Historically, the Bingham Canyon Mine has come full circle. In the early 1900s, Bingham Canyon led the American metal mining industry away from frontier mining methods and into the modem era. Today, its modernization, productivity and efficiency once again serve as a.Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.The Bootstrap mine.
