GOLD STANDARD INTERSECTS 149.4M OF 1.38 G AU/T 510M NORTH OF THE DARK STAR OXIDE GOLD DEPOSIT, CARLIN TREND NEVADA
Gold Standard Ventures Corp. has released assay results from five reverse circulation (RC) holes drilled in the 2015 phase 2 program at the Dark Star oxide gold deposit on its 100-per-cent-owned/controlled Railroad-Pinion project in Nevada's Carlin trend. Four of the five holes returned significant intercepts containing gold values above the cut-off grade of 0.14 gram per tonne (g/t) gold (Au) established by Apex Geoscience Ltd. of Edmonton, Canada, in its Dark Star National Instrument 43-101 resource estimate announced on March 3, 2015 (see news release). Results include multiple oxide intercepts grading above one gram per tonne and are highlighted by a thicker zone of 149.4 metres of 1.38 grams gold per tonne (g/t Au).
The DS15-10 intercept represents the discovery of a new gold zone that is thicker and higher grade by an order of magnitude than anything drilled to date at Dark Star.
Jonathan Awde, chief executive officer and director of Gold Standard, commented: "These results fundamentally change the character and potential of the Dark Star deposit. In the short term, we anticipate significant resource expansion at Dark Star. In the bigger picture, we now see the Dark Star structural corridor emerging as a major feature of the district that could extend for many hundreds of metres north and south of the known resource."
Drilling also continues on the Pinion deposit and the North Bullion deposit. Additional targets are also being evaluated.
Key highlights of the Dark Star phase 2 program include:
DS15-10 intersected a vertically extensive gold zone including an upper oxidized intercept of 149.4 m of 1.38 g/t Au and a lower reduced intercept of 18.3 m of 0.84 g/t Au. These intercepts are located 510 m north of the Dark Star maiden resource in an area with no historic drilling. The DS15-10 mineralization represents the thickest and highest-grade gold zone intersected in drilling to date at Dark Star. The upper gold intercept is hosted in an oxidized limonite- and hematite-bearing, variably silicified and quartz-veined, bioclastic conglomerate unit. This is the same host unit as the Dark Star deposit. Gold intercepts are open in multiple directions.
DS15-06 intersected multiple zones of oxidized gold mineralization including 74.7 m of 0.58 g/t Au approximately 30 m north of the Dark Star maiden resource. These intercepts are open in multiple directions.
DS15-09 intersected 29.0 m of 0.73 g/t Au approximately 650 m north of the Dark Star maiden resource. This shallow intercept, beginning at 37 m, is in oxidized rock and open in multiple directions.
Intercepts in DS15-06, 09 and 10 confirm the upside exploration and expansion potential within the Dark Star structural corridor, north of the Dark Star maiden resource. The six-kilometre strike length of the Dark Star corridor remains largely untested. GSV completed mapping, geochemistry, gravity and CSAMT in the company's phase 1 2015 program to identify targets within this large corridor. The phase 2 drilling program will be expanded to follow up on these outstanding oxide gold drill results.
The phase 2 Dark Star drilling was designed to extend areas of known gold mineralization along the strike of the Dark Star structural corridor to the north of DS15-03, a phase 1 drill hole that intersected two zones of gold mineralization including 32.0 m of 0.58 g/t Au and 21.3 m of 1.90 g/t Au (see news release dated July 28, 2015). Gold at Dark Star occurs in an unconventional host rock for the Carlin trend, a Pennsylvanian-Permian unit composed of bioclastic-bearing debris flow conglomerate with interbeds of calcareous sandstone, siltstone and mudstone. These rocks dip to the west within the north-trending Dark Star corridor, which is bounded to the east by a large displacement normal fault.
To date, phase 2 includes 2,473 m of RC drilling in six holes at Dark Star that indicate the gold system extends northward along the Dark Star structural corridor into favourable geologic terrain that has not been systematically drill tested. Results for DS15-06 through DS15-10 are summarized in the associated table. Results of the sixth hole, DS15-11, an angle hole approximately 61 m updip from DS15-10, are pending.
Mac Jackson, Gold Standard's vice-president of exploration, stated: "With these results from DS15-10, Dark Star becomes the fourth target to produce outstanding intercepts at our Railroad-Pinion project, joining Pinion, North Bullion and Bald Mountain. The pace of discovery is quickening as we gain command of the geology and further refine the tools that have proved to be most effective. This is the way successful exploration progresses on the Carlin trend; momentum builds as gold is intersected in multiple targets within these large mineral systems. The thick, oxide intercept in DS15-10 has changed our expectations of Dark Star. This hole remains open in multiple directions and we are confident of drilling more like it."

Sampling methodology, chain of custody, quality control and quality assurance
All 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. A blank or certified reference material was inserted approximately every 10th sample. The Dark Star samples were delivered to Bureau Veritas Mineral Laboratories preparation facility in Elko, Nev. The samples are crushed, pulverized and sample pulps are shipped to Bureau Veritas certified laboratory in Sparks, Nev. Pulps are digested and analyzed for gold using fire assay fusion and an atomic absorption spectroscopy (AAS) finish on a 30-gram split. All other elements are determined by ICP analysis. Data verification of the analytical results includes a statistical analysis of the duplicates, standards and blanks that must pass certain parameters for acceptance to insure accurate and verifiable results.
Pulps from the significant intervals in DS15-10 were also delivered to ALS Minerals preparation facility in Reno, Nev., for verification assay of the original Bureau Veritas gold assays. ALS Minerals certified laboratory in Reno digested and analyzed the pulps for gold using fire assay fusion and an atomic absorption spectroscopy (AAS) finish on a 30-gram split. Results of the ALS Minerals gold fire assay confirm the original Bureau Veritas gold assays.
