The Terry Creek occurrence area is underlain by the early 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 surrounding Upper Triassic Stuhini Group sedimentary and volcanic rocks.
At the Terry Creek, a northwest-trending pyritic syenomonzonite dike intrudes into a granodiorite and contains massive sulphide pods with mineralization being traced intermittently for 250 metres. In 1990, chip sampling of the massive sulphide pods returned values of 0.73 gram per tonne gold gold with 11.00 per cent copper across 0.6 metre and 0.52 gram per tonne gold with 0.4 per cent copper over 1.0 metre (Assessment Report 20988).
In 2017, sample 2692848 was collected about 500 metres east of the Terry Creek showing and 700 metres northwest of the Gordon showing (104G 002). The sample was taken in a creek where faulted siltstone outcrop hosts pyrite, chalcopyrite and malachite mineralization along with potassic alteration in veinlets and pervasive chlorite. The sample assayed 0.9 per cent copper, 0.41 gram per tonne gold and 4.95 grams per tonne silver (Assessment Report 36930). Values for zinc and lead were not anomalous.
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 and1992, 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, totalling 110 metres. In 2002, Newcastle Resources and Viceroy Resources staked the area as part of the Target 1-4 claims and completed a prospecting program.
In 2014, Divitiae Resources spent 2 weeks on its Big Red property which covered 18 MINFILE occurrences. Divitiae collected 12 rock samples in the southern portion of the property. Selective samples ran above 1 per cent copper (Assessment Report 35466). No sampling occurred in the Terry Creek area.
By 2017, Divitiae had expanded their Big Red claim group extending it 5 kilometres more to the west, covering the Poker (104G 149) occurrence. Divitiae changed the property name from Big Red to River of Gold and undertook an airborne magnetic and radiometric survey in late September that covered all of the River of Gold claims totalling 536 line-kilometres. In October of 2017, preliminary prospecting was completed on high probability anomalies generated by previous ASTER analysis, and the new airborne geophysics. At this time 64 rock samples were collected. Work on the northern portion of the property failed to find any samples to be assayed. The complete airborne geophysical survey report is attached as an appendix within Assessment Report 36930.
See New Limpoke (104G 024) for more detailed information and for 2017 ASTER survey 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.
