Allied Critical Metals: Advancing Tungsten Projects in Portugal

Vancouver, British Columbia TheNewswire – June 2, 2025: Allied Critical Metals Inc. (CSE: ACM | FSE:0VJ0) (” Allied” or the ” Company” ), which is focused on its 100% owned past producing Borralha and Vila Verde (Vale das Gatas) tungsten projects in northern Portugal, is pleased to announce the commencement of a fully-funded exploration program that will include up to 5,000 metres of core drilling at the Company’s flagship Borralha Tungsten Project (the ” Property” or ” Borralha” ), located in northern Portugal.

Roy Bonnell, CEO and Director commented, “The launch of this 5,000-metre drilling campaign marks a major milestone for Allied and the continued advancement of the Borralha Project. Our experienced geological team in Portugal expects the results to meaningfully expand the current resource base, paving the way for a more robust and valuable project. All newly defined tonnage will be incorporated into an updated Preliminary Economic Assessment (PEA), scheduled for release this fall. In parallel, advanced metallurgical optimization test work will be conducted at Wardell Armstrong’s laboratories in the UK, focusing on enhancing metal recoveries and concentrate grades. These efforts are aimed at further improving the economic performance of the project and delivering a higher-quality concentrate to meet the demanding standards of end-users.”

The Borralha project is an advanced-stage brownfield tungsten project located in northern Portugal. Historically mined between 1904 and 1985, it produced over 10,280 tonnes of high-grade wolframite concentrate averaging 66% WO₃ (as described in the Company’s Technical Report, referenced below). The Borralha project is now positioned for near-term, low-cost production with modern exploration confirming significant remaining mineralization.

Key highlights include:

Current NI 43-101 Resources (as of March 2024):

• Indicated: 4.98 million tonnes at 0.22% WO₃, 762 g/t Cu, and 4.8 g/t Ag.

• Inferred: 7.01 million tonnes at 0.20% WO₃, 642 g/t Cu, and 4.4 g/t Ag.

The Company has completed its maiden mineral resource estimate for the Property described in its technical report entitled, “Technical Report on the Borralha Property, Parish of Salto, District of Vila Real, Portugal” dated effective July 31, 2024 (the ” Technical Report” ), which is available under the Company’s profile on SEDAR+ at www.sedarplus.ca .

Recent Exploration : Drilling from 2023–2024 returned strong intercepts, including up to 10m at 1.75% WO₃ and multiple longer intervals averaging over 0.2% WO₃, as reported in the Technical Report.
