a drilled well casing positioned substantially vertically within a heap or pile, the drilled well casing comprising an open top, an open bottom, and at least one perforation zone comprising a plurality of perforations along a vertical section of the drilled well casing;

a pressurized fluid;

a pipe positioned within the drilled well casing, the pipe configured to receive the pressurized fluid;

a first isolation mechanism configured to seal the drilled well casing above the at least one perforation zone; and

a control valve configured to selectively direct the pressurized fluid into an interior of the heap or pile through the at least one perforation zone or the at least one perforation zone and the open bottom,

wherein the control valve is configured to close or employ a second isolation mechanism to seal the drilled well casing below the at least one perforation zone to isolate a first flow of the pressurized fluid through perforations among the plurality of perforations of the at least one perforation zone,

wherein the control valve is further configured to open or not employ the second isolation mechanism to direct a second flow of the pressurized fluid through the open bottom, and

wherein the first flow fluidizes materials within an interior of the heap or pile and creates a plurality of substantially horizontal fluid channels in the materials in the interior of the heap or pile, and

wherein the second flow creates a substantially vertical fluid channel within the interior of the heap or pile.
