The Fyre Lake volcanogenic massive sulphide (VMS) copper-cobalt-gold property is situated 160 kilometres northwest of Watson Lake in the Finlayson Lake area of the Yukon-Tanana Terrane. Columbia Gold Mines Ltd. conducted an integrated exploration program there between late June and early October, 1996. The Fyre Lake property is underlain by a sequence of metamorphosed sedimentary and volcanic rocks known as the Layered Metamorphic Sequence (LMS). Copper-cobalt-gold VMS mineralization within the Kona Creek cirque area is hosted by deformed and metamorphosed chlorite-actinolite-quartz schist of the middle unit of the LMS which is interpreted to be a succession of basic to possibly intermediate flows with intercalated volcaniclastics and volcanically-derived fine-grained sedimentary rocks. These rocks are structurally overlain by a thick sequence of phyllitic metasedimentary rocks with a basal unit of micaceous quartz-chlorite-mica schist. The copper-cobalt-gold (± zinc, silver) VMS mineralization within the central portion of the Kona deposit occurs in three distinct horizons of massive to semi-massive sulphide and magnetite mineralization over a combined thickness of 70 to 80…
