The O.K. prospect is located on the south flank of Thoen Mountain and has been tested by several trenches and a 13-metre long adit.

The host rocks are Middle Jurassic to Lower Cretaceous Bowser Lake Group tuffaceous sandstones and other clastic sedimentary rocks. These are intruded by dikes and sills of granodiorite related to the Mount Thoen stock which is located to the northwest. The Mount Thoen stock is one of the Late Cretaceous Bulkley Intrusions.

Mineralization consists of narrow veins containing galena, sphalerite, tetrahedrite and pyrite in a gangue of quartz and carbonate. A 25-centimetre wide sample from a vein above the adit assayed 2743.2 grams per tonne silver, 36 per cent lead and 0.7 gram per tonne gold (Minister of Mines Annual Report 1921, page 100). The vein ranges up to 60 centimetres in width. Other veins in the area are 5 to 15 centimetres in width. The mineralization exposed in the adit is highly oxidized and no fresh sulphides remain. The veins are parallel to bedding which strikes 040 degrees and dips 25 degrees northwest into the mountain.

WORK HISTORY

The 0.K. group of claims was owned by Henry Thoen and partner in the 1920s. Development work consists of a 12-metre crosscut adit and surface strippings.

In 1980, Short Staun Minerals Corporation acquired the OK claim group which covered all of the known mineralization in the basins around the peak of Mount Thoen with the exception of the True Fissure workings area. Arctex Engineering Services was commissioned to map the OK claims and sample any mineralization found on them. The veins on the surface are badly leached out containing only iron oxides. Sample T-14-1 shows the location of the old OK workings (Geology and Rock Location map, Assessment Report 8771).

In 1984, Locke B. Goldsmith conducted a brief program of soil sampling on his OK claims II and III). Forty-three soil samples were collected near the southeast corner of the OK III claim, about 1.7 kilometres southeast of the O.K. occurrence that was covered by the Goldsmith claims.

From 2005 to 2013 the Daniel Merkley and William Merkley were owners of four OK claims. In 2013, two samples were taken near the O.K. workings by the Merkleys. It was reported at the time that there appeared to have been 2 veins which were mined by the short OK adit, one visible in outcrop at the exterior of the adit and the other visible on the walls of the adit from its interior.
