McClean North — uranium mine

The MLJV's producing deposit, mined by the joint venture's patented SABRE surface-access borehole method. A high-pressure water jet is lowered through a sub-half-metre borehole to erode the mineralised horizon, creating cavities up to four metres in diameter; cuttings are lifted to surface as a slurry and screened, and each mined cavity is backfilled with a cemented mixture. Commercial mining restarted in July 2025 after a 2021 field test recovered approximately 1,500 tonnes of ore grading 4% to 11% U3O8. The resource estimate is supported by the January 2007 McClean North Technical Report and has not been re-estimated for the mining that commenced in 2025, so it does not reflect depletion.
