Bingham Canyon Mine, located near Salt Lake City, is the world's deepest man-made open pit excavation. The mine is 2.75 miles (4,5km) across and 0.75 mile (1,2km) deep. Since mining operations started in 1906, Bingham Canyon Mine has been the granddaddy of all copper mines.
Gold production at the mine continued to be strong throughout 1886, 1887 and 1888 under Waldo’s direction. For example, 5,182 tons of gold ore was mined and processed in 1888 with a total value of $198,666. In 1889, Waldo directed the construction of a new 20-stamp mill that was added to the existing 10-stamp mill.
