Keymet is a high priority precious metal - base metal property, located in northeast New Brunswick near Bathurst. The property covers an area of approximately 3400 hectares. Polymetallic veins (copper, lead, zinc and silver) were mined during the 1950s in the northern region at the Keymet Mine. Historic exploration by multiple companies dates back to the late 1800’s with multiple mineralized veins discovered in the northern region, including the historic Keymet Mine. This included multiple diamond drilling programs. Reported 1980s drill intersections in the northwest at the Elmtree 12 vein system included 11.4% Zn, 7.7% Cu and 13.6 oz. / ton Ag over 0.88 meters and 16.4% Cu, 10.1% Zn and 31.0 oz. / ton Ag over 1.22 meters. Great Atlantic conducted diamond drilling at this vein system in 2015, intersecting 16.68% Zn, 1.11% Cu and 152 g/t Ag over 1.80 meters and 8.68% Zn, 0.29% Cu and 44 g/t Ag over 4.28 meters. Great Atlantic discovered gold-bearing boulders near these drill intersections with boulder sample assays up to 51 g/t Au. Trenching by Great Atlantic in 2012 in this area intersected a gold bearing shear zone of which channel samples across the zone graded 1.09 g/t Au over 11.8 meters. Host rocks in this area are meta-sediments. A regional northwest trending fault occurs in this region. Some rocks are referred to as tectonic melange.
Gold bearing zones occur west of the Keymet property on an adjacent property. NI 43-101 compliant resources have been reported for these gold bearing zones (indicated and inferred resources of 294,000 ounces gold as per 2012 report). Great Atlantic has no interest in this adjacent property.
