DEFENSE METALS CORP. INITIATES PRE-PILOT HYDROMETALLURGICAL OPTIMIZATION FOR ITS RARE EARTH ELEMENTS PROJECT
Defense Metals Corp. has commissioned SGS Canada Inc. to complete additional prepilot hydrometallurgical test work utilizing high-grade rare earth element (REE) mineral concentrate produced during the company's highly successful 26-tonne flotation pilot plant that yielded a mineral
concentrate averaging 7.4 per cent NdPr oxide (neodymium-praseodymium) (see Defense Metals news release dated Sept. 23, 2020).
Craig Taylor, chief executive officer, comments:
"The previously closed 25-cent-per-share private placement financing will be used to conduct additional fill-in hydrometallurgical test work with the objective of capitalizing on opportunities that have been identified to optimize and improve on our already exceptional hydromet recoveries. As previously disclosed, we intend to complete the preliminary economic assessment by the end of the Q1 2021."
Bench-scale hydrometallurgical test work finalized earlier this year and designed to inform operation of a large-scale hydrometallurgical pilot plant yielded approximately 90 per cent TREE
(total rare earth elements) recovery from concentrate
into a chloride-based leach solution and production of a high-grade 67.5 per cent TREE mixed hydroxide precipitate (see Defense Metals news release dated Feb. 20, 2020).
The recently commissioned fill-in test work will have the following objectives:
- Increase overall REE extraction into high-purity final REE precipitate;
- Examine impact of recycling certain process streams on metallurgical performance;
- Prepare for the operation of a hydrometallurgical pilot plant.
Wicheeda REE project
The Wicheeda REE project has indicated mineral resources of 4.89 million tonnes averaging 3.02 per cent LREO (light rare earth elements) and inferred mineral resources of 12.1 million tonnes averaging 2.9 per cent LREO.
The scientific and technical information contained in this news release as it relates to the Wicheeda REE property has been reviewed and approved by Kristopher J. Raffle, PGeo (British Columbia), principal and consultant of Apex Geoscience Ltd. of Edmonton, Alta., a director of Defense Metals and a qualified person as defined in National Instrument 43-101 -- Standards of Disclosure
for Mineral Projects.
