Critical minerals explorer Alvo Minerals (ASX:ALV) has commenced a significant diamond drilling program at its Palma Cu-Zn VMS Project in Central Brazil.

The drilling, spanning up to 5,000 meters, aims to explore three high-priority prospects within the project - Urubu, Anta, and C4-NE.

The company says the targets were refined through comprehensive multi-disciplinary exploration techniques, indicating strong potential for VMS mineralisation.

“This maiden drill program is our most exciting to date, as we’ll be able to test a pipeline of untested VMS prospects – the culmination of countless hours of detailed data collection and interpretation to refine and priorities the large number of targets across the >70km of prospective strike at Palma,” said Managing Director of Alvo Minerals Rob Smakman.

With an Inferred Mineral Resource Estimate of 4.6Mt at grades of 1.0% Cu, 3.9% Zn, 0.4% Pb, & 20g/t Ag, the company is encouraged by promising early results.

The exploration team is continuing its work across the belt while drilling is in progress, with further investigations aimed at bringing additional prospects to drill-ready status.

In addition to the Palma Project, Alvo Minerals is exploring for Rare Earth Elements (REE) at the Bluebush Ionic Clay REE Project and the Ipora REE Project in Central Brazil.
