The Emulator showing is within the historic King William camp, which is located on Mineral Hill, approximately 6.5 kilometres southwest of the community of Stump Lake.
The Emulator occurrence is within a north trending belt of Upper Triassic intermediate volcanics, volcaniclastics and sediments belonging to the Nicola Group. These greenstones consist of massive, chlorite-epidote altered andesite and basalt, augite porphyry, andesitic flow breccia and tuff, minor interbedded argillite, conglomerate and limestone. Attitudes of tuff horizons and sedimentary bedding suggest that a north plunging axis of a syncline passes through Mineral Hill. Both west and north- east of Stump Lake, the Nicola Group volcanics are intruded by Lower Jurassic granitic batholiths; scattered granodiorite outcrops have been mapped in the vicinity of the camp. Secondary to the north- northeast trending Quilchena and Stump Lake regional faults are numerous smaller faults which form a complex fracture pattern and appear to control alteration and mineralization. Andesitic rocks are bleached, pervasively silicified, pyritic and brecciated. Mineralization occurs in numerous quartz, and less commonly calcite, veins which strike generally to the north and dip steeply eastward.
The Emulator showing comprises an adit and several open cuts that expose a weakly mineralized quartz vein approximately 2 metres wide, striking 335° and dipping 75° east. Diamond drilling intersected quartz veins ranging from 10 to 80 centimetres in width containing pyrite and galena, along with minor amounts of sphalerite and chalcopyrite. One intercept assayed 10.21 grams per tonne gold, 219.39 grams per tonne silver, 0.62 per cent lead, and 0.35 per cent zinc over an 80-centimetre interval (Assessment Report 13152).
The vein is hosted by grey, altered andesitic wallrock containing up to 5 per cent finely disseminated pyrite and occasional blebs of grey sulphides. Sampling returned values of 1.1 grams per tonne gold and 7.8 grams per tonne silver. Trenching further exposed similar sulphide-bearing mineralization within the altered andesitic unit.
