The Kok occurrence is situated on the south side of Busk Creek within the Kokanee Creek property, on the east side of Kokanee Creek, north of the West Arm of Kootenay Lake, approximately 1.6 kilometres northeast of Crescent Bay and 19 kilometres east of Nelson.
The area is underlain by Late Precambrian to Cretaceous volcanic and sedimentary rocks. Jurassic to Cretaceous Nelson and Valhalla intrusives and Tertiary alkalic plutons intrude the volcanic and sedimentary units. The region has been metamorphosed to lower to middle greenschist facies with associated chlorite, epidote, biotite hornfels and minor amphibole. Contact metamorphism related to Nelson and later intrusives occurs in both the volcanics and sediments. Regional structure is dominated by a series of north-northwest–trending tight folds and shears.
In the Kokanee Creek area, Slocan Group basal slates and phyllites with lesser fine-grained quartzite and limestone beds are overlain by well-bedded, arenaceous quartzite argillites with local impure quartzite and limestone. The top of the argillite section is marked by tuffaceous lava beds, likely related to early Rossland Group volcanism. Jurassic Nelson intrusives consist of porphyritic granite, granodiorite, diorite, quartz diorite, monzonite and hornblende syenite. Several smaller alkaline plugs belong to the Tertiary (Eocene) Coryell Batholith.
The claim area is underlain by a metasedimentary roof pendant remnant within the Middle Jurassic Nelson Batholith. The roof pendant is predominantly composed of argillic siltstone (siltite) and biotite schist mixed with Nelson paragneiss. Siltstones are exposed along the Lower Kokanee Creek Road and the Upper Busk Creek Road. Large rusty quartz veins intrude host sedimentary rocks. Some of the veins contain muscovite and form minor stockworks. Sulphide mineralization on the property includes coarse-grained euhedral galena, coarse-grained euhedral pyrite cubes and associated pseudomorphs, in addition to fine-grained disseminated arsenopyrite.
The main Kok showing consists of irregular quartz veinlets carrying pyrrhotite, pyrite, sphalerite and galena in a fine-grained to porphyritic granite rock.
In 1979, Anton Nyhuis staked the Big ‘M’ claim group on the south side of Busk Creek. Nyhuis prospected the claims and collected six soil samples and one rock sample before selling the claims to Robin W. Pearson in January 1980. That summer, Pearson Gallagher Limited conducted a magnetometer survey over the area of the Kok showing.
In 1996, the Home claims were staked over the area by Eagle Plains Resources Limited and Miner River Resources Limited as part of the Kokanee Creek property. From 1996 to 1997, Eagle Plains Resources completed silt and soil geochemical surveying, diamond drilling, chip sampling and 3.5 kilometres of horizontal loop electromagnetic geophysical surveying. In total, 445 metres of NQ diamond drilling was completed in five holes situated south of Busk Creek and east of Kokanee Creek. Drillholes KC97-03 to KC97-05 were completed along Upper Busk Creek Road to the south of the Kok showing. All three holes intersected zones of mineralization.
An airborne electromagnetic geophysical survey was flown over the property by Eagle Plains Resources in 2004. Field work that year included geological mapping and soil (125 samples) and silt (15 samples) geochemical surveying.
One rock sample collected along a road immediately south of the Kok showing returned trace gold and 24 grams per tonne silver (Assessment Report 8725, page 10).
Drillhole KC97-03 encountered 0.4 metre of 0.775 gram per tonne gold and 45.2 grams per tonne silver associated with a rusty, quartz-flooded, weakly gneissic intrusive and a 0.1-metre band of quartz-flooded mylonitic siltite with 0.12 per cent cadmium and 5.96 per cent zinc (Assessment Report 25105). Drillhole KC97-04 encountered 1 metre of siltite with strong, pervasive, fine purple-brown biotite flooding returning 33.43 grams per tonne silver, 0.58 per cent lead and 0.9 per cent zinc (Assessment Report 25105, page 15). The anomalous metal values in KC97-04 were associated with finely disseminated pyrrhotite and sphalerite.
