Highlights 

  • Bo_RC_25 extends ultra high-grade tungsten zone with 4.0 m @ 3.72% WO3. 
  • Phase 1 drilling completes 4,210 m, contributing to upcoming MRE and PEA updates. 
  • Tungsten prices hit USD 700/MTU APT amid rising global demand. 

Allied Critical Metals Inc. (CSE:ACM) has released updated assay results from its 2025 Reverse Circulation drilling program at the Borralha Tungsten Project in northern Portugal. The latest data verify and expand the ultra-high-grade tungsten zone originally identified in Bo_RC_14, confirming continuity within the Santa Helena Breccia mineralized system. 

Hole Bo_RC_25/25 delivered the most significant results, intersecting 18.0 m @ 0.85% WO3 from 270.0 m, including 4.0 m @ 3.72% WO3. Additional holes, Bo_RC_20/25 and Bo_RC_29/25, also returned substantial tungsten grades, validating mineralization along the western and northwestern dips of the SHB. 

Drill Hole Highlights 

Bo_RC_25/25: 

  • 18.0 m @ 0.85% WO3 from 270.0 m 
  • Includes 4.0 m @ 3.72% WO3 from 270.0 m 
  • Extends the high-grade zone reported in Bo_RC_14 

Bo_RC_20/25: 

  • 18.0 m (16.4 m TW) @ 0.29% WO3 from 170.0 m 
  • Includes 6.0 m (5.5 m TW) @ 0.76% WO3 
  • Confirms high-grade lenses within the upper SHB flank 

Bo_RC_29/25: 

  • 10.0 m (7.9 m TW) @ 0.27% WO3 from 96.0 m 
  • Includes 4.0 m (3.2 m TW) @ 0.45% WO3 
  • Supports westward continuity along strike 

Roy Bonnell, CEO & Director, stated: 
"Borralha continues to outperform expectations. The confirmation of the very high-grade tungsten zone from Bo_RC_14 by Bo_RC_25 underscores the strength and continuity of the Santa Helena Breccia system on the Borralha property. These new results further demonstrate the potential for significant resource expansion and underscore Borralha's importance as a cornerstone tungsten asset for Allied and for Portugal." 

Drilling Program and Geological Overview 

To date, 4,210 m of the planned 5,625-m Phase 1 campaign have been drilled. The program is focused on expanding and updating the current NI 43-101 Mineral Resource Estimate and providing data for the upcoming Preliminary Economic Assessment. 

Holes Bo_RC_25/25, Bo_RC_20/25, and Bo_RC_29/25 outline a continuous, steeply dipping mineralized backbone that remains open along strike and at depth. These results confirm the grade, continuity, and structural orientation of the SHB and will feed into both the MRE and PEA. 

Tungsten Market Update 

Tungsten prices recently reached USD 700/MTU APT, up roughly 70% over the past six months, driven by growing global demand and constrained supply for critical raw materials.
