Deep Yellow (ASX:DYL) completed reverse circulation infill drilling at the Tinkas prospect in Namibia, north-west of the Tumas project, on March 18, comprising 133 holes for 1,363 meters, according to a Thursday Australian bourse filing.

Uranium mineralization of over 100 parts-per-million grade of triuranium octoxide-equivalent was intersected in 38 holes, the filing said. Further infill drilling may be required to establish a resource in the Tinkas area.

The company also completed a high-resolution reflection seismic survey over the Condor Prospect at the Alligator River project in the Northern Territory to identify drill targets, per the filing. It aims to start drilling in the region in the June quarter.
