Vancouver, British Columbia--(Newsfile Corp. - March 19, 2026) - NexMetals Mining Corp. (TSXV: NEXM) (NASDAQ: NEXM ) (the " Company ") announces assay results from resource gap hole DSLK-25-012 and from the remaining 28 holes of its 34-hole resampling program at the past-producing Copper Nickel Cobalt Platinum Group Elements (" Cu-Ni-Co-PGE ") Selkirk Mine in Botswana.

Assay Highlights:

DSLK-25-012: 101.00 metres of 0.85% CuEq
(0.28% Cu, 0.29% Ni, 0.01% Co, 0.56ppm Pd, 0.12ppm Pt and 0.05ppm Au) DSLK076: 94.20 metres of 0.96% CuEq
(0.34% Cu, 0.30% Ni, 0.02% Co, 0.63ppm Pd, 0.13ppm Pt and 0.06ppm Au) DSLK134: 86.00 metres of 1.06% CuEq
(0.34% Cu, 0.45% Ni, 0.02% Co, 0.55ppm Pd, 0.12ppm Pt and 0.05ppm Au) DSLK211: 180.80 metres of 1.31% CuEq
(0.52% Cu, 0.39% Ni, 0.02% Co, 0.79ppm Pd, 0.17ppm Pt and 0.11ppm Au) DSLK258: 68.00 metres of 0.91% CuEq
(0.28% Cu, 0.32% Ni, 0.02% Co, 0.61ppm Pd, 0.13ppm Pt and 0.05ppm Au)

Footwall Mineralization DSLK077: 6.90 metres of 7.92% CuEq
(5.33% Cu, 1.31% Ni, 0.08% Co, 2.55ppm Pd, 0.56ppm Pt and 0.45ppm Au) DSLK134: 5.90 metres of 2.79% CuEq
(0.63% Cu, 1.76% Ni, 0.07% Co, 0.73ppm Pd, 0.12ppm Pt and 0.04ppm Au)

Why This Matters

Wide intervals of Cu-Ni-Co-PGE mineralization intersected within the conceptual pit shell. High grade footwall mineralization is an exploration target. DSLK-25-012 was drilled to infill a gap in the resource and achieve a minimum drill spacing density of 60m across the deposit. All assay results have been received for the 34-hole resampling program and are ready to be incorporated into an updated Mineral Resource Estimate (" MRE "). Historic drillholes were inconsistently assayed for PGEs, which are expected to contribute approximately one-third of the deposit's net smelter return value. The resampling program captures intervals that were not previously analyzed for PGEs, providing additional data for incorporation into the model. Incorporating PGE values-particularly in mineralization located beyond the current limits of the 2024 Mineral Resource Estimate (the " 2024 MRE ") and within the conceptual pit shell-has the potential to expand the mineral resource and reduce the strip ratio.

Key Takeaway

Wide intervals of Cu-Ni-Co-PGE mineralization exceeding the current resource cut off grade of 0.46% CuEq were mapped outside the 2024 MRE and within the conceptual pit shell. This data will be incorporated into the updated MRE expected in Q2 2026.

Sean Whiteford, CEO of the Company, commented: "The Selkirk drilling and resampling program continues to deliver wide intervals of Cu, Ni and PGE mineralization. We will be incorporating these assay results, combined with new metallurgical results, into an updated MRE anticipated in Q2 2026. Additionally, the exceptional results from DSLK077 (6.90m at 7.92% CuEq) indicate a potential new footwall zone for further follow up."

¹Length refers to drillhole length and not true width.
²True thickness is estimated using the MRE wireframe where available. Note that all holes did not cross the entire deposit.
³CuEq% calculated using the formula Cu% + Ni%*(55.605/53.913) + Pd g/t*(22.948/53.913) + Pt g/t*(14.891/53.913) using metal prices and recoveries listed in the 2025 Technical Report (as defined below).
