The TGR North showing area is underlain by sedimentary and minor volcanic rocks of the Upper Triassic Stuhini Group which are intruded by the Limpoke pluton (Texas Creek Plutonic Suite), 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 intrude the eastern and western borders of the pluton and surrounding Stuhini rocks.

A grab of a quartz-carbonate vein with arsenopyrite selvages and 1.5 centimetre wide veinlets with sulphides (arsenopyrite(?) and traces of chalcopyrte) hosted by monzodiorite. In 1991, two grab samples were collected, returning up to 8.7 grams per tonne gold (Assessment Report 21998).

Work History

The area was originally explored by Teck Explorations and Dupont in the early 1980’s, with work centering on the Tuff and New Limpoke occurrences (MINFILE 104G 121 and 104G 024). Between 1988 and 1992, Integrated Resources explored the area as the Goat and IR claims and completed programs of geochemical sampling, geophysical surveys, geological mapping and a diamond drill hole on the Bob showing (104G 216) totalling 110 metres. In 2002, Newcastle Resources and Viceroy Resources staked the area as a part of the Target 1-4 claims and completed a prospecting program.

See Ridge (104G 024) and West (104G 210) for detailed work history information and for 2017 property-wide ASTER results.

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.
