The Bourlamaque Zone is located on the central portion of the Bourlamaque synvolcanic Batholith. Late dioritic dykes cross cut the batholith and control the deformation and gold-bearing quartz-tourmaline vein network systems. There are numerous gold mines hosted in this intrusion, including the Beaufor mine, which is currently in production and has produced over 1.2 million ounces.
Three past producing gold mines Dumont, Ferderber, and Lac Herbin are located on QMX Gold’s portion of the Bourlamaque Batholith. The total production from these 3 mines has been reported as 4.1Mt grading 6.0 g/t Au for 792 650 ounces (NI 43-101 The Aurbel Group Properties, July 25th 2017 by David Rigg, P.Geo).
