The Gar B occurrence is in the southwestern head waters of Angus Creek, at an elevation of approximately 2050 metres.

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, chlorite altered Creston Formation sediments, adjacent to the Big Lead fault, host quartz veins with limonite, sericite, pyrite and visible gold. The veins occur as single veins, up to 3 metres wide, and as swarms of veins over widths of 5 metres.

In 2002, samples yielded from 0.2 to 2.5 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.
