NexMetals upgrades Selkirk copper resource to 1.1B lb.
NexMetals Mining said its Selkirk copper-nickel-PGE project in Botswana now has about 1.1 billion lb. copper equivalent (CuEq) in indicated resources after converting nearly 70% from inferred, driven by re-assaying and twin drilling. NexMetals reported 78.2 million tonnes at 0.66% CuEq, plus 15.1 million inferred tonnes at 0.60% CuEq. The upgrade raises contained CuEq inventory 63% vs. 2024, mainly from improved recoveries and adding payable cobalt, silver and gold.
How this was made

The 30-second read
Why it matters
The Selkirk resource update converts inferred to indicated via re-assaying and twin drilling, raising contained CuEq inventory by 63% and adding payable cobalt, silver, and gold to the inventory mix.
Market read
A concrete resource conversion and inventory increase can re-rate a microcap’s risk profile, but the stock’s partial giveback suggests broader metals tape still constrains follow-through.
What to watch
The article notes metal price changes had minimal net impact versus 2024, implying the key driver is conversion/recoveries—traders may still discount near-term value until capex/grade-to-recovery and payable metal assumptions are validated.
Background
NexMetals is redeveloping the Selebi and Selkirk past-producing copper-cobalt-nickel mines in Botswana after acquiring them out of liquidation in 2022.
Ticker impact
NexMetals upgraded its Selkirk copper-nickel-PGE resource to ~1.1B lb CuEq, converting inferred to indicated and boosting inventory 63%.
Likely near-term positive bias, though follow-through depends on continued metal price weakness and subsequent drilling/feasibility milestones.
The article provides concrete resource tonnage/grade, category conversion, and a stated 63% inventory increase, plus notes the stock initially jumped ~10% then faded.
Market effects
Supports sentiment for polymetallic copper/cobalt/nickel development stories where resource confidence and recoveries improve financing optionality.
Botswana-focused critical metals narrative may attract incremental attention to local project pipelines.
Adds incremental supply-side optionality to copper-equivalent inventories, but scale is small versus global markets.
Counterpoint
A resource upgrade can be largely technical; without updated economics (PFS/FS) and permitting timelines, the market may fade the initial enthusiasm.
