Gold Recoveries Averaging 86.5% For Dark Star Oxide

VANCOUVER - Gold Standard Ventures Corp. reported highly encouraging metallurgical results from continuing work designed to determine the processing characteristics of the Dark Star oxide gold deposit, on its 100%-owned/controlled Railroad Project in Nevada’s Carlin Trend. Column recoveries from -12.5 mm size material averaged 86.5% for Dark Star oxide and 70.0% for partially oxidized transitional material. These results confirm that Dark Star material is likely to support heap leach processing.

Column testing for gold cyanide leachability of Dark Star core samples was completed by Kappes Cassiday and Associates of Reno, Nevada, under the direction of Gary Simmons, consulting metallurgical engineer. According to Mr. Simmons: “Data from metallurgical column testing to date at Dark Star point to high gold leach extraction from oxidized and transitional materials and suggest that simple heap leaching of crushed and/or run of mine material appears to be the preferred process option at Dark Star.”

Jonathan Awde, CEO and Director of Gold Standard commented: “Step by step we are increasing the value of our Railroad Project by reducing risks and establishing the viability of its gold deposits. The recovery rates in these tests are beyond our expectations. We now know how the gold can be recovered at Dark Star and that crushing requirements and reagent consumption are favorable. The next step is to complete a PEA defining economic parameters.”

A total of 40 drill core composites, representative of the gold deposit were column tested. All 40 samples were crushed to reduce 80% of the material (known as P80) to a size of 12.5 mm or less. Splits from five of the composites were also tested at a column feed size of P80 of 25 mm. Gold extraction for oxide material ranged from 66-95%, with an average gold extraction of 86.5% while transitional material gold extraction ranged from 58-90% with an average gold extraction of 70%.
