8-K: NexMetals Drills High-Grade Copper-Nickel at Selebi North

NexMetals Mining Corp. reports impressive assay results from three drill holes at its Selebi North Underground deposit, confirming high-grade copper and nickel mineralization.

Summary

• Assay results from three additional drill holes (SNUG-25-191, 192, 194) at the Selebi North Underground (SNUG) deposit successfully intersected high-grade mineralization.
• Drill hole SNUG-25-194 intersected 32.45 metres of 4.61% CuEq (1.61% Cu, 1.46% Ni) in the South Limb.
• This intersection included higher-grade sections: 7.90 metres of 5.85% CuEq (1.11% Cu, 2.30% Ni) and 9.65 metres of 5.88% CuEq (2.35% Cu, 1.72% Ni).
• Results continue to strengthen confidence in the size and continuity of the deposit.
• Since the initial 2024 Mineral Resource Estimate (MRE), an additional 42,000 metres of drilling has been completed, extending mineralization over 315 metres beyond the lower extent of the resource.
• The 2025 Selebi North Underground resource expansion program involved 9,617 metres of drilling across 10 completed holes, 6 abandoned holes, and 1 in-progress hole.

Sentiment

Score: 8

Explanation: The assay results are very positive, demonstrating high-grade copper-nickel mineralization over significant widths and extending the known deposit. This significantly de-risks the project and enhances its growth potential.

Positives

• Successfully intersected high-grade mineralization in additional drill holes at the Selebi North Underground deposit.
• Drill hole SNUG-25-194 returned a significant intersection of 32.45 metres of 4.61% CuEq (1.61% Cu, 1.46% Ni).
• High-grade sections within SNUG-25-194 include 9.65 metres of 5.88% CuEq (2.35% Cu, 1.72% Ni).
• Results confirm high-grade continuity along the down plunge extension of the South Limb.
• Confidence in the growth potential and size of the deposit is reinforced.
• Mineralization has been extended over 315 metres beyond the lower extent of the 2024 MRE.

Risks

• Capital and operating costs may vary significantly from estimates.
• Metallurgical test results are preliminary and may not be indicative of final outcomes.
• Exploration results may not accurately predict mineralization, prefeasibility, or the feasibility of mine production.
• The mineralized corridor may not continue at depth as expected.
• Assay results may not be as anticipated or received when expected.
• The continuity and scale of the South Limb, N2, and N3 mineralized systems may not be as expected.
• Additional drilling is needed to properly determine the true width of mineralization on each limb and define the folded mineralization.
• Delays in obtaining or failures to obtain required governmental, environmental, or other project approvals.
• Uncertainties exist regarding the availability and costs of future financing.
• Changes in equity markets, inflation, and fluctuations in commodity prices could negatively impact operations.
• Delays in the development of projects are possible.
• Other risks inherent in the mineral exploration and development industry.

Future Outlook

The company plans to update its Mineral Resource Estimate (MRE) in 2026, incorporating the 2025 resource expansion drillholes and updated metallurgical test results. Drilling is ongoing, with drill hole SNUG-25-200 currently testing the down plunge extension of N3. Upon completion, the SNUG drill will transition to surface drilling for the 2026 Selebi Main resource expansion program. Assay results for SNUG-25-197 and SNUG-25-199 are currently pending.

Management Comments

• "These impressive assay results from SNUG-25-194 continue to confirm high grade continuity along the down plunge extension of the South Limb and reinforce our confidence in the growth potential of the deposit." Sean Whiteford, CEO.

Industry Context

These results indicate successful exploration and potential resource expansion for copper and nickel, which are critical metals for the global energy transition, including electric vehicles and renewable energy infrastructure. High-grade intersections in established deposits like Selebi North are significant in an industry facing increasing demand and potential supply constraints for these metals. NexMetals' focus on redeveloping past-producing mines aligns with a broader industry trend of optimizing existing assets and exploring brownfield sites to meet future demand.

Comparison to Industry Standards

• The reported CuEq grades, such as 4.61% over 32.45 metres and sections up to 6.09% CuEq, are considered high-grade for bulk tonnage copper-nickel deposits globally, often exceeding average grades of many operating mines.
• For context, many large-scale copper mines typically operate at average grades below 1% Cu, and high-grade nickel deposits often range from 1-3% Ni, making NexMetals' reported combined CuEq values very strong.
• While no specific comparable companies or projects are mentioned in the filing, these grades would be competitive with or exceed those of many major operating copper-nickel mines or advanced-stage projects, such as those operated by Norilsk Nickel or Vale in their high-grade zones.
• The extension of mineralization over 315 metres beyond the existing resource boundary is a significant positive indicator for potential resource growth, which is a key metric for exploration success and compares favorably to typical brownfield exploration successes.

Stakeholder Impact

• Shareholders: Positive impact due to confirmed high-grade mineralization and extended resource potential, which could lead to increased valuation.
• Employees: Continued employment and potential for growth as the project advances.
• Local Communities: Potential for future economic benefits if the project moves towards development.

Next Steps

• Update the Mineral Resource Estimate (MRE) with the 2025 resource expansion drillholes and updated metallurgical test results in 2026.
• Continue drilling with drill hole SNUG-25-200 to test the down plunge extension of N3.
• Transition the SNUG drill to surface drilling for the 2026 Selebi Main resource expansion program.
• Deliver assay results for SNUG-25-197 and SNUG-25-199, which are currently pending.

Key Dates

Recommendation

The drill results are exceptionally strong, confirming high-grade copper-nickel mineralization over significant widths and extending the known deposit substantially. This de-risks the project, significantly enhances its resource growth potential, and provides a strong foundation for an updated Mineral Resource Estimate. Given the strategic importance of copper and nickel, these results are highly positive for the company's long-term value proposition.
