ABSTRACT A method of open cut mining comprises the steps of: driving tunnels into one or more seams of minerals to be mined or in the surrounding rock sinking or raising holes or shafts between the surface and the tunnels. A bulk transport or conveyor system is installed in the tunnels to remove material from the bottom of the holes or shafts to the surface. The overburden remote from the holes is removed such that the minerals are accessible on the surface adjacent to the holes, and the minerals are deposited into the holes such that they can be transported by the bulk transporter conveyor system to a storage area external of the pit.
