The system includes a first lifting machine for excavating and removing overburden from an open pit of a mine. A second lifting machine is provided for excavating and removing valuable material from the open pit. Advantageously, the two machines operating in tandem can result in improved cost and energy efficiency when compared to known mining techniques.
