09/30/2019 (T Pettigrew) - The metavolcanics as observed from prospecting are generally massive siliceous flows usually containing minor sulphide mineralization. In certain areas, the metavolcanics are less massive and more sheared, siliceous and sometimes altered to various degrees with chlorite, sericite and iron carbonate. The areas generally have increased and varied sulphide deposit, namely pyrite and chalcopyrite. Within the metavolcanic shearing, quartz veins and stringers have intruded the seams and are usually narrow, with maximum width witnessed being roughly 3 feet. Various iron formation zones have been located. The largest magnetite iron formation contains fine disseminated pyrite, massive in certain areas and reaches a width of 6 feet and outlines strike at 75 feet. Adjacent to the iron formation is a 10" wide quartz vein hosted in rusty, highly sheared metavolcanics. The vein and wall rock are abundantly mineralized with pyrite and lesser amounts of chalcopyrite. Roughly 50 feet further south exposed is a pillow breccia zone. The contact between IF zone and the pillow breccia zone is covered by overburden and has not been observed directly. The pillow breccia zone contains highly silicified fragments and silicified altered pillows. The whole zone contains very fine disseminated pyrite and chalcopyrite up to 3% with the fragmental pieces containing more pyrite. This zone is outlined for a width of 100 feet (Assessment report 52H09SE2001).
