McClean Lake — uranium mine

22.50%-held joint venture on the eastern edge of the Athabasca Basin approximately 750 km north of Saskatoon, operated and managed by Orano Canada. The MLJV owns the McClean Lake mill and a group of deposits including Sue D, Sue E, Sue F and McClean North. In January 2024 the MLJV approved a restart of uranium mining using its patented SABRE surface-access borehole method at McClean North, and commercial production was announced in July 2025: 4,392 tonnes of high-grade ore extracted on a 100% basis (Denison's share 988 tonnes) yielding 648,558 lb U3O8 of finished product (Denison's share 145,926 lb) at an operating cash cost of about $36/lb U3O8. Orano holds a 10-year CNSC licence to June 30, 2027 covering McClean and Midwest, authorising SABRE mining of the McClean North deposits and care and maintenance at Midwest.
