The Mile 8 occurrence is located on the east side of Kingfisher Creek, approximately 1.8 kilometres north- north west of its junction with Danforth Creek.
The area lies within the Precambrian-Paleozoic(?) Shuswap Metamorphic Complex, a belt of high- grade metamorphic rocks. Rocks on the property comprise a heterogeneous package of granitoid gneiss, augen gneiss, sillimanite-bearing schist and prominent marble and quartzite layers. See Kingfisher (MINFILE 082LNE007) for a detailed regional geology description.
Locally, sphalerite-pyrrhotite-pyrite ± galena mineralization is hosted in marble and is exposed intermittently for a distance of 130 metres along layering strike. The maximum exposed width of the mineralized zone is approximately 2 metres.
In 1975, a grab sample from a small pit assayed 7.7 per cent zinc and 0.7 per cent lead (Geology in British Columbia 1975, page G27).
In 1964, Cominco completed a program of geological mapping and a 50.3 line-kilometre ground magnetic survey on the area as the Bright Star and Kingfisher claims. In 1969, Bright Star Trio Mining completed a program of geological mapping and a 25.7 line-kilometre ground magnetic survey on the area. During 1973 through 1976, Colby Mines completed programs of geological mapping, rock sampling and ground magnetic and electromagnetic surveys on the area as the Black Jack property. In 1994, Kingfisher Marble completed a program of geological mapping, stripping, trenching and bulk sampling. This work centred on industrial marble but a zone of sphalerite mineralization, 1 to 3 metres wide, was encountered in the back of the quarry pit and traced along two trenches, located 12 and 32 metres to the north. This mineralization might be related the Mile 8 occurrence. In 2012, Inexco Mining completed a program of prospecting, rock sampling and a 205.3 line-kilometre airborne electromagnetic survey on the area.
