The TO 2 showing, a quartz vein in porphyritic andesite, is located 1.75 kilometres south of Toodoggone Lake and 1.25 kilometres northeast of the Mount Graves prospect (094E 087) (Assessment Report 9279). Smithers is 290 kilometres to the south.

The TO 2 showing is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. These Takla rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation, Hazelton Group.

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The TO 2 showing is located within a belt of regionally undivided volcanics and associated sediments of the Toodoggone Formation. On a property scale, these rocks have been subdivided into the following units. The main lithology underlying the TO 2 showing is a plagioclase porphyritic andesite with epidote and clay alteration of plagioclase phenocrysts. Narrow veinlets of epidote are common and outcrops near the contact with monzonite contain moderate pyrite. Other lithologies evident in the area include basalt, dacite, and lithic tuff. Tuffs strike north-northwest and dip 35 to 45 degrees. Narrow quartz veins (2 to 3 centimetres wide) containing pyrite are common in dacite.

In 1980, Du Pont of Canada Exploration Limited staked the TO claim. Ten stream sediment samples and 3 rock samples were collected which resulted in the discovery of the TO showing.

A 10-centimetre wide quartz vein comprising the TO 2 showing is hosted in lithic tuff and contains about 10 per cent combined pyrite, chalcopyrite, sphalerite and galena. Sample 8018D from this vein analysed 0.068 gram per tonne gold, 6.51 grams per tonne silver, 0.52 per cent zinc, 0.276 per cent copper and 0.10 per cent lead (Assessment Report 9279).

In 1981, a rock sample (SC-1-81-3) of quartz vein with chalcopyrite, taken approximately 600 metres to the north and at an elevation of 1400 metres, yielded 0.18 gram per tonne gold, 4.3 grams per tonne silver and 0.080 per cent copper (Assessment Report 9502).

Work was done in the TO 2 showing area by Mt. Graves Explorations Inc from 1985-1987 by Vetta Ventures in 1996 and Stealth Minerals in 2003 and 2004.

In 2003, a float sample (133989) of chalcopyrite-malachite–bearing quartz vein boulder, taken in the vicinity of the 1981 sample to the north, yielded 1.10 grams per tonne gold, 18.6 grams per tonne silver, 0.103 per cent copper and 0.108 per cent zinc (Assessment Report 27441).
