    Mining Methods 5 Open pit mines are used to exploit low grade, shallow ore bodies. However, some pits are quite deep – about 1 km. The mining rate is greater than 20,000 tonnes per day (tpd) but is usually much greater. Some pits operate at a rate of more than 100,000 tpd Open pit mining results in two waste streams: waste rock which contains
