Corvus Gold Increases Leach Gold Recovery for Savage Valley Zone of North Area Deposit, North Bullfrog Project, Nevada

February 6, 2013


VANCOUVER, Feb. 6, 2013 /PRNewswire/ – Corvus Gold Inc. (“Corvus” or the
“Company”) – (TSX: KOR, OTCQX: CORVF) announces the final results of a
series of column leach tests on large diameter core sample composites
from the Savage Valley area (Figure 1) of the North Area Deposit at the
North Bullfrog Project, Nevada.  The final results averaged 82% gold recovery at a crush size of nominally 80% passing 19mm (-3/4 inch), which is 4%
greater than the 78% gold recovery assumed in the December 6, 2012
Preliminary Economic Assessment.  The final recovery data (Table 1)
shows the high gold leachability of the Savage Valley oxide material
even at grades as low as 0.11 g/t.

These new results, along with recent column leach results from the
Mayflower Deposit (NR13-02, January 17, 2013) which indicated an
average gold recovery of 88%, suggest potential for improved overall
recovery at both the Company’s Mayflower and North Area Deposit which
could positively impact project economics.

Carl Brechtel, COO of Corvus, stated: “The ongoing North Bullfrog
Project gold recovery results continue to be very encouraging and offer
significant upside for this attractive new Nevada mining project. 
These results will be integrated with further column tests at larger
crush size to help optimize cost versus recovery.”

About the North Bullfrog Project, Nevada

Corvus controls 100% of its North Bullfrog Project, which covers
approximately 68 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 private mineral leases
of 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 project currently includes numerous prospective gold targets, with
four (Mayflower, Sierra Blanca, Jolly Jane and Connection) containing
an estimated Oxidized Indicated Resource of 27 Mt at an average grade
of 0.28 g/t gold for 246,810 ounces of gold and an Oxidized Inferred
Resource of 234.5 Mt at 0.18 g/t gold for 1,387,870 ounces of gold
(both at a 0.1 g/t gold cutoff), with appreciable silver credits. 
Unoxidized Inferred mineral resources are 221.6 Mt at 0.19 g/t for
1,361,000 ounces of gold (at a 0.1 g/t gold cutoff).

Mineralization occurs in two primary forms: (1) broad stratabound
bulk-tonnage gold zones such as the Sierra Blanca and Jolly Jane
systems; and (2) 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

rate for the deposit as a whole and to improve project economics, the
potential for the Company to secure or receive any royalties in the
future, business and financing plans and business trends, are
forward-looking statements.  Although the Company believes that such
statements are reasonable, it can give no assurance that such
expectations will prove to be correct.  Forward-looking statements are
typically identified by words such as: believe, expect, anticipate,
intend, estimate, postulate and similar expressions, or are those,
which, by their nature, refer to future events.  The Company cautions
investors that any forward-looking statements by the Company are not
guarantees of future results or performance, and that actual results
may differ materially from those in forward looking statements as a
result of various factors, including, but not limited to, variations in
the nature, quality and quantity of any mineral deposits that may be
variations in the market price of any mineral products the Company may
produce or plan to produce, the Company’s inability to obtain any
necessary permits, consents or authorizations required for its
activities, the Company’s inability to produce minerals from its
properties successfully or profitably, to continue its projected
growth, to raise the necessary capital or to be fully able to implement
its business strategies, and other risks and uncertainties disclosed in
the Company’s latest interim Management Discussion and Analysis and
filed with certain securities commissions in Canada.  All of the
Company’s Canadian public disclosure filings may be accessed via www.sedar.com
and readers are urged to review these materials, including the technical
reports filed with respect to the Company’s mineral properties.

Cautionary Note Regarding References to Resources and Reserves

National Instrument 43 101 – Standards of Disclosure for Mineral
Projects (“NI 43-101″) is a rule developed by the Canadian Securities
Administrators which establishes standards for all public disclosure an
issuer makes of scientific and technical information concerning mineral
projects.  Unless otherwise indicated, all resource estimates contained
in or incorporated by reference in this press release have been
prepared in accordance with NI 43-101 and the guidelines set out in the
Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”)
Standards on Mineral Resource and Mineral Reserves, adopted by the CIM
Council on November 14, 2004 (the “CIM Standards”) as they may be
amended from time to time by the CIM.

United States shareholders are cautioned that the requirements and
terminology of NI 43-101 and the CIM Standards differ significantly
from the requirements and terminology of the SEC set forth in the SEC’s
Industry Guide 7 (“SEC Industry Guide 7″).  Accordingly, the Company’s
disclosures regarding mineralization may not be comparable to similar
information disclosed by companies subject to SEC Industry Guide 7. 
Without limiting the foregoing, while the terms “mineral resources”,
“inferred mineral resources”, “indicated mineral resources” and
“measured mineral resources” are recognized and required by NI 43-101
and the CIM Standards, they are not recognized by the SEC and are not
permitted to be used in documents filed with the SEC by companies
subject to SEC Industry Guide 7.  Mineral resources which are not
mineral reserves do not have demonstrated economic viability, and US
investors are cautioned not to assume that all or any part of a mineral
resource will ever be converted into reserves.  Further, inferred
resources have a great amount of uncertainty as to their existence and
as to whether they can be mined legally or economically.  It cannot be
assumed that all or any part of the inferred resources will ever be
upgraded to a higher resource category.  Under Canadian rules,
estimates of inferred mineral resources may not form the basis of a
feasibility study or prefeasibility study, except in rare cases.  The
SEC normally only permits issuers to report mineralization that does
not constitute SEC Industry Guide 7 compliant “reserves” as in-place
tonnage and grade without reference to unit amounts.  The term
“contained ounces” is not permitted under the rules of SEC Industry
Guide 7.  In addition, the NI 43-101 and CIM Standards definition of a
“reserve” differs from the definition in SEC Industry Guide 7.  In SEC
Industry Guide 7, a mineral reserve is defined as a part of a mineral
deposit which could be economically and legally extracted or produced
at the time the mineral reserve determination is made, and a “final” or
“bankable” feasibility study is required to report reserves, the
three-year historical price is used in any reserve or cash flow
analysis of designated reserves and the primary environmental analysis
or report must be filed with the appropriate governmental authority.

Caution Regarding Adjacent or Similar Mineral Properties

This news release contains information with respect to adjacent or
similar mineral properties in respect of which the Company has no
interest or rights to explore or mine.  The Company advises US
investors that the mining guidelines of the US Securities and Exchange
Commission (the “SEC”) set forth in the SEC’s Industry Guide 7 (“SEC
Industry Guide 7″) strictly prohibit information of this type in
documents filed with the SEC.  Readers are cautioned that the Company
has no interest in or right to acquire any interest in any such
properties, and that mineral deposits on adjacent or similar properties
are not indicative of mineral deposits on the Company’s properties.

This press release is not, and is not to be construed in any way as, an
offer to buy or sell securities in the United States.
