October 9, 2018

LIMA, Peru--(BUSINESS WIRE)--Oct 9, 2018--Compañía 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 preliminary 3Q18 production and volume sold results as well as full year 2018 operating guidance (100% basis).

Production Comments

Gold Operations

Orcopampa: Production is in line with guidance released in 2Q18. The plan is based on the Company’s strategy to prioritize its De-bottlenecking Program over ore mineral extraction, in order to centralize the underground operation. Tambomayo: 2018 gold, silver and zinc production guidance has been increased due to the fact that Tambomayo is now operating at full capacity and it is processing more ore at a level that is exceeding initial estimates. La Zanja: 2018 guidance remains unchanged despite a change in mining contractor during 2Q18. Tantahuatay: 2018 guidance remains unchanged.

Silver Operations

Uchucchacua: Guidance for silver production has been reduced while zinc production guidance has been increased. The plan is to extract more mineral from the Cachipampa area which has higher zinc and lower silver grades than the rest of the mine but is lower cost due to its proximity to underground facilities. Julcani: 2018 guidance has been increased. The Company’s strategy to centralize this operation is achieving results that are exceeding initial estimates. Mallay: 2018 guidance has been maintained. Centralizing and halting the deepening of the mine has achieved positive results.

Base Metals Operations

El Brocal: Copper guidance has been maintained for the underground mine. Lead guidance has been reduced due to the mining sequence in the open pit. Lead grades are expected to increase in 1Q19.
