The specific location of the Treaty Creek occurrence is not known. The showing is reported to be on the north side of Treaty Creek - formerly 20-Mile Creek - a tributary of the Bell-Irving River, about 56 kilometres from the confluence of the Bell-Irving and Nass rivers and approximately 74 kilometres north of the community of Stewart (Minister of Mines Annual Report 1929).

The showing plots in, and is assumed to be hosted by, predominantly clastic sediments of the Middle to Upper Jurassic Bowser Lake Group (Ritchie-Alger assemblage). Refer to Fox (104A 165) and Delta 2 (104A 166) showings located 11 kilometres east for a related geologic environment. Mineralization consisting of chalcopyrite, sphalerite and pyrite is inferred at Treaty Creek from these showings.

In the late fall of 1928, the Treaty Creek group of sixty claims were staked and surveyed on behalf of the Consolidated Mining and Smelting Company of Canada. In July 1929, the company conducted preliminary prospecting on the claims. Values are scattered over a large area and appear to be mainly in gold, silver and copper, although sufficient work has not been done to form a criterion of the possible value of the property (Minister of Mines Annual Report 1929, page C102). In 1930, the claims were examined towards the end of the season by the Consolidated Mining and Smelting Company of Canada and it is understood the values in the mineral occurrence may be too low grade considering the remote location of the claims; the company relinquished its option (Minister of Mines Annual Report 1930, page A110).
