Qualified comments: |
(Applies to: discovery and development) Initial exploration was done by Gulf Minerals Canada Ltd. during 1968-1974 and included airborne radiometric survey and some ground follow-up. The company let its exploration permit for the area lapse in 1974. During the same year Canadian Occidental Petroleum Ltd. (CanOxy) carried out an airborne reconnaissance survey over the area, and staked the Wally property, which was later divided into the McClean Lake and Wolly properties. In 1977 airborne magnetic and EM surveys were flown over the property. The first significant discovery was of the Tent Lake zone in 1978 , which led to emphasis on the geophysical methods over the geochemical and radiometric methods. Exploration drilling was guided mainly by the ground electromagnetic survey that located the graphitic zones in the basement 150 m below the Athabasca sandstone. First mineralization at McClean Lake was intersected in drill hole 102 in January of 1979. Furhter drilling during 1979-'81 led to the discovery of sevral closely spaced pods along a strike zone of 1200 m, which is gently covex toward the north. In 1985 Minatco entered into the joint venture with CanOxy and Inco to become the operator of the project. Further exploration during 1987 and 1988 led to the discovery of Pod 5 at McLean Lake North and the highly productive Sue Trend to the east. In 1990 the CanOxy-Inco JV sold out to Minatco, which was subsequently acquired by Cogema Resources Inc. (later changed name to Areva Resources Canada Ltd.). During 1992, Denison Mines Ltd. and OURD Canada Ltd. acquired 22.5 % and 7.5 % interest, respectively, in the McLean Lake Project. Construction of the McLean Lake facility began in 1995.
(Applies to: reserve/resource descriptions) Combined resources of McLean North and South deposits reported by Wallis et al., (1985): 0.351 Mt averaging 1.51 % U, viz., 5297 t U; at cutoff grade of 2.06 % U the resources are 4731 t U in 229.3 kt.
(Applies to: mineralization) There are four distinct facies of mineralization. A sulphide facies, consisting of bravoite-pyrite, coffinite, uraninite with illite, siderite and chalcopyrite (up to 18.5%), is restricted to the interstitial portions of the basal sandstone. An arsenide facies consists of pararammelsbergite plus subordinate nickeline, gersdorfite, and intergrown arsedides-illite. A bleached facies consists of nodular intergrowths of coffinite-pararammelsbergite and illite with subordinate nickeline, gersdorfite and arsenic. The oxide facies ore consists of
coffinite-arsenide-illite nodules which are saturated with hematite±goethite.
(Applies to: miscellaneous comments) Pod dimensions: Pod 1 is 260 m long by 30 to 45 m (98.4 to 147.6 ft) wide by
1.5 to 20 m (4.9 to 65.6 ft) thick. Pod 2 is 152 m (498.7 ft) long by 23 to 30
m (75.5 to 98.5 ft) wide by 1.5 to 19.5 m (4.9 to 64.0 ft) thick. Pod 3 is 110 m (360.9 ft) long by 15 m (49.2 ft) wide by 2.7 to 17 m (8.9 to 55.8 ft)
thick. Pod 4 is 61 m (200.1 ft) long by 15 m (49.2 ft) wide by 1.5 to 11.6 m
(4.9 to 38.1 ft) thick. |
