Alvo Minerals (ASX:ALV) has tightened its targeting at the Touro prospect in Brazil, after trenching confirmed near-surface copper, zinc and lead mineralisation along a 1.1km corridor.
Three trenches were completed across the mineralised target, with some results returning 2.4m @ 2,559 parts per million (ppm) zinc, 756ppm copper, and 447ppm lead; 12.6m @ 2,028ppm zinc, 272ppm copper, and 374ppm lead.
Alvo is preparing to test deeper targets where modelling indicates two substantial fixed-loop electromagnetic (FLEM) plates sit beneath the trenching.
Managing Director Rob Smakman says the results strengthen confidence ahead of drilling and highlight the potential for a fresh volcanic massive sulphide (VMS) position within the Palma district.
“The grades of the oxide are generally lower than the fresh rock – however we have never seen grades this high in gossan before – even at C3, our highest-grade deposit,” Smakman says.
“We are excited about getting the drill rig positioned over Touro.”
The northern fixed-loop electromagnetic plate measures around 720m by 320m, while the southern plate extends roughly 1km by 400m. Both will be refined with additional soil and auger sampling before drilling.
Alvo is also mobilising rigs across the wider Palma corridor, where more than 30 prospects have been identified, as the company works to establish new VMS discoveries capable of adding future resource scale.
