(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - August 20, 2025) - NexMetals Mining Corp. (TSXV: NEXM) (NASDAQ: NEXM) (the " Company " or " NEXM ") reports the successful completion of its accelerated drill program, previously announced on June 24, 2025, at the past-producing copper-nickel-cobalt-platinum group elements (" Cu-Ni-Co-PGE ") Selkirk Mine in Botswana. Drilling totalled 3,903 metres and was completed in 12 holes. A further 522 metres were completed in three holes testing Versatile Time-Domain Electromagnetic (" VTEM" ) targets (see news release dated July 9, 2025). Fourteen holes were surveyed with borehole electromagnetics (" BHEM ").

Highlights: Why This Matters

• BHEM Results - 14 of the 15 2025 holes were surveyed and returned BHEM anomalies that are known to correlate directly with massive or semi-massive sulphide mineralization (the host for the Cu-Ni-Co-PGE) (see Figure 1) . Surveys from the deepest holes identified modeled plates located below the Mineral Resource Estimate (" MRE "). Drill hole DSLK-25-015 will be surveyed with BHEM in the coming days.
• Deposit Type - Selkirk mineralization is primarily disseminated sulphides with average thickness greater than 100 metres containing narrow intervals of massive sulphides.
• Proven Targeting Method - The strong and consistent correlation with massive sulphides has confirmed that BHEM is a proven exploration tool for identifying additional mineralization at Selkirk.
• New Discovery Opportunities from VTEM - Two of the three VTEM drill holes are located along the same geological horizon of the Selkirk deposit and intersected intervals of massive and disseminated sulphides (Figure 2). Assays are pending.

Funded Next Catalysts

• Re-open deep historical holes outside the MRE and survey with BHEM starting with historical hole DSLK007. This hole was drilled in 2003 and intersected disseminated sulphides over 142 metres with sporadic narrow massive sulphide intervals grading up to 2.99% Ni. This intersection is located 480 metres down plunge of the mineralized envelope.
• Integrate BHEM results with geological and assay data to refine 3D models of mineralized zones.
• Pending assay results, follow-up drilling of mineralized zones associated with the VTEM targets.
• Complete additional surface geophysical surveys over prospective geology in the Selkirk Mining Licence and the Selkirk Prospecting Licenses.

Morgan Lekstrom, CEO of the Company, commented : "Our accelerated drill program is delivering results on multiple fronts. The consistent BHEM responses tied directly to sulphide mineralization confirm we have a high confidence targeting technology that has already been successfully demonstrated at Selebi. Additionally, the early success of drilling VTEM anomalies opens new discovery opportunities. This is exactly the kind of momentum we want to see as we work to unlock the full potential of Selkirk."

BHEM Surveys

The BHEM surveys at Selkirk utilized the Crone PEM system operated by local Batswana staff. Survey data is collected using a 3-component fluxgate probe collecting full waveform data. Surveys have been collected using a timebase of 500ms (0.5 Hz). The data has been processed to a calculated residual step response to better quantify the conductive sources.
