The T-Bird occurrence is located east of Okay Mountain, approximately 2.3 kilometres north of Okay Lake.

The area is underlain by Paleozoic Sicker Group volcanic rocks and sediments in fault contact with Upper Triassic Karmutsen Formation (Vancouver Group) andesites. Cretaceous sediments of the Nanaimo Group unconformably overlies these rocks.

The occurrence covers faulted north-northwest trending contact zones between Karmutsen Formation basalt and Sicker Group rocks comprised of interbedded massive argillites, cherty argillite, chert and andesitic tuffs. The Sicker Group rocks may be correlative with rocks of the Devonian McLaughlin Ridge Formation (Cowichan uplift only). The argillite units are generally thick but the green-brown andesitic tuff unit is over 20 metres thick and hosts the T-Bird showing. This sequence strikes north-northwest and dips approximately 75 degrees east. At the showing, a number of quartz veins up to 30 centimetres wide, fill tension fractures that are generally normal to the bedding of the andesitic tuff unit. The veins are weakly mineralized with pyrite at surface but contain massive pyrite about a metre below the surface.

In 1981, Manny Consul. completed a program of soil sampling on the Nanoose claim. In 1986, Youngman Oil and Gas Corp. completed a program of rock sampling and a ground electromagnetic survey. In 1987 through 1991, Goldbank Ventures explored the area as the Bon 1 claim. Programs of geological mapping, geochemical sampling and trenching were completed. A grab sample assayed 2.22 grams per tonne gold (Assessment Report 18875).

One hundred metres south of the T-Bird showing, the Hayes vein showing consists of a pyritic, fractured chert hosting a set of 1.3 to 5 centimetre wide quartz veins cross-cutting argillite. Grab samples assayed 7.26 grams per tonne gold and 5.82 grams per tonne silver from a pyritic, fractured chert unit and 64.10 grams per tonne gold and 29.82 grams per tonne silver from (Assessment Report 18875). A channel sample from the zone returned a weighted average of 6.3 grams per tonne gold over 3.3 metres, including 1.2 metres yielding 15.4 grams per tonne gold (Assessment Report 20028).

In 1994, the former Songbird claims were staked as the Bon Group by B. Donovan. A program of prospecting was completed in 1997. In 2005 and 2006, D.J. McLelland completed programs of prospecting in the area.
