Allied Critical Metals Expands Santa Helena Breccia with 6.0 Metres of 1.02% WO3 Intercept at Borralha

Executive Summary

• Allied Critical Metals announced significant assay results from two 2025 RC drill holes (Bo_RC_27/25 and Bo_RC_28/25) at the Borralha Tungsten Project, showing strong continuity and higher‑grade tungsten mineralization.
• Hole Bo_RC_27/25 returned a 46.0 m interval averaging 0.22 % WO₃ (including 22.0 m @ 0.35 % WO₃ and a standout 6.0 m @ 1.02 % WO₃), confirming expansion of the north‑western dip zone of the Santa Helena Breccia.
• Hole Bo_RC_28/25 delivered multiple high‑grade lenses (8.0 m @ 0.68 % WO₃, 2.0 m @ 0.94 % WO₃, and an additional 4.0 m @ 0.42 % WO₃), validating up‑dip continuity toward surface and supporting upcoming MRE and PEA work.

Key Details

• Drill Hole Bo_RC_27/25 – 46.0 m (33.1 m true width) @ 0.22 % WO₃ from 204.0 m depth
• Includes 22.0 m (15.8 m TW) @ 0.35 % WO₃ from 228.0 m
• Includes 6.0 m (4.3 m TW) @ 1.02 % WO₃ from 228.0 m
• Drill Hole Bo_RC_28/25 – 8.0 m (5.4 m TW) @ 0.68 % WO₃ from 90.0 m depth
• Includes 2.0 m (1.4 m TW) @ 0.94 % WO₃ from 96.0 m
• Additional 4.0 m (2.7 m TW) @ 0.42 % WO₃ from 210.0 m
• Both holes confirm expansion of the north‑western dip area and up‑dip continuity of high‑grade tungsten mineralization within the Santa Helena Breccia.
• To date, 4,210 m of RC drilling completed out of a planned 5,625 m Phase 1 campaign; remaining assays pending.
• Results will feed into an updated Mineral Resource Estimate (expected Q4 2025) and a Preliminary Economic Assessment scheduled for Q1 2026.
• Program objectives: expand/upgrade NI 43‑101 MRE, develop robust PEA, support underground mine design, and integrate with ongoing EIA review.
• Sampling & QA/QC: RC drilling; 2 m interval sampling; CRMs and field duplicates inserted at 5% frequency; analysis performed by ALS (Seville & Loughrea) using ME‑MS81 ICP‑MS method, with over‑limit tungsten re‑assayed via W‑XRF15b.
• Qualified Person: Vítor Arezes, BSc, MIMMM (QMR), Vice‑President Exploration, reviewed and approved technical information.

Notable Quotes

“Borralha continues to exceed expectations… Hole Bo_RC_27/25 delivered one of the most continuous and grade‑consistent intercepts drilled to date… Bo_RC_28/25 confirmed up‑dip continuity of high‑grade mineralization toward surface, an encouraging indicator for potential shallow extraction scenarios.” – Roy Bonnell, CEO & Director
