Touro Prospect Raises Stakes: Can Alvo Turn Anomalies Into Resources?

Exploration Breakthrough at Touro

Alvo Minerals Limited (ASX – ALV) has unveiled compelling exploration results from its recently discovered Touro Prospect, part of the broader Palma Volcanogenic Massive Sulphide (VMS) copper-zinc project in Tocantins State, Brazil. The company’s latest fieldwork, combining extensive auger drilling and detailed Fixed Loop Electromagnetic (FLEM) surveys, has identified a well-defined mineralised trend extending over one kilometre, rich in zinc, copper, and lead.

With 127 auger holes drilled to an average depth of 14 metres, Alvo’s geochemical analyses using portable X-ray fluorescence (pXRF) have consistently returned anomalous values within a hydrothermally altered felsic schist unit. These results are complemented by multiple gossan occurrences exhibiting zinc grades up to 7.5%, reinforcing the prospect’s potential as a classic VMS-style mineralisation target.

Geophysics Aligns with Geochemistry

The FLEM surveys have been pivotal in delineating conductive zones that coincide with the geochemical anomalies. Two sets of conductor plates were identified – a northern conductor approximately 720 metres long and a southern conductor extending about 1,050 metres. Both are steeply dipping with moderate conductivity and lie at depths ranging from 200 to 250 metres below surface. Notably, the southern conductor extends beyond the currently mapped alteration and geochemical anomaly, prompting plans for further soil and auger sampling to explore this extension.

These geophysical signatures, combined with the geochemical data, provide a robust framework for targeting drill holes, which Alvo is rapidly advancing to maximise the chances of a significant discovery.

Context Within the Palma Project

The Palma Project itself is a substantial district-scale holding, covering over 1,000 square kilometres with more than 70 kilometres of prospective strike. It already hosts three known deposits (C1, C3, and C4) with a combined JORC 2012 Mineral Resource Estimate of 7.6 million tonnes at 2% copper equivalent. These deposits remain open along strike and at depth, indicating further upside potential.

Alvo’s integrated exploration approach; melding geology, geochemistry, and geophysics; has identified over 30 new prospects within Palma, with Touro now elevated as the highest priority drill target. The company’s in-house technical expertise and access to advanced exploration equipment underpin a cost-effective and systematic campaign aimed at resource expansion.

Looking Ahead

Alvo’s Managing Director, Rob Smakman, emphasised the significance of the Touro results, noting the rapid progression towards drill readiness. The company is also conducting ongoing geochemical sampling, geophysical surveys, and geological mapping across Palma, alongside reviews of other projects including the Bluebush and Ipora Rare Earth Elements projects.

With drilling imminent, the market will be watching closely for confirmation of mineralisation at Touro, which could materially enhance the value proposition of the Palma Project and Alvo’s broader portfolio in Brazil.
