NexMetals extends thick massive sulphides to 1.45 km at Selebi Main

Vancouver, British Columbia--(Newsfile Corp. - August 17, 2026) - NexMetals Mining Corp. (TSXV: NEXM) (Nasdaq: NEXM) (" NEXM " or the " Company ") is pleased to report visual results from drill hole SMD-26-219, part of its ongoing surface drilling program targeting the Flexure Zone (" Flexure Zone ") at the Selebi Main deposit in Botswana (see Figure 1). The hole intersected multiple thick intervals of semi-massive and massive sulphide mineralization, extending the emerging high-grade mineralized trend by approximately 450 metres beyond previously reported drilling. The trend, located within the Flexure Zone and outside the 2024 Mineral Resource Estimate (" 2024 MRE "), continues to demonstrate significant expansion potential. Drill core photos from SMD-26-219 are shown in Figure 2.

What You Need to Know: Emerging Thick, High-Grade Trend Extended by a Further 450 metres to 1.45 kilometres

Emerging High-Grade Trend Extended: Drill hole SMD-26-219 is located approximately 450 metres down-plunge of SMD-25-205 (11.05 metres of 7.31% CuEq, see news release dated February 26, 2026) and 175 metres along strike of SMD-26-213 (22.90 metres of 3.02% CuEq). The new visual intercept provides further evidence that the emerging thick, high-grade mineralized trend continues at depth and extends well beyond the 2024 MRE.

Strong Visual Sulphide Mineralization in Two Zones: Hole SMD-26-219 intersected multiple intervals of sulphide mineralization, including a 20.0 metre mineralized zone that includes 1.6 meters of massive sulphides in the Main Zone and a 7.55 metre interval that includes 6.60 metres of massive sulphides in the Lower Zone.

Unlocking Footwall Potential: The 6.60 metre interval of massive sulphides, from 1,910.15 to 1,916.75 metres in the lower zone correlates with the lower zone interval in SMD-26-213 (7.45 m of 2.52% Cu and 1.54 % Ni) l
