The Gold Star silt-soil geochemical anomaly is located on the eastern side of Harrison Lake, approximately 4.5 kilometres east of the Doctors Point (MINFILE 092HNW071) occurrence.

Regionally, the area is situated on or close to the Harrison Lake shear zone, a right-lateral transcurrent fault that splays northward into an imbricate fan of high-angle brittle faults. In part, it passes along, and parallel to Harrison Lake, separating the Early and Middle Jurassic Harrison Lake Formation and Cretaceous Fire Lake Group on the west side of the lake, from the Cretaceous Slollicum schist on the east side.

Locally, highly metamorphosed orthogneiss and paragneiss, which include bands of schist and recognizable shale horizons, host pyrite and lesser chalcopyrite where it tends to follow the schistosity in streaks. Quartz veins and pods are present through the schists.

In 1983, Gulf Titanium staked the Gold Star claims and completed a program of geochemical sampling. Later in 1983, Equus Petroleum acquired the property and completed a program of geological mapping and soil and silt sampling. This work resulted in a gold, copper, arsenic and molybdenum anomaly (Assessment Report 12384). In 1985, Equus completed a program of geochemical sampling and a magnetometer survey.

In 1983, geochemical sampling of soil and silt returned up to 690 parts per billion gold, 656 parts per million copper, 800 parts per million arsenic and 114 parts per million molybdenum (Assessment Report 12384).
