GOLD STANDARD REPORTS INFILL DRILLING SUCCESS AT THE DARK STAR OXIDE GOLD DEPOSIT, CARLIN TREND, NEVADA
Gold Standard Ventures Corp. is providing the status of the 2018 infill drilling program at the Dark Star and Pinion oxide gold deposits on its 100-per-cent-owned/controlled Railroad-Pinion project in Nevada's Carlin trend. Two reverse circulation and two core rigs have completed 4,605 metres of infill drilling in 28 infill holes in the northern portion of Dark Star. These four rigs have now moved to the Pinion deposit where 5,450 m of infill drilling have been completed in 62 holes. Results from 25 Dark Star holes are summarized in the table.
This year's $25.8-million (U.S.) program includes an estimated 74,800 m of RC and core drilling in 381 holes (see Feb. 26, 2018, news release). Infill and development work at Dark Star and Pinion is expected to account for approximately 40,800 m of drilling in 296 holes while exploration should add another 34,000 m of drilling in 85 holes. The 2018 program objectives are:
- Infill and development drilling at the Dark Star and Pinion oxide gold deposits to reduce drill spacing to approximately 30 m; convert inferred resources to the measured and indicated categories; and define the limits of the gold zones, some of which could be expanded by the program;
- Exploration drilling at Jasperoid Wash to test new high-priority targets and to reduce drill spacings and provide requisite data for a maiden resource estimate by the end of 2018. It is important to note that from Gold Standard's first 2017 Jasperoid Wash drill hole to a maiden resource estimate, this process will be completed in approximately 14 months;
- Drilling to test new high-value targets at Dixie, the Dark Star corridor, Ski Track and elsewhere within the Railroad district.
Jonathan Awde, chief executive officer and director of Gold Standard, commented: "This is a very aggressive program designed to generate the data for a revaluation of the Railroad-Pinion project. Over the past four years, we have demonstrated that the small Pinion deposit we acquired in 2014 was just a part of a much larger Carlin system. We have added discoveries, expanded them and proved that they are metallurgically receptive to high recoveries using heap-leach technology. We aim to confirm this year that Railroad-Pinion can be the next successful mine on the Carlin trend."
Key highlights from Dark Star:
-
On the western side of Dark Star, DR18-06 intersected 53.4 metres of 0.92 gram per tonne gold,
including 6.1 of 2.47 g/t Au;
and 77.7 m of 1.57 g/t Au,
including 9.1 m of 4.74 g/t Au. DR18-07 intersected 132.6 m of 0.63 g/t Au,
including 16.8 m of 1.58 g/t Au. These results, along with results in DR18-04 and DR18-05, outperform what was predicted in the resource block model by extending gold mineralization below the current resource model and to the west of the Ridgeline fault.
- DR18-19 intersected 126.5 m of 1.18 g/t Au,
including 25.9 m of 2.43 g/t Au. This intercept is thicker than predicted by the resource block model.
-
DR18-08 intersected 80.8 m of 1.56 g/t Au,
including 27.4 m of 3.03 g/t Au. This intercept is higher grade than predicted by the resource block model.
- In March, the company bought down a strategic net smelter royalty (NSR) from 5 per cent to 2 per cent. The NSR covers portions of the Dark Star and Pinion gold deposits.
Dark Star drill results are as shown in the table.

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.
* Results from the lower half of DS17-36 returned additional zones of
mineralization beneath the original intercept of 73.0 m of 1.60 g/t Au,
including 25.8 m of 3.25 g/t Au (see Jan. 23, 2018, news release).
DS17-36 is approximately 165 m south of DS17-37 (141.8 m of 3.32 g/t
Au, including 25.9 m of 8.63 g/t Au -- see Jan. 23, 2018, news release).
These results confirm the resource block model.
DR18-01 and DR18-02 to the north, and DR18-03, DR18-11 through DR18-14, encountered no significant mineralization and confirm the known limit of the gold zone on the northeast and east sides of the deposit. These results were as expected based on the current resource model.
Don Harris, Gold Standard's senior development geologist, stated: "The infill program at Dark Star and Pinion is rapidly progressing during the first half of 2018. We are excited about this new chapter in GSV history, as drilling steps from exploration to development. Reducing drill spacing is critical for producing a measured and indicated resource for utilization in prefeasibility work on the project. Results to date have confirmed or exceeded our model expectations."
Sampling methodology, chain of custody, quality assurance/quality control
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 or certified reference material was inserted approximately every 10th sample. The samples were delivered to Bureau Veritas Mineral Laboratories preparation facility in Elko, Nev., where they were crushed and pulverized. Resulting sample pulps were shipped to Bureau Veritas certified laboratory in Sparks, Nev., or Vancouver, B.C. Pulps were digested and analyzed for gold using fire assay fusion and an atomic absorption spectroscopy (AAS) 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 down hole surveys that were completed on all holes by International Directional Services of Elko, Nev. Final collar locations are surveyed by differential GPS by Apex Surveying LLC of Spring Creek, Nev.
