VANCOUVER, BC, Aug. 4, 2020 /CNW/ - 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.
