The Gusty showing is located approximately 75 kilometres southeast of Burns Lake on the north shore of Intata Reach.

The region is within the Intermontane Belt, underlain dominantly by Lower to Middle Jurassic volcanic and sedimentary rocks of the Hazelton Group. These assemblages are overlain by the Upper Cretaceous to Lower Tertiary Ootsa Lake Group and Miocene plateau basalt. Intruding Lower Jurassic rocks of the Hazelton Group in the northeastern part of the map sheet is a belt of granodiorite, diorite, and quartz diorite plutons of the Lower Jurassic Topley intrusive suite. Felsic plutons of probable Cretaceous age intrude both Lower and Middle Jurassic Hazelton strata.

The claims are dominantly underlain by rocks of the Ootsa Lake Group. These comprise rhyolite, dacite, felsic tuffs, ash tuffs, lapilli tuffs with minor basalt and andesite.

Gold and silver mineralization on the Barb-Gusty claim group is associated with north to northeast trending fracture/shear zones. These zones contain translucent to milky white quartz and/or dark grey to black cherty chalcedonic quartz. Stockwork quartz or intense silica replacement zones rarely exceed several metres in width. Significant mineralization occurs in close proximity to major northeast trending fault lineaments.

The Gusty showing, which covers a 125 by 175 metre area, consists of numerous, subparallel, north-northeast trending fracture sets. The discovery subcrop consists of cross-cutting 1 to 5 millimetre wide silica veinlets hosted in a platy, siliceous, flow-banded rhyolite. Mineralization consists of pyrite and arsenopyrite and possibly a telluride mineral (calaverite?). Alteration includes potassic, argillic, silicification, sericite, chlorite, and fine sulphides. Multiple generations of quartz veining are locally restricted within the rhyolite host. The rhyolite unit has a strike length of 800 metres before being faulted off and may be up to 125 metres wide.

In 1988, grab samples yielded up to 6.63 grams per tonne gold and 132.7 grams per tonne silver, whereas chip samples yielded 2.46 grams per tonne gold and 29.7 grams per tonne silver (Assessment Report 18092).

Work History

The area has been explored in conjunction with the nearby Rhub (MINFILE 093F 054) occurrence and a complete exploration history can be found there.

In 1986, a stream and silt sediment sampling survey was completed by Newmont Exploration of Canada. During 1987 to 1988, Newmont conducted geological mapping, soil sampling, stream sediment sampling, rock chip sampling, hand trenching and geophysical surveys.
