Mar 10, 2014 (A Wilson) - Ore grade lenses within the zone have been traced 2500 ft vertically and for 1300 ft horizontally and the lenses range in width up to 125 feet and in length up to 600 ft. Most lenses strike east and dip steeply. A 120 m wide zone, characterized by extensive pyrititzation, contains disseminated chalcopyrite-bornite mineralization and minor tetrahedrite, tennantite, molybdenite and native silver. Ore grade material is confined to a number of shoots in a zone 360 long and 90 m in width.
