Aker Kvaerner awarded Buenaventura’s Poracota Gold Autoclave Project


Aker Kvaerner was awarded the basic engineering package by Compañía de Minas Buenaventura S.A.A. for a gold autoclave for their Poracota mine at the Orcopampa district, in the Province of Castilla, Peru. The project began February 2007 and will run through September 2007.

Compañía de Minas Buenaventura, S.A.A. has contracted Aker Kvaerner Metals, to manage and provide the basic engineering for their Poracota Gold Autoclave Project, a gold ore pressure oxidation facility. Poracota is located 20 kilometers west of Buenaventura’s wholly-owned Orcopampa Mine, at an elevation of approximately 4,000 meters, in the Peruvian Andes. Aker Kvaerner’s scope of work includes the circuit design, equipment sizing, preparation of bid packages, and production of layouts to support the capital and operating cost estimates. The basic engineering package will then be followed by detailed engineering. The front end engineering package will require an estimated time of 33 weeks to complete. Plant capacity is 500 tpd and will use whole ore pressure oxidation of sulphides technology to liberate gold encapsulated in sulphides.

This project is being executed by Aker Kvaerner Metals, Inc., located in Tucson, Arizona, USA.

Compañía de Minas Buenaventura, S.A.A. is a major precious metals producer in Peru and is listed in the New York Stock Exchange (BVN).
