Capsule Geology

The Gingras Creek (Zone 3) showings are located at the headwaters of Gingras Creek, a southeast flowing tributary of Sulphurets Creek.

The area is underlain by green, red and purple volcanic breccia, conglomerate, sandstone and siltstone of the Lower Jurassic Unuk River Formation (Hazelton Group). A large stock of Lower Jurassic and younger diorite has intruded the Hazelton Group rock and its eastern contact is found within a kilometre to the west of the occurrence (Grove, Bulletin 63).

Two showings of asbestos, one with magnetite and some copper mineralization, occur within a kilometre of each other (Property File: Geology Map-Newmont Expl. of Canada Ltd.). Showings of magnetite are reported west and northeast of these asbestos showing. The nature of how the mineralization occurs and the host rock in which it occurs was not reported.

A mineralized area is located near the headwaters of Gringas Creek on the Unuk 24 claim (Assessment Report 17087). Within this zone, tuffs and andesites of the Unuk River Formation are silicified, seriticized, and contain 5-10 per cent finely disseminated pyrite. The area is coincident with a magnetic low and a VLF conductor.
