Yukon-Nevada Gold Corp. reports on reserves at Jerritt Canyon, Nevada
Yukon-Nevada Gold Corp. (the “Company”) announces that proven and probable reserves at its 100% owned Jerritt Canyon operating gold mine in Elko County, Nevada, estimated as of January 1, 2011, is 717,000 ounces of gold at an average grade of 0.164 ounces of gold per ton (opt) or 5.62 grams of gold per tonne (gpt).
These reserves are within a newly estimated measured and indicated resource, of 2.54 million ounces (1.08 million ounces measured at a grade of 0.235 opt Au, and 1.46 million ounces indicated at a grade of 0.206 opt Au), which was previously announced in a press release on May 3, 2011. The attached table summarizes the reserves by area; the map showing the reserve and resource area locations can be seen on the Company’s website here: http://www.yukon-nevadagold.com/i/pdf/JCResourceMap2011.pdf
Table 1. Jerritt Canyon Reserves: January 1, 2011
- The January 1, 2011 resources were all calculated using various Au cut off grades depending on the mine area using a Au price of US$1,100 per troy oz.; and the following mining parameters: $32.00 processing cost, $81.00/ton mining cost; 89.0% Au recovery; 10% underground mining dilution at 0 opt Au grade; $6.00/ton G&A; and $4.62/ton ore haulage;
- Stockpile resources include remote and mill and were measured on January 1, 2011;
- All reserves are underground except for Wright Window which is open pit;
- Resources calculated using: additional drill holes completed in 2008-2010, and applicable mining depletions (underground asbuilts completed as of year-end 2010).
Table 1 indicates that proven reserves total 1,406.1ktons tons averaging 0.193 opt totaling 270.9koz of Au whereas probable reserves stand at 2,959.7ktons averaging 0.151 opt Au totaling 446.0koz. These new proven and probable reserves, along with the recently published resources, will be included in the final NI 43-101 technical report update which is expected to be published in late June 2011.
The individual January 1, 2011 reserves have generally increased in tonnage and recovered ounces and decreased in Au grade in comparison to the previous Year-End 2007 NI 43-101 report by SRK (2008) with the exception of Starvation Canyon. The reclassification of the majority of the measured and indicated resources at Starvation Canyon, to an inferred resource in the current work, is the primary reason for the reserve decrease at Starvation Canyon.
The January 1, 2011 reserve was calculated by Mark Odell (P.E.), a consulting Mine Engineer, and Karl Swanson (MAusIMM, SME), Mining Engineer Consultant, under the supervision of Todd Johnson (P.E.), Vice President of Exploration for YNG. These individuals are qualified persons as defined by NI 43-101.
The mineral reserves 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.
Mining at the Jerritt Canyon property is currently active at the Smith Underground mine which is producing approximately 1,000 ore tons per day using Small Mine Development, LLC as the mining contractor. Queenstake Resources USA, Inc., a 100% subsidiary of YNG, is planning to recommence mining at the SSX-Steer underground mine in the third quarter of 2011.
