Key Highlights:

• Over 200 metres of breccia-hosted tungsten mineralization intersected, indicating an extensive breccia-hosted alteration and mineralization system (true width not yet determined). Mineralized intervals are consistent with the interpreted Venise Breccia geological model.

• Located approximately 400 metres from the Santa Helena Breccia deposit, which underpins the Company's recently announced PEA mine plan, highlighting near-mine expansion potential.

• Drillhole intersected zones containing visible wolframite tungsten mineralization, with associated molybdenite and chalcopyrite within quartz-sulphide veining.

• Observations support the interpreted continuity of a historically recognized breccia system that had not previously been systematically tested using modern exploration methods.

• Presence of molybdenite and chalcopyrite suggests potential polymetallic mineralization consistent with other breccia systems in the district.

• Part of a fully funded 20,000-metre drill program targeting resource growth, mine life extension and project scale expansion.

Vancouver, British Columbia--(Newsfile Corp. - April 7, 2026) - Allied Critical Metals Inc. (CSE: ACM) (OTCQB: ACMIF) (FSE: 0VJ0) ("Allied" or the "Company") is pleased to report drilling has intersected over 200 metres of breccia-hosted tungsten mineralization at the newly defined Venise Breccia target within its 100%-owned Borralha Tungsten Project in northern Portugal. In particular, ongoing drilling at a newly defined target within the historically documented Venise Breccia at the Borralha Tungsten Project has intersected zones of hydrothermal alteration and quartz-sulphide veining containing visible wolframite, molybdenite and chalcopyrite.

"These initial results bode very well for our fully funded drilling campaign at the Borralha Project. At the Venise target, we have identified significant mineralization at a second Breccia complex to add to the previously discovered Santa Helena Breccia," commented Roy Bonnell, Chief Executive Officer of the Company. "We are encouraged by these early results and continue to believe the Borralha Project is a world-class tungsten deposit with the possibility of being a meaningful new supply of tungsten in a world where pricing is above U.S.$3,000 per mtu [Source: Fastmarkets; April 3, 2026]."

These initial results represent an important step in evaluating the potential of previously underexplored breccia-hosted mineralization systems at Borralha, located approximately 400 metres from the Santa Helena Breccia deposit that underpins the Company's recent initial Preliminary Economic Assessment of the Borralha Tungsten Project ("PEA") announced first on March 2, 2026 and again with more information on March 10, 2026. The identification of visible tungsten mineralization supports the Company's strategy to expand its resource base and reinforces the potential for additional breccia-hosted mineralization within the broader project area. While these observations are encouraging, further drilling and analytical results are required to confirm the scale and continuity of mineralization. This new target supports the Company's strategy to expand the project's resource base and reinforces the Borralha Project's potential as a district-scale tungsten system of strategic importance to European and NATO-aligned supply chains.

The Venise Breccia is not included in the Company's current mineral resource estimate ("MRE") or the PEA mine plan. The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be classified as mineral reserves, and there is no certainty that the PEA will be realized. Drilling remains in progress and is advancing toward the interpreted central portion of the breccia body. For more information on the MRE, please see the Company's news release dated November 19, 2026. For the most recent information on the PEA, please see the Company's news release dated March 10, 2026.

Roy Bonnell, CEO & Director of Allied, commented: "Intersecting visible tungsten mineralization within the historically documented Venise Breccia represents a significant step in validating the broader breccia-hosted potential at the Borralha Project. Located approximately 400 metres from the Santa Helena Breccia deposit, which underpins our recently announced initial PEA, this result reinforces our view that the Borralha Project hosts multiple breccia systems capable of supporting meaningful resource growth and mine life extension.

While these are early-stage observations, the scale and continuity of alteration and mineralization encountered to date are highly encouraging and support our strategy of systematically evaluating historically recognized but underexplored targets using modern exploration techniques. As we advance our fully funded 20,000-metre drill program, we believe the Borralha Project has the potential to evolve into a district-scale tungsten system of strategic importance for Europe and NATO-aligned supply chains."

Geological Context

The Venise Breccia is a new target also located within the Company's 100%-owned Borralha Tungsten Project and is approximately 400 metres northwest to and outside of the planned mining area defined in the Company's initial PEA mine design for the Santa Helena Breccia at Borralha, as described in the Company's most recent new release dated March 10, 2026.

The breccia system at Venise was historically recognized in underground workings and documented in geological studies conducted during the 1970s and 1980s, including academic work describing hydrothermal breccia-hosted tungsten mineralization. However, these zones have not previously been systematically tested using modern exploration methods.

Recent drilling at the Venise Breccia has intersected extensive zones of hydrothermal alteration and quartz-sulphide veining containing visible wolframite tungsten mineralization, locally associated with molybdenite and chalcopyrite. These observations are consistent with historical interpretations and support the Company's geological model of a broader breccia-hosted mineralizing system within the Borralha Project district area.

Historically, mining at the Borralha Project focused primarily on high-grade tungsten veins extracted using underground methods, while breccia-hosted mineralization received comparatively limited attention due to mining and processing constraints at the time. Modern exploration techniques and bulk mining approaches now enable the Company to re-evaluate these systems and assess their potential contribution to future resource growth.

While historical geological descriptions referenced herein have not been verified by the Company's Qualified Person and should not be relied upon, current drilling results provide encouraging indications that these previously underexplored breccia systems may represent a meaningful opportunity for resource expansion within the broader project area.

Drillhole Observations

Preliminary geological logging of the ongoing drillhole has identified:

• zones of strong hydrothermal alteration Quartz-sulphide veining;

• occurrences of visible wolframite, molybdenite and chalcopyrite.

These observations are considered encouraging geological indicators consistent with historical descriptions of mineralization in the area.

Visual appearance of mineralization abundance should not be considered a substitute for laboratory analysis. The presence of visible mineralization is not necessarily indicative of overall grade or width, and no quantitative estimate of grade has been made based on visual observations; pXRF readings are indicative only and are not a substitute for laboratory assays.

Exploration Strategy

The Venise Breccia forms part of Allied's broader strategy to evaluate historically recognized but underexplored breccia-hosted mineralization styles within the Borralha mining concession. The Company believes that combining historical geological knowledge with modern exploration techniques and drilling provides an opportunity to reassess mineralized zones that were not fully evaluated during the historical mining period.

Additional drilling results and laboratory assays from the Venise target will be released once analytical results are received and validated.

Ongoing Growth Strategy

The current initial PEA is based only on the Santa Helena Breccia deposit and an initial 11-year production plan, as described in the Company's most recent news release dated March 10, 2026.

The Company's fully funded 20,000-metre drill program is underway and is targeting:

• expansion of the current mineral resource estimate for the Borralha Project;
• 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 exploration targets and potential implications for mineral resource expansion, conversion, or future mine life extension at the Borralha Project are conceptual in nature. There has been insufficient drilling, geological modelling, and analysis to define a mineral resource at the Venise Breccia, and it is uncertain whether further exploration will result in such targets being delineated as mineral resources. Any reference to possible future resource or mine-life impacts is forward-looking and subject to additional drilling, assay results, and completion of further technical studies.
