GOLD STANDARD INFILL AND STEPOUT DRILLING REPORTS MORE EXCEPTIONAL OXIDE RESULTS AT THE DARK STAR DEPOSIT
Gold Standard Ventures Corp. has released results from 31 reverse circulation (RC) and two core holes at the Dark Star deposit on its 100-per-cent-owned/controlled Railroad-Pinion project in Nevada's Carlin trend. Four holes in the northern portion of Dark Star intersected exceptional grades and thicknesses: 161.5 metres of 3.33 grams per tonne gold, 136.6 m of 3.36 g/t Au, 112.8 m of 1.42 g/t Au and 92.9 m 1.22 g/t Au, respectively. These results continue to confirm the lateral and strike continuity of higher-grade gold, and the openness of this system to the north, west and at depth.
To date 19,726 m of infill, stepout and geotechnical drilling have been completed in 121 RC and core holes at Dark Star. With this news release, results have now been reported for 80 of the 121 holes that have been completed. Results from another 33 Dark Star holes are summarized below.
Jonathan Awde, chief executive officer and director of Gold Standard, commented: "This year's drilling at Dark Star is transforming our understanding of the opportunities we have at Railroad-Pinion. We knew that, in Dark Star, we had an unusually high-grade oxide gold occurrence and the new results have confirmed this conclusion. But this drilling is taking us well beyond the current resource limits at Dark Star and also beyond our expectations for the district as a whole. The deeper zones of oxidized high-grade mineralization have surprised us. We are now revising the current program to further test the depth potential in those areas where the structural plumbing system appears to support it. The results could have important implications for the future development of the district."
Key highlights from Dark Star:
-
In the northern portion of Dark Star, drill holes DR18-46, -47, -50, -83 and DC18-03 returned thick, high-grade gold intercepts that remain open at depth.
-
DR18-83, an RC hole approximately 30 m east of DS16-24 (97.3 m of 3.16 g/t Au -- see Oct. 13, 2016, news release), intersected 161.5 m of 3.33 g/t Au
including 7.6 m of 5.40 g/t Au and 33.5 m of 6.48 g/t Au. These results outperform what was predicted in the resource block model by extending oxide gold mineralization closer to the current topographic surface and below the current resource model by approximately 35 m.
The oxide intercept is open at depth, where the hole bottomed in 2.11 g/t Au at 274.3 m.
-
Core hole DC18-03 intersected 136.6 m of 3.36 g/t Au, including three significantly higher-grade zones of
23.4 m of 5.35 g/t Au, 10.5 m of 4.86 g/t Au and 30.3 m of 6.67 g/t Au. These results outperform what was predicted in the resource block model by extending oxide gold mineralization closer to the current topographic surface and mineralization below the current resource model by approximately 65 m. Reduced mineralization occurs from 272.1 to 323.1 m as a discontinuous/irregular pod.
-
DR18-50 intersected 112.8 m of 1.42 g/t Au
including 18.3 m of 2.12 g/t Au and 24.4 m of 3.36 g/t Au. These results outperform what was predicted in the resource block model by confirming a thicker plus one g/t Au zone of oxide mineralization and extending oxide mineralization below the current resource model by approximately 30 m.
The intercept is open at depth, where the hole bottomed in 0.46 g/t Au at 196.6 m.
-
Currently in the northern portion of Dark Star, 18 drill holes end in gold mineralization below the current resource model. The extent of this open-ended mineralization measures approximately 250 m (north-south) by 100 m (east-west). These results provide an opportunity to expand the resource in the hangingwall and footwall of the Ridgeline fault, and at depth. Five drill holes, currently in progress, will assess the expansion potential.

Gold intervals reported in this table were calculated using a 0.14 g/t Au
cut-off.
Weighted averaging has been used to calculate all reported intervals.
True widths are estimated at 70 to 90 per cent of drilled thicknesses.
Don Harris, Gold Standard's senior development geologist, commented: "At the end of July, development drilling on Pinion and Dark Star was successfully completed (248 holes, 32,806 m) and we are now moving forward on incorporating the results into the Railroad-Pinion PEA. The PEA will evaluate the oxide deposit potential of the area, as well as give us the opportunity to convert inferred resources to measured and indicated. This is especially important for Dark Star, where currently 73 per cent of the resource is carried as inferred. Aside from the positive impacts the 2018 drill program will have on the PEA, results have also opened up Dark Star mineralization at depth, to the west and north, all well outside the current proposed Dark Star pits. These will be high-priority targets for follow-up drilling in the latter half of 2018 and into 2019."
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 project to the sample preparation facility was continuously monitored. A blank, certified reference material or rig duplicate was inserted approximately every 10th sample. The samples were delivered to Bureau Veritas Mineral Laboratories preparation facility in Elko, Nev., or American Assay Laboratories Inc. in Sparks, Nev., where they were crushed and pulverized. Resulting sample pulps were shipped to Bureau Veritas certified laboratory in Sparks, Nev., or Vancouver, B.C., or remained with American Assay Laboratories Inc. in Sparks, Nev. Pulps were digested and analyzed for gold using fire assay fusion and an atomic absorption spectroscopy (AAS) finish on a 30-gram split. Overlimit gold assays were determined using a fire assay fusion with a gravimetric finish on a 30-gram split. All other elements were determined by ICP analysis. Data verification of the analytical results included a statistical analysis of the standards and blanks that must pass certain parameters for acceptance to ensure accurate and verifiable results.
Drill hole deviation was measured by gyroscopic downhole surveys that were completed on all holes by International Directional Services of Elko, Nev. Final drill collar locations are surveyed by differential GPS (global positioning system) by Apex Surveying LLC of Spring Creek, Nev.
