[{"type":"text","content":" MONTREAL, May 15, 2019 (GLOBE NEWSWIRE) -- Harfang Exploration Inc. (“Harfang”) (TSX-V: HAR) is pleased to announce that a new 2,755 linear km high-resolution heliborne magnetic survey reveals a 3.5 km long structural corridor along the Mista discovery (Cu-Au-Ag) on the Serpent Property (the “Property”) in the James Bay region of Québec (Figure 1). The Property is 100% owned by Harfang with no NSR. The survey sheds light on the link between magnetic features, mapped structures and nearby copper-gold-silver occurrences. Strongly motivated by this association, Harfang is set to resume exploration work on the Property in early June mainly guided by this new detailed magnetic survey. The high-resolution survey unveils two important structures identified from the magnetic discontinuities which are associated to mapped shear zones: a WNW-ESE trend (Mista structure) and an East-West trend (Viper structure). Both trends are overlapped by gold-bearing till anomalies (up to more than 30 g/t Au) (Figure 2). Recent analyses from rock samples of the Mista discovery (1.12% Cu, 0.23 g/t Au and 8.68 g/t Ag over 10 m [channel], see press release October 11, 2018), show mineralization has an anomalous content in bismuth (up to 125 ppm Bi) and tellurium (up to 18.2 ppm Te). A mineralogical study revealed that disseminated chalcopyrite and minor sulfides (pyrite and pyrrhotite) are mainly hosted in quartz veins cutting across foliated wacke and quartz-rich arenite (or quartzite) and foliated to gneissic tonalite. Mineralized quartz veins were deformed along a WNW-ESE shear zone (Mista structure). The Viper showing (up to 21.91 g/t Au) corresponds to quartz veining in a tonalite-hosted hematized shear zone striking into an East-West direction (Viper structure). Several rock samples collected in the surroundings of these showings returned anomalous gold (up to 0.3 g/t Au) and copper (up to 0.67%) values (Figure 2). Preliminary data interpretation also shows a potential for more discoveries along such multi-kilometer corridors which represent favorable grounds for future exploration development. The immediate area surrounding Mista and Viper deserves more intense fieldwork investigation. Upcoming exploration work will mainly consist in mechanical trenching of newly discovered copper, gold and silver occurrences, in prospecting and geol...
