Neotech Metals Reports Breakthrough Rare Earth Recovery at Hecla-Kilmer, Eyes Near-Term Development Amid New Financing Push

Highlights

• Metallurgical tests by SGS-Lakefield show 97-99% leachability of rare earth elements using low-temperature hydrochloric acid
• Project demonstrates high recovery rates:
  • 75% Total Rare Earth Oxide (TREO)
  • 78% Niobium
  • 89.1% Phosphate
• Promising results position Hecla-Kilmer as a strong candidate for near-term development in North America's critical mineral supply chain

​Canada-based Neotech Metals Corp. has announced (opens in a new tab) promising metallurgical test results from its Hecla-Kilmer project in Ontario, Canada.

Conducted by SGS-Lakefield Canada Inc., the tests revealed that a 6-hour digestion at 50°C using 36% hydrochloric acid achieved a 97–99% leachability rate for rare earth elements (REEs). Additional findings include a 75% recovery rate of Total Rare Earth Oxides (TREO), 78% recovery of Niobium (Nb₂O₅) through gravity separation, and 89.1% recovery of Phosphate (P₂O₅), with all phosphate reporting to solution during leaching. ​

These results suggest that the apatite-hosted mineralization at Hecla-Kilmer is highly amenable to conventional, low-temperature acid leaching, potentially simplifying processing and reducing costs. This development positions the project as a strong candidate for near-term development, contributing to North America's critical mineral supply chain. However, these conclusions are based on initial tests; further metallurgical studies are planned to optimize processing conditions and validate scalability. ​
