04/30/2020 (T Pettigrew) - On island 405, a carbonate zone containing many quarts stringers, disseminated cube pyrite, and minor arsenopyrite, was found to contain minor gold values. One sample containing some arsenopyrite assayed 0.10 oz/t Au (Assessment report 52G13NW0047). A grab sample collected by Golden Range Resources Inc. in 1983 returned 0.173 oz/T Au (5.38 g/t Au) from a four foot wide quartz-carbonate stockwork trending 080/N. The altered mafic metavolcanics contained up to 30% pyrite (Assessment report 52G13NW0005). DDH MN-10 returned assays up to 8.11 ppm Au over 0.28 m from a quartz vein in an intermediate-mafic metavolcanics. The vein contained disseminated pyrite and up to 5% pyrite rimming the vein (Assessment report 20000013532).
