Enova Mining Discovers High-Grade Rare Earth Mineralisation at Curioso Prospect

Curioso Prospect Emerges as High-Grade REE Target

Enova Mining Limited (ASX:ENV) has extended its rare earth element (REE) exploration footprint at the East Salinas Project in Brazil with the discovery of the Curioso Prospect. Initial auger drilling across ten holes has confirmed saprolite-hosted REE mineralisation starting from surface, with assays from six holes revealing multiple intercepts boasting Total Rare Earth Oxide (TREO) grades exceeding 1,000 ppm and attractive neodymium-praseodymium (NdPr) ratios.

Key intercepts include 8 metres at 1,590 ppm TREO with 20% NdPr and a standout peak of 2,218 ppm TREO at 16% NdPr from 8 to 9 metres depth. These results align with the company's geological model, which associates mineralisation with the Medina Intrusive Granite Complex, hinting at a district-scale saprolite-hosted REE system.

Geological Setting and Mineralisation Characteristics

The Curioso Prospect lies within the southern tenements of East Salinas, an area dominated by granitic and granodioritic intrusives overlain by a weathered saprolite layer. The saprolite hosts the REE mineralisation, consistent with intrusive-derived systems. Geological logging and surface geochemical sampling confirm the continuity of mineralised saprolite over multiple intrusive bodies, supporting the prospect's potential scale.

Samples were collected using lightweight auger drilling rigs targeting near-surface saprolite horizons. The saprolite is characterised by soft, clay-rich, reddish-brown material with preserved granitic textures, ideal for hosting ionic adsorption clay (IAC) style REE mineralisation. Leach testing is underway to assess recovery potential, a critical step given the importance of cost-effective extraction in REE projects.

Strategic Implications for Enova Mining's REE Portfolio

Curioso adds a new dimension to Enova's East Salinas Project, complementing previous discoveries such as the Naked Hill Prospect. CEO Eric Vesel highlighted the shallow, surface-level mineralisation as a potential advantage for development economics, especially given the high grades and NdPr proportions that are in line with market demand for magnet rare earths crucial to energy transition technologies.

Enova's exploration strategy integrates geophysical data, hyperspectral analysis, and systematic drilling to delineate the extent and continuity of mineralisation. The company's Brazilian geology team continues to play a pivotal role in advancing exploration efficiently within this stable, investor-friendly mining jurisdiction.

Next Steps and Exploration Outlook

With assay results pending from four additional auger holes and leach test recoveries, Enova is pressing ahead with further auger drilling to define the lateral and vertical extent of saprolite mineralisation at Curioso. These efforts will feed into planning for resource delineation drilling and metallurgical test work aimed at confirming the project's economic viability.

East Salinas remains a cornerstone of Enova's critical minerals ambitions, situated in Minas Gerais, Brazil; a region known for its robust mining infrastructure and supportive regulatory environment. The ongoing exploration at Curioso and other projects within the company's portfolio will be key to unlocking value amid growing global demand for rare earth elements.
