The Star 4 occurrence is located on a ridge separating Kingfisher and Danforth creeks, approximately 4 kilometres west of Stony 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.

Mineralization at the Star 4 showing is hosted in calcareous quartzite. The quartzite contains spotty sphalerite and galena along its contacts with calc-silicate gneiss and marble.

In 1974, a chip sample from a trench on the FX 5 zone assayed 0.54 per cent lead and 2.15 per cent zinc across 9.0 metre (Assessment Report 4934).

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.
