Capsule Geology

The Conuma showing is in the headwater region of Conuma River, approximately 2 kilometres east of Tarn Peak and Shangri-La Lake. It is situated approximately 31 kilometres northwest of the town of Gold River and 16 kilometres east of the village of Tahsis.

Basaltic volcanic rocks host polymetallic quartz veinlets with anomalous assays for gold, silver, copper, lead, zinc and molybdenite on the Conuma property. These veinlets may be part of a quartz stockwork zone that underlies a volcanogenic massive sulphide lens. The Conuma property itself is underlain by Paleozoic sedimentary rocks of the Buttle Lake Group and widespread Mesozoic volcanic rocks of the Middle to Upper Triassic Karmutsen Formation. These rocks are intruded by granitic rocks of the Early to Middle Jurassic Island Plutonic Suite and probable metamorphic rocks of the Paleozoic to Jurassic Westcoast Crystalline Complex.

Fracture controlled sulphide mineralization consists mainly of pyrite, pyrrhotite, chalcopyrite and malachite. Less common are fractures containing trace magnetite. Not all fractures are mineralized. Fractures generally trend northeast-southwest and northwest-southeast. Fault controlled sulphide mineralization consists mainly of pyrite, pyrrhotite, chalcopyrite, malachite. Oxidized iron-bearing sulphides are more intense in fault-controlled zones.

Work History

In a 1999/2000 Prospecting Report on the Elisir claims (Efrem Specogna), mineralization was recognized by prospectors in the Conuma Valley. Rock sampling identified molybdenite, chalcopyrite and pyrrhotite within quartz veinlets/veins hosted in volcanic rocks. Lamprophyre dykes and amphibolites were recognized in outcrop. Best assay results from probable float samples were rock sample B48636 (Breccia boulder in road rubble) with 0.02 per cent Zn, 0.4 per cent Cu, 4.4 grams per tonne Ag and 0.09 grams per tonne Au; and rock sample B48327 (Mo in quartz vein in volcanic) with 0.4 per cent Mo (Assessment report 26394).

In 2011, 2013, 2014 and 2015 Red Hat Metals Inc. conducted programs of rock, stream sediment and moss-mat sampling and prospecting over their Conuma property. An airborne magnetometer survey was also conducted in 2011. The exploration efforts outlined several new mineral occurrences in the Conuma River area, with assays up to 1.69 grams per tonne gold, 13.0 grams per tonne silver, 0.72 per cent copper, 0.04 per cent lead and 0.21 per cent zinc from a float sample (986262: Quartz veinlet).
