The historic King William camp is located on Mineral Hill 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 northeast 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.

Workings on the No Surrender showing are situated along strike of the King William vein, between the King William (092ISE110) and Enterprise (092ISE028) mines. Several trenches and bulldozer cuts expose mineralized quartz veins within altered greenstone. The veins pinch and swell up to 50 centimetres in width, swing from north- northeast to northwest orientations and carry variable amounts of pyrite, chalcopyrite, galena and sphalerite. Chip samples assayed up to 3.51 grams per tonne gold and 198.14 grams per tonne silver (Assessment Report 5565).
