NR aurcana Vancouver, BC, April 3, 2013- Aurcana Corporation ("Aurcana" or the "Company") (TSXV: AUN, OTCQX: AUNFF) is pleased to announce the results of the 2012 exploration program at the Shafter Mine.
The 2012 exploration program at Shafter has identified evidence for a larger and more complex mineralizing system than previously recognized, with multiple discrete pulses of silver, silver lead-zinc, lead-zinc mineralization and over-printing silicification.
Dr. Peter Megaw, consulting geologist for Aurcana Corporation states: "Having evidence of complex, multiple stages at Shafter confirms we are exploring in a system with high potential, while demonstrating that although we still have not zeroed in on where to focus, continuing to do so is more than warranted. Seeing high complexity is a positive indicator for a long-lived, multi-staged, large system."
The main activity of the 2012 Shafter exploration program was an aggressive diamond drilling campaign focused on the near mine environment that totaled 36,000 feet in twenty-nine holes. A detailed map is available at: www.aurcana.com.
Drill holes were long angled holes designed to bend under known mineralization seeking evidence of a plumbing system and to look for additional potential in previously untested, deeper, limestone units. Major regional and mine structures were targeted. Eleven holes intersected mineralization in the Shafter and Presidio Mine horizons and provided additional infill data for the mine model.
In the Presidio Mine the drill program identified a major east-west trending structure (Herculano) that exhibits strong evidence of fluid movement and multiple dikes proximal to historic workings, which contain significant mineralization. Sulphide-bearing, strongly silicified breccia bodies are present that are cross-cut by later structurally controlled mineralization. These features suggest a prolonged geologic history of multiple episodes of structural re-adjustment, with multiple phases of mineralization and silicification. Further investigation is warranted to clarify if the structure is a feeder to the adjacent Santiago manto at Presidio.
