Pinto Valley is currently the only operating mill located in the historic Globe-Miami mining district of Arizona, one of the oldest and most productive mining districts in the United States. Since its first recorded production in 1975, Pinto Valley has produced more than four billion pounds of copper, including 0.5 billion pounds of copper cathode. Capstone acquired Pinto Valley from BHP Billiton in October 2013 and is currently the second-largest employer in the district contributing over $270 million annually to Arizona’s economy.
Capstone continues to optimize Pinto Valley for higher copper prices.
