Allied Critical Metals Delivers Strong First Results at Santa Helena with 23.8 Metres of 0.68% WO3; Provides Borralha Project Update

First drill hole of 2026 supports view that the Santa Helena deposit underpins the Borralha Project's recently completed Preliminary Economic Assessment ("PEA") 1 . 23.8 metres grading 0.68% WO₃ from 24.0 m (estimated true width), including 4.0 metres grading 2.96% WO₃ , from 44.0 m, confirming broad zones of high-grade tungsten mineralization. Wide mineralized corridor of 57.6 metres grading 0.30% WO₃ from 24.0 m (estimated true width) demonstrates the continuity of the Santa Helena Breccia bulk mineralized system. 20,000 metre drilling campaign focused on the Borralha Project is accelerating , with six rigs operating and a seventh arriving shortly. While Santa Helena drilling is advancing the existing development project, additional drilling continues concurrently at the newly discovered Venise Breccia , offering significant exploration upside beyond the current estimated resources and PEA. The Company expects to provide additional assay results from both the Santa Helena development drilling program and the ongoing Venise exploration campaign as they become available. Vancouver, British Columbia--(Newsfile Corp. - July 16, 2026) - Allied Critical Metals Inc. (CSE: ACM) (OTCQB: ACMIF) (FSE: 0VJ0) ("Allied" or the "Company") is pleased to announce the first assay results from its 2026 drilling campaign at the Santa Helena Breccia, delivering another important milestone to advance the Borralha Tungsten Project in northern Portugal (the " Borralha Property " or the " Borralha Project ") while continuing to unlock the district's broader exploration potential. The first drill hole of the current campaign, Bo_13/26 , successfully intersected broad tungsten mineralization consistent with the current geological and mineral resource model. The results continue to demonstrate the continuity of the Santa Helena Breccia while providing important information for ongoing resource conversion, mine planning, geotechnical engineering and metallurgical variability studies. Drill hole Bo_13/26 returned multiple significant tungsten intervals: 81.5 metres grading 0.22% WO₃ including 57.6 metres grading 0.30% WO₃ including 23.8 metres grading 0.68% WO₃ including 4.0 metres grading 2.96% WO₃ The higher-grade tungsten occurs within broad mineralized corridors that are expected to support the Borralha Project's planned bulk underground mining approach, an important factor underpinning the economics outlined in the Company's recent preliminary economic assessment of the Borralha Project (the "PEA ") 1 entitled "NI 43-101 Technical Report Preliminary Economic Assessment, Borralha Tungsten Project, Parish of Salto, District of Vila Real, Portugal", dated effective April 14, 2026, which is published on the Company's website at www.alliedcritical.com and under its profile on SEDAR+ at www.sedarplus.ca . "The first assay results from our 2026 Santa Helena drilling campaign continue to validate the geological and mineralization model that underpins the Borralha Preliminary Economic Assessment," said Roy Bonnell, CEO and Director of Allied Critical Metals . "The recent Venise Breccia discovery has the potential for district-scale growth at Borralha, and these results shows that the Santa Helena Breccia remains the foundation of our development strategy. The results confirm the continuity of the broad mineralized corridors that support our planned bulk underground mining approach while providing critical geological, geotechnical and metallurgical information required to advance the Project toward future feasibility studies. With six drill rigs currently operating and a seventh expected shortly, we are executing the largest drilling campaign in Borralha's recent history. Our strategy is twofold: continue expanding the long-term potential of the district through exploration at Venise while simultaneously increasing confidence in the Santa Helena Mineral Resource through infill, technical and engineering dri...
