NexMetals Mining Announces Updated Selebi Main Resource Estimate

What Happened
NexMetals Mining Corp. (NEXM) filed a Form 8‑K (Item 7.01) on October 1, 2026, furnishing a press release that reports an updated mineral resource estimate for Selebi Main, one of the deposits at its past‑producing Selebi copper‑nickel‑cobalt mine in Botswana. The press release is attached as Exhibit 99.1 and is incorporated by reference. The company stated it has no obligation to update the attached release.

Key Details

• Filing date: October 1, 2026; event: updated mineral resource estimate for the Selebi Main deposit (Selebi mine, Botswana).
• Press release attached as Exhibit 99.1 to the Form 8‑K (information furnished, not filed under Section 18 of the Exchange Act).
• The release uses Canadian NI 43‑101 terms (“mineral resources”, “indicated”, “inferred”); the company notes the SEC’s S‑K 1300 rules differ in some respects.
• Caution: indicated and inferred mineral resources are not the same as mineral reserves; inferred resources have higher uncertainty and generally cannot form the basis for feasibility or economic studies under NI 43‑101 except in limited cases.

Why It Matters
An updated resource estimate is an important technical development that can affect how investors view the potential size and scope of the Selebi Main deposit and NexMetals’ project pipeline. However, the company’s filing emphasizes that these are resource classifications (NI 43‑101) — not proven reserves or economic guarantees — and cautions investors against assuming conversion to higher‑confidence categories or that the resources are economically mineable. This 8‑K furnishes the press release for disclosure purposes only and does not present financial results or a feasibility study.
