Description
As at 31 December 2025
Uranium processing facility owned by the MLJV on the eastern edge of the Athabasca Basin about 750 km north of Saskatoon, operated and managed by Orano Canada. It is designed to process high-grade uranium ores using sulphuric acid and hydrogen peroxide leaching with solvent extraction recovery. Site infrastructure includes a sulphuric acid plant, ferric sulphate plant, oxygen plant, a transmission line tied to the provincial grid, a 14 MW back-up diesel plant and site accommodation. A 2016 expansion, paid for entirely by the CLJV, raised the CNSC-licensed annual production from 13.0 to 24.0 million pounds U3O8, enough to process all Cigar Lake output of up to 18.0 million pounds per year with flexibility for other feed. Ore milled was 55,073 in 2025, 58,226 in 2024, 51,866 in 2023, 54,301 in 2022 and 35,409 in 2021; the AIF's unit label for that line is inconsistent with the implied grades, so it is not carried as a row. Denison's 22.5% share of Cigar Lake toll milling proceeds above 215 Mlb U3O8 after July 1, 2016 was sold to Centaurus under the 2017 Ecora Transaction.
