The Mile 12 occurrence is located in the north eastern head waters of Danforth Creek, approximately 5 kilometres west- north west of the northern end of Mabel Lake.

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.

At the Mile 12 showing, a small outcrop of marble is well mineralized with sphalerite-pyrrhotite-pyrite± galena with hematite and limonite alteration through its entire exposed width of 2 metres.

In 1975, a grab sample from this zone yielded 0.49 per cent lead and 5.3 per cent zinc (Geology in British Columbia 1975, page G29). In 2012, a composite chip sample (CM1-1) assayed 0.830 per cent lead, 10.15 per cent zinc and 5.88 grams per tonne silver over 0.5 metre (Assessment Report 33197).

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 2012, Inexco Mining completed a program of prospecting, rock sampling and a 205.3 line-kilometre airborne electromagnetic survey on the area.
