The region of the Tbor occurrence is underlain by two phases of the Hogem Batholith that intrude sedimentary rocks of the Upper Triassic Inzana Lake Formation (Takla Group). One phase consists of Late Triassic to Early Jurassic gabbroic to dioritic rocks; the second consists of Early Jurassic quartz monzonitic to monzogranitic intrusive rocks. The Tbor rock pit at 15.5 kilometres on the T-road exposes altered, moderately magnetic syenite with local potassium feldspar phenocrysts and veinlets and 1 to 3 three per cent pyrite-hematite and magnetite. Minor chalcocite/chalcopyrite occurs along fractures and as minor disseminations. Work History The Hi claim group encompassed the later Tbor showing area and was staked in 1969 for the N.B.C. Syndicate. Geological mapping, soil geochemistry, ground electromagnetic and magnetometer surveys were carried out in 1969 and 1970. In late 1970, Tchentlo Lake Mines acquired the Hi group from N.B.C. Warren (Assessment Report 26451) reports that, in 1971, the N.B.C. Syndicate located a large copper geochemical anomaly that had not been followed up. The anomaly measured 1.5 kilometres in length and up to 300 metres in width centred over a regional magnetic feature. In 1981, Placer Development Limited explored the JP 1 claim, which covered some of the same ground as the previous Hi group and the later Falcon 3 and Tbor claims but did not include the Tbor showing. They conducted geochemical and geophysical surveys. A 1-kilometre long copper anomaly was outlined by widely spaced sample stations (Assessment Report 9403). In 1989, Arthur Halleran held the Falcon 1 to 4 claims, with the Falcon 3 and 4 covering the HI and JP 1 areas (Assessment Report 20272). Independence Mining Company Inc optioned the Falcon claims and conducted a geological and geochemical program in 1990, collecting 690 soil samples (Assessment Report 20825). The Bor and Tbor claims were staked by Chris and Lorne Warren and were prospected in the fall of 1999 to cover new showings exposed by road building in the Contact zone area, including the Bor gravel pit, which consists of open fractures filled with pyrite, magnetite and chalcopyrite (Assessment Report 26451). The Tbor claims cover some of the same ground that the HI claims covered and some of the same area (its southeast claims) as Placer’s 1981 JP 1 claim. The BOR and TBOR claims lapsed in 2003 and were added to the Redton property in 2005. Subsequent work on the Contact zone by Geoinformatics Exploration Canada Inc included geochemical sampling and airborne electromagnetics and magnetics (Assessment Report 32504). In 2007, Geoinformatics Exploration Canada Inc undertook work on its regionally extensive claim group which covered the Tbor area.
