Antamina is located in Peru and regulated by Peruvian legislation.
Its four shareholders are leading international mining companies.
In the 1950s the Cerro de Pasco Corporation completed a positive
technical-economic feasibility study on Antamina’s reserves.
However, the political situation in the country at that time
postponed development of the reserves indefinitely. The property
of Antamina returned to State hands under the military government
in 1970s and was held by Minero Perú for more than
15 years. It was privatized in 1996.
The group that won the bidding formed Compañía
Minera Antamina S.A. After two years of exploration, three
years of construction and the most significant investment
in Peruvian mining history, the mining complex began a test
run on May 28th, 2001. Just over five months after beginning
its test run, Antamina achieved commercial production on October
1st, 2001 producing copper and zinc concentrates and other
by-products.
The official inauguration ceremony took place on November
14th, 2001 and was attended by Peruvian President, Dr. Alejandro
Toledo, as well as by diverse authorities and representatives
from Antamina’s partners.
