The Hal 4 occurrence is situated in the Kwanika Range south of Halobia Creek, approximately 50 kilometres east-southeast of Takla Landing.
The area is underlain by mesozonal plutonic rocks assigned to the Late Triassic to Early Cretaceous Hogem Intrusive Complex which have intruded volcanic and sedimentary rocks of the Middle Triassic-Lower Jurassic Takla Group east of the Pinchi fault zone. The plutonic rocks form an elongate batholith, extending from Chuchi Lake, north to the Mesilinka River.
The Hal 4 occurrence is situated in an area underlain by light coloured, medium to fine-grained granodiorite in contact with darker coloured, medium to coarse-grained monzodiorite to the west. Local granite/aplite dikes have been observed in monzodiorite west of this contact. These rocks have been propylitized, with chlorite and locally pervasive epidote common.
Two areas of limonitic, weathered granodiorite(?) talus hosting chalcocite in fractures with attendant malachite staining occur on the ridge south of Halobia Creek. The eastern gossan is 4 metres wide, with copper mineralization restricted to a 1-metre wide zone, while malachite staining at the western gossan occurs across a 5 to 6-metre width. Given its location on the ridge top, the talus is believed to have been derived locally. Later work, in 2011, identified malachite-stained fractures associated with sericite-altered diorite.
Samples taken in 1991 by Swannell Minerals (H91R05 and 7) from the eastern and western gossans assayed 1.60 per cent copper and 11.5 grams per tonne silver and 1.04 per cent copper and 20.8 grams per tonne silver respectively (Assessment Report 21734, Appendix II).
In 1992, chip samples (12078 and 12077) of fractured, limonitic quartz monzonite with strong malachite staining from the eastern and western gossans yielded 0.392 and 0.923 per cent copper, 16.0 and 23.0 grams per tonne silver with 0.225 and 0.120 gram per tonne gold over 1.0 and 4.0 metres, respectively (Assessment Report 22588).
Work History
In 1969, the Umex - Wenner Gren Joint Venture conducted reconnaissance stream sediment sampling in the area. Anomalous molybdenum values led to claim staking in 1971. In 1971, this group collected 369 soil samples and analyzed them for copper, molybdenum, and zinc. A discontinuous north-west trending copper/molybdenum soil anomaly was outlined measuring 300 by 1500 metres. The anomaly lies on the eastern part of the Hal 6 claim. In 1972, this group conducted geological mapping, line-cutting, 10.9 line-kilometres of induced polarization, 20 line-kilometres of magnetic surveys followed by 5 short diamond drill holes totalling 347 metres (Geology and Exploration in BC, page 447). Results for 1972 were not published.
In 1980, Dome Exploration Ltd. evaluated the claims for molybdenum and tungsten potential. A program of silt sampling, 10 test soil profiles and 52.5 line-kilometres of magnetic surveys were carried out.
In August of 1990, the Hal claims were staked on behalf of the Takla Joint Venture to cover the former Noble group and an area to the southwest of it. In 1990, Hal 1 to 6 claims was acquired by Major General Resources.
In 1991, operator Swannell Minerals Corp conducted prospecting, silt sampling (18), heavy mineral sampling (9) and rock sampling (5) on the Hal 1-6 group. No outcrop was located in the area of the previously defined soil anomaly. In 1992, follow up work by Swannell included reconnaissance survey grids, geological mapping over 20 per cent of the property, and rock (5 samples) and soil (110 samples) sampling. No porphyry style mineralization was located but exploration targets have been identified including; a) malachite infilled shear zones. Five samples collected in 1992 yielded copper results ranging from 1905 to 9230 parts per million with associated gold and silver values, b) A coincident copper/molybdenum soil anomaly on the Hal 6 claim and c) a contact zone between Takla volcanics and Hogem batholith rock in the southeast property area.
During 2005 through 2010, Redton Resources and Geoinformatics Exploration Canada Inc. undertook work on the regionally extensive Redton property, which covered the Falcon (MINFILE 093N 068) occurrence to the south (just north of Nation Lake) and north to the Tak (MINFILE 093N 067) occurrence, approximately 6 kilometres south of the Omineca River. In 2005, a 5764.0 line-kilometre airborne magnetic and electromagnetic survey was completed on the area as the Takla-Redton property. In 2006, a program of geological mapping and geochemical (rock, silt, and soil) sampling was completed on the property along with 12 diamond drill holes, totalling 4032.5 metres, on the Takla-Rainbow (MINFILE 093N 082) and Tak occurrences. In 2007 and 2008, programs of geochemical sampling (rock, silt, and soil) sampling, ground geophysical surveys and 10 diamond drill holes, totalling 3784.0 metres, were completed on the property. This work centred primarily on the Takla-Rainbow occurrence to the north and Falcon occurrence to the south. In 2010, a subsequent AeroTEM survey by Redton Resources identified 65 electromagnetic anomalies on the property.
During 2011 through 2014, Kiska Metals Corp. (previously Rimfire Minerals Corporation) completed programs of prospecting, geological mapping, geochemical (rock, silt, and soil) sampling and ground geophysical surveys on the Redton property. A combined 11.2 line-kilometre ground induced polarization and magnetic survey was completed on the Halobia Creek area.
