There has been no previous drilling for uranium in the Sua area. The area was targeted by Impact as being prospective for uranium deposits hosted by calcrete palaeochannels similar to those that host uranium mineralization at Yeelirrie in Western Australia and Langer Heinrich in Namibia. The targets are also prospective for playa-lake hosted uranium deposits such as Manyoni in Tanzania (Uranex).
Impact’s soil survey at Sua comprised 778 samples taken at 500mt intervals along lines 1km apart, and covering an area of about 320sqkm. The samples were analyzed for uranium by the MMI-M method at SGS Laboratories in Perth. The soil results have defined several areas with anomalous uranium-in-soil responses that contain elevated uranium-in-soil values of between 20 and 100 times background.
The largest area is close to the western edge of Sua Pan, trends north east to south west and is at least 16km long and 5km wide. The second largest area occurs in the central south of the area sampled, trends north west to south east and is up to 10km long and 3km wide.
Within these two large areas there are at least eight sub-areas that cover about 12sqkm, defined by uranium responses greater than 50 times background and up to 110 times background. Follow up field checking and selection of specific areas for drilling in the June 2010 quarter will commence shortly.
Impact has planned a drill campaign for the June 2010 quarter to test the uranium-insoil anomalies at both the Sua and Kodibeleng Prospects, as well as infill drilling at the Lekobolo Prospect where significant uranium results were recently returned from the company’s maiden drill program in Botswana.
