The region of the Contact showing 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 and the second phase consists of Early Jurassic quartz monzonitic to monzogranitic intrusive rocks.
The Contact zone prospect features pyrite plus or minus chalcopyrite, malachite-bearing fractures and joints occurring within monzodiorite host rocks. Placer Development collected a rock sample in this area in 1981 that yielded 0.5 per cent copper (Assessment Report 9403).
WORK HISTORY
The Hi claim group was staked in the JP 1 area in 1969 for the N.B.C. Syndicate. Geological mapping, soil geochemistry, ground electromagnetic and magnetometer surveys were carried out in 1969 and 1970. Warren (Assessment Report 26451) reports that in 1971 the N.B.C. Syndicate located a large copper geochemical anomaly which had not been followed up. The anomaly measured 1.5 kilometres in length and up to 300 metres in width centered over a regional magnetic feature. In late 1970, Tchentlo Lake Mines acquired the Hi Group from N.B.C.
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 claim. They conducted geochemical and geophysical surveys. A 1 kilometre long copper anomaly was outlined by widely spaced sample stations (Assessment Report 9403). Placer Development collected a rock sample that yielded 0.5 per cent copper Assessment Report 9403). Placer mapped syenodiorite and gabbro in the JP 1 (Contact zone) area.
The Bor and Tbor claims were staked by Chris and Lorne Warren and were prospected in the fall of 1999 (Assessment Report 26451). The Tbor area covers some of the same ground that the Hi claims covered and some of the same area as Placer’s 1981 JP 1 claim. In 1989, Arthur Halleran prospected the Falcon 1-3 claims (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).
In 2007, Geoinformatics Exploration Canada Inc. and Redton Resource undertook work on its regionally extensive claim group which covered the JP 1 (Contact zone) and Tbor area.
In 2010, a subsequent AeroTEM survey by Redton Resources identified 65 EM anomalies (Assessment Report 31933). The survey covered the Contact zone area.
The 2011 Redton-South field program Redton Resources Inc. included geological mapping, prospecting (99 rock samples), soil/silt sampling (1125 soils, 37 silts) and 63.7 line-kilometres of ground-based IP/resistivity and magnetics (Assessment Report 34050). Work in delineated a new target are, the Contact Zone, which comprises a coincident IP-high/Res-low that is hosted within Hogem monzodiorite. The Contact zone work grid centres on the JP 1 showing. Highlighted grab samples in the Contact Zone contain up to 0.8 per cent copper. Soil samples collected in the Contact Zone show a strong correlation between copper-gold-silver.
In 2012, Kiska Metals (previously Rimfire Minerals Corporation) conducted a field program, consisting of the collection of soil samples and prospecting (Assessment Report 34050). A total of 568 soil samples were collected in 2012. Grid E was located north of the Falcon prospect, consisting of 4 lines spaced at 250 metres in and east-west direction. A total of 83 soil samples were collected from this grid, the eastern limit of which was at or near the location of the Contact zone (JP 1 showing).
See Falcon (093N 068) for related geological details and information on the Redton property which the Contact zone was also part of in the 2000s and 2010s.
