The property lies below treeline and is covered by a veneer of colluvium and glacially-derived sediment. The large geochemical footprint, along with widespread mineralization and alteration, suggest the possibility that the Teako stock and surrounding country rocks may host a significant molybdenum-silver-copper-gold porphyry style hydrothermal system.
The Teako property is at an early stage of exploration and is particularly exciting given that it represents a prospect that has never been explored systematically and which has never been drill-tested; it certainly warrants additional exploration work.
Work recommended for the next stages of exploration will consist of an induced polarization survey, with additional detailed soil sampling and hand trenching to help delineate potential porphyry-related and high-grade vein targets. This will be followed up with approximately 3000 m of diamond drilling designed to test the most prospective geochemical and geophysical targets on the property.
HIGH GRADE AU-AG VEIN AND BULK TONNAGE MO-AG-CU-AU PORPHYRY PROSPECT
- Located near infrastructure in a belt of major porphyry and gold-rich vein deposits.
- The property totals 1,019 hectares, and lies approximately 15 km by road from Kitwanga and a further 150 and 240 km to deep-sea ports with ship loading facilities at Kitimat and Prince Rupert, BC, respectively.
- The property is situated 1.5 km northwest of the cross-Canada rail network that terminates at Prince Rupert, and would be ideal for transporting concentrate.
- Grid power is available approximately 6 km southeast of the property.
- Rock samples collected between 2012 and 2018 returned up to 21 g/t gold, 81.3 g/t silver, greater than 1% copper, and 1687 ppm molybdenum.
- The property hosts an approximately 600 m wide by 800 m long copper-gold-molybdenum-silver geochemical anomaly.
The Teako property covers an extensive area with showings of copper-gold-molybdenum-silver mineralization and high-grade precious metals veins that together are strongly suggestive of bulk-tonnage and high-grade potential.
Teako Gold Corp. has an option to earn a 100% interest in the 10 km2 property, which is located in west-central B.C., approximately 15 km west-southwest of the village of Kitwanga.
The property is road accessible, the Provincial power grid is less than 6 km away, and the cross-country rail network is located just 1.5 km southeast of the property.
Deep seaports with loading facilities are located close by at Prince Rupert, Kitimat, and Stewart BC.
The Teako property lies within the Stikine terrane, which hosts prolific porphyry and high-grade vein deposits and mines, especially within the Golden Triangle region. About 100 km northwest of the Teako Project, The Golden Triangle hosts some of the world’s largest and richest mineral deposits. These include gold rich deposits such as Eskay Creek, Brucejack, Premier, Snip, and copper-gold rich deposits such as KSM, Galore Creek, Red Chris and Granduc. Deposits are typically Early Jurassic in age. Younger Cretaceous to Eocene porphyry and high-grade vein deposits and mines continue further south through the regional area of the Project and include the past-producing Silver Standard, Rocher Deboule, Kitsault, Huckleberry, Bell, Granisle, Morrison and Endako mines.
The Teako property straddles the boundary between the late Middle to latest Jurassic or earliest Cretaceous Bowser Lake Group to the northwest and the Early Cretaceous Skeena Group to the southeast.
Both units consist largely of sedimentary rocks and are apparently separated by a regional-scale northeast-southwest trending fault that transects the central part of the property. The Bowser Lake Group sedimentary rocks northwest of the fault have been intruded by the informally named Teako stock, which is exposed in the core of the property and around which the majority of the mineralization is centered.
Prospecting at Teako has identified several areas of mineralization, mostly exposed along logging road cuts which expose sedimentary and lesser intrusive rocks that are both mineralized. Mineralization is predominantly structurally controlled and consists of quartz-carbonate veins containing a typical sulphide assemblage of pyrite-arsenopyrite- chalcopyrite-molybdenite±tetrahedrite with secondary malachite and scorodite staining. Peak values of 21 g/t gold, 81.3 g/t silver, greater than 1% copper and 1687 ppm molybdenum were obtained from grab samples collected within the known areas of mineralization.
Limited rock samples were collected from the largely covered Teako Stock, but a sample of iron carbonate and hematite stained quartz monzonite cut by a 2 cm wide quartz-molybdenite-pyrite vein graded 882 ppm molybdenum, 1.7 g/t silver and 0.015 g/t gold, while a sample of silicified subcrop with minor pyrite yielded 0.92 g/t gold, 3.2 g/t silver, 445 ppm lead and 10 ppm molybdenum.
Distal to the Teako Stock, small lenses of gold-bearing semi-massive pyrite are common in exposures along road cuts.
In the 2018 exploration program, a large soil grid was established over the claim block to help determine the size and strength of the mineralizing system on the property. The soil geochem work outlined a very encouraging 600 m wide by 800 m long copper-gold-molybdenum-silver geochemical anomaly that mainly overlies the Teako Stock and the immediately adjacent Bowser Lake Group rocks.
The Teako stock is characterized by a low magnetic response, likely due to strong hydrothermal alteration and associated magnetite destruction.
The magnetic low signature of the Teako stock is typical of porphyry type intrusions in the area, giving it potential to host a significant porphyry style hydrothermal system.
