Gold Standard Reports Increased Grades From Check Fire Assays of Several Previously Reported Intercepts From the Dark Star Oxide Gold Deposit

 

 

VANCOUVER, BC - Gold Standard Ventures Corp. reported favorable results from a check assay program for the North and Main Dark Star deposits on its 100%-owned/controlled Railroad-Pinion Project in Nevada's Carlin Trend. A comprehensive assay check (umpire) program was completed by ALS Chemex (ALS) on original drill hole sample pulps from the Company's 2015 and 2016 drilling at the Main and North Dark Star deposits which had reported values at or above the 0.14 g Au/t cut-off grade established in the NI 43-101 resource estimate announced on March 3, 2015 (see news release). In total, ALS assayed 1,838 drill sample pulps from 37 drill holes distributed throughout the North and Main Dark Star deposits using the Au-AA23 method. ALS assays confirmed, verified and, in certain instances, increased the gold grade from the original Bureau Veritas (BV) gold fire assays.

Additionally, metallurgical core holes DS16-17 and DS16-20 were completed at the Main Dark Star deposit to provide samples for column leach testing.

Jonathan Awde, CEO and Director of Gold Standard commented: "We are quickly moving ahead with our plans to support a premium valuation for the Dark Star area. This thorough check assay program is an important step towards preparing a new resource estimate for the Dark Star area which will include the most recent drilling at Main Dark Star and North Dark Star. Our drilling last year established that these two deposits connect and we therefore expect the new resource estimate will report a total for greater Dark Star. At the same time, we are proceeding with more advanced metallurgical testing following last week's positive announcement on the cyanide solubility of Dark Star oxide gold mineralization."

All original sampling was conducted under the supervision of the Company's project geologists and the chain of custody from the drill to the sample preparation facility was continuously monitored. Core was cut at the company's facility in Elko and one quarter was sent to the lab for analysis and the remaining core retained in the original core box. A pulp-blank or certified reference material was inserted approximately every tenth sample. The Dark Star core samples were delivered to Bureau Veritas Mineral Laboratories preparation facility in Elko, NV. The samples are crushed, pulverized and sample pulps are shipped to Bureau Veritas certified laboratory in Sparks, NV or Vancouver, BC. Pulps are digested and analyzed for gold using fire assay fusion and an atomic absorption spectroscopy (AAS) finish on a 30 gram split. Data verification of the analytical results includes a statistical analysis of the standards and blanks that must pass certain parameters for acceptance to insu re accurate and verifiable results.

Original pulps for the check assay program were delivered to the ALS certified lab in Sparks, NV, where the pulps were digested and analyzed for gold using fire assay fusion and an atomic absorption spectroscopy (AAS) finish on a 30 gram split (Au-AA23 method and the Au-GRA21 method for those samples that were over 10 g Au/t requiring a gravimetric finish). Following the ALS fire assays, the original sample pulps from mineralized zones in DS15-10, DS16-03B and DS16-08 were shipped to SGS certified lab in Burnaby, BC where the pulps were digested and analyzed for gold using fire assay fusion and an atomic absorption spectroscopy (AAS) finish on a 30 gram split (FAA313 method and the FAG303 method for those samples that were over 10 g Au/t requiring a gravimetric finish).
