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.
