Vancouver, British Columbia - February 28, 2023 (www.waternewswire.com, Mining / Metals / Green Energy Stock news) Defense Metals Corp. ("Defense Metals" or the "Company") (TSX-V:DEFN / OTCQB:DFMTF/ 35D: FSE) is pleased to report favourable comminution results on multiple samples extracted from the Wicheeda deposit. The data allows the design of the crushing and grinding plant that will be an integral part of the planned Wicheeda development. These data are essential inputs to the upcoming pre-feasibility study (PFS).
Comminution, i.e., crushing and grinding, will be the first step in the processing of material mined from the Wicheeda deposit. In the process, coarse, as-mined, rocks are reduced in size to sand-like particles, typically less than 1 mm in size, and suitable for upgrading by flotation or other means. Comminution usually accounts for a significant percentage of the energy demand, production cost and carbon footprint of a mineral processing plant.
John Goode, Metallurgy Advisor, stated: "Comminution tests on seventeen variability samples and a Master Composite show that the ore is soft, amenable to conventional grinding operations and has a low abrasion index. The recent results confirm, and expand on data obtained from a 30 t bulk sample taken in 2019. The data show that a conventional semi-autogenous grinding (SAG) mill-ball mill circuit will work well and that grinding energy and supply costs will be relatively low."
Seventeen variability samples and a Master Composite were made from drill core taken from the Wicheeda deposit. The variability samples covered different lithologies, depths, areas and grades of the deposit. The Master Composite had a mass of 260 kg and included all lithologies in the approximate ratios of their mass in the deposit.
SGS Lakefield performed all of the comminution tests. The SMC testing protocol is an industry-standard method of evaluating the amenability of material to grinding in a semi-autogenous grinding (SAG) mill. The Bond rod and ball mill indices and abrasion index are also industry-standard tests performed on crushed ore and are essential to the accurate sizing of a grinding circuit.
The comminution data will be used, along with other information, during the upcoming pre-feasibility study (PFS) to design the comminution circuit for the Wicheeda project.
PDAC Convention, Toronto, March 5 - 8, 2023
The Company is also pleased to announce that it will be attending this year's Prospector's and Developer's Annual Convention (PDAC) in Toronto, Ontario, Canada from Sunday, March 5 to Wednesday, March 8, 2023.

About the Wicheeda REE Property
Defense Metals 100% owned, 4,262-hectare (~10,532-acre) Wicheeda REE property is located approximately 80 km northeast of the city of Prince George, British Columbia; population 77,000. The Wicheeda REE Project is readily accessible by all-weather gravel roads and is near infrastructure, including hydro power transmission lines and gas pipelines. The nearby Canadian National Railway and major highways allow easy access to the port facilities at Prince Rupert, the closest major North American port to Asia.
The 2021 Wicheeda REE Project Preliminary Economic Assessment technical report ("PEA") outlined a robust after-tax net present value (NPV@8%) of $517 million and an 18% IRR. This PEA contemplated an open pit mining operation with a 1.75:1 (waste:mill feed) strip ratio providing a 1.8 Mtpa ("million tonnes per year") mill throughput producing an average of 25,423 tonnes REO annually over a 16 year mine life. 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.
