Lithium Ionic Reports Updated Mineral Resource Estimate at its Bandeira Lithium
Project, Minas Gerais, Brazil; Significantly Increases Global Mineral Resources in
the Lithium Valley
TORONTO, ON, May 6, 2025 - Lithium Ionic Corp. (TSXV: LTH; OTCQX: LTHCF; FSE: H3N)
(“Lithium Ionic” or the “Company”) is pleased to announce an updated mineral resource estimate
(“MRE”) for its 100% -owned Bandeira Lithium Project (“Bandeira” or the “Project”) located in
Minas Gerais, Brazil. Bandeira is the Company’s flagship property, located in Brazil’s “Lithium
Valley”, a rapidly emerging hard rock lithium district renowned for its significant concentration of
lithium-bearing pegmatites.
Prepared in accordance with National Instrument 43 -101 (“NI 43 -101”) by independent
consultants, GE21 Consultoria Mineral Ltda. (“GE21”), the updated MRE reflects continued
growth and resource conversion across the deposit, underscoring the scale, geological continuity,
and long-life potential of Bandeira as it advances toward development.
Bandeira Project - Mineral Resource Estimate Highlights
Measured and Indicated (“M&I”) MRE of 27.27 million tonnes (“Mt”) grading 1.34% Li ₂O,
containing 901,059 tonnes of lithium carbonate equivalent (“LCE”) ; with an additional
Inferred MRE of 18.55Mt grading 1.34% Li₂O, or 615,432 tonnes of LCE (see Table 1).
M&I growth represents a 30% increase in tonnage compared to the MRE used in the
Company’s Feasibility Study announced on May 29, 2024, and a 15% increase compared
to the MRE announced on April 12, 2024.
The updated MRE is based on 297 drill holes (60,301 metres), drilled between April 2022
and September 2024.
The MRE maintains consistent grade while expanding tonnage, reflecting strong continuity
and growth potential.
The updated Bandeira MRE increases the consolidated, global mineral resources to 36.76
Mt grading 1.31% Li₂O in the M&I category, in addition to 31.87 Mt grading 1.19% Li₂O in
the Inferred category (see Figure 1).
The Company plans to integrate the new MRE into an updated Feasibility Study, expected
in H2 2025.
*See press release dated January 14, 2025, for details related to the Baixa Grande MRE (effective date of December
2, 2024; QP: Leonardo Soares, P.Geo., M.Sc., of GE21), and the NI 43-101 compliant technical reports related to the
Outro Lado deposit titled “Mineral Resource Estimate for Lithium Ionic, Itinga Project” (effective date of June 24,
2023; authored by Maxime Dupéré, B. Sc., P.Geo. and Faisal Sayeed, B. Sc., P.Geo).
Blake Hylands, P.Geo., CEO of Lithium Ionic, comm ented, “Bandeira continues to grow
substantially while maintaining consistent grade, further validating its robustness and scal e
potential. This updated resource supports our mine planning efforts and will be an important input
as we work through detailed engineering and evaluate future production scalability.”
Carlos Costa, P.Geo., Lithium Ionic’s VP of Exploration, commented, “Since we first began
exploration at Bandeira in April 2022, the Project has consistently exceeded our expectations.
What started with just two promising rock samples has evolved into one of the largest spodumene-
rich pegmatite deposits in the Jequitinhonha Valley. I am extremely proud of the capability,
dedication, and achievements of our entire exploration team, and we believe there is still
significant potential ahead.”
The NI 43-101 technical report for the Bandeira MRE (the “Technical Report”), will be accessible
on SEDAR+ ( www.sedarplus.ca) under the Company’ issuer profile, and on the Company’s
website, www.lithiumionic.com, within 45 days of this news release.
About the Bandeira Project
Bandeira covers 158 hectares, less than 1% of Lithium Ionic’s 17,000-hectare land position, but
has rapidly advanced to become one of the most promising lithium development-stage assets in
Brazil. It is located adjacent to Sigma Lithium’s Grota do Cirilo and Barreiro projects and directly
beside Companhia Brasileira de Lítio’s (CBL) long-standing underground lithium operation.
The Company has also established NI 43 -101 compliant mineral resource estimates at two
additional properties within the “Lithium Valley”, Baixa Grande (formerly Salinas) and Outro Lado.
Together, these assets bring Lithium Ionic’s consolidated global mineral resource base to 36. 76
million tonnes (“Mt”) (1,188,473 LCE) in the Measured and Indicated category, in addition to 31.87
Mt (936,196 LCE) in the Inferred category, with the majority of the Company’s regional land
package remaining largely unexplored.
A NI 43-101 compliant f easibility study (the “Feasibility Study” , the “Study” ) for Bandeira was
announced on May 29, 2024, which outlined strong project economics, including a post -tax
NPV8% of US$1.31 billion and an IRR of 40% . This Study was based on a smaller MRE with a
data cut-off of November 13, 2023. This Feasibility Study remains valid and will be part of the
forthcoming Technical Report, however the Company intends to integrate the expanded MRE into
an updated Feasibility Study in the second half of 2025. On April 2, 2025, the Company engaged
the globally recognized lithium advisory firm, RTEK International DMCC (“RTEK”) , to help
transition Bandeira from feasibility to construction and operations.

Details related to the calculation of the MRE
The MRE was prepared by Carlos Silva P.Geo., M.Sc., of GE21 (the “Author” or “QP”) with an
effective date of November 20, 2024.
The MRE was prepared using the following geological and resource block modeling parameters
which are based on geological interpretations, geostatistical studies, and best practices in mineral
estimation.
The QP is not aware of any factors or issues that materially affect the MRE other than normal
risks faced by mining projects in the province in terms of environmental, permitting, taxation,
socio-economic, marketing, and political factors, and additional r isk factors regarding inferred
resources.
• The Project geology comprises Neoproterozoic age sedimentary rocks of Araçuaí Orogen
intruded by fertile Li -bearing pegmatites originated by fractionation of magmatic fluids from
the peraluminous S-type post-tectonic granitoids of Araçuaí Orogen. Lithium mineralization is
related to concordant and discordant swarms of spodumene- bearing tabular pegmatites
hosted by cordierite-biotite-quartz schists.
• Drilling conducted by Lithium Ionic included diamond core drilling of NTW (64.2mm diameter).
• Diamond core has been sampled in intervals of ~ 1 m where possible, otherwise intervals less
than 1 m have been selected based on geological boundaries. Geological boundaries have
not been crossed by sample intervals. ½ core samples have been collected and submitted for
analysis, with regular field duplicate samples collected and submitted for QA/QC analysis.
• Drill core samples were submitted to SGS Geosol laboratories in Brazil where they were
analyzed for a 31-element suite via ICP90A (fusion by sodium peroxide and finish with ICP -
MS/ICP-OES). Assay data were composited to 1 m.
• The MRE was estimated from the diamond drill holes completed by Lithium Ionic from April
2022 until September 2024. Data from a total of 297 drill holes comprising 10,051 assays were
included in the mineral resources model.
• The 3D modelling of lithium Mineral Resources was conducted using a minimum cut-off grade
of 0.3% Li2O within a preliminary lithological model.
• The interpolation was conducted using Krigging methodology with three interpolation passes.
• The block model was defined by a block size of 12 m long by 12m wide by 4 m thick and
covers a strike length of approximately 1,200 m to a maximal vertical depth of 5 00 m below
surface.
• The MRE was classified as Measured, Indicated and Inferred Mineral Resource based on data
quality, sample spacing, and pegmatite continuity. The Measured Mineral Resource was
defined using a search ellipsoid of 50 m by 50 m by 30 m, and where the continuity and
predictability of the mineralized units was reasonable. The Indicated Mineral Resource was
defined using a search ellipsoid 100 m by 100 m by 50 m. The Inferred Mineral Resource was
assigned to areas where drill hole spacing was greater than 100 m by 100 m by 50 m for all
remaining blocks.
• Classification focused on spatial relation using a minimum of five composites in at least three
different drill holes for the Measured and Indicated resources.
• Validation has proven that the block model fairly reflects the underlying data inputs. Variability
over distance is relatively moderate to low for this deposit type therefore the maximum
classification level is Indicated.
• Mineralization at the deposits extends to surface and is expected to be suitable for open cut
mining; no minimum mining width was applied; internal mining dilution is limited to internal
barren pegmatite and/or host rock intervals within the mineralized pegmatite intervals; based
on these assumptions, it is considered that there are no mining factors which are likely to affect
the assumption that the deposit has reasonable prospects for eventual economic extraction.
• It is the QP’s opinion that the current classification used is adequate and reliable for this type
of mineralization and MRE.
• The MRE reported is a global estimate with reasonable prospects of eventual economic
extraction.
