There are probably a lot of mine tailing piles near the mines near Globe.  I don't know if they are private or public, so you may need to pay attention to signs or ask permission.  If you know of a specific location consider adding it separately from this post. 

Here are some mentions from the source: "(2) area great copper mines: (a) Buffalo and Continental Mines, and (b)
Dominion Mine: rich assortment of Copper minerals; (5) W 6½ mi., at Keystone and Live Oak Mines: Chrysocolla, chrysocolla-stained
calcedony, rock crystal and other Copper minerals"
