The site is bordered north by [Quirke Mine](/source/Quirke_Mine) and New Quirke Mine; on the east by [Panel Mine](/source/Panel_Mine) and [Can-Met Mine](/source/Can-Met_Mine); and south by [Spanish American Mine](/source/Spanish_American_Mine) and [Stanrock Mine](/source/Stanrock_Mine).[1] It is owned by [Denison Mines Ltd.](/source/Denison_Mines) 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] ## History The site was discovered in 1953, by F. H. Jowsey, A. W. Stollery who sold his stake to Consolidated Denison Mines Limited in 1954.[1] Geological surveys commenced in July 1954 followed by diamond drilling.[1] Two shafts were started in 1955 one to 1,856 feet and another to 2,766 feet that wasn't completed until 1957.[1] In 1957 reserves were estimated at 136,787,400 tons graded at 2.78 pounds of [U308](/source/Uranium_trioxide) per ton.[1] Ore processing facilities were built, capable to processing 5,700 to 6,000 tons per day.[1] The site has two tailings management areas that includes 64 million tons of tailings under water.[2] The site was decommissioned in 1997.[2] ## Other mines in the area - [Stanleigh Mine](/source/Stanleigh_Mine) - [Spanish American Mine](/source/Spanish_American_Mine) - [Can-Met Mine](/source/Can-Met_Mine) - [Milliken Mine](/source/Milliken_Mine) - [Panel Mine](/source/Panel_Mine) - [Stanrock Mine](/source/Stanrock_Mine) - [Quirke Mine](/source/Quirke_Mine)(s) - [Pronto Mine](/source/Pronto_Mine) - [Buckles Mine](/source/Buckles_Mine) - [Lacnor Mine](/source/Lacnor_Mine) - [Nordic Mine](/source/Nordic_Mine) ## See also - [Quartz-pebble conglomerate deposits](/source/Uranium_ore_deposits#Quartz-pebble_conglomerate_deposits) - [Uranium mining](/source/Uranium_mining) - [List of uranium mines](/source/List_of_uranium_mines) - [List of mines in Ontario](/source/List_of_mines_in_Ontario) ## References 1.
