The Duddridge Lake property encompasses approximately 10,000 hectares and is located about 100 km northwest of LaRonge, Saskatchewan. Previous exploration was conducted by a number of companies, including Noranda Exploration Company from 1974 to about 1994. Exploration including combined airborne magnetic and radiometric surveys, rock and soil geochemistry and diamond drilling, outlined a uraniferous boulder train along the west side of Duddridge Lake, which extends over an area of about 100 by 1600 m.

Within the boulder train, typical analysis ranged from 0.1 to 0.2% U3O8, with some exceptional values of up to 9.8% U3O8, 1.6% Cu, 0.2 oz/ton Au, and 7.0 oz/ton Ag. According to the Saskatchewan Government Mineral Deposits Index, in 1977 Thor Explorations indicated a potentially mineable resource of 320,690 tons averaging 1.84 lb/ton U3O8 over 5 feet width and to an average depth of 250 feet. Stuart Fraser P.Geo., completed a Summary Report of the Duddridge Lake Property and calculated a resource of 215,016 tonnes of 2.14 pounds/ton and recommends further exploration to find the source of the uraniferous boulders.
