8-K: NexMetals Selkirk Drills High-Grade CuEq Near Surface

NexMetals Mining Corp. announced strong metallurgical drilling results from its Selkirk Mine in Botswana, revealing significant near-surface copper equivalent mineralization and expansion potential.

Summary

• Assay results from 2 of 12 metallurgical drill holes at the Selkirk Mine in Botswana were released.
• Drill core from eleven holes will be used for ongoing metallurgical testwork and flowsheet optimization.
• Hole SMET-25-003 intersected 201.30 metres grading 0.91% CuEq, including 158.75 metres at 1.00% CuEq.
• Hole SMET-25-002 intersected 85.00 metres grading 0.98% CuEq.
• Mineralization was identified outside the current Mineral Resource Estimate (MRE) but within the conceptual pit shell, indicating expansion potential towards the surface.
• Near-surface mineralization, such as 19.90 metres of 0.58% CuEq starting at 26.10 metres from surface in SMET-25-002, supports open-pit development with a low strip ratio.
• The current cut-off grade for potential mining is 0.46% CuEq, based on a US$25.00 per tonne net smelter return.

Sentiment

Score: 8

Explanation: The drilling results are very positive, showing high-grade, wide intercepts near surface and significant expansion potential. Management's comments are highly optimistic, indicating results exceeded expectations. This is a strong exploration update for a mining company.

Positives

• Significant wide intervals of continuous high-grade copper equivalent (CuEq) mineralization were intersected, including 201.30 metres of 0.91% CuEq and 158.75 metres of 1.00% CuEq.
• Mineralization extends beyond the current Mineral Resource Estimate (MRE) but remains within the conceptual pit shell, indicating strong potential for deposit expansion towards the surface.
• The presence of large widths of near-surface mineralization supports the viability of open-pit development with a potentially low strip ratio.
• The results provide essential material for ongoing metallurgical testwork, which aims for variability testing and flowsheet optimization.
• The CEO expressed that results "delivered above and beyond what we have anticipated," confirming the scale and potential upside of the Selkirk deposit.

Risks

• Capital and operating costs may vary significantly from estimates.
• Drilling and metallurgical test results are preliminary in nature.
• Exploration results may not accurately predict mineralization.
• The Company's ability to implement its drilling, geoscience, and metallurgical work plans is subject to uncertainties.
• Prefeasibility or feasibility of mine production is not guaranteed.
• Delays in obtaining or failures to obtain required governmental, environmental, or other project approvals.
• Uncertainties regarding the availability and costs of future financing.
• Changes in equity markets, inflation, and fluctuations in commodity prices.
• Potential delays in the development of projects.
• General risks inherent in the mineral exploration and development industry.

Future Outlook

The Company plans to continue releasing assay results from the 2025 metallurgical drilling program on an ongoing basis. It anticipates that ongoing metallurgical testwork will support flowsheet optimization and that the identified mineralization outside the current MRE indicates significant potential for resource expansion and open-pit development with a low strip ratio. The Company is focused on metallurgical optimization and resource growth to define the full scale and potential of the Selkirk deposit.

Management Comments

• "These new drill results have delivered above and beyond what we have anticipated including large, continuous zones of mineralization that confirm the scale of just how big the Selkirk deposit could be."
• "By collecting both base metal and PGE assays throughout the entirety of each hole, we have identified wide intervals of mineralization both above the current MRE, yet still within the conceptual pit shell and also immediately below the conceptual pit."
• "Combined with the ongoing resampling and metallurgical programs, these results not only provide essential material for processing studies but also indicate meaningful opportunities to improve the strip ratio."
• "Selkirk continues to demonstrate substantial upside, and with our dual focus on metallurgical optimization and resource growth, we are increasingly defining the full scale and potential of this deposit."

Industry Context

The results from NexMetals' Selkirk Mine are significant in the context of increasing global demand for base metals (copper, nickel, cobalt) and Platinum Group Elements (PGEs), driven by electrification, renewable energy, and automotive industries. Discoveries of wide, near-surface, high-grade mineralization, especially in a past-producing mine, are highly valued as they can lead to lower-cost open-pit operations, which is a key competitive advantage in the mining sector. Botswana is also a favorable mining jurisdiction, adding to the project's attractiveness.

Stakeholder Impact

• Shareholders: Positive impact due to strong drill results, indicating potential for resource expansion, improved project economics (low strip ratio, open-pit potential), and future value creation.
• Employees: Potential for increased employment opportunities as the project advances towards development and production.
• Local Communities (Botswana): Potential for economic benefits through job creation, local procurement, and infrastructure development if the mine progresses.
• Creditors/Lenders: Improved confidence in the project's viability and future cash flow potential, potentially easing future financing efforts.

Next Steps

• Release of assay results from the remaining 10 metallurgical drill holes on an ongoing basis.
• Ongoing metallurgical testwork at Blue Coast Research labs for variability testing and flowsheet optimization.
• Continued focus on metallurgical optimization and resource growth to define the full scale and potential of the Selkirk deposit.

Key Dates

Recommendation

The drilling results are exceptionally strong, demonstrating wide, high-grade copper equivalent mineralization near the surface, which significantly enhances the Selkirk project's economic viability and expansion potential. The discovery of mineralization outside the current MRE but within the conceptual pit shell suggests substantial upside for resource growth and a favorable open-pit mining scenario with a low strip ratio. Management's enthusiastic comments reinforce the positive outlook, indicating that these results exceeded expectations. This update de-risks the project further and points to a significant increase in the asset's intrinsic value, making it a compelling investment opportunity.
