Turmalina Metals Corp. Provides Update on the Colquemayo Project
Turmalina Metals Corp. provided an update on the Company's recently announced Option to acquire 100% of the Colquemayo Project in Peru (the "Option"). Highlights of the colquemayo Project: Epithermal and porphyry copper-silver-gold exploration project in Moquegua Province, Southern Peru. Historic drill results include an intersection that returned: 237.3 m at 2.4% Cu, 0.08 g/t Au & 10 g/t Ag, including 161.2 m at 3.4% Cu, 0.09 g/t Au & 14 g/t Ag and 31.3 m at 14.8% Cu, 0.2 g/t Au & 47 g/t Ag. Exploration will also focus on areas in the property outside the three centres of hydrothermal alteration identified and drill tested to date. In some of these areas argillic and advanced argillic alteration have been recognized locally, with limited exposure because of overlying lower temperature alteration assemblage (chlorite, epidote and carbonate). These areas may represent less eroded parts of epithermal systems, with potential for definition of new hydrothermal centres for initial drilling. Additional geophysics to cover the remaining part of the property will also be considered. Colquemayo alteration mapping: Three lithocaps (Amata-Cairani, Coripuquio and Yanarico) were explored between 2009 and 2014 by Rio Tinto and Buenaventura. The road accessible Colquemayo Cu-Ag-(Au) Project lies between 4,300 and 4,800 masl and is located in General Sanchez Cerro province in Moquegua department, near the border with the Arequipa department, in southern Peru. The project is situated in the late Miocene to Pliocene epithermal belt to the east of the productive Cu-Mo Paleocene to Eocene porphyry belt hosting the copper mines of Cerro Verde, Cuajone, Quellaveco and Toquepala, and to the west of the Au-Ag Late Miocene to Pliocene epithermal belt with important projects and mines such as San Gabriel, currently under construction, and the Aruntani mining district (>2 Moz Au produced). Previous work by Rio Tinto and Buenaventura between 2003 and 2014 includes 27,000 m of diamond drilling across 80 holes, detailed geological mapping and intensive surface geochemistry with 9,800 rock chip and 1,500 channel samples. Detailed topography (1 m resolution) and geophysical surveys (magnetometry, chargeability and resistivity) have been completed at two of the hydrothermal centres identified to date. Alteration mapping shows the zonation typical of a high-sulphidation epithermal system including argillic alteration with kaolinite and dickite, advanced argillic alteration with quartz and alunite, and some deeper pyrophyllite zones, along with zones of massive and vuggy silica. Several phreato-magmatic and hydrothermal breccias with significant gold values have been identified. Several kilometer scale hydrothermal targets have been identified to date namely the Amata, Cairani, Coripuquio, and Yanarico which represent exceptional exploration targets for Turmalina.
