Feb 23, 2021 (Therese Pettigrew) - The Swamp Lake showing is associated with a N70 E structural lineament and consists of a massive, strongly carbonatized, mafic metavolcanic rock unit hosting parallel quartz-carbonate veins (10 cm to 25 cm wide). The host volcanic rock also displays upwards to 10 per cent ubiquitous arsenopyrite mineralization. Rock grab samples and channel samples provided the following anomalous to economic gold assay values: 170 ppb, 290 ppb, 680 ppb, 990 ppb, 10,000 ppb (0.30 oz/t Au) and >10 000 ppb (0.30 oz/t Au) (Mason et al., 1990).
