Largo has initiated studies on disseminated copper mineralization based on the results of internal metallurgical test work, which indicate that copper recovery using conventional flotation methods may be possible as a byproduct of its existing operations.
- Largo’s current geological database presents a geological structure favorable to the disseminated mineralization of copper and platinum group metals, associated with vanadium and titanium ore in all deposits of the Maracás Menchen complex.
- Encouraging results in copper recovery occurred as a consequence of metallurgical studies evaluating ways to produce PGMs (platinum, palladium), and gold as byproducts at Largo’s Maracás Menchen mine.
- Preliminary tests indicate a positive response of the copper-rich mineralized material to conventional flotation processes, producing copper concentrates.
- Largo is evaluating using part of its existing ilmenite flotation infrastructure to reduce capital costs and timeline for execution.
- Previous technical reports have not considered the economic impact of potential recovery of copper, PGMs or gold which are now regarded as critical minerals, many of which are trading at near record high prices.
- Largo extended its promissory note with ARG International AG in principal amount of US$6 million until February 2027 under the same terms announced in our August 11, 2025 press release plus an extension fee of 1%.
