Gold Standard Infill and Step-Out Drilling Reports Exceptional Results and Resource Expansion Potential at the Dark Star Deposit

 

 

 

 

 

Gold Standard Ventures Corp. (TSX:GSV) (NYSE AMERICAN:GSV) today reported results from 19 reverse-circulation drill holes at the Dark Star deposit on its 100%-owned/controlled Railroad-Pinion Project in Nevada’s Carlin Trend.  The exceptional results confirm that the Dark Star Deposit may be emerging as a major Carlin gold occurrence where a larger-than-expected Ridgeline Fault System has played a significant role in concentrating higher grade gold.

 

 

To date, 17,624m of infill, step-out and geotechnical drilling have been completed in 105 RC and core holes at Dark Star (refer to Dark Star plan map at the following link – https://goldstandardv.com/lp/ds-jul17-2018-drill-maps/).  With this news release, results have now been reported for 47 of the 105 holes that have been completed.  Results from another 19 Dark Star holes are summarized below. 

 

 

Jonathan Awde, CEO and Director of Gold Standard commented: “Essentially, our infill drilling campaign has morphed into fresh exploration. As is the norm for infill work, we are drilling to find the limits of the deposit and we are frequently not finding the limits, laterally and especially at depth. For the most part, past work at Dark Star focused on the shallow part of the system.  We now believe significant expansion is likely at depth. It appears that the known surface deposits could potentially progress into deeper high-grade underground deposits coinciding with robust fault structures such as the Ridgeline system. Follow-up drilling is planned to pursue these exciting concepts in the current program.”

 

 

Key Highlights from Dark Star:

 

  • Drill holes DR18-43, -44 and -45 returned thick, high-grade oxide gold intercepts that remain open at depth.
  • DR18-43, an RC hole approximately 50m east of DS17-37 (8m of 3.32 g Au/t, including 25.9m of 8.63 g Au/t – see January 23, 2018 news release), intersected 213.4m of 2.39 g Au/t, including two higher-grade zones of 41.2m of 5.79 g Au/t and 10.7m of 7.75 g Au/t.  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 20m.  The intercept is open at depth, where the hole bottomed in 1.89 g Au/t at 243.9m.
  • DR18-44, an RC step-out hole approximately 30m east of DS17-35 (8m of 2.96 g Au/t, including 93.0m of 5.06 g Au/t – see January 23, 2018 news release), intersected multiple zones of oxide mineralization including: 62.5m of 1.22 g Au/t; and 137.2m of 2.72 g Au/t, including 15.2m of 7.84 g Au/t and 30.5m of 4.68 g Au/t.  These intercepts are higher-grade and thicker than predicted by the resource model.  Mineralization extends approximately 30m above the current resource model.  The intercept is open at depth, where the hole bottomed in 2.01 g Au/t at 259.1m.
  • DR18-45, an RC step-out hole approximately 60m south of DR18-43 and approximately 35m east of DS17-30 (164.6m of 2.26 g Au/t, including 8m of 4.12 g Au/t and 36.6m of 3.51 g Au/t – see December 7, 2017 news release), intersected 132.6m of 1.09 g Au/t, including two higher-grade zones of 12.2m of 2.30 g Au/t and 12.2m of 3.56 g Au/t.  This intercept confirms the block model, but more importantly, extends mineralization approximately 30m below the resource model.  This intercept also remains open at depth where the hole ended in 6.37 g Au/t at 225.6m.
  • DR18-37, the northern-most step-out drill hole at Dark Star, intersected two near-surface zones of oxide mineralization including 30.5m of 0.34 g Au/t and 62.5m of 0.35 g Au/t.  These intercepts are higher-grade and thicker than predicted by the resource model, and the mineralization remains open to the north for additional drill testing.
  • Currently in the northern portion of Dark Star, 12 drill holes end in gold mineralization below the current resource model. Collectively, these results provide an opportunity to expand the resource in the hanging wall and footwall of the Ridgeline fault, and at depth.  The expansion of this zone will be a focus of upcoming drilling.

Gold intervals reported in this table were calculated using a 0.14 g Au/t cutoff.  Weighted averaging has been used to calculate all reported intervals.  True widths are estimated at 70-90% of drilled thicknesses.

 

 

This year’s US$25.8 million program includes an estimated 74,800m of RC and core drilling in 381 holes (see February 26, 2018 news release).  Of this amount, Dark Star and Pinion infill drilling is expected to account for approximately 40,800m in 296 holes while exploration should add another 34,000m of drilling in 85 holes. 

 

 

Steven Koehler, Gold Standard’s Manager of Projects commented: “Infill drilling at Dark Star continues to deliver significant value through the confirmation and expansion of +1 g Au/t, oxidized, vertically-extensive gold mineralization.  These deep oxidation plumes are a unique, favorable, repetitive pattern associated with robust gold systems on the Carlin and Cortez Trends.  Infill results continue to confirm or exceed our model expectations.  To date, drilling has not yet established a bottom to higher-grade gold zones located proximal to the Ridgeline fault where the gold system remains open to the north, west and at depth.   This openness represents exciting growth potential and these new opportunities will be a focus of drilling later this summer.”  

 

 

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 tenth sample.  The samples were delivered to Bureau Veritas Mineral Laboratories preparation facility in Elko, NV where they were crushed and pulverized.  Resulting sample pulps were shipped to Bureau Veritas certified laboratory in Sparks, NV or Vancouver, BC.  Pulps were digested and analyzed for gold using fire assay fusion and an atomic absorption spectroscopy (AAS) finish on a 30-gram split.  Over limit 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 insure 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, NV.  Final drill collar locations are surveyed by differential GPS by Apex Surveying, LLC of Spring Creek, Nevada.
