Highlights

  • OD6 Metals’ share price rose 48% to AUD 0.052 on 13 August 2025 following the announcement of high-quality MREC and MREH production results.

  • Metallurgical testing conducted by ANSTO produced ~56% TREO MREC and ~59% TREO MREH from heap leach liquor at the Splinter Rock Rare Earth Project.

  • The company is engaging with potential offtake partners in North America, Europe, and Asia while advancing an Optioneering Study with ANSTO and CPC Engineering.

On 13 August 2025, OD6 Metals Limited (ASX:OD6) saw its share price increase by 48% to trade at AUD 0.052 per share. The rise followed the company’s announcement of the successful production of Mixed Rare Earth Carbonate (MREC) and Mixed Rare Earth Hydroxide (MREH) products from metallurgical testing undertaken by the Australian Nuclear Science and Technology Organisation (ANSTO).

Metallurgical Results

The products were produced from heap leach liquor following nine months of testing and refining the processing flowsheet for the Splinter Rock Rare Earth Project. The work resulted in enhanced processing efficiency and improved rare earth product quality.

The testing yielded MREC with approximately 56% Total Rare Earth Oxides (TREO) using a simplified and scalable heap leach and impurity removal process flowsheet. MREH with approximately 59% TREO was also produced using the same process but incorporating Sodium Hydroxide (NaOH) to precipitate the saleable product.

Product Characteristics

According to the company, over 90% of the product value is expected to come from Magnetic Rare Earth content, including neodymium (Nd), praseodymium (Pr), dysprosium (Dy), and terbium (Tb). The products demonstrated low levels of impurities such as aluminium (Al), iron (Fe), phosphorus (P), and silicon (Si), with uranium and thorium content measuring below 0.001% combined.

The results indicated no expected refinery penalties, which the company stated should allow for optimal commercial payability. OD6 noted that the quality of its MREC and MREH meets or exceeds global benchmarks, potentially positioning the company for favourable terms in future offtake agreements.

Development and Commercial Engagement

OD6 is working with ANSTO and CPC Engineering on an Optioneering Study to determine the optimal development pathway for the Splinter Rock Rare Earth Project. The company is also in discussions with potential offtake partners to evaluate commercial payability options.

In parallel, OD6 is expanding its network of potential downstream customers in key markets, including North America, Europe, and Asia. The company noted that its future products are suitable for high-technology applications in sectors such as defence, electronics, and renewable energy, due to their magnetic and electronic properties.
