The Fraser River (Lytton Bar) placer occurrence is located about 1.6 kilometres north (upriver) from Lytton, British Columbia.
The following quote is from B.C. Government site βMinfileβ- Minfile No. 092ISW 092, current to 1991:
βThe Lytton Bar showing is located in the Lytton Bar black sands on the west side of the Fraser River, 1.6 kilometres north of the Fraser and Thompson rivers confluence.
The black sands are radioactive. A concentrate assayed 0.16 per cent equivalent uranium oxide (Minister of Mines Annual Report 1948). Uraninite is the likely source of radioactivity (Geological Survey of Canada Economic Geology 16).β
Comment by Giles Peatfield regarding the locality:
It is important to stress that while there was placer mining activity at many localities along the Fraser River, this specific location refers to an area of placer mining activity in the 1940βs. It also has no relationship to the well-known Lillooet dredging occurrence, which is about 50 kilometres upriver.
Comments by Giles Peatfield regarding some of the minerals listed:
Most of the minerals listed were identified by Thompson (1954), and a few others by Steacy (1953). It is not completely clear that Steacyβs material was from the same locality, although the minerals listed make this almost certain.
Platinum: Native platinum is common in the placer deposits of the Fraser River.
Sperrylite: Thompson (1954) noted that βThe x-ray powder pattern of these grains is in good agreement with the pattern of sperrylite from the Vermillion mine, near Sudbury, Ontario.β
Thorianite: Thompson (1953) found that βAn x-ray powder photograph is in exact agreement with thorianite (a=5.58 Γ ) from Balagoda, Ceylon. The mineral is probably the uranoan variety because the grains gave a positive uranium bead test.β
Uraninite: This was identified by Steacy (1953), who remarked that βThis occurrence is considered noteworthy because it is, so far as the writer has been able to learn, the first unquestionable identification of uraninite as a detrital mineral.β
