1969-70: airborne Mag and EM survey. Geological, geophysical surveys, prospecting and trenching. Identified py, po and minor cpy at contact between gabbro and mafic metavolcanic rocks. 1973: airborne EM survey. In the winter of 1969-1970, Questor International Surveys Limited conducted an airborne electromagnetic-magnetic surveys of a 466 km2 area between Peak Lake in the west and Highway 17 in the east for a joint venture of Lynx-Canada Exploration Limited with Dejour Mines Limited. At Boyer Lake two long, linear, east-trending conductive zones were detected by the airborne survey, in addition to a number of anomalies picked up on one to three adjacent flight lines. The more southerly of these conductive zones lies approximately coincident with, and along the length of, the gabbro body between Walmsley Lake and Shongwashu Lake. The second zone lies parallel to and about 2 km to the north of the southerly zone, and at its eastern end is approximately coincident with another gabbro body. During the summer of 1970, the geological consulting firm of Derry, Michener and Booth, under contract, carried out a programme of geological mapping, electromagnetic and magnetic surveys, and prospecting and trenching as ground follow-up. According to a report for the consulting firm by J.B. Gordon (supplied to the author by Duncan R. Derry, 1975) pyrite, pyrrhotite, and minor chalcopyrite mineralization was discovered at the sheared northern contact between the southerly gabbro body and mafic metavolcanics. Work in the area was terminated in September 1970, and the claims were allowed to lapse (Duncan R. Derry, personal communication, 1975). As of December 1975, a large part of this area of exploration was held under unpatented claims by Underwood McLellan and Associates Limited (see section on Underwood McLellan and Associates Limited (17) and Underwood McLellan and Associates Limited [1974] (18)). During the same winter, according to the report of J.B. Gordon, Questor International Surveys Limited conducted a similar survey of a 155 km2 area extending some 13 km in a west-northwesterly direction from Wapageisi Lake in the east to the current map-area. The survey was carried out for the Lynx-Canada Exploration Limited-Dejour Mines Limited consortium (Map 2438, back pocket), subsequent to their discovery in 1969 of copper-zinc mineralization east of the map-area near Wapageisi Lake. A number of long linear conductive zones were found to extend westward from Wapageisi Lake into the current map-area about 3 km south of Thundercloud Lake, while an isolated anomaly was recorded on one flight line about 0.8 km south of Thundercloud Lake. As documented by J.B. Gordon, during the summer of 1970, Derry, Michener, and Booth under contract, carried out a second programme of geological mapping, electromagnetic and magnetic surveys, prospecting and trenching as ground follow up to the airborne survey. Conductive zones were more precisely defined. Trenching and stripping disclosed pyrite and pyrrhotite with minor graphite and traces of chalcopyrite on the long zone of conductors, while no significant conductor or evidence of sulphide mineralization was found in association with the isolated airborne anomaly. Work in the area was terminated in late 1970 (Duncan R. Derry, personal communication, 1975). As of December 1975, the ground was open to staking. (R 202, p. 88, 89, 1981)
