Project Location and Infrastructure


The Bandeira property covers 157 hectares, representing only approximately 1% of the Company’s large 14,182-hectare land package in the northern region of Minas Gerais State, Brazil, within the renowned “Lithium Valley” (see Figure 1). This area is recognized for its significant concentration of lithium-bearing pegmatites, making it one of the most promising lithium-producing regions globally. The Project benefits from excellent local infrastructure, which is critical for the efficient development and operation of the future mining activities.


The Bandeira site is well-connected via major highways, facilitating the transport of materials and personnel. The project site is approximately 570 kilometers from the port of Ilhéus in Bahia, which serves as a key logistical point for exporting lithium concentrate to international markets, including Shanghai, China. The proximity to Araçuaí provides access to essential services and amenities, enhancing operational efficiency.


A key infrastructure component for the Bandeira Project was secured in October 2023 through an agreement with Cemig Distribuição S.A. This agreement facilitates the construction and electrification of essential power infrastructure, including three kilometers of new transmission lines and a new substation adjacent to the future Bandeira mine and will ensure that the Project will be powered by low-cost, renewable hydroelectric power, aligning with the Company’s commitment to operating sustainably.

Mining Operations


The Bandeira project is designed to incorporate dual underground mining operations, ensuring efficient extraction of its deposits. The primary orebodies, representing approximately 83% of the total deposit, will be mined using a bottom-up sublevel stoping method. Concurrently, the secondary southeast orebody, which comprises approximately 0.98 million tonnes, will be mined using the room-and-pillar technique. Figures 2 and 3 present the annual mine production plan and the annual plant feed along with the Li2O grade, highlighting the project’s robust production capabilities.


Figure 2. ROM to Plant Feed and Li2O grade, %


Figure 3. Annual Production of Spodumene Concentrate grading 5.5% Li2O


Mineral Processing


The mineral processing flowsheet for the Bandeira project is designed to maximize lithium recovery and quality. It features a two-stage crushing circuit, which includes a Jaw crusher and a Gyratory Cone crusher, followed by dry screening classification. The coarse and mid fractions undergo ore sorting and Dense Media Separation (DMS) to produce a final SC5.5 Li2O concentrate. See Figure 4 for a visual representation of the process flowsheet.


The underground mine is expected to produce ore with an average Li2O grade of 1.16% over the Life of Mine, considering a mined dilution rate of 17.0%. The ore sorting process will enhance the ore quality by removing undesirable dilution materials, mainly schist, and non-lithium-bearing minerals such as feldspar and muscovite. This process improves the lithium oxide grade to approximately 1.50%, providing a higher-quality feed for the DMS while rejecting barren uneconomical waste. Based on Heavy Liquid Separation (HLS) bench scale test work completed by the Company, ore sorting and DMS pilot plant operations, the overall Li2O recovery is projected to reach 68.9%.


This efficient mineral processing approach ensures that we can maximize lithium recovery while maintaining the highest product quality. A higher quality chemical grade spodumene results in lower conversion costs therefore could potentially be sold at premium prices.

Project Economics and Sensitivities


The after-tax NPV8 for the Bandeira Project is $1.3 billion and IRR is 40%, assuming a 5.5% spodumene concentrate (“SC5.5”) price of $2,277/t. At an elevated price of $3,416/t, the NPV increases to $2.4 billion with an IRR of 62%, underscoring the project’s strong potential to benefit from rising lithium prices (see sensitivity analysis in Table 4).


Sensitivity analyses completed as part of the FS demonstrate that the Project’s value is strongly influenced by the selling price of spodumene concentrate. As demonstrated in Figure 5, while capital (CAPEX) and operational costs impact the Net Present Value (NPV), their effects are relatively minor compared to concentrate price fluctuations. Given the expected increase in lithium demand, Bandeira is well-positioned to capitalize on favourable market conditions and benefit from rising spodumene prices.

  Low Case Base Case High Case
LOM Avg Spodumene Price (SC5.5) $1,822/t $2,277/t $3,416/t
NPV $864 M $1.31B $2.41B
IRR 32.5% 40.3% 62.2%
Payback 4.3 years 3.4 years 2.2 years


Lithium Market Outlook & Spodumene Concentrate Price Forecast


A long-term spodumene concentrate price of US$2,277/tonne (5.5% Li2O grade) was used in the Feasibility Study. This long-term price forecast was obtained by Fastmarkets, one of the leading providers of global commodity pricing and market intelligence, in a report issued in April 2024.


The conservative spodumene concentrate selling price forecasts in the early years of the Bandeira mine life of $1,000-$1,600/t for the years 2026 to 2028 resulted in an increased payback period of the project compared to the PEA results from October 2023 (41 months compared to 14 months). Fastmarkets forecasts a higher long-term price based on strong demand and supply fundamentals, which is expected to benefit the Project’s overall economics in the future.


Lithium has emerged as a critical component in the global energy transition, with an annual consumption growth rate exceeding 25% over the past four years. Despite the supply of lithium compounds surpassing demand in 2023, the demand remains robust due to the increasing market penetration of electric vehicles (EVs). According to industry expert reports from Fastmarkets, Benchmark Mineral Intelligence and the International Energy Agency (IEA), this trend is expected to continue as EV adoption accelerates globally.


Bandeira Mineral Resource Estimate


On April 12, 2024, the Company reported an updated NI 43-101 mineral resource estimate for Bandeira of 23.68 million tonnes grading 1.34% Li2O (783kt lithium carbonate equivalent, “LCE”) in the Measured and Indicated category, with an additional 18.25Mt grading 1.37% Li2O (617kt LCE) in the Inferred category. This estimate was based on 233 drill holes, or 50,760 metres, drilled between April 2022 and March 2024.


The Bandeira FS proven and probable reserves, however, utilizes an NI 43-101 mineral resource estimate with an earlier data cut-off of November 13, 2023, which includes 186 drill holes (41,831 metres). This study mine plan is therefore based on a smaller estimate of 20.95Mt grading 1.35% Li2O (697kt LCE) M&I, in addition to 16.91Mt grading 1.40% Li2O (584kt LCE) Inferred (see Table 5).


The inclusion of the larger April 2024 MRE, as well as the additional drilling completed after the March 2024 data cut-off represents important future upside to the Project. The mine plan will be updated to incorporate the expanded mineral resource estimate in the next phase of project development.


The MRE was completed by independent Brazilian consultancy, GE21 Consultoria Mineral Ltda


Table 5: Bandeira Mineral Resource Estimate (base case cut-off grade of 0.5 % Li2O)


Category Resource (Mt) Grade (% Li2O) Contained LCE (kt)

Project Advancement & Optimization Opportunities


Lithium Ionic is committed to progressing the Bandeira Project towards production, aiming to become a leading lithium producer in Brazil’s Lithium Valley. This goal is supported by the following ongoing activities:


Permitting Process and Government Engagement: The Company continues to advance the permitting process and actively engage with governmental agencies. The next major permitting milestone, the approval of the Licença Ambiental Concomitante (LAC), is expected by early Q3 2024.


Next Phase of Engineering: The Bandeira Project will proceed to the next phase of engineering, focusing on implementing the optimization opportunities identified during the feasibility stage. This phase will include an expanded mineral deposit, which among other positive impacts could potentially extend the mine life. Significant opportunities have also been identified to streamline capital and operating costs, enhancing overall efficiency and optimization of the Project.


Feasibility Study Contributors and Methodology


Lithium Ionic engaged AtkinsRéalis (formerly SNC Lavalin) to coordinate the Feasibility Study, which covers engineering, process design, mine layout, risk assessment, and logistics for transporting the concentrate from Araçuaí, Minas Gerais, to the port of Ilhéus, Bahia, and then to Shanghai, China. The certification of mineral resources was conducted by GE21, with geologist Carlos José Evangelista Silva serving as the qualified professional for the estimation.


Underground mine studies were led by mining engineer Rubens Mendonça from Planminas, who signed off as the qualified professional for this discipline. The mineral processing studies were consolidated and defined by Tony Lipiec, Process Engineer and Vice President Global, Minerals & Metals Processing at AtkinsRéalis. Environmental studies were reviewed by Branca Horta from GE21, who signed off as the qualified professional for this area. The economic and financial model was validated by L&M Advisory, with João Augusto Hilario de Souza as the qualified professional.


The Feasibility Study considers Mineral Resources categorized as Measured and Indicated, converting 71% into Mineral Reserves. Mineral processing methodologies were developed based on extensive test work, including ore sorting and dense media separation using core drill samples in bench scale (HLS – Heavy Liquid Separation), ore sorting and DMS pilot plant tests at Steinert and SGS Geosol, respectively. Cost estimates for mine and plant equipment were based on vendor quotations, while power and FeSi prices were obtained through commercial consultations with Centrais Elétricas de Minas Gerais (CEMIG) and Washington Mills in the USA. The owners’ team costs were projected for 21 employees during the engineering and construction phases.


This comprehensive and collaborative approach ensures that the Feasibility Study encompasses all critical aspects, providing a robust foundation for the successful development and operation of the Project.
