Allied Critical drills 10 m of 1.11% WO3 at Borralha

Executive Summary

• Allied Critical Metals Inc. released new assay results from its reverse circulation drill program at the 100%-owned Borralha tungsten project in northern Portugal, highlighting significant high-grade intercepts that confirm continuity of mineralization.
• Hole Bo-RC-16 delivered one of the longest and highest-grade intervals to date at the Santa Helena breccia, including 10.0 meters of 1.11% WO3, supporting the company's goal of unlocking significant resource growth ahead of a Preliminary Economic Assessment (PEA).
• The Phase 1 drilling campaign has concluded with 4,210 meters drilled against a planned 5,625 meters, with further results expected in the coming weeks to support an updated National Instrument 43-101 Mineral Resource Estimate (MRE) expected in Q4 2025.

Key Details

• Bo-RC-16 Highlights:
  • 90.0 meters of 0.24% WO3 from 60.0 meters.
  • Included 40.0 meters of 0.40% WO3 from 100.0 meters.
  • Included 10.0 meters of 1.11% WO3 from 100.0 meters, which itself included 6.0 meters of 1.78% WO3.
  • Additional intercept: 12.0 meters of 0.33% copper, 25 g/t silver, and 138 ppm molybdenum from 188.0 meters.
• Bo-RC-18 Highlights:
  • 74.0 meters of 0.12% WO3 from 154.0 meters.
  • Included 14.0 meters of 0.15% WO3 from 192.0 meters.
  • Included 2.0 meters of 0.35% WO3 from 226.0 meters.
• Bo-RC-19 Highlights:
  • 4.0 meters of 0.19% WO3 from 124.0 meters.
• Drilling Progress:
  • Phase 1 campaign is complete with 4,210 meters drilled (of 5,625 meters planned).
  • Focus included expanding/upgrading the NI 43-101 MRE, developing a PEA, and supporting underground mine design.
• Geological Context:
  • Bo-RC-16 strengthened resource resolution at the western dip edge of the central-south backbone, returning higher and more consistent grades than anticipated.
  • Bo-RC-18 and Bo-RC-19 targeted the transition gap between the central-south high-grade backbone and a north-dipping large medium-grade lode, demonstrating continuity in an area historically interpreted as lower grade.
• Methodology:
  • Drilling completed using reverse circulation (RC).
  • Samples taken on 2.0-meter intervals with 1.0-meter reject splits.
  • Quality Assurance/Quality Control (QA/QC) included Certified Reference Materials (CRMs) and field duplicates at a rate of 5% (one in 20 samples).
  • Analysis performed by ALS (Seville, Spain for prep; Loughrea, Ireland for analysis) using ME-MS81 (ICP-MS) and ME-4ACD81 (four-acid digestion).

Notable Quotes

• "Borralha continues to surprise us on the upside. Bo-RC-16 has delivered one of the strongest intercepts ever drilled on the project, expanding the high-grade central-south mineralization. Meanwhile, Bo-RC-18 and Bo-RC-19 has successfully demonstrated mineralization continuity in what was considered a weaker zone. Together, these results confirm both scale and grade potential as we advance towards our updated MRE and PEA." — Roy Bonnell, CEO and Director
