Resolution Copper is providing some additional information related to the nature and characteristics of underground hard rock mineral deposits and how the characteristics of the deposits define the mining methods that are used with a particular focus on selective methods such as cut and fill and unselective methods such as block caving as the two methods that have been used by mines in and around the Copper Triangle for the last century.

Thumbnail image of DRAFT - Subsidence Monitoring Plan cover

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.
