Summary(Plain Language Summary, not published)
The study of the Meadowbank deposit is part of NRCan¿s Targeted Geoscience Iinitiative-4 Program that aims at improving our understanding of Canada¿s major mineral systems. Agnico-Eagle Mines¿ Meadowbank mine is located in the Kavallik region of Nunavut. Research to date has mostly been concentrated on the geological mapping of the Portage and Goose orebodies. The lithologic sequence of the deposit consists of volcaniclastic rocks, banded iron formation (BIF), ultramafic rocks and quartzite. The predominant gold mineralization is associated with pyrrhotite and pyrite, which have replaced magnetite. The ore zones are approximately 7 m wide (5 up to 40 g/t) and hosted in the BIF. Gold also is found in high-grade quartz veins in volcaniclastic rocks. Four phases of regional deformation affect the host rocks, which have been strongly metamorphosed. Targeted geochronology, structural, petrographic and geochemical analyses are underway to characterize the deposit and ultimately establish the hydrothermal footprint, timing of gold introduction and structural controls.
