The AMA is a non-profit corporation comprised of entities engaged in mining and mineral processing in Arizona. In 2018, AMA member companies produced approximately 68% of the nation's newly-mined copper, along with significant amounts of associated valuable co-products (e.g., gold, silver, selenium, tellurium and molybdenum). Arizona’s hard rock mining industry directly employs approximately 9,800 people and has an estimated direct and indirect impact on the Arizona economy of nearly $10.2 billion. The AMA is the unified voice of responsible, sustainable and safe mining in Arizona. Through our advocacy, we help Arizona continue to be a premier location for mining investment in the U.S.
