Allied Critical Metals (CSE:ACM) reports four additional drill holes at its Borralha Project in Portugal continue to intersect broad tungsten mineralisation at the Santa Helena Breccia.
The latest results from holes Bo_14/26, Bo_16/26, Bo_18/26, and Bo_19/26 demonstrate continuity of mineralisation within the current mineral resource envelope, supporting the geological model underpinning the company’s preliminary economic assessment (PEA).
Hole Bo_19/26 returned 25.6m @ 0.25% tungsten trioxide (WO3), while Bo_18/26 intersected 15.8m @ 0.36% WO3. Bo_16/26 delivered 18m @ 0.28% WO3, and Bo_14/26 returned 22m @ 0.23% WO3.
The results follow previously reported hole Bo_13/26, which intersected 81.5m @ 0.22% WO3, including 23.8m @ 0.68% WO3 and 4m @ 2.96% WO3.
CEO Roy Bonnell says the company continues to intersect broad zones of tungsten mineralisation containing ‘higher-grade’ internal intervals.
“[The results] reinforce our geological model and provide the additional technical information required for resource conversion, mine planning, geotechnical engineering and metallurgical work,” Bonnell says.
The drilling demonstrates the mineralisation architecture at Santa Helena, comprising broad mineralised intervals containing narrower ‘higher-grade’ zones.
This geometry aligns with the bulk underground mining approach evaluated in the Borralha PEA.
The company is advancing Borralha on two fronts: development-focused drilling at Santa Helena to de-risk the current PEA case, and district-scale exploration at the newly discovered Venise Breccia, about 400m north-west.
At Venise, the initial discovery hole Bo_BV_01b returned multiple tungsten and molybdenum intervals including 13m at 1.00% WO3, including 3m at 4.15% WO3.
Holes Bo_BV_02b and Bo_BV_04a are complete with assays pending, while drilling continues in Bo_BV_05a and Bo_BV_06b.
The Santa Helena campaign aims to increase confidence in the current mineral resource estimate, support resource conversion and mine planning, and provide geotechnical and metallurgical information for ongoing technical studies.
Holes Bo_23/26 and Bo_26/26 are complete with assays pending. The company expects the program to increase geological and technical information density within Santa Helena while providing data for future feasibility-level studies.
Allied continues to progress towards closing the second tranche of its US$25 million ($35 million) private placement at US$2.05 per share, with the second tranche valued at US$15 million.
Allied Critical Metals is an Canadian explorer advancing a portfolio of tungsten, tin, and polymetallic assets.
