Allied Critical Metals Expands Santa Helena Breccia in Borralha with Long Tungsten Intercepts and Confirms High-Grade Trend

Executive Summary

• Allied Critical Metals Inc. announced significant new reverse circulation (RC) drill results from its Borralha Tungsten Project in Portugal, indicating a larger and higher-grade Santa Helena Breccia complex than previously modeled.
• Key intercepts include 100.0 metres @ 0.21% WO₃ in hole Bo_RC_17/25 and a new northern deep lode identified in hole Bo_RC_22/25, expanding the mineralized footprint west and north of previous high-grade zones.
• The company plans to commence an additional 1,528 metres of drilling in Q4 2025 to further define the resource ahead of an updated Mineral Resource Estimate (MRE) and Preliminary Economic Assessment (PEA).

Key Details

• Bo_RC_17/25 (South Infill):
  • 100.0 metres @ 0.21% WO₃ from 52.0 metres.
  • Included 32.0 metres @ 0.33% WO₃ (Metal Factor 10.6 m%) from 92.0 metres.
  • Included 14.0 metres @ 0.52% WO₃ (Metal Factor 5.2 m%) from 106.0 metres.
  • Included 6.0 metres @ 0.74% WO₃ (Metal Factor 4.4 m%) from 110.0 metres.
• Bo_RC_15/25 (South Infill):
  • 2.0 metres @ 0.97% WO₃ from 164.0 metres.
• Bo_RC_22/25 (South-West Deep Step-Out):
  • 64.0 metres @ 0.12% WO₃ from 284.0 metres.
  • Included 16.0 metres @ 0.21% WO₃ from 316.0 metres.
  • Identified a new northern deep lode, opening a new vector for resource growth.
• Contextual Comparison:
  • Results build on previously released Bo_RC_14/25 (12.0 metres @ 4.27% WO₃ from 252.0 metres, including 6.0 metres @ 8.39% WO₃).
• Future Drilling:
  • Company will commence an additional fully funded 1,528 metre drilling campaign in Q4 2025.
• Market Context:
  • Tungsten price reached a new high of US$550/MTU, a >40% increase over the past four months.
• Technical Interpretation:
  • The Santa Helena Breccia is expanding with broad medium-grade intervals and discrete high-grade intercepts.
  • Priority vectors for follow-up include the west-dip high-grade trend and the northern wider deep lode.
  • Updated MRE targeted for Q4 2025, followed by a PEA.
• QA/QC:
  • Drilling completed using RC; samples taken on 2.0m intervals.
  • Certified Reference Materials (CRMs) and field duplicates inserted at 5% rate.
  • Analysis performed by ALS (Seville, Spain prep; Loughrea, Ireland analysis) using ME-MS81 (ICP-MS) and W-XRF15b for over-limit tungsten.

Notable Quotes

• Roy Bonnell, CEO & Director: "These thick, continuous intervals in the central-south and the new northern deep lode materially expand the working envelope at the Santa Helena Breccia in Borralha. Together with the previously reported ultra-high-grade intercept in Bo_RC_14/25, we see clear evidence of a system that is both bigger and better than we initially assumed."
• João Barros, President & COO: "Tungsten is recognized by the European Union as both a critical and strategic raw material under the CRMA... Our work directly supports the EU target of sourcing at least 10% of its critical raw materials domestically by 2030, while reinforcing Portugal's role as a key contributor to Europe's strategic independence."
• General (Ret.) James A. "Spider" Marks, Director: "Expanding the mineral resource at the Borralha Project is an essential next step in path to fulfilling the immense need in Portugal, the EU, NATO and the United States for tungsten powders, concentrates and other byproducts."
