Yukon-Nevada Gold Corp. Reports Revised Resources at Jerritt Canyon, Nevada
VANCOUVER, Jan. 6, 2012 /CNW/ - Yukon-Nevada Gold Corp.
announces a revised mineral resource estimate for its wholly-owned Jerritt Canyon operating gold mine in Elko County, Nevada, USA. Jerritt Canyon is operated by Queenstake Resources USA Ltd., a wholly owned subsidiary of Yukon-Nevada Gold Corp. ('YNG' or the 'Company').Jerritt Canyon's measured and indicated mineral resource has increased by 428.8 koz of gold, representing a 21% increase over year-end 2007 levels. The updated mineral resource estimate incorporates a new 3-D geological model which includes additional drill hole results from January 1, 2008, to January 1, 2011.
The new mineral resource now comprises a measured resource of 1.07 million ounces, an indicated resource of 1.32 million ounces, and an inferred resource of 0.75 million ounces. This new model significantly increases the potential of the property and gives the Jerritt Canyon Geology team additional areas to explore and develop. The updated mineral resources completed to date include the primary work areas: Smith, SSX-Steer, Saval, West Mahala and Starvation Canyon.
The tables below summarize the updated mineral resources and are separated by open pit and underground, and by measured, indicated and inferred categories.

Notes:
(1) The January 1, 2011 underground mineral resources (in bold) are
presented using a 0.125 opt Au cutoff grade and the Wright Window
open pit resource used a 0.042 opt Au cutoff grade; a US$1,150/oz
gold price was used for all revised resources; the January 1,
2011 underground resources were only tabulated if they were
within 750 feet of existing or designed workings and contained
more than 1000 tons; whereas the reviewed December 31, 2007
underground mineral resources from SRK (2008) used a 0.150 opt Au
cutoff grade for undeveloped resources and a 0.125 opt Au cutoff
grade for more mature underground resources;
(2) the SRK 2008 open pit resources were verified and/or modified as
part of this study and were calculated using variable cutoff
grades from 0.068 opt to 0.086 opt Au at lower gold prices ($450
to $550 per oz);
(3) The Wright Window resource was revised using the Year-End 2008
block model and the January 1, 2011 classification system;
(4) Coyote Zone 10 OP and UG, Burns Basin UG, and Murray UG resources
were revised for this study;
(5) The January 1, 2011 stockpile resource is classified as indicated
and reconciled to that published in the Year-End 2007 NI 43-101
report;
(6) Mineral resources that are not mineral reserves do not have
demonstrated economic viability;
(7) Further drilling and modeling of the Burns Basin open pit
resource have resulted in a reduction in the Measured and
Indicated Resources set out in the Company's September 21, 2011
press release. As a result of the latest drilling campaign
encountering non-documented backfill, the Measured Resource
decreased from 170.2 ktons averaging 0.163 opt Au containing 27.8
koz Au to 53.2 ktons averaging 0.086 opt Au containing 4.6 koz;
and the Indicated Resource decreased from 2,062.4 ktons averaging
0.104 opt Au containing 213.5 koz Au, to 665.9 ktons averaging
0.081 opt Au containing 54.0 koz;
(8) OP = open pit; UG = underground.

Notes: Similar resource tabulation methodologies described for Table 1 above apply to the resources in Table 2.
The January 1, 2011 Resources compared to the previous December 31, 2007 Resource Statement by SRK (2008) shows the following:
-- The Measured resources have increased by 73% (on a tonnage
basis) or by 1,923.9 kt and 367.0 koz;
-- The Indicated resources have increased by 16% (on a tonnage
basis) or by 888.6 kt and 61.8 koz;
-- The Inferred resources have increased by 67% (on a tonnage
basis) or by 1,552.9 kt and 230.9 koz;
-- The indicated Jerritt stockpile resource (remote + mill) has
increased by 10.3% (on a tonnage basis) or by 83.9 kt and 17.8
koz based on additional stockpile materials being discovered
and/or mined in 2010 (including 2010 mining depletion) and due
to a lower economic cutoff grade when calculated using a Au
price of $1,150 per ounce; and
-- The measured Jerritt stockpile (remote + mill) has decreased
100% to 0 kt as a result of reclassification of the stockpile
ores as all indicated, and because of mining from 2008 to 2010.
The aforementioned Jerritt Canyon resources are slightly lower than those stated in YNG's May 3, 2011 press release and the June 28, 2011 Jerritt Canyon NI 43-101 report. The reasons for the slightly lower resource listed in this press release are: a more consistent methodology to identify potentially economic underground resources (located within 750 feet of a design or as-built underground working and greater than 1000 tons; and a more critical review of the other underground and open pit resources included in the previous SRK Consulting 2008 Technical Report that were originally not updated with new models. Some underground resources such as Winters Creek and Waterpipe II were excluded from this revised resource statement since the present authors did not verify the old models.
The 2011 Jerritt Canyon mineral resources were calculated by Karl Swanson, Mining Engineer Consultant, under the supervision of Todd Johnson, Vice President of Exploration for YNG. These individuals are Qualified Persons as defined by NI 43-101. YNG is preparing an amended NI 43-101 Technical Report which will include these new resource results that will be separated by open pit and underground mining methods; the details of this recent resource review will be included in this report. It is anticipated that this full amended NI 43-101 Technical Report will be available and released on January 6, 2012. Mr. Johnson supervised the preparation of the technical information, has reviewed and approved the contents of this new release, and is the Qualified Person for this news release.
The mineral resources have been estimated in accordance with the standards adopted by the Canadian Institute of Mining, Metallurgy and Petroleum ('CIM') Council in August 2000, as amended, and prescribed by the Canadian Securities Administrators' National Instrument 43-101 Standards of Disclosure for Mineral Projects. The resources were classified according to: geological confidence, number of drill holes, number of drill hole samples and a specific search distance.
The January 1, 2011 Reserves have remained the same as reported in the June 28, 2011 NI 43-101 Technical Report. The January 1, 2011 reserves have changed in tons and grade and classification category but contain an overall similar contained ounce total (Proven + Probable reserves = 717.0 koz) to that reported in the previous NI 43-101 Technical Report by SRK (2008). The January 1, 2011 Reserves include Proven reserves of 1,406.1 ktons averaging 0.193 opt Au containing 270.9koz, and probable reserves of 2,959.7 ktons averaging 0.151 opt Au containing 446.0 koz.

WARNING: The Company relies upon litigation protection for 'forward-looking' statements.
This news release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the United States. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the 'U.S. Securities Act') or any state securities laws and may not be offered or sold within the United States or to U.S. Persons unless registered under the U.S. Securities Act and applicable state securities laws or an exemption from such registration is available.
Cautionary Note to U.S. Investors Regarding Estimates of Measured, Indicated and Inferred Resources
This press release uses the terms 'measured,' 'indicated and 'inferred' 'resources.' We advise U.S. investors that while these terms are recognized and required by Canadian regulations, the U.S. SEC does not recognize them. 'Inferred resources' have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an 'inferred mineral resource' will ever be upgraded to a higher category. Under Canadian rules, estimates of 'inferred mineral resources' may not form the basis of a feasibility study or prefeasibility studies, or economic studies except for Preliminary Assessment as defined under NI 43-101. The SEC normally only permits issuers to report mineralization that does not constitute 'reserves' as in-place tonnage and grade without reference to unit measures. U.S. investors are cautioned not to assume that any part or all of a measured, indicated or inferred mineral inventory resource exists or is economically or legally mineable.
