Highlights:

  • BamaStar natural flake graphite concentrate was successfully upgraded to 99.95% fixed carbon, which is suitable for lithium-ion batteries and a variety of other value-add applications.

  • South Star is advancing a process flowsheet for producing coated, spheronized, purified graphite ("CSPG") using commercially available equipment and industry standard, proven technology with no special products or proprietary intellectual property.

  • The purification test results will be incorporated into the upcoming National Instrument 43-101 Preliminary Economic Assessment ("PEA"), which is scheduled for publication in September 2024.

  • South Star's immediate go-to-market commercial strategy is to produce high-quality graphite concentrates from Santa Cruz Graphite Mine in Brazil beginning in 2024 for a variety of industrial applications and sectors. Concurrently, technical product-development programs are continuing to advance the Company's vertically integrated midstream and downstream product suite for value-added applications using graphite concentrates from both Santa Cruz and BamaStar, with commercial sales planned by Q4 2026.

VANCOUVER, BC / ACCESSWIRE / August 22, 2024 / SOUTH STAR BATTERY METALS CORP. ("South Star" or the "Company") (TSXV:STS)(OTCQB:STSBF) is pleased to announce the positive purification results using a classic chemical purification process with its technology partner, Dorfner Anzaplan GMBH ("Anzaplan"). Chemical purification is the proven industry standard, which is currently the primary scalable, commercially-viable technology in use for improving the quality of concentrate graphite for a broad range of value-add applications, including lithium-ion batteries ("LiB"). Further to the March 23, 2024 press release, the purification test results will be incorporated into the upcoming PEA, which is scheduled for publication in September 2024.

Multiple kilograms of run-of-mine, natural flake graphite concentrate from the BamaStar Graphite Project ("BamaStar") with an average fixed carbon content of 93.47%, were purified to 99.95% C at Anzaplan's laboratory in Hirschau, Germany. The excellent purification results prove the material can be upgraded to a purity that is suitable for a broad range of battery applications including, alkaline, lead-acid and LiB, as well as value-add applications such as conductivity enhancement materials, expandable/expanded graphite, brushes, foils and gaskets. Additionally, the initial tests are unoptimized and resulted in extremely pure graphitic carbon with low levels of contaminants, as well as ease and flexibility of upgrading using dilute reagents. Additional test work, studies and optimizations are ongoing.
