OD6 Metals Limited (ASX: $OD6) has announced positive results from metallurgical testing conducted by the Australian Nuclear Science Organisation (ANSTO). The testing revealed that the removal of coarse material (greater than 75um) improved Total Rare Earth Oxide (TREO) grades by up to 224% (157% average) and led to a reduction in hydrochloric acid (HCI) consumption by up to 79% (35% average reduction) to approximately 10kg HCI/t total screened ore. These results indicate the potential for improved project economics and rare earth recovery for the company's Splinter Rock Project.
Brett Hazelden, Managing Director of OD6 Metals, highlighted the significant increase in TREO grades achieved by removing coarse material greater than 75um. He emphasized the corresponding benefit of consuming an average of 35% less acid as a total of product processed, which could positively impact the overall cost profile of any future operation. Additionally, Darren Holden, Non-Executive Chair, emphasized the importance of applying science and engineering to the development of clay Rare Earth Elements (REE) in Australia, indicating the potential for future economic studies and the prioritization of the best zones within the company's thick clay basins.
The metallurgical testing results demonstrate the potential for significant improvements in TREO grades and acid consumption, indicating a positive outlook for OD6 Metals' Splinter Rock Project. The company's simplified processing map, utilizing a chlor-alkali facility, presents a cost-effective and environmentally friendly approach to leaching rare earth elements. The forward works program, including mineral resource estimation, bench scale tests, impurity removal trials, and process modeling, reflects OD6 Metals' commitment to further optimizing its operations. With the increasing importance of REEs in the global economy, OD6 Metals' exploration and development efforts position the company to contribute to the growing demand for these critical minerals.
