en.Wedoany.com Reported - Dimension News, Australian-listed exploration company Enova Mining Limited (ASX: ENV) confirmed in February 2026 the discovery of ion-adsorption rare earth mineralization at its East Salinas Project in Minas Gerais, Brazil. The deposit occurs within thick surface saprolite covering the Medina Intrusive Granitic Complex, with drilling results confirming continuity and thickness of mineralization over a strike length of approximately 4 kilometers. The company has completed over 65% of the first phase diamond drilling program and continues to advance exploration activities.
Enova Mining is an Australian Securities Exchange-listed exploration company focused on rare earth elements and battery metals, with a strategic portfolio of assets in Brazil (Minas Gerais and São Paulo states) and the Northern Territory of Australia. The East Salinas Project is located in northern Minas Gerais, covering approximately 22,706 hectares within the Medina Intrusive Granitic Complex, adjacent to Brazil's Lithium Valley, and offers year-round low-cost field operating conditions.
According to the company's disclosure, the first phase diamond drilling program of 14 holes has completed 989.63 meters of drilling, targeting multiple areas including Bald Hill, Naked Hill, Hairy Hill, and Flat Hill. Assay results from the first four holes revealed multiple high-grade intercepts: 2,741 ppm total rare earth oxides (TREO) with a neodymium-praseodymium (NdPr) ratio of 23% starting from 12 meters below surface; 3,467 ppm TREO with 21.5% NdPr at 7 meters; and a peak grade of 5,058 ppm TREO with 25% NdPr. Company CEO Eric Vesel stated that the drilling results confirm the strongest rare earth enrichment occurs within saprolite clays, with mineralization intersected in all drilled holes.
Ion-adsorption rare earth deposits are one of the world's primary sources of medium and heavy rare earths, characterized by rare earth elements adsorbed as ions onto clay mineral surfaces, which can be extracted through low-cost in-situ leaching processes. Preliminary leach test results indicate that the surface clays are amenable to low-intensity processing, offering potential for low-cost development. Enova Mining recently completed a A$2 million equity placement to advance drilling, sampling, and metallurgical test work at the East Salinas Project.
The discovery of the East Salinas rare earth deposit further enriches Enova Mining's critical minerals portfolio in Brazil. The company plans to use auger drilling to delineate the saprolite coverage and continue advancing resource estimation work.
