(\"Deep- South\" or \"the Company\") (TSXV:DSM) announces results from the sorting test work on stockpile material from the Haib Copper Project in Namibia. The sorting test work is managed by METS Engineering of Australia and is undertaken by Steinert in Australia. Sorting was tested with a X-Ray transmission system by utilising Steinert's KSS FL1 XT sensor sorter.\n\n \n \nSorting test work results summary:\n\n \n \n\n\n--The test recovered 71.94% of the copper in 41.80% of the mass. It resulted in an upgraded Cu grade of 1.36%, which provided an upgrade factor of 1.73 times. \n\n\n\n \n \nSteinert tested a 20 kg sample with a head assay of 0.788% and a size of P100 31.5 + 8mm. The samples have been collected from a stockpile extracted from an adit dug in the higher grade area of the main Haib deposit. The samples have not been weathered and are considered representative of the sulphide mineralized material at Haib.\n\n\n \nOre sorting was applied to the feed sample on a two-pass basis to generate a high-grade product and a high recovery product. \n\n \n \nThe results showed that the first pass recovered 52.45% of the copper in 19.75% of the mass. It resulted in an upgraded grade to 2.091% Cu, resulting in an upgrade factor of 2.66.\n\n \n \nThe sorting was performed on a two-pass basis with the same algorithm but a more aggressive recovery setting applied to the \"waste of the first pass\". The cumulative first and second passes results were as follows:\n\n \n \nThe cumulative pass recovered 71.94% of the copper in 41.80% of the mass. It resulted in an upgraded Cu grade of 1.36%, resulting in an upgrade factor of 1.73. Grade in the remaining waste was 0.38% Cu.\n\n \n \nSteinert recommends additional test work on a larger sample to confirm the sorting results and to allow for program optimization.\n\n \n \nMr John Akwenye, Chairman of Deep-South stated that: \"The Steinert test is very promising. The high copper grade generated by nearly half of the mass treated opens up new options to extract the copper from the mineralized material. With the recent Mintek results, we also know that bio-assisted leaching is ...
