Metalero Mining Corp. is a Canadian junior mineral exploration company engaged in the exploration and development of silver, gold and copper projects in the Americas, with a focus on district-scale land positions in Bolivia and British Columbia; the company also retains Nevada mineral properties available for sale or option as part of a restructuring and portfolio realignment. Founded in 2018 and headquartered in Edmonton, Alberta, Metalero operates through the Metals Group of companies and is listed on the TSX Venture Exchange under the symbol MLO. Its core assets include approximately 230 square kilometres adjacent to Bolivia’s San Cristobal silver mine in the Uyuni belt, including the San Cristobal East and San Cristobal South projects, as well as a 173 square kilometre copper-gold land package along the Mount Polley trend in British Columbia, where it is advancing the Benson Project and targets such as Sundberg and Cantin. The company’s recent developments include a strategic expansion into Bolivia through the acquisition of additional concessions next to a major silver producer, a $3.0 million private placement announced in May 2026 following an oversubscribed financing in March 2026, and a shift to semi-annual reporting; it also reported ongoing exploration results and positioned its first drill campaign in Bolivia for 2027. The company was formerly known as Cortus Metals Inc. and changed its name to Metalero Mining Corp. in February 2024.
