Doe Run Peru S.R.L. is owned by The Doe Run Company of the US, the world’s largest integrated primary lead producer, which also has excellentfabricating and recycling facilities.The acquisition of the La Oroya metallurgical complex from the Peruvian government in October of 1997 markedThe Doe Run Company’s first venture outside the US and was also the first time the Company's product line was expanded beyond lead to includecopper, silver, zinc, gold and other metals.

Doe Run Peru’s metallurgical complex at La Oroya is located in the Central Andean Highlands of Perú, at 3,775 meters above sea level, and 180 kmnortheast of the city of Lima, Peru. The complex is regarded to be one of the three largest metallurgical operations in the world. This owes to itsoperations diversity and large number of processes for the treatment of polymetallic concentrates with high content of impurities and preciousmetals, which enable it to produce a large variety of refined metals and byproducts.

This metallurgical facility is made up of four integrated circuits: copper, lead, zinc and precious metals. Changes have been recently introduced inthe aforementioned, aimed at improving Doe Run Peru’s processes and operations. At present, The Company produces eleven metals (copper, lead,zinc, silver, bismuth, cadmium and refined indium, gold, selenium powder, tellurium and antimony), as well as eight chemical by-products (sulfuricacid, oleum, sodium bisulfite, copper sulphate, zinc sulphate, zinc powder, arsenic trioxide and silver-zinc concentrate).

Doe Run Peru’s yearly production capacity is: 70,000 tons of refined copper, 120,000 tons of refined lead, 45,400 tons year of refined zinc, 1,200 tonsof refined silver and 2.35 tons of gold bullion.

The Company sells its products to customers in the local market and worldwide. Metals processed at the La Oroya complex are shipped tocompanies in Asia, The United States, South America and Europe.

Doe Run Peru's ultimate objective is to keep its customers supplied with high-quality metal products that are consistently pure, at competitiveprices, and to deliver them on schedule.

The Company’s activities are carried out in a safe and environmentally responsible manner, applying state-of-the-art technology and modernmanagement tools.

The effectiveness of Doe Run Peru’s operations is based on the Company’s great endowment of human knowledge and expertise, the vastexperience of its workers and the use of information technology and real-time communication.

Doe Run Peru works with public consent and strives to maintain good-neighbor relations with the community
