Defense Metals starts construction of Hydrometallurgical Pilot Plant with commissioning at SGS Lakefield scheduled for March 2023

VANCOUVER, BC, Feb. 21, 2023 /PRNewswire/ - Defense Metals Corp. ("Defense Metals" or the "Company") (TSXV: DEFN) (OTCQB: DFMTF) (FSE: 35D) is pleased to announce that construction of the hydrometallurgical pilot plant has started and commissioning is scheduled to start in the second half of March.

Craig Taylor, CEO of Defense Metals, stated:

"We are excited to enter this important milestone of building and running the hydrometallurgical pilot plant, which is scheduled to be commissioned in late March. Pilot operations will be done in two segments and should be completed by the end of April. A successful pilot plant program will be essential for the completion of the engineering design and economics of the planned pre-feasibility study."

Following the successful completion of laboratory flotation and acid bake tests from December 2021 to date, Defense Metals is now ready to build a hydrometallurgical pilot plant. It is important to note that the Independent Preliminary Economic Assessment1 was based on a different hydrometallurgy flowsheet, the gangue-leach – caustic-crack process (see the Company's March 31, 2022 news release). However, after numerous laboratory tests the Company decided to pursue piloting of the less complex acid bake process, which has, in initial test-work, yielded better recovery rates, is an industry standard, and has the potential for improved economics.

The objective of the pilot plant is to demonstrate at a larger scale, and with continuous operation, the processing of Wicheeda flotation concentrate to produce rare earths using the acid bake flowsheet, to help confirm the quality of the project, and to gather data required for the pre-feasibility study.

The pilot plant will be configured to produce a high-purity rare earth precipitate suitable as feed for a separation plant. Samples produced from the pilot plant will also be shared with potential end-users for product development and qualification.

Methodology

The plant is being built at SGS Lakefield, Ontario and will run in two segments for approximately two weeks. The feed for the plant will total approximately 600 kg of mineral concentrate that was generated from a flotation pilot plant operated on a bulk sample from the Wicheeda deposit.

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% IRR1. 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.
