The Taker is located in an area underlain by rocks of the Pennsylvanian Stikine assemblage consisting of maroon tuff and lapilli tuff; ash-flow tuff, deformed tuff and sediments and massive amygdaloidal basalt. These rocks are intruded by Middle to Late Triassic quartz dioritic intrusive rocks, Late Triassic granodiorite and hornblende diorite (commonly foliated) and Paleocene to Eocene quartz feldspar porphyry, alkali granite and alkali feldspar granite of the Sloko-Hyder Plutonic Suite. The Stikine assemblage rocks are in contact to the immediate southeast with a northeast trending fault that separates the Stikine rocks on the northwest from Lower Jurassic Takwahoni Formation (Laberge Group) sedimentary rocks on the southeast, consisting of argillite, greywacke, wacke, conglomerate turbidites. These rocks are overlain by flat lying basalt flows of the Miocene Level Mountain Group and Early Eocene felsic rocks of the Sloko Group.

The tuffs, greenstones and phyllites are quartz-iron carbonate altered, and contain quartz veins and disseminated pyrite. A sample of altered tuff, adjacent to limestone assayed 2.7 grams per tonne gold, over 1.0 per cent arsenic and 0.02 per cent antimony (Assessment Report 12975).

Chevron Canada Resources Limited explored the area for precious metals in 1982. The area of the Tag claims was one of the Chevron properties, the Giver-Taker were staked to cover an extensive alteration zone. Chevron conducted mapping and a program of soil, rock. and silt sampling in 1983 and 1984. See Giver (104K 105) for more complete details of a common work history and bibliography.

In 1992, a BC Geological Survey geological mapping project in the Tatsamenie and Bearskin lakes area resulted in an updated regional geological framework and the discovery of several new showings.
