Cosmos Exploration (ASX: C1X) has reported new exploration results highlighting significant rare earth exploration potential associated with a large carbonatite complex at its 100%-owned Byro East Project, Western Australia.
The time spent at Byro East has identified widespread rare earths potential in carbonatitic rocks coincident with chemistry and geophysics which were not previously understood to be present.
Rock chip sample BY23K360 (1.1% TREYO, 21% NdPr) from the Leatherback prospect confirms the presence of a weathered carbonatite-alkaline intrusion, coincident with multi-kilometre long REE soil geochemistry, magnetic, and gravity high anomalies.
Ore grade concentrations of scandium with 263ppm Sc203 and 0.7% TREYO (30% NdPr) returned in rock chip sample LRBY21, interpreted to be an iron oxide-rich weathered ferrocarbonatite, pyroxenite-bearing carbonatite, or phoscorite.
Additionally, Leatherback’s coincident magnetic and gravity features with elevated REE-Ba-Sr-Nb-Ca-NiCr-Mg soil geochemistry further substantiate the presence of a mafic to ultramafic alkaline-carbonatite complex at the Leatherback prospect.
Cosmos has said that world-renowned expert Professor Ken Collerson has confirmed that the rock chip geochemical signatures are akin to alkaline and carbonatite complex magmatism, drawing parallels to the Kola Peninsula (Finland/Russia) and Mirima Hill carbonatite (Kenya).
Further on-ground field checks and rock chip sampling to investigate the source of the geochemical anomalies are to commence shortly, and soil sampling is scheduled to begin when crews become available in mid-September. The crew will look to in-fill previous 320m x 80m spaced surveys at the Dottyback-Leatherback prospects and regional 450m x 450m spaced geochemical patterns over priority anomalies.
