The New Limpoke showing is underlain by the early Jurassic Limpoke pluton of the Texas Creek plutonic suite (189-195 Ma) consisting of monzodioritic to gabroic 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. Chalcopyrite occurs chiefly in northwest dipping, altered granodiorite rather than the volcanics. Disseminated chalcopyrite is sparse and the reported grade is low. Other sulphides include pyrite, pyrrhotite and molybdenite.
The Pokey SE zone occurs at the head of Pokey Creek at UTM 6406940 North and 330040 East, about 375 metres north-northeast of the plotted MINFILE location of New Limpoke. The zone is characterized as a 50 metre(?) wide, high level, hydrothermal breccia pipe consisting of broken, kaolinized and calcified monzonite, cemented by banded ankerite and chalcedony. A weak anomaly accompanies traces of pyrite in the breccia matrix One sample taken in 1990 gave 0.14 gram per tonne gold upon re-assay by coarse-gold methods (Sample 102207, Assessment Report 20988). Another sample located about 300 metres northwest of the MINFILE plot and 300 metres southwest of the Pokey SE zone assayed 0.05 gram per tonne gold, 1 gram per tonne silver and 0.27 per cent copper (Sample 447002, Assessment Report 19439).
The area was originally explored by Teck Explorations and Dupont in the early 1980’s, with work centering on the Tuff (MINFILE 104G 121) and New Limpoke occurrences. Between 1988 and 1992, Integrated Resources explored the area under the Goat and IR claims and completed programs of geochemical sampling, geophysical surveys, geological mapping and a diamond drill hole, totalling 110 metres (Bob (104G 216). 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 the following mineral occurrences: 104G 001 (Poke Showing), 104G 002 (Gordon Showing), 104G 024 (New Limpoke), 104G 121 (TUFF), 104G 206 (TGR (North), 104G 207 (TGR Vein), 104G 208 (Barrington Vein), 104G 209 (Upper Cave Creek), 104G 210 (West Grid), 104G 211 (Northe Barrington), 104G 212 (Target 4), 104G 213 (Boundary Vein), 104G 214, (Terry Creek), 104G 215 (Jimmie), 104G 216 (Bob), 104G 217 (Zamba), 104G 218 (Spike, Waterfall), 104G 230 (GRAN 16). Divitiae collected 12 rock samples in the southern portion of the property. Selective samples ran above 1 per cent copper.
In 2017, Divitiae Resources contracted Precision GeoSurveys Inc. to undertake an airborne magnetic and radiometric geophysical survey in late September that covered all of the River of Gold claims totalling 536 line-kilometres. Divitiae's River of Gold property was the renamed Big Red claim group of 2014 with more claims attached extending 5 kilometres west covering Poker occurence (104G 149). 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).
Results of the ASTER survey are as follows. Four high probability clusters of phyllic alteration occur across the River of Gold claim block. Two clusters are coincident with high probability propylitic alteration and one is coincident with both propylitic and silica alteration. Several clusters of high probability iron oxide alteration occur throughout the River of Gold claims and indicate potential for gossan development. Advanced argillic and argillic alteration data suggests elevated clay formation surrounding a central zone of coincident phyllic-propylitic alteration in the centre of the River of Gold claim block. Similar elevated clay abundance occurs about 4 kilometres to the southeast of the central phyllic target on the property. Layer-stacking of phyllic, argillic and propylitic alteration maps have helped identify areas in which coincident hydrothermal alteration may be present. This resulted in two such target areas being found. A 600 metre diameter broadly circular zone of weak propylitic and phyllic alteration enclosed by weak argillic alteration is located within the NE portion of the River of Gold claims. Company interpretation of the zonation that was evident suggested a high-level porphyry system. A second anomalous zone occurs in the central portion of the River of Gold claims where coincident phyllic-propylitic alteration is enclosed by argillic alteration.
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.
