 End of Year Mineral Reserves and Resources Press Release, dated 20 February 2025. That formula was calculated using Costerfield’s 2024 production costs, 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. It 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 mineralisation at Costerfield, SXGC considers that AuEq = Au (g/t) + 2.39 × Sb (%) is appropriate to use for the initial exploration targeting of gold-antimony mineralisation at Sunday Creek.

+++ Nuclear Power Contracts Strengthen the Outlook for Uranium +++

Dear Readers,

On October 6, 2026, Google and Constellation agreed to a 20-year power purchase agreement. The agreement with the U.S. power plant operator is intended to enable 890 megawatts of additional nuclear power capacity through capacity upgrades at existing U.S. facilities. Constellation plans to invest more than 4.3 billion U.S. dollars for this purpose.

The spot price published by Cameco stood at $89.63 per pound of U₃O₈ on September 30, compared to $48.38 four years earlier: an increase of 85.3 percent. Interim declines highlight the price’s volatility. Long-term power purchase agreements can support investments in additional nuclear power capacity.

According to the U.S. Energy Information Administration (EIA), 93 percent of uranium supplies in 2025 were of foreign origin, up from 92 percent the previous year. Canada, Kazakhstan, and Australia topped the list of sources. The data reflects volumes purchased by U.S. nuclear power plant operators, not direct reactor consumption. This underscores the importance of reliable supply chains.

Premier American Uranium Moves Forward with Cebolleta

Premier American Uranium - https://www.commodity-tv.com/ondemand/companies/profil/premier-american-uranium-inc/ - develops U.S. uranium projects. Regarding the Cebolleta project in New Mexico, the company reported on July 13 that test drilling had been completed. Metallurgical tests are intended to optimize heap leaching and support an update to the preliminary economic assessment planned for 2027.

At Kaycee in Wyoming, Premier reported on October 7 a grade of 0.064 percent eU₃O₈ over 10 feet in hole WD26-012, between 859.5 and 869.5 feet. The grade is derived radiometrically. According to the company, the hole length approximately matches or slightly exceeds the true thickness.

Uranium Royalty Expands Its Portfolio

Uranium Royalty - https://www.commodity-tv.com/ondemand/companies/profil/uranium-royalty-corp/ - completed the Sweetwater transaction on July 27. Approximately 92 percent of the interests in the relevant Sweetwater companies were consolidated under the new U.S. parent company, Uranium Royalty Corp., with the existing company. Trona royalties, as well as land and mineral rights, now complement the uranium portfolio. “New URC” was the parent company’s abbreviated name.

For the first fiscal quarter of 2027, which ended on July 31, Uranium Royalty reported a record net profit of $16.3 million. In addition to uranium sales, valuation and currency gains, as well as offsetting transaction costs, influenced the result. Royalty rights to McArthur River and Cigar Lake complement the portfolio; they do not guarantee ongoing payments.

Conclusion: Premier American Uranium and Uranium Royalty on the Verge of Milestones

Long-term nuclear power contracts support the outlook for the uranium market. For Premier, the focus is on metallurgical testing and further drilling; for Uranium Royalty, it is on developing its expanded portfolio. Financing and execution remain critical. Uranium stocks carry additional corporate risks and, despite positive industry signals, offer no guarantee of price stability.

Potash Demand Supports New Projects

Dear Readers,

Over the long term, efficient nutrient supply matters: according to the FAO, cropland per capita declined by about 20% between 2001 and 2024, while total cropland increased. In addition, potash has been on the final U.S. List of Critical Minerals since November 2025. According to the USGS, potash is used in most fertilizers.

Millennial Potash Continues Developing Banio

Millennial Potash - https://www.commodity-tv.com/ondemand/companies/profil/millennial-potash-corp/ - has held an indirect 80% interest in the Banio potash project in Gabon since April 2026. The exploration licenses cover approximately 1,500 square kilometers, including coastal areas. Access to the Atlantic opens up logistical opportunities for future exports, for example to Brazil.

The preliminary economic assessment (PEA) of April 2024 modeled operating costs of US$61 per metric ton of granular potassium chloride at an annual production of 800,000 metric tons via solution mining.

U.S. Support Accompanies the Studies

The U.S. International Development Finance Corporation (DFC) has committed up to US$3 million in study support. On April 15, 2026, Millennial stated that it was sufficiently funded for the planned study programs. According to company planning, the feasibility study is to be completed by the end of 2026, and according to the latest information, the environmental and social impact assessment by early 2027. Secured financing for mine construction is not evidenced by this.

On August 26, 2026, Millennial reported that drill hole BA-006 expanded the known potash mineralization to the southwest, closer to the coast and to the planned port site. The information is based on preliminary core logging; laboratory analyses are still pending. An updated resource estimate is to be completed by the end of 2026 and incorporated into the feasibility study. Environmental impacts, permits, and technical implementation remain to be assessed as the project progresses.

Conclusion: Millennial Potash Approaching Milestones

The demand described by Nutrien generally supports the development of new potash projects. At Millennial Potash, the focus is on completing the studies and further defining the infrastructure. This could set the stage for an interesting and price-sensitive news flow even before the end of the year. Stay on top of things.

Mr. D’Agostino and Admiral Caldwell will serve as Co-Chairs of the Council. The Council includes two former Admirals and two former heads of the National Nuclear Security Administration (the “NNSA”), the agency that recently issued a request for information seeking a long-term domestic supply of unobligated U.S.-origin uranium and conversion services.

Amir Adnani, President and CEO, stated: 

“Defense demand for American nuclear fuel is growing quickly, with the Army’s Janus Program bringing microreactors to U.S. military bases and the Navy’s expanding fleet continuing to run on nuclear power. We are honored to have such esteemed national security leaders supporting the UEC team as we build an American supply chain, from mine to conversion, for critical defense missions.”

The Honorable Tom D’Agostino, former Administrator of the NNSA and Co-Chair of UEC’s National Security Advisory Council, stated: 

“The NNSA’s mission depends on a reliable, long-term supply of unobligated U.S.-origin uranium, mined and converted using American technology. UEC is uniquely positioned to deliver that supply, with the largest U.S. uranium resource base and a clear path into domestic conversion. I look forward to helping the Company serve this vital national mission.”

Admiral James F. Caldwell, former Director of the Naval Nuclear Propulsion Program and Co-Chair of UEC’s National Security Advisory Council, stated: 

“For more than 75 years, naval nuclear power has provided the Navy’s submarines and aircraft carriers with an incredible warfighting advantage, and that mission depends on secure, reliable, domestic fuel supply. As the Navy embarks on a future generation of nuclear-powered submarines, aircraft carriers, and potentially other warships, and as nuclear energy expands across the Department of War, a strong American uranium and conversion industry is essential to mission readiness. I am proud to help UEC build it.”

The Honorable Spencer Abraham, former U.S. Secretary of Energy and Chairman of UEC’s Board of Directors, added:

“As Secretary of Energy, I saw firsthand how America’s nuclear deterrent, naval propulsion and civilian nuclear power all depend on secure domestic fuel supply. Today, domestic conversion is the essential link between American uranium and the billions of dollars being invested in new U.S. enrichment capacity. The leaders on this Council ran the very programs that rely on that supply, and their guidance will be invaluable as the nation expands it.”

The Honorable Tom D’Agostino served more than 36 years in government. As Under Secretary of Energy for Nuclear Security and Administrator of the NNSA from 2007 to 2013, under Presidents George W. Bush and Barack Obama, he was responsible for the safety, security and effectiveness of the U.S. nuclear weapons stockpile, and he remains the longest-serving Administrator in the agency’s history. Earlier, as Deputy Administrator for Defense Programs, he directed the Stockpile Stewardship Program across the national laboratories and production plants. As a former naval submarine officer, he also supported the SEAWOLF submarine propulsion program and was instrumental in initiating the Department of Energy’s (“DOE”) strategy for tritium production. He later led Fluor Corporation’s government business as Business Group President, Mission Solutions.

Admiral James F. Caldwell retired from the U.S. Navy in 2024 after a distinguished 43-year career. As Director of the Naval Nuclear Propulsion Program from 2015 to 2024, he oversaw the safe, reliable operation of the Navy’s nuclear-powered submarine and aircraft carrier fleet, which under his leadership achieved more than 15 million miles steamed on nuclear power and more than 800 reactor-years of safe operations. He also played a significant role in establishing the framework for Australia’s acquisition of conventionally armed, nuclear-powered submarines under the AUKUS partnership. Earlier, he served as Naval Inspector General and commanded the U.S. Pacific Fleet Submarine Force. He currently serves on the boards of directors of Fluor Corporation and Entergy Corporation.

Admiral William K. Lescher had a distinguished 42-year career with the U.S. Navy, most recently as Vice Chief of Naval Operations, the second-highest-ranking officer in the Navy, from 2020 until his retirement in 2022, and previously as Deputy Chief of Naval Operations for Integration of Capabilities and Resources. He also served as the Joint Staff Deputy Director for Resources and Acquisition and Deputy Assistant Secretary of the Navy for Budget. He currently serves as a Board Director, Executive Advisor and Executive Coach at Boston Consulting Group.

The Honorable Neile Miller is a former Acting Administrator and Principal Deputy Administrator of the NNSA and former Acting Under Secretary of Energy for Nuclear Security under President Barack Obama. She also served as DOE’s Budget Director and was a member of the Credit Review Board and the Risk and Credit Committees of DOE’s Loan Programs Office. Previously, she served two tours at the White House Office of Management and Budget, focusing on nuclear security and nuclear energy programs.

Paul Weedon, Senior Vice President of Exploration, commented, “The recently completed reverse circulation and diamond drilling program adjacent to the Southern Arc and Kassasoko deposits has continued to return very encouraging results beyond the current pit designs. Results such as the 3.9 g/t Au intersection over an estimated true width of 40.8 meters from 228 meters in drill hole DSR1149 highlight the opportunity to further expand the Diamba Sud Mineral Reserve.” Mr. Weedon continued, “At our recently acquired Bambadji properties, exploration drilling has commenced at Kabewest, with six drill rigs operating as part of an $8 million drilling campaign for the remainder of 2026. Kabewest is the largest and most advanced drill-defined target on the property and is located only 2.3 kilometres from the proposed Diamba Sud plant site. Initial drill core samples have highlighted strong similarities to the breccia-hosted mineralization at Diamba Sud, and we look forward to receiving the assay results.”   

Southern Arc Drilling highlights

Since the previous exploration results update in February 2026, a further 196 reverse circulation (“RC”) and diamond drilling (“DD”) holes, totalling 36,592 meters, have been completed at Southern Arc (refer to Figure 1), concluding the program (refer to Fortuna news release dated February 25, 2026, “Fortuna intersects 6.0 g/t gold over 24.1 meters at Southern Arc, Diamba Sud Project, Senegal”). The program successfully identified depth and strike extensions to the northeast and southwest, as well as parallel structures to the southeast, where mineralization remains open. For example, DSR1132 intersected 4.5 g/t gold over an estimated true width of 20.0 meters from 65 meters within a broad zone of mineralization beyond the current pit design (refer to Figure 2). This zone remains open at depth, further demonstrating the open nature of the mineralization. An updated estimate is intended to be prepared for Mineral Resource and Mineral Reserve reporting as at year-end, and further step-out drilling is planned for 2027.

Mineralization at Southern Arc occurs as variable fine stockwork vein arrays and diffuse pyrite-silica flooding, with a strong spatial association to hydrothermal breccias and carbonate units. The system commonly exhibits extensive hematite alteration, consistent with mineralization observed at other Diamba Sud deposits.

Kassasoko Drilling Highlights

A program of 53 RC and DD holes, totalling 8,787 meters, has been completed at Kassasoko since the previous exploration update. This program was designed to test for expansion of the mineralized footprint through step-out drilling and evaluate its link to the nearby Western Splay deposit.  Mineralization remains open at depth and along strike. 

Mineralization at Kassasoko occurs within intercalated hydrothermal breccias, carbonate metasedimentary units, and granitic to dioritic intrusive rocks. It is typically associated with vein arrays preferentially hosted within hydrothermal breccias.

Bambadji, Senegal: Exploration Work Program 

Drilling has commenced on the recently acquired Bambadji project (refer to Figure 3), with five DD rigs and 1 RC rig currently operating as part of an $8 million, 51,000-meter exploration program for the balance of 2026 (refer to Fortuna news release dated August 10, 2026, “Fortuna acquires highly prospective Bambadji Project in Senegal from Barrick and IAMGOLD”). 

Figure 3: Bambadji Gold Project: Location of Exploration Targets

Note: Probable Mineral Reserves of 20.5 million tonnes averaging 1.75 g/t Au, containing 1.15 million ounces of gold have been reported for Diamba Sud (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”).

Following an extensive data review, more than eight drill-ready targets have been identified and prioritized for drilling in 2026. Six drill rigs are currently operating at Kabewest, the most advanced target, located approximately 2.3 kilometers from the proposed Diamba Sud plant site. An initial Inferred Mineral Resource estimate for Kabewest is expected to be included in the Company’s annual Mineral Reserve and Mineral Resource update, planned for publication in the first quarter of 2027. Drilling will progressively advance to additional prospects, including Fatima, Djenebou, Latifa, Kach, Wari, and Kabetea, throughout the remainder of 2026 and into the first half of 2027.

In addition, work is continuing to further refine targets for the 2027 field season across the more than 60-kilometer strike length of the newly acquired permits. Three highly prospective mineralized trends have been identified based on geophysical and geochemical data and supported by field mapping.  Limited historical drilling was generally shallow and widely spaced, with several multi-kilometer gaps along these anomalous gold trends providing compelling targets for Fortuna’s 2026 and 2027 exploration programs.

Geological logging of the initial DD holes at Kabewest has highlighted strong similarities to the nearby Diamba Sud style of mineralization, including extensive hydrothermal brecciation, hematite-silica alteration, and pyrite development (refer to Figure 4), consistent with mineralization previously modelled by Barrick (refer to Figure 5). Assay results are pending.

Integration of the former Barrick technical staff into Fortuna’s Senegal exploration team has been successfully completed, providing valuable continuity, supporting the rapid advancement of field and drilling activities, and enhancing the Company’s understanding of the region’s broader geological architecture.

Refer to Appendix 1 for full details of the drill holes and assay results for this drill program.

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.
