This approach involves initially separating optimised Rare Earth regolith-clay fractions to improve leaching efficiency. It sets a strong foundation for subsequent processing stages whilst further reducing impurities like aluminium and iron and substantially reducing reagent consumption.\u201d<\/p>\n<p>Clark adds that the increase in REE head grade to 1,527ppm TREO \u2013 a substantial enhancement in the concentration of valuable REEs with exceptional percentages of dysprosium and terbium \u2013 made North Stanmore a significant player in the magnet REE sector.<\/p>\n<p>\u00a0<\/p>\n<h2><strong>Further activity<\/strong><\/h2>\n<p>VTM expects that successful beneficiation of the feed ore will further reduce reagent costs for the production of a MREC product and potentially improve the TREO concentration.<\/p>\n<p>The company is also looking into the opportunity to recover copper, cobalt and nickel in the solution as valuable by-products in the next round of metallurgical testing.<\/p>\n<p>Production of this further MREC test product is expected in April 2024.<\/p>\n<p>Further metallurgical leach tests on the &lt;53\u00b5m beneficiated material will also be carried out.<\/p>\n<p>Separately, VTM expects to upgrade the resource in early May 2024 following a successful infill drilling program totalling 13,718m in November 2023 that demonstrated significant sections and grades.<\/p>\n<p>\u00a0<\/p>\n\n<p><span class=\"mce_SELRES_start\">\ufeff<\/span><span class=\"mce_SELRES_start\">\ufeff<\/span>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p><em>This article was developed in collaboration with Victory Metals, 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.
