Enova Mining (ASX:ENV) has identified REE ionic adsorption-style enrichment with recent diamond drilling at the East Salinas project. Assay results from the initial four diamond holes of a 14-hole program returned multiple intercepts of total rare earth oxides (TREO), neodymium (Nd), and praseodymium (Pr) within saprolite.

CEO, Eric Vesel, said the results from Enova’s Brazilian base have identified continuity of REE mineralisation at depth and support the project’s association with magnetic REE potential identified in previous geochemical surveys.
“The East Salinas drilling program was designed as an initial test of rare earth mineralisation identified in surface sampling, and the results have materially improved our understanding of the system,” Mr Vesel said.
“Drilling has confirmed that the strongest REE enrichment occurs within surface saprolite clays, with mineralisation present across all holes drilled to date.
“The consistency and thickness of the saprolite intersected across targets spaced over approximately four kilometres suggests the potential for broad-scale saprolite coverage.”
The Australian company has also confirmed that initial ion adsorption clay (IAC) leach test results indicate that the surface clays are amenable to low intensity processing, a positive sign for a lower cost development.
“These results allow the company to progress the targeted auger drilling to define the extent of saprolite mineralisation and further assess metallurgical performance. The identification of ion adsorption style mineralisation at surface provides Enova with a clear and systematic pathway for advancing the East Salinas project,” Mr Vesel explained to Enova’s shareholders today.
Enova is preparing to undertake a deep diamond program at Charlie Creek, where it will follow up on ~1% TREO grade mineralisation that remained open at depth after air-core drilling was unable to reach fresh bedrock.
ENV has been steady at 0.7cps today.
