Si6 Metals has picked up 300 square kilometres of rare earths ground in north-east Minas Gerais — a project it has dubbed Pimenta — adding to the Brazilian joint venture it shares with local exploration outfit Foxfire Metals. The acreage carries thorium anomalies across 26km of untested strike within magnetite-biotite granites holding significant allanite, a mineral group associated globally with large, low-cost deposits carrying high magnet rare earths content. Thorium-potassium ratio mapping has flagged a zone where weathering may have concentrated mineralisation, and Si6 is designing a drill program to test those profiles once the remaining licence applications come through. Read the full article for how Pimenta stacks up against allanite-hosted deposits overseas, and for the first Caldera drill results released earlier in the week.
