While many copper mines have experienced dwindling ore grades and reserves, a mine in the southwestern 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 spanning 500 acres over an existing stockpile. More than 50 pieces of equipment were deployed 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 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. The construction of three miles of overland conveyor corridors required extremely tight tolerances for positioning the conveyor.
