Vancouver, Canada – September 5, 2017 – Aztec Minerals Corp. (AZT: TSX-V) announces that the first two trenches at the Jasper prospect on the Cervantes property in Sonora State, Mexico have returned attractive gold and copper grades.
The Penasco trench returned a weighted average of 0.89% copper and 0.59 grams per tonne (gpt) gold over a 20 meter (m) width and the Cardon trench, 30 m north of the Penasco trench, assayed a weighted average of 0.76% copper and 0.30 gpt gold over a 10.85 m width, both still open in all directions. The Penasco trench copper values range between 0.35% and 1.39% and the gold values range between 0.05 and 2.95 gpt. The Cardon trench samples range between 0.35% and 1.05% copper and 0.09 and 0.778 gpt gold.
Trenching exposed widespread oxide copper mineralization, including neotocite, chrysocolla and minor chalcocite. Oxide gold mineralization is associated with hematite-goethite formed from oxidized pyrite in sub-vertical siliceous structures, quartz-copper oxide veins, and densely spaced fractures.
New trenching is underway to connect the Penasco and Cardon trenches, and extend further north to connect with other rock outcrops mineralized with copper oxides. Hand trenching will continue south of the Penasco trench to outcrops where grab samples have assayed up to 2.47% copper and 0.16 gpt gold. Overall, oxide copper has been traced in outcrop for over 230 m along the north-south Jasper trend, open in all directions and extending under thin overburden cover. Visible gold has been subsequently been observed in new trenches, with assays pending.
