NexMetals intercepts 7.55 m of 6.48% CuEq at SMD-26-219

Vancouver, British Columbia--(Newsfile Corp. - September 23, 2026) - NexMetals Mining Corp. (TSXV: NEXM) (NASDAQ: NEXM) (" NEXM " or the " Company ") is pleased to report assay results from drill hole SMD-26-219 and a new visual intercept from drill hole SMD-26-217, part of its ongoing surface drilling program at the Selebi Main deposit in Botswana (see Figure 1). The results continue to support the Company's data-driven exploration model and highlights the potential for continued growth of the Selebi Main mineralized system.

SMD-26-219 returned 7.55 metres grading 6.48% CuEq (2.70% Cu and 1.83% Ni), confirming another thick, high-grade massive sulphide intersection along an emerging high-grade trend that has now been defined over approximately 1.5 kilometres (the " High-Grade Trend ").

SMD-26-217 extended the High-Grade Trend by a further 100 metres toward Selebi North and intersected a combined total of 38.65 metres of disseminated to massive sulphide mineralization across three zones. The hole represents the deepest significant intercept of mineralization along the trend and confirmed the Main and Lower Zones, while also, for the first time, intersecting a Third Zone of massive sulphide mineralization approximately 9 metres below the Lower Zone. Together, the three zones represent one of the thickest mineralized intervals encountered during the program to date and provide further evidence that the High-Grade Trend continues laterally through the Flexure Zone toward Selebi North. Assays are pending.

Why This Matters

Exceptional grades continue to define the High-Grade Trend. SMD-26-219 returned 7.55 metres grading 6.48% CuEq, building on a series of thick, high-grade intersections and reinforcing the strength and consistency of mineralization across the grow
