Project Areas
The project areas are located about 30 kilometres east of Thompson and are held in two blocks referred to as Bryce Bay, located north of Bryce Bay and Thompson-East claims which are directly east of Thompson. Access to the prospect area is by four-wheel drive truck, all-terrain vehicle, boat and motor or snowmobile.
Geology and Exploration
Supracrustal (Proterozoic) Ospwagon Group rocks, including psammites, pelites, calcareous sediments and iron formation are intersected in the project area of the Thompson Nickel Belt (TNB). The Ospwagon rocks are intruded by mafic and ultramafic dykes and host the massive to disseminated nickel-rich sulphide bodies of the Thompson mines. Boreholes drilled on the Thompson East Claims by Anglo American have intersected what is believed to be the Pipe Formation – the host formation for most of the nickel-rich deposits.
Anglo American conducted exploration in the early 2000s in the Grass River and Thompson –East area. This included an airborne “spectrum” (magnetic, electromagnetic, radiometric and terrain) survey which delineated 27 EM conductor zones that warranted follow-up ground work. Follow-up exploration included ground geophysical surveys and diamond drilling boreholes within the conductor zones.
Till Geochemistry
Eight of these 27 conductor zones lie within the Thompson-East claims and because outcrop is limited, and to advance exploration, till geochemistry investigations have been undertaken within or directly down-ice direction on seven of the zones by the property owner.
To date, over 200 boreholes have been augered, samples recovered, and till assay values recorded for the project area. The till assay data have been most useful in identifying preferred locations for additional borehole drilling.
thoMPson-eAst: High Ni values, 131.5 and 90.8 ppm have been determined by assays for till samples collected from two of the boreholes augered on claim (MB 11598) which overlies the strong EM anomaly of conductor zone 23. These Ni concentrations are similar to some of the values from till deposits directly overlying or within 750 m of Pipe Lake, Thompson
C Pit, and Soab Lake mine (McClenaghan et al.). In addition, high Ag assay values of 771, 363 and 246 ppb were recorded for till samples recovered from boreholes sampled on this claim.
To the north, but on strike with conductors on this claim, anomalously high concentrations of Ag (210 ppb) and Zn (95 ppm) are present in the till overlying conductor zones 10 and 12.
bryCe bAy: Till of the Bryce Bay claims (MB 9514, MB10467, MB12045) north of EM conductor zones located from the Spectrum survey have anomalous high As, Au, Ag, Pt, Pd, and Cr concentrations. Initial channel sampling of a massive sulphide vertical dipping vein up-ice of the anomalous till concentrations provided Ag concentrations as high as 3.13 ppm, maximum Cu values of 8,500 ppm and Co values up to 1,610 ppm.
2020 Highlights and Update
During September and October 2020, additional work was completed on
claims of the Bryce Bay and Thompson East Project. This included locating and marking target areas for till geochemistry augering and sampling on MB Claim 11598 (Thompson East), where initial sampling recovered till Ni values of up to 131.5 ppm. Two additional zones are to be sampled by augering 20 to 30 boreholes on each target area during the 2021 winter period.
Snowmobile access trails for transport and sampling by a portable drill were also completed during this period. Additional access trail line cutting and deadfall clearing was also completed to provide access for a planned summer drilling program of up to five shallowcored boreholes (BQ) on the Bryce Bay Project area. Previous channel sampling of a sulphide vein on MB claim 12045 provided Ag concentrations as high as 3.13 ppm, Cu values of 8,500 ppm, and Co concentrations 1,610 ppm. A previously drilled eight-metre borehole also showed anomalous high titanium XRF values of up to 3.5 per cent.
