Latitude & Longitude (WGS84): 58° 6' 0'' North , 153° 20' 24'' West
Latitude & Longitude (decimal): 58.10000,-153.34000
Köppen climate type:Dfc : Subarctic climate


Location: This site is the beach at Drivers Bay on the northwest coast of Raspberry Island (Cobb, 1972, MF 468, locality 2; Cobb, 1973, Bulletin 1374, figure 11, locality 6; MacKevett and Holloway, 1977, locality 2). The beach is approximately 1/2 mile long and probably has been placered at various locations.
Geology: This site was first mentioned by Brooks (1915, p. 47) who reported that low grade placer gold had been found on Raspberry Island. The latest reported activity took place in 1935. The deposition of beach placer gold is thought to have resulted from the reworking of coastal deposits of glacial gravels and tills.
Workings: In 1935 it was reported that 2 or 3 men were prospecting and mining here. Some drilling was done on valley gravels located between Raspberry Beach and Onion Bay to test the viability of a dredge operation (Capps, 1937, p. 172). Results were apparently poor and the drill project was abandoned.
Age: Quaternary
Production: A small amount of gold was produced but no records are available.

Commodities (Major) - Au
Development Status: Yes; small
Deposit Model: Gold placer (Cox and Singer, 1986; model 39a).
