Jun 25, 2018 (Therese Pettigrew) - Molybdenite has been found in four pegmatite quartz veins distributed over a distance of 1.6 km along the contact of the tongue of granititc rock which, in lots A and B, concessions 2 and 3, Conmee township, extends north from the batholith. The largest of these veins is on the north side of the road in the southern part of Lot B, Concession 3. The vein consists of fine-grained, translucent, white quartz in which occurs amorphous molybdenite, in thin streaks and platy segregations, lying parallel to the walls and irregularly spaced through the vein. Small amounts of disseminated pyrite and chalcopyrite are present. The major part of this siliceous deposit is a vein 6.1 m wide, with few inclusions, and strikes approximately 50 degrees east and dips 80 degrees southeast. The 122 kg (270 lb) sample collected in 1918 assayed 1.29% MoS2 (Tanton, 1931).
