Allied Critical Metals (CSE:ACM) reports ‘strong’ first results from its 2026 drilling campaign at the Santa Helena breccia, part of the Borralha Tungsten Project in Portugal.
Drilling intersected 23.8m @ 0.68% tungsten trioxide (WO₃) from 24.0m, including 4.0m @ 2.96% WO₃ from 44.0m at the Borralha Tungsten Project. A wider mineralised corridor returned 57.6m @ 0.30% WO₃ from 24.0m.
The first drill hole of the current campaign intersected broad tungsten mineralisation, returning multiple significant intervals including 81.5m @ 0.22% WO₃.
CEO Roy Bonnell says the first assay results from Allied’s 2026 Santa Helena drilling campaign continue to validate the geological and mineralisation model that underpins the Borralha preliminary economic assessment.
“The recent Venise breccia discovery has the potential for district-scale growth at Borralha, and these results show that the Santa Helena breccia remains the foundation of our development strategy,” Bonnell says.
“The results confirm the continuity of the broad mineralised corridors that support our planned bulk underground mining approach while providing critical geological, geotechnical, and metallurgical information required to advance the project toward future feasibility studies.”
Allied currently has six rigs operating in light of its 20,000m drilling program, with a seventh expected shortly.
The campaign focuses on supporting project advancement through resource conversion, geological model confirmation, geotechnical characterisation for underground mine design, and metallurgical variability sampling.
The Borralha Project represents one of the largest undeveloped tungsten resources within the European Union. The company completed a preliminary economic assessment in April 2026.
Allied Critical Metals is focused on the advancement and revitalisation of its fully owned Borralha and Vila Verde tungsten projects in northern Portugal.
