The Big Red (Terry) occurrence is located at an elevation of approximately 750 metres on a steep south-southwest–facing slope, north of Terry Creek and west of the Barrington River.

The area is underlain by the Lower Jurassic Limpoke pluton of the Texas Creek Plutonic Suite, consisting of monzodioritic to gabbroic intrusive rock. The Limpoke pluton is a two-phase stock with a biotite hornblende quartz monzonite outer phase and medium-grained hornblende monozodiorite inner phase. Leucocratic potassium feldspar megacrystic syenite dikes and plugs intrude the eastern and western borders of the pluton and the surrounding Upper Triassic Stuhini Group sedimentary and volcanic rocks.

Locally, feldspar-porphyry dikes cut intermediate volcanic rocks and host disseminated chalcopyrite and pyrite associated with potassic alteration. The dikes range from a few centimetres to several metres in width with multiple orientations and have been mapped over an area of approximately 900 by 375 metres. Both sulphide abundance and potassic alteration intensity vary with the density of porphyritic dikes.

In 2019 and 2020, 75 rock grab samples were collected from the Terry zone with 32 samples yielding greater than 0.2 per cent copper, 6 yielding greater than 1 per cent copper, and others with values of up to 5.54 per cent copper, 42.1 grams per tonne silver and 0.54 gram per tonne gold (Equity Exploration Consultants Ltd. [2021-08-27]: Technical report on the Big Red Property, British Columbia, Canada).

In 2020, drillholes BR-20-023 and BR-20-025 yielded intercepts of 0.34 and 0.24 per cent copper, 2.41 and 1.43 grams per tonne silver with 0.06 and 0.04 gram per tonne gold over 120.4 and 172.2 metres, respectively (Equity Exploration Consultants Ltd.

Work History

The area has been explored on conjunction with the Ridge (MINFILE 104G 208) and a complete regional exploration history can be found there.

In 2019 and 2020, Libero Copper and Gold Corp. completed programs of geological mapping; geochemical (rock, soil and talus fines) sampling; a 549 line-kilometre airborne electromagnetic (ZTEM) survey; three diamond drill holes, totalling 610.0 metres and 24 reverse-circulation drill holes, totalling 3527.5 metres, on the area as the Big Red property.
