Buenaventura Announces Sumitomo Purchase of Five Percent Stake in Yanacocha

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 the purchase by Sumitomo Corporation (“Sumitomo”) of a five percent stake in Minera Yanacocha S.R.L. (“Yanacocha”). Under this transaction between Buenaventura, Newmont and Sumitomo, Sumitomo takes the place of the International Finance Corporation (“IFC”) as a five percent minority shareholder in Yanacocha in exchange for approximately US$48 million.

“We are pleased to welcome Sumitomo as our new partner in Yanacocha and look forward to leveraging Sumitomo’s extensive mining expertise and commitment to high performance mining standards as we develop Yanacocha’s upcoming projects,” said Victor Gobitz, Chief Executive Officer of Buenaventura. He continued, “Newmont and Sumitomo share not only our commitment to safe, profitable and responsible production extension through the Quecher Main and Yanacocha Sulfides project, but also the sustainable economic development of local communities.”

As a result of this transaction, Buenaventura’s total ownership in Yanacocha will return to 43.65% and Newmont’s ownership will return to 51.35%, and Newmont will continue to operate Yanacocha. The transaction is structured as a new share issuance to Sumitomo, with the payment contributing to Yanacocha’s cash balances.

The Quecher Main project was approved in October 2017 and is expected to extend Yanacocha’s oxide mine life to 2027. Quecher Main will also serve as a bridge to future growth options, including the development of Yanacocha’s extensive sulfide deposits. If approved, the sulfides project could extend Yanacocha’s operational mine life through 2039.

Buenaventura also partners with Sumitomo at the Cerro Verde mine in Peru.
