The Ant Hill showing is exposed in an old rock pit on the Buff 2 claim, located between Franklin and Gloucester creeks, approximately 62 kilometres northwest of Castlegar.

The oldest rocks in the area are the sedimentary and volcanic rocks of the ‘Franklin Group’, more recently assigned to the Harper Ranch Group (Devonian to Triassic). These rocks occur as pendants and remnants within a variety of younger intrusive rocks, ranging from granodiorite to the syenite, monzonite and pyroxenite of the Averill Complex.

Locally, syenitic rocks and pyroxenite of the Averill Complex are predominant. Franklin Group rocks occur near Franklin Creek, and Valhalla granites are exposed towards the north.

Mineralization consists of pyrite and chalcopyrite hosted in pyroxenite.

In 1987, Placer Dome conducted a field program of geological mapping, soil sampling, and geophysical surveys over the area covered by the Ant 1, 3, and 11 claims. Recent rock exposures on a new logging road were observed in October 2000, which led W.J. Wilkinson to locate the Ant 1 to 13 claims, and to perform fieldwork in June, 2001. Tuxedo Resources Ltd. optioned the claims in July, 2001. The showing has been explored in conjunction with the Ant 2 showing, located 550 metres to the northwest.

In 1987, a rock sample returned values of 24,200 parts per million copper, 95 parts per billion platinum and 650 parts per billion palladium (Assessment Report 17273).
