NEOTECH METALS CORP. REPORTS POSITIVE METALLURGICAL RESULTS DEMONSTRATING HIGH LEACHABILITY OF RARE EARTHS AT ITS HECLA-KILMER PROJECT IN ONTARIO, CANADA
Neotech Metals Corp. has released positive test results from the continuing metallurgical studies for the Hecla-Kilmer project from SGS-Lakefield Canada Inc. Results from 11 batch flotation tests -- designed to assess recovery rates, concentrate grades and leachability under varying conditions -- yielded highly encouraging outcomes. In a six-hour digestion at just 50 C, the test successfully deported between 97 per cent and 99 per cent of REEs (rare earth elements) into solution, demonstrating the amenability of the mineralization to low-temperature acid leaching.
In addition to the positive leach test, additional metallurgical results include:
- 75.0-per-cent total rare earth oxide (TREO) recovery, including consistent recovery of praseodymium, neodymium and other magnet rare earths (PMREO), as outlined in Table 1 -- highlighting the potential for efficient downstream processing;
- 78.0% niobium (Nb2O5) recovery through gravity separation, confirming amenability to low-cost, conventional beneficiation;
- 89.1-per-cent phosphate (P2O5) recovery, with 100 per cent of phosphate reporting to solution during leaching, indicating potential for a secondary phosphate byproduct stream;
- Successful leach test completed using just 36 per cent hydrochloric acid, validating the amenability of the mineralization to conventional acid leach techniques under relatively moderate conditions.
These initial results represent the first-ever metallurgical campaign conducted at Hecla-Kilmer. It is important to note that the data are based on a single leach test. While the outcomes are highly encouraging, further metallurgical work is planned to optimize processing conditions and account for variability in lithology and geochemistry across the broader mineralized system. The next phase of test work will include additional flotation testing, optimization and enhancement to complement the leach testing, with the goal of improving overall recovery and process efficiency. This next phase of metallurgical studies will focus on validating scalability, refining flow sheet design and ensuring consistency across representative sample types.
"In the context of North American rare earth projects, this is a significant milestone for Neotech," said Reagan Glazier, chief executive officer. "These results confirm that the apatite-hosted mineralization at Hecla-Kilmer is not only high grade but also uniquely leachable -- with over 75-per-cent total rare earth oxide recovery and up to 99 per cent of the rare earths brought into solution under mild conditions. That kind of metallurgical simplicity is exceptionally rare in this sector and represents a significant derisking event for the project. As governments and industry work to secure critical mineral supply chains, positioning Hecla-Kilmer as a leading candidate for near-term development in North America."
Methodology and quality assurance
A master composite, weighing approximately 200 kilograms, was prepared from the assay pulps of hole HK22-013 by SGS. It was homogenized, stage crushed to minus 10 mesh and split into test charges.
Head grade, batch and concentrate products were determined through lithium-borate fusion of a 0.5-gram sample analyzed through wavelength dispersion X-ray fluorescence (WD-XRF). The remaining rare earth elements for the head sample were determined through 0.5-gram sodium-peroxide fusion multielement ICP-MS.
The SGS analysis included a quality assurance/quality control (QA/QC) program, including the insertion of rare earth element standards and blank samples. Neotech detected no significant QA/QC issues during review of the data. Neotech is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data referred to herein. SGS Minerals Lakefield is ISO/IEC 17025 and ISO 9001:2015 accredited. SGS is independent of Neotech.
