which is the equivalent of the Millennium deposit (Roy et al., 2005) in the Athabasca
Basin. The Ace-Fay and Gunnar deposits produced up to 80% of the total U ore (Table
1.1).

The uranium deposits were generally subdivided into pegmatite-type and vein-type
deposits (Beck, 1969; Robinson, 1955; Tremblay, 1972). The latter are further divided into
a small group of complex mineralogy and a larger group of simple mineralogy (Tremblay,
1972; Hoeve, 1978; Kotzer et al., 1995). Deposits of simple mineralogy consist of
pitchblende with lesser amount of pyrite, chalcopyrite, galena, ±nolanite and minor amount
of bornite, covellite, chalcocite, digenite, and native copper (Robinson, 1955). Deposits of
complex mineralogy consist of pitchblende with cobalt-nickel arsenides and sulfides,
cobalt-nickel lead selenides, and native platinum, gold, silver and copper in addition to
