Deep-South Starts Metallurgical Test Work on Ore from its Haib Copper Project in Namibia

Deep-South Resources Inc. (“Deep- South” or “the Company”) (TSXV:DSM) announces that Mintek has commenced its metallurgical test work on stockpile material from the Haib Copper Project in Namibia. The test work program is managed by METS Engineering of Australia.

Deep-South has provided Mintek with about 1.8 tons of ore sample from a large stockpile that was extracted during a previous sampling campaign. The sample contains chalcopyrite as the main copper mineral. The aim of the program is to test the amenability of the ore to microbially-assisted heap leaching. The test work will produce data for an eventual commercial pilot heap leach campaign.

Since 2003 heap leaching technologies have evolved substantially. Codelco has successfully used microbially-assisted heap leaching of copper sulfide ore containing chalcopyrite since 2014 at their Radomiro Tomic mine in Chile. Other operations in Chile have also piloted microbial-assisted heap leaching of chalcopyrite ores.

The program will also focus on testing the amenability of High Pressure Grinding Rolls (HPGRs) and test the acid consumption of the heap leaching process.

Test work summary:

The bulk head sample will be crushed down to -12.5 mm with a jaw crusher. The jaw crusher product will then be sub-sampled, and crushed with an HPGR to -5 mm, -3.35 mm and -2 mm, respectively. Sub-samples from each crush size will be removed for curing acid optimisation tests, assay-by-size (4 size classes), geomechanical tests and column leach tests. Additional head sample will be milled to 80% passing 75 ?m for chemical head assay by ICP-OES, sequential Cu (acid-soluble, cyanide-soluble and residual copper). Acid consumption (iso-pH) tests and batch stirred tank amenability tests will be performed on the head sample. Mineralogy (XRD and SEM) will be performed on the -2 mm head sample. The column leaching test will be carried out at a temperature of 60 ?C for a total duration of 200 days. However, interim results will be available weekly.
