The Lower Jackie occurrence is located on an east facing ridge, approximately 1.7 kilometres northwest of the northern end of Twaddle Lake, at an elevation of 670 metres.
The area is underlain by Upper Triassic Karmutsen Formation (Vancouver Group) volcanics comprised mainly of pillowed basalts, tuffs and breccia. The Karmutsen rocks are intruded by Jurassic granodiorite of the Island Plutonic Suite.
The property is underlain by a sediment-sill unit, in fault contact with Karmutsen mafic flows. The former consists of thin- bedded argillites and siltstones interbedded with cherts, cherty and mafic tuffs, minor calcareous sediments, chloritic schist and graphitic lenses and zones. Interbedded sills are of andesitic and basaltic to gabbroic compositions. Diorite intrudes the sediment-sill unit in the eastern part of the claim group along a northwest trending contact.
Locally, a sheared limestone band, 6 metres wide, near its contact with quartz diorite and coarse-grained diorite, hosts galena, sphalerite, chalcopyrite and pyrite mineralization as banded and disseminated lenses with quartz veins and veinlets.
In 1985, samples yielded up to 9.6 grams per tonne gold from a pit adjacent to the showing (Assessment Report 14319).
In 1987, ICP analyses reported values to 21.9 parts per million silver, 685 parts per billion gold, 361 parts per million copper, 6399 parts per million lead, 9535 parts per million zinc and 137 parts per million cadmium (Assessment Report 16557, page 28).
In 1989, drillhole 89-1 intercepted numerous sections of disseminated pyrite and pyrrhotite with traces of sphalerite and chalcopyrite but with low values. The best section assayed 0.209 per cent zinc (sample 61340; Assessment Report 19084).
Other limonitic zones and minor sulphides are reported on the Jackie 2 and Bonbonaz 4 claims. Minute gem quality garnets, light orange-red in color, are reported from the Jackie 2 claim.
During 1984 through 1987, Canamin Resources completed programs of prospecting, geological mapping, trenching and rock, silt and soil sampling on the area as the Jackie and Bonbonaz claims. In 1989, Doramin Resources completed a program of sampling and a lone diamond drill hole, totalling 102.6 metres.
