The East Ridge occurrence is located approximately 16 kilometres south-southeast of Sustut Peak, on the ridge southeast of the A462 occurrence (094D 102) (Assessment Report 4855).

The regional and local geology is similar to that of the A462 occurrence. Fracture surfaces display prominent malachite-staining in a shear zone. The shear zone, 0.61-metre wide, is vertical and trends 106 degrees (Assessment Report 4855). The shear zone contains calcite fracture fillings and cuts Lower Jurassic Telkwa Formation (Hazelton Group) pyroclastics and volcanics.

Rio Tinto Canadian Exploration held the property in the early 1970s as the "A" claim group. A detailed sampling and mapping program, supported by trenching and diamond drilling was conducted. Two drill holes were completed on the A462 occurrence (104D 102). A total of 2498 geochemical samples were taken, mostly soil. In 1974, a combined magnetic and electromagnetic survey totalling 640 kilometres in length was completed over the 'A' claims, including the Pond occurrence area (Assessment Report 4921). Several high conductivity anomalies on the claims were recommended for follow-up.
