Defense Metals Diamond Drilling Update - Pit Slope Geotechnical Preparations Underway

VANCOUVER, June 17, 2022 - Defense Metals Corp. ("Defense Metals" or the "Company") (TSX-V: DEFN) (OTCQB: DFMTF) (FSE: 35D) is pleased to provide an update for ongoing diamond drilling at its Wicheeda Rare Earth Element (REE) deposit. The 2022 diamond drilling campaign commenced in the northern resource area with the first two resource delineation drill holes totalling approximately 615 metres now nearing completion.

The initial two drill holes were collared from the same site oriented southwest at -50 and -60 degree dips. The holes are designed to establish the eastern carbonatite contact near surface, and for the purpose of resource infill near 2021drill hole WI21-33 that yielded 3.17% TREO over 196 metres; including 4.29% TREO over 55 metres¹ at depth that expanded high-grade REE mineralization beyond the mineral resource pit shell. Both holes intersected significant intervals of visually REE mineralized dolomite carbonatite between as predicted by the geological model (Image 1).

As announced in its June 7, 2022, drilling commencement news release, the Company plans to complete up to 5,000 metres of diamond drilling designed to further delineate existing resources, assess near deposit exploration targets, collect geotechnical and hydrogeological drilling for the purpose of optimization of open pit slope design, and generate additional REE mineralized material for continued metallurgical testwork.

Kristopher Raffle, P.Geo., Director and QP of Defense Metals commented: "With the second drill hole of our 2022 resource infill campaign nearing completion, we look forward in the coming days to initiating co-purposed infill and pit slope geotechnical drill holes in the main deposit and PEA mine schedule pit highwall areas, in addition to continuation of pad building for planned exploration holes. With 2022 drilling operations once again based at the Wicheeda Deposit site field camp, we expect to be able to take advantage of logistical efficiencies; most notably a reduction on helicopter utilization."

The Company attended the Prospectors & Developers Association of Canada Convention (PDAC) in Toronto, Ontario from June 13, 2022 to June 15, 2022 and met with several industry stakeholders including shareholders, investment firms, and strategic industry companies.

Defense Metals recently staked additional mineral claims contiguous to the Wicheeda REE Property. The 100% owned Wicheeda REE Property is now 4,244-hectares.

Further to the Company's news release dated May 24, 2022, the Company paid US$100,000 to Digitonic Limited, an arm's-length party to provide investor relations services and to provide content creation, digital and video marketing services.

The 100% owned 4,244-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 near infrastructure, including power transmission lines, the CN railway, and major highways.

The Wicheeda REE Project yielded a robust 2021 PEA that demonstrated an after-tax net present value (NPV@8%) of $517 million, and 18% IRR². A unique advantage of the Wicheeda REE Project is the production of a saleable high-grade flotation-concentrate. The PEA contemplates a 1.8 Mtpa (million tonnes per year) mill throughput open pit mining operation with 1.75:1 (waste:mill feed) strip ratio over a 19 year mine (project) life producing and average of 25,423 tonnes REO annually. 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.

The scientific and technical information contained in this news release as it relates to the Wicheeda REE Project has been reviewed and approved by Kristopher J. Raffle, P.Geo. (BC) Principal and Consultant of APEX Geoscience Ltd. of Edmonton, AB, a director of Defense Metals and a "Qualified Person" as defined in NI 43-101. Mr. Raffle verified the data disclosed which includes a review of the sampling, analytical and test data underlying the information and opinions contained therein.
