Mineralization Comments

Oct 05, 2022 (Therese Pettigrew) - The F-Zone Ni-Cu sulphide mineralization is associated with a series of komatiitic flows that subcrop beneath Charlewood Lake and have a strike length of approximately 600 m and a thickness of between 50 to 200 metres. Sulphide mineralization appears to be restricted to a footwall embayment into the dacitic volcanics identified by the ground magnetic survey. Reconnaissance diamond drilling in this area discovered that the footwall embayment structure hosts a mineralized nickel-bearing channel. The overall F-Zone is at least 200 m long and locally up to 18 m wide. Limited drilling (18 holes) encountered disseminated to net-textured to massive nickel-bearing sulphides at the komatiitic/dacite contact. Significant drilling results from the F-Zone ranged from 0.81% to 4.54% Ni over widths ranging from 0.25 to 17.6 metres. The F-Zone is open at depth. The main sulphide zone of the F-Zone is composed of heavily disseminated to net-textured sulphides that comprise between 5% and 25% of the rock. Brereton (2003) interpreted the sulphide mineralization as plunging vertically or steeply to the southeast. The sulphide zone also appears to undulate down plunge. There are several untested, strong, off-hole conductors identified by downhole pulse-EM surveys in the area of the F-Zone (ibid.). The F-Zone (Thalweg) contains primarily pyrrhotite and pentlandite with trace amounts of chalcopyrite and also a grey alteration mineral (nickel phase? titanomagnetite?). The nickel tenors in the F-Zone range from 4% to 43.3% Ni in 100% sulphide, but average approximately 5 to 6% Ni in 100% sulphides. The F-Zone is interpreted as a Type I Kambalda-style komatiite-hosted sulphide deposit (Jobin-Bevans and Davis, 2021).
