The Pronto Mine is an historical uranium mine located approximately 20 km south of Elliot Lake, Ontario near Spragge. The site is owned and operated by Rio Algom Ltd,[1] has been rehabilitated and is currently undergoing environmental monitoring.
The mine was in operation from 1956 to 1960,[2] during which time it produced 4,643,835 pounds of U3O8.[3] Upon closure of the mine, the mill was converted to a copper concentrator to process ore from the nearby Pater Mine and operated until 1970.[2]
