Yukon-Nevada Gold Corp has reported additional assay results from its 2010 Smith Mine underground exploration drilling at its wholly-owned gold production Jerritt Canyon property in Nevada, US.

The company said that eight drill holes numbered SMI-LX-750 thru SMI-LX-757 (totaling 8,126ft) have been completed at the Smith underground mine from 12 August to year end 2010.

However, the final assays have been received for the first seven drill holes.

This drill program is 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.

The first three drill holes of the exploration drilling plan tested the southeasterly extension of the previously productive Zone 3 structure at the Smith Mine along an approximate 600ft of linear strike distance.

These drill holes tested ground intersected by a limited quantity of historic surface reverse circulation (RC) drill hole tests that contained intercepts with lower grade Au mineralization.

Drill hole SMI-LX-751 encountered 39.0ft averaging 0.201 opt Au from 785.0ft to 824.0ft, and an additional intercept lower in the same drill hole containing 45.0ft averaging 0.160 opt Au from 901.0 to 946.0ft.

Assay results for drill hole number SMI-LX-752 included an intercept of 7.0ft averaging 0.134 opt Au from 1,187.0ft to 1,194.0ft and confirmed the continuity to the gold mineralization in this area.
