This disclosure represents a material advancement in NexMetals’ resource expansion strategy at the Selebi Mines Project in Botswana. The high-grade intercept of 10.40 metres grading 6.82% CuEq — notably composed of 3.09% Cu and 1.83% Ni — was encountered 320 metres beyond the boundary of the 2024 Mineral Resource Estimate (MRE), directly validating down-plunge continuity of the mineralized system at Selebi Main. Critically, this result is not isolated: it aligns with prior high-grade hits such as SMD-25-205 (11.05 m of 7.31% CuEq) and is part of a systematic 200-metre spaced drilling campaign designed explicitly to convert Inferred Resources into higher-confidence categories. The emergence of a third mineralized horizon in SMD-26-208 — a 7.45-metre interval in the Lower Zone — signals increasing geological understanding and potential for additional resource growth at depth. With 22,061 metres drilled across 8 completed holes, 4 in-progress, and five active rigs, the Company is executing at an accelerated pace toward an updated MRE scheduled for completion in the second half of 2026. Management explicitly states the updated estimate is expected to show 'significantly larger tonnage' than the 2024 MRE, which currently reports 3.0 Mt Indicated at 2.92% CuEq and 24.7 Mt Inferred at 3.40% CuEq. Importantly, all newly reported intervals exceed the 2024 MRE cut-off grade, underscoring consistent grade quality across the expanded footprint. While the filing includes standard NI 43-101 and S-K 1300 cautionary language regarding the uncertainty of Inferred and Indicated Resources — particularly their economic and legal mineability — the scale, grade, and spatial coherence of these results materially de-risk the expansion thesis and strengthen the technical foundation for future feasibility studies.
