DRILLING CONTINUES

Dumont Nickel has mobilized a second drill at the Clifton Mining property.  This is a core drill, and it has drilled eight holes to date.  Three were on sites of previous RC (reverse circulation) drill holes to verify the accuracy of the RC holes.  The other five were new holes.  The continued exploration plan is to have the core rig complete an additional 10-20 holes in the Midzone and Rainbow Hill areas.

The RC rig completed seven additional holes at the Midzone and Rainbow Hill areas, before being moved to Cane Springs.  The rest of the drilling in these areas will be completed by the core drill, as the drilling here is beyond the capability of the RC drill rig.  Each of the RC holes intersected stockworks, the geological formation that hosts the gold at the southern end of the Kiewit zone.  This is encouraging, as it suggests that the same mineralized structure may extend over the entire north-south length of the Kiewit Zone, but stills needs to be determined by the ongoing exploration work.

The RC rig has been moved to Cane Springs, where it is part of the way through a 23 hole closely-spaced drill program on the flanks of that mine.

In addition, a 7.5 square kilometer geophysical survey on the Kiewit zone has just begun.  The object of the survey is to delineate extensions of the zone and possible feeder veins beneath the sedimentary cap in the western portions of the zone.

Dumont will also be resuming surface work over the 10 km long belt of jasperoid and other breccias crossing the full length of our property.  Jasperoid breccias are the most visible indicator of gold mineralization throughout the Carlin Trend.
