8-K: NexMetals Drills High-Grade Copper-Nickel at Selkirk Mine

NexMetals Mining Corp. announced significant assay results from its 2025 metallurgical drill program at the Selkirk Mine, revealing wide, continuous zones of high-grade copper equivalent mineralization.

Summary

• Assay results from the final three holes of the 2025 metallurgical drill program at the past-producing Selkirk Mine in Botswana have been announced.
• Hole SMET-25-009 intercepted 231.00 metres of 1.09% CuEq (0.39% Cu, 0.38% Ni, 0.64 ppm Pd, 0.15 ppm Pt), including 97.00 metres of 1.28% CuEq and 47.90 metres of 1.42% CuEq.
• Mineralization from SMET-25-011 was intercepted below the existing Mineral Resource Estimate (MRE) and conceptual pit, indicating potential for expansion at depth.
• Mineralization intercepted above the MRE and within the current conceptual pit shell demonstrates potential for expansion towards the surface.
• All assay results reported to date from the 2025 program will be incorporated into an updated MRE.
• Drill core from all eleven 2025 holes is now supporting metallurgical testwork at Blue Coast Research in British Columbia to optimize the flowsheet, maximize recoveries, and evaluate concentrate separation.
• The current cut-off of US$25.00 per tonne net smelter return, defined in the 2024 MRE, translates to 0.46% CuEq, with any material above this grade potentially minable.

Sentiment

Score: 8

Explanation: The drill results are very positive, indicating significant scale and grade, with clear expansion potential. Management commentary is highly optimistic, and the ongoing metallurgical work is a logical next step. The risks are standard for exploration and development, but the immediate news is strong.

Positives

• Consistent high-grade mineralization over large intervals, such as 231.00 metres of 1.09% CuEq, indicates a robust deposit.
• The results suggest potential for a low strip ratio, open pit development, which is economically favorable.
• Wide, continuous zones of mineralization are confirmed, suitable for ongoing metallurgical test work.
• Significant expansion potential is demonstrated both at depth (SMET-25-011 below MRE) and towards the surface (above MRE).
• All 2025 assay results will be integrated into an updated MRE, likely leading to an increased resource estimate.
• Metallurgical testwork is underway to optimize processing and maximize recoveries, advancing the project towards development.

Risks

• Capital and operating costs may vary significantly from current estimates.
• Drilling and metallurgical test results are preliminary in nature.
• The ability of exploration results to accurately predict mineralization is uncertain.
• There is a risk regarding the ability to implement drilling, geoscience, and metallurgical work plans effectively.
• Prefeasibility or the ultimate feasibility of mine production is not yet confirmed.
• Delays in obtaining or failures to obtain required governmental, environmental, or other project approvals could occur.
• Uncertainties exist regarding the availability and costs of future financing.
• Changes in equity markets, inflation, and fluctuations in commodity prices could negatively impact the project.
• Delays in the development of projects are possible.
• Other inherent risks associated with the mineral exploration and development industry apply.

Future Outlook

The company plans to incorporate all 2025 assay results into an updated Mineral Resource Estimate. Metallurgical testwork is underway to optimize the flowsheet, maximize recoveries, and advance the evaluation of separating the concentrate, which will inform future development decisions. The company anticipates potential for low strip ratio, open pit development and expansion of the deposit at depth and towards the surface.

Management Comments

• "The takeaway from this metallurgical drilling program is the sizable, mineralized continuity across this deposit."
• "Delivering wide intervals of consistent high-grade mineralization reinforces just how big this system is and gives us the confidence to advance the next stage of our technical work."
• "With all assays from the 2025 metallurgical drill program now reported, our technical team is focused on advancing the metallurgical work currently underway and ongoing assessment of processing options."
• "This next stage will refine the flowsheet, confirm recoveries across the program, and drive the technical work that will inform future development decisions."
• "Selkirk is increasingly demonstrating its potential as a significant additional value driver for NexMetals."

Industry Context

The results for copper, nickel, cobalt, and PGEs are significant given the increasing global demand for these critical metals, particularly in electric vehicles and renewable energy technologies. High-grade, wide intervals, and potential for open-pit development could position Selkirk as a key asset in the competitive base and precious metals mining sector, especially in a mining-friendly jurisdiction like Botswana.

Comparison to Industry Standards

• The consistent grade over large intervals (e.g., 231m of 1.09% CuEq) suggests a robust deposit, potentially comparable to other large-scale base metal projects globally that support open-pit operations.
• The potential for a low strip ratio open pit development is a key economic advantage, often sought after in the industry for cost-effective mining.
• The Selkirk Mine is a "past producing" asset, which often implies existing infrastructure and geological understanding, potentially reducing initial development risks compared to greenfield projects.
• The stated cut-off grade of 0.46% CuEq (US$25.00/tonne NSR) is a standard metric for evaluating economic viability and is competitive for bulk tonnage operations.

Stakeholder Impact

• Shareholders: Positive impact due to strong drill results, indicating potential for increased resource size and value, which could lead to share price appreciation.
• Employees: Continued employment and potential for future growth as the project advances.
• Local Communities (Botswana): Potential for future economic development, job creation, and local benefits if the mine proceeds to development.
• Suppliers/Creditors: Potential for future business opportunities as the project moves towards development and production.

Next Steps

• Incorporate all 2025 assay results into an updated Mineral Resource Estimate (MRE).
• Continue metallurgical testwork at Blue Coast Research to optimize the flowsheet, maximize recoveries, and advance the evaluation of separating the concentrate.
• Technical work will inform future development decisions.

Key Dates

Recommendation

The drill results are exceptionally strong, demonstrating significant scale, high-grade mineralization, and clear expansion potential at the Selkirk Mine. The consistent wide intervals of copper equivalent, including platinum group elements, nickel, and cobalt, are highly attractive for a multi-metal deposit. The confirmation of mineralization below the current MRE and within the conceptual pit suggests substantial upside to the existing resource. With metallurgical work underway to optimize processing, the company is systematically de-risking and advancing a potentially world-class asset. These results significantly enhance the project's economic viability and future development prospects, making it a compelling investment opportunity.
