Capsule Geology

The Amethyst area is underlain by Upper Triassic Stuhini Group volcanic, volcaniclastic and sedimentary rocks intruded by a Late Triassic diorite phase of the Stikine (or McQuillan) Plutonic Suite.

Prospecting in 1990 by South Unuk Gold Corp on the southwest corner of the Mikey 1 claim identified three zones of interest: the 7169, Amethyst and 7230. The area consists of andesitic tuffs, sandstone and siltstone.

The 7169 area, measuring approximately 100 by 200 metres in size, hosts several subparallel quartz veins varying in width from 2 to 100 centimetres. Individual veins pinch and swell along strike. Mineralization consists of disseminated pyrite with minor chalcopyrite. Sample 7169 assayed 2.45 grams per tonne gold, 0.09 per cent copper and 1 gram per tonne silver (Assessment Report 21332).

At the Amethyst showing, about 200 metres southeast of the 7169 showing and continuing into the northwest corner of the Jumbo 1 claim, numerous sub-rounded to sub-angular boulders varying up to 1.5 metres across were found to host fracture controlled and brecciated galena and purple amethyst mineralization. Individual fracture stringers of mineralization vary up to 4 to 5 millimeters across. The host rock are reddish in colour and cherty or jasperoidal in composition. Sample 29016 assayed 0.018 per cent copper, 3.16 per cent lead and 7.69 per cent zinc; sample 29023 assayed 295.20 grams per tonne silver, 11.80 per cent lead, and 0.03 per cent zinc (Assessment Report 21332). Samples yielded only low gold values.

At the 7230 showing, in the northeast corner of the Jade 1 claim narrow, discontinuous mineralization was located within an ankerite altered northeast-southwest trending shear zone. Mineralization consisting of malachite, chalcopyrite, tetrahedrite and galena occurs in sheared veins 0.2 metre wide and 2 to 3 metres in length, hosted within andesite flows. Sample 7230 assayed 1721.16 grams per tonne silver, 1.14 per cent lead and 2.04 per cent zinc (Assessment Report 21332).
