[{"type":"text","content":" Vancouver, British Columbia--(Newsfile Corp. - May 7, 2026) - NexMetals Mining Corp. (TSXV: NEXM) (NASDAQ: NEXM) (\"NEXM\" or the \"Company\") is pleased to report assay results from its surface drilling program at the Selebi Mines Project in Botswana, targeting the gap between the Selebi Main and North deposits and advancing resource expansion. The Selebi Mines Project comprises two deposits, Selebi Main and Selebi North, which host a combined Mineral Resource of 3.0 Mt at 2.92% CuEq (0.90% Cu and 0.98% Ni) Indicated and 24.7 Mt at 3.40% CuEq (1.50% Cu and 0.92% Ni) Inferred. Drilling has intersected mineralization 320 metres beyond the 2024 Mineral Resource Estimate (\"2024 MRE\"), confirming strong down-plunge continuity and highlighting the potential for additional mineralized horizons at depth at Selebi Main. What You Need to Know: Mineralization Expanded at Selebi Main SMD-26-209 intersected 10.40 Metres of 6.82% CuEq (3.09% Cu, 1.83% Ni), located 320 metres down-dip of the 2024 MRE. Results are consistent with SMD-25-205 (11.05 metres of 7.31% CuEq, see news release dated February 26, 2026), located 350 metres to the northeast, demonstrating expansion potential within the Flexure Zone, extending down-dip and down-plunge from Selebi Main. SMD-25-201 and SMD-25-203 tested the southern portion of the 2km gap between the Selebi Main and Selebi North deposits: SMD-25-201 intersected multiple intervals of massive sulphide mineralization (see news release dated January 20, 2026). SMD-25-203 intersected 16.10 metres of sulphide mineralization, located 385 metres down-plunge of SMD-25-201 and 620 metres beyond the 2024 MRE (see Table 1). Based on drilling results and borehole electromagnetic (\"BHEM\") data, follow-up drilling is now focused on a 200-metre spacing, with the goal of incorporating these new results into an updated MRE expected to be completed in the second half of 2026. SMD-26-208 intersected three mineralized horizons, including a lower zone with a thickness of 7.45 metres (see Table 1). Four holes are currently in progress at Selebi Main, with a fifth, Company-owned, drill rig recently added to accelerate the program. What Does This Mean Confirmation that the Selebi Main mineralization extends well beyond 2024 MRE boundaries. A third zone is emerging beneath the two known zones. The updated MRE is expected to hav...
