The Eastern Star occurrence is located on the Sooke River, near its junction with Macdonald Creek.

The occurrence is one of a number of talc showings that occur on or adjacent to the Leech River fault which separates Jurassic to Cretaceous Leech River metasediments from Eocene Metchosin Volcanics. The talc occurs in shear zones within slates and schists of the Leech River Complex (Formation). Its abundance in this area is probably related to the latest movement on the Leech River fault (Massey, Personal Communication; see 092B 031 - Invereck). The showings are also of interest because of the native gold which is sometimes found in the gouge material lying between the talc and the slate country rock.

On the Eastern Star showing, a body of talc 2.3 metres long was exposed in an opencut. The footwall had not yet been exposed (Minister of Mines Annual Report 1924, page 256).

In 1976, a program of trenching, rock sampling and four diamond drill holes, totalling 100 metres, were completed on the area as the Skijump claim. In 1978 and 1979, programs of trenching, an 8.5 metre shaft and nine diamond drill holes, totalling 278.9 metres, were completed on the area as the East, South, North and West claims. In 1985, the area was prospected as the Aura 1-2 claims.
