Vancouver, B.C., Canada – TheNewswire – August 15, 2019 – Deep-South Resources Inc. (“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. Sorting test work results summary:
Steinert 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. Ore sorting was applied to the feed sample on a two-pass basis to generate a high-grade product and a high recovery product. The 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. The 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: The 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. Steinert recommends additional test work on a larger sample to confirm the sorting results and to allow for program optimization. Mr 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 a good option to extract the copper from the lower grade tails”. The Steinert KSS FL1 XT sensor sorter uses X-ray transmission, which measures the absorption (atomic density). The rock is conveyed on a belt in a closed system. The X-ray source is situated below the belt. The X-rays are emitted from below and pass through the rock and reach up the detector board over the belt. The detector uses a 3D laser sensor and a colour camera. The board will then detect the lower and higher grade material by calculating the X-ray absorption levels by the rocks. The lower grade material will then be conveyed on a specific belt and the higher grade material will be conveyed on another route.
