Commenting on the PEA, Blake Hylands, P.Geo, CEO of Lithium Ionic, “We congratulate our team on advancing the Project to this stage in a short time span. As a Company, we are focused on being the next significant Brazilian lithium producer and this is reflected in the approach we have taken. Commencing with a highly attractive underground project will result in significantly less surface disturbance and the experience of CBL on the adjacent mine site provides a proven production model for developing the mining operation. The Company has a highly experienced team in Brazil that has taken numerous projects through the permitting and development process and as such the Project is well advanced in this regard. We believe the deliverables in this PEA are achievable.”
Blake Hylands, P.Geo., continued, "The robust results of our PEA marks a major de-risking milestone towards our goal of becoming a near-term supplier of high-quality spodumene concentrate to the global lithium and electric vehicle supply chains. The Bandeira deposit has demonstrated its technical simplicity and remarkable economic viability, placing it among the lowest-cost spodumene concentrate producers globally. Furthermore, this PEA showcases an impressive 20-year mine life from just one of our deposits. The Bandeira project will serve as a solid foundation for further growth as we continue to expand both the mineral resources and potential production scale through ongoing drilling and exploration in the region. We are rapidly advancing Bandeira through the next phases of development, with a Definitive Feasibility and Environmental Impact Assessment expected by the end of 2023, paving the way for the initiation of the environmental permitting process. As a proposed underground operation, Bandeira benefits from a minimal environmental footprint and an expected accelerated permitting timeline.”
Helio Diniz, President of Lithium Ionic, stated, “We believe that the best approach for all of our stakeholders is to develop a significant producing operation in the shortest possible time frame. We will continue to expand the resources and develop our other targets, which will represent future expansions to support what we believe will be a multi-generational production center.”

The Bandeira project engineering design contemplates dual underground mining operations. The primary orebodies, accounting for approximately 90% of the deposit, are proposed to be extracted using a bottom-up “sublevel stoping” method (Bandeira Sublevel Mine, “BSL mine”). Simultaneously, the secondary southeast orebody, comprising approximately 1.5 million tonnes, is expected to be mined using “room-and-pillar” technique (Bandeira Room and Pillar, “BRP mine”).
The BSL mine has been planned with two declines, extending along a NE/SW mineralized trend spanning 1.0 km. It is divided into 12 panels, each measuring 55 meters, and consists of two sublevels (see Figure 3).
The BRP mine features a single panel with approximate dimensions of 380 meters in length, 330 meters in width, and 10 meters in height. Access to the ore chamber will be provided through five crosscuts originating from the southern decline. Once fully operational, the BSL and BRP mines are expected to achieve a combined production of approximately 1.3 million tonnes per annum. Figure 4 shows the annual plant feed along with Li2O grade.

The mineral processing flowsheet is structured around a two-stage crushing circuit (comprising a Jaw crusher and Gyratory Cone crusher), ore size classification, the implementation of an ore sorter for coarse and medium materials, and the utilization of DMS (Dense Media Separation) for coarse and medium materials. Additionally, fines are subjected to gravity concentration with spirals. For a visual representation of the process, please refer to Figure 5, while Table 1 provides the specific design criteria for mineral processing.
The underground mine is anticipated to yield ore with an average Li2O grade of 1.23% over the Life of Mine (LOM), accounting for dilution at 16.8%. The ore sorting process will effectively purify the ore by removing undesirable dilution and non-lithium-bearing minerals like albite, feldspar, and quartz. This enrichment process will improve the lithium oxide grade to approximately 1.50%, ensuring a higher feed for the DMS I and II units. Based on the preliminary testwork program, Li2O recovery is projected to reach 67%, with an additional 10.7% achieved through gravity concentration in the fines fraction.

Updated Mineral Resource Estimate for Bandeira
The PEA is based on an updated MRE for the Bandeira project summarized in Table 2. The Bandeira MRE contains Measured and Indicated (“M&I”) resources of 13.72Mt grading 1.40% Li2O, containing 474,892 tonnes of Lithium Carbonate Equivalent (“LCE”), the benchmark equivalent raw material used in the lithium industry, in addition to Inferred resources of 15.79Mt grading 1.34% Li2O, or 523,118 tonnes of LCE.
The updated MRE for Bandeira is based on 204 diamond drill holes conducted on the Bandeira property until August 30, 2023. This compares to drill data from 120 holes in the previous MRE for Bandeira announced on June 27, 2023. This additional drilling significantly expanded the MRE, with the tonnes in the Indicated category increasing by 196% compared to the previous estimate.

|Contained LCE (t)|
|Measured + Indicated||13,720,000||1.40||474,892|
Notes related to the Mineral Resource Estimate:
- The spodumene pegmatite domains were modeled using composites with Li2O grades greater than 0.3%
- The mineral resource estimates were prepared in accordance with the CIM Standards, and the CIM Guidelines, using geostatistical and/or classical methods, plus economic and mining parameters appropriate to the deposit.
- Mineral Resources are not ore reserves and are not demonstrably economically recoverable.
- Grades reported using dry density.
- The effective date of the MRE was October 11, 2023.
- The MRE numbers provided have been rounded to the estimate relative precision. Values cannot be added due to rounding.
- The MRE is delimited by Lithium Ionic Bandeira Target Claims (ANM).
- The MRE was estimated using ordinary kriging in 12m x 12m x 4m blocks.
- The MRE report table was produced in Leapfrog Geo software.
- The reported MRE only contains fresh rock domains.
- The MRE was restricted by grade shell using 0.5% Li2O cut-off.
The complete NI 43-101 technical report associated with the PEA and updated MRE (the “Technical Report”) will be available on SEDAR+ at www.sedarplus.ca under the Company’s issuer profile, as well as the Company’s website at www.lithiumionic.com within 45 calendar days.
The Preliminary Economic Assessment is considered preliminary in nature and includes Inferred Mineral Resources that are considered too speculative, geologically, to have the economic considerations applied that would enable classification as Mineral Reserves. There is no certainty that the conclusions within the PEA will be realized. The PEA is based on the material assumptions outlined in this document. These include assumptions about the availability of funding. While the Company considers all of the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by the PEA can be achieved.
No mineral reserves have been estimated for the Project. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
