The SOUTH DOWNTON occurrence is located in the Cayoosh Range on the south side of Downton Creek, at an elevation of approximately 1310 metres. The showing is approximately 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 quartz veined listwanite hosts gold values. In 2012, a sample (R91019) from a 1 metre wide quartz veined listwanite assayed 5.95 grams per tonne gold (Assessment Report 33410).

The area is approximately 700 metres south-southeast of the Raven (MINFILE 092JNE056) prospect and has been explored in conjunction with the same. During 1990 through 1993, Reese River Resources completed programs of trenching, rock and soil sampling, geological mapping and 12 diamond drill holes totaling 480.7 metres. During 2008 through 2017, 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.

In 2022, Red Eye Resources Ltd. conducted a small soil and rock sampling program in the vicinity of the South Downton occurrence, In 2023 Dinero Ventures Ltd. conducted a trenching and rock sampling program over some of the showings in the area.
