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, has been rehabilitated and is currently undergoing environmental monitoring.

The mine was in operation from 1956 to 1960,[1] during which time it produced 2.3 million tons of ore.[citation needed] 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.[1]


The Pronto deposit was the first uranium deposit discovered in the Algoma region.[2]
