Update from Resolution Copper Mine Project
The Resolution Copper deposit ranges from 5,000 to 7,000 ft (1,500 to 2,130 m) below the surface.
The deposit’s average grade is estimated at 1.5% copper 1. The proposed underground mine is expected to become the largest copper mine in North America, supplying copper that’s critical to everyday life.
Our aim is that the mine will produce as much as 40 billion pounds of copper over 40 years
