(\"South Star\" or the \"Company\") (TSXV: STS) (OTCQB: STSBF) is pleased to announce that it has received positive results for the laboratory bench scale filtered tailings tests performed on two simulated tailings samples from its Santa Cruz Graphite Project (Project) in Bahia, Brazil. Two tailings samples (+ 325 mesh and - 325 mesh) were generated and tested in laboratory facilities in Belo Horizonte, Brazil. \n\n\n \nThe goal of the testing program is to examine the potential for altering the proposed flow sheet from the process circuit presented in the NI 43-101 Preliminary Economic Assessment (PEA) to include a filter press and eliminate the requirement for a tailings storage facility. By incorporating filtered tailings technology, the majority of the water from the tailings would be removed and recirculated, and allow the dried tails to be placed together with waste rock in a co-disposal waste facility. \n\n\n \nCompany CEO Eric Allison stated \"We are very pleased with these initial results from our filtered tailings test program and their positive implications for utilizing dry stack tailings at Santa Cruz for both our trial mining plant and the final full-scale facility. Co-disposal of the waste should not only reduce the project's environmental impact, risk profile and physical footprint, but should streamline our permitting and licensing processes as well.\"\n\n\n \nThe Company plans to incorporate the results of the program into the prefeasibility report scheduled for completion in Q3 of 2019. \n\n\n \nFiltered Tailings Test Results\n\n\n \nFive scenarios were completed for the leaf filter tests varying solids densities, feed rates, vacuum pressures, and cake thickness:\n\n\n \n\n\n1.) -325 mesh sample at 10% solids \n\n\n\n2.)-325 mesh sample at 10% solids at higher feed rate and vacuum pressures \n\n\n\n3.)- 325 mesh sample at 20% solids \n\n\n\n4.)- 325 mesh sample at 20% solids with minimized cake thickness \n\n\n\n5.)+325 mesh sample at 10% solids \n\n\n\n\n \nThe tests result in cake with humidity varying between 23% to 35% and cycle times ranging from 19:23 to 49:47 minutes.
