Highlights:

• One of Europe’s Premier Emerging Tungsten Assets materially increases its mineral resource estimates with Measured and Indicated Resource Estimate (M+I) increasing to 13.0 Mt at 0.21% WO₃ and Inferred Resource Estimate to 7.7 Mt at 0.18% WO₃.

Allied Critical Metals Inc. (CSE: ACM,OTC:ACMIF) (OTCQB: ACMIF) (FSE: 0VJ0) (‘Allied’ or the ‘Company’), which is focused on its 100% owned past producing Borralha and Vila Verde tungsten projects in northern Portugal, is pleased to announce an updated Mineral Resource Estimate (‘MRE’) at the Company’s Borralha Tungsten Project. The MRE is only with respect to the Santa Helena Breccia and does not include other potential mineralized deposits on the property. This update incorporates results from the 2025 Phase 1 RC drilling (4,210 metres) campaign and represents a significant step in advancing the Borralha Project toward a Preliminary Economic Assessment (‘PEA’) targeted for Q1, 2026. It is particularly timely as tungsten prices remain strong at approximately U.S. $700MTU APT, up about 70% over the past six months amid increasing demand for critical raw materials and tightening global supply.

The updated MRE marks a major step change from the 2024 MRE (4.98 Mt Indicated at 0.21% WO₃ and 7.01 Mt Inferred at 0.20% WO₃), with the Borralha resource now at 13.0 Mt Measured and Indicated (M+I) at 0.21% WO₃ and 7.7 Mt Inferred at 0.18% WO₃, confirming the Santa Helena Breccia as one of the largest undeveloped tungsten systems in Europe.

UPDATED MINERAL RESOURCE ESTIMATE (MRE)
(Effective date: 16 November 2025; based on 0.09% WO₃ cut-off; undiluted in-situ; WO₃-only.)

TABLE 1 — Mineral Resources at 0.09% WO₃ Cut-off

* The MRE was prepared in accordance with the CIM Definition Standards (2023) and National Instrument 43-101—Standards for Disclosure of Mineral Projects (‘NI 43-101‘) and replaces the previous maiden resource dated March 25, 2024.

Roy Bonnell, CEO & Director of Allied, commented: ‘This updated MRE is a major milestone for the Borralha Project. Growing the Measured and Indicated resources to 13.0 million tonnes at 0.21% WO₃ and Inferred resources to 7.7 million tonnes at 0.18% WO₃ while keeping the system open in multiple directions confirms both the scale and continuity of the deposit. The Borralha Project continues to impress by continuing to produce record tungsten intercepts. With our next core drilling campaign planned for early 2026, we are confident that this project will continue to expand and strengthen its position as one of Europe’s most compelling tungsten assets.’

‘This updated MRE strengthens not only the technical foundation of the Borralha Project, but also our position within the ongoing environmental and permitting processes, with anticipated approvals in Q1, 2026. It provides an excellent foundation to further build the MRE for our anticipated PEA in Q1 2026 by, among other things, pairing two or three holes to reach more mineralization which weren’t accessible with RC in this campaign. Alongside the drilling and geological work, our team has been advancing the Environmental Impact Assessment and navigating the extensive regulatory and administrative steps required in Portugal. Today’s results support the robustness of the project as we progress through these parallel workstreams. The combination of geological growth, improving confidence, and continued permitting momentum gives us a clear and responsible path forward toward development.’

Note: In accordance with NI 43-101 Section 3.5, Mineral Resources are reported separately by category and must not be aggregated. Measured and Indicated Resources may be combined for reporting purposes, but Inferred Resources cannot be added to other categories. No combined grade is reported for Measured + Indicated + Inferred.

Highlights:

• New MRE incorporates 1) RC step-outs, 2) infill drilling, 3) density updates, 4) revised grade shell, 5) improved geological model 6) enhanced geostatistical parameters.

• WO₃-only cut-off grade is 0.09% WO₃, consistent with the expectable underground LHOS potential and gravity-dominant metallurgy.

• Strong continuity of mineralization confirmed; extensions defined toward the north dip and western flank.

• Metallurgy indicates simple, low-cost gravity flowsheet with ~75-85% WO₃ recovery and potential Cu-Sn-Ag by-product upside to be defined in the PEA.

• Updated block model supports growing potential for scalable, long-life underground operation.

• The final RC holes were terminated before reaching the anticipated mineralized corridors, leaving the western and northern down-dip extensions open. This indicates that significant potential remains for additional resource growth with only modest further drilling, which will be addressed in the next core drilling campaign planned for Q1 2026.

GEOLOGICAL & METALLURGICAL CONTEXT

Drilling confirms that the Santa Helena Breccia is a large, subvertical, coarse-fragment collapse breccia, strongly mineralized in wolframite ± ferberite, with accessory cassiterite, chalcopyrite, silver sulphosalts, and low deleterious elements. Mineralization displays strong structural control and excellent lateral continuity. This updated MRE does not yet take into account any future breccia complexes or other geological anomalies that may be present at the Borralha Project.

Metallurgy

Existing metallurgical programs (bench-scale testing, mineralogical studies, and semi-industrial work by MinePro), together with ongoing metallurgical test work at Wardell Armstrong International (SLR), indicate:

• Coarsely liberated wolframite, well suited to gravity concentration.
• Heavy Liquid Separation (5 mm) delivering exceptional performance, rejecting >50% of the mass at high WO₃ recovery.
• Spirals and shaking tables effective for fine clean-up stages.
• Final sulfide flotation required to clean the gravity concentrate and remove sulfide minerals.
• Cassiterite and chalcopyrite exhibit realistic beneficiation potential, with metallurgy to be provided by MinePro’s independent QP for the NI 43-101 Technical Report.
• Wardell Armstrong (UK) test work is underway, with results expected in Q1 2026 to support PEA flowsheet definition and recoveries.

By-products (Cu-Sn-Ag)

Although not included in cut-off or resource calculation:

• Chalcopyrite follows sulfide flotation which leads to potential Cu concentrate;
• Cassiterite follows gravity circuit which leads to potential Sn concentrate; and
• Ag could report to sulfide concentrate.

These metals represent future upside to be defined within the PEA.

Cut-off grade rationale

Resources are reported above a 0.09% WO₃ cut-off grade, derived from:

• APT price: US $500/MTU;
• Underground long-hole stoping conceptual mining; and
• An implicit 0.09% WO₃ grade shell was constructed using a numeric-model iso-value of 0.6. Minor isolated volumes <5,000 m³ were removed to satisfy CIM RPEEE (Reasonable Prospects for Eventual Economic Extraction) continuity criteria and to avoid isolated blocks lacking reasonable prospects for extraction.

NEXT STEPS

The updated MRE provides the foundation for Allied’s maiden PEA planned for Q1 2026, evaluating a scalable underground operation leveraging gravity-dominant processing with by-product potential. The next steps include:

• Completion of Wardell Armstrong (UK) detailed metallurgy (underway);
• Engineering trade-off studies to support PEA;
• Phase 2 RC & diamond drilling targeting western & down-dip expansion; and
• Environmental and hydrogeological baseline program (ongoing).

About the Borralha Tungsten Project

Allied’s Borralha Tungsten Project is one of the largest and most historically significant past-producing tungsten operations in Western Europe. Located in northern Portugal, Borralha was once the second-largest tungsten mine in the country and supplied strategic materials to European and Allied industries during the 20th century, including both World Wars and the Cold War period.

Today, the project is undergoing a modern revitalization based on a combination of scale, grade, metallurgy, and jurisdictional strength. Mineralization is dominated by coarse-grained wolframite, which is highly desirable in global markets due to its favorable processing characteristics and higher recoveries compared to scheelite-bearing deposits.

Borralha benefits from existing infrastructure, shallow mineralization, and a simple processing route, making it one of the most advanced tungsten development projects in the European Union. These attributes are particularly important in the context of the EU Critical Raw Materials Act (2024/1252) and NATO strategic autonomy initiatives, both of which explicitly identify tungsten as a defense-critical raw material subject to severe supply risk.

With the EU currently dependent on over 80% of its tungsten imports from China, Borralha represents a rare and strategic opportunity to develop a secure, domestic, and NATO-aligned supply source. As Allied continues to advance drilling, resource expansion, and economic studies, Borralha is poised to play a central role in reshaping Europe’s tungsten landscape—supporting both decarbonization technologies and defense-industrial resilience.

ABOUT Allied Critical Metals

Allied Critical Metals Inc. (CSE: ACM,OTC:ACMIF) (OTCQB: ACMIF) (FSE: 0VJ0) is a Canadian-based mining company focused on the expansion and revitalization of its 100% owned past producing Borralha Tungsten Project and the Vila Verde Tungsten Project in northern Portugal.

Vancouver, British Columbia, November 19, 2025 TheNewswire – Prismo Metals Inc. (the ‘ Company ‘) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to report that it has completed a detailed exploration program at the Black Diamond area of its Silver King Project located in Arizona. Work consisted of mapping and sampling of the area including the Black Diamond copper replacement body and the newly encountered strongly altered felsic intrusion with stockwork veining.  A handheld XRF analyzer was used to complete a soil geochemistry grid and to analyze selected rock samples in a qualitative manner. Additionally, an IP survey was recently initiated over the Silver King land package, with results expected by the first week of December.

The soil survey defined a large copper anomaly over the Black Diamond replacement body along with some anomalous gold values. Previous rock samples have shown the copper-gold association of mineralization in replacement mineralization. The soil survey also showed Zn, Pb, Ag and Sb anomalies associated with the felsic intrusion. This intrusion is strongly sericitized and is cut by moderate to strong stockwork quartz veins with locally abundant iron oxides after pyrite.

XRF analysis of rock samples in the area was also completed. Although XRF analyses on rocks are generally qualitative and are not valid assays as are rock samples assayed by the geochemical laboratories, they do indicate the presence of the metals of interest and are useful as guides to mineralization.

XRF analyses of individual quartz veinlets in the stockwork hosted by the felsic intrusion locally indicate the presence of silver, lead and zinc as well as some antimony.  During the exploration program, Prismo’s geological team took 34 rock chip samples over the area. These samples were submitted to the laboratory with assay results expected in the coming weeks.

Craig Gibson, Chief Exploration Officer of the Company, stated: ‘These results confirm Black Diamond as a copper-gold replacement body target as was indicated from previous work, making this area a compelling drill target. The data collected from the felsic intrusion indicated that it is mineralized, a feature that was not indicated in reports from previous work by Fischer Watt in 1980, although they considered it a prime target based on alteration mineralogy and fluid inclusion studies 1 .’

Drill Permit Update

Prismo also announced that the Forest Service, the federal surface land management entity for Silver King, has determined that the Company’s proposed drill plan meets the regulatory requirements for processing, and that such plan is complete, as described in the regulations at 36 CFR 228.4(c).

The Forest Service will now proceed with the environmental analysis pursuant to 36 CFR 228(a)(5) in conformity with the National Environmental Policy Act (NEPA). This analysis will proceed as a Categorical Exclusion, the lowest level of environment reviews applicable to projects that are not expected to have a significant effect on the environment, such as Silver King.

Alain Lambert, CEO of Prismo stated: ‘We are pleased with the steady progress on the permitting front, especially given the now resolved US government ‘shutdown.’

Mr. Lambert added: ‘With the closing of our recent oversubscribed financing, we are fully funded for the first two phases of drilling. In Phase 1, we plan a drill program at the historic Silver King mine site for about 1,000 meters. That drill plan is designed to test the upper half of the steeply dipping pipelike Silver King mineralized body as well as potential mineralization adjacent to the dense stockwork that was the focus of historic mining.’

Given the Company’s recent discoveries, Prismo has added a second phase of drilling for an additional 1,000 meters. This additional program will focus on the newly identified targets outside of the historic mining area, such as the polymetallic vein and the copper vein mentioned above. Drilling of the large body of replacement mineralization on the patented Black Diamond claim is also being planned and is road accessible on private ground.

QA/QC

XRF analyses are considered to be qualitative in nature and cannot be considered to be representative of commercial assays.  XRF soil analyses are useful as they indicate variations in metal contents to represent anomalies, although the actual values of the metals present are not necessarily the same as those obtained from commercial geochemical analyses.  The company uses commercial standards when using the XRF analyzer.

Qualified Person

Dr. Craig Gibson, PhD., CPG., a Qualified Person as defined by NI-43-01 regulations and Chief Exploration Officer and a director of the Company, has reviewed and approved the technical disclosures in this news release.  The historic data presented in this press release was obtained from public sources, should be considered incomplete and is not qualified under NI 43-101, but is believed to be accurate. The Company has not verified the historical data presented and it cannot be relied upon, and it is being used solely to aid in exploration plans. References to mineralization at the Magma Mine and Resolution Copper deposit is not necessarily indicative to the mineralization on the Silver King property.

About the Silver King

Discovered in 1875, the Silver King mine was one of Arizona ‘ s most important historic producers, yielding nearly 6 million ounces of silver at grades of up to 61 oz/t.  The Silver King mine sits only 3 km from the main shaft of the Resolution Copper project — a joint venture between Rio Tinto and BHP and one of the world ‘ s largest unmined copper deposits with an estimated copper resource of 1.787 billion metric tonnes at an average grade of 1.5% copper (1) . The unique land position is fully surrounded by Resolution Copper ‘ s claim block, offering strategic upside. Selected samples from small-scale production in the late 1990s returned grades as high as 644 oz/t silver (18,250 g/t) and 0.53 oz/t gold (15 g/t), indicating that high-grade mineralization remains.
