Enova Mining (ASX:ENV) said surface sampling across the East Salinas Medina granitic complex in Brazil confirmed multiple high-grade rare earth element exploration targets, according to a Wednesday Australian bourse filing.

Rock-chip assays returned highly anomalous total rare earth oxide with grades of up to 1.87%, with elevated levels of neodymium-praseodymium oxide, terbium, dysprosium, and ytterbium.

The firm will focus on refining targets through detailed mapping, geochemical analysis, and geophysical surveys to define mineralized zones and prioritize drill-ready targets. It is also conducting a mineralogical and beneficiation study at CIT Senai.
