Lithium Ionic Reports 32% Growth in Updated Mineral Resource Estimate at Baixa
Grande - Salinas, Minas Gerais, Brazil
TORONTO, ON, January 14, 2025 – Lithium Ionic Corp. (TSXV: LTH; OTCQB: LTHCF; FSE:
H3N) (“Lithium Ionic” or the “Company”) is pleased to announce an updated NI 43 -101 Mineral
Resource Estimate (“MRE”) for the Baixa Grande Project (“Baixa Grande” or the “Project” ;
formerly referred to as the “Salinas Project”), the main deposit and growth target within its Salinas
group of properties located in northern Minas Gerais State, Brazil (see Figure 1). This updated
MRE highlights the significant expertise of Lithium Ionic’s exploration team in defining and growing
resources efficiently, underscoring the quality and strategic potential of the Baixa Grande deposit
and surrounding claims.
Baixa Grande Mineral Resource Estimate Highlights:
▪ 6.52 million tonnes (“Mt”) in the Measured and Indicated (“M&I”) category, and an
additional 12.90Mt in the Inferred category (see Table 1).
▪ Since the maiden MRE at Baixa Grande announced in April 2024, M&I has increased
11.3%, while Inferred has increased 45%, showcasing the effectiveness of our exploration
approach and the strong potential for further growth in the future.
▪ The MRE incorporates data from 35,734 metres of drilling (167 diamond drill holes). This
additional drilling led to a 32% growth in the total MRE , showcasing the team’s strong
geological understanding and exceptional success through targeted drilling efforts.
▪ In August 2024, Pilbara Minerals announced the acquisition of Latin Resources and their
Colina deposit, located directly west of the Baixa Grande deposit in an all -share
transaction valued at US$369.4 million (see Latin claims in Figure 1).
▪ The potential for significant additional lithium-bearing spodumene mineralization at Baixa
Grande remains very high with the completion of additional drilling in the area.
Blake Hylands, P.Geo., CEO of Lithium Ionic, commented, “ This updated mineral resource
estimate for Baixa Grande is a testament to the remarkable work of our exploration team in
successfully delineating and expanding the deposit with targeted and efficient drilling. Baixa
Grande is proving to be a key contributor to our long- term growth and production strategy. I am
confident in our team’s ability to further enhance and upgrade these resources and continue to
reinforce the importance of the Salinas group of properties within our portfolio. While our near -
term focus remains on advancing Bandeira toward production, we are excited by the continued
growth potential at Baixa Grande and other regional targets, and their role in supporting our vision
of becoming a leading lithium producer.”
Carlos Costa, P.Geo., Lithium Ionic’s VP of Exploration, commented, “This updated NI 43- 101
mineral resource estimate highlights the outstanding achievements of our exploration team and
the quality of our assets. The nearly 20Mt resource at Baixa Grande reflects not only the
geological potential of the deposit but also the expertise of our technical team in unlocking value
efficiently.”
Baixa Grande Project, Salinas Group of Properties
The Baixa Grande target, located within the Salinas group of properties acquired in March 2023,
has quickly become one of the most promising growth assets in the Company’s portfolio. These
properties are l ocated approximately 100 kilometres north of the Company’s Bandeira
development project, within the northern section of Brazil’s Eastern Pegmatite Province, a region
that is highly prospective for spodumene-bearing pegmatites. The nearly 20Mt mineral resource
at Baixa Grande is an important addition to the Company’s total resources, which further solidifies
its position as a leading lithium company in the region.
In August 2024, Pilbara Minerals announced the acquisition of Latin Resources and their Colina
deposit, located directly west of the Baixa Grande deposit. This acquisition marked Pilbara’s first
diversification into the Americas, underscoring the quality, quantity and global competitiveness of
Brazil’s lithium deposits in this region.
The Baixa Grande MRE i s located on a 662 -hectare property, a small portion of Lithium Ionic’s
large 17,000-hectare land package (See Figure 1).
Baixa Grande Mineral Resource Estimate
The MRE was prepared by GE21 in accordance with National Instrument 43-101 - Standards of
Disclosure for Mineral Projects (“NI 43-101”).
This updated estimate builds upon the maiden MRE announced on April 4, 2024 , incorporating
expanded data from 167 diamond drill holes comprising 35,734 metres of drilling completed
between May 2023 and September 2024.
This added drilling has increased the total mineral resource estimate at Baixa Grande by 32%,
now totaling an estimated 6.52Mt grading 1.11% Li ₂O, containing 179,580 tonnes of Lithium
Carbonate Equivalent (“LCE”), in the M&I category, in addition to 11.67Mt grading 0.97% Li₂O, or
280,730 tonnes of LCE, in the Inferred category for open pit and 1.23Mt grading 0.83% Li₂O, or
25,190 tonnes of LCE, in the Inferred category for underground (see MRE results in Table 1).
Additional drilling at the Noé target, identified previously as having high potential for spodumene
mineralization, yielded an initial Inferred resource estimate. Current interpretation suggests that
the modelled pegmatites potentially increase at depth. Additional drilling is planned to confirm
these observations.
Exploration efforts to date have laid a strong foundation for Baixa Grande’s future development.
The deposit remains open at depth and along strike, providing significant potential for further
resource growth.
The NI 43- 101 technical report for the MRE, 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.

Details related to the calculation of the Baixa Grande MRE
The MRE was authored by Leonardo Soares, P.Geo., M.Sc., of GE21 (the “Author” or “QP”) with
an effective date of December 2, 2024. This updated MRE follows the maiden MRE for Baixa
Grande (previously referred to as “Salinas”) announced on April 4, 2024.
The MRE was estimated 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 risk 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 since May
2023. A total of 167 drill holes comprising 4,036 assays were used for 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 16 m long by 16 m wide by 4 m thick and
covers a strike length of approximately 1, 200 m to a maximal vertical depth of 300 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 MRE 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 MRE was defined using a search ellipsoid
100 m by 100 m by 50 m. The Inferred MRE category 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 mineral resource estimate.
• Initial Metallurgical tests results are not available at this stage of project advancement. An
assumed concentrate (DMS) recovery of 65% has been applied in determining reasonable
prospects of eventual economic extraction.
• Mineral Resources were constrained within the boundaries of an optimized pit shell using the
following constraints: Concentrate price: USD$2,750; mining costs: USD$2.5/t ROM;
Processing costs: USD$12.5/t ROM, General/Admin: USD$ 3.0/t ROM, Lithium Recovery:
65%, Mining Recovery: 100% and Pit slope: 56° in fresh rock and 37° in saprolite.
• The MRE reported is a global estimate with reasonable prospects of eventual economic
extraction.
