Pahtavaara – Geology & Exploration
Mineralistion is hosted by amphibolitized komatiites. The principal geologic control in the area is a linear structural corridor that trends east-west, forms multiple folds, and dips steeply to the north on the south side and steeply south on the north side. The mineralized zone identified on Rupert’s Pahtavaara property is characterized by hydrothermal alteration and mineralization within various phases of pervasively altered komatiites. Mineralization remains open at depth along the entire zone. The hydrothermal alteration and the Au-bearing veins associated with it are deformed. Because they were competent rocks (massive amphibole), they resisted deformation. They are therefore less deformed than the adjacent talc-chlorite schists. This implies early brittle deformation followed by ductile deformation.
Rupert’s program to date has focussed on FIVE areas of near mine mineralisation (1) Karoliina, (2) Vilhelmiina, (3) North Flank West, (4) North Flank East and (5) Samuri
