Defense Metals Receives Hydrometallurgical Pilot Plant Proposal From SGS Canada Inc.

VANCOUVER, BC, April 20, 2021 /CNW/ - Defense Metals Corp. ("Defense Metals") (TSXV: DEFN) (OTCQB: DFMTF) (FSE: 35D) is pleased to announce that it has received the formal Wicheeda Rare Earth Element ("REE") Project continuous hydrometallurgical pilot plant proposal from SGS Canada Inc. ("SGS").

Defense Metals is currently advancing the road accessible Wicheeda Critical Rare Earth Element (REE) Property, which is located close to infrastructure approximately 80 kilometres northeast of Prince George, British Columbia (BC). The Wicheeda project has indicated mineral resources of 4,890,000 tonnes averaging 3.02% LREO (Light Rare Earth Elements) and inferred mineral resources of 12,100,000 tonnes averaging 2.90% LREO¹.

The Company's highly successful 26-tonne flotation pilot plant campaign, also completed at the SGS Lakefield, ON metallurgical test facility, yielded approximately 1,200 kilograms of high grade REE mineral concentrate. Initiation of the hydrometallurgical pilot plant test program is the next step in establishing overall flowsheet operability at scale.

The test program will utilize representative flotation concentrate generated during the flotation pilot plant campaign and is expected to be completed in stages comprising initial gangue leach; caustic crack; primary acid leach; caustic re-crack; impurity removal; and REE precipitation. Parallel investigations into operability of acid and caustic regeneration; operability of gangue leach and caustic crack and primary acid leach circuits using recycled reagents; in addition to tailings neutralization studies will also be completed.

Once initiated, subject to the Company securing sufficient financing, completion of the various staged pilot campaigns is expected to take approximately 6 months. Key objectives of the planned hydrometallurgical pilot plant will be:

• To provide proof of operability of the proposed hydrometallurgical flowsheet for treatment of flotation concentrate under representative processing conditions including recycled process streams;
• To produce sufficient purified mixed rare earth hydroxide sample for downstream REE separation testing (leading to the production of a saleable NdPr oxide product);
• To confirm final product purity;
• To generate representative samples for solid-liquid separation testing, for use in the development of engineering cost estimates for key equipment.

As previously announced SGS (see Defense Metals News Release dated March 1, 2021) SGS is nearing completion pre-pilot infill hydrometallurgical testwork, initiated during late 2020, designed to assist in the finalization of the pilot plant flowsheet. The Company expects SGS to complete the remainder of pre-pilot testwork within 4-6 weeks time.

Craig Taylor, CEO of Defense Metals, stated: "Since initiating its option to acquire 100% of the Wicheeda REE Project in late 2018 and subsequently collecting a 26-tonne bulk sample, Defense Metals has rapidly advanced Wicheeda from an attractive prospect to compelling resource-stage project. Flotation and hydrometallurgical flowsheet development was completed in parallel with our highly successful 2019 diamond drill campaign that led to an upgraded and expanded mineral resource estimate. We are now excited to take the next step in demonstrating scale-up operability of the Wicheeda REE beneficiation process, leading to the production of a saleable NdPr oxide product."

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.
