"Today, Arizona leads the nation in non-fuel mineral production with over 450 active mines. Arizona continues to be the leader in Copper production, supplying over 70% of the copper production in the USA." -- https://asmi.az.gov/about
I never knew there were so many mines in AZ. Copper I was familiar with, as there were smelter on the north side of the Catalinas, as the smoke would blow in thru Reddington Pass and get called "auto pollution" :-)
