Jun 08, 2016 (A McKee) - At East Lake mineralization is associated with quartz-tourmaline veining in mafic volcanic rocks. The veins are typically 2-5 cm wide and up to a metre long where they are oriented parallel to the east trending foliation. Smaller, subsidiary veinlets cross-cut the foliation at a high angle. The wall rock around the veins is weakly altered (phyllic?) and appears bleached, with secondary carbonate and minor fine-grained pyrite and magnetite. Two samples of the veins were found to have gold concentrations of 0.489 ppm and 0.328 ppm.
