South Star Mining Corp announced the positive pre-feasibility study results for its 100%-owned Santa Cruz Graphite Project located in Southern Bahia, Brazil. The PFS presents a two-phased approach to production with an after tax NPV5% of US$81.2M, an IRR of 35% and a 4-year payback. The study used the current average basket price of US$1,287 per tonne which was held constant for the life of the project.

Phase 1 consists of a pilot plant with the capacity to produce 5,000t of concentrate per year, and the simple layout includes a small open-pit processing plant with filtered tails technology, waste storage facility for co-disposal of wasterock and filtered tails and civil infrastructure. The goal of the Phase 1 operations is to test and optimize the flowsheet, develop the key commercial relationships and optimize the production of products demanded in the marketplace, given the inherent, high-quality nature of the concentrates produced to date. Detailed engineering of the pilot plant was completed as part of the PFS.

Phase 2 is a larger plant with similar layout and technology, but with a capacity of 25,000t of concentrate per year. It's important to highlight that both Phases include the use of filtered tails technology and co-disposal of tailings with wasterock to avoid the requirement of a Tailings Storage Facility. This is essential in facilitating the permitting process and decreasing the environmental footprint of the facility.
