Yukon-Nevada Gold Corp. Announces 22.87 m grading 8.37 g/t Au from West Mahala, Jerritt Canyon, Nevada

VANCOUVER, Jan. 11, 2012 /CNW/ - Yukon-Nevada Gold Corp. (TSX: YNG) (Frankfurt Xetra Exchange: NG6) is pleased to announce results from its 2011 Surface drilling program at the Mahala Project which is located in its wholly-owned Jerritt Canyon gold operation in Nevada, USA.  Jerritt Canyon is operated by Queenstake Resources USA Ltd., ("Queenstake") a wholly owned subsidiary of Yukon-Nevada Gold Corp. ("YNG" or the "Company").

HIGHLIGHTS

  • MAH-457 intersected, in the West Mahala Zone, 64.05 meters at 6.38 g/t gold, including 24.4 meters at 3.43 g/t gold, and 22.87 meters at 8.37 g/t gold, and 13.42 meters at 12.28 g/t gold;
  • EM-121 intersected, in the East Mahala Zone, 15.25 meters at 4.77 g/t gold, including 3.05m at 8.88 g/t gold, and 4.88 meters 8.64 g/t gold; and
  • MAH-454 intersected, in the Mahala Zone, 32.02 meters at 4.63 g/t gold, including 15.24 meters at 6.24 g/t gold, and 3.05 meters at 8.37 g/t gold.

The company initiated a 130,000 foot surface drilling program at Jerritt Canyon on July 17, 2011 that tests multiple projects throughout the Company's 119 square mile land position.  The program was designed to either explore for and/or to convert resources to reserves that are amenable to either open pit or underground mining methods.

This press release updates the 2011 surface drill hole results in the Mahala Project that targeted converting and expanding resources proximal to the current underground operations at the Smith and SSX-Steer underground mines in the following three areas:

  • East Mahala (Smith Mine:  Zones 1, 3, and 4: including Zone 9 which is East Dash);
  • Mahala (Smith Mine:  Zone 8); and
  • West Mahala (located east of the SSX-Steer Mine).

The entire Mahala drilling program includes 71,211 ft. (21,711m) of drilling in 54 drill holes as shown in Table 1.  All fifty-four of these drill holes were conducted using reverse circulation (RC) with 16 of them finished, or planned to be finished, with diamond drilling.  The total RC footage is 61,760 ft. (18,829m) whereas the total diamond drilling footage (completed and not completed) is 9,451 ft. (2,882m).  Eighteen of these drill holes were targeted for exploration in the East Mahala and Mahala areas whereas the other 36 drill holes were for resource conversion.

Todd Johnson, Vice President of Exploration for Yukon-Nevada Gold Corp. states, "The initial assay results from the 2011 Mahala surface drilling program have come in according to our expectations based on a lot of hard work and good planning and the entire Jerritt Geology group deserves credit for a job well done.  The additional mineralization encountered in the recent drilling at Mahala and West Mahala is exciting to see."

East Mahala

Drilling at East Mahala consists of 18 drill holes totaling 22,733 ft. (6,931 m):  14 for exploration and 4 for resource conversion.  Six of these drill holes include 800-foot deep precollars.  Assay results have been received for 10 drill holes to date with significant assay results listed in Table 2.  As of year-end 2011 core tails have been completed on two of the precollars with total core drill footage totaling 868 ft. (264m).  Four core tails remain to be completed with drill footage totaling 2,295 ft. (700m); these drill holes are scheduled to be drilled by the end of January 2012.  All drilling in this area is within 1,000 ft. (305m) of the existing Smith Mine underground infrastructure.

(2) No Significant Assays: SH-1203, SH-1207, SH-1208, SH-1211, EM-123, EM-124; and EM-130;
(3) Assays Pending:  SH-1204, SH-1205, SH-1209, EM-122, EM-125; EM-127, EM-128, and EM-129

Zone 1 drilling consists of 2 exploration drill holes (EM-129 & EM-130) that were targeted along the southeasterly extension of the zone.  Assay results have been received for drill hole EM-130 and are pending for EM-129.  Mineralization in Zone 1 is interpreted to be associated with a sympathetic structure parallel to and north of the northwesterly-trending Coulee Dike structural mineralized zone which is host to significant past production (Zone 2) from the Smith Mine.  Drill hole EM-130 reported no significant mineralization.

Zone 3 drilling consists of 4 drill holes:  SH-1211 and EM-123 are exploration holes whereas  EM-121 and EM-122 are resource conversion holes.  Assays have been received for 3 of the drill holes.  Significant assays from this zone include drill hole EM-121 which contains 50.0 ft. (15.25m) grading 0.139 opt (4.77 g/t) from 955-1005 ft. (291.27-306.52m).  Drill holes EM-123 and SH-1211 reported no significant mineralization.  Mineralization in this zone is interpreted to be a sympathetic structure parallel to and north of the Mahala Dike structural zone.  This northwesterly-trending structural zone (Mahala Dike) is host to significant past production (Zone 4) from the Smith Mine.  The resource conversion drill holes were designed to in-fill potential economic mineralization that was intersected in 2010 underground drill holes SMI-LX-750 through SMI-LX-752 previously reported upon in Company news releases dated September 7, 2010 and January 24, 2011.

Zone 4 drilling consists of 5 exploration drill holes (EM-124 thru EM-128) along the southeasterly extension of the Mahala Dike structural zone.  Assays have been received for 2 drill holes:  EM-124 and EM-126.  Significant assays from drill hole EM-126 include 10 feet (3.05m) averaging 0.160 opt Au from 875.0 to 885.0 feet (266.87 to 269.92m), and 10.0 feet averaging 0.102 opt Au from 1000.0 to 1010.0 feet (305.0 to 308.05m).  Drill hole EM-124 reported no significant mineralization.

Zone 9 (East Dash) drilling consists of 7 drill holes (SH-1203 thru SH-1209).  Two drill holes (SH-1205 & SH-1206) are resource conversion holes in-filling historic drill data.  The remaining 5 exploration drill holes attempt to expand upon the known mineralization.  Assays have been received for 4 of the drill holes and are pending for holes SH-1204, SH-1205, and SH-1209.  Significant assays have been returned for drill hole SH-1206 that contains two intercepts:   40.0 ft. (12.0m) grading 0.103 opt (3.53 g/t) from 890-930 ft. (271.45-283.65m); and another intercept containing 45.0 ft. (13.72m) grading 0.133 opt (4.56 g/t) from 990.0-1035.0 ft. (301.95-315.67m).  Drill holes SH-1203, SH-1207, and SH-1208 reported no significant mineralization.

Mahala

Drilling at Zone 8 (Mahala) consisted of 16 drill holes totaling 20,350 ft. (6,204m):  4 for exploration and 12 for resource conversion.  Four of these drill holes include RC precollars.  Assay results have been received for 13 drill holes to date with significant assay results listed in Table 3.  As of year-end 2011, all of the core tails have been drilled with drill footage totaling 2,175 feet (663m).  Seven of the drill holes targeted mineralization associated with a northwesterly extension of the Coulee Dike structural zone.  Nine drill holes targeted mineralization associated with an interpreted structure sympathetic to, and parallel with, the Coulee structural zone.  These two structures have a spatial separation of approximately 150 ft. (46m).  For each structure the drilling in-fills on historic data for an approximate distance of 600 ft. (183m) northwest of the existing Zone 8 mineable reserves.  These reserves are currently undergoing access development by mining contractor Small Mine Development.

The success of the 2011 Mahala drill program has significant implications.  All three target areas require additional drilling to define the extent of mineralization.  Surface core tails are still currently being drilled at the site.  The potential for defining substantial additional mineralization is considered to be highly prospective in all three areas.

The potential future development of the Mahala and West Mahala resources is significant in that underground drifts and drill platforms should now be considered for development in order to enable year-round underground drilling to explore a sizeable area of this highly prospective ground.  This underground drilling would be free of the surface regulatory constraints as well as the encumbrances posed by the physical elements associated with surface drilling at a high altitude.

Geologic and grade modeling covering the mineralization drilled during the 2011 program is currently in progress.  Subsequent engineering analysis will be conducted.  The results of the new modeling will be included in an updated NI 43-101 report that is targeted for completion in April 2012.

As part of this 2011 Mahala surface drilling program, 16 of the RC holes were drilled to a depth of either 500 ft. or 800 ft. and served as "precollars" for subsequent diamond drilling (core tails).  The 16 core tails were designed into each of the respective resource conversion target areas to enhance the collection of geologic data and to provide assay data for comparative analysis with the surrounding RC sample population.  As of year-end 2011, all RC drilling has been completed and twelve core tails (totaling 7,156 ft. or 2,182m) have been drilled.  Four core tails still remain to be drilled totaling 2,295 ft. (700m) and most of the core assays are still in progress.  All of the Mahala drilling targeted mineralization that lies greater than 650 feet beneath the surface of the respective drill hole collars.

Assaying of all samples from the 2011 surface drill program reported in this news release were conducted by ALS Laboratory Group in Reno, Nevada using standard fire assay techniques.  Assay intercepts are reported as drilled.  True widths have not yet been calculated; given the geometry of the mineralization at Jerritt Canyon, the concept of true width is not always meaningful before delineation drilling has been completed.  The company's 2010 and 2011 Quality Assurance and Quality Control protocols are available at the Company's website:  http://www.yukon-nevadagold.com/i/pdf/JC_Assay_Protocols.pdf

All of the Mahala Project RC drill holes were sampled on 5-foot intervals over their entire length.  All samples from 0-500 feet in each respective drill hole have been deferred from lab submittal for assaying.  The primary reason was to try to expedite the return of assay results by reducing the quantity of samples submitted to the independent commercial laboratory by up to 50%.  Sample "turn-around" for the project-to-date has averaged 6 weeks due to the unprecedented work load experienced by commercial laboratories.  A secondary benefit to the sample deferral has been substantial cost savings for the project.  All of the deferred samples have been retained at the mine site for possible assay in the future.
