About McArthur River Uranium Mine
The largest high-grade uranium mine in the world. Located in the Athabasca Basin of Saskatchewan. Ore grades run about 100 times richer than typical uranium mines. Groundwater is frozen into impermeable walls before mining. Remote mining methods limit worker exposure to radiation. Was the top uranium producer in the world for years.
