Cartier Resources Inc. (″ Cartier ″ or the ″ Company ″) (TSXV: ECR,OTC:ECRFF; FSE: 6CA) is pleased to announce the ninth batch of results from the 100,000-m drilling program (2 drill rigs), for the Portal Sector, specifically from the North Simon Zone (″ NSZ ″) on the 100%-owned Cadillac Project, located in Val-d’Or (Abitibi, Quebec).

Strategic Highlights from Portal Sector

Drill Hole Results (Figures 1 to 4)

• CA26-314 intersected 7.1 g/t Au over 8.0 m including 38.8 g/t Au over 1.0 m (NS Zone).
• CA26-325 graded 6.8 g/t Au over 2.2 m (NS Zone).
• CA26-308 reported 3.3 g/t Au over 4.2 m (5C5 Zone).

Significance for Investors

• Holes CA26-314 and 325 confirm the newly recognized NSZ high-grade gold zone near surface. The mineralization extends over 200 m in strike length and remains open in all directions, suggesting significant upside exploration potential.
• Most importantly, NSZ is strategically located just 150 metres east of historical ramp. This logistical advantage should enhance the development flexibility and economics of Cadillac Project.

Next Steps

• Further expansion drilling is planned to significantly refine the geological model, verify the mineralization continuity and determine the gold enrichment vectors.
• Additional exploration drilling is required to test several new high-priority regional targets along strike of the Portal Sector and the Cadillac Fault Zone, backed by detailed structural and geological modelling and VRIFY’s artificial intelligence (AI) driven targeting.

‘ These results of Portal Sector are particularly exciting as they confirm the presence of a fourth gold sector with strong exploration potential. Benefiting from the existing road access and historical infrastructure, this new sector has the potential for resource growth while being strategically located with respect to the Main Sector. We believe it could significantly enhance the value of the project and provide additional flexibility as we continue to advance and expand the overall development opportunities.‘ – Ronan Deroff, Vice President Exploration of Cartier.

Portal Sector

The Portal Sector is a highly prospective area featuring the new North Simon Zone with indicated resources of 9,600 ounces (0.2 million tonnes at 1.9 g/t Au) and inferred resources of 112,600 ounces (1.8 million tonnes at 2.0 g/t Au). The latter is the first ever resource estimate in this sector for which there has been only limited and relatively shallow testing. This sector hosts several newly defined high-priority drill targets.

This sector lies along an east-west trending, strongly sheared corridor (Cadillac Fault Zone) and occurs at the contact between the hanging wall turbiditic sedimentary rocks (wacke-mudrock), locally conglomerates and iron formations of Cadillac Group and the footwall mafic volcanics (basalt) of Piché Group. This lithological unit is a favorable horizon for hydrothermal fluid flow, likely related to synvolcanic gold deposition.

The Portal Sector, defined by at least four parallel gold-rich zones, are typically and primarily associated with a fine-grained and disseminated arsenopyrite-pyrrhotite mineralization, with a pervasive biotite-chlorite-carbonate alteration, all crosscut by late-stage smoky and white quartz vein and veinlet stockworks containing visible gold. Locally, accessory minerals such as pyrite and tourmaline are observed.

Milestones of 2025-2027 Exploration Program

100,000 m Drilling Program (Q3 2025 to Q2 2027)

The ambitious 600-hole drilling program will both expand known gold zones and test new shallow surface high-potential targets. The objective is to unlock the camp-scale, high-grade gold potential along the 15 km Cadillac Fault Zone. It is important to note that Cartier’s recent consolidation of this large land holding offers the unique opportunity in over 90 years for unrestricted exploration.

Environmental Baseline Studies & Economic Evaluation of Chimo mine tailings (Q3 2025 to Q3 2026)

The baseline studies will be divided into two distinct parts which include 1) environmental baseline desktop study and 2) preliminary environmental geochemical characterization. The initial baseline studies will provide a comprehensive understanding of the current environmental conditions and implement operations that minimize environmental impact while optimizing the economic potential of the project. These studies will be supplemented by an initial assessment of the economic potential of the past-producing Chimo mine tailings to determine whether a quantity of gold can be extracted economically.

Metallurgical Sampling and Testwork Program (Q4 2025 to Q1 2026)

The metallurgical testwork program includes defining of expected gold recovery rates and improving historical results from the Chimo deposit, as well as establishing metallurgical recovery data for the first-time for the East Chimo and West Nordeau satellite deposits, where no previous data exists. This comprehensive program will characterize the mineralized material, gold recovery potential and validate optimal grind size defining the most efficient and cost-effective flowsheet. The data generated will directly support optimized project development and have the potential to significantly reduce both capital and operating costs, while also improving the environmental footprint.

Preliminary Economic Assessment (2026)

Internal engineering studies have been initiated to validate a multitude of development scenarios that consider the updated MRE and current market environment. Following the selection of the most optimal scenario, a PEA will be completed which will also build upon the results of the metallurgical testwork program and the environmental baseline studies to unveil the updated development strategy and vision of the project.

Quality Assurance and Quality Control (QA/QC) Program

The drill core from the Cadillac Project is NQ-size and, upon receipt from the drill rig, is described and sampled by Cartier geologists. Core is sawn in half, with one half labelled, bagged and submitted for analysis and the other half retained and stored at Cartier’s coreshack facilities located in Val-d’Or, Quebec, for future reference and verification. As part of Quality Assurance and Quality Control (QA/QC) program, Cartier inserts blank samples and certified reference materials (standards) at regular intervals into the sample stream prior to shipment to monitor laboratory performance and analytical accuracy.

Drill core samples are sent to MSALABS’s analytical laboratory located in Val-d’Or, Quebec, for preparation and gold analysis. The entire sample is dried and crushed (70% passing a 2-millimeter sieve). The analysis for gold is performed on an approximately 500 g aliquot using Chrysos Photon Assay technology, which uses high-energy X-ray excitation with gamma detection to quickly and non-destructively measure gold content.

Alternatively, samples are submitted to Activation Laboratories Ltd. (‘Actlabs’), located in either Val-d’Or or Ste-Germaine-Boulé, both in Quebec, for preparation and gold analysis. The entire sample is dried, crushed (90% passing a 2-millimetre sieve) and 250 g is pulverized (90% passing a 0.07-millimetre sieve). The analysis for gold is conducted using a 50 g fire assay fusion with atomic absorption spectroscopy (AAS) finish, with a detection limit up to 10,000 ppb. Samples exceeding this threshold are reanalyzed by fire assay with a gravimetric finish to determine high-grade values accurately.

Both MSALABS and Actlabs are ISO/IEC 17025 accredited for gold assays and implement industry-standard QA/QC protocols. Their internal quality control programs include the use of blanks, duplicates, and certified reference materials at set intervals, with established acceptance criteria to ensure data integrity and analytical precision.

Vancouver, British Columbia–(Newsfile Corp. – March 9, 2026) – Allied Critical Metals Inc. (CSE: ACM,OTC:ACMIF) (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 (‘Borralha’ or the ‘Project’) in northern Portugal. The Project’s previously announced PEA economics remain unchanged.

Roy Bonnell, CEO & Director of Allied, commented: ‘Following the release of our initial Borralha PEA, 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 Borralha has to tungsten prices.’

This additional disclosure provides greater clarity on Borralha’s capital efficiency, expected cash flow generation and rapid capital recovery profile. The Borralha 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 Borralha 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 WO₃ (US$704/mtu WO₃), $1,365/mtu WO₃ (US$1,000/mtu WO₃), and $2,049/mtu WO₃ (US$1,500/mtu WO₃), while mine design and cut-off grade selection were developed using a conservative tungsten price assumption of $900/mtu WO₃ (US$659/mtu WO₃). The Company is providing the additional metrics below to facilitate investor understanding of project capital intensity, cash flow generation and payback presentation.

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).

Table 1 – Economic Results (After-Tax)

 
Notes:

1. NPV is a Non-GAAP measure; see notes below for additional information regarding NPV. M = million.
2. IRR is a Non-GAAP measure; see notes below for additional information regarding IRR.
3. Payback is a Non-GAAP measure. see notes below for additional information regarding payback.

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 (WO₃) 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 US$1,000 per mtu sensitivity case presented in the PEA, reaching approximately $2,998 per mtu (US$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, 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% WO₃was 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 WO₃ and assumed recovery of approximately 80% (for MRE cut-off determination only).

Table 2 -2025 MRE for Borralha (see also Technical Report for further details)

Initial Capital Allocation and Operational Costs

The Borralha PEA estimates initial capital⁷ of approximately US$91 million, with sustaining capital⁸ of approximately US$87 million and total life-of-mine capital⁹ of approximately US$178 million. The initial capital requirement reflects a compact project design integrating underground mine development, process plant construction and site infrastructure.

Table 3 – Initial Capital Costs

 
*Canadian dollar (CAD) equivalents calculated used a foreign exchange rate of CAD $1.3658/USD.
**EPCM = Engineering, Procurement, and Construction Management.

Certain development expenditures may also qualify for applicable Portuguese investment tax incentives, which could partially offset initial capital expenditures.

Table 4 – Operating Cost¹⁰ Breakdown

 
*TC/RC = Treatment Changes and Refining Charges. These are fees paid by mining companies to smelters to process raw material concentrate into refined metal.
**Operating costs for life-of-mine used for mine design average approximately US$49/t 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% WO₃ 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 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:

• compact underground mining footprint
• gravity-dominant processing flowsheet
• access to regional infrastructure including 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 mine plan is expected to generate strong annual cash flow¹¹ supported by life-of-mine average production of approximately 1,708 tonnes WO₃ per annum, a nominal processing rate of 1.4 Mtpa, and an average mill feed grade of approximately 0.20% WO₃.

Table 5 – Cash-Flow¹¹ Table

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, WO₃ 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.

Non-GAAP Financial Measures

The Company has included certain non-GAAP financial measures in this press release. These financial measures are not defined under International Financial Reporting Standards (‘IFRS‘) and should not be considered in isolation. The Company believes that these financial measures, together with financial measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. The inclusion of these financial measures is meant to provide additional information and should not be used as a substitute for performance measures prepared in accordance with IFRS. These financial measures are not necessarily standard and therefore may not be comparable to other issuers.

Net Present Value (NPV) – is the present value calculation of net profit from operations determined using a particular discount rate. All NPV values stated herein are on an after tax basis.

Internal Rate of Return (IRR) – is a financial metric used to assess an investment’s profitability by calculating the annual rate of return that makes the NPV of all cash flows (both positive and negative) equal to zero.

Payback – is calculated in years as the length of time that it takes to pay off the capital costs from annual net profit expected from operations at the Borralha Project.

Initial capital – is the initial capital cost amount required to be expended to construct the mine and tungsten concentrator process equipment and buildings to begin processing mineralized material into saleable tungsten concentrate at commercial quantities according to the life of mine plan at the Borralha Project. Table 3 above provides a breakdown of the initial capital costs. This is an estimate accurate to +/-35%.

Sustaining capital – is a supplementary financial measure which reflects cash basis expenditures which are expected to maintain operations and sustain production levels at the Borralha Project.

Capital costs or Total life of mine capital costs – include the Initial capital and the sustaining capital.

Operating costs – are the costs required to process mineralized material into saleable tungsten concentrate at the Borralha Project. This includes: underground mining; processing and plant operations; general and administrative costs; and site services and infrastructure support (see Table 4 above for a breakdown of the operating costs). This can be calculated on the unit basis per mtu WO₃ produced.

Cash flow – includes average annual revenue, average annual EBITDA (earnings before interest, taxes, depreciation and amortization), average annual pre-tax cash flow, average annual free cash flow, life of mine revenue, life of mine free cash flow. Average annual revenue is the average annual gross revenue over the life of mine. Average annual EBITDA is the average annual EBITDA over the life of mine. Average annual pre-tax cash flow is the average over the life of mine of the annual free cash flow prior to deduction of taxes. Life of mine revenue is the total gross revenue over the life of mine. Life of mine free cash flow is the total free cash flow over the life of mine. Free cash flows are revenues net of operating costs, royalties, working capital adjustments, capital expenditures and cash taxes. The Company believes that this measure is useful to readers in assessing the Company’s ability to generate cash flows from Borralha.

All-In Sustaining Costs (AISC) – are comprised of sustaining capital expenditures and site level costs to support ongoing operations and closure costs. All-in sustaining costs per mtu WO₃ is calculated as AISC divided by the amount of mtu WO₃ produced during the period that the costs are incurred. All-in sustaining costs capture the important components of the Company’s production and related costs and are used by the Company and investors to understand projected cost performance at the Borralha Project. Adoption of the all-in sustaining cost metric is voluntary and not necessarily standard, and therefore, this measure presented by the Company may not be comparable to similar measures presented by other issuers. The Company believes that the all-in sustaining cost measure complements existing measures and ratios reported by the Company. All-in sustaining cost includes both operating and capital costs required to sustain WO₃ production on an ongoing basis. Sustaining operating costs represents expenditures expected to be incurred at the Project that are considered necessary to maintain production. Sustaining capital represents expected capital expenditures comprising mine development costs, including capitalized waste, and ongoing replacement of mine equipment and other capital facilities, and does not include expected capital expenditures for major growth projects or enhancement capital for significant infrastructure improvements.
