1Heap leach solutions: The separation, or dissolving-out from mined rock, of the soluble uranium constituents by the natural action of percolating a prepared chemical solution through mounded (heaped) rock material. The mounded material usually contains low grade mineralized material and/or waste rock produced from open pit or underground mines. The solutions are collected after percolation is completed and processed to recover the valued components.
Notes:Capacity for 4th Quarter 2015. An operating status of "Operating" indicates the mill usually was producing uranium concentrate at the end of the period.
