Buenaventura Announces Voluntary Temporary Ore Treatment Suspension at El Brocal Mine

Press Release by Buenaventura

May 22, 2024

Compañia de Minas Buenaventura S.A.A. (“Buenaventura” or “the Company”) (NYSE: BVN; Lima Stock Exchange: BUE.LM), Peru’s largest publicly-traded precious metals mining company, announces the voluntary temporary suspension of El Brocal’s processing plant facilities. Underground mining works at El Brocal continue uninterrupted per normal, with accumulated mined ore stockpiled for later processing, as has been previously provisioned and authorized, to be processed once concentrator plant operations have resumed.

A small group from the Huaraucaca Community residing adjacent to the El Brocal processing facility entered the property without El Brocal’s authorization. The Company has therefore voluntarily suspended its two El Brocal processing plant operations to ensure the safety of its employees and infrastructure.

Buenaventura maintains a respectful open dialog with all communities surrounding its operations and is therefore confident that discussions with the Huaraucaca community will result in a peaceful and mutually amenable resolution. The Company will continue to maintain a proactively prudent approach at all of its operations, prioritizing the safety of its workers and of its facilities.
