GOLD STANDARD INTERSECTS 47.3M OF 0.64G AU/T WEST OF THE MAIN DARK STAR OXIDE GOLD DEPOSIT, CARLIN TREND, NEVADA
Gold Standard Ventures Corp. has released assay results from this year's reverse circulation drill program within the Dark Star corridor (DSC) on its 100-per-cent-owned/controlled Railroad-Pinion project in Nevada's Carlin trend. Unlike the core drilling program exploring the high-grade North Dark Star discovery, the RC program is designed to expand the lower-grade Main Dark Star deposit and also look for new targets within the 6.7-kilometre-long DSC west and south of the Main Dark Star maiden resource.
Of 12 holes completed to date, six returned significant intercepts with gold values above the cut-off grade of 0.14 gram per tonne Au established by APEX Geoscience Ltd. of Edmonton, Canada, in its Main Dark Star resource estimate announced on March 3, 2015 (see news release). Results including 47.3 metres of 0.64 gram per tonne gold, 29.0 m of 0.67 g/t Au and 38.1 m of 0.56 g/t Au in two holes completed west of the Main Dark Star maiden resource are consistent with the grades found in the Main Dark Star resource estimate. These new results support the potential for further expansion of the Main Dark Star mineralization to the west. Last year's program demonstrated that RC assay results closely approximate those from core drilling,
The DSC is a north-trending horst defined by gravity, CSAMT, geologic mapping and soil sampling. The corridor has been largely untested by drilling until this phase of RC drilling totalling 5,804.8 metres. (Please visit the company's website to view plan and section maps.)
Jonathan Awde, chief executive officer and director of Gold Standard, commented: "The Main Dark Star oxide deposit is a valuable asset in its own right and we are confident that we can grow its resource with inexpensive RC drilling at the same time that we explore the higher-grade North Dark Star and North Bullion deposits. It is also important to note that we discovered North Dark Star by moving out into the corridor from the Main Dark Star resource. We are confident that the DSC has further high-grade occurrences to discover."
Key Dark Star corridor highlights
- In a new target west of the Main Dark Star maiden resource, drill holes
DS16-07, -10 and -19 intersected multiple, thick, significant zones of
mixed oxide and reduced mineralization including intercepts of 47.3 m of
0.64 g/t Au, 29.0 m of 0.67 g/t Au and 38.1 m of 0.56 g/t Au. These
intercepts are approximately 100 to 200 m west of the maiden resource and
are interpreted to be hosted in Tonka formation conglomerate and
Chainman formation sandstone, both of which are newly defined gold host
units at Main Dark Star. These results confirm the expansion potential
to the west of the maiden resource where mineralization is open in
several directions.
- Within DS16-07, orpiment and realgar are associated with a 9.1 m intercept of 1.08 g/t Au. These minerals are common in the reduced,
deeper portions of Carlin-type gold systems.
- Hole DS16-22, located approximately 130 m northeast of the Main Dark Star
maiden resource, returned narrow widths of gold mineralization in the
footwall of the Dark Star fault. Importantly, this hole confirms that
the gold system and the preferred debris flow conglomerate host section
continue to be present at this location.
- Eight RC scout holes were drilled south of the Main Dark Star deposit
along a two-kilometre strike length of the DSC. These holes represent the first
tests of new targets identified by the company's gravity, CSAMT, soil
geochemistry and geologic mapping programs. The southernmost hole, DS16-16, intersected silicified, iron-oxide-bearing debris flow conglomerate
with elevated arsenic. These geologic features are similar to those
observed at Main Dark Star and North Dark Star and represent a positive
first step in evaluating new early-stage targets within the DSC.
Dark Star Corridor 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.
Mac Jackson, Gold Standard's vice-president of exploration, stated: "We are just starting to explore the 6.7 km long Dark Star corridor. The intercepts in DS16-07 and DS16-10 continue to add to the size of the Main Dark Star gold system. Based on the increasing size of the system and our discovery experience at North Dark Star, we expect to find other blind deposits within the large volume of altered rock along the DSC."
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 Dark Star RC 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 downhole surveys that were completed on all holes by International Directional Services of Elko, Nev. Final collar locations were surveyed by differential GPS by Apex Surveying LLC of Spring Creek, Nev.

Gold Standard is focused on district-scale discoveries on its Railroad-Pinion gold project, located within the prolific Carlin trend. The 2014 Pinion and Dark Star gold deposit acquisitions offer Gold Standard a potential near-term development option and further consolidates the company's premier land package on the Carlin trend. The Pinion deposit now has a National Instrument 43-101-compliant resource estimate consisting of an indicated mineral resource of 31.61 million tonnes grading 0.62 gram per tonne gold, totalling 630,300 ounces of gold, and an inferred resource of 61.08 million tonnes grading 0.55 g/t Au, totalling 1,081,300 ounces of gold, using a cut-off grade of 0.14 g/t Au. The Dark Star deposit, 2.1 kilometres to the east of Pinion, has an NI 43-101-compliant resource estimate consisting of an inferred resource of 23.11 million tonnes grading 0.51 g/t Au, totalling 375,000 ounces of gold, using a cut-off grade of 0.14 g/t Au (announced March 3, 2015).
