Geological Details
The showing consists of a mineralized zone located approximately 2 miles (3.2 km) northwest of the north end of Nicholson Lake or 2 miles (3.25 km) east of Horst lake and 30 km (18.6 miles) west of Pelican Narrows. The showing is 8 km (4.9 miles) north northwest of the Hook Zone or SMDI 0336. The showing area is underlain by a narrow band of ease southeast trending meta-volcanics (hornblende-quartz-biotite gneiss with local quartzitic and siliceous hornblende granulite sections, minor greywackes, quartzitic, carbonaceous and chloritic schists occur as well as carbonate-rich sediments and altered andesites). This band of meta-volcanics is flanked by basic to intermediate intrusives and locally cut by pegmatite. This suite of rocks have been subjected to polyphase metamorphism and the metamorphic grade is middle amphibolite facies. A fold closure is located 2.4 km (1.49 miles) west of the zone. The surface projection of the zone is in intermediate meta-volcanics immediately to the east of a lens of felsic volcanics. Coombe and Lorsong speculate that the sericite schist intersected in the drill holes is a sheared extension of the felsic volcanics. The quartz-sericite schist hosted mineralized body is best described as a tabular body that strikes 110° to 115°, dips 55°NW and plunges 45° to 55°W. Delineation drilling has outlined a zone with a strike length of 120 m (393.7 ft), a width of 1.0 to 6.0 m (3.3 to 19.7 ft) and an average true thickness of 4.6 m (15.1 ft). The stratiform zone, which occurs on the overturned limb of a major anticline, is discontinous with narrow widths of high grade ore. The zone proper is surrounded by a 4.6 to 9.1 m (15 to 30 ft) wide halo of fracture fill style lower grade mineralization. The mineralization in the main deposit consists of disseminated to locally massive sulphides that include pyrite, pyrrhotite, sphalerite, chalcopyrite and galena. Intervals containing over 2.5% combined Cu and Zn range in thickness from 0.8 to 6.5 m (2.6 to 21.4 ft). Lower grade disseminated copper and zinc mineralization flank the main zone both on the hanging and foot walls. Several drill holes were completed over the mineralized zone. Chemical assays of the core returned the values listed below.

Exploration History
7/20/1988 The area was first staked in 1965 as the SAD 10 claim and CBS 764 and was later restaked as the SAD 14 claim and CBS 924 by Aage Ulesen for Hudson Bay Exploration and Development Company Limited. In 1965 to 1966, a ground electromagnetic survey was conducted on the property (AF 63M04-0003). this was followed in 1967 to 1968, by the drilling of 27 follow-up anomaly drill holes (SAD Nos. 67-94) totalling 7260 ft (2212.8 m) on the outlined east-trending conductors (AF 63M04-0004 and 0029). Drill hole SAD-74 discovered the HBED or Gee Lake Zn-Cu Zone. Drill holes SAD-75 and 90 to 94 were completed to further delineate the mineralized zone. Chemical analysis of core from the zone gave the values listed above. No further work was recorded on the property and the claims were allowed to lapse. On 25 June 1975, Hudson Bay re-staked the showing area as ML 5169. The property lapsed on 1 May 1978. In the summers of 1985 and 1986, B. Scott (1981) mapped the NTS sheet at a scale of 1:63,630 for the Saskatchewan Geological Survey. In 1983, a Comaplex Resources International (70%) and Wapa Minerals Ltd. (30%) joint venture staked the deposit as CBS 7398 and S-96633 to S-96638. In this year, Wapa Minerals completed reconnaissance geological mapping and lake sediment sampling over the property (AF 63M03-0029). Between 1984 and 1988, the partners completed ground geophysical surveys over the deposit (AF 63M04-0026). In the summer of 1988, B. Slimmon geologically mapped the showing area at a scale of 1:20,000 for the Saskatchewan Geological Survey. In 1990, Comaplex Resources Ltd (37.5%), Taiga Resources (37.5%) and W. Dunlop completed ground VLF-EM and magnetic surveys over the showing area (AF 63M04-0027). In 1991, a partnership involving Ora Resources Inc. (5%)-Comaplex Minerals Corporation (70%)-Wapa Minerals Ltd (25%) completed detailed geological mapping and ground a VLF-EM survey over the showing (AF 63M04-0028).
