Assay results have been received as of January 25, 2011 for the final drill hole number SMI-LX-757 that was completed as part of the 2010 Smith Mine underground drill hole program (see drill hole location plan maps which can be found on our website here: https://www.yukon-nevadagold.com/i/pdf/NR_03_2011_UG_DDH.pdf). This drill program is continuing in 2011 and testing favorable ore controlling structures proximal to the existing underground workings and is also intended to expand and convert existing resources outlined in the most recent NI 43-101 report published in 2008.
Drill hole SMI-LX-757 is a resource conversion drill hole that was drilled from an underground drill station in Zone 2 of the mine and is located east of drill hole SMI-LX-755 and west of and below hole SMI-LX-756. Assays for these other two drill holes have been previously reported in the press release dated January 24, 2011. Four separate zones from drill hole SMI-LX-757 contain significant assay results (see Table 1):

These results confirm the continuity of the gold mineralization in the area north of existing Zone 2 mine workings and west-southwest of existing Zone 5 workings.
SMI-LX-757 was drilled in the hanging wall parallel to the strike of the northwest-trending Coulee fault zone. The first mineralized intercept was characterized by intense silicification and quartz vein breccia in the Ordovician-Silurian Hanson Creek Formation (unit 1) adjacent to decalcified, carbonaceous, and sheared Hanson Creek Formation (unit 3). The second mineralized zone consists of decalcified and locally silicified rock from the Hanson Creek Formation (unit 3) with trace realgar. The third relatively narrow intercept is not strongly altered but contains moderate realgar in slightly sheared rock from the Hanson Creek Formation (unit 3). The final mineralized interval is characterized by carbonaceous, decalcified, and argillized rock from the Hanson Creek Formation (unit 3) with some pyrite lenses, disseminated pyrite, and/or locally abundant realgar.
Drill holes SMI-LX-758 and SMI-LX-759 were drilled in January 2011 above and below SMI-LX-757 to test the vertical extent of the mineralization encountered in drill hole SMI-LX-757. Results of these two drill holes are pending. Additional drilling is planned in 2011 from the same Zone 2 drill station to test the lateral extents of the mineralization.
Assays from the underground diamond drill hole reported in this news release were performed by ALS Laboratory Group in Reno, Nevada, using standard fire assay techniques. Intercepts are reported as drilled. True widths have not yet been calculated; given the geometry of mineralization at Jerritt Canyon, the concept of true width is not always meaningful before delineation drilling has been completed.
