Oct 29, 2021 (Therese Pettigrew) - Gold mineralization on the Randall Lake property is associated with sheared mafic volcanics and iron formation in the North Caribou River Fault. The mineralization occurs were fault-related deformation is associated with quartz-carbonate-sulphide veining or pervasive epigenetic sulphide mineralization. DDH KE-90-3 returned 0.594 g/t Au over 2.5 feet (0.76 m) from a brecciated conglomerate and wacke with fuchsite and disseminated to banded or massive arsenopyrite, and 0.437 g/t Au over 1.2 feet (0.36 m) from a brecciated dolomite-quartz vein with fuchsite and semi-massive to massive arsenopyrite (Assessment report 53B14NE0004).
