The Prince George occurrence is located near the headwaters of the south fork of the Marmot River, 13.5 kilometres southeast of Stewart.

The showing consists of a quartz vein, up to 1.2 metres wide, striking 059 degrees and dipping 65 degrees northwest. The vein is hosted in granodiorite of the Eocene Hyder pluton (Coast Plutonic Complex), just southwest of the contact with argillite, siltstone and sandstone of the Middle-Upper Jurassic Salmon River Formation (Hazelton Group). The vein contains massive to disseminated pyrite and minor chalcopyrite, galena and sphalerite. Samples of heavily mineralized quartz have assayed up to 66.3 grams per tonne gold and 411 grams per tonne silver (Minister of Mines Annual Report 1921, page 62).

In 1921, the only work done consisted of a few shallow open cuts put in along the bottom of a narrow, steep gulch possibly formed by the erosion of the softer vein material. The exposures are at 1082 metres elevation.

Granby Gold Inc.'s Marmot property, containing the Prince George showing, underwent geological mapping throughout 2013 to 2015. In 2017 the geology was finer tuned by interpretation with regional airborne geophysics and again in 2018 with airborne geophysical survey data.
