Jul 31, 2017 (A Wilson) - Up to 230 ft. thick shallow dipping Cobalt Series sediments including Gowganda conglomerate up to 15 ft. thick at the base, greywacke up to 2 ft. and thick quartzite, unconformably overlie steeply dipping Keewatin volcanics; the sediments are faulted off against the volcanics in the south-east corner of the claim by the Cobalt Lake Fault which strikes northeast. The Contact Fault in the sediments dips 25ºSE parallel to and about 12 ft. above the volcanics-sediments unconformity; it strikes northeast. An important silver producing vein strikes north-west over the unconformity and below the Contact Fault; other silver veins also strike northwest. A rich smaltite- bearing vein occurs within the Cobalt Lake Fault.
