Largo shares surge 15% as it adds copper, PGMs to Brazil mine

AI desk brief

Largo shares jumped nearly 15% after Brazil’s National Mining Agency approved the company to produce and sell copper, platinum group metals (PGMs), nickel and cobalt as by-products from its Maracás Menchen vanadium mine. The stock was trading at $0.80 in New York, implying a market cap of about $108 million. The development lets Largo move from industrial-scale testing toward commercializing a copper-PGM concentrate using existing processing infrastructure.

The company says it will use its current vanadium plant and ilmenite flotation setup rather than build a separate operation, which should keep capex low if ramp-up succeeds. Largo argued the copper-PGM stream could carry higher margins than ilmenite concentrate, but it did not provide production targets, sales volumes or revenue guidance. The approval also extends to nickel and cobalt recovery, broadening the mine’s by-product profile.

For precious metals traders, the direct market implication is limited: this is a company-specific supply development, not a broad PGM demand or price signal. Still, it marginally points to incremental future PGM supply from an existing operation if commercialization works, while the key near-term catalyst is whether Largo can convert test work into sustained output and signed commercial sales.
