Buenaventura Announces Acquisition of 51% of Chucapaca Project

Compañía de Minas Buenaventura S.A.A. (“Buenaventura”) (NYSE:BVN; Lima Stock Exchange:BUE.LM), Peru’s largest publicly-traded, precious metals mining company announced the acquisition of 51% of Canteras del Hallazgo S.A.C (49% held by Buenaventura), owner of the Chucapaca project, from Minera Gold Fields Peru S.A. (a subsidiary of Gold Fields Ltd, a globally diversified producer of gold with operations in Australia, Ghana, Peru and South Africa). At the conclusion of this transaction, Buenaventura will control 100% of this project.

Mr. Roque Benavides, Chairman and CEO, stated: “Chucapaca, as an underground mining project located in Peru, offers important potential to continue growing in terms of gold resources and future production. This acquisition fits perfectly with Buenaventura’s expertise to develop underground mining operations that will permit the maximization of shareholders’ value, adding precious metal resources to our portfolio.”

The agreement considers a US$81 million cash payment and a 1.5% net smelter return royalty on gold, silver and copper sales. Buenaventura holds the right of first refusal if Minera Gold Fields Peru S.A decides to sell these royalties.

As a consequence, Buenaventura is taking over 100% ownership of Canteras del Hallazgo S.A.C.

Buenaventura is confident with regards to the strong potential of high grade gold ore in Chucapaca, as is Gold Fields, who requested a royalty payment to participate in the upside.
