Martin Kepman, CEO of Manganese X, states, “We are extremely pleased with the positive economics
demonstrated by our PEA. Our Battery Hill Mineral Resource has the potential to be the most impressive
manganese propert ies in North America and has several attributes that make it attractive for
development and commercialization. Battery Hill has robust economics, strong value metrics and a short
payback period for a relatively low capital investment. The PEA represents the most significant milestone
to date for Manganese X and makes us the forerunner of becoming the first publicly traded company in
Canada and the US to commercialize high -purity electric vehicle ( EV) quality compliant manganese.
Thanks to our proprietary extraction process, we can develop a superior quality manganese product by
eliminating selenium, considered a toxic pollutant and yet utilized by some of the HPMSM producers
worldwide to reduce their costs of production. Given selenium is a highly toxic element, its use negatively
impacts the environment and is known to affect the quality of downstream products, particularly for high-
end applications such as lithium -ion-battery production. Our final product should be ab le to justify a
premium to the market price.”
Martin Kepman continues, “The Company has been working diligently on corporate development beyond
the PEA and is currently in discussion with a number of interested parties. This is a very exciting time in
history for manganese as it relates to battery chemistry and the EV revolution, m aking it an equally
exciting time for Manganese X. We intend to be at the forefront of a domestic supply as well as meeting
the expectations of North American battery manufacturers.”

The PEA is preliminary in nature; it includes Inferred Mineral Resources that are considered too
speculative geologically to have the economic considerations applied to them that would enable them to
be categorized as Mineral Reserves, and there is no certainty that the preliminary economic assessment
will be realized. Mineral Resources are not Mineral Reserves and do not have demonstrated economic
viability.
PEA Summary
Mineral Resource Estimate Update:
The Mineral Resource estimate has been reported in accordance with NI 43 -101 and was prepared by
Mercator Geological Services Ltd. (“Mercator”) with an effective date of 12 May 2022. The 2021 Mineral
Resource statement has been renewed to reflect updated costs and an HPMSM price as per a market
analysis report recently obtained. The Mineral Resource estimate is tabulated in Table 3.
Table 3: Battery Hill Deposit Mineral Resource Estimate – Effective Date May 12, 2022
Cut-off (Mn %) Category Tonnes (Million) Mn (%) Fe (%)
1.5
Measured 11.32 6.72 10.94
Indicated 23.82 6.24 10.50
Measured Plus Indicated 35.14 6.39 10.64
Inferred 27.72 6.46 10.73
Notes:
1) Mineral Resources were prepared in accordance with the CIM Definition Standards for Mineral
Resources and Mineral Reserves (MRMR) ( May 2014) and CIM MRMR Best Practice Guidelines
(November 2019).
2) Mineral Resources are defined within an optimized pit shell with average pit slope angles of 45⁰
and a 2.9:1 strip ratio (waste: mineralized material).
3) Pit optimization parameters include: pricing of US $2,900 (CDN $3,625)/t for HPMSM (HPMSM =
32% Mn; CDN $1.25 to US$ 1.00 exchange rate), mining at CDN $7.43/t, a 3% gross metal royalty,
combined processing and G&A (1 ,000 tpd process rate) at CDN $12 6.31/t processed, an overall
Mn recovery to HPMSM of 78%, and a selling cost of US $65.00/t HPMSM. Fe content did not
contribute to the pit optimization process but was applied for bulk density determination
purposes (see note 6).
4) Mineral Resources are reported at a cut-off grade of 1.5 % Mn within the optimized pit shell. The
cut-off grade reflects the marginal cut -off grade used in pit optimization to define reasonable
prospects for eventual economic extraction by open pit mining methods.
5) Mineral Resources were estimated using Ordinary Kriging methods applied to 3 m downhole assay
composites. No grade capping was applied. Model block size is 5 m by 5 m by 5 m.
6) Bulk density was applied using a regression curve based on Mn % and Fe % block grades. Average
bulk density for Mineral Resources is 3.01 g/cm3.
7) Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation,
sociopolitical, marketing, or other relevant issues.
8) Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
9) Figures may not sum due to rounding.
Infrastructure:
The Project is located approximately 6 km northwest of th e town of Woodstock and is accessible to the
east via a new two -lane road that connects with Highway 560. Key site infrastructure includes security
and administration, crushing facility, process plant and ancillaries, sulphuric acid plant, mining faciliti es
(truck shop and maintenance), waste rock storage facilities, run of mine mill feed stockpile and filtered
residue storage area, sedimentation ponds, power, water and fuel supply and distribution. Filtered
residue from the process plant will be trucked to the filtered residue storage area for the first 24 years of
mine production after which residue will be trucked to the Moody Hill Pit 2 and backfilled.
Metallurgical Test Work:
Phase three of preliminary metallurgical test work completed by Kemetco Research Inc. (“Kemetco”) has
resulted in the refinement of a conceptual flowsheet and estimated mass balance to support the
PEA. Test work focused on defining key process steps to establish major equipment requirements,
reagent consumption and ma nganese recovery. The following main conclusions highlight the results
drawn from this test program:
• Leaching and neutralization optimization resulted in improved solid -liquid separation and allowed an
incremental increase in recovery
• Leach extractions on Moody Central mineralization were between 83 and 88%
• Effective removal of calcium and magnesium from leach solutions was demonstrated with the removal
of up to 90% of both elements from leach solution
• Crystallization of manganese sulphate from evaporated and purified feed solutions was readily
achieved
• The overall recovery to HPMSM is estimated to be 78%
• Final neutralized and washed solid residue samples showed little or no acid generation potential and
all had positive neutralization potential . Toxicity characteristic leaching procedure ( TCLP) tests were
negative for all elements of concern.
Metallurgical Test Work Recommendations:
• Leaching parameters, leach solution purification and the crystallization processes will require further
definition and optimization for both recovery and impurity rejection
• Additional locked-cycle testing is required on leach and neutralization, purification, crystallization and
bleed stream treatment
• Pilot plant testing will demonstrate the process and gene rate sufficiently large HPMSM samples for
end-user testing.
Process Method:
The proposed process for treating Battery Hill manganese resources is a whole ore sul phuric acid slurry
leach performed under conditions which result in formation of a filterable r esidue. Leach solution is
neutralized with a calcium base, concentrated by evaporation and purified through a proprietary selective
cation removal process. The purified liquor is then further evaporated to produce a crystalline manganese
sulphate monohydrate product meeting all specifications for sale as a battery grade product.
Mining Method:
The PEA mine plan assumes conventional open pit mining using a contract mining equipment fleet at a
total mining rate of 1.0 million tonnes per year to provide a mill feed of 365,000 tonnes per year, or 1,000
tonnes per day. The ultimate pits and mine plan use an elevated cut-off grade strategy to help drive the
project economics. The use of a stockpile for mineralized material allows higher-grade material to be
processed early in the mine life to enhance project economics and to sustain mill operations 24-hours per
day, seven-days per week at a single, central processing facility. The mining operations will have a 40 -
year mine production life, with a two-year pre-production period, and seven years of stockpile reclaim
feed.
Independent Qualified Persons Statements:
The PEA was prepared for Manganese X by independent Qualified Persons (QPs) as defined under NI 43-
101 from Wood and Mercator and are listed below. The independent QPs have prepared and approved
the scientific and technical information disclosed in this press release derived from their respective
sections of the technical report:
• Mr. Paul Baluch, P.Eng., Technical Director Civil/Structural/Architectural, Wood

• Mr. Paul Ténière, P.Geo., Senior Associate Geologist, Mercator
• Mr. Gil Violette, P.Eng., New Brunswick, Principal Hydrogeologist, Wood
• Mr. Piers Wendlandt, P.E., Principal Mining Engineer, Wood
Data Verification:
QP Harrington performed standard validation checks on the Mineral Resource model.
QP Drake visited the Kemetco testing facilities and had discussions with those who performed the test
work, identified the drill holes and the intervals in which the metallurgical test samples were taken.
QP Gosson discussed with the marketing expert from CPM Group regarding the basis of their market
analysis and price forecast.
QP Ténière visited the Project site and compared select core intervals with original drill logs and sampled
intervals, collected independent witness s amples, reviewed quality assurance and quality control
procedures, and completed a field inspection.
QP Violette visited the Project site during which he viewed drill core, completed field inspections of the
Moody Hill target and surrounding areas, and assessed local infrastructure.
A description of the data verification methods for the Mineral Resource estimate is contained within the
technical report previously filed on Manganese X’s SEDAR profile (NI 43-101 Technical Report Battery Hill
Project Mineral Resource Estimate, Woodstock Area, New Brunswick, Canada with effective date 18 June
2021).
Project Risks:
• The geological interpretation and assumptions on grade continuity based on limited drilling may
change with more detailed drilling.
• There may be unre cognized metallurgical variability that could change the mine plan, metallurgical
recoveries and/or process costs.
• With more project definition and engineering input, the capital costs may change more than the
contingency allowance.
• Assumptions regarding supply demand forecasts for HPMSM, market entry strategy and HPMSM price
may not be realized because of supply chain constraints.
• Permitting remains uncertain until more detailed environmental base line studies are completed.
• Community engagement is at an early stage and there is uncertainty regarding what is necessary for
obtaining a social license to develop a mine.
• Footprint for establishing the project infrastructure will require agreements from local landowners
which is at an early stage of assessment.
• Interpretation of the property agreements may be different to what has been assumed for the study.
