SUPERIOR — There is no copper being mined from Resolution Copper’s East Plant, several miles beyond the town of Superior. But within Shaft Nos. 9 and 10, work continues in maintaining the vast underground network of pipes, corridors and control systems necessary to keep the mine in ready shape for its eventual purpose.
Shaft No. 9 is left over from the original Magma Mine operation, which shut down in 1982 — the other eight original shafts are now abandoned and were separated with thick concrete barriers from the new operation. Resolution drilled the 10th shaft itself, and the two hoist towers sit atop a hill looking out over Oak Flat. At the time of its completion in 2014, Shaft No. 10 was the deepest in the United States.
