Medallion Resources Ltd (TSX-V: MDL; OTCPK: MLLOF) has been working for a number of years on a smart approach to achieve significant and low-cost production of rare-earth magnet metals. Our plan focusses on processing monazite, a readily available by-product mineral. Monazite is a phosphate mineral containing 60% rare earths and is the world`s original commercial rare-earth source. Monazite remains available as a by-product from North American, Australian and African heavy mineral-sands operators. Medallion believes that this is the best new non-Chinese source of NdPr and other rare earths. Given the long timeframes and high-capital investment required to develop new mining operations, Medallion offers lower risk and a viable alternative to deliver near-term magnet metals.
