Capsule Geology

The Falcon showing is located immediately south of the Willison Glacier. The Jackie showing (104M 031) is 825 metres to the south.

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.

The Falcon showing consists of two northwest trending quartz veins with mineralization comprised of galena, sphalerite, pyrite, chalcopyrite, arsenopyrite and stibnite. The vein system is exposed for 25 metres and the strike extensions are covered by talus. Individual veins are up to 1.2 metres wide. To the northwest, a quartz-feldspar porphyry breccia contains smaller quartz veins with semi-massive arsenopyrite and stibnite.

A 2.2-metre-wide sample of the vein system assayed 3.3 grams per tonne gold, 2641 grams per tonne silver, 0.15 per cent copper, 2.5 per cent lead and 3.32 per cent zinc, 5.78 per cent arsenic and 2.56 per cent antimony (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.
