Enova Faces Challenges in Scaling East Salinas Ionic Clay Resources

Enova Mining Strengthens Expertise for East Salinas

Enova Mining Ltd (ASX:ENV) has secured a significant boost to its East Salinas rare earth element project by appointing Alexandre Magno Rocha da Rocha, a leading figure in Brazil’s rare earth geology. Mr da Rocha, backed by a specialist team from Geological Consultores Associados Ltda, brings decades of experience, notably his pivotal role in defining Brazil’s first ionic adsorption clay (IAC) rare earth deposits such as the Pela Ema deposit that underpins the Serra Verde operations. This move signals Enova’s intent to deepen its technical capabilities as it advances East Salinas, a recent discovery with encouraging high-grade mineralisation results.

Mr da Rocha’s credentials include foundational contributions to Brazilian Rare Earths’ flagship "Rocha da Rocha" project (ASX:BRE), which currently holds a market cap of approximately $1.5 billion. His expertise has been instrumental in positioning Brazil as an emerging player in the global rare earth supply chain, a sector traditionally dominated by Asia. The Serra Verde Group, recently acquired by USA Rare Earths for US$2.8 billion, underscores the value and strategic importance of the deposits Mr da Rocha helped define.

High-Grade Drilling Validates East Salinas Potential

East Salinas has delivered notable drilling results, confirming thick saprolite mineralisation amenable to ionic adsorption leaching. Key intercepts include 17 metres at 5,000 ppm total rare earth oxides (TREO) with 19% neodymium-praseodymium (NdPr) from surface, and several other intercepts demonstrating consistent high-grade mineralisation near surface. These results align with previous announcements, reinforcing Enova’s discovery narrative and the project’s potential to become a significant rare earth source outside Asia.

To refine resource definition and support metallurgical studies, Enova plans further auger drilling aimed at delineating the saprolite’s extent and thickness. This auger program complements ongoing metallurgical test work, including heap and dump leach studies, essential for assessing extraction viability. The Geological team’s metallurgical expertise will be critical in developing geo-metallurgical models that underpin future resource and economic evaluations. This approach follows earlier promising assay results and metallurgical insights reported by Enova in the first quarter of 2026, reflecting a methodical progression towards resource maturation.

Brazilian Rare Earths Portfolio and Regional Expansion

Beyond East Salinas, Mr da Rocha and his team will assess additional prospects within Enova’s portfolio, including the Carai and Santo Antonio do Jacinto projects. These sites are considered prospective for ionic adsorption clay rare earth mineralisation, potentially expanding Enova’s footprint in Brazil’s growing critical minerals sector. The consultancy’s support also extends to permitting and land management, navigating Brazil’s National Mining Agency (ANM) regulatory framework, a crucial factor for advancing exploration and development activities.

This strategic appointment builds on Enova’s recent capital raise and drilling campaigns, including the ongoing deep diamond drilling at Charley Creek in Australia, aimed at unlocking hard rock rare earth potential beneath alluvial deposits. The company’s diversified portfolio and multi-jurisdictional approach position it to leverage growing global demand for rare earth elements critical to clean energy and technology applications.
