    Minerals, in the form of copper ore, were first discovered in Bingham Canyon in 1848 by two brothers, Sanford and Thomas Bingham, sons of Erastus Bingham, latter-day saint pioneers of September 1847, who grazed their cattle there. They reported their find to their leader, Brigham Young, who advised against pursuing mining operations because the survival and establishment of settlements was of paramount importance at that time. The brothers applied themselves to that purpose as directed and di

    Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburdenis relatively thin or the
