Alvo Minerals sharpens drill targets at Touro prospect in Brazil after promising trenching results

Alvo Minerals (ASX:ALV) refines drill targets at the Touro prospect in Brazil after trenching confirms near-surface copper, zinc, and lead mineralisation along a 1.1km corridor.

Alvo Minerals (ASX:ALV) has refined its exploration focus at the Touro prospect in central Brazil after trenching confirmed near-surface copper, zinc, and lead mineralisation extending across a 1.1km corridor.

The company completed three trenches across the mineralised zone, returning notable results including 2.4 metres @ 2,559ppm zinc, 756ppm copper, and 447ppm lead, and 12.6 metres @ 2,028ppm zinc, 272ppm copper, and 374ppm lead.

Alvo is now preparing to test deeper targets, where modelling indicates two significant fixed-loop electromagnetic (FLEM) conductors sit directly beneath the trenching area.

Confidence grows ahead of drilling

Managing Director Rob Smakman said the results reinforce the team’s confidence in the Touro prospect and suggest the potential for a new volcanic massive sulphide (VMS) system within the Palma district.

“The grades of the oxide are generally lower than in fresh rock – however, we have never seen grades this high in gossan before, even at C3, our highest-grade deposit,” Smakman said.

“We are excited about getting the drill rig positioned over Touro.”

The northern FLEM plate measures approximately 720 metres by 320 metres, while the southern plate extends about 1 kilometre by 400 metres. Both targets will be refined through additional soil and auger sampling before the start of drilling.

Expanding exploration across the Palma corridor

In parallel, Alvo is mobilising rigs across the broader Palma corridor, an underexplored region hosting more than 30 identified prospects. The company’s goal is to uncover new VMS discoveries capable of supporting future resource growth and scale.

Alvo Minerals is an active critical minerals explorer with a well-established exploration base in central Brazil, targeting copper, zinc, and other base metals within one of the country’s most prospective mineral belts.
