The Spahats East tungsten occurrence is located on the east face of Raft Mountain.

The area is underlain by quartz-feldspar-biotite schist, quartz-felspar gneisses, quartz-mica schists and hornblende-quartz-feldspar schists of the Proterozoic to Paleozoic Shuswap Assemblage. These have a general north east -striking schistosity with a south east dip ranging from 45 to 60 degrees. Locally, isoclinal folding is present.

Locally, 0.5 to 1.5 metre bands of skarn zone host scheelite mineralization. The skarn zone consists of garnet and actinolite with lesser amounts of pyroxene, idocrase and wollastinite. In 1982, a sample assayed 0.26 per cent tungsten trioxide over 2 metres. Previous float grab samples from the area, collected in 1979, assayed up to 1.32 per cent tungsten trioxide (S. Enns, A. Winkler [1983-02-01]: Final Report 1982 Geochemical Survey Kootenay Arc Tungsten Project, Kidd Creek Mines).

In 1979, Texasgulf completed a program of stream sampling and prospecting on the area. In 1982 and 1983, Kidd Creek Mines completed regional geochemical sampling and prospecting on the area as a part of the Kootenay Arc Tungsten project.
