A new method to harvest copper

• Arizona Republic

The traditional icons of Arizona miners are picks and shovels, but a new project possibly starting up next year in Florence could harvest copper from deep underground without moving a spade of dirt.

Curis Resources Inc., an affiliate of Canadian mining company Hunter Dickinson Inc., plans to mine the copper with hundreds of pumps that send acid underground to dissolve the copper minerals, then suck the liquid and copper back to the surface.
