The O.K. claim (Lot 573s) is 12 kilometres east of Beaverdell and 48 kilometres north of Rock Creek. It lies adjacent to and south of the Ivanhoe claim (Lot 574S). The claims are at approximately 1325 metres elevation, in the Triple Lakes area that forms the headwater basin of Canyon Creek. The area has been extensively logged, resulting in a network of four wheel drive roads. Access to the property is by logging roads from either the main Kettle Valley road to the east or from Beaverdell to the west.
The Ivanhoe-O.K. area is underlain by hornfelsed, late Paleozoic Wallace Formation metasediments that are intruded by hornblende-biotite granodiorite, probably a phase of the middle Jurassic Westkettle batholith (Nelson plutonic suite). Several north-trending shear zones, partially replaced by quartz-sulphide mineralization, cut through the central part of the area. These shears run approximately parallel to a suite of mainly mafic feldspar porphyry dikes.
Locally, a large gossanous zone with quartz veins hosts pyrrhotite and arsenopyrite mineralization. The zone appears to be a contact between granitic rocks and a diabase body (sill or dike) has been shattered and invaded by numerous quartz stringers accompanied by local concentrations of sulphides. The shatter zone is approximately 30 metres wide and strikes south east.
The original target on the Ivanhoe claim is a north-trending quartz vein carrying pyrite, arsenopyrite and minor chalcopyrite; free gold was obtained by panning. The vein is approximately 30 centimetres wide, vertical, and hosted in quartz diorite of the Middle Jurassic Nelson Intrusions that contains stringers of pyrite. It is difficult to define the mineralized zones; there may be two sub-parallel zones that show in two 5-metre pits, or there may be a single faulted zone. In 1902, a sample of the vein assayed 23.8 grams per tonne gold (Property File - Minister of Mines [1904-01-01]: Report of the Minister of Mines 1902 - Horseshoe Mountain Camp).
In 1990, samples of gossanous material yielded less than 300 parts per billion gold, while a grab sample from a 10-centimetre wide quartz vein assayed 1.4 grams per tonne gold (Assessment Report 20122).
In 1994, a grab sample from a 30-centimetre wide quartz vein assayed 23.3 grams per tonne gold and 0.21 per cent copper (Assessment Report 23969).
The O.K. and Ivanhoe claims were located in 1897 and Crown granted to Samuel Larsen and Henry Thoen in 1908. In 1938, S. Peterson shipped 5 tonnes of ore, in which yielded 187 grams of silver and 124 grams of gold.
Development work on the O.K. claim consists of large, shallow open pits or trenches along the shatter zone. In 1902, select samples of quartz and pyrrhotite from the bottom of the main pit (approximately 3.5 metres deep) yielded up to 18.2 grams per tonne gold and averaged approximately 8.3 grams per tonne gold (Property File - Minister of Mines [1902-01-01]: Report of the Minister of Mines 1902 - Horseshoe Mountain Camp). A second pit, approximately 3 metres deep, shows a considerable mass of pyrrhotite. A third pit, approximately 30 metres away, tests the continuity of the mineralized body.
A 1990 soil sampling program by Carmac Resources Ltd. showed that the area is weakly anomalous in arsenic and gold; these anomalies coincide with the pyrrhotite rich gossans on which early development work was focused.
In 1994, Phelps Corporation of Canada, Limited conducted 40-line kilometres of soil sampling in the area. In 1994 and 1995, R.E. Gale sampled and mapped the showings. In 1997, the Ward claims, which include the O.K.-Ivanhoe showings, were optioned by Emjay Enterprises Ltd. Exploration in 1997 through 1999 included considerable sampling, property mapping, a soil geochemical program and ground geophysics.
