Under the terms of the agreement Newmont will acquire Buenaventura’s interest for $300 million plus contingent payments of up to $100 million, in part tied to higher metal prices. Concurrently, Newmont will transfer its ownership interest in the La Zanja joint venture to Buenaventura in exchange for royalties on any future production from the La Zanja operation. Newmont will also contribute $45 million to Buenaventura to cover future closure costs at La Zanja.
