Defense Metals Flotation Results Yields High Grade Mineral Concentrate at Various Grades and Lithologies

Defense Metals Corp. (“Defense Metals” or the “Company”; TSX-V:DEFN / OTCQB:DFMTF / FSE:35D) announces the initial flotation results from variability samples.

Craig Taylor, CEO, and Director of Defense Metals stated: “Flotation results from the on-going program of testwork at SGS Lakefield confirm the basis of the Preliminary Economic Assessment (PEA)[1] and show that the Wicheeda deposit can produce a high-grade rare earths mineral concentrate at high recovery rates with conventional flotation from a range of lithologies and grades. These are some of the best flotation results among rare earths development projects. We are encouraged with the exploration and metallurgy results to date, and confident that the pre-feasibility study, which we anticipate will commence shortly, will show that Wicheeda is well positioned to become one of the next rare earths producers in North America.”

The Company is currently performing flotation tests on samples of different lithologies. The Wicheeda deposit is characterized by three main rare earths bearing lithologies, dolomite carbonatite (DC) which is the dominant lithology, xenolithic carbonatite (XE), and syenite (SYN).  Limestone is the major waste rock lithology. The predominant rare earths minerals are, synchysite/parisite, bastnäsite, and monazite.

• The results to date indicate that high grade mineral concentrate containing more than 40% total rare earths oxides (TREO) at a recovery rate exceeding 80% has been produced from all fully tested DC samples and a Master Composite (MC) containing all lithologies, from material with a head grade of >2% TREO.
• The XE material, representing about 24% of the deposit and encountered late in the mine life, can deliver a 38% TREO concentrate at ~70% recovery rate at feed grades ~1.4%TREO.
• SYN material, which represents about 3% of the deposit and is only encountered late in the mine life, has the lowest grade but shows ~14x upgrade ratio (from 1.1% to 14.6%TREO) at recovery rates ~79%.
• Approximately 70 flotation tests have been performed. Several assay results are pending, and additional tests are continuing on variability samples of DC, XE, SYN, and mixed samples.

Table 1. Selected Wicheeda Flotation Results

Table 1, shows selected flotation results on samples from different lithologies. The Composite samples contain a mixture of intervals from different drill cores taken from different areas of the deposit and different depths and represent the different lithologies.  The master composite sample (MC in Table 1) includes the three lithologies (DC (73.4%), XE (22.5%), SYN (3.8%)).  The variability samples in Table 1 are just two of the seventeen such samples being tested.

The DC lithology accounts for more than 70% of PEA mill feed (Figure 1), and in the first 8 years of the expected mine life, over 90% of the flotation plant feed will be DC material, with higher rare earths grade, with the later years being mostly DC and XE material at relatively lower grades.

Methods

Samples were obtained from drill cores and separated into different lithologies. They were crushed and ground to 80% passing ~80µm and subjected to flotation tests. Several flotation parameters were investigated, including the collector types and dosage, depressant types and dosage, the addition of activator, pulp temperature, pulp density, pulp pH, and flotation feed size. All tests were performed at SGS Minerals Lakefield, Ontario.

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 laboratory. SGS is independent of Defense Metals Corp.

About the Wicheeda Rare Earth Property

The 100% owned 4,244-hectare Wicheeda Rare Earths Property, located approximately 80 km northeast of the city of Prince George, British Columbia, is readily accessible by all-weather gravel roads and is near infrastructure, including power transmission lines, the CN railway, and major highways.

The Wicheeda Rare Earths Project yielded a robust 2021 preliminary economic assessment technical report (PEA) that demonstrated an after-tax net present value (NPV@8%) of $517 million, and 18% IRR[2]. A unique advantage of the Wicheeda Rare Earths Project is the production of a saleable high-grade flotation concentrate. The PEA contemplates a 1.8 Mtpa (million tonnes per year) mill feed from an open pit mining operation with 1.75:1 (waste:mill feed) strip ratio over a 19 year mine (project) life producing an average of 25,423 tonnes REO annually. A Phase 1 initial pit strip ratio of 0.63:1 (waste:mill feed) would yield rapid access to higher grade surface mineralization in year 1 and payback of $440 million initial capital within 5 years.
