8-K: NexMetals Drills High-Grade Sulphides, Expands Botswana Resource

NexMetals Mining Corp. reports strong initial drilling results from its Selebi Main and Selebi North deposits in Botswana, indicating significant resource expansion potential.

Summary

• Strong initial results from the ongoing surface drilling program targeting the gap between the Selebi Main and Selebi North deposits in Botswana.
• Drilling has intersected new mineralization outside the current Mineral Resource Estimate (MRE) and demonstrates potential for additional mineralized horizons at depth.
• Initial hinge drill hole SMD-25-201 intersected three zones of massive and semi-massive sulphide mineralization, including 3 metres of massive sulphides, representing the thickest Lower Zone intersection drilled to date.
• Drill hole SMD-25-205, a data-driven follow-up hole, intercepted 11.05 metres of mineralization, including two massive sulphide intervals of 3.50 metres and 5.80 metres.
• Borehole electromagnetic (BHEM) results identified a high-priority anomaly, the 'Super Conductor,' establishing the next immediate drill target, which reflects the highest-amplitude BHEM response recorded at Selebi Main in the Company's history.
• Multiple drill holes have identified indications of a potential third mineralized horizon at Selebi Main.
• All planned hinge holes completed to date intersected mineralization that correlates with modeled BHEM plates, reinforcing the belief that mineralization is continuous between Selebi Main and Selebi North.
• New Selebi Main massive sulphide intercepts suggest an increase in thickness at depth, potentially enhancing project economics.
• A total of 11,928 metres in 5 completed holes, 1 hole extension, 1 abandoned hole, and 2 in-progress holes have been completed as part of the surface drilling program.
• Assay results for SMD-25-201 include 2.70m at 0.87% Cu, 1.63% Ni, 0.07% Co (4.24% CuEq) and 3.80m at 1.47% Cu, 1.90% Ni, 0.08% Co (5.38% CuEq), including 3.00m at 1.72% Cu, 2.35% Ni, 0.10% Co (6.56% CuEq).

Sentiment

Score: 8

Explanation: The filing reports strong initial drilling results, significant new mineralization, and the discovery of a high-priority 'Super Conductor' anomaly, all pointing to substantial resource expansion potential and positive project economics. The management commentary is highly optimistic, reinforcing the belief in a much larger mineralized system.

Positives

• Strong initial drilling results expanding mineralization beyond current MRE boundaries.
• Discovery of the 'Super Conductor,' the highest-amplitude BHEM response ever recorded at Selebi Main, indicating significant untapped potential.
• Thickest Lower Zone intersection to date (3 metres of massive sulphides in SMD-25-201).
• Significant intercept of 11.05 metres of mineralization, including 3.50m and 5.80m massive sulphide intervals in SMD-25-205.
• Confirmation of continuous mineralization between Selebi Main and Selebi North.
• New massive sulphide intercepts suggest an increase in thickness at depth, potentially improving project economics.
• High-grade assay results from SMD-25-201, including 3.00m at 1.72% Cu, 2.35% Ni, 0.10% Co (6.56% CuEq).

Negatives

• Assays are pending for several significant intercepts (SMD-25-204, SMD-25-205, SMD-25-207), introducing a delay in full data assessment.
• One drill hole (SMD-25-206) was abandoned due to casing deflection.
• Drill hole SMD-25-207 did not intersect the strongest part of the 'Super Conductor' target, requiring further drilling to fully define the anomaly.

Risks

• Capital and operating costs may vary significantly from estimates.
• Drilling and metallurgical test results are preliminary in nature.
• The ability of exploration results to accurately predict mineralization is uncertain.
• The Company's ability to implement its drilling, geoscience, and metallurgical work plans on its properties may be impacted by various factors.
• Uncertainties exist regarding the prefeasibility or feasibility of mine production.
• Delays in obtaining or failures to obtain required governmental, environmental, or other project approvals could occur.
• The availability and costs of future financing are uncertain.
• Changes in equity markets, inflation, and fluctuations in commodity prices could adversely affect the project.
• Delays in the development of projects are possible.
• Other inherent risks are involved in the mineral exploration and development industry.
• Additional risks are detailed in the Company's filings with the U.S. Securities and Exchange Commission on EDGAR and public disclosure record on SEDAR+.

Future Outlook

The Company believes that work completed in 2026 will significantly advance the projects and fully establish the scale and opportunity of the Selebi deposits. They anticipate additional mineralized horizons at depth and that mineralization extends well beyond current resource boundaries, with continuity between Selebi Main and Selebi North. The current priority is targeting the 'Super Conductor' to define thicker mineralization, which is expected to meaningfully expand the Inferred resource base.

Management Comments

• Sean Whiteford, CEO: "What we are seeing at Selebi Main clearly demonstrates that high-grade mineralization continues well beyond the extents of the current MRE. These new, widely spaced, intercepts of mineralization are the result of fundamental, data-driven brownfields exploration. Additionally, every hole drilled in the initial hinge drilling program has intersected mineralization indicating the full-scale potential of the Selebi complex. The focus for 2026 will be resource expansion at Selebi Main targeting additional mineralization that will be incorporated into an updated MRE. The current priority is targeting the Super Conductor with the goal of further defining areas of thick mineralization. We believe the results of the drilling to date continue to validate our view that Selebi Main and Selebi North form a much larger mineralized system than previously recognized."
• Sharon Taylor, V.P. Exploration & Chief Geophysicist: "The Super Conductor off-hole anomaly in sd144x is the highest amplitude calculated residual step response anomaly seen anywhere on the property. It is especially significant given the 1000 milliseconds time base (0.25 Hz) of the survey which means the conductor continued responding long after transmitter shut off. Given the only known conductors in the immediate vicinity of the Selebi Mines are copper-nickel sulphides, the importance of this anomaly for targeting additional resource expansion cannot be over-stated."

Industry Context

The discovery of significant copper-nickel-cobalt mineralization aligns with the increasing global demand for battery metals and critical minerals, driven by the electric vehicle and renewable energy sectors. Botswana is a known mining jurisdiction, and successful exploration here could position NexMetals to capitalize on these long-term commodity trends. The focus on resource expansion in a brownfield site is a common strategy in the mining industry to leverage existing infrastructure and geological understanding.

Stakeholder Impact

• Shareholders: Potential for increased share value due to resource expansion and improved project economics. Increased confidence in the company's exploration strategy.
• Employees: Continued employment and potential for growth in exploration and development activities in Botswana.
• Local Communities in Botswana: Potential for economic benefits through ongoing exploration and future mine development, including job creation and local procurement.
• Creditors/Lenders: Improved collateral and reduced risk profile if resource expansion leads to a more robust project.

Next Steps

• Conduct a BHEM survey on SMD-25-203 upon completion of drilling.
• Further define areas of thick mineralization by targeting the 'Super Conductor.'
• Incorporate additional mineralization into an updated Mineral Resource Estimate (MRE) in 2026.
• Continue the planned 2026 drill program, with sequencing decisions informed by initial results.
• Ongoing down-hole geophysics, drilling, and metallurgical programs aimed at expanding resources and supporting future economic studies.

Key Dates

Recommendation

The drilling results are exceptionally strong, indicating significant expansion of known high-grade mineralization and the discovery of a major new target ('Super Conductor'). The intercepts are thick and show high copper and nickel equivalent grades. This materially enhances the project's economics and resource potential, suggesting a substantial increase in the company's intrinsic value. The confirmation of a larger, continuous mineralized system between Selebi Main and Selebi North de-risks future exploration and development. This news is highly positive and likely to drive significant upward re-rating of the stock.
