Rossing South Exploration Programme

With additional percussion drilling equipment now on site, the RC rig previously at Garnet Valley is now free to resume the initial drilling campaign at Rossing South. This programme of work has already successfully located uranium bearing leucogranites concealed by transported cover in an area interpreted to contain similar lithologies to those hosting the nearby world class Rossing deposit. Drilling will recommence at Rossing South to follow-up on the 160+m wide uranium anomalous zone previously encountered. In addition, a trial alpha cup survey at Rossing South has commenced. A total of 100 cups have been installed, and will be retrieved for analysis in November. The alpha cups are placed below the soil surface and measure the effects of alpha radiation derived from radon gas present within the regolith.
