DEFENSE METALS (DEFN.V): REVALUATES ITS ATHABASCA BASIN URANIUM PROJECTS

News Release – Vancouver, British Columbia – September 23, 2021:Defense Metals Corp. (“Defense Metals” or the “Company”) (TSX-V:DEFN / OTCQB:DFMTF / FSE:35D) is pleased to announce that in light of renewed and sustained uranium interest which has driven uranium spot prices to multi-year highs, it has commenced an updated internal technical review of its Athabasca Basin uranium project holdings.

During 2018, Defense Metals acquired 100% of the Geiger North and Klaproth projects for a combination of cash and share payments; with Geiger North being subject to a 2% net smelter return royalty. The projects comprise a total of five mineral claims totalling 9,363 hectares (ha) located in the northeast Athabasca Basin, with the Geiger North claims (1,233 ha) being in good standing until summer-fall 2022, and Klaproth (8,130 ha) in good standing until early 2023.

The Geiger North and Klaproth projects are located approximately 35 kilometres northwest of the McClean Lake mine and mill, in a relatively under-explored area of the Athabasca Basin adjacent to the Wollaston-Mudjatik transition zone – a major crustal suture related to most of the major uranium deposits in the eastern Athabasca Basin.

The Geiger North and Klaproth projects are surrounded by multiple major mining companies, giving the company a strategic foothold in a proven and prolific uranium mining district.

Uranium mineralization in the northeast Athabasca Basin and vicinity of the Geiger and Klaproth projects is typically associated sheared graphitic-gneiss basement rocks that present as prominent conductive anomalies. Defense Metals is currently initiating an updated review of historical exploration (diamond drilling, ground, and airborne magnetic and electromagnetic geophysical, and geochemical surveys) completed within the projects. The expectation is that results of the data review will form the basis for go-forward justification for renewed exploration up to and including commissioning of project wide airborne electromagnetic geophysical surveys to identify prospective basement conductive anomalies.

Craig Taylor, CEO of Defense Metals, stated: “The renewed interest in uranium has prompted Defense Metals to reassess its considerable land position in the prolific northeast Athabasca Basin. While the Company’s focus remains on advancing it flagship Wicheeda REE Deposit near Prince George, British Columbia, we look forward to further capitalizing on the shareholder value  brought by the Geiger North and Klaproth Projects.”
