VANCOUVER, BC / ACCESSWIRE / April 27, 2023 / South Star Battery Metals Corp. ("South Star" or the "Company") (TSXV:STS) (OTCQB:STSBD), is pleased to announce a construction and permitting update for the Santa Cruz Graphite Mine currently in construction on the Phase 1 installations in Brazil, as well as the filing of the NI 43-101 technical report ("TR") of its maiden mineral resource estimate ("MRE") for the BamaStar Graphite Project located in Coosa County, Alabama, United States (the "Project").

Richard Pearce, CEO of South Star, commented, "Santa Cruz construction on the Phase 1 plant and mine installations is on time and on schedule through the end March 2023. All our licensing and permitting documents for Phases 2 and 3 for up to 50,000 of graphite concentrate have been submitted and are in technical evaluation. We are planning to have all our licenses and permits in hand by the end of 2023 so we can start the financing process for the future expansions. The BamaStar NI 43-101 technical report with the maiden mineral resource estimate is a fantastic result and confirms the potential for a significant deposit at this historical mine with at-surface mineralization that should be amenable to open pit mining techniques and low strip ratios. It's one of two projects in the continental United States with a defined mineral resource estimate. The drillers are set to get back out there in May 2023, and we are planning to get a NI 43-101 Preliminary Economic Assessment (PEA) completed by Q1 of 2024. The PEA will present our strategic plan of two mines, each producing 50,000 tonnes per year of concentrates, feeding a centrally located, value-add plant in the southeast United States and producing active anode material for electric vehicles, as well as purified/micronized and expandable graphite products. South Star has two scalable assets in strategic, stable, mining-friendly jurisdictions and the team to build and operate them in a safe responsible manner in partnership with communities and stakeholders. It's happening at the perfect time, when supply is constrained and demand is outstripping supply. This dynamic will be putting significant pressure on the graphite price in 2023 and for the foreseeable future. Santa Cruz will have the first new graphite production in the Americas since 1996 this year, and BamaStar is expected to be producing in 2027. Congratulations to the team for all the hard work!"

Santa Cruz Construction and Licensing Update
Construction through the end of March 2023 is on schedule and on budget for Phase 1 commercial production at the EOY 2023. Q2 2023 main work programs include:

  • Civil construction, foundations, and retention walls for the plant area;
  • Civil Infrastructure including entrance, security, additional offices, supply chain storage warehouse and contractor support area;
  • Electrical substation and internal electrical distribution network; &
  • Delivery of approximately 35% of the major equipment.

In addition, all environmental and mining documents for permitting and licensing of Santa Cruz Phases 2 and 3 have been filed with the Municipality of Itabela and the Brazilian Mining Agency ("ANM"). The consolidated operations environmental permitting process incorporating Phases 1, 2 and 3 is similar to the approved Phase 1 process, which was previously reviewed and approved in approximately 3 months.

The Company has also submitted the Planned Economic Analysis ("PAE") and the request for the final mining license ("concessão de lavra") for all 13 areas to the Brazilian Mining Authority ("ANM"). The proposed PAE doubles the Santa Cruz production capacity presented in the previously released PFS (March 2020) and incorporates a third phase of project development. The approval of the PAEs and mining licenses is the final step in securing the LOM mining license for each of the exploration claims and converting them to mining concessions. The planned production schedule follows:

  • 2 years with 5,000 tonnes per year ("tpy") of concentrates (Phase 1);
  • 2 years with 25,000 tpy of concentrates (Phase 2); &
  • Life of mine ("LOM") with 50,000 tpy of concentrates (Phase 3).

BamaStar NI 43-101 Technical Report with Maiden Mineral Resource Estimate
The independent mineral resource estimate was prepared by Caracle Creek International Consulting Inc. in accordance with Canadian Securities Administrators' National Instrument 43-101. There are no material differences between the Company's March 13, 2023 press release and the filed TR. The TR is available under the Company's SEDAR profile and on the Company's website.

South Star Battery Metals Corp., Thursday, April 27, 2023, Press release picture

Notes to Table 1 and Table 2 (#7 does not apply to Table 2):

  1. The independent Qualified Person for the Mineral Resource Estimate, as defined by NI 43-101, is Mr. Simon Mortimer, (FAIG #7795) of Atticus Geoscience Consulting S.A.C., working with Caracle Creek International Consulting Inc. The effective date of the Mineral Resource Estimate is March 7, 2023.
  2. These Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. The quantity and grade of reported Inferred Resources in this Mineral Resource Estimate are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as Indicated. However, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. Slight differences may occur due to rounding.
  3. Mineralized domains were based on lithological contacts. A cut-off grade of 1.0% graphitic carbon (Cg) was used for defining the mineralised domain, which was determined on the basis of core, surface trench, and surface sample pit assay geostatistics and drill core lithologies for the deposit.
  4. Geological and block models for the Mineral Resource Estimate used data from a total of 12 surface diamond drill holes (core), 29 trenches, and 90 surface sample pits. The drill hole database was validated prior to resource estimation and QA/QC checks were made using industry-standard control charts for blanks, core duplicates and commercial certified reference material inserted into assay batches by South Star Battery Metals.
  5. Quantities and grades in the Mineral Resource Estimate are rounded to an appropriate number of significant figures to reflect that they are estimations. Slight differences may occur due to rounding.
  6. An economic cut-off grade of 1.1% graphitic carbon (Cg) was calculated and applied to the resource block model for reporting purposes.
  7. The mineral resource estimates (Central and North zones) were constrained by conceptual pit envelopes using the following optimization parameters, as provided by South Star Battery Metals, and agreed to by the QP. Commodity prices used were (US$) $7,770/t graphite, pit slopes of 34 degrees in oxide and 54 degrees in fresh rock. Mining and processing costs (US$) were based on benchmarking from similar deposit types, utilizing a mining cost of $2.25/t (oxide) and $2.75/t (fresh rock), recovery of 97.2% graphite, with processing cost of $76.12/t (oxide) and $78.10/t (fresh rock), and a G&A cost of $2.00/t. Pit optimization was performed using Datamine's Studio NPVS software.
  8. The geological model comprises one mineralized domain split into five solids due to faulting, they are hosted by quartzites and sillimanite gneisses both with quartz veins and graphite lenses up to 40 m wide. Individual wireframes were created for each domain.
  9. The block model was prepared using Leapfrog Edge. A 15 m x 15 m with variable height block model was created and samples were composited at 1.0 m intervals. Grade estimation for graphite used data from trench and drill hole data and was carried out using Inverse Distance Squared Weighting.
  10. Grade estimation was validated by comparison of input and output statistics (Nearest Neighbour method), swath plot analysis, and by visual inspection of the assay data, block model, and grade shells in cross-sections.
  11. Density assignation was carried out for the mineralization domain using flat density by weathering domain, on the basis of 37 specific gravity measurements collected in 14 surface locations, and 51 specific gravity measurements collected during the core logging process, the average estimated density value within the strong weathering is 2.32 g/cm3 (t/m3), moderate weathering is 2.47 g/cm3 (t/m3), weak weathering is 2.62 g/cm3 (t/m3), while the fresh rock domain of the resource model yielded 2.80 g/cm3 (t/m3).
  12. The Mineral Resource Estimate was prepared following the CIM Estimation of Mineral Resources & Mineral Reserves Best Practice Guidelines (November 29, 2019).
  13. The NI 43-101 Mineral Resource Estimate and Technical report will be filed on Sedar within 45 days of this press release.
