The world’s largest high-grade uranium mill.

Located 570 km north of Saskatoon by air, and 220km north of Pinehouse by road, Key Lake lies along the southern rim of the Athabasca Basin. The mill’s main focus is on processing ore from McArthur River Mine which Tron provided construction services on a number of projects at the mill to that effect.
