Siliceous felsic dikes (Tertiary Sloko-Hyder suite?), with 1 to 3 per cent pyrite and gold up to 2.2 grams per tonne, have intruded Upper Paleozoic sediments and volcanics of the Stikine Assemblage. A quartz-pyrite float boulder of unknown origin yielded 262.29 grams per tonne gold and 391.43 grams per tonne silver (Assessment Report 21842). Fifteen of the thirty-eight talus fine samples returned >40 parts per billion gold concentrated in the area downslope from the quartz-pyrite float boulder and continuous along the contour line for over 200 meters.
The Ban claims were staked in 1988 by Chevron Minerals Ltd and 11 heavy mineral bulk unconsolidated talus & glacial drift samples were collected. The claims were optioned to North American Metals Corp in 1990 and a brief program of prospecting and reconnaissance mapping was conducted 1991.
