Defense Metals Flotation Pilot Plant Achieves Initial Positive Results

04.08.2020  |  CNW
VANCOUVER, Aug. 4, 2020 - Defense Metals Corp. ("Defense Metals") (TSX-V: DEFN) (OTCQB: DFMTF) (FSE: 35D) is pleased to provide an update with respect to ongoing flotation pilot plant processing of its 30 tonne Wicheeda Rare Earth Element (REE) Property ("Wicheeda") bulk sample underway at the SGS Canada Inc. ("SGS") Lakefield, ON metallurgical test facility.

To date a total of 14 pilot plant processing runs have been completed since initiation of pilot plant testwork on June 11, 2020. Mass balance results for completed pilot plant runs are presented below (Table 1). Highlights of the recently completed bulk sample flotation pilot plant are:

  • 16 tonnes bulk sample feed processed over 118 hours of operation to date
  • Approximately 750 kg of flotation concentrate produced (dry weight at ~15% moisture content)
  • Process run concentrate grades ranging from 45.4% up to 56.7% (averaging 51.6%) LREO (light rare earth oxide expressed as the sum of light rare earth elements expressed as oxides Ce2O3+La2O3+Nd2O3+Pr2O3)
  • Process recovery ranging from 53.8% up to 79.1% (averaging 70.2%) LREO
  • Low average 6.2% mass yield to concentrate

Scaled-up flotation pilot plant results to date compare very favourably, and with respect to concentrated grade exceed, benchmark locked-cycle flotation tests that produced a high grade 48.7% LREO flotation concentrate at 85.7% LREO recovery (See Defense Metals News Release dated October 23, 2019). The results demonstrate progressive LREO recovery improvement with successive tests conducted under varying process conditions designed to improve the circuit stability and metallurgical performance.

A long 30 hour continuous operation test run (PP-15) was completed last week based on PP-14, and mass balance results are currently pending. SGS has informed Defense Metals that the balance of the bulk sample material will be processed this week during a final 30 hour continuous operation run designed to test circuit stability at lower temperature.

Craig Taylor, CEO of Defense Metals, stated; "We are exceedingly pleased with these initial flotation pilot plant test results. The Wicheeda REE Deposit mineralization continues to deliver exceptional metallurgical performance. We have shown that in a pilot plant setting we are able to exceed concentrate grades achieved during bench-scale flowsheet development. Defense Metals believes the results released today demonstrate the viability of large-scale bulk sample flotation processing of Wicheeda REE Deposit material. We look forward to completion of the balance of flotation pilot plant testwork this week. We expect to release the final results and a summary of all the testwork in the coming months."

About the Wicheeda REE Property

The 1,708 hectare Wicheeda REE Property, located approximately 80 km northeast of the city of Prince George, British Columbia, is readily accessible by all-weather gravel roads and is nearby to infrastructure, including power transmission lines, the CN railway and major highways.

Geologically, the property is situated in the Foreland Belt and within the Rocky Mountain Trench, a major continental geologic feature. The Foreland Belt contains part of a large alkaline igneous province, stretching from the Canadian Cordillera to the southwestern United States, which includes several carbonatite and alkaline intrusive complexes hosting the Aley (niobium), Rock Canyon (REE), and Wicheeda (REE) deposits.

Qualified Person

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, P.Geo. (BC) Principal and Consultant of APEX Geoscience Ltd. of Edmonton, AB, a director of Defense Metals and a "Qualified Person" as defined in National Instrument 43-101 – Standards of Disclosure for Mineral Projects. Mr. Raffle verified the data disclosed which includes a review of the analytical and test data underlying the information and opinions contained therein.

Methodology and QA/QC

The Wicheeda flotation test charges were prepared by SGS from the 30 tonne Wicheeda sample which was crushed to nominal 12.7 mm (1/2") using a combination of jaw and cone crushers. The crushed material was homogenized using a front-end loader over a period of several hours.

Head grade, and concentrate products for cerium, lanthanum, neodymium and praseodymium oxides were determined via lithium-borate fusion of a 0.5 gram sample analyzed via wavelength dispersion X-ray fluorescence (WD-XRF).

The SGS analysis included a quality assurance / quality control (QA/QC) program including the insertion of rare earth element standard and blank samples. Defense Metals detected no significant QA/QC issues during review of the data. Defense Metals is not aware of any sampling, recovery or other factors that could materially affect the accuracy or reliability of the data referred to herein. SGS Minerals Lakefield is an ISO/IEC 17025 and ISO9001:2015 accredited. SGS is independent of Defense Metals Corp.
