1. Heap 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.
- = No data reported.
Notes: Capacity for the 2nd quarter of 2019. An operating status of operating indicates the mill usually was producing uranium concentrate at the end of the period.
