DEFENSE METALS (DEFN.V): COMMENCES 2021 WICHEEDA RARE EARTH ELEMENT DEPOSIT RESOURCE EXPANSION AND DEFINITION DIAMOND DRILL PROGRAM

News Release – Vancouver, British Columbia – September 8, 2021:Defense Metals Corp. (“Defense Metals” or the “Company”) (TSX-V:DEFN / OTCQB:DFMTF / FSE:35D) is pleased to announce commencement of diamond drilling at its Wicheeda Rare Earth Element (REE) deposit. The Company plans to complete up to 5,000 metres of diamond drilling designed to expand the deposit and further delineate existing resources.

The road accessible Wicheeda REE Property 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].

During 2019, the Company completed 13 diamond drill holes totalling 2,005 metres that expanded the Wicheeda deposit to the north, where it remains open, and further delineated the relatively higher-grade, near surface dolomite carbonatite.  The 2019 drill campaign yielded one of the highest grade REE intercepts to date within drill hole WI19-31 that returned 4.43% LREO over 83 metres; including 5.47% LREO over a drill core interval of 33 metres ending in mineralization[2]. The 2019 exploration resulted in a 49% tonnage and 30% grade increase in mineral resources (see Defense Metals News Release Dated May 13, 2020).

The 2021 Wicheeda diamond drill program is designed to build on the successes of the 2019 campaign in support of future advanced economic studies. The 2021 drill program will focus on expanding the zone REE mineralized dolomite-carbonatite to the north, in addition to further delineating existing inferred resources within the central and northwestern areas of the deposit (Figure 1). A comprehensive campaign totalling 32 holes from seven drill pads ranging in depth from 75 to 225 metres over a 400 metre north-south strike extent is planned.

Craig Taylor, CEO of Defense Metals, stated: “Defense Metals is excited to commence its 2021 resource expansion and delineation diamond drilling at Wicheeda. We expect completion of the 2021 campaign will further solidify Wicheeda as one of the premier north American REE assets, and subject to a successful PEA, leave us well positioned to initiate further advanced economic studies.”

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.
