The Black Raven occurrence is located south of Downton Creek, on a logging road at an elevation of approximately 1260 metres.

The region is underlain by the Mississippian to Jurassic Bridge River Complex (Group), which are exposed along a broad, complex antiformal structure that plunges northwest. The group consists mainly of a thick sequence of bedded chert, chert argillite and argillite intercalated with altered basaltic flows (greenstone) and minor limestone. The greenstone is altered to listwanite (quartz-carbonate alteration) and flooded by pyrite. Most of the Bridge River Group exhibits pumpellyite-prehnite metamorphic grade.

Locally, a sheared and contorted argillite hosts pyrite, pyrrhotite and magnetite mineralization.

In 2012, a sample (R91003) assayed 0.11 gram per tonne gold (Assessment Report 33410). A strong soil gold anomaly occurs on the former Sam claim to the east (Assessment Report 26087).

The area has been explored in conjunction with the Raven (MINFILE 092JNE056) occurrence. During 1990 through 1993, Reese River Resources completed programs of trenching, rock and soil sampling, geological mapping and 12 diamond drill holes totalling 480.7 metres. In 2000, the area was staked and prospected by R. Polischuk. During 2008 through 2012, Cresval Capital completed programs of rock, silt and soil sampling, geological mapping, an orthophoto interpretation and ground magnetic and electromagnetic surveys on the area as the New Raven property.
