The target comprises a 1 kilometre by 2 kilometre aeromagnetic anomaly on the western side of its 100%-owned La Balsa property located 15 kilometres north of the Port of Lazaro Cardenas, Michoacan, Mexico.\nDrillhole MM-322, the first of three drillholes designed to test the buried porphyry target, was completed at a total depth of 661 meters after cutting long intervals of monzonite porphyry carrying strong disseminated pyrite mineralization overlying a 180-meter interval carrying multiple thin stringers of chalcopyrite.\n\nSignificant exploration milestones achieved with this drillhole include:\n\n\n >\n\n\nMineralization in the upper half of drillhole MM-322 consisted of abundant disseminated to blebby pyrite hosted by xenolith-rich monzonite porphyry and andesitic wallrock. In contrast, the lower half of the drillhole contained more modest amounts of pyrite and nearly all of the chalcopyrite stringers that were observed. Chalcopyrite was most abundant between depths of 378 meters and 558 meters beneath a prominent shallowly dipping fault that was cut at a depth of 376 meters. This fault is believed to be the downdip projection of a major thrust fault that truncates the bottom of the oxide copper breccia resource (La Virgin) one kilometre to the east. White rhyolite ash tuff that occupies the fault zone in MM-322 is visually as well as chemically identical to a white rhyolite ash tuff that occupies the thrust fault at the base of the La Virgin oxide copper breccia body. These observations provide confirmation of the thrust fault model, which is expected to provide predictive capability in the siting of future drillholes to explore the roots of specific known breccia bodies in the upper plate of the fault.\nMore than half of MM-322 was drilled through nonmagnetic monzonite porphyry, which is also the principal host rock of the Company's copper breccia mineral resource to the east. Widespread destruction in MM-322 of primary magnetite in the monzonite po...
