Alvo Minerals Limited (ASX: ALV) ('Alvo' or 'the Company') is pleased to update shareholders on new results from trenching at Touro Prospect at the Palma Copper Zinc Projectin Brazil.
The trenching was designed to expose the geology across the alteration and gossan zones which extend on surface for over 1,100m and averages 40m wide.
Rob Smakman, Alvo's Managing Director commented: 'Our newly defined Touro target keeps charging ahead and these trench results provide strong evidence of thick mineralised zones, hosted within the hydrothermally altered unit. If these gossans are oxidised massive sulphides, they are the surficial expression of the VMS mineralisation we are actively exploring for at the Palma Project. 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. We are excited about getting the drill rig positioned over Touro.'
Touro VMS Prospect
Touro is a recently discovered VMS prospect featuring a well-defined mineralised trend extending for over 1,100m. The mineralisation contains numerous gossans on surface containing up to 7.5% Zn, 0.2% Cu, and 1.0% Pb4 and is supported by coincidence soil and auger geochemical anomalies along with 2 large FLEM conductors. Geological mapping encountered mineralised gossans (which included the zinc bearing alteration mineral gahnite) within a hydrothermally altered contact zone located between mafic and felsic rocks. Three trenches were completed at Touro perpendicular to the hydrothermally altered unit which is coincident with the geochemical anomaly and the northern FLEM anomaly. The trenches were dug to better understand the 'close to surface' geological context, where mapping identified massive, semimassive and disseminated gossan material, indicative of potential VMS style mineralisation. Also identified was the structural context, which supports drill planning.
The Palma Project
Alvo's 100% owned Palma Cu-Zn Project hosts a Total MRE5 across three deposits of 7.6Mt @ 2.02% CuEq (or 6.2% ZnEq) for 153kt of contained CuEq tonnes (0.7% Cu, 3.4% Zn, 0.6% Pb, 16g/t Ag and 0.03 g/t Au), demonstrating the potential for Palma to emerge as a significant VMS district. All deposits at Palma remain open along strike and at depth and have potential to expand and upgrade with additional drilling, geological re-interpretation, metallurgy and engineering studies. Field work conducted throughout 2025 has comprised auger drilling, soil sampling, geophysical surveys and geological mapping across Palma where Alvo has >1,000km2 of ground under tenure and >80km of strike of the prospective geological package. Palma hosts VMS style mineralisation where multiple deposits can typically form in similar geological settings. Alvo's exploration team have defined and are currently prioritising over 30 new Prospects. Ongoing exploration at Palma is designed to integrate the disciplines of geology, geochemistry and geophysics at the different prospects, gradually refining them until the most prospective are ready to be drilled.
