Buenaventura Announces Second Quarter 2018 Production and Volume Sold per Metal Results

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 preliminary 2Q18 production and volume sold results as well as full year 2018 operating guidance (100% basis).

Production Comments

Gold Operations

• Orcopampa:

In light of the Company’s strategy to prioritize its De-bottlenecking Program over ore mineral extraction, Buenaventura’s management has made the decision to temporarily reduce annual production guidance for its Orcopampa asset in order to centralize the underground operation. A more detailed explanation will be provided during Buenaventura’s second quarter 2018 results conference call.

• Tambomayo:

Operating at full capacity. 2018 guidance has been confirmed.

• La Zanja:

Second quarter production declined due to a change of its mining contractor. The same contractor used at Tantahuatay, San Martín Contratistas Generales S.A, has been hired as the new contractor at La Zanja, leveraging important synergies between the two mines. 2018 guidance therefore remains unchanged.

• Tantahuatay:

Positive shift in the second quarter production as was previously announced (the first quarter was affected by heavy rains). 2018 guidance has been confirmed.

Silver Operations

• Uchucchacua:

Silver and Lead guidance remains unchanged. Zinc guidance has been increased due to improved grades in the Cachipampa area.

• Julcani:

As was announced in previous quarters, the Julcani operation has been centralized, thereby improving operational efficiency. 2018 guidance has been confirmed.

• Mallay:

Centralizing and stopping the deepening of the mine has achieved positive results. 2018 guidance has been confirmed.

Base Metals Operations

• El Brocal:

The production mix has been modified within El Brocal´s 2018 mining plan. More production will be derived from the polymetallic open pit mine than was previously announced in early 2018. The plan is to smoothly and efficiently transition the underground operation from 8k TPD to 13k TPD. El Brocal´s 2018 annual EBITDA budget will not be affected.
