PVW Completes 1,477m Drilling at Capão Bonito with 89% Rare Earth Leach Extraction

Hydraulic Auger Drilling Advances Rare Earth Exploration

PVW Resources Ltd (ASX – PVW) has reported significant progress in its Brazilian Southeast Hub rare earth projects, notably at the Capão Bonito site. The company completed a comprehensive hydraulic auger drilling program, delivering 98 holes for a total of 1,477 metres. This latest campaign extended the average drilling depth from 13 to 19 metres, with some holes reaching 30 metres, allowing for a better understanding of the mineralised weathering profile and the continuity of high-grade zones.

The adoption of hydraulic auger drilling technology has been a game changer for PVW, enabling faster and deeper sampling with improved sample recovery. This method has reduced operational time and costs, positioning the company well for the next phase of infill and resource-definition drilling.

Outstanding Metallurgical Potential Confirmed

Early leach testing results have been particularly encouraging, with ammonium sulphate leach extractions reaching up to 89%. These findings validate the Ionic Adsorption Clay (IAC) mineralisation style at Capão Bonito and highlight the strong metallurgical potential of the deposit. The high leach recoveries suggest that the rare earth elements can be extracted through low-impact, cost-effective processes, which is a critical factor for future development.

While assay results from the recent drilling are still pending, the initial data points to several priority zones within the Capão Bonito project, including the Southwest, East, and North-Central sectors. These areas exhibit promising grade continuity and metallurgical favourability, guiding PVW’s targeted infill and step-out drilling plans.

Broader Southeast Hub Exploration Progress

Beyond Capão Bonito, PVW has also advanced reconnaissance drilling at its other Southeast Hub projects; Sguario, Cerro Azul, and Carambeí. These programs involved hydraulic auger drilling to test extensions of known mineralisation and new structural targets, with assay results awaited. The projects benefit from favourable geology and strong infrastructure, including proximity to major ports, which enhances their strategic value.

PVW’s management emphasizes a systematic approach to exploration, integrating geological, geochemical, and metallurgical data to refine exploration targets and support future resource estimation. The company’s dual focus on rare earth elements and precious metals in Brazil leverages its in-country expertise and infrastructure, aiming to unlock significant shareholder value.

Looking Ahead – Resource Definition and Regional Expansion

PVW’s immediate priorities include receiving and interpreting the pending assay and metallurgical results, followed by targeted infill drilling to confirm resource continuity and grade distribution. The company plans to define an Exploration Target at Capão Bonito, laying the groundwork for a systematic core drilling program aligned with JORC standards.

Additionally, PVW intends to expand its regional exploration footprint within the Southeast Hub, identifying new IAC-style rare earth targets to build a pipeline of prospects. This strategic progression underscores PVW’s commitment to advancing its Brazilian rare earth portfolio towards scalable resource development.
