Jan 14, 2020 (Therese Pettigrew) - The Zeus Occurrence is a sulphide-rich zone, at least in part controlled by shearing at the contact between hornblendite and basalt. The zone has been traced over 200 m but there is very little outcrop. At the northeastern end of the zone, and 35 m from the lake shore, a vertical, 2.5 by 1.5 m, cribbed shaft was sunk an estimated 8 m. Dump rocks are very rusty and consist of sheared basalt with abundant pyrrhotite, some pyrite and traces of chalcopyrite. Hopkins (1963) drilled the zone but found no gold. Numerous trenches and pits, and several shafts have also been found on location S82. Hopkins (1963) was able to define 5 north- to northeast-trending veins. Exploration results were summarized by Davies (1978, p. 72-73). The A Vein strikes about 005 degrees, dips vertically, is up 1.5 m wide, and is associated in places with quartz-feldspar porphyry. It consists mainly of quartz, with pyrrhotite, sphalerite, arsenopyrite and pyrite. Gold is apparently erratically distributed, with assays of up to 0.72 oz Au/ton having been reported. Three holes were drilled through the vein, but the core did not contain significant gold. The B Vein is also vertical and strikes about 015 degrees. It consists of a series of quartz veins with pyrrhotite, pyrite and traces of arsenopyrite, chalcopyrite, galena and sphalerite. Assays of up to 0.46 oz Au/ton have been reported from the B Vein. Veins C, D and E are reported to contain only traces of gold (Davies and Smith, 1988). Samples collected by Bond Gold in 1990 at approximately NAD83 UTM Zone 15 356797 m E, 5496969 m N, several samples returned assays of 1.37 to 17.83 g/t Au (Assessment report 52E10SW8227). The map in Assessment report 52E10SW8227, this location is marked with a shaft symbol although it does not correspond to the shaft location in AMIS.
