News Release – Vancouver, British Columbia – September 29, 2021:Defense Metals Corp. (“Defense Metals”) (TSX-V:DEFN / OTCQB:DFMTF / FSE:35D) is pleased to provide a progress update with respect to its ongoing Wicheeda Rare Earth Element (REE) Project economic scenario analysis being conducted by SRK Consulting (Canada) Inc. (“SRK”).

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% LREO[1].

As previously reported (see Defense Metals news release dated March 30, 2021) the purpose of the scenario analysis is to evaluate the potential of multiple mine development scenarios through the completion of economic trade-off studies that will establish the basis for conducting a preliminary economic assessment (“PEA”).

Site visits for SRK resource and mining qualified persons (QP’s) have been scheduled for the 1st and 4th weeks of October 2021 to coincide with ongoing core drilling operations. SRK has now completed several key elements that will inform the scenario analysis including:

• Detailed data review (completed at sufficient detail to ensure no fatal flaws);

• Scenario definition (complete);

• Evaluation of mineral processing, hydrometallurgy and separation costs (complete);

• Pit optimization (complete); and

• Mine scheduling (in preparation).

The mine costing and economic modelling phases are subject to completion of the mine scheduling now underway. Subject to a successful scenario analysis, the PEA work will build on the scenario analysis, with the addition of further geology and resource review; process metallurgy Capex/Opex; infrastructure layout; wastewater management; social, environmental, and permitting aspects; marketing; economic analysis; and reporting.

Craig Taylor, CEO of Defense Metals, stated: “We are extremely pleased with the progress of the defined stages of the scenario analysis. Subject to successful results of the completed scenario analysis our goal is to be in a position to report our PEA to market by mid-November of this year.”
