The TARA showing is located on the OUTBACK property in the Granby River valley, approximately 25.5 kilometres west-southwest of the village of Edgewood.

The general area is underlain by gneiss of the Proterozoic Monashee Complex. Within the Granby River valley there is a north trending, easterly dipping normal fault, along which andesite of the Eocene Marron Formation (Penticton Group) is preserved. Co-magmatic with the Marron Formation are Eocene Coryell Intrusions which form small isolated intrusions throughout the area. The Coryell Intrusions are largely syenitic in composition, although a quartz-feldspar porphyry, 900 metres to the southeast, may be a calc-alkaline variation. A quartz monzonite intrusion, which outcrops just north of the TARA showing, may be an unnamed Middle Jurassic intrusion.

The TARA showing consists of several widely spaced, beige- coloured and sparsely mineralized chalcedony veins. The veins, which are up to 25 centimetres wide, trend perpendicular to an inferred northwest trending fault. The fault forms the contact between a highly kaolinized intrusive on the southwest, and a propylitized quartz monzonite to the northeast. A 2-metre chip sample of an intensely bleached intrusive, with friable sericite alteration and chalcedony veinlets measuring 3 to 5 centimetres wide, assayed 6.95 grams per tonne gold and 5.7 grams per tonne silver (Assessment Report 21032). It contained a minor amount of pyrite.

The OUTBACK property was staked in 1988-89 by the Canadian Nickel Company Limited (INCO). INCO carried out several field programs of stream sediment sampling, follow-up prospecting, soil sampling and geological mapping in 1989. The gold potential of this area was identified through the use of heavy mineral stream sediment techniques.

In 1990, INCO carried out detailed soil sampling, prospecting, geological mapping and extensive rock sampling on a number of gold- silver occurrences in this area, including the nearby CLIFF (082ENE067), BETH (082ENE068), LEAH (082ENE069), and JANE (082ENE070) occurrences.

In 1991, INCO carried out a 6-hole, 807.1-metre diamond-drill program on the CLIFF (082ENE067) prospect 900 metres to the southeast. A number of drill intersections assayed greater than 0.5 gram per tonne gold (Assessment Report 21916). It is not recorded if additional work was done on the TARA showing at that time.
