Allied Critical Metals Inc. (CSE: ACM; OTCQB: ACMIF; FSE: 0VJ0) has released highlighted intercepts from its 2023–2024 drilling at the 100%-owned Borralha Tungsten Project in northern Portugal, ahead of an updated Mineral Resource Report targeted for Q4 2025. The results—previously included in the company’s July 31, 2024 NI 43-101 technical report—cover 3,685 m across 16 holes focused on the Santa Helena Breccia (SHB).
Notable intercepts include:
-
Bo_Met_01: 106.0 m (true width 80.4 m) @ 0.21% WO₃ from 60.0 m, incl. 5.0 m (3.8 m true) @ 0.60% WO₃.
-
Bo_Met_02a: 23.0 m (21.9 m true) @ 0.53% WO₃ from 62.0 m.
-
Bo_RC_02: 108.0 m (98.3 m true) @ 0.22% WO₃ from 26.0 m, incl. 16.0 m (14.6 m true) @ 0.63% WO₃.
-
Bo_RC_11: 38.0 m (29.5 m true) @ 0.56% WO₃ from 112.0 m, incl. 10.0 m (7.8 m true) @ 1.75% WO₃.
-
Bo_RC_12: 20.0 m (19.3 m true) @ 0.50% WO₃ from 82.0 m, incl. 12.0 m (11.6 m true) @ 0.78% WO₃; plus 2.0 m (1.8 m true) @ 5.79% WO₃ from 182.0 m and 12.0 m (10.8 m true) @ 0.40% WO₃ from 238.0 m, incl. 4.0 m (3.6 m true) @ 1.12% WO₃.
The company also highlighted a Sept 4, 2025 intercept at Borralha of 12.0 m @ 4.27% WO₃, including 6.0 m @ 8.39% WO₃ from 252.0 m downhole—one of the highest-grade tungsten hits reported in Western exploration, particularly for wolframite mineralization.
Allied invested ~US$4.1 million in 2023–2024 exploration and is continuing 2025 drilling at SHB, with ~5,700 m from this year expected in the upcoming resource update. Current NI 43-101 resources at Borralha stand at 4.98 Mt @ 0.22% WO₃ (Indicated) and 7.01 Mt @ 0.20% WO₃ (Inferred). Management positions Borralha as a significant undeveloped tungsten asset in the West, potentially offering near-term supply outside China and Russia.
QA/QC protocols included ALS sample preparation (Seville) and ICP-MS analyses (Loughrea), insertion of certified reference materials and duplicates at 5% each, and re-analysis of over-limit tungsten via W-XRF. The program comprised PQ diamond and RC drilling; core from metallurgical holes was split between Wardell Armstrong (met testwork) and ALS (assay). The scientific and technical information was approved by Qualified Person Vítor Arezes, BSc, MIMMM (QMR), VP Exploration.
Allied emphasized the processing advantages of wolframite over scheelite—gravity/magnetic separation with lower capex/opex and higher recoveries—supporting project economics at grades typical of Western benchmarks. The company underscores strategic alignment with NATO-friendly supply chains amid concentrated global tungsten production.
