– The first diamond hole drilled at Alvo’s 100% owned Touro Prospect has intercepted massive sulphide mineralization, including copper, at a depth of 13 meters (40 meters below surface).
– Diamond drill hole PDT_117 focused on the downward extension of surface trenching intercepting gossans in the recently announced Trench 2. This mineralization extends over >1 km from the strike at the surface.
– No drilling has occurred on the fixed loop electromagnetic (FLEM) conductors, which start approximately 100 meters deeper than the massive sulfides intercepted in this discovery borehole and provide an exciting deeper target.
– Drilling at Touro continues at hole PDT-118, targeting the downslope extension beneath Trench 3, approximately 500 meters north of PDT-117. Tests are expected within 6-8 weeks.
Rob Smakman, Managing Director of Alvo, said:
“We are pleased to announce this discovery at Touro from the very first drill hole aimed at systematically tracking a mineralized zone of over 1 km with extensive gossamer outcrops. Drilling is the ultimate test and intersecting such broad, shallow and potentially high-grade mineralization is an exciting outcome for the first ever drill hole completed on this new target.
The scale of the Touro project is impressive: it’s over 1 km long and housed in a unit mapped to about 40 meters wide, and because the FLEM slabs extend well below the surface, we can drill here for a while – just to find the edges. We look forward to taking the samples to the laboratory for final quality testing and confirming these impressive images.”
Touro VMS Prospect
Touro is a recently discovered VMS prospect with a well-defined mineralized trend extending over 1,100 m (Figure 2*). The mineralization contains numerous surface gossans containing up to 7.5% Zn, 0.2% Cu and 1.0% Pb and is supported by coincidental soil and auger geochemical anomalies, trench sampling and 2 large sets of fixed loop electromagnetic (FLEM) conductors.
Geological mapping at the surface and in the trenches identified mineralized gossans (including the zinc-bearing alteration mineral gahnite) within a hydrothermally altered contact zone located between mafic and felsic rocks.
First drill hole PDT-117, targeting the massive, semi-massive and disseminated subsurface mineralized gossans, mapped in Trench 2 (see Figures 2 and 3*). During drilling, a non-oxidized (fresh rock) containing massive, semi-massive and disseminated sulphides was intercepted from 51.5 m to 64.6 m, with a borehole width of 13.1 m.
Importantly, the sulfides captured in the hole include the copper-bearing mineral chalcopyrite and the zinc-bearing mineral sphalerite, along with the iron-bearing minerals pyrite and pyrrhotite (both are unmineralized). Tests are expected in approximately 6-8 weeks. A summary description is included in Table 1* in the link below.
The rig has now been moved to the second hole at Touro (PDT-118), targeting the downslope extensions of the gossans mapped in Trench 3, approximately 500 meters north of PDT-117 (see Figure 2*). A downhole electromagnetic survey (DHEM) will be conducted on PDT-117 in the coming days to test for conductors near holes not found in previous FLEM surveys.
Results from detailed FLEM surveys across Touro revealed an extensive anomaly, aligned and coincident with the soil/jack anomaly described above. Inversion of this FLEM anomaly has highlighted two sets of conductor plates, one set to the north and one set to the south, extending beyond the geological/geochemical anomaly. Conductor plates are tabular zones, interpreted as zones of relatively higher conductivity than the edges. Massive sulfides are generally highly conductive (especially chalcopyrite and pyrrhotite).
Hole PDT-117 did not target these slabs because they are deeper than the target, but they will be tested in the coming weeks.
The Palma Project
Alvo’s 100% owned Palma Cu-Zn project (see Figure 5*) hosts a total MRE across three deposits of 7.6 Mt @ 2.02% CuEq (or 6.2% ZnEq) for 153kt contained CuEq tonnes (0.7% Cu, 3.4% Zn, 0.6% Pb, 16 g/t Ag and 0.03 g/t Au), demonstrating the potential for Palma to develop into an important VMS district.
All deposits in Palma remain open at strike and at depth and have potential to expand and improve with additional drilling, geological reinterpretation, metallurgy and engineering studies.
The fieldwork carried out in 2025 included drilling, soil sampling, geophysical surveys and geological mapping throughout Palma, where Alvo owns more than 1,000 km2 of land and more than 80 km of the future geological package. Palma hosts VMS style mineralization, where multiple deposits can typically form in similar geological settings. Alvo’s exploration team has defined and is currently prioritizing more than 30 new prospects.
The ongoing exploration in Palma aims to integrate the disciplines of geology, geochemistry and geophysics across the different prospects, gradually refining them until the most prospective are ready to be drilled. Alvo is unique among its peers in that it has an experienced in-house team with access to cutting-edge equipment, allowing exploration to continue at a low cost.

Alvo Minerals (ASX:ALV,OTC:ALVMF) (OTCMKTS:ALVMF) is an active Australian mineral exploration company, with an established exploration base in central Brazil. The company was founded to explore base and precious metals and search for high-quality copper and zinc at the Palma Copper Zinc Project in the state of Tocantins, Brazil. Palma has a JORC 2012 mineral resource estimate of 7.6 Mt @ 2.0% CuEq or 6.2% ZnEq (0.7% Cu, 3.4% Zn, 0.6% Pb & 16g/t Ag and 0.03g/t Au). This MRE is categorized as indicated: 3.3 Mt @ 2.3% CuEq or 6.9% ZnEq and derived: 4.3 Mt @ 1.8% CuEq or 5.6% ZnEq.
Alvo is also investigating Rare Earth Elements (REE) in its two Ionic Clay REE projects near its exploration base in Central Brazil – Bluebush and Ipora. Alvo’s strategic intent is to aggressively explore and realize growth through discovery, leveraging management’s extensive track record in Brazil. The exploration strategy consists of three phases: discovery, expansion and upgrade. Alvo is committed to fostering the best relationships with stakeholders and supporting the local communities in which it operates.
