Gold Standard Reports Drilling Continues to Expand North Bullion
Gold Deposit in Carlin Trend, Nevada
Preliminary Metallurgical Results Show Excellent Gold Recoveries
for North Bullion Deposit Using Standard Carlin Processing
Technologies
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jan 22, 2014) - Gold
Standard Ventures Corp. (TSX-VENTURE:GSV)(NYSEMKT:GSV)(NYSE
Amex:GSV) ("Gold Standard" or the "Company")
(www.goldstandardv.com) today released results from RR13-14, the
most recent hole drilled (in late 2013) into the North Bullion
deposit. Results include an interval of 30.6 meters of 1.23 gAu/T
starting at 294.7meters and 39.9 meters of 0.65 gAu/T starting at
337.5 meters. These intervals effectively offset and extend the
critical lower breccia zone another 65 meters (200 ft) to the west
of RR13-11. The North Bullion deposit remains open to further
expansion to the west and to the north. Another step-out, RR13-15,
is set to be drilled about 65 meters further to the west (see map
below).
Gold Standard also reported that Newmont USA Limited, a
subsidiary of Newmont Mining Corporation (NYSE:NEM) ("Newmont") has
provided the Company with the results of metallurgical tests of
drill core from the North Bullion deposit conducted by Newmont. The
tests were designed to determine if North Bullion deposit
mineralization is amenable to the established recovery technologies
commonly used for Carlin-type ores. Three samples were taken from
composited quarter-cut North Bullion drill core; all three samples
were considered to be refractory material. The samples assayed
2.30gAu/T (0.067 ozAu/st), 11.7gAu/T (0.340 ozAu/st) and 8.06gAu/T
(0.235 ozAu/st). Gold recoveries were 83.1%, 90.0% and 78.8%
respectively, indicating that North Bullion mineralization is
likely to be conducive to roaster processing.
Highlights:
- Drill holes RR13-08, RR13-11, together with the most recent
hole RR13-14, appear to indicate a west-trending "bulge" or
"extension" in the North Bullion deposit. This change in
mineralization pattern could represent an association with an
important west-northwest-trending feeder structure.
- The North Bullion gold mineralization appears to be conducive
to roaster processing.
Metallurgical test details:
Three samples of material from the Railroad property were
provided to Newmont. Each sample was taken from drill core and was
expected to be refractory. A scope of work was generated to conduct
head assays (duplicate fire assays, AuCN assays, and preg-rob
assays), carbon and sulfur assays with a LECO furnace and a
multi-element ICP-MS assay. The samples were carbonaceous and
sulfidic refractory with very different gold grades, arsenic grades
and sulfide sulfur contents.All three samples responded reasonably
well to bench top roast tests with recoveries between 78% and
90%.
Sample #1 represents a 95 foot lower breccia interval from 1200
to 1295 feet in hole RR11-18.
Sample #2 represents a 45 foot upper breccia interval from 960
to 1005 feet in hole RR12-01.
Sample #3 represents a 20 foot lower breccia interval from 1160
to 1180 feet in hole RR13-08.

Roaster recoveries varied between 78.8% and 90% as shown in
Table 2. The cause of the recovery variances was not determined.
Sulfide sulfur burns were between 94% and 96% and organic carbon
burns were between 78% and 93%. The results suggest that the roast
was complete. The calcines had calculated preg-rob values between 0
and 0.007 opt with AA/FA ratios between 77% and 84% further
supporting the conclusion that all the organic carbon was
burned.

Dave Mathewson, Gold Standard's Vice President of Exploration,
stated: "We are pleased with the metallurgical results for the
North Bullion gold deposit. The results indicate that the
refractory material is suitable to either roaster or autoclave
beneficiation and these facilities exist within reasonable trucking
distance of our Railroad project. We are also excited by the
continuing lateral expansion of the North bullion deposit. Each
successive hole is adding significant mineralized tonnage which we
expect to be reflected in the resource estimate scheduled for later
this year."
North Bullion Drilling update:
Gold Standard is also pleased to report the final assay results
for the late 2013 North Bullion drilling campaign. Hole RR13-14 is
a -85° east directed hole designed to provide a west offset of the
lower breccia mineralization encountered in holes RR13-08 and 11.
The hole encountered a total of about 70 meters of gold
mineralization within the lower breccia (see table below). Of
particular importance in this hole is the style and degree of
silica, barite, and dolomite alteration at this distance from the
Bullion Fault Corridor. The strength and amount of this alteration
strongly suggest proximity to a system feeder structure. This hole
steps further away from the Bullion Fault Corridor structure zone
therefore another feeder structure at different location and
orientation appears to be in play.

*note: the gold intervals reported in the above table are based
on a 0.250 g Au/t (0.007 oz Au/st) cutoff. Weighted averaging has
been used to calculate all reported intervals. The reported gold
intervals may, or may not represent true thicknesses and, or
widths. In general, the gold distribution within these large,
complex breccia bodies tends to be irregular and will require
additional drilling to establish true widths.
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. Core was cut at the company's facility in Elko and one
half was sent to the lab for analysis and the other half retained
in the original core box. A blank, quarter core duplicate or
certified reference material was inserted approximately every tenth
sample. The samples are delivered to ALS Minerals preparation
facility in Elko. The samples are crushed and pulverized and sample
pulps are shipped to ALS Minerals certified laboratory in
Vancouver. 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.
