Corvus Gold Expands North Bullfrog’s Sierra Blanca Deposit to the
West and North, Intersecting 16.8m @ 1.37 g/t Gold & 24.4m @ 1.21
g/t Gold and Stakes Land Package Adjacent to New Kinross Gold
Claims
Vancouver, B.C… Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX:
CORVF) announces it has received assay results from drill holes (detailed in Table 1 below)
testing new targets with several returning positive results (Figure 3) at the 100% owned Nevada,
North Bullf rog Project . The most significant results were returned from new zones west and
north of the Sierra Blanca/YellowJacket deposit.
The WSB target area (West Sierra Blanca) is a large pediment covered area over a kilometre
long and half a kilometre wide, with assays pending on 7 additional completed holes.
Mineralization in this area is dominantly oxide with the oxide -sulfide boundary variable from
100 to 200 metres in depth similar to most areas at North Bullfrog. The Company plans to
complete an additional 20 holes at the WSB target in this phase.
New Land Package
Corvus recently staked a large block of land (Gap Claims, Figure 2) on the southern extension of
the new Kinross Gold Corporation land package in the southwestern part of the District (Figure 1
& 2). This area contains a large regional structural zone called the Ransome Fault that hosts the
historic, high-grade, original Bullfrog gold deposit. Corvus believes t he target environment is
analogous to the Mother Lode setting with mineralization focused at the volcanic -basement
contact which is largely untested in this area.
The new claims are also adjacent to the west side of the large AngloGold A shanti Limited,
Rhyolite project and contains the western extension of their large, high level alteration system
that Corvus believes has similarities to the Silicon area to the east side of the District . Corvus is
currently conducting an in -depth surface exploration program on the target in preparation for
scout drilling later this fall.
Corvus also tested other early stage targets at North Bullfrog with three returning positive results
that warrant follow -up (Tab le 1). The first two holes ever drilled in the Cat Hill West target
returned a shallow intercept (15.2m @ 0.58 g/t gold) with abundant surrounding low -grade. In
addition, results from testing the northern extension of the YellowJacket vein deposit returned
encouraging results with 24.4 metres of 1.21 g/t gold surrounded by zones of low-grade.

Jeff Pontius, President and CEO of Corvus, said, “The initial results from our new discovery
program at North Bullfrog have been encouraging with significant mineralization in a number of
areas and several broad zones of low -grade gold . We believe th at the newly identified
mineralization at WSB and Cat Hill could hol d the key for expansion of YellowJacket type
mineralization in the North Bullfrog area. These well-mineralized, structural zones have never
been explored due to the thin post -mineral cover and offer an opportunity to discover additional
YellowJacket type systems within North Bullfrog . Additionally, we believe the staking of our
new Ransome target is exciting as it is strategically placed between both the Kinross Gold and
AngloGold Ashanti properties with potential to be an attractive high-grade target.”

West Sierra Blanca
The initial holes in the WSB target are testing structural zones on the west side of the main
deposit that are currently in or marginal to areas of untested waste material. The positive results
from hole NB19-456 (16.8m @ 1.37 g/t Au) is from a north trending structural zone. This zone
is characterized by disseminated and fine stockwork quartz and intrusive dikes similar in texture
to those at YellowJacket and Mother Lode a nd look s to be extending to depth from an oxide
horizon into a deeper sulfide system. Corvus believes the alteration and large areas of
surrounding low -grade gold are similar to the h igh-grade system at YellowJacket that lies a
kilometre to the east. The current target area is about one kilometre long, a half a kilometre wide
and covered with a thin veneer of pediment (<10m). Ongoing drilling in this target area has been
able to define and extend several of these , dike filled, structural zones as we continue with an
aggressive follow-up program.
North YellowJacket
Hole NB19 -455 tested the potential for expanding the YellowJacket vein system to the north.
The positive results (24.4m @ 1.21 g/t Au) i ndicate the system is more north -south than
previously thought and a follow -up program is planned to continue working on defining t he full
extent of the system. I n addition, Corvus has designed a deep test of the Y ellowJacket gold

system to assess repeated vein zones at depth which are common in this type of epithermal
systems.
West Cat Hill
The West Cat Hill target is a large untested alteration system to the west of the District scale
Road Fault. Hole NB19 -446 intersected a broad stockwork quartz zone that was well
mineralized (15.2m @ 0.58 g/t) and is typical of the upper parts of YellowJacket or Bullfrog type
high-grade vein systems. The alteration system in this area is large and the mineralization in
hole NB19-446 will be followed up with additional drilling at depth and along strike.
South Jolly Jane
Mineral resource extension drill testing of the Jolly Jane deposit to the south produced
encouraging results with 36.6m of 0.34 g/t gold in hole NB19-448. This mineralization indicated
the favorable Jolly Jane mineralized horizon extends to the south, o ffering future mineral
resource expansion potential. In addition, hole NB19 -449 ended in lower plate carbonates that
were altered to jasperoid and had 9.2m of 0.19 g/t gold w hich Corvus believes could be a distal
indicator of a sediment hosted system in the lower pl ate carbonates that underlie most of the
North Bullfrog gold systems ( similar to our Mother Lode deposit). Follow -up exploration will
be planned for this area in the future.
Other Results
Results from the Jasperoid and West Air Track target s returned no significant results and no
further work is planned on these areas during this phase of North Bullfrog exploration.
