CORVUS GOLD CONTINUES EXPANDING YELLOWJACKET HIGH-GRADE GOLD & SILVER ZONE, WITH DISCOVERY OF NEW VEIN SYSTEMS, NORTH BULLFROG PROJECT, NEVADA
Corvus Gold Inc. has released assay results from two
core holes and three reverse circulation (RC) holes in the Yellowjacket
zone at the North Bullfrog project, Nevada. The drill results from the
Yellowjacket zone have identified new high-grade gold vein systems and
expand near-surface mineralization along trend to the North increasing
the projects starter pit potential.
Complete assay results from core drill hole NB-13-347 (partially
announced on Aug. 6, 2013) was 84.8 metres of 1.6 grams per tonne (g/t) gold and 10.1 g/t silver including the previously reported intercept of 7.2 g/t gold and 21.0 g/t silver over 13.8 metres. Drill hole NB-13-347 represents a 260-metre step-out to the
north of the original discovery hole NB-12-138. Significantly, hole
NB-13-347 intersected a new high-grade vein system where drilling to
date has now outlined four distinct vein systems within the overall
100-to-150-metre-wide north-northwest-trending Yellowjacket zone.
In addition, core hole NB-13-348, drilled on the same section as
NB-13-347, returned an intercept of 61.3 metres of 0.7 g/t gold. Core holes NB-13-353 and NB-13-354, located 360 metres
north of the discovery hole NB-12-138, both encountered broad zones of
veining with similar characteristics as hole NB-13-347 (assays are
pending).
RC hole NB-13-230, which represents a 500-metre step-out to the north
from the 2012 discovery hole returned 172.2 metres of 0.45 g/t gold including 25.9 m of 1.2 g/t gold. Significantly some intervals returned high silver-to-gold ratios
indicating that the hole crossed Yellowjacket-style vein mineralization. The gold mineralization at the bottom of the hole
and represents a significant increase in the grade of the alteration-style mineralization and has been followed up with core hole NB-13-350.
Assay results from NB-13-347 and NB-13-230 along with core from holes
NB-13-353 and 354 appear to have intersected an entirely new vein
system of gold mineralization. The new vein system appears to be
trending northwesterly from the Yellowjacket zone toward North Sierra
Blanca and could be indicating a broadening of the high-grade zone to
the north. This new high-grade gold system remains open to
the north, south and at depth and lies west of the other three distinct
vein systems.
Drill road construction and RC grid drilling has recently intersected
other vein systems to the west of Yellowjacket opening up more
potential for expanding the high-grade feeder system under the existing
Sierra Blanca deposit.
RC holes NB-13-225 and 229 are vertical holes that were drilled in the
horst block between an east-dipping fault and a west-dipping vein
system. Neither hole encountered vein mineralization but both holes
encountered very broad zones of the disseminated, low-grade
mineralization that surrounds the high-grade vein systems.
Jeff Pontius, chief executive officer, stated: "The continued
encouraging results from the Yellowjacket zone are now defining a large
and expanding zone of shallow, much higher-grade, open-pit, heap leach
material for the initial phase of mining at North Bullfrog. In
addition the discovery of additional high-grade veins over a broad area
highlights the potential for the high-grade system to grow in scale to
that of the plus-two-million-ounce Bullfrog mine located to the south of the
project. These ongoing results are outlining what could be a major new
Nevada high-grade gold discovery that could greatly enhance Corvus
shareholder value."

About the North Bullfrog project, Nevada
Corvus controls 100 per cent of its North Bullfrog project, which covers
approximately 70 square kilometres in southern Nevada just north of the historic
Bullfrog gold mine formerly operated by Barrick Gold Corp. The
property package is made up of a number of leased patented federal
mining claims and 758 federal unpatented mining claims. The project
has excellent infrastructure, being adjacent to a major highway and
power corridor. The company's independent consultants completed a
robust positive preliminary economic assessment on the existing
resource in June, 2013.
The project currently includes numerous prospective gold targets with
four (Mayflower, Sierra Blanca, Jolly Jane and Connection) containing
an estimated oxidized indicated resource of 36.7 million tonnes at an average grade
of 0.26 g/t gold for 308,000 ounces of gold and an oxidized inferred
resource of 220.4 million tonnes at 0.18 g/t gold for 1,289,000 ounces of gold
(both at a 0.1 g/t gold cut-off), with appreciable silver credits.
Unoxidized inferred mineral resources are 221.6 million tonnes at 0.19 g/t for
1,361,000 ounces of gold (at a 0.1 g/t gold cut-off).
Mineralization occurs in two primary forms: broad strata-bound
bulk-tonnage gold zones such as the Sierra Blanca and Jolly Jane
systems; and moderately thick zones of high-grade gold and silver
mineralization hosted by structural zones with breccias and
quartz-sulphide vein stockworks such as the Mayflower and Yellowjacket
targets. The company is actively pursuing both types of
mineralization.

On-site personnel at the project log and track all samples prior to
sealing and shipping. Quality control is monitored by the insertion of
blind certified standard reference materials and blanks into each
sample shipment. All resource sample shipments are sealed and shipped
to ALS Chemex in Reno, Nev., for preparation and then on to ALS
Chemex in Reno, Nev., or Vancouver, B.C., for assaying. ALS Chemex's
quality system complies with the requirements for ISO 9001:2000 and ISO 17025:1999. Analytical accuracy and
precision are monitored by the analysis of reagent blanks, reference
material and replicate samples. Finally, representative blind duplicate
samples are forwarded to ALS Chemex and an ISO-compliant third party
laboratory for additional quality control. McClelland Laboratories Inc.
prepared composites from duplicated RC sample splits collected during
drilling. Bulk samples were sealed on-site and delivered to McClelland
Laboratories Inc. by ALS Chemex or Corvus personnel. All metallurgical
testing reported here was conducted or managed by McClelland
Laboratories Inc.
