Southwest Mine for Leach

Southwest Mine for Leach

While most copper mines experienced dwindling ore grades and reserves, this Southwestern mine in the United States has increased its copper production with the discovery of a large primary sulfide deposit below its existing operations.

Ames crews constructed an ore stockpile facility over the top of a previous stockpile, spanning 500 acres. More than 50 pieces of equipment were on site to excavate and haul rock materials.

In addition to earthwork, the project included construction of power line roads and foundations, foundations for two primary power stations, two HDPE solution ponds and a haul road. The work scope integrated crushing and placement of material over liner, and installing 1.4 million linear feet of piping. Construction of three miles of overland conveyor corridors required extremely tight tolerances for positioning the conveyor.
