Résumé(disponible en anglais seulement)
The orogenic Island Gold deposit, located in the Michipicoten greenstone belt, is part of the Goudreau-Lochalsh gold district. Preliminary results indicate that gold is hosted in multiple subparallel mineralized zones along well-defined shear zones that generally strike east-northeast with a steep southerly dip. The alteration envelope is a combination of silicification, sericitization, carbonatization, pyritization and chloritization. Quartz "flooding" (silicification) as well as quartz veins are often present at the core of these alteration envelopes and commonly contain visible gold. Alteration quickly decreases in intensity away from the veins and deformation corridors. Ongoing work aims at further characterizing the alteration styles and compare with other orogenic gold deposits and at constraining the source of the gold-bearing fluid and conditions of gold mineralization. Achieving these objectives will aid in exploration efforts to expand resources and find new deposits as well as contribute to the understanding of orogenic gold deposits.
