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.

As a strong mid-tier copper producer focused on the Americas, it’s our mission to create more value for our people, investors, and communities by responsibly producing copper to meet growing global demand.

Cal-Chem Metals was founded in 1980 as a trading company for copper oxide and related materials. In 1996, the company began operations in Arizona, manufacturing copper oxide for a single customer. That business grew until Cal-Chem needed a larger facility and moved to their current location in Globe, Arizona in 1998. Cal-Chem Metals works with Clients across North America on copper recovery projects. These copper reclamation projects include copper slag recovery, copper mud recovery and rod mill scale/filter paper recovery. Cal-Chem Metals can also develop specific copper oxide for any of our client’s applications.
