Harrison Cookenboo reports that the Duvay-Chenier Gold Project property in Quebec is located within the Superior Craton, which is an ancient Archean continental core of North America. The craton is comprised of Archean greenstone belts and intrusive granitoids, separated locally by shear zones and regionally significant faults. The granitoids are approximately 10 to 30 million years younger than the volcanic rocks of the greenstone belts, and thus intruded the volcanic-sedimentary strata relatively soon after deposition (Jackson and Cruden, 1995).
Deformation of the Abitibi Belt led to development of roughly almond-shaped domains with less severe deformation towards their centres, and more strongly deformed at their edges, where they are bounded by regionally significant faults and strongly deformed rocks (Borghetti et al., 2011). Borghetti et al. (2011) show that these almond-shaped domains occur at scales from the regional (100s of kilometers across) to outcrop (10s to 100s of meters across) to hand-sample (10s of centimeters across; rates a regionally significant compressional shear zone crosses the Duvay showings from east-southeast to west-northwest. The compressional shear zone is cut by later extensional quartz fractures, all of which are associated with gold mineralization. Based on detailed surface mapping and drilling, the shear zone cuts pillow basalts, basalt lavas, andesites, peridotites and gabbro variably altered by carbonate, quartz and gold bearing fluids.
The Duvay-Chenier Property is located within the Abitibi greenstone belt. Gold deposits within the Abitibi Belt are structurally controlled by faults or shear zones, and associated with variable amounts of disseminated sulfides. The mineralized zones are commonly silicified or carbonate-altered reflecting large quantities of hydrothermal fluids moving through the rocks. Quartz veins are common carriers of gold.
Exploration on the Property is focused on deposit types similar to other gold occurrences in the Abitibi Greenstone Belt: shear zones and faults, associated with variably disseminated sulfides, and quartz veins. Intersections of the shear zones and quartz veins are considered especially promising targets.
