The PALLAS occurrence is located on the summit of a ridge separating Downton and Cinnamon creeks, at an elevation of approximately 2315 metres. The showing is in the Cayoosh Range, approximately 1.5 kilometres east of Modal Peak and 19 kilometres southwest of Lillooet, B.C.

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 450 metre wide zone of extensive silicification with quartz veined and silicified greenstone hosts gold mineralization. The quartz veins trend 210 degrees with a dip of 75 degrees. Pallas and South Pallas occurrences are north-northwest extensions of the "Raven Trend", associated with a variably listwanite-altered band of greenstone.

In 2012, a sample (R91027) of quartz vein yielded values up to 0.44 gram per tonne gold (Assessment Report 33410).

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. 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.

Reference the RAVEN (Minfile 092JNE056) for more information on area exploration.
