Allied Critical Metals Intersects 12 Metres of 4.27% Tungsten (WO3) Incl. 6 Metres of 8.39% Tungsten (WO3) at Its 100% Owned Borralha Tungsten Project in Northern Portugal

Executive Summary

• Allied Critical Metals announced high-grade tungsten drill results from hole Bo_RC_14/25 at its Borralha Project in Portugal, intersecting 12.0 metres @ 4.27% WO3, including a high-grade core of 6.0 metres @ 8.39% WO3.
• The company has completed over 2,500 metres of drilling across nine holes, with the remaining 1,600 metres of the current 4,200-metre campaign underway and an additional fully funded 1,528 metres planned for Q4 2025.
• The release highlights a strategic context of rising tungsten prices (reaching $545 USD/MTU) and positions the Borralha wolframite mineralization as a key Western supply source, supporting upcoming Mineral Resource Estimates and a Preliminary Economic Assessment.

Key Details

• Drill Hole Bo_RC_14/25 Intercepts:
  • 12.0 metres @ 4.27% WO3 from 252.00 metres downhole.
  • Includes 6.0 metres @ 8.39% WO3.
  • Mineralization identified as high-quality wolframite within a controlled high-grade breccia corridor.
• Drilling Campaign Status:
  • Total planned Phase 1 campaign: 4,200 metres.
  • Completed as of July 30, 2025: ~2,500 metres across 9 holes.
  • Remaining in current campaign: 1,600 metres.
  • Additional planned drilling: 1,528 metres fully funded for Q4 2025.
  • Operations resumed September 1, 2025, with two rigs active after an August pause for fire safety.
• Other Drill Holes Status:
  • Bo_RC_15/25: West deep step-out; breccia and wolframite visually confirmed; assays ongoing.
  • Bo_RC_16/25 & Bo_RC_17/25: Infill holes for resource resolution; breccia with visible mineralization observed; pending assays.
  • Bo_RC_18/25, Bo_RC_19/25, & Bo_RC_26/25: Infill holes in central/lower grade areas; visible mineralization identified; pending assays.
  • Bo_RC_21/25 & Bo_RC_22/25: Step-out holes for potential new high-grade corridor; continuous breccia and visible sulphides/polymetallic indicators (wolframite/chalcopyrite) found; pending assays.
• Technical & Processing Context:
  • Focus on wolframite mineralization, which allows for more efficient processing via gravity and magnetic separation compared to scheelite, resulting in lower costs and higher recoveries.
  • Samples analyzed by ALS Laboratories using ME-MS81 method (ICP-MS) and ME-XRF15c for over-limit tungsten.
• Corporate Updates:
  • Colin Padget resigned as director effective September 1, 2025, but remains as an advisor.
  • Grant of stock options and RSUs previously announced on September 2, 2025, has been postponed to a future date.
• Project Milestones:
  • Updated Mineral Resource Estimate (MRE) anticipated in Q4 2025.
  • Preliminary Economic Assessment (PEA) for a large-scale processing facility targeted for completion later in 2025.
  • Environmental Impact Assessment (EIA) formal response expected Q3 2025, with final decision anticipated Q4 2025 or early Q1 2026.

Notable Quotes

• "These initial assay results are a major step forward for the Borralha Project and a clear validation of our geological model. The exceptional tungsten grades intersected in Bo_RC_14/25 place Borralha among the most exciting undeveloped critical mineral assets in Europe." — Roy Bonnell, CEO & Director
