A large number of placer claims were staked on Graham Creek, 12.8 kilometres east of Taku Arm, in 1900.
This placer gold occurrence is the westernmost known placer of the Atlin Camp, probably derived from a nearby lode source (Personal Communication: Ballantyne, B., Geological Survey of Canada, Ottawa, 1988).
Graham Creek flows south into Graham Inlet, some 13 kilometres east of Taku Arm. A large number of claims were staked on the creek in August 1900. The Discovery claim was the only one which produced adequate returns and work was continued on this claim into 1902. The other claims were soon abandoned and subsequently lapsed. In 1903 a small syndicate acquired a number of leases on the creek but were unable to finance the initial cost of a larger scale operation. Further prospecting was done on the creek during the period 1905-1921.
In 2016, Running Dog Resource Ltd and Attunga Holdings Inc. carried out limited mapping and geochemical sampling over the central portion of the Graham property, collecting 5 rock -, 7 silt -, 4 pan concentrate -, and 39 soil samples (Assessment Report 36288). The program was designed to investigate whether the altered Hornblende Feldspar Porphyry of the Windy-Table intrusive suite mapped by Mihalynuk (1999, p.131) was the source of the placer gold in Graham Creek and whether it contains significant base and precious metal mineralization. Results of the 2016 geochemical sampling from the Graham property were subtle, with the exception of a silt sample from Graham Creek which contained 1060 parts per billion gold (Assessment Report 36288). The five float and grab samples collected in 2016 were altered and pyritized but contained low base and precious metal contents. Regional mapping by Mihalynuk (1999) showed a 5 by 1 kilometre pluton of altered feldspar porphyry along Graham Creek, which he assigned to the 70-85 Ma Windy-Table intrusive suite. Mapping in 2016 indicated that the Windy-Table feldspar porphyry actually forms a greater than 200-metre-wide dike which strikes north along Graham Creek for more than 1300 metres.
