Buenaventura Announces Strike at Uchucchacua Mine

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, today announced that the local community surrounding the Company’s Uchucchacua mine initiated a strike at midnight on September 13, 2021. Mine operations have therefore since been suspended as access has been blocked. However, essential work associated with mine maintenance and functionality, including water drainage, water treatment and tailings dams inspection, continue without interruption.

The strike results from the community’s claim that Buenaventura has violated agreements signed in 2012 and 2018. However, Buenaventura has complied with all related commitments and obligations. This has also been communicated to the community as the Company has made itself available twice a month for meetings with community representatives. Meetings are also scheduled in special circumstances, which unfortunately was not possible in the current situation despite Buenaventura’s frequent attempts.

Buenaventura has proposed a meeting with community representatives to support a productive dialog and resulting solution in order to end the strike. Should a solution not be reached in the subsequent days, the Company expects a negative effect on third quarter results. However, should this be necessary, Buenaventura will revise its current mine plan accordingly to mitigate adverse impacts on its operations and recover any related shortfall over the balance of the year as well as any potential residual effects on 2022 results.

It’s important to note that Buenaventura has implemented several social projects benefitting local communities in those areas surrounding its mines as a key component of the Company’s longstanding dedication and commitment to Environmental and Social Responsibility.

Buenaventura will continue to provide relevant updates.
