The Gar D (G.S.) occurrence is located at an elevation of approximately 2050 metres on a northwest trending ridge, west of Hellroaring Creek and approximately 3.5 kilometres northwest of Grassy Mountain,

Regionally, the area is underlain by Mesoproterozoic rocks of the Purcell Supergroup, including the lower members up-sequence of the Aldridge, Creston and Kitchener formations. Included within the sedimentary package are primarily sills but also dikes of the gabbroic Moyie Intrusions. The quartzite-dominated turbidites of the Aldridge Formation give way to quartzites and siltstones of the Creston Formation. Granitic intrusives in the region are of two distinct ages and are very dissimilar. Proterozoic pegmatites of the Hellroaring Creek assemblage form sills, dikes, and small stocks, that only intrude the Aldridge Formation. Much younger, likely Cretaceous, stocks such as the Angus Creek stock are composed of granodiorite to quartz monzonite.

Locally, quartz veins with massive pyrite, limonite and visible gold, up to 3 millimetres in size, are hosted by sediments over approximately 100 metres. The veins range from 1 to 15 centimetres in width, strike 20 to 40 degrees and dip steeply to the east.

In 2002, five rock samples (GS-3 to 6) assayed from 2.85 to 19.4 grams per tonne gold (Assessment Report 26963).

In 2001 and 2002, the area was prospected and sampled as the Gar claims by Super Group Holdings.
