MONTREAL, QUEBEC--(Marketwired - Aug. 10, 2017) - Midland Exploration inc. ("Midland") (TSX VENTURE:MD) is pleased to announce the discovery of a new high-grade massive sulphide zinc showing, as part of its strategic exploration alliance with Altius Minerals Corporation ("Altius") (TSX:ALS). The new showing, named "O'Connor" is located approximately 80 kilometers east of Nemaska, Eeyou Istchee, Quebec, in an under explored area. Mineralization ranges from coarse grained sphalerite in quartz 'exhalite' that returned 7.53% Zn and 4.5 g/t Ag to massive coarse pyrrhotite-pyrite-sphalerite that returned up to 2.79% Zn and 4.4 g/t Ag in grab samples (note that grab samples are selective by nature and values reported may not be representative). One pyritic massive sulfide also returned 0.09% Co and 6.8 g/t Ag from grab samples. The mineralization is interpreted as the distal part of a volcanogenic massive sulfide system. The mineralized horizon was traced over 150 meters and remains open along strike both west and east.
