An in situ method of mining is disclosed. In one non-limiting embodiment, the method includes: defining an ore volume; drilling a large number of vertical boreholes; forming lateral boreholes from at least some of the vertical boreholes; transporting the ore cut during drilling of the vertical and lateral boreholes to a surface location; and separating the ore received at the surface from other materials. Additional ore may be extracted fracturing and/or leaching the formation surrounding the drilled boreholes. The residual ore at the surface may be disposed by pumping it into already drilled boreholes or underground storage facilities.
