Allied Critical Metals Further Highlights Rapid Payback, Capital Efficiency and Infrastructure from Borralha PEA

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 WO₃ (USD $704/mtu WO₃)$1,365/mtu WO₃ (USD $1,000/mtu WO₃), and $2,049/mtu WO₃ (USD $1,500/mtu WO₃), while mine design and cut-off grade selection were developed using a conservative tungsten price assumption of $900/mtu WO₃ (USD $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 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).
