Important Improvement To Defense Metals Process Flowsheet

In This Article:

VANCOUVER, BC, Jan. 14, 2025 /CNW/ - Defense Metals Corp. ("Defense Metals" or the "Company"); (TSXV: DEFN) (OTCQB: DFMTF) (FSE:35D) is pleased to advise that it has added to the flowsheet of its hydrometallurgical plant a solvent extraction ("SX") circuit in order to remove low-value Cerium ("Ce") and Lanthanum ("La"). This additional circuit would increase the Neodymium and Praseodymium ("NdPr") oxide assay of the mixed rare earth carbonate ("MREC") from 14% on a total rare earth oxide ("TREO") basis to at least 85%.

As a result, the "basket value" of the enhanced MREC would increase significantly and would be among the highest of any existing or planned light rare earth production outside of China. This has been confirmed by Argus Media which has compared the value of this product basket to that of all the companies for which they have data.

In addition, the enhanced MREC significantly reduces the required capacity of the product handling equipment, the mass of the MREC to be transported, and the mass of separation plant feed per unit of NdPr oxide.  The elimination of La and Ce from the MREC makes the product far more attractive to downstream processors than the product which was initially envisaged to be produced. While this change to the flowsheet will somewhat increase the capital cost of the project it is believed that the benefits of this change will far outweigh its costs.

Mr. John Goode, P.Eng., Defense Metals Consulting Metallurgist said:

"The SX plant has been designed conservatively using industry standard and proven methods supplemented by bench scale tests. Hundreds of SX circuits similar to that proposed are successfully in operation around the world."

Mr. Mark Tory, President and CEO added:

"I am impressed with the quality of the metallurgical work which has been done by the company under the leadership of John Goode who is recognised worldwide as one of the leading experts in this type of work."

The pre-feasibility study that, as already announced, is expected to be released by Defense Metals in Q1, will include the SX circuit as part of the overall project design.
