Consolidated Denison Mine, or the Denison Mine is an abandoned uranium mine located approximately 12.5 km north of Elliot Lake, Ontario. The site is bordered north by Quirke Mine and New Quirke Mine; on the east by Panel Mine and Can-Met Mine; and south by Spanish American Mine and Stanrock Mine.[1]
It is owned by Denison Mines Ltd. The site has been rehabilitated and its tailings facility is currently undergoing environmental monitoring by Denison Environmental Services.[1]
The site was the longest continuous operation in the area, from 1957 to 1992, during which time it produced 69 million tonnes of ore.[citation needed]
