The Jackie showing is located to the south of the Willison Glacier near the headwaters of Willison Creek. The Falcon showing (104M 087) is 825 metres to the north.
The claims cover biotite-quartz-schists, quartz-sericite schists, gneisses, and limestones of the Middle Devonian. The metasediments are cut by numerous northwest-trending alaskite dikes.
Massive sulphide pods occur in limestone and biotite-muscovite-sericite schists, generally near the contacts between the units. Large zones of limonite alteration, cut by alaskite and hornblende porphyry dikes, usually surround the pods. The lenses appear to be widest near the dikes. Several faults follow the general direction of the dikes, suggesting structural control on the mineralization. Sulphides comprise galena, sphalerite, chalcopyrite, pyrrhotite, and pyrite. The pods are up to 30 metres long and 6 metres wide. The smaller pods host sphalerite and galena mineralization and the larger pods vary mineralogically along length. Galena, quartz, and calcite dominate the northwest, changing to pyrrhotite, chalcopyrite and pyrite in the centre and border areas. The widest significant intersection averaged 0.025 grams per tonne gold, 21.8 grams per tonne silver, 0.08 per cent copper, 0.98 per cent lead, and 6.39 per cent zinc over 7 metres (Assessment Report 21162).
WORK HISTORY
Falconbridge Ltd. included the Willison Bay area in a regional prospecting program conducted in 1966. The Jackie and Falcon prospects were discovered during this program and limited trenching and sampling were completed. The property was staked in 1989 by geologist Kim Hudson, who then collected 32 samples for analysis, including two for lead isotope analyses from the Jackie showing (Assessment Report 20098). Carmac Resources optioned the property from Hudson, and in 1990, spent 31 days, representing 72 man-days of labour between July 26 and August 25, evaluating the property (Assessment Report 21162). During this time, they completed 145 metres of trenching in 35 trenches. A total of 344 rock chip - and three silt samples were collected and sent for analysis. Carmac conducted detailed geological mapping, channel sampling, and geophysical surveying consisting of 5 kilometres of VLF-EM and magnetometer work.
In 2018, exploration work was completed on behalf of Zimtu Capital Corp. by a two-man geologic crew in the second week of September (Assessment Report 38238). The first day consisted of airborne reconnaissance, followed by one day ground reconnaissance. Eight rock samples from bedrock were collected near and around the Falcon and Jackie Showings.
