Enova Mining Confirms High-Grade Rare Earth Mineralisation and Expands Brazilian Footprint

East Salinas Project Extends High-Grade Ionic Clay Rare Earth Mineralisation

Enova Mining (ASX:ENV) has reinforced the East Salinas Project in Brazil as a significant rare earth element (REE) target, with recent assay results confirming extensive ionic adsorption clay (IAC) mineralisation hosted in saprolite. The Naked Hill Prospect continues to deliver thick intercepts of total rare earth oxides (TREO) with notable neodymium-praseodymium (NdPr) ratios, including 13 metres at 2,418ppm TREO and 21% NdPr from surface, and peak grades reaching 4,874ppm TREO at 25% NdPr.

These results validate the continuity of REE mineralisation across multiple intrusive bodies within the Medina Intrusive Granite Complex, underpinning a district-scale saprolite-hosted system. The company’s integrated exploration approach, combining geophysical surveys, hyperspectral analysis, and targeted drilling, has successfully delineated high-grade zones suitable for further resource definition.

Meanwhile, the newly identified Curioso Prospect within the southern tenements of East Salinas has expanded the project’s footprint. Initial auger drilling at Curioso has confirmed multiple saprolite intercepts exceeding 1,000ppm TREO, with NdPr ratios up to 32%, highlighting a geological setting analogous to Naked Hill. Leach test recoveries from Curioso samples are pending, with further auger drilling underway to map the saprolite extent and thickness.

Metallurgical Advances Highlight Processing Potential

Metallurgical test work at East Salinas, conducted by SGS Geosol Laboratory, has shown promising leach recoveries for saprolite samples. Notably, a peak magnetic rare earth oxide (MREO) recovery of 84% was achieved from saprolite intervals at Naked Hill. These results support the viability of IAC leaching as a processing pathway, although further optimisation is planned to enhance recovery rates across the project.

At Curioso, metallurgical testing is ongoing, with leach test results expected to clarify extraction efficiencies and inform future processing designs. Enova is also advancing metallurgical studies at its CODA East and CODA Central projects in Brazil, focusing on titanium, niobium, scandium, and REE concentration through beneficiation and magnetic separation techniques.

Northern Territory Drilling Confirms Thick Saprolite-Hosted REE Zones

In Australia’s Northern Territory, the Charley Creek Project has delivered multiple high-grade REE intercepts from a seven-hole drilling program combining air-core and diamond coring. Highlights include 12 metres at 1,400ppm TREO with 22% NdPr and 25.6 metres at 1,583ppm TREO with 17.5% NdPr, confirming saprolite as the main host of mineralisation. Fresh gneissic basement rock beneath the saprolite showed no significant REE mineralisation within the current drilling area.

Drilling challenges such as lower-than-expected core recovery curtailed the program, but the results validate historical high-grade intercepts and support planned mineral characterisation and metallurgical test work to refine processing strategies. Additionally, Enova continues to investigate alluvial REE mineralisation at Charley Creek through wet heavy mineral concentration techniques, with bulk sampling and process improvement studies underway.

Santo Antônio do Jacinto Project Shows Early REE Enrichment

Initial scout auger drilling at the Santo Antônio do Jacinto Project in Brazil has confirmed near-surface REE enrichment within saprolite overlying a porphyritic granite complex. Assay intercepts include 6 metres at 2,176ppm TREO with 26% NdPr from surface, indicating a promising granite-derived saprolite-hosted REE system. Metallurgical leach test recoveries from 26 saprolite samples ranged from 1.4% to 15.1% TREO, with heavy rare earth oxide recoveries up to 45.3%, though variability suggests further optimisation is needed.

Enova plans additional auger drilling to test unassessed areas and refine exploration targets, alongside continued metallurgical evaluation as new samples become available.

Strategic Appointment of Brazilian REE Expert Enhances Project Development

To bolster its Brazilian exploration efforts, Enova has appointed Alexandre Magno Rocha da Rocha, a renowned REE geologist credited with early discoveries of Brazil’s ionic adsorption clay deposits, including the Serra Verde operation. Supported by Geological Consultores Associados Ltda, Mr da Rocha brings over 30 years of academic and industry experience, including consultancy roles with major mining companies. His expertise will focus on mineralogical characterisation, metallurgical testing, and field support across Enova’s East Salinas, Caraí, and Santo Antônio do Jacinto projects.

This appointment aligns with Enova’s strategy to leverage local expertise and accelerate the advancement of its critical minerals portfolio within Brazil’s stable mining jurisdiction.

Financial Position and Next Steps

Enova reported a net operating cash outflow of A$796,000 for the quarter ending 30 June 2026, with cash reserves at A$630,000. The company has previously raised A$2 million earlier in 2026 to support exploration activities. Planned next steps include follow-up auger drilling at East Salinas and Santo Antônio do Jacinto to delineate saprolite mineralisation, ongoing metallurgical testing to optimise leach recoveries, and further resource definition drilling to advance project development.
