Summary
Subsidence is a slow and gradual process that is predicted, closely monitored and controlled. Mining will start from a point away from Apache Leap, and after 40 years of block-cave mining, projections are that the subsidence zone will be at its deepest (1,100 feet) but will still be more than 1,100 feet from the Leap after mining has ceased.
