Resolution Copper Mine
In 1995 a high-grade copper deposit was intersected by drill holes from the underground workings of the old Magma mine three miles east of Superior, Arizona. The deposit, possibly the largest copper deposit in North America, lies deeply buried a mile below the surface under post-mineral rocks. The photo shows the historic Number 9 headframe to the left of the modern Number 10 used to drill the Resolution deposit.
