1.2 Reliance on Other Experts
The authors have not independently verified ownership or mineral title beyond the information that Lithium Ionic has provided. The Property description presented in this Report is not intended to represent a legal or any other opinion as to title.
The Authors are not qualified to express any legal opinion concerning Property titles or current ownership.
1.3 Property Description and Location
The Bandeira Project (The “Project”) covers 175 hectares within Lithium Ionic’s large land package of 14,182 hectares and is located between the towns of Araçuaí and Itinga within Brazil’s “Lithium Valley” - a hard rock lithium district that is quickly emerging as an important global lithium producer.
1.4 Accessibility, Climate, Local Resources, Infrastructure and Physiography
The Project is situated in the northeastern region of Minas Gerais State, Brazil, within the Jequitinhonha Valley, approximately 600 kilometres northeast of Belo Horizonte. Lithium Ionic fully owns the property. It is conveniently located about 75 kilometres south of the town of Salinas, with a population of approximately 42,000, and roughly 25 kilometres east of the town of Araçuaí, with a population of approximately 40,000. Access to the project is facilitated by well-maintained public and private roads, thanks to its proximity to National Roads 251 and 116.
The Project remains accessible year-round through a network of main and secondary service roads. National routes BR 116 and 262 provide access to the Port of Vitória in the State of Espírito Santo, located approximately 850 kilometres from the project site. This port offers potential export opportunities for any spodumene production from the project. Additionally, national roads BR 116 and BR 415 connect to the Ilhéus Port in the Bahia State, which is about 540 kilometres from the project and is an alternative shipping port option.
1.5 History
The Bandeira site and all other Mineral Tenures have not had any drilling activity before 2022.
1.6 Geological Setting and Mineralization
The Bandeira Project lies in the Middle Jequitinhonha River valley, northeastern Minas Gerais State, currently known as the Lithium Valley of Brazil. The region is part of the Eastern Brazilian

Pegmatite Province (EBPP), one of the largest pegmatitic provinces worldwide, with 150,000 km2 (cf. synthesis in Pedrosa-Soares et al., 2011). The EBPP is an outcome of magmatic and tectonicmetamorphic events that formed the Araçuaí Orogen from the Early Ediacaran (ca. 630 Ma) to the Late Cambrian (ca. 490 Ma). The significant EBPP pegmatite populations found within the Araçuaí Orogen have been grouped into twelve pegmatite districts (Pedrosa-Soares et al., 2011, 2023) that include residual pegmatites (representing late silicate melts released by fractional crystallization of parent granites) and/or anatectic pegmatites (formed directly from partial melting of country rocks).
The Itinga Pegmatite Field includes the spodumene mines and deposits of CBL (Companhia Brasileira de Lítio) and Sigma Lithium, as well as Lithium Ionic’s properties of its Bandeira Project, such as the Bandeira spodumene deposit. The lithium ore bodies exploited in the CBL’s underground mine, since the early 1990’s, display a closely spaced swarm of relatively narrow (6 m thick on average) but long (up to 700 m along strike) non-zoned spodumene-rich pegmatites (SRP) with on average 25 vol% of disseminated spodumene (Romeiro and Pedrosa-Soares, 2005). In the Sigma Lithium properties, where several large spodumene-rich pegmatites are found (e.g., Barreiro, Murial, Xuxa; Delboni Jr. et al., 2023), an open pit mine is currently being developed on the Xuxa SRP deposit (15 m thick x 1800 m long x 500 m downdip open).
1.7 Deposit Types
According to the most accepted petrologic-metallogenetic classification of pegmatites, published by Cerný (1991) and updated by Cerný and Ercit (2005) and Cerný et al. (2012), all the spodumene-rich pegmatites found within the Bandeira deposit, as well as in the whole Cachoeira Pegmatite Group, belong to the rare element class, Li subclass, and albite-spodumene type.
Although generally included in the LCT (Lithium-Cesium-Tantalum) family, the non- to poorly zoned spodumene-rich pegmatites (SRP) found in the Bandeira deposit, as well as all the orebodies mined in CBL’s Cachoeira Mine since the 1990’s, the Xuxa and other spodumene-rich deposits of Sigma Lithium (Sá, 1977; Delboni et al., 2023), and the Outro Lado deposit of Lithium Ionic, are rather poor both in Ta and Cs when compared with the complex zoned LCT pegmatites.
1.8 Exploration
Trench sampling program, rock chip sampling programs, structural mapping and geophysical surveys were completed on the Property. A total of 26 trenches were completed until 2024 at the Bandeira target by Lithium Ionic totaling 1,401 m. Field work included rock samples in the field and a preliminary field mapping of visible outcrops.
Some basic field data such as outcrop attitude (strike and dip), foliation and cleavage which located several occurrences of spodumene never previously known or reported. Since this initial discovery, Lithium Ionic rapidly advanced the Project with drill testing of the target(s) and the pegmatite system.

1.9 Drilling
All drilling activities conducted within the Bandeira Property until March 2024 have been incorporated into the Mineral Resource estimation process. It is important to note that any drill holes completed in 2024 after this date, as well as pending sample assay results, have not been considered in the present resource statement Table 1-1.

1.10 Sample Preparation, Analysis, and Security
Sample intervals in the mineralized zones are defined based on a 1.0m support. Mineralized samples must have a minimum length of 1.0m and a maximum length of 1.5m. In some specific situations, samples shorter than 1.0m can be generated.
Drill core samples are prepared and analyzed by an independent commercial laboratory (SGS Geosol). The SGS Geosol facility is certified in ISO 9001, ISO 14001, and ISO 17025. The sample shipment was delivered to the SGS Geosol facility in Vespasiano, Minas Gerais, Brazil, via a parcel transport company.
All samples received at SGS Geosol were inventoried and weighted before processing. Samples were dried at 105°C, crushed to 75% passing a 3 mm sieve, homogenized, split (jones riffle splitter), and pulverized (250 to 300 g of sample) in a steel mill to 95% passing 150 mesh.
Samples are prepared from NQ diameter drill cores (47.6mm core diameter). The sampling procedures described in this section reflect the current Standard Operational Procedures (SOP) in use by Lithium Ionic.
The sample batch composition includes 5 Quality Control Samples for every 30 regular samples. The Quality Control composition of the batches is described next:
-
Coarse (Preparation) and Fine (Analytical) Blanks: 6% of the batch, or two blanks per batch, one of each type.
-
Standards: 6% of the batch, or two standards per batch.
-
Crushed Duplicates: 3% of the batch, or 1 sample per batch.
-
Pulverized Duplicates: 3% of the batch, or 1 sample per batch.
Lithium Ionic has submitted Check Assay batches for analysis at the ALS Laboratory in Vancouver, British Columbia, Canada. This procedure is used to verify the reliability of the primary laboratory results by crosschecking it with a secondary reference laboratory.

In the QP opinion the sampling, sample preparation, security and analysis performed by Lithium Ionic and hired companies are suited for a Mineral Resource Estimation study. Quality Assurance procedures follow the industry’s best practices, and Quality Control results are within industry standards, attesting to the quality of the Database information.
1.11 Data Verification
Mr. Carlos José E. Silva, an independent QP for Geology Exploration and Mineral Resource Estimate, carried out a site visit on the Bandeira Project between 13 and 14 September 2023, and the 12th of December 2023. Lithium Ionic allowed unlimited access to the Company's facilities during this time.
Mr. Leonardo Silva Santos Rocha, an independent QP for Geology Exploration and Mineral Resource Estimate, conducted an additional site visit on the Bandeira Project on the 11th of April 2024. The main purpose of this visit was to check on the additional infill drilling and geochemical data included in the current Mineral Resource Estimate. Lithium Ionic allowed unlimited access to the Company's facilities during this time.
All verified procedures related to sampling management, storage, logging, sample preparation and assay were checked, and it is considered inside acceptance limits and in compliance with mineral industry practices. Rock-type descriptions fit with the checked mineralization style.
1.12 Mineral Processing and Metallurgical Testing
The ROM from the Bandeira Project's underground mine consists of pegmatite mineralized with minerals such as spodumene, albite, quartz, muscovite, K-feldspar, cookeite, and minor amounts of petalite. The technological characterization of this material to define the process flowchart for size reduction, classification, and concentration by dense media was carried out using 2" (50.8 mm) diameter drill samples.
The technological characterization was carried out through chemical and mineralogical analyses, physical tests to determine hardness, particle size distribution in crushing tests, level of abrasiveness and metallurgical tests to understand the response of the material when subjected to the simulation of the industrial process of concentrating the mineral, spodumene.
1.13 Mineral Resources Estimates
A set of solid-grade shells for estimation domains was created using a 0.3% Li2O (%) threshold. These interpretations were then transformed into a series of implicit 3D models, aligned with the dominant strike directions of 235° and 140°. Additionally, weathering modelling was performed, considering the information provided in the logs. The model was built from implicit modelling using the Leapfrog 2023.2 software.
The MRE was constrained by a grade shell using a cut-off content of 0.5% Li2O to report the underground mining resource, this value is commonly adopted for SRP-type pegmatites in the

Lithium Valley province.
The updated MRE contains M&I resources of 23.68Mt grading 1.34% Li ₂ O, containing 783.0 thousand tonnes (“kt”) of Lithium Carbonate Equivalent (“LCE”), the benchmark equivalent raw material used in the lithium industry, along with Inferred resources of 18.25Mt grading 1.37% Li ₂ O in the Inferred category, or 618.4kt of LCE (see MRE results in Table 1-2).
The MRE is based on 233 diamond drill holes comprising 50,760 metres of drilling completed between April 2022 and March 2024.

1.14 Adjacent Properties
The Itinga Pegmatite Field includes the spodumene mines and deposits of CBL (Companhia Brasileira de Lítio) and Sigma Lithium.
The Lithium ore bodies exploited in the CBL’s underground mine, since the early 1990’s, display a closely spaced swarm of relatively narrow (6 m thick on average) but long (up to 700 m along strike) non-zoned spodumene-rich pegmatites (SRP) with on average 25 vol% of disseminated coarse-grained spodumene (Romeiro and Pedrosa-Soares, 2005).
In the Sigma Lithium properties, where several large spodumene-rich pegmatites are found (e.g., Barreiro, Murial, Xuxa; Delboni Jr. et al., 2023), an open pit mine is currently being developed on the Xuxa SRP deposit (15 m thick x 1800 m long x 500 m downdip open).
1.15 Interpretation and Conclusions

polygonal that comprise the Bandeira Property and the Reasonable Prospect for Eventual Economic Extraction - RPEEE.
The dataset provided by Lithium Ionic to MRE encompassed data from 233 surface diamond drill holes (totalling 50,760 meters) executed by Lithium Ionic data available from 2022 until March 5[th] , 2024. This Bandeira database contains 8,693 assay intervals covering 8,168 meters.
A set of solid-grade shells for estimation domains was created using a 0.3% Li2O (%) threshold. These interpretations were then transformed into a series of implicit 3D models, aligned with the dominant strike directions of 235° and 140°. Additionally, weathering modelling was performed, considering the information provided in the logs. The model was built from implicit modelling using the Leapfrog 2023.2 software.
The Ordinary Kriging (OK) estimation method was used on the Li2O% and Density variables based on the structural analysis results.
The mathematical/geostatistical criterion for classifying the resource was based on:
-
The Measured Mineral Resource classification had as a reference the 50 meters of the Average Euclidean distance to sample (AvgD) used in ordinary kriging estimation with a minimum of five composites in at least three different drill holes.
-
The Indicated Mineral Resource classification had as a reference the 100 meters of the Average Euclidean distance to sample (AvgD) used in ordinary kriging with a minimum of five composites in at least three different drill holes.
-
The Inferred Mineral Resource classification is all remaining estimated blocks.
1.16 Recommendations
GE21 proposes the following recommendations for the continuous improvement of the Mineral Resource estimate:
-
A 50x50m infill drilling program in the domain of the indicated resource classification that will focus on resource delineation improvement.
-
A 100x100m infill drilling program in the domain of the inferred resource classification that will focus on resource delineation improvement.
-
A density campaign to measure the density of drill hole cores by drying the samples in an oven, as well as waterproofing them. Compare the results with the methodology used in the current project procedure to check whether there is a bias in the results.
-
Conduct an on-site density survey in the weathered zone.
-
An updated mineral resource assessment is currently underway through the ongoing infill drilling program.

The area of mining right number 832439/2009 is located on the border of the municipalities of Araçuaí and Itinga, in the valley of the Piauí River. This mining right was requested from the National Mining Agency in 2016. The Piauí River, which cuts through the western portion of the Lithium Ionic (MGLIT) area, serves as the border between the municipalities of Araçuaí and Itinga. The area of the Bandeira project therefore covers parts of both municipalities (Figure 4-2).

4.1 History of the Process and Legal Status of ANM Case n° 832.439/2009
The exploration right to the area which is covered by the ANM process No. 832.439/2009 was requested on 10/22/2009 by FALCON METAIS LTDA for the exploration of Lithium minerals in an area covered by the municipalities of Itinga and Araçuaí, state of Minas Gerais.
On 05/06/2014, after the study was rectified, permit No. 3785/2014 was published, authorizing the applicant to research the substance for a period of 3 (three) years.
The start of the research was promptly communicated on 05/07/2014. The annual fees per hectare, referring to the first permit validity period, were duly paid.
On 03/03/2017, Falcon Metais submitted a Partial Research Report with a request for an extension of the license, and the publication of the approval took place on 04/28/2020, extending the term of validity of the license for 3 (three) years.
The holder again communicated the start of the research work and requested the installment payment of the TAH due in July/2020. This was granted by the ANM.
On 12/28/2020, a request for the Total Assignment of Mining Rights from Falcon Metais Ltda to MGLIT Empreendimentos Ltda. was filed. And, due to the assignment now being effected, a requirement was published for the assignee and current holder of the process, MGLIT EMPREENDIMENTOS LTDA and presented a Term of Assumption of Debt referring to the 2 (two) current installments of TAH. The requirement was fulfilled on 05/04/2021.
Subsequently, the TAHs of July 2021 and 2022 were paid, and the installments were considered paid on 02/02/2022.
The expiration date of the research permit was changed from 04/28/2023 to 09/30/2024 by ANM resolution no. 76/2021, which determined the suspension of material and procedural deadlines due to the state of public calamity resulting from the COVID-19 pandemic.
The original essential data of the area in question is below, according to the website, on May 6, 2024, of the ANM's own Mining Registry (Figure 4-3).
With an area of 156.77 hectares, the area of the DNPM 832.439/2009 process has its envelope defined according to the data below (Figure 4-4):

6 HISTORY
6.1 History of Lithium
The history of lithium has an important relationship with Brazil. Between 1790 and 1800, José Bonifácio de Andrada e Silva, a native of the city of Santos, state of São Paulo, Brazilian naturalist, politician and scientist, was the one who first characterized and named spodumene and petalite, both anhydrous aluminum and lithium silicates, contained in samples from Sweden (ref. 1).
Most likely, prospectors already knew about lithium minerals in the Middle Jequitinhonha since the 18th century, although they did not know how to identify or value them. The occupation of the region was based on the discoveries of rock salt in the region of Salinas, and of gold in the Araçuaí River Valley from 1727 onwards, reaching the outskirts of Araçuaí in 1728. Since the early days of the mining of "chrysolite" (chrysoberyl) in the valley of the Piauí River, spodumene crystals have earned the nickname "rotten chrysolite" and "cambalacho", due to their similarity to chrysoberyl (cf. Sá, 1977 – ref. 2), as can still be heard today in conversations in the mines.
In 1823, Spix & Martius (1823) arrived at the headwaters of the Calhauzinho and Piauí Rivers in search of the sources of semi-precious stones, particularly chrysoberyl ("chrysolite"), which were already mined there, and described a "white granite with little mica, but with a lot of black tourmaline" (i.e., pegmatite).
In 1882, the first report of the occurrence of "trifana" (spodumene) in the Middle Jequitinhonha was due to Costa Sena (ref. 4). He identified "Andalusite, cimophana (chrysoberyl) and trifana, with sharp edges, in sands and gravel of the stream in the valley of the Piauí River, concluding that the primary deposits of these minerals would be located there".
Occurrences of spodumene were mentioned in the "Compendium of the Minerals of Brazil" (Ferraz, 1928 – ref. 5), among other pegmatite minerals. During the Second World War until the end of the Cold War, industrial beryl was widely exploited, starting in the region of Salinas and extending to the valleys of the Piauí and Jenipapo rivers (cf. Sá, 1977).
In Brazil, the production of lithium minerals began in the 1940s with the exploration of amblygonite (lithium phosphate) in the states of Ceará, Paraíba and Minas Gerais, to supply the chemical processing unit of Orquima (later Nuclemon), located in the neighbourhood of Santo Amaro, city of São Paulo. This lithium compound production unit operated until the late 1980s when it ceased its operation due to difficulties in the supply of raw materials and financial and environmental issues.
On pegmatites and the production of lithium minerals in the Jequitinhonha Valley, Haroldo de Sá, in his doctoral thesis, presented in 1977 at IG-USP, described the following:

"In 1950, the farmer Avelar Pereira, who was exploiting beryl in the Jenipapo Mine, found in the place called Fumal, to the right of the Middle Piauí, a very dark and very heavy material, which was analyzed by Mr. Khalil Afgouni and found that it was cassiterite. At the same time, it was also known that amblygonite had existed in some pegmatites in the Piauí valley."
-
"The cassiterite found near the Piauí stream attracted the attention of the companies Estanífera do Brasil and Produco (a subsidiary of Orquima) that settled in the region around 1952, and then began research and exploitation work on an industrial scale. At that time, the most important pegmatite bodies were the Fumal, Urubu and Generosa mines, the first two producing cassiterite and the last producing amblygonite."
-
"Glycon de Paiva, in 1957, identified lepidolite in the Urubu and Generosa mines, and the first tons of this ore were exported to Japan in 1959."
-
"At the Cachoeira mine (which is currently under CBL's mining right) spodumene production began in the late 1960s, to supply the demand of the domestic market."
-
"Petalite, abundant in the region, was called "white slag" by the miners and was often confused with feldspar. Its correct identification took place at the end of the 1960s, and it soon went into production for export purposes."
-
"Companhia Produco withdrew from the region in 1958, while Companhia Estanífera do Brasil maintained its activities until 1972, being succeeded by Companhia Arqueana de Minérios e Metais Ltda, which holds the mining and research rights in most of the area that comprises the valleys of the Piauí River, Jenipapo River and Tesouras River. This Company has today (i.e., in 1977) more than twenty pegmatite bodies producing petalite, spodumene, amblygonite, lepidolite, beryl, cassiterite and reduced quantities of tantalitecolumbite, employing about a hundred workers. The mines are semi-mechanized and some of them have mechanized development." (cf. Sá, 1977.)
Khalil Afgouni & Haroldo de Sá published, in 1978, a article on lithium in the journal Energy (vol. 3, Pergamon Press, see ref. 6), entitled "Lithium Ore in Brazil", in which they state, at the end of the abstract of the work, that: “Another new use is in lithium batteries for electric cars and, if this application becomes a reality, Brazil will be a big consumer, ranking at the same level as the most developed countries in the world with the advantage of being one of the few countries capable of producing its own raw material.”
Correia-Neves, Pedrosa-Soares & Marciano published, in the Brazilian Journal of Geosciences (1986, ref. 7), a synthesis of studies on the Eastern Pegmatite Province of Brazil, applying, for the first time, petrological and metallogenetic concepts still current in the approach to litiniferous pegmatites, with emphasis, in particular, on the metallogenetic specialization of the Itinga Pegmatite Field for the production of spodumene and petalite, compared to other more lithiumpoor pegmatite populations in the provinc
In 1985, Companhia Brasileira de Lithium (CBL) acquired from Companhia Arqueana de Minérios

e Metais Ltda, the mining rights and assets of the areas that include the Cachoeira Mine and its surroundings, having started producing spodumene concentrate in the early 1990s. In 1991, CBL acquired Nuclemon's chemical unit, which was paralyzed, and transferred it to Divisa Alegre, in the state of Minas Gerais, for processing spodumene concentrate. The first systematic study of the structural control of pegmatitic bodies and the variation of spodumene granulation at the Cachoeira Mine (CBL) was presented in the master's thesis of Júlio Romeiro (1998, IGC-UFMG).
In 2012, Sigma Lithium acquired several mining rights from Arqueana de Minérios e Metais Ltda, starting an exploration work to produce spodumene concentrate for export. In the second quarter of 2023, the concentration unit's commercial operation began to produce 270,000 tpa of spodumene, treating approximately 1.5 million tpa of ore from the Xuxa mine.
To encourage the development of the lithium production chain, the Brazilian government created the Lithium Decree, which was in force from 1992 until 2022.
Currently, in Brazil, there are three producers of spodumene concentrate: CBL, AMG, and Sigma Lithium, all of which are located in Minas Gerais. CBL is the only one that produces lithium compounds, such as carbonate and hydroxide.

Notes related to the Mineral Resource Estimate:
-
The effective date of the MRE is June 24, 2023.
-
The classification of the current Mineral Resource Estimate into Measured, Indicated and Inferred is consistent with the current 2014 CIM Definition Standards - For Mineral Resources and Mineral Reserves.
-
All figures are rounded to reflect the relative accuracy of the estimate, and numbers may not be added due to rounding.
-
All Resources are constrained by continuous 3D wireframe models (constraining volumes) and are considered to have reasonable prospects for eventual economic extraction.
-
Mineral resources which are not mineral reserves do not have demonstrated economic viability. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
-
The pit optimization results are used solely to test the “reasonable prospects for economic extraction” by an open pit and do not represent an attempt to estimate mineral reserves. There are no mineral reserves on the Project.

It is envisioned that parts of the Bandeira deposit may be mined using open pit mining methods. In-pit mineral resources are reported at a cut-off grade of 0.5% Li2O within a conceptual pit shell,
-
The results from the pit optimization are used solely for the purpose of testing the “reasonable prospects for economic extraction” by an open pit and do not represent an attempt to estimate mineral reserves. There are no mineral reserves on the Property. The results are used as a guide to assist in the preparation of a Mineral Resource statement and to select an appropriate resource reporting cut-off grade.
-
It is envisioned that parts of the Bandeira deposit may be mined using underground mining methods. Underground (below-pit) Mineral Resources are estimated from the bottom of the pit (base of transition mineralization) and are reported at a base case cut-off grade of 0.8% Li2O. The underground Mineral Resource grade blocks were quantified above the base case cut-off grade, below the constraining pit shell and within the constraining mineralized wireframes.
-
Based on the size, shape, location and orientation of the Bandeira and Outro Lado deposit, it is envisioned that the deposit may be mined using low-cost underground bulk mining methods.
-
Bulk density values were determined based on physical test work from each deposit model and waste model.

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 182 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.

7 GEOLOGICAL SETTING AND MINERALIZATION
7.1 Regional Lithium History and Geology
The Project lies in the Eastern Brazilian Pegmatite Province (EBPP), located in terranes of the Araçuaí Orogen (Figure 7-1 and Figure 7-3). The EBPP, one of the largest pegmatitic populations in the world with c. 150,000 km2, contains pegmatite districts located in eastern Minas Gerais (c. 90% of the whole province), southeastern Bahia, and Espírito Santo States of Brazil.

in Brazil since the last decades of the 17th century, when green tourmalines, initially mistaken for emeralds, were found by the explorer Fernão Dias Paes Leme in the region of São José da Safira, a pegmatite district very rich in gem-quality elbaite (Li-bearing tourmaline). Long after, in the first decades of the 19th century, pioneer naturalists and geologists, such as Eschwege, Spix, Martius, and Saint-Hilaire, described pegmatite gem deposits located in the Jequitinhonha and Doce river valleys. In 1818, Spix and Martius reached the headwaters of the Calhauzinho and Piauí rivers in the Araçuaí region (Figure 7-4), searching for the gemstones’ primary sources, particularly chrysoberyl (then called “chrysolite” locally) that was already mined there. They found a “white granite with little mica, but rich in black tourmaline” (i.e., pegmatite). At that time, spodumene (discovered and named by the Brazilian mineralogist José Bonifácio de Andrada in a volume of the Journal der Chemie, 1800) was already called “rotten chrysolite” by pioneer prospectors and gemstone diggers (“garimpeiros” in Brazilian Portuguese) of the Jequitinhonha Valley. In 1866, Charles Hartt described the N45E-trending structure of the mica schists hosting very coarsegrained “granite” veins between Araçuaí and Itinga. In 1882, Costa Sena published the first paper directly referring to spodumene (also called “triphane” at that time) in the Middle Jequitinhonha region, after identifying “andalusite, cymophane (chrysoberyl) and triphane with sharp edges, in sands and gravels from streams of the Piauí river valley” and suggested that the primary deposits would also be located there. Several spodumene occurrences, among other pegmatite minerals, of the Middle Jequitinhonha Valley are described by Luiz Caetano Ferraz in his “Compendio dos Mineraes do Brasil”, published in 1928.
The importance of pegmatites as economic mineral deposits greatly increased in Brazil from the Second World War, due to the large production of mica, beryl, and quartz to supply the military industry of allied countries, to the end of the Cold War in early 1990’s. Just after the Second World War, in 1946, the largest pegmatitic populations of Brazil were grouped into provinces by Glaycon de Paiva. Among them the Eastern Brazilian Pegmatite Province was first defined. Since then, more than one thousand pegmatites have been mined there for gemstones, cassiterite, Li and Be ores, Nb-Ta oxides, industrial minerals (K-feldspar, muscovite, albite, quartz), collection and rare minerals, dimension stone, and minerals for esoteric purposes.
Historical milestones in the discoveries and mining of lithium deposits in the Araçuaí-Itinga region were reported by Haroldo de Sá in his PhD thesis (1977). According to him:
- “The discoveries and production of cassiterite, lepidolite, and amblygonite in pegmatites of the Piauí river valley (e.g., Fumal, Generosa, Jenipapo, and Urubu) by the Estanífera do Brasil and Produco companies dated back to the early 1950s. Although spodumene has been known for a long-time by gem diggers (“garimpeiros”), who called it “cambalacho” or “crisólita podre” (i.e., rotten chrysolite in reference to its similarity to chrysoberyl), its commercial production only started at the end of the 1960s at the Cachoeira mine (then owned by Companhia Estanífera do Brasil) to supply the increasing demand of the national market.
Petalite, formerly called “escória branca” (white scoria) and very often mistaken for feldspar, was correctly identified at the end of the 1960’s and immediately mined for exportation by the

Companhia Estanífera do Brasil until 1972, followed by Companhia Arqueana de Minérios e Metais Ltda. Around 1977, this mining company has more than twenty distinct pegmatite bodies producing petalite, spodumene, amblygonite, lepidolite, beryl, cassiterite and columbite-tantalite.” For his PhD thesis (1977), Haroldo de Sá compiled map, sections and other data from the archives of the Companhia Arqueana de Minérios e Metais Ltda. and produced the first geochronological data for the local granites and pegmatites (whose similar ages, around 500 Ma, is evidence of a genetic link between them). He also produced the first geochemical data (K, Rb, Cs) for minerals of non-economic and pegmatites with mineralization of petalite, spodumene, lepidolite and/or pollucite. His spatial interpretation of the distribution and zoning of different Lirich pegmatites, even with present-day knowledge, remains realistic.
Khalil Afgouni, an outstanding pioneer of the lithium mining in Brazil and the owner of Companhia Arqueana de Minérios e Metais Ltda, together with Haroldo de Sá published a farseeing article entitled “Lithium Ore in Brazil” in the prestigious magazine Energy in 1978 (vol. 3, pp. 247-253). In the article, they predict that “another new use (for that metal) is in lithium batteries for electric cars and, if this application becomes reality, Brazil will be a big consumer, ranking at same level as the most developed countries in the world, with the advantage of being one of few countries producing its own raw material.” Although this is not yet a full reality, the remarkable increase in lithium ore production in the Jequitinhonha Lithium Valley is a result of the invaluable heritage of Arqueana’s discoveries of world-class lithium deposits.
The assets were later bought by CBL (Cachoeira mine) in the early 1990’s and, more recently, by Sigma Lithium (Xuxa mine, and other spodumene and petalite deposits such as Barreiro, Maxixe, Murial, and others). That heritage continues to drive new companies to the region, whose exploration efforts have led to the discovery of subsurface spodumene deposits in areas lacking outcrops, such as the Bandeira deposit of Lithium Ionic.
Since the early 1980s, the region encompassing the Eastern Brazilian Pegmatite Province (EBPP) has been completely covered by systematic geological mapping (in 1:100,000 scale) and experienced an outstanding increasing in scientific studies supported by robust analytical data. That allowed genetic and metallogenetic links between pegmatite populations and the tectonomagmatic events of the regional geological evolution to be established. In fact, the EBPP is the result of the magmatic and tectono-metamorphic events that formed the Araçuaí Orogen from the Early Ediacaran (ca. 630 Ma) to the Late Cambrian (ca. 490 Ma).
These events comprise the regional deformation, metamorphism and partial melting of sedimentary and volcanic successions deposited in the Tonian-Cryogenian precursor (rift to passive margin) basin system and the Ediacaran orogenic (arc-related) basins (Figure 7-2), as well as of the continental basement. The melting events resulted in the production of huge volumes of orogenic granitic rocks and thousands of pegmatites grouped into five supersuites (G1 to G5; Figure 7-1, Table 7-1).

metamorphicanatectic processes that generated granites and pegmatites show two contrasting distributions of U-Pb ages for detrital grains of zircon (Figure 7-2). One is a classic multimodal age spectrum of a basin system evolved from continental rift to passive margin, represented by the Macaúbas Group and Jequitinhonha Complex.
The other age distribution shows an unimodal spectrum typical of orogenic basins largely filled by material from a rather dominant zircon source (e.g., an active magmatic arc), representing the Salinas Formation and Rio Doce Group that host most Li-bearing pegmatites in the EBPP (Figure 7-1). The Salinas Formation, comprising quartz-mica schist (metapelite) with lenses of calcsilicate rock (metamarl), metawacke (metasandstone) and metaconglomerate, is the main host unit of Lirich pegmatites in the whole EBPP, including the spodumene-rich pegmatites of the Bandeira deposit of Lithium Ionic.
Tectono-metamorphic events and the G1 to G5 granitic supersuites of the Araçuaí Orogen play distinct roles in relation to pegmatite abundance, distribution, genesis, and metallogenetic specialization, imposing important prospecting constraints with regards to metallic potential of distinct pegmatite populations along the EBPP (Table 7-2).
The G4 is the most important granitic supersuite related to Li-rich pegmatites, followed by the G2 supersuite, while the G5 and G1 supersuites are related to Be-rich pegmatites generally free of or poor in Li-minerals. Tourmaline-bearing pegmatites are widespread in the EBPP, except in some clusters of Be-rich and Li-rich pegmatites.
The G4 intrusions and batholiths show the classical distribution of granitic facies, from pluton root to top, found in other Li-rich pegmatite districts around the world, comprising biotite leucogranite, two-mica leucogranite, muscovite leucogranite, albite leucogranite and pegmatoid granite. Apatite, beryl, tourmaline, and garnet occur in the pegmatoid granites, and muscovite-albite leucogranites. The Salinas Formation is also the main host unit of G4 intrusions associated with Li-rich pegmatites (Figure 7-1).
7.1.1 Pegmatites
Granitic pegmatites represent silica-saturated magmas variably rich in H2O and bearing fluids, as well as in other hyperfusible (fluxing) components (e.g., Li, Na), crystallized in rather closed chemical systems (cf. Cerný, 1991; London, 2008). The EBPP comprises the two known genetic types of pegmatites, both formed during the evolution of the Araçuaí Orogen: i) the anatectic pegmatites generated directly from the partial melting of country rocks; and ii) the residual pegmatites, representing late silicate melts released by fractional crystallization of parental granites. Genetic affiliation and other criteria allow pegmatite districts to be distinguished in the EBPP (Figure 7-3; Table 7-2).

The anatectic pegmatites are coarse-grained quartz-feldspathic bodies (i.e., granitic leucosomes) hosted by migmatitic gneisses and micaschists, mostly formed in the collisional tectonometamorphic event (585 – 540 Ma) and in the post-collisional thermal event (540 – 490 Ma). Therefore, their spatial distribution, and genetic and metallogenetic features are directly

related to the melted country rocks. Conversely, the residual pegmatites, especially those enriched in rare elements, have restricted spatial distributions and genetic links directly related to the distinct granite types from which they ultimately inherited their geochemical characteristics and metallogenetic specializations (Figure 7-3, Figure 7-2).
Therefore, residual pegmatites released from peraluminous, subalkalic to alkalic, hydrous, S-type, two-mica leucogranites formed from the partial melting of metasedimentary rocks might have a rather distinct metallogenetic specialization (e.g., richer in Li, Cs, Ta, Sn, and P) in relation to residual pegmatites (e.g., richer in Be, F, and Fe) from metaluminous, high-K calc-alkalic, ferroan, relatively anhydrous, A-type, amphibole-biotite granites formed from the partial melting of mainly igneous rocks. The first case (S-type granites) refers to Li-bearing pegmatites associated with the G4 and G2 supersuites, while the second (A-type granites) stands for the Be-bearing (but Li-free) pegmatites comprised by the G5 supersuite (Figure 7-3, Table 7-2).

The EBPP was subdivided into twelve pegmatite districts based on the mineral production, genetic and metallogenetic affiliation and classification, parental granite type, host rocks and metamorphic regime, and crystallization ages of a relatively large and clustered pegmatite population (Figure 7-3; Table 7-2). Most of them are districts of residual pegmatites of the rare element class, distinguished by their affinities with the LCT (Lithium-Cesium-Tantalum) or NYF (Niobium-Yttrium-Fluorine) geochemical-metallogenetic families that, in turn, are related to distinct types of parental granites.

completely circumscribed or very close to A-type and I-type G5 intrusions, encompassing granitic and igneous charnockitic (orthopyroxene-bearing) rocks with features of magma mingling-mixing involving mafic melts.
Contrastingly, complex LCT pegmatites and albite-spodumene-rich pegmatites (SRP) are found in the external aureoles of S-type intrusions mostly composed of two-mica leucogranites with pegmatoid cupolas, generally hosted by metasedimentary rocks of the greenschist to amphibolite facies. Among the EBPP Li-bearing districts, the Araçuaí Pegmatite District stands out by having the largest historical and current production of lithium ore and the only world-class spodumene deposits of Brazil. Those deposits include the CBL, Sigma, and the newly discovered deposits by other companies, such as the Bandeira and other spodumene-rich deposits of Lithium Ionic Corporation.
The Araçuaí Pegmatite District includes several LCT pegmatite fields distinguished by their mineral production, pegmatite types and subtypes, and pressure-temperature (P-T) conditions of both the regional and contact metamorphisms (Figure 7-4). Besides complex LCT pegmatites, spodumene-rich pegmatites (SRP) are known in the Curralinho, Itinga, Neves-Tesouras and Salinas pegmatite fields. However, the Itinga Pegmatite Field remains the most important for spodumene production and prospecting, owing to the outstanding abundance of non-zoned to poorly zoned SRP ranging from a few to dozens of meters thick, hundreds to a few thousand meters in length along strike, and dozens to hundreds of meters in downdip width. Many spodumene orebodies mined by Arqueana, CBL and Sigma, as well as those discovered by Lithium Ionic at Bandeira and other targets, belong to the SRP (or albite-spodumene) type.
7.2 Structural Geology
In the Araçuaí Pegmatite District (Figure 7-4), the present-day structural framework was established after four deformation events (D1, D2, DG, and DNt). Two of them (D1, D2) are directly related to the regional tectono-metamorphic evolution of the Araçuaí Orogen in the Ediacaran-Cambrian. The third deformation event (DG) was caused by the widespread and voluminous intrusions of Cambrian G4 granites that caused thermal metamorphism and significant structural disturbance on the regional fabrics along areas relatively close to granitic stocks and batholiths (Pedrosa-Soares et al. 1987, 1993, 2011; Alkmim et al., 2006; Santos et al., 2009; Peixoto et al., 2017). Much later, the last deformation event (DNt) resulted from neotectonics reactivation in the Late Tertiary (Saadi and Pedrosa-Soares, 1989). The EdiacaranCambrian deformation events (D1, D2, and DG) formed the structural framework that passively hosts the rare element pegmatites in the Araçuaí District (Figure 7-4). The much younger neotectonic deformation (DNt) reworked prior structures in upper crustal levels in the Late Tertiary (Miocene), forming normal faults and graben basins (e.g., the Virgem da Lapa Graben, Figure 7-4) filled by the fluvial to lacustrine sandstone-mudstone piles of the São Domingos Formation that reach more than 100 m in thickness (Saadi and Pedrosa-Soares, 1989; Pedrosa-Soares, 1997). Locally, neotectonic faults may cut and displace blocks with pegmatite

deposits.
The D1 deformation results from regional tectono-metamorphic processes imposed by compressive stresses during the collisional stage (580-540 Ma) of the Araçuaí Orogen. Megascopic to macroscopic D1 structures are asymmetric tight folds with long limbs and short hinges, parasitic folds, and ductile shear zones related to thrust ramps and oblique to transcurrent strike-slip domains.

evolved from a cleavage to the schistosity S1 (Figure 7-5) that contains the L1 mineral/stretching lineation. S1 is generally (sub)parallel to the layering (S0) along D1 fold limbs, becoming an axialplane surface in fold hinges (Figure 7-5). Anastomosed and S-C foliations characterizes higher strain shear zones syn-kinematic to S1. Although it generally is a very penetrative structure, the S1 foliation also provides host surfaces for pegmatites.
Distinct metamorphic regimes related to the D1 deformation of schists and gneisses rich in micas have been recognized in the region encompassing the Araçuaí Pegmatite District (PedrosaSoares et al., 1984, 1993, 1996; Costa et al., 1984; Costa, 1989; Santos et al., 2009; Peixoto et al., 2017). In the western and southwestern sectors of the region (Figure 7-4), the S1 schistosity shows syn-kinematic (syn-S1) assemblages with Fe-rich garnet (almandine), staurolite, kyanite and/or sillimanite. Such index-minerals series is typical of a medium pressure and medium temperature (MP/MT) metamorphic regime (Figure 7-4). This, together with quantitative geothermobarometric data, characterize the M1 metamorphic event as a syn-collisional (syn-D1) Barrovian-type (MP/MT) metamorphism dating between 575 – 550 Ma. P and T increase from c. 3.5 kbar at 450 °C in the garnet zone at the southwest of Francisco Badaró, passing northeastwards through the staurolite, kyanite and sillimanite zones, and reaching up to 8.5 kbar at 650 °C at the southeast of Coronel Murta (Figure 7-4).
In the northeastern and northern sectors of the region, the S1 schistosity shows syn-kinematic (syn-S1) assemblages with biotite, Mn-rich garnet (spessartine), andalusite, cordierite and/or sillimanite. Such index-minerals series is typical of a low pressure and high temperature (LP/HT) metamorphic regime (Figure 7-4). From the most northeastern andalusite zone to the southwest of Itinga, quartz-feldspathic leucosomes with aplitic to pegmatitic textures formed from the breakdown of muscovite along the S1 foliation of cordierite-quartz-mica schists. Northeastwards, through the andalusite-cordierite, cordierite-sillimanite, sillimanite, and K-feldspar zones, increasing metamorphism and partial melting of quartz-mica schists formed migmatitic paragneisses in the eastern tip of the Itinga Pegmatite Field (Figure 7-4). Regionally, the metamorphic event (M2) records a low-P/high-T metamorphism with pressures from 2 kbar to 5.5 kbar under temperatures from 400 °C to 700 °C, at around 540-530 Ma. The M2 metamorphism reached partial melting conditions on quartz-mica schists of the Salinas Formation with increasing anatexis rates that formed leucosome-rich migmatites (diatexites) in the easternmost sector of the Araçuaí Pegmatite District. This implies that, in deeper crustal levels, the widespread anatexis on the Salinas Formation could have produced large volumes of S-type granitic magmas in the late collisional to post-collisional stages of the Araçuaí Orogen. Indeed, the time interval of the M2 metamorphism (540-530 Ma) fits well with the oldest ages of G4 granites (535-525 Ma). This, together with the fact that the M2 metamorphism culminated in partial melting of quartz-mica schists and paragneisses in the easternmost Araçuaí Pegmatite District, indicate that the S-type G4 magmas were formed from the anatexis of thick metasedimentary packages in deep levels of the Salinas Formation.
Along the boundary between the M1 and M2 metamorphic domains (Figure 7-4), the syn-S1

mineral assemblages include almandine and/or staurolite and andalusite and/or cordierite, characterizing an intermediate-low pressure (Buchan-type) metamorphic regime (IP/IT, Figure 7-4) transitional between the M1 Barrovian-type (MP/HT) and the M2 low-P/high-T (LP/HT) metamorphic regimes found in the Araçuaí Pegmatite Districts. Bearing in mind the relations between distinct pegmatite populations, their metallogenetic specializations and metamorphic regimes (Cerný, 1991; Cerný et al., 2012), such metamorphic characterization is of great importance for prospecting different rare element pegmatites, as Li-rich pegmatites are typically found in terranes with relatively low-P/high-T metamorphism.

The D2 deformation developed from the late collisional to the post-collisional stages of the Araçuaí Orogen, when increasing decompression conditions, imposed by the orogen gravitational collapse, gradually replaced the tangential D1 compressive stresses. In the Araçuaí Pegmatite District, the D2 deformation comprises mostly brittle structures, such as the S2 spaced cleavage, joint families, and normal faults, as well as large open folds (flexures). The spacing between surfaces of the S2 cleavage ranges from less than one centimeter to decimeters (Figure 7-5). Locally, S2 may be very well developed in micaschists, becoming a tight crenulation cleavage to schistosity. The S2 spaced cleavage and other brittle structures, as being more open surfaces than the S1 schistosity, provided host surfaces for Li-rich pegmatites, generally the thicker ones, in the Itinga Pegmatite Field.
The latest Cambrian deformation event (DG) was caused by the intrusion of large volumes of Stype magmas that formed the G4 granites and cut across and disturbed the regional framework imprinted by the D1 and D2 deformations. The DG event deformed the regional structural trend of the host rocks around granitic plutons, forming radial fractures irradiating from the granitic plutons, and imprinting ring-shaped fracture systems that reworked regional structures around the intrusions. All these DG structures can host late orogenic rare element pegmatites.
During emplacement and cooling, the G4 plutons caused contact metamorphism on their country rocks and released residual silicate melts that formed pegmatites that either crystallized within the parental granite or migrated outwards and were hosted by D1, D2 and DG structures of the Salinas Formation and other metasedimentary units. While barren and beryl-bearing pegmatites are found both within parental G4 granites and country rocks, the Li-bearing pegmatites have been only found in places rather far from (> 1 km) granite massifs, emplaced in the Salinas Formation and other metasedimentary units. The G4 batholith emplaced along the whole eastern boundary of the Araçuaí Pegmatite District is formed by multiple coalescent plutons and places an eastern limit for the occurrence of Li-bearing pegmatites.
Regionally, the deformational events formed large structures with distinct implications for the occurrence and structural control of pegmatites in the Araçuaí District, such as the Salinas Synclinorium, the Lagoa Nova Anticline, and the Minas Novas - Araçuaí - Itinga Corridor (Figure 7-4).
The axial zone of the Salinas Synclinorium shows the best-preserved section of the Salinas Formation, comprising non-deformed to weakly deformed metawacke, metapelite and metaconglomerate, metamorphosed in the biotite and garnet zones of the low greenschist facies. This low-grade metasedimentary section reaches up to 2 km in thickness, with no evidence of pegmatite along the synclinorium keel. However, a Li-rich pegmatite cluster, including SRP bodies, was recently found to the east of the Salinas Synclinorium, along the andalusitecordieritebearing, low-pressure/high-temperature metamorphic zone of the Curralinho Pegmatite Field (Figure 7-4).
In the case of the Lagoa Nova Anticline, although there are LCT pegmatites emplaced along its structural surfaces, no SRP was yet found there, much probably due to the rather unfavorable

pressure-temperature conditions of the regional and contact metamorphisms (between the medium PT (MP/MT) and intermediate PT (IP/IT) regimes).
The Minas Novas - Araçuaí - Itinga Corridor, in turn, plays a special role in the understanding of the structural control and the most favourable pressure-temperature conditions for the SRP occurrence in the Araçuaí Pegmatite District. That corridor has been characterized as a flowershaped transpressive (during D1) to transtensive (during D2) structure (Pedrosa-Soares et al., 1993, 1996; Alkmim et al., 2006) with the S1 foliation dipping to SE in the NW flank, and to NW in the SE flank (Figure 7-4).
In the Itinga Pegmatite Field, the S1 schistosity and S2 spaced cleavage show NE-trending strikes, with the S1 schistosity dipping to NW and the S2 cleavage dipping to SE (if they have not been disturbed by later deformations, i.e., DG and DNt). The S1 foliation, as well as the S2 spaced cleavage and other brittle surfaces (i.e., the flat-lying and subvertical joints) host many Li-rich pegmatites, with the thicker SRP bodies generally emplaced in more open surfaces of brittle structures.
The regional metamorphism associated with the S1 schistosity gradually increases from southwest to northeast along the corridor, reaching c. 3.5 kbar at c. 550 °C at the andalusite cordierite zone in the Piauí river valley, where the contact metamorphism was imposed by G4 granitic intrusions also under relatively low-pressure conditions. All those tectono-metamorphic and magmatic features favorable to SRP occurrence characterize the Itinga Pegmatite Field where several of the most important spodumene deposits already found in Brazil are located, such as those of the CBL and Sigma, and the SRP deposits of Lithium Ionic.
7.3 Local Geology
Field mapping in the Bandeira area revealed the existence of two geological units: (i) Salinas
Formation, characterized by banded quartz-mica schists with lenses of calcsilicate rocks; and (ii) G4 Supersuite, represented by an extensive pegmatite dike-swarm (pegmatite veins) composed of spodumene-rich orebodies and some non-mineralized pegmatites (Figure 7-6).

Figure 7-6 – Geological Map of the Bandeira Deposit

Owing to the significant weathering typical of tropical regions, the surface of the Bandeira area predominantly comprises recent residual soils resulting from the decomposition of the underlying rocks. The schist residual soil is a red to brown fine-grained (silt to clay) eluvium. In contrast, the pegmatite soil is typically a whitish, fine to coarse-grained, powdered eluvium, with a composition dominated by quartz, kaolinized feldspar and altered muscovite. In cases of lithium mineralization, this soil can also contain fine-grained, partially to almost wholly weathered spodumene fragments.
Based on the few exposed outcrops, the Salinas Formation in the Bandeira area is composed of biotite schist and cordierite-biotite schists of gray color and medium-grained size. When these rocks contain a higher concentration of mica, the schistosity is more penetrative and tends to be more fractured (Figure 7-7a). When the amount of quartz is greater, a preserved original bedding can be observed marked by the alternance of dark biotitic and light quartzfeldspathic layers (Figure 7-7b). Cordierite-biotite schist was also identified in the Bandeira target, and they are characterized by the enrichment of millimetric to centimetric cordierite porphyroblasts (Figure 7-7c), which can be stretched along the schistosity (syn-tectonic) or undeformed and latestage (post-tectonic). Based on observations in the drill cores it is also possible to verify the presence of calc-silicate rocks interlayered in the schists, which can be classified in three types (based on the mineralogy): (i) biotite-quartz schist; (ii) quartz-biotite schist; and (iii) cordieritequartz-biotite schist.

The pegmatites in the Bandeira target constitute a swarm of several dikes with variable thicknesses (metric to decametric). They are normally concordant to the Salinas Formation schistosity (5055°NE/40-50°NW). The nature of the contact between the pegmatite and the host rock is abrupt and sharp (Figure 7-3a). Records of the pegmatites mineralized in lithium in the Bandeira area (i.e., Spodumene-Rich Pegmatites – SRP) can be observed in some exposed outcrops that show centimetric coreless to greenish spodumene crystals, with whitish colour when weathered. In such veins, it is common the occurrence of euhedral prismatic centimetric crystals with a preferred orientation indicative of mineral growth orthogonal to the borders of the dike (Figure 7-3b).
Based on the observations from these outcrops and the intercepts from the drill cores, it is possible to define the Bandeira mineralized bodies as non-zoned pegmatitic dikes with a simple and consistent mineralogy composed essentially of albite (33%), perthitic K-feldspar (25%), spodumene (19%), quartz (15%), and muscovite (5%). Accessory phases (3%) vary from petalite, columbite, tantalite, cassiterite, apatite, tourmaline, and sphalerite. The log analysis unveiled well preserved spodumene crystals of variable sizes, typically centimeter-scale and disseminated throughout the rock. Notably decimeter-sized crystals also occur (Figure 7-3b).

The concordant SRP pegmatites in the Bandeira area are dominantly concordant with the regional schistosity (S1) but discordant bodies, with similar strike and dipping to southeast, also occur. The best example are the pegmatites observed in the southeastern region (Figure 7-3), where a more flattened large discordant body fed smaller intrusions that dips towards southeast. These discordant bodies share identical mineralogical composition with the concordant bodies, leading to the interpretation as both products of the same coeval magmatism.

pegmatitic population of the Itinga Pegmatite Field (e.g., Sá, 1977; Afgouni and Sá, 1978; CorreiaNeves et al., 1986; Afgouni and Marques, 1997; Pedrosa-Soares et al., 2009, 2011, 2023; Romeiro, 1998; Quéméneur and Lagache, 1999; Romeiro and Pedrosa-Soares, 2005; Dias, 2015; Chaves et al., 2018; Luiz, 2023). The Cachoeira Pegmatite Group comprises a SRP swarm that has been mined at least since the 1970’s by the Arqueana Company (Figure 7-10), followed by the production of spodumene ore in industrial scale by CBL since 1993 (Figure 7-11). It is yet the best characterized spodumene deposit in Brazil, providing solid information to support the mineralization model that was applied to the exploration work on the Bandeira deposit (Figure 7-4).

The typical SRP orebodies of the Cachoeira Pegmatite Group are non-zoned but rather inequigranular pegmatites composed of spodumene (on average 23 vol%), perthitic microcline, albite, quartz, and muscovite, generally totalizing more than 95% of the whole orebody volume. Montebrasite, beryl, cassiterite, columbite-tantalite, cookeite, zabuyelite and petalite are scarce accessory minerals.

spatial distribution of parallel to subparallel, locally branched orebodies showing lateral and vertical offsets among them (Figure 7-11 and Figure 7-12). They are roughly tabular bodies with lens-shaped terminations, ranging from decimeters up to 30 m in thickness orthogonal to dip, from a few meters to many hundreds of meters in length along strike, and up to many hundreds of meters downdip. The Cachoeira pegmatites were emplaced in the Salinas Formation that consists of banded cordierite-quartz-mica schist with intercalations of calcsilicate rock, recording P-T conditions suitable for SRP occurrence. In the Salinas Formation, the main host surfaces for pegmatites are the regional foliation (schistosity) S1 and the S2 spaced cleavage, although late joint surfaces can also host SRP bodies (Figure 7-10, Figure 7-11, and Figure 7-12).

The tectonic structure of the Salinas Formation behaved passively during the intrusion of Li-rich magmas that crystallized as spodumene-rich pegmatites, which in turn do not record any evidence of ductile or brittle deformations (Figure 7-11 and Figure 7-12), except for small faults that locally cut pegmatite contacts and may be related to the latest D2 or DG deformations (Figure 7-12; see also section 7.2).

Based on available information from the Cachoeira Pegmatite Group and CBL’s underground mine (Figure 7-10 and Figure 7-12), a mineralization model for spodumene-rich pegmatites (SRP) was conceived to assist in the exploration work on the Bandeira target. After a soil geochemistry campaign, Li anomalies roughly parallel to the Cachoeira SRP swarm were revealed and, together with lithological and structural data from few outcrops, old diggings, and new exploration trenches (Figure 7-13) provided the basis for a very successful drilling campaign that discovered dozens of new SRP bodies rather close to each other from the near surface to more than 800 m in depth. The newly discovered Bandeira deposit comprises spodumene-rich orebodies, arranged along the same structural trend of Cachoeira’s SRP swarm (Figure 7-14).

Following the regional NE-SW structural trend, the Bandeira deposit comprises SRP swarms of NE-striking orebodies mostly hosted by and concordant with the NW-dipping schistosity (S1), but also some discordant SRP emplaced along the SE-dipping fracture system (S2 spaced cleavage), as well as a few SRP bodies hosted by late flat-lying joints (Figure 7-14). The Bandeira pegmatites are tabular bodies with convex lens-shaped terminations, arranged in tight and staggered (enechellon) swarms, locally with branched connections linking ore bodies. Single SRP bodies normally reach hundreds of meters in length along the strike, ranging in thickness from a few decameters to decimeters, with the discordant SRP bodies tending to be thicker than the concordant ones. With known downdip-width up to 800 m, several Bandeira SRP bodies remain open in depth. The exploration drilling work revealed two main SRP swarms in the Bandeira

The host rocks of SRP orebodies in the Bandeira deposit are banded to laminated cordieritequartz-mica schists, locally containing disseminated sulphide and/or graphite-rich bands, with intercalations of massive calcsilicate rocks (Figure 7-15 and Figure 7-16). Most cordierite forms ellipsoidal (egg-shaped) stretched poikiloblasts syn-kinematic to the regional S1 schistosity (Figure 7-15).
The banded to laminated quartz-mica schists represent metamorphosed sand-mud sediments, and the calcsilicate rocks are metamorphosed Ca-rich carbonate-mud sediments (marls). They show sharp contacts with the SRP orebodies that generally are concordant to the regional S1 foliation (often parallel to the compositional layering S0) but are also hosted by the S2 cleavage or foliation (Figure 7-16). The host schists may be enriched in decussate muscovite and/or biotite, black to green tourmaline, and recrystallized cordierite along narrow (cm to dm) fringes of contact metamorphism imposed by pegmatites (Figure 7-17). Although the host schists may be anomalous in lithium content close to pegmatites, they show no Li-ore mineral.

The Bandeira spodumene orebodies show a rather simple mineralogical assemblage (Figure 7-16 and Figure 7-17), consisting of medium - to very coarse-grained spodumene phenocrysts, reaching up to 35 vol% on average, within a fine - to medium-grained matrix mostly composed of albite, perthitic K-feldspar (microcline), quartz, muscovite, and petalite, summing up to 95 vol% of the total matrix. The scarce accessory (mainly montebrasite, and Nb-Sn-Ta oxides) and

secondary minerals (cookeite, sericite, zabuyelita, Fe-Mn oxides, clay minerals) generally comprise less than 5 vol% in total. In drill cores, the spodumene crystals are mostly free of hydrothermal and weathering alterations and very poor in mineral inclusions (Figure 7-16 and Figure 7-17)). Conversely, surface outcrops, shallow diggings and exploration trenches cutting SRP bodies generally show weathered spodumene (Figure 7-13), forming pseudomorphs composed of white clay (kaolinite and montmorillonite). Rare spodumene-quartz intergrowth (SQUI) may be found associated with spodumene crystals (Figure 7-17). Petalite has been found in SRP's drill cores and thin sections, mostly occurring in the matrix as very fine- to fine-grained (sub-millimetric to 1 cm) crystals (Figure 7-17) and, more rarely, as coarser crystals locally found in rather restricted intervals.
The thicker SRP bodies may show a lithium-barren and thin marginal zone rich in albite, generally rather discontinuous, followed inwards by a thick internal zone rich in disseminated spodumene (although spodumene may also be more ROM in some domains than others along the internal zone). Owing to the upward migration of H2O-rich fluids, flat-lying SRP sections close to the hanging-wall contact, as well as the top termination (“head”) of high-angle dip bodies, may show metasomatic units with miarolitic cavities that partially replaced the primary mineral assemblage. Many SRP bodies lack the external lithium-barren zone, showing disseminated spodumene along virtually the whole orebody (Figure 7-16 and Figure 7-17)). Unidirectional solidification textures outlined by tabular to telescope-shaped spodumene crystals are common in the Bandeira’s SRP orebodies. Thin albite-rich pegmatites, barren to poor in lithium, are also found in the Bandeira pegmatite swarms.

8 DEPOSIT TYPES
The following text and illustrations were compiled from Pedrosa-Soares et al. (2023) and complemented with data from Lithium Ionic public and internal reports, if not otherwise specified. According to the most accepted petrologic-metallogenetic classification of pegmatites, published by Cerný (1991) and updated by Cerný and Ercit (2005) and Cerný et al. (2012), all the spodumene-rich pegmatites found within the Bandeira deposit, as well as in the whole Cachoeira Pegmatite Group, belong to the rare element class, Li subclass, and albite-spodumene type.
Although generally included in the LCT (Lithium-Cesium-Tantalum) family, the non- to poorly zoned spodumene-rich pegmatites (SRP) found in the Bandeira deposit, as well as all the orebodies mined in CBL’s Cachoeira Mine since the 1990’s (Romeiro and Pedrosa-Soares,
2005), the Xuxa and other spodumene-rich deposits of Sigma Lithium (Sá, 1977; Delboni et al., 2023), and the Outro Lado deposit of Lithium Ionic, are rather poor both in Ta and Cs when compared with the complex zoned LCT pegmatites (e.g., Generosa, Jenipapo, Murundu, Urubu and others) found in the Itinga Pegmatite Field (cf. Sá, 1977; Romeiro, 1998; Quéméneur and Lagache, 1999; Dias, 2015) and elsewhere (e.g., Cerný 1991; London, 2008; Cerný et al., 2012).
The SRP deposits consist of non-zoned to poorly zoned spodumene-rich pegmatites with spodumene reaching up to 35 vol% on average, and the total modal content of spodumene, albite, K-feldspar, quartz, and white mica (muscovite and/or Li-rich mica) summing up more than 90 vol% of the whole body. Therefore, SRP bodies are very poor in accessory minerals, which are generally represented by Li-micas, Li-phosphates, Nb-Sn-Ta oxides, cookeite, carbonate and graphite. They are also poor in secondary (metasomatic) units due to their rather fluid-poor (anhydrous) nature (Figure 7-12, Figure 7-16, and Figure 7-17).
As a corollary, the scarcity of rare elements, except for lithium, imposes constraints on the geochemical prospecting methods to be applied on searching for spodumene-rich deposits. Conversely, the high Li content (1.4 wt% Li2O on average) in SRP-type magmas promotes a significant decrease in the crystallization temperature and viscosity of the silicate melt, leading to the high mobility that allows such a Li-rich magmas to crystallize as very large but relatively narrow SRP bodies, with hundreds to thousands of meters in length and width, but only decimeters to a few decameters in thickness.
Therefore, for prospection and exploration work related to spodumene-rich deposits, it is very important to distinguish between the non- to poorly zoned spodumene-rich pegmatites (SRP, i.e., pegmatites of the albite-spodumene type) and the complex zoned LCT pegmatites.

9 EXPLORATION
Fieldwork was conducted in the Bandeira deposit with an approach encompassing chip rock sampling, soil sampling, a trench program, structural analysis and a drilling program. These activities aimed to achieve a more profound comprehension of the local geology and the identification of potential spodumene-rich pegmatites.
9.1 Chip Rock Sampling
Despite the extensive residual soil cover, the field mapping led to the recognition of pegmatites in artisanal mines (garimpos), in situ outcrops or fragments dispersed on the surface. Spodumene crystals were only identified in pegmatites found in artisanal mines and surrounding areas. The chip rock map (Figure 9-1) shows the location of each collected sample, with their respective lithium content (Li ppm), and the location of the outcropping pegmatites, mineralized in spodumene or not.

9.2 Soil Sampling Program
The soil program in the Bandeira area was conducted in two distinct campaigns. In the first survey, the lines were oriented along the azimuth N120° and were spaced at regular intervals of 250

meters. Within each of these lines, samples were collected every 50 meters. In the second campaign, the lines were oriented at N150°, were spaced at regular intervals of 150 meters, and the samples were collected every 25 meters.
A total of 537 samples were collected in the Bandeira area, and the lithium content in the soil varied from 10 ppm to 573 ppm. Calculations based on the distribution of the results indicated a subdivision of the content as low grade (< 69 Li ppm), low to moderate grade (70-107 Li ppm), moderate to high grade (108-152 ppm), and high grade (> 153ppm). Based on the distribution of the results, it was possible to interpret at least five high-grade anomalous zones that represent more favourable spots to prospect spodumene-rich pegmatites (Figure 9-2). These anomalous regions are strongly oriented along the NE-SW direction, which is the same strike of the regional foliation and the mapped pegmatites in the Bandeira area and adjacent region.

9.3 Trench Program
After the soil geochemistry survey, a trench program was devised to investigate the anomalous areas. A total of 26 trenches were executed, totaling 1733 m of excavated lines (Table 9-1). The trenches were preferably positioned on top of the soil anomalies and the majority were positive, with pegmatite intercepts (Figure 9-3). Due to the high weathering, the exposed pegmatites are very decomposed in some trenches, exhibiting a characteristic whitish colour that shows a significant contrast with the horst schist (see an example of trench ITTRE-22-006 in Figure 9-4 a

and b). These pegmatites are friable, and it was possible to diagnose only quartz, kaolin and flake muscovite. In other trenches, however, it was possible to observe more preserved pegmatites, with visible spodumene centimetric crystals (see an example of trench ITTRE-22-001 in Figure 9-4 c and d). Independent of the conservation state, as part of the procedure, every pegmatite higher than 30cm mapped in the trench was sampled to verify the Li content (see channel sampling line on the pegmatite excavated in trench ITTRE-22-001 shown in the scheme of Figure 9-4 e).
In addition to confirming the presence of pegmatites and studying their mineral composition, the trenches played an important role in determining the strike and dip of the dikes. This valuable information contributed significantly to the mapping of the area and provided a higher level of confidence in planning the boreholes for the drilling campaign.

9.4 Structural Analysis
Although lacking outcrops, the few exposures of mica schists from the Salinas Formation are very relevant and helpful to understanding the structures in the Bandeira deposit. Ductile and brittle structures are recognized. The ductile structures were produced during the progressive metamorphism related to the syn-collisional phase of the Araçuaí orogen. In contrast, the brittle structures are younger and have been interpreted as related to the gravitational collapse of the orogen during the post-collisional phase. The structural map of the Bandeira target (Figure 9-5) shows the distribution of the structures and the projection of the non-exposed pegmatites. In that case, the attitude of each body was measured considering the interpreted geological model.

The pegmatite veins are projections of the known intrusions based on the intercepts in drillholes. The attitude of each vein is based on the modelled veins.
The dominant ductile structural feature is the pervasive regional schistosity (S1), which exhibits a consistent orientation in both strike and dip across the entire area (modal: N50E/45NW). The stretched lineation (Lx) complements the ductile structural framework, often manifested as elongated micas or ellipsoidal cordierite porphyroblasts crystalized along S1. This lineation is downdip and indicates tectonic transport along the NW-SE direction.
The brittle structures are represented by a series of fractures, occasionally joints, that intersect the S1 schistosity and seem part of a conjugate system (Figure 9-6). Each structure was denoted as either F1 (fractures with a moderate dip to the southeast) or F2 (sub-vertical fractures), and their presence and prevalence may vary depending on the outcrop. The F1 structure seems more pervasive in the entire region, which also allows the interpretation of these structures as related to the development of a cleavage fracture system (secondary foliation S2). All these planar structures in the Bandeira area (S1, F1 and F2) consistently display a standard orientation along the NE-SW strike, with variations only in their dip angles.
Understanding the structural patterns in the host rocks is crucial for prospecting pegmatites since these structures serve as the surfaces that guide the migration of the silicate magmatic residues. Consequently, they profoundly influence the shape and continuity of the pegmatite bodies enriched in spodumene in the Bandeira area.

9.5 Geophysical Surveys
A small-scale geophysical survey consisting of Induced Polarization was conducted on both Bandeira and Outro Lado prospects in 2022.
Induced polarization (IP) and resistivity (RES) are commonly used to delineate the resistive or conductive portions of the pegmatites subsurface. Although common in use by some operators, the inverted data is not always helpful or productive in the very early stages of exploration; however, in the case of Lithium Ionic, there were sufficient outcrops to measure some attitude data, so the general trend of the pegmatites could be extrapolated using the subsurface IP anomalies. Energy-induced data were acquired through the dipole-dipole arrangement in two distinct areas: Area 1 involved six lines and totaled 5,150 m linear. Area 2 had five lines totaling 2,850 m linear profiling executed in March and April 2022.
The principle for this prospecting method is based on the injection of current through several electrodes into the ground. Data acquired depended on the resistivity values at each point, terrain

geometry and the electrodes’ geometric arrangement (arrays). For an uninterrupted flow of current, the induced polarization depends on the terrain’s impedance and the current’s frequency. The induced polarization can be measured in the time and frequency domains. Despite being complex, IP resembles the discharge of a capacitor (time domain), or the impedance variation of an alternating current (frequency domain) can be measured. Once processed, the raw data can be viewed in 2D or, if available, in a 3D environment. Resistivity and induced polarization data were acquired in Areas 1 and 2 with the dipole-dipole arrangement (AB=MN=25 m). The map in Figure 9-7 shows the location of the lines and measuring stations of the Chargeability and Resistivity data. Some pseudo-sections of apparent chargeability and apparent resistivity 2D models of the processed data are shown below.

10.1 Lithium Ionic Drilling Campaigns
As of November 13, 2023, Lithium Ionic has successfully executed 242 diamond drill holes within the Bandeira Property, as detailed in Table 10-1 and Figure 10-1 to Figure 10-3.
All diamond drilling activities conducted within the Bandeira Property until March 2024 have been incorporated into the Mineral Resource estimation process. It is important to note that any drill holes completed in 2024 after this date and pending sample assay results have not been considered in the present resource statement.

10.2 Drill Type
All drilling operations were conducted using core techniques with HQ and NQ core size specifications, featuring a 63.5mm and 47.6 mm core diameter, respectively. This approach was chosen to ensure the retrieval of pristine and representative core samples, which are essential for accurate geological logging, adequate sample support, and to secure a material supply for future metallurgical testing purposes.
10.3 Drilling Companies in Bandeira Project
Three Brazilian-based companies undertook the 2022-2024 Drill Program in Bandeira:
-
Servdrill Perfuração e Sondagens Ltda (http://servdrill.com.br/);
-
Servitec Foraco Sondagem AS (https://www.foraco.com.br/);
-
GEOSOL Ltda (https://www.geosol.com.br).
10.4 Drill Collar Monuments
All Drill Core Monuments were surveyed by a Differential GPS and the monuments were placed by the driller once the hole had been completed.
10.5 Drillhole Surveying
The drill holes were drilled with a plunge between 50º to 90º. Core holes are generally oriented at azimuth 340° and 152°, perpendicular to both general orientations of the pegmatite intrusions.

MGLIT used the REFLEX GYRO IQ downhole survey tool to obtain all downhole survey data. According to The REFLEX GYRO-IQ™ website, the tool can maintain high accuracy of surveys. The device is connected to a cloud-based data hub, with a secure chain of custody and QA/QC application with real-time access to drilling survey data. Data transfer from field to office ensures minimum clerical errors related to processing and interpretation.
MGLIT rented the downhole Reflex tool and completed all hole surveys at various locations and attitudes, where all necessary surveys were done in real-time. MGLIT staff had quick access to results through the cloud-based data hub. The design of the high-speed survey allowed Lithium Ionic field staff (including geologists and drillers) to obtain the following:
-
Survey speeds of more than 150 meters surveyed per minute,
-
There were no significant issues with the accuracy of results, which was confirmed once holes were plotted on a 3D modelling software.
-
Continuous survey data comes from the tool’s north-seeking sensors assisted with GPS.
-
The report’s authors have no way to verify the accuracy of the survey method; hence, the authors will rely on the statements and information provided by MGLIT.
10.6 Core Orientation
MGLIT began implementing REFLEX ACT III to establish core orientation for drill holes within the Bandeira project after July 2023. As of the effective date, core orientation has been determined for four drill holes. Lithium Ionic has consistently integrated core orientation into its drilling program and will now prioritize its application in strategically significant sections of the geological model moving forward.”
The Reflex core orientation system is based on recovering the core barrel orientation after a run. The Reflex orientation tool begins the orientation process by inserting the device in the core barrel using a specially made shoe. The tool records core barrel orientation each minute during a core run. The Reflex sleeve that attaches to the upper drill rod measures the direction of the top-ofhole using built-in accelerometers. Upon completion of a run, the drill string is left undisturbed while the communication tool, which is on the surface, counts down the time to the next reading; after this, the barrel can be withdrawn. On the surface, the tool is inserted into the end of the barrel, and the barrel is rotated until it indicates that the barrel is in the same up-down position as it was in the hole. The core, barrel, and shoe are then marked using a level to confirm verticality upward position. After the line is split, the top of the core marks is transferred along the length of the recovered core.
The Report’s authors have no way to verify the accuracy of the orientation method; the authors will rely on the statements and information provided by MGLIT.

10.7 Drill Core Chain Custody
The drill cores are primarily stored in plastic or wooden boxes.
It is always transported by the drilling companies from the drilling site directly to the MGLIT core sheds in Araçuaí. MGLIT’s staff receives all core boxes delivered.
10.8 Core Logging Procedures
Lithium Ionic adheres to a core logging methodology, carried out by geologists and technicians.
In summary, the following procedures are conducted:
-
Preparation of drilling site.
-
Collar Drilling location.
-
Verify and validate meterage and quality of drill cores in the field.
-
Core survey drilling.
-
Photographs of the core box.
-
Detailed petrographic and geological structural core logging.
-
Geotechnical logging (RQD, weathering types).
-
Sample geochemistry logging programming and QA/QC procedures.
-
Drill core density determinations for each programmed sample.
-
Core sample preparation for geochemistry analysis.
-
Logistics protocols for sending samples to the laboratory.
Each procedure has its respective sheet and is stored in digital form within Lithium Ionic customized database system.
10.9 Ore Drilling Intercepts
Drill spacing typically ranges from 50m to 150m, with narrower spacing observed in the central portion of the drill pattern and wider spacing towards the pattern’s edges. The ore intercepts vary in thickness, ranging from approximately 85% of the true width to nearly the true width of the mineralization.
The average pegmatite intersection spans from 0.3m to 40m, with an average true thickness of about 5m. In total, 760 mineralized intercepts from diamond drill holes (DDH) were utilized for modelling the 34 mineralized solids within the Bandeira Project. Each solid was assigned a numerical code in the tag column.
Figure 10-4 to Figure 10-7 list the mineralized intervals from Bandeira drill holes that were incorporated into the 3D modelling of the mineralized solids (Figure 10-8 and Figure 10-9).

10.10 QP's Comments
No significant drilling, sampling or recovery factors would impact the outcome of the drilling results and the estimated MRE (covered in section 14).
In the Author’s opinion, based on a review of all possible information, the drilling procedures put in place by MGLIT meet acceptable industry standards, and the data can be and has been used for Geological and Resource Modelling

11 SAMPLE PREPARATION, ANALYSES AND SECURITY
11.1 Sampling
Samples are prepared from NQ diameter drill cores (47.6mm core diameter). The sampling procedures described in this section reflect the current Standard Operational Procedures (SOP) in use by Lithium Ionic.
Sample intervals in the mineralized zones are defined based on a one-meter support. Mineralized samples must have a minimum length of 1.00m and a maximum length of 1.50m. In some specific situations, samples shorter than 1.00m can be generated. These situations are described in detail in the SOP.
Outside the mineralized domains, the sampling support is 1.50m, and samples can range from 1.00m to 3.00m.
The visual indicators for sample interval definition include lithological contacts, structures, and mineralization.
The sample collection and sample definition procedures adopted by Lithium Ionic are described below:
-
Drill core is brought in by the drilling contractor team, one or more times per shift, from the drill rig to a drill logging and sampling area.
-
The disposition and orientation of boxes are checked, and the depth lengths are marked.
-
Core boxes are photographed (three boxes per picture) and logged.
-
Sample intervals are marked with a pencil in the core box.
-
Before sampling, the drill core is marked by a line drawn along the core at high angles to the foliation to orient the saw cut. The left side of the core is selected as a sample. The remaining half of the core is retained for future reference.
-
Sample tags are attached to the core box at the end of each sample.
-
Sample bags are numbered before sampling.
-
Sample tags are inserted in the bags only after samples are bagged.
-
After the samples are tagged and bagged, they are weighted.
-
The core is cut lengthwise along the core axis. A Geologist defines the position of the cut, and a Geology Technician performs the cutting.
-
For weathered material, a spatula or a machete is used to split the sample into two subsamples along the drilling direction.
-
Fresh rock cores are cut in half using a diamond saw and flushed with water between cuts.

-
After bagging, the samples are weighted, and the weight is registered.
-
Batches are assembled and sent to the laboratory.
The standard batch size is 35 samples, consisting of 29 core samples and six quality control samples.
11.2 Sample Preparation, Security and Custody Chain of Custody
Samples are defined and marked on-site after logging and entering the data into the database. Cores are split in half using a diamond saw. Half of the core is retained in the core box, while the other half is stored in plastic bags, accompanied by a printed sample tag, and sent to the lab.
Drill core samples are prepared and analyzed by an independent commercial laboratory (SGS Geosol). The SGS Geosol facility is certified in ISO 9001, ISO 14001, and ISO 17025. The sample shipment is delivered to the SGS Geosol facility in Vespasiano, Minas Gerais, Brazil, via a parcel transport company. At all times, samples are in the custody and control of the Company’s representatives until delivery to the laboratory, where samples are held in a secure enclosure until processing. SGS Geosol sends a confirmation e-mail with details of samples received upon delivery. The chain of custody of the batches was carefully maintained from collection at the drill rig to delivery at the laboratory to prevent accidental contamination or mixing of samples and render active tampering as tricky as possible.
All samples received at SGS Geosol are inventoried and weighed before processing. Samples are dried at 105°C, crushed to 75% passing <3 mm sieve, homogenized, split (jones riffle splitter), and pulverized (250 to 300 g of sample) in a steel mill to 95% passing 150 mesh.
11.3 Sample Analysis
After the preparation, the core samples are analyzed by SGS Geosol. The chemical assays are performed using SGS’s analytical method ICP90A, a multi-element analysis using fusion by sodium peroxide (Na2O2) and an ICP-OES analysis. If lithium results are above 15000 ppm, SGS Geosol re-analyzes for lithium through the ICP90Q_Li method, similar to the ICP90A but with higher Detection Limits.
All chemical analysis conducted by SGS Geosol are reported to Lithium Ionic on PDF certificates, accompanied by an MS Excel digital file.
11.4 Density Measurements
The density SOP currently in use by Lithium Ionic states that density measurements should be taken for every geochemical sample generated. When the drill core quality does not allow for the density assay, this should be registered in the density sampling plan with a specified tag. The high frequency of the density sampling aims to acquire a statistically robust database.
Three samples should be taken for the geochemical samples with more heterogeneity: one on

the top of the sample, the other in the middle and one further in the base. Homogenous geochemical samples should generate only one density sample. Density samples must have a minimum length of 10 cm and a maximum of 25 cm. The density assay procedures do not include drying or sample sealing. Density is commonly measured in the unsampled half-cores, reflecting a faster and more dynamic drillhole data collection process. All density data is stored in a database. A summary of the procedures described in the density SOP is presented next:
-
Sample selection and registration in the density plan.
-
Weighing of the sample.
-
Weighing of the sample while submerged.
-
Density values are acquired from the following formula:
-
D = PA / (PA – PB).
-
D = Density.
-
PA = Sample weight (in the air).
-
PB = Sample weight (submerged in water).
The density assay procedures do not include drying or sample sealing with paraffin. Not implementing the mentioned procedures might be acceptable considering the deposit's climate and lithological characteristics.
For a more conclusive evaluation of the effect of those procedures on the density results, GE21 recommends duplicate density assays, using the SOP procedure in one sample and a procedure that includes drying and sealing in the other sample. For the sealed samples, the density formula to be used is:
Ds = Ps / [(Pp – Pj) – (Pp – Ps) * dp] Ds = Dry Density.
Ps =Dry sample weight (in the air).
Pp = Sealed sample weight (in the air).
Pj = Sealed sample weight (submerged in water). Dp = Paraffin density.
11.5 Quality Assurance and Quality Control (QA/QC)
The Quality Assurance and Quality Control program implemented was proposed by the independent company GE21. The sample batch composition includes 5 Quality Control Samples for every 30 regular samples. The Quality Control composition of the batches is described next:
-
Coarse (Preparation) and Fine (Analytical) Blanks: 6% of the batch, or two blanks per batch, one of each type.
-
Standards: 6% of the batch, or two standards per batch.
-
Crushed Duplicates: 3% of the batch, or 1 sample per batch.
-
Pulverized Duplicates: 3% of the batch, or 1 sample per batch.

==> picture [90 x 45] intentionally omitted <==
Additionally, one sample is selected for the Check Assay procedure for every sample batch, representing 3% of the batch. Check samples are chosen from the pulverized material of a regular sample reserved by the primary laboratory. These samples are sent to a secondary laboratory, ALS Vancouver, monthly. ALS Vancouver is ISO 17025 accredited.
The same control sample proportion criteria should be respected on Check Assay batches: 2 standards, two blanks, and two duplicates. Particle Size Analysis (PSA) is also performed on the Check Assay samples. Figure 11-1 presents the batch composition scheme for batches with mineralized samples or zones and unmineralized batches. Table 11-1 shows the proportion of Quality Control samples in the Lithium Ionic geochemical database.

11.5.1 Preparation Blank – Coarse Blank
Preparation blank samples are inserted in the sample batch before the physical preparation of the samples. This measure helps to track any contamination problems that might occur in the granulometric reduction or sample-splitting processes. Blank samples are inserted at the beginning of the possibly mineralized intervals, following the sequence:
-
Mineralized sample.
-
Analytical/Fine Blank.
-
Preparation/Coarse Blank.
-
If an unmineralized batch is assembled, blank samples must be inserted at the beginning of the batch.

11.5.2 Analytical Blank – Fine Blank
Analytical or Fine Blank samples are inserted in the analytical batches after the samples’ physical preparation. This type of blank sample is used to assess contamination problems that might occur in the sample digestion or sample fusion processes and to evaluate analytical equipment (in this case, ICP-OES) miscalibrations. Blank Samples are inserted at the beginning of the possibly mineralized intervals, following the sequence:
-
Mineralized sample.
-
Analytical/Fine blank.
-
Preparation/Coarse blank.
If an unmineralized batch is assembled, blank samples must be inserted at the beginning of the batch.
For its QA/QC Program, Lithium Ionic used three types of commercial Fine Blank controls: ITAKQF-15, ITAK-QF-16 and ITAK-QF-18. Only two in 279 control samples inserted have returned grades higher than the 5x Detection Limit threshold, indicating no systematic contamination or calibration problems in the final stages of the geochemical analysis.

11.5.3 Certified/Standard Reference Material – CRM/SRM
Certified or Standard Reference Materials are reference materials for which one or more parameters have been certified by a technically valid and recognized procedure. A certifying body has issued a Certificate or other accurate documentation. These materials are used as quality control samples to evaluate the accuracy of the analytical methods and procedures.
Lithium Ionic uses 4 CRMs/SRMs: ITAK – 1100, ITAK – 1101, OREAS 750 and OREAS 752. These Reference Materials evaluate high, medium, and low-grade assay results.
Medium-grade or high-grade Reference Materials are inserted at the beginning of the possible mineralized zones. The insertion can occur immediately or a few samples before the mineralized zone. The low-grade Materials are inserted at the end of the zone where the Geologist interprets mineralization. The insertion can be immediately after or a few samples after the mineralized zone. The order of the Reference Materials can be changed based on geological features or mineralization characteristics.
Figure 11-6 to Figure 11-9 present Lithium's CRM/SRM control charts. More than 80% of the samples are constrained within the 2x Standard Deviation limits.

11.5.4 Crushed Duplicates
Duplicates are used in the Quality Control program to evaluate the precision of geochemical analysis. Insertion of blind duplicates of crushed (75% passing in 3mm sieve) material is used to test the laboratory’s reproducibility and determine if the sample preparation process generates bias or imprecision in the results.
A total of 273 crushed duplicates were evaluated. Control charts for this control type show high correlations and good reproducibility, with over 90% of the samples falling below the 20% HARD limit. Figure 11-10 presents the control chart.

12.2 QP Opinion
No major issues were identified with the database. The QP’s opinion is that the practices and procedures used to generate the Lithium Ionic database are sufficient to support Mineral Resource estimation. Some observations that were recorded during visits as they relate to the generation, collection, control, and storage of exploration data on-site at Araçuaí-MG are:
-
The site visits included reviewing the QA/QC, field checks of the core shed, drilling in progress, review of density procedures, and discussions of the current geological interpretations with geologists of Lithium Ionic.
-
Drill hole collars have a physical identification marker. The markers comprise a concrete pad with a metal plate designating the drilling contractor, drill hole number, drilling area, orientation, coordinate location, start and end date drilled, and total depth. A PVC pipe protruding from the marker provides a physical record of the drill hole orientation.
-
All core boxes were labelled and adequately stored in a core shed house. Sample tags were present in the boxes, and it was possible to validate sample numbers and confirm the presence of mineralization in witness half-core samples from the mineralized zone.
-
The QP considered the Drill Hole Logging as standard industry practice logging procedures, which Lithium Ionic has standardized. They reviewed logging procedures for randomly selected drill cores and verified the completeness of the logs.
-
Lithium Ionic has its database software. Data storage procedures at Lithium Ionic are considered within standard industry practice. As part of the validation process, 12 holes were verified. Database validation was conducted with the Lithium Ionic staff according to standard validation procedures, including a review of collar locations, drill hole deviations and database check-assay review. QP found no inconsistencies in the database.
-
An extensive database of wet density information was collected during the exploration phase. Assessing density samples' moisture and porosity impact on bulk density measurements is strongly recommended.
-
The QP checked the Lithium Ionic procedures for sampling management, storage, logging, sample preparation, and assay. They are considered inside acceptance limits and in compliance with mineral industry practices.
-
Rock-type descriptions fit with the checked mineralization style. Lithium Ionic has demonstrated that it understands geology.

13 MINERAL PROCESSING AND METALLURGICAL TESTING
The underground mine ore body at Bandeira Project are spodumene-rich pegmatites, SRP type (cf. Pedrosa-Soares et al., 2023), characterized by being non-zoned to poorly zoned pegmatites, rich in spodumene crystals (average in size 5 to 30 cm) disseminated in a matrix composed of albite, quartz, perthitic microcline (i.e., potassium feldspar with exsolved albite lamellae), muscovite, and petalite, totaling over 90% volume, with subordinate amounts (up to 10% volume) of accessory and alteration minerals, such as lithium minerals (cookeite, montebrasite, triphylite, and zabuyelite), apatite, Nb-Sn-Ta and Fe-Mn oxides, graphite, and clay minerals (kaolinite and montmorillonite).
The technological characterization includes chemical and mineralogical analyses, physical tests for hardness determination, particle size distribution in crushing assays, abrasiveness level, and metallurgical tests to identify the ore's response when subjected to simulation of the industrial process of ore mineral concentration (in this case, spodumene).
13.1 Ore Mineralogical Characterization
The lithium minerals present in the pegmatites of the Bandeira Deposit have been routinely characterized through systematic logging of drilling cores. From core intervals selected samples are taken through the description of thin polished sections under an optical microscope. Those descriptions, macroscopic (log) and microscopic (thin sections), are accompanied by modal evaluation (in vol%) of spodumene versus matrix contents, and within the matrix, the quantities of minerals identified, particularly those that may significantly interfere with ore processing. As a result of these descriptions, the lithium minerals identified in the pegmatites of the Bandeira Deposit are listed in Table 13-1. In addition to the lithium minerals listed in Table 13-1, the spodumene ore from the Bandeira Deposit contains the following main gangue minerals (average modal values in vol%): albite, quartz, perthitic potassium feldspar and muscovite.
Other accessory minerals, besides those listed in Table 13-1, typically present in amounts less than 1% volume, include: apatite, beryl, cassiterite, columbite-tantalite (including Fe-columbite determined by SEM-EDS), and graphite.

The mineralogical characterization of the Bandeira ore was conducted using X-ray diffraction (XRD) analysis with a Bruker-AXS D8 Advance ECO instrument, utilizing CuKa radiation (40kV/25mA) with a Ni filter, a step size of 0.02º 2ϴ, and an accumulated counting time of 192 seconds per step with a position-sensitive linear detector of the silicon drift type, LynxEye XE, collected from 5 to 105º 2ϴ in θ-2θ geometry on the goniometer. Quantitative analysis was calculated using the total multiphase spectrum refinement method (Rietveld method), by fundamental parameters, with Bruker-AXS Diffrac. Topas software, version 6.
The average mineralogical analysis for the 07 (seven) ore variability is presented in Table 13-2. The ore variability results are presented in the item 13.4 of this chapter.

13.3 Metallurgical Testing
Preliminary metallurgical tests using Heavy Liquid Separation (HLS) were conducted by SGS Geosol. Ore sorting tests were carried out by TOMRA in Germany and at Steinert in Brazil. Ore variability test work campaign was develop in different research center and laboratories like SGS Geosol, SGS Chile, CETEM and Metso Outotec.
13.3.1 Preliminary HLS Test at SGS Geosol
Samples from drill holes ITDD-22-001, 002, and 007 were combined to generate a composite and sent to SGS Geosol. This sample was prepared according to the procedure shown in Figure 13-1, to proceed with HLS test. The objective of this test is to evaluate the performance of dense media separation in obtaining lithium concentrate for the Bandeira Project, according to market specifications, by varying the particle size distribution and density of the dense media.
20 kg sample was dried and crushed in a jaw crusher with openings of 31.5, 25.4, and 12.7 mm to obtain material 100% passing 12.7 mm. After this, particle size analysis was conducted using a sequence of sieves of 12.7, 6.3, 1.7, and 0.5 mm. For each size fraction, a representative sample was collected for chemical analysis. HLS tests were conducted at densities of 3.0, 2.9, 2.8, and 2.7 g/cm³, for the size fractions -12.7+6.3 mm, -6.3+1.7 mm, and -1.7+0.5 mm.

The particle size distribution of the material passing 100% through 12.7 mm is presented in Figure 13-2. It is worth noting that approximately 12% of the mass does not have suitable particle size for the dense media separation stage, meaning it is smaller than 0.5 mm. The Bandeira Project considers a future study of concentration of the fine fraction (-0,5 mm) using gravity equipment or flotation.
Chemical analysis identified the predominant presence of aluminum oxide (17.10%), potassium oxide (2.39%), and lithium oxide (1.63%), as shown in Figure 13-3. The presence of aluminum can be mainly attributed to albite, K-feldspar, and spodumene. Potassium is predominantly present in K-feldspar, while lithium is in spodumene. Regarding iron oxide, the main contaminant for market specifications, the concentration in the ore is 0.23%. The mineral origin of iron is mainly schists (biotite). Besides the presence of iron, another point of concern regarding the schists is its density, which can vary between 2.40 and 3.05 g/cm³, similar to the cut-off density used for dense media separation commonly employed for spodumene concentration, considering the density of the mineral of interest varies between 3.15 and 3.20 g/cm³ (PEIXOTO, et al., 2016).

The Heavy Liquid Separation tests were conducted for each particle size fraction; (i) -12.7 +6.3 mm, (ii) -6.3 +1.7 mm and (iii) -1.7 +0.5 mm, using organic liquid to evaluate the optimal density to achieve the market specification of lithium concentrate, i.e., a minimum of 5.5% Li2O and a maximum of 1% Fe2O3. The densities evaluated were (i) 2.7 g/cm³, (ii) 2.8 g/cm³, (iii) 2.9 g/cm³, and (iv) 3.0 g/cm³, for which solution with different proportions of methylene iodide (density: 3.29 g/cm³) and acetone (density: 0.79 g/cm³) were prepared.
Tests for the particle size fractions of -12.7 +6.3 mm and -6.3 +1.7 mm were conducted in beakers, while the test for the finer particle size fraction (-1.7 +0.5 mm) was carried out using a separating funnel. The test involves mixing the ore and the dense media solution in the reactor (beaker or separating funnel) and waiting for separation. Afterward, the sunken material, the dense media, and the floated material are collected separately. Densities were evaluated sequentially according to Figure 13-4, and for each stage, chemical composition and mass partition were assessed.

From the results presented in Figure 13-5, the cumulative content of Li2O and Fe2O3 per each density for the three particle size fractions evaluated can be observed. This value was calculated based on the individual content of each sample and the mass partition.
It can be noted that the cut-off density increases with particle size. For finer particles, it is possible to obtain a concentrate meeting the specification using a cut-off density of 2.7 g/cm3. However, for the intermediate particle size range, the cut-off should be performed at 2.8g/cm3, and for the coarser material, at 2.9 g/cm3.
It is observed that the Li2O content in the floated material for the coarser particles is approximately three times higher than the content in the floated material for the finer particles. This indicates lower liberation of spodumene in the coarser particle size range.
Regarding iron oxide, it is found that the maximum content limit was met for all tested densities.

The recovery results by particle size range and the overall recovery of the HLS are presented in Figure 13-6, along with the Li2O content in the concentrate. For the particle size range -12.7 +6.3 mm, the cut density was 2.84 g/cm³, representing a recovery of 70.5%. These values were obtained by interpolation. For the -6.3 +0.5 mm range, the density was 2.71 g/cm³ and the recovery was 90.1%. However, considering the loss of fines, i.e., fractions smaller than 0.5 mm, which represent 12% of the mass and 11% of the lithium, the HLS recovery was 74.8%.

13.3.2 Vendors Tests
Some test work has been conducted by vendors like:
-
Ore Sorter
-
Crushing Work Index (CWI)
-
Crushing equipment to determine BWI (Bond Work Index), ore abrasiveness, equipment working capacity.
13.3.2.1 Ore Sorter at TOMRA
A composite sample from 6 drill holes (ITDD-22-013, 015, 029, 032, 035, and 036) with lithium oxide (Li2O) content ranging from 1.31 to 1.52% was sent to TOMRA in Germany to evaluate the applicability of the Ore Sorter in the pre-concentration stage. The material was crushed to achieve 100% passing at 31.5 mm and separated into 3 particle size ranges (-31.5 +19.1 mm; -19.1 +9.5 mm; and -9.5 mm). Tests were conducted on two particle size ranges, -31.5 +19.1mm and -19.1 +9.5 mm, while the -9.5 mm material was weighed, and its content determined to complete the metallurgical balance of the test. A preliminary analysis on the sample indicated the use of X-ray Transmission (XRT) sensor for conducting the test.
The X-ray Transmission sensor is related to the atomic density of the material, where higher transmitted X-ray intensity corresponds to lower absorption and lower atomic density. Electromagnetic radiation, between 90 and 200 keV, is directed onto the sample, and the transmitted radiation is detected pixel by pixel, converted into an electrical signal to generate a grayscale image. Hence, a lighter shade indicates lower absorption, thus lower atomic density. To distinguish thickness and atomic density, two sensors are utilized, acquiring different energy bands (VERAS, 2018; WOTRUBA & HARBECK, 2012).
The tests were conducted using the principle of cascade classification, as depicted in Figure 13-7. The sample was fed via a vibratory feeder onto a conveyor belt and analyzed by the Duoline X- ray sensor. The initial configuration of the equipment was programmed to eliminate all particles with at least 30% of high atomic density pixels. Subsequently, the previously classified low-density material was reclassified, eliminating all particles with at least 80% of high and medium atomic

density pixels. Lastly, the particles not ejected in the intermediate stage underwent further classification, where particles with at least 50% of high and medium density pixels were eliminated, while those with low atomic density pixels were retained, constituting the ore sorter concentrate.

The results obtained are presented in Table 13-4 and Table 13-5 for the particle size ranges of - 31.5 +19.1 mm and -19.1 +9.5 mm, respectively. The fine fraction (-9.5 mm) accounted for 16.9% of the mass, which will be sent to the dense medium concentration stage. From the results, it is possible to observe that with the decrease in the ore sorter's average atomic density cut-off, the concentrate grade increases, and the metallurgical recovery decreases for both particle size ranges. Therefore, configuration 2 was selected as the most promising, as it was possible to enrich the dense medium feed grade by 25 to 26%, recovering 91 to 94% of the lithium.

Subsequently, tests were conducted at TOMRA to evaluate the effect of dilution with shale on the equipment's performance. For this purpose, two drill holes, ITDD-22-054 and ITDD-22-098, with 10% dilution at the intersection with the pegmatite, were selected. The samples were crushed to achieve 100% passing at 31.5 mm and separated into 4 particle size ranges (-31.5 +19.1 mm; - 19.1 +9.5 mm; -9.5 mm +0.85 mm; and -0.85 mm). Tests were conducted for two particle size ranges, -31.5 +19.1 mm and -19.1 +9.5 mm, while the material from the other size ranges was weighed, and its content determined to complete the metallurgical balance.

The tests were conducted using the same cascade classification principle applied previously, as shown in Figure 13-7. Table 13-6 and Table 13-7 present the results of the ore sorter test for the particle size range -19.1 +9.5 mm for the two drill holes. It is possible to observe that the results obtained for both samples were similar and indicate that configuration 1 is the most suitable. This is because, in this setup, enrichment between 19 and 20% was achieved with 94-96% recovery.

The results for the particle size range -31.5 +19.1 mm are presented in Table 13-8 and
Table 13-9 for drill holes ITDD-22-054 and ITDD-22-098, respectively. There were discrepancies in the results between the two samples for the coarse particle size range, despite the difference in Li2O content in the test feed being less than 5% (1.31% for ITDD-22-054 and 1.26% for ITDD22-098). Since no significant variation was observed in the results of the tests with and without dilution for the particle size range of -19.1 +9.5 mm, and no relevant effect of particle size on the undiluted test was observed, the result of drill hole ITDD-22-054 for coarse particle size was not considered in the ore sorter application analysis, as it differs from the other results obtained. Therefore, the second configuration is indicated as the most interesting, as it achieved a recovery of almost 93% of lithium, with an enrichment of 17%.

13.3.2.2 SGS Chile – CWI (Crushability Work Index)
The Bond Low Energy Impact test was conducted at SGS Chile to determine the Crushing Work Index (CWi), a factor indicating the power required for crushing. For the assay, 20 pieces cut to a thickness of 51 mm were sent. Each specimen was subjected to the impact of two hammers mounted on a pendulum. The test was repeated with an increase in the pendulum angle, thus increasing the impact, until the sample fractured. Cwi results varies from 4.1kWh/t to 10.2 kWh/t. The average result was 7.0 kWh/t, characterizing medium crushability work index. Table 13-10 and Table 13-11 shows the results obtained for this test.

13.3.3 Ore Variability
A variability study was conducted to understand the geological and metallurgical ore variability. First, eight drill holes without schist was selected to evaluate the HLS performance for different samples. Then, fifteen new samples from eleven drill holes were selected to evaluate the ore sorter and HLS performance in different area and depth with schist dilution.
13.3.3.1 Undiluted Samples – HLS tests
Figure 13-8 indicates the location of the eight drill holes selected, those has maximum 100m depth and minimum 5m interception, except ITDD-23-134T only used to Bond Low Energy Impact Test. A total of 906 kg was sent to SGS Geosol to be prepared, which includes crushing, screening, and sampling. The HLS was performed in duplicate at two particle size ranges -12.7 +6.3mm and -6.3 +0.85mm for three densities 2.8 g/cm³, 2.7 g/cm³ and 2.4 g/cm³, simulating a rougher-scavenger circuit and a polishing step for petalite recovery.

HLS rougher-scavenger results are presented in Table 13-13 and Table 13-14 for each particle size range. The 2.4 g/cm³ step did not presented significative mass for all samples, which indicates minor presence of petalite. In general, rougher concentrate presented Li2O grade above 5.5% with average global recovery of 84% for the coarse and 89% for the fine fraction.
Composite samples were tested to evaluate the combined behavior of the cluster. The composite results fit to the polynomial adjustment as shown in Figure 13-9 and Figure 13-10. The metallurgical recovery polynomial adjustment adherence with the composite results is shown in

According to Figure 13-12 and Figure 13-13 spodumene is mainly in the concentrate for both particle size distribution. Montebrasite distribution is presented in Figure 13-14 and Figure 13-15 and it is reported mainly in the tailing fraction. The same behavior happens to petalite distribution as shown in Figure 13-16 and Figure 13-17.

13.3.3.2 Diluted Samples – Ore Sorter & HLS Tests
Figure 13-20 indicates the location of the 11 new drill holes (phase 2 in blue) among those two drill holes (ITDD-23-065 and ITDD-23-073) were selected three in different depths, to evaluate the metallurgical response over the LOM. For these samples, were performed ore sorter tests and HLS.
Ore sorter tests were done in two particle size range -31.5+19.1 mm and -19.1+7.5 mm. Then both concentrates were combined jointly together with the fraction size below 7.5 mm, that did not pass through ore sorter concentration. These composite samples were used to perform HLS tests in two particle size range -12.7+6.35 mm and -6.35+0.5 mm in three densities (2.8 g/cm³, 2.7 g/cm³ and 2.45 g/cm³).
Ore sorter results are presented in Figure 13-21 below for lithium and iron. In general, average lithium recovery was 93.6% and 92.6% respectively.

Coarse and fine ore sorter concentrate were combined with fine fraction -7.5+0.5 mm to perform HLS tests. The particle size in HLS was -12.7+6.35 mm and -6.35+0.5 mm. A 3-stage circuit was simulated by HLS test in 2.80 g/cm³, 2.70 g/cm³ and 2.45 g/cm³. Table 13-15,
Table 13-16 and
Table 13-17 present HLS results. Rougher average metallurgical recovery was 77.8% with 22.1% of mass recovery. Scavenger step may increase the metallurgical recovery up to 86.1% with 34.0%. The step in 2.45 g/cm³ to may increase average metallurgical recovery up to 88.2% and mass recovery up to 2.1%. Figure 13-22 indicates the polishing effect.

13.3.4 Pilot Plant – Ore Sorter (Steinert) & DMS (SGS Geosol)
After completing the variability study from 7(seven) drill holes, the reserved samples were tested by ore sorter equipment and DMS pilot plant, as shown in Figure 13-23. Besides it, a composite sample was selected to perform HLS test by size to evaluate liberation.
Ore sorter tests were performed as describe in Figure 13-23. For the coarse material (-25.4+6.35 mm) each sample had mass around 7 kg. Two samples were tested individually, and the others five samples were composed in one to improve test representative. The fine material (-12.7+6.35 mm) was tested individually.

Ore sorter results are shown in Table 13-18. Lithium recovery ranged from 88.1 to 96.1% with average mass loss of 18.1% and enrichment factor of 1.12. Mass recovery to the concentrate should be lower to increase lithium recovery, once were used undiluted samples. New tests using diluted samples were completed to validate the ore sorter results. Regarding iron and potassium, tailings enrichment factor was 1.37 and 2.34, respectively, with good results of discharging schist and feldspar to tailings.
The liberation particle size was evaluated by performing HLS test in 7 particle size range, from top size of 19.1 mm to 0.5 mm. To avoid sampling error all the mass retained in 15.9 mm sieve was used in the coarser HLS test. For HLS test with particle size below 15.9 mm up to 1.7 mm, 500 g were sampled from the total mass retained in each sieve and for the finer samples 150 g

were used. This procedure was recommended by SGS Geosol as their best practice.
The tests used two densities, 2.8 g/cm³ and 2.7 g/cm³, simulating rougher and scavenger stages. The results for each particle size range are shown in Table 13-19. In general, the results indicate that the recovery tends to decrease as the particle size increases. On the other hand, the Li2O grade decreases as the particle size increases.
Table 13-20 presented the grade and recovery results accumulated by mass distribution. Figure 13-24 shows the results of each HLS size particle range.

The tests at the DMS pilot plant were conducted using composite samples from the seven drill holes of the variability tests. These samples underwent testing in an Ore Sorter at Steinert for the removal of schist and feldspar, followed by particle size adjustment to meet the specification of the DMS pilot plant. The DMS tests were conducted in two size fractions. The coarser fraction was prepared at -9.5 mm +3.55 mm, and the finer fraction was prepared at -3.55 mm +0.5 mm. Below is the list of drill holes from which the samples were composed:

Figure 13-25 presents a flowchart reproducing the unit operations in the SGS Geosol DMS pilot plant. 25 DMS pilot plant tests were performed (21 Rougher and 4 Scavenger) to obtain supporting information for the Bandeira process development.
The circuit includes a hopper, manually fed with ore, connected to a vibrating feeder responsible for feeding this ore into the static mixer. The solid dense media (Iron Silicon) is fed directly into the agitated tank. This dense media undergoes a dilution process and subsequent pulp density adjustment by injecting water into the tank or the first section of the screen's chute.
The prepared dense media with the appropriate density feeds by gravity into the chute of the first section of the screen. From this point, the dense media is pumped through a demagnetizing coil and a flow divider with manual valves. The flow divider directs part of the dense media to the screen, and the rest recirculates to the agitated tank. The screen's function is to protect the system and retain undesirable or inadequately sized materials. The screen underflow feeds the static mixer, positioned just above the DMS cyclone. This static mixer promotes the mixing of the ore from the vibrating feeder and the dense media from the screen underflow. The gravity feed of the DMS cyclone establishes a cyclone feed pressure based on the height of the liquid column relative to the vertical distance between the DMS cyclone feed flange and the pulp level in the static mixer.
The DMS cyclone, positioned at a 20-degree incline relative to its centerline, separates the mixture by density, partitioning it into sink (underflow) and float (overflow). In this process, the concentrate is directed to the sink flow, and the reject is directed to the float flow. The dewatering screen has a partition into two parallel sections and two underflow chutes. Each chute receives drainage from half of the parallel sections' area. The cyclone sink is directed to the first section of the screen, and the float is directed to the second section. In the first screen chute, the dense media concentrate is drained. From the second chute, wash water is injected to remove residual dense media and drain this diluted flow. The diluted dense media is then pumped to the magnetic separator, which retains Iron Silicon particles and removes excess water, concentrating the dense media mixture. The concentrated dense media is then recirculated to the agitated tank, while the water is discarded. The DMS concentrate is equivalent to the oversize from the first section of the dewatering screen, and the DMS reject is equivalent to the oversize from the second section of the screen.
To conduct the scavenger stage test, this process is repeated by refeeding the reject obtained in the rougher stage.

The results of the pilot tests were presented in graphical representations to define trend lines and points of coherence for a comprehensive analysis of the results.
The initial rougher tests for the coarse fraction were discarded as they were part of the pilot plant's calibration period. The results of the tests considered for the rougher stage indicated the following trend curve (Metallurgical Recovery x Li2O Grade in Concentrate) for the -9.5 mm +3.35 mm fraction is presented in Figure 13-26.

The analysis of these data converges to achieve a metallurgical recovery of about 75.42% to obtain a concentrate with a Li2O grade of 5.50% in the rougher stage, considering the combination of the two tested size fractions. To achieve this metallurgical recovery, the results of tests 16 and 17 were adopted as references. Since both produced concentrates with Li2O grades higher than 5.50%, it was necessary to recalculate the metallurgical recoveries. The Figure 13-29 presents the results of tests 16 and 17, as well as the adjusted metallurgical recoveries to obtain a 5.50% concentrate and an overall rougher stage metallurgical recovery of 75.42%.

of the project indicate the mass distribution as shown in the Figure 13-30:

Thus, the analysis of the test results suggests that the rougher stage of the DMS circuit can establish an overall metallurgical recovery of 63.15%.
13.3.4.2 DMS Scavenger Stage Potential Gains – Global Recovery
For the Scavenger stage, the results of the same tests adopted as references in the rougher stage (16 and 17) were considered. The Figure 13-31 presents the metallurgical recoveries and grades of the Scavenger concentrates.

Source: Lithium Ionic 2024
From the Scavenger concentrate, there is a possibility of increasing the overall metallurgical recovery. To achieve this, this material needs to undergo a new crushing stage to increase ore liberation, and then be re-fed into the DMS circuit. This reprocessing was not tested in the pilot plant. However, considering similar operations and the Rougher/Scavenger test work results, it is estimated that a potential gain of up to 5.71% in the overall plant metallurgical recovery could be achieved through this reprocessing. Thus, it would be possible to obtain an overall metallurgical recovery of 68.86%.

14 MINERAL RESOURCE ESTIMATES
GE21 conducted comprehensive 3D geological modelling, statistical and geostatistical studies, and grade estimation for the Lithium Ionic Bandeira Property. This estimation considered various factors, such as the quantity and distribution of available data, interpreted controls on mineralization, mineralization style, and the quality of the sampling data.
The geological modelling and estimation processes were executed utilizing Leapfrog 2023.2.1 software. The UTM Projection – Zone 23 South in SIRGAS 2000 Datum was adopted as the reference coordinate system for the database in this project.
14.1 Drilling Database
The database underwent a comprehensive visual validation, considering the interrelation of tables, identifying gaps and overlaps, and ensuring the inclusion of crucial information. Using Leapfrog Geo software, GE21 also conducted validation checks on the Collar, Survey, Assay, and Lithology tables. This stage of the work did not reveal any significant inconsistencies, as these had already been verified during the Data Verification stage.
Mineral Resource estimates were based on data derived from drill hole and trench databases, incorporating lithology logs and assay results from HQ drill core samples. The topographic surface bounds the extent of these estimates. Figure 14-1 illustrates the spatial distribution of the utilized drill holes.
The original dataset provided by Lithium Ionic encompassed data from 267 surface diamond drill holes (totalling 54,116 meters) and 31 trench channels (2,245 meters) executed by Lithium Ionic data available from 2022 until March 5[th] , 2024.
Until March 5[th] , 2024, the Bandeira database contains 8,693 assay intervals covering 8,168 meters, comprising 105 assays from trenches totalling 100 meters and 8,588 assay intervals from drill holes totalling 8,068 meters.
The assay table includes data for various elements, including Li (ppm), Li2O (%), Al (%), As (ppm), B (%), Ba (ppm), Be (ppm), Ca (%), Cd (ppm), Co (ppm), Cr (ppm), Cu (ppm), Fe (%), K (%), La (ppm), Mg (%), Mn (ppm), Mo (ppm), Nb (ppm), Ni (ppm), P (%), Pb (ppm), Sb (ppm), Sc (ppm), Sn (ppm), Sr (ppm), Ta (ppm), Ti (%), V (ppm), W (ppm), Y (ppm), and Zn (ppm). Following a thorough review of the database, the Li2O (%) data was extracted explicitly for subsequent statistical analysis, block modelling, and resource estimation.

14.2 Geological Modeling
Lithium Ionic undertook a geological interpretation encompassing all documented pegmatite intervals within the Bandeira deposits. Initially, cross-sectional interpretations were crafted utilizing traditional manual techniques and advanced cartographic software platforms such as QGIS, ArcGIS, and Leapfrog. These initial steps laid the groundwork for a robust modelling process.
The Lithium Ionic team interpreted a set of grade shell sections, with an envelope delimiting a zone with a cut-off grade of 0.3% Li2O (%) (Figure 14-2 and Figure 14-3). The resulting interpretations were developed into a series of implicit 3D models aligned with two prevailing strike directions: 235° and 140° (Figure 14-4 and Figure 14-5).
Lithium Ionic also conducted weathering modelling, basing the analysis on the descriptions provided in the logs (Figure 14-6).
The Qualified Person thinks the geological interpretations and modelling suit a Mineral Resource Estimation study. Quality assurance procedures follow the industry’s best practices, and the model honours the mineralized pegmatite intervals and has adequate continuity of the modelled bodies.

14.3.3 Variographic Analysis
The structural analysis of the domains was conducted to determine the variographic parameters, which are essential for determining the spatial continuity model of the grade variables and for the grade estimate.
Variograms were generated explicitly for Li2O% within the spodumene veins suite. This approach considered the geological similarity among them, enhancing the robustness of the variograms. Two distinct sets of veins were considered:
-
NW Veins Suite.
-
SE Veins Suite.
The variographic analysis was executed using Leapfrog Edge software. Figure 14-9 to Figure 14-12 show the variograms for the Li2O% variable for each set of vein domains. Additionally, Table 14-2 presents the variographic parameters obtained from all conducted analyses. These parameters were applied in the process of grade estimation.

14.5 Grade Estimation
The Ordinary Kriging (OK) was carried out in the Leapfrog Edge software and was used on the Li2O (%) variable estimation based on the structural analysis results described in this work.
Each mineralized vein was estimated independently, using a hard boundary strategy to ensure that samples from one domain did not influence neighbouring domains. The variograms were initially modelled considering the structural continuity across the entire set of domains, followed by an adjustment for honouring the specific behaviour for each domain. Table 14-5 shows the main parameters of the Kriging strategy applied in the grade estimation.

Maximum number of samples per Drill = 2.
14.6 Estimation Validation
The QP carried out the validation of the estimate through visual verification and by the Global and Local bias verification. Global and Local bias checks used The Nearest Neighbour as the comparison estimate. NN-Checks plots, Figure 14-13 and Figure 14-14 show the results for global bias analysis of the estimated Li2O% and density variables. It allowed verification of the expected estimation smoothing by Ordinary Kriging within the acceptance limits. The comparison showed that Ordinary Kriging globally respected the average grades, and the global bias in the estimated grades is within the limits of acceptance.
The local bias assessment by the Swath-Plot method aims to analyze the occurrence of local bias by comparing the average grades for the model through Ordinary Kriging and the Nearest Neighbour method in swath coordinates intervals graphs along the X, Y, and Z axes. Figure 14-15 and Figure 14-16 show the validation results of the Li2O% and Density swath plots.
The results from the grade estimate validation by Ordinary Kriging show that the smoothing effect or local and global bias are inside acceptance limits for mineral resource estimation.

14.7 Density
The density (g/cm³) in the spodumene pegmatites was estimated using Inverse Distance Weighting (IDW). How parameters were utilized for exponent 2, with minimum samples one and maximum samples 28.
The schists density was defined as the mean of the 4,830 samples from the Lithium Ionic database. The weathered zone doesn’t have measurements, and GE21 has adopted the value 1.8 g/cm³ for this domain, a common value used by other companies in the Jequitinhonha Valley region. GE21 recommends that additional density tests be carried out in weathered zones.
Table 14-6 shows the average IDW densities of each estimated pegmatite domain and the adopted densities of the host rocks.

14.8 Classification of Mineral Resources
The Mineral Resource was classified per CIM Standards and CIM Guidelines, utilizing geostatistical and classical methods and economically and mining-appropriate parameters relevant to the deposit type.
The Resource definitions by CIM are transcribed below:
-
A Mineral Resource is a concentration or occurrence of diamonds, a natural solid inorganic material or natural fossilized solid organic material, including base and precious metals, coal and industrial minerals in the earth’s crust or the earth's crust in such form and quantity and of such grade or quality that allows reasonable prospects of economic extraction. The location, quantity, level, geological characteristics, and continuity of a Mineral Resource are known, estimated, or interpreted from specific geological evidence and knowledge.
-
An “Inferred Mineral Resource” is that part of a Mineral Resource for which the quantity and level or quality can be estimated based on geological evidence and limited sampling and reasonably presumed but not verified geological and grade continuity. The estimation is based on limited information and sampling collected using appropriate techniques from locations such as outcrops, trenches, wells, and drill holes.
-
An “Indicated Mineral Resource” is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters to support mine planning and assessment of the deposit’s economic viability. The estimation is based on thorough and reliable exploration and testing information gathered using appropriate techniques from locations such as outcrops, trenches, wells, works, and drill holes spaced far enough apart for geological and level continuity to be reasonably assumed.
-
A “Measured Mineral Resource” is that part of a Mineral Resource for which quantity, level or quality, densities, shape, and physical characteristics are so well established that they can be estimated with sufficient confidence to allow the appropriate application of technical and economic parameters, to support production planning and assessment of the deposit’s economic viability. The estimation is based on thorough and reliable exploration, sampling, and analysis of information gathered using appropriate techniques from locations such as outcrops, trenches, wells, works, and drill holes spaced far enough apart to confirm geological and level continuity.
The classification boundaries made by GE21 for the Measured, Indicated, and Inferred categories were established through an approach that considered a comprehensive set of factors.
These factors included the sampling procedure analysis, the sample grid spacing, the survey methodology, and the quality of assay data.

==> picture [90 x 45] intentionally omitted <==
Additionally, drilling spacing and the progressive expansion of the search radius during grade estimation stages were also considered, as well as the average anisotropic distance of the samples and the continuity of pegmatite mineralization.
This multi-faceted approach ensured the robustness and accuracy of the classification process.
-
The Measured Mineral Resource classification referenced the 50 meters of the Average Euclidean distance to sample (AvgD) used in ordinary kriging estimation with a minimum of seven composites in at least three different drill holes.
-
The Indicated Mineral Resource classification referenced the 100 meters of the Average Euclidean distance to sample (AvgD) used in ordinary kriging with a minimum of seven composites in at least three different drill holes.
-
The Inferred Mineral Resource classification is all remaining estimated blocks.
-
The total mineral resources were limited to the boundaries of the mining rights.
The resource classification was supported by a grade shell representing the underground mining appliance (Reasonable Prospect for Eventual Economic Extraction – RPEEE), performed through a restricted wireframe based on a grade shell elaborated considering a cut-off of 0.5% Li2O. this value is commonly adopted for SRP-type pegmatites in the Lithium Valley province.
The Bandeira Mineral Resources Estimates results are shown in Table 14-7, Figure 14-17 and Figure 14-18.

23 ADJACENT PROPERTIES
The Araçuaí Pegmatitic District, situated in the northeastern sector of Brazil's Eastern Pegmatitic Province, encompasses the region bounded by Salinas, Araçuaí, and Capelinha to the west, and Itinga and Caraí to the east. In this district, Brazil's is a lithium producer, including lithium-bearing pegmatites, gemological pegmatites, and pegmatites that produce ceramic minerals and ornamental rocks. Many of these have been exploited by mineral exploration and mining companies, as well as by artisanal miners, for over a century.
The lithium-bearing pegmatites in the Araçuaí Pegmatitic District include complex zoned bodies with highly diverse mineralogy type, as well as simply to complexly zoned pegmatites rich in disseminated spodumene within a quartz-feldspar matrix that is rich in albite and relatively poor in accessory minerals. Current lithium exploration focuses on spodumene, which typically makes up deposits that can exhibit ore mass volumes of 5 to 30 million tons, with economic grades of lithium oxide.
The Araçuaí Pegmatitic District, particularly the Itinga Pegmatitic Field, is of extreme importance for prospecting projects, considering its production history and its geological and metallogenetic characteristics in this district, in terms of history and prospects for spodumene production, are the Brazilian Lithium Company (CBL) and the Sigma Lithium Corporation (successor to Arqueana de Minérios e Metais Ltda.).
The Bandeira lithium ore deposit, registered under ANM 832439/2009, is located adjacent to the mineralized areas of spodumene-bearing pegmatites, which include the Cachoeira deposits of the Companhia Brasileira de Lítio (CBL) and the Barreiro, Murial, and Lavra do Meio deposits of Sigma Lithium Corporation.
Figure 23-1 shows the locations of the mineral rights of CBL and Sigma Lithium surrounding the mining right 832.439/2009.

25 INTERPRETATION AND CONCLUSIONS
Mineral Resources were estimated and limited to the areas outlined using the Mining Rights polygonal that comprise the Bandeira Property and the Reasonable Prospect for Eventual Economic Extraction - RPEEE.
The original dataset provided by Lithium Ionic encompassed data from 267 surface diamond drill holes (totalling 54,116 meters) executed by Lithium Ionic data available from 2022 until March 5[th] , 2024. This Bandeira database contains 8,693 assay intervals covering 8,168 meters.
A set of solid-grade shells for estimation domains was created using a 0.3% Li2O (%) threshold. These interpretations were then transformed into a series of implicit 3D models, aligned with the dominant strike directions of 235° and 140°. Additionally, weathering modelling was performed, considering the information provided in the logs. The model was built from implicit modelling using the Leapfrog 2023.2 software.
The Ordinary Kriging (OK) estimation method was used on the Li2O% and Density variables based on the structural analysis results.
The mathematical/geostatistical criterion for classifying the resource was based on:
-
The Measured Mineral Resource classification had as a reference the 50 meters of the Average Euclidean distance to sample (AvgD) used in ordinary kriging estimation with a minimum of five composites in at least three different drill holes.
-
The Indicated Mineral Resource classification had as a reference the 100 meters of the Average Euclidean distance to sample (AvgD) used in ordinary kriging with a minimum of five composites in at least three different drill holes.
-
The Inferred Mineral Resource classification is all remaining estimated blocks.
The Bandeira Mineral Resources are summarized in Table 25-1.

26 RECOMMENDATIONS
GE21 proposes the following recommendations for the continuous improvement of the Mineral Resource estimate:
-
A 50x50m infill drilling program in the domain of the indicated resource classification that will focus on resource delineation improvement.
-
A 100x100m infill drilling program in the domain of the inferred resource classification that will focus on resource delineation improvement.
-
A density campaign to measure the density of drill hole cores by drying the samples in an oven, as well as waterproofing them. Compare the results with the methodology used in the current project procedure to check whether there is a bias in the results.
-
Conduct an on-site density survey in the weathered zone.
-
An updated mineral resource assessment is currently underway through the ongoing infill drilling program.
-
Detail Geotechnical analysis, including a geotechnical-oriented diamond drilling campaign and logging, including sampling collecting for tensile, compressive and shear strength tests.
-
Perform supplementary geotechnical investigations of planned infrastructure sites including at waste pile areas; supplementary geochemical tests (ARD); large-scale waste rock and tailings co-disposal stockpile field test.
-
To implement the hydrological and hydrogeological studies for the project's next phases.
