In 1975, a heavy mineral sampling survey was conducted in 2 areas: Beauce and Gaspésie. In Beauce area, sampling covers 1200 km2. A total of 83 samples were collected at an average density of 1 sample per 15 km2.
In Gaspésie area, a group of samples was collected around McGerrigle batholite. A second sampling was conducted around Lemieux Dome. A total of 28 samples (McGerrigle zone) and 25 samples (Lemieux zone) were collected.
Samples were analyzed for Cu, Pb, Zn, Ni, Co, Fe, Mn, Sb, Mo, Cr, Ag, Sn, As, Bi, W, Be and visual identification.
The data are published in Open File MB 85-09, Department of Energy and Resources, 1985.
