NexMetals Mining Corp has delivered a material scale increase at its Botswana copper-nickel project: the inferred mineral resource at Selebi Main rose 72% to 32.47 million tonnes. The updated resource grades 1.53% copper and 0.98% nickel, giving traders and investors a concrete measure of how exploration is expanding the redevelopment opportunity.

The most important detail behind the headline number is the source of the growth. New drilling accounted for 91% of the added mineral tonnage, suggesting the increase was driven primarily by additional geological information rather than a simple revision to an existing estimate. The next data point remains outstanding: NexMetals has not yet released the Selebi North mineral resource estimate.

According to the company’s resource update, Selebi Main now stands at 32.47 million tonnes on an inferred basis. That classification matters. An inferred mineral resource reflects geological evidence and sampling that are not yet sufficient to establish the same level of confidence as more advanced resource categories. The figure is therefore a significant exploration milestone, but it remains part of an ongoing technical and redevelopment process.

Why the 72% increase matters

For market participants, the numbers create three clear points of focus:

• Scale: The inferred resource increased 72% to 32.47 million tonnes.
• Grade: The estimate carries grades of 1.53% copper and 0.98% nickel.
• Drilling contribution: New drilling represented 91% of the added mineral tonnage.

That combination may strengthen the project’s underlying resource narrative. It also gives investors a more measurable way to assess exploration progress: not merely the number of drill holes, but the amount of additional tonnage incorporated into the estimate.

Selebi’s critical-minerals angle

Selebi is a copper-and-nickel deposit in Botswana, and those commodities place the project within the critical-minerals conversation. Copper is a key industrial metal, while nickel is associated with battery materials and other industrial applications. For critical-minerals investors, a project containing both metals may offer broader commodity exposure than a single-metal development, although the resource update alone does not establish future production, economics, or timing.

NexMetals is focused on redeveloping a past-producing mine, making the Selebi story a redevelopment case rather than a purely greenfield exploration concept. The company is dual-listed on the TSX Venture Exchange and Nasdaq. No share-price move is specified in the resource announcement, so the 72% resource increase—not an assumed market reaction—is the relevant measurable development here.

The pending Selebi North estimate

The unresolved variable is Selebi North. Its mineral resource estimate remains pending, leaving investors with an incomplete picture of the broader Selebi project. A future update could add further definition to the redevelopment opportunity, but its size, grade, and timing are not provided in the current announcement.

For now, the investment case has a clear data point and a clear watch item: Selebi Main’s inferred resource has expanded to 32.47 million tonnes, with drilling responsible for 91% of the added tonnage, while Selebi North remains unreported.
