Agnico-Eagle Mines¿ Meadowbank mine is located in the Kivallik region of Nunavut. Research to date has mostly been concentrated on the geological mapping of the Portage ore body with an emphasis on the chemical signature of host rocks, the geometry of the deposit and its structural controls, and on the ore and associated mineral assemblages. The lithological sequence of the deposit consists of Neoarchean metamorphosed volcaniclastic rocks, banded iron formation (BIF), ultramafic rocks and quartzite. The predominant gold mineralization is hosted in BIF and is associated with pyrrhotite and pyrite, which have replaced magnetite. Gold also is found in high-grade quartz veins in volcaniclastic rocks. Four deformation events affect the host rocks, including two generations of faults and several folding phases"--Provided by publisher. |
