Vancouver, British Columbia--(Newsfile Corp. - March 10, 2026) - Allied Critical Metals Inc. (CSE: ACM)

(OTCQB: ACMIF) (FSE: 0VJ0) ("Allied" or the "Company") is pleased to provide additional economic

and technical detail from the recently announced Preliminary Economic Assessment ("PEA") for its

100%-owned Borralha Tungsten Project (the "Borralha Project") in northern Portugal. The Borralha

Project's previously announced PEA economics remain unchanged.

This news release is an amending and restating news release clarifying and correcting the

immediately preceding news release dated March 9, 2026 to present figures consistently using

North American decimal nomenclature rather than European comma nomenclature. In

addition, Table 3 was updated to address rounding errors, translation errors and currency

conversion using $1.3658 CAD/USD and Table 5 was updated to clarify use of USD $M.

Roy Bonnell

, CEO & Director of Allied, commented:

"Following the release of our initial PEA for the

Borralha Project, we received strong investor interest in additional project-level detail. This

supplementary disclosure highlights the Project's capital efficiency, strong annual cash generation

and well-developed infrastructure platform. Importantly, the underlying economics of the PEA remain

unchanged, while the additional payback presentation provides another useful reference point for

investors evaluating project returns and the strong leverage the Borralha Project has to tungsten

prices."

This additional disclosure provides greater clarity on Borralha Project's capital efficiency, expected cash

flow generation and rapid capital recovery profile. The PEA outlines a capital-efficient underground

tungsten development project within the European Union, demonstrating strong economic returns across

a range of tungsten price assumptions and significant leverage to current market prices. The estimated

capital expenditures for the build out of the Borralha Project are the result of advanced project

infrastructure that a planned hydro-electric power connection, water supply and recycling systems, road

access, and paste backfill integration to support operations while minimizing environmental footprint.

The PEA continues to demonstrate a technically robust and capital-efficient underground tungsten

development project within the European Union. As previously announced, the PEA was evaluated under

three pricing frameworks:

the Base case of $962/mtu WO

(USD $704/mtu WO

)

,

$1,365/mtu WO

(USD $1,000/mtu WO

)

, and

$2,049/mtu WO

(USD $1,500/mtu WO

)

, while mine design and cut-off

grade selection were developed using a conservative tungsten price assumption of

$900/mtu WO

(USD $659/mtu WO

)

. The Company is providing the additional metrics below to facilitate investor

understanding of project capital intensity, cash flow generation and payback presentation. For additional

information, please see the news release dated March 2, 2026.

For additional reference, the Company is presenting payback under two different measurement bases.

The previously disclosed payback metrics were measured from the

start of construction (SC)

,

consistent with standard technical study practice. To facilitate comparison with industry benchmarks, the

Company is also providing indicative payback measured from the

commencement of commercial

production (CCP)

.

Payback measured from the start of construction reflects recovery of initial capital over the full

development and operating timeline, while payback measured from the start of commercial production

excludes the construction phase and is presented for comparative reference only.

The results highlight significant sensitivity to tungsten price while maintaining positive economics under

conservative long-term assumptions.

In the Base Case scenario, tungsten (WO

) represents approximately

96% of project NPV

, with minor

contributions from copper (~3%) and tin (<1%), based on NSR contribution. This highlights that the

Borralha Project economics are overwhelmingly driven by tungsten.

For reference, current reported tungsten market prices remain materially above the USD $1,000 per mtu

sensitivity case presented in the PEA, reaching approximately $2,998 per mtu (USD $2,195 per mtu) as

of March 6, 2026 (Source: Fastmarkets).

Mineral Resource Estimate

This initial PEA is based on the updated Mineral Resource Estimate ("MRE" or "2025 MRE") for the

Santa Helena Breccia at the Borralha Project, which were presented in accordance with National

Instrument 43-101 -

Standards of Disclosure for Mineral Projects

("NI 43-101") in the Company's current

technical report on Borralha (the "Technical Report") entitled "Technical Report on the Borralha Property,

Parish of Salto, District of Vila Real, Portugal", dated effective December 30, 2025, which is published

on the Company's website at

www.alliedcritical.com

and under its profile on SEDAR+ at

www.sedarplus.ca

.

Under the 2025 MRE, the Santa Helena Breccia has been tested by 41 drill holes and surface trenching

over approximately 400 meters of strike length and to depths exceeding 350 meters below surface.

Mineralization remains open along strike and at depth. The cut-off grade of 0.09% WO

3

was selected

based on reasonable prospects for eventual economic extraction under conceptual underground mining

and gravity-dominant processing assumptions, including a very conservative tungsten price of USD $

550/mtu WO

and assumed recovery of approximately 80% (for MRE cut-off determination only).

, with sustaining

capital

[8]

of approximately

USD $87 million

and total life-of-mine capital

[9]

of approximately

processed, based on the Sub-Level Long Hole Stoping

(SLOS) mining method. Limited areas may utilize Drift & Fill mining, which carries higher unit costs. In the economic model, operating costs are

expressed in

nominal US dollars and escalated annually for inflation

, resulting in an average life of mine operating cost of approximately

US$59/t

processed, including transportation and treatment/refining charges.

Concentrate Marketing Assumptions

The PEA assumes production of a marketable tungsten concentrate grading approximately

65% WO

using a gravity-dominant flowsheet. Concentrate pricing assumptions are based on industry-standard

tungsten concentrate marketing structures, incorporating typical 80% payability terms and treatment

charges applicable to the tungsten market.

The Borralha Project benefits from relatively clean mineralogy dominated by

wolframite

, which generally

reduces impurity-related penalties relative to more complex tungsten concentrates.

Capital Efficiency

The relatively modest initial capital requirement reflects several favourable project characteristics,

including but not limited to:

compact underground mining footprint

gravity-dominant processing flowsheet

access to regional infrastructure including electrical grid power

limited earthworks due to site topography

moderate plant throughput of 1.4 million tonnes per annum (Mtpa) of mineralized material

potential Portuguese investment incentives

These factors contribute to a capital-efficient development scenario compared with many global tungsten

projects.

Simplified Annual Cash Flow Metrics

The initial Borralha Project mine plan is expected to generate strong annual cash flow

[11]

supported by

life-of-mine average production of approximately

1,708 tonnes WO

per annum

, a nominal processing

rate of

1.4 Mtpa

, and an average mill feed grade of approximately

0.20% WO

Infrastructure and Site Requirements

The Borralha Project benefits from favourable site conditions and access to existing regional

infrastructure, supporting a capital-efficient development.

Surface infrastructure has been designed to concentrate industrial and administrative facilities within a

compact footprint, minimizing environmental disturbance while ensuring operational efficiency. The

process plant, paste backfill facility, workshops, administrative buildings and support infrastructure will

be located on a centralized platform adjacent to the orebody.

Access to the site will utilize existing regional roads connected to the municipal road CM1025-2.

Dedicated routes for light and heavy vehicles have been designed to ensure safe operations while

minimizing earthworks and environmental impact.

A comprehensive water management system has been designed to support mining and processing

operations. Water supply is expected to be sourced from local groundwater and surface water

resources, with water recycling integrated into the process flowsheet. Three retention basins will provide

operational water storage, sedimentation and environmental control.

Electrical power will be supplied through connection to the Portuguese national grid via a planned 60 kV

overhead line linking the Borralha substation to the SE Frades (REN) substation over approximately 6.5

km. The design complies with applicable national standards and incorporates environmental protection

measures.

The project infrastructure design integrates processing, backfill, water management and power supply

systems to support efficient underground mining operations while minimizing environmental impact.

Key Infrastructure Advantages

Grid power connection (60 kV line - 6.5 km)

Local groundwater and surface water available for operations

Existing regional road access to site

Compact site layout minimizing environmental footprint

Paste backfill and water recycling integrated into plant design

Ongoing Growth Strategy

The current initial PEA is based only on the

Santa Helena Breccia

deposit and an initial

11-year

production plan. The Company's fully funded

20,000-metre

drill program is underway and is targeting:

expansion of the current Mineral Resource;

conversion of Inferred Mineral Resources into higher-confidence categories;

potential extension of mine life beyond the initial plan; and

evaluation of throughput optimization and future project scale growth.

The Company intends to continue advancing Borralha through additional drilling, engineering

optimization, metallurgical refinement, geotechnical and hydrogeological studies, and progression

toward the next stage of technical study.

Cautionary Statement Regarding Forward-Looking Information

This news release contains "forward-looking information" within the meaning of applicable Canadian

securities laws ("

FLI

"). FLI in this release includes, without limitation, statements regarding: (A) the PEA

results and economic indicators (e.g., NPV, IRR, payback and related sensitivities); (B) the conceptual

mine plan and operating framework (mining approach, processing rates, production profiles, cost

ranges and schedules); (C) the technical basis and process assumptions (cut-off approach, flowsheet

concept and anticipated concentrate specifications); (D) the status and trajectory of permitting and

approvals, infrastructure access and other site requirements; (E) market-related assumptions and the

Project's sensitivity and leverage to commodity pricing; (F) growth, conversion and expansion

opportunities, including planned drilling and other technical programs; (G) the anticipated sequence of

future studies, potential financing pathways and indicative timelines; and (H) the Project's strategic

positioning relative to regional and policy objectives. Such FLI is identified by, among other things,

words such as "plans", "expects", "is expected", "aims", "budget", "scheduled", "estimates", "forecasts",

"intends", "anticipates", "potential", "target", "opportunity", "may", "could", "would", "might", "will" and

similar terminology, as well as statements regarding outcomes that "will", "should" or "would" occur.

Material assumptions underlying the FLI include, but are not limited to: the accuracy of the 2025 MRE;

geological continuity; the PEA-level capital/operating cost estimates (with typical PEA accuracy ranges);

metallurgical recoveries and process performance consistent with test results to date; availability of

labour, equipment and consumables at quoted/priced levels; access to grid power and water on

contemplated terms; the ability to obtain land access, permits and approvals (including RECAPE) in a

timely manner; tungsten pricing consistent with Argus long-term forecasts or stated sensitivity cases;

foreign exchange and inflation consistent with study inputs; and availability of financing on acceptable

terms. The Company believes these assumptions are reasonable as of the date hereof, but no

assurance can be given that they will prove correct.

The PEA is preliminary in nature and 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. There is no certainty that the PEA results will be realized. Mineral

Resources are not Mineral Reserves and do not have demonstrated economic viability. Any reference to

potential production, mine life, NPV, IRR, payback, costs, recoveries, or other economic or technical

parameters is preliminary and conceptual.

Key risks and uncertainties that could cause actual results to differ materially from those expressed or

implied by the FLI include, but are not limited to: (i) exploration, geological, modelling and grade-

continuity risks, including the risk that further work does not confirm Inferred material or resource

extensions; (ii) risks that metallurgical performance, WO

recoveries, concentrate quality or processing

costs differ from test work and assumptions; (iii) capital cost escalation, schedule delays, contractor

availability and supply-chain constraints; (iv) operating cost inflation (power, reagents, labour,

transportation); (v) commodity price and FX volatility (including sustained periods below the Argus long-

term or sensitivity prices assumed); (vi) permitting, environmental, social, community, land access and

regulatory risks in Portugal (including RECAPE outcomes and permit conditions); (vii) water, tailings and

geotechnical/hydrogeological risks inherent in underground operations; (viii) offtake, marketing and

market-access risks for tungsten concentrates; (ix) availability and cost of equity, debt or project finance

on acceptable terms; (x) changes in laws, regulations, taxes, royalties, or government policies; and (xi)

other risks described under "Business Risks" in the Company's most recent MD&A and in other

continuous disclosure filings available on SEDAR+. Readers are urged to carefully review those risk

factors, which are expressly incorporated by reference into this cautionary note.
