The chain of custody from Gold Standard's Elko, NV warehouse to the sample preparation facility in Reno, NV was continuously monitored. Sampling Methodology, Chain of Custody, Quality Control and Quality Assurance:Īll sampling was conducted under the supervision of the Company's chief geologist and consulting metallurgist Sevket Acar. Column leach and comminution tests on composites from representative core holes are planned to begin in the second half of this year and will help determine the details of the processing of oxide material at Pinion." Gary Simmons, Gold Standard's consulting metallurgist stated: "Metallurgical work at Pinion is off to a good start with cyanide soluble and bottle roll characterization studies indicating that a significant percentage of the gold within the oxidized collapse breccia host at Pinion is recoverable using cyanide leach processing. These results will guide location and selection of future composites for column leach testing, the next step in the metallurgical characterization process.Įxcellent correlation exists between the visual logging of oxidized zones containing hematite and/or limonite in drill samples, the cyanide soluble gold assays and now the bottle roll results.Īverage recoveries of gold in different areas of the Pinion deposit are illustrated on the supporting image which may be viewed by clicking the following link. The bottle roll characterization results confirm the consistently oxidized nature of gold mineralization throughout the Pinion deposit. In most holes, at least two composites were made up from commonly continuous intercepts. The average down-hole length of composited gold intercepts was 14.6 meters, made up of 10 individual drill samples. The composites are from a wide distribution of gold intercepts in 42 reverse-circulation drill holes and four core holes completed by Gold Standard across the Pinion deposit. These averages are from bottle roll test results on 99 composite samples analyzed at both mesh sizes. Jonathan Awde, CEO and Director of Gold Standard, commented: "We are very pleased by these test results which represent another important step forward in the process of demonstrating the economic potential of Pinion as an oxide heap leach deposit."Īverage gold recoveries, weighted by calculated head grades of the composites, were 69.2% for material crushed to 10 mesh size and 80.3% for material crushed to the finer 200 mesh size. Simmons has more than 35 years of experience with mining companies including Newmont Mining Corporation where he was Senior Technical Director of Metallurgy and Technology. ![]() The bottle roll study was completed by Kappes Cassiday & Associates (KCA) in Reno, Nevada and reviewed by consulting metallurgist Gary Simmons. Results from this work were used to design the bottle roll characterization testing. Cyanide soluble gold recoveries averaged 82.4% in oxidized multilithic dissolution collapse breccia, the main gold host at Pinion, indicating that this material was likely to support heap leach processing (see Augnews release). In 2015, Gold Standard completed the first ever comprehensive work designed to determine the metallurgical characteristics of the Pinion oxide gold deposit. ( TSX VENTURE:GSV) (NYSE MKT:GSV) ("Gold Standard" or the "Company") today reported that a comprehensive bottle roll cyanide leach program on its 100%-owned Pinion oxide gold deposit in the Carlin Trend, Nevada, returned weighted-average gold recoveries of 69.2% for 10 mesh material and 80.3% recovery for 200 mesh material. ![]() VANCOUVER, BRITISH COLUMBIA-(Marketwired - Jul 12, 2016) - Gold Standard Ventures Corp. ![]()
