Point Location Description: Point plotted on OBM topo map from information contained in Assessment File T-3338.
Location Method: Based on Assessment
Access Description: Access to northeastern and central Tully Twp is via the Ice Chest Lake road (gravel) to a point approximately 1 Km north of Sawmill Lake. From there the OBM map indicates a road leading west to the west side of the Buskegau River. Access to the remainder of the area is via bush trails.
Exploration activity by Homestake in 1991 focussed on a systematic follow-up of the gold intersection reported in DDH TU-1-3-70 by Hollinger Mines, and subsequent gold values by Esso Minerals (see MDI 42A14SE00029). Homestake DDH T91-02 was drilled approximately 100 metres to the southeast of the discovery hole and intersected weakly anomalous gold values which returned a weighted average grade of 253 ppb Au / 7.4 metres (97.6-105.0 m). These values were hosted by what the Summary Log describes as Graphitic Mud/Argillite (Fault), Intensely Brecciated, Fe Carb Altered Rock (Mafic Volcanics), and a Mineralized, Strongly Sil-Carb Altered Intermediate Mafic Volcanic. Additional notations of strong sil-carb-fuc alteration were present further up-hole, but contained no significant gold values.
