Met Tests Confirm Potential to Leach Gold Standard's Bald Mountain
Gold-Copper Oxide Discovery on Railroad Project With Preliminary
Agitation-Leach Recoveries Averaging 82.2%
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jan 23, 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 metallurgical
tests on the Bald Mountain gold-copper oxide discovery made by Gold
Standard last fall on its 100%-owned Railroad Project in the Carlin
Trend of Nevada. The tests, performed by Inspectorate Labs of Reno,
Nevada, reported an average 82.2% recovery of gold after one hour
of cyanide agitation leach.
As reported on October 2, 2013, the first hole drilled into the
Bald Mountain target, vertical core hole RRB13-1, intersected 56.1
meters of 1.47 g Au/T, including an internal interval of 7.3 meters
of 5.66 g Au/T. Importantly, the gold intercept was hosted entirely
in oxidized hornfels breccia, representing the most significant
oxidized gold mineralization found to date in the northern Railroad
project area. Gold in oxidized mineralization can typically be
recovered using methods such as cyanide leaching which are less
expensive and less capital-intensive than those required to recover
gold from non-oxidized (sulphide) material.
Immediately below the gold intercept, RRB13-1 also intersected a
separate copper zone returning 23.3 meters of 0.4% copper as well
as narrower but high-grade intercepts of other base metals and
silver.
Recognizing the potential economic significance of the Bald
Mountain discovery, Gold Standard commissioned metallurgical tests
of the core. Inspectorate used the following procedure: 30 gram
samples were agitation-leached for one hour at room temperature in
60mls of 0.3% sodium cyanide solution. The solution also had a 0.3%
concentration of sodium hydroxide in order to stabilize the pH at
greater than 10. Pregnant solutions were analyzed by a
matrix-matched-calibrated AAS. Internal blanks, standards and
duplicates were also analyzed at a frequency of approximately one
of each for every 35 samples.
Fourteen of fifteen samples provided an unweighted average
recovery of 82.2%. The better recoveries were skewed toward the
higher grade samples (see table below):

Dave Mathewson, Gold Standard's Vice President of Exploration,
stated: "We are very pleased with the excellent preliminary
metallurgical results from the Bald Mountain target. Visually, we
have been seeing very deep and strong oxidation in the holes we
have been drilling in the Central Bullion area. Now that we have
confirmed that these oxide opportunities are likely to be
leachable, especially as indicated in RRB13-01, we will focus on
expanding the Bald Mountain target and identifying other oxide
opportunities in the area."
Gold Standard also herewith reports the most significant assay
from two holes, RRB13-02 & RRB13-03, completed in late 2013
within the Central Bullion area, from the Sylvania and Steve's Camp
targets, respectively. While the mineralization in these targets
remains of interest, work in the Central Bullion area will focus on
the high gold values found at Bald Mountain.

RRB 13-3.

*Note: the gold intervals reported in the above table
are based on a 0.200 g Au/t 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.
