and<br \/>\n10m @ 65% neodymium, 61% praseodymium, 43% dysprosium and 50% terbium.<\/p>\n<p>Magnet rare earths (magREE) are used in the manufacture of permanent magnets found in electric vehicle motors and wind turbines and everyday consumer electronics.<\/p>\n<p>There\u2019s about 750g of magREE in every EV motor, which adds up quickly if the world is to see ~40m EVs sold each year by 2030, as per BloombergNEF estimates.<\/p>\n<p>Offshore wind turbines, on the other hand, require about 6t of magnets or 2t of rare earth metals.<\/p>\n<p>These high recoveries were achieved by standard leaching of low-cost ammonium sulphate (NH4)2SO4 and low leach times of 30-minute durations.<\/p>\n<p>\u00a0<\/p>\n<h2><strong>Potential to become largest ionic clay deposit outside China <\/strong><\/h2>\n<p>BCM described the recoveries received to date as \u201cexceptional\u201d and suggested a significant proportion of the REEs are present as ionically adsorbed clays, confirming Ema mineralisation which stretches for &gt;80km2.<\/p>\n<p>The recoveries also highlight the potential for the project to become one of the largest ionic clay-hosted deposits defined outside of China.<\/p>\n<p>\u00a0<\/p>\n<h2><strong>Focus shifts to maiden resource <\/strong><\/h2>\n<p>\u201cThe company is becoming increasingly confident that the &gt;80km2 of already defined rare earth mineralisation has the potential to be further expanded and developed into one of the largest ionic rare earth projects outside of China,\u201d BCM non-executive chairman Jeremy Robinson says.<\/p>\n<p>\u201cThese results provide further confirmation that the extensive Ema rare earth mineralisation is ionically absorbed clays that can result in high recoveries using low-cost ammonium sulphate.<\/p>\n<p>\u201cOur immediate focus is to complete the maiden Ema resource estimate with all the data having been handed over to the consultants for processing.<\/p>\n<p>\u201cWe are also proceeding with further metallurgical optimisation test-work at ANSTO which will commence shortly, with samples having already been delivered.\u201d<\/p>\n<p>\u00a0<\/p>\n<h2><strong>What\u2019s next? <\/strong><\/h2>\n<p>Metallurgical samples have now been delivered to ANSTO for additional optimisation work with the primary aim being to improve upon the recoveries obtained to date and determine opportunities for grade enhancement.<\/p>\n<p>\u00a0<\/p>\n\n<p><span class=\"mce_SELRES_start\">\ufeff<\/span>\u00a0<\/p>\n<p><em>This article was developed in collaboration with Brazilian Critical Minerals, a Stockhead advertiser at the time of publishing. <\/em><\/p>\n<p><em>\u00a0<\/em><\/p>\n<p><em>This article does not constitute financial product advice.
