South Star Mining Corp. (“South Star” or the “Company”) (TSXV:STS) (OTCQB:STSBF) is pleased to provide an update for the advanced testing program on concentrates from its Santa Cruz Graphite Project located in the state of Bahia, Brazil. The test work is being carried out by Urbix Resources, LLC (“Urbix”) at its cutting-edge R&D facility in Mesa, Arizona and incorporates Urbix’s advanced purification and exfoliation technologies.
Last year, the Company submitted four different flake-size concentrates, previously produced during the Company’s pilot plant program, to Urbix for advanced testing. Phase 1 was a detailed characterization of each sample, including QEMSCAN, XRay Diffraction, Raman Spectroscopy and SEM among others. The results indicated a very high-quality graphite with minimum impurities and excellent suitability for further purification and value-added processing. The Second Phase has been focused on determining the ideal parameters for utilizing Urbix’s low-cost and environmentally friendly purification methodologies to achieve best results. A Design of Experiment (“DoE”) protocol with four key variables (time, temperature, chemical and reagent ratio) was developed based on a Six Sigma approach.
