Defense Metals Advances Pre-feasibility Study

VANCOUVER, BC

,

Aug. 16, 2023

/CNW/ - Defense Metals Corp. ("

Defense Metals

" or the "

Company

")

(TSXV: DEFN) (OTCQB: DFMTF) (FSE: 35D) is pleased to provide a progress update with respect to its

2023 site infrastructure geotechnical investigations. The work, with support of the Defense Metals' technical

team and APEX Geoscience Ltd., is being completed by SRK Consulting (

Canada

) Inc. ("

SRK

") one of the

principal consultants for the preliminary feasibility study ("

PFS

") regarding the Company's Wicheeda Rare

Earth Element (REE) Project located near

Prince George, Canada

.

Craig Taylor

, CEO of Defense Metals, commented:

"It is great to see our technical consulting teams making significant headway with the Wicheeda

site investigations. Defence Metals has assembled a world class team of experts who have both

the experience and technical skills to bring this project through pre-feasibility."

The SRK geotechnical investigation includes the following scopes:

Geotechnical engineering

(waste rock, tailings, contact water pond, and site infrastructure

geotechnical investigation),

Tailings alternative assessment

prior to advancing into PFS-level design of a preferred alternative,

Geochemical characterization

(to support mine planning/waste management and to develop

preliminary water chemistry predictions for the main mine facilities).

The work completed to date included field site inspections from SRK personnel: Principial Consultant –

Mining Rock Mechanics,

Ed Saunders

, P.Eng. (waste storage facility geotechnical); Principal Consultant –

Geochemistry,

Kirsty Ketchum

, Ph.D., P.Geo. (metal leaching and acid/alkaline rock drainage geochemical

characterization); and Senior Consultant- Mining Rock Mechanics, Aton Bloem (open pit geotechnical).

Site infrastructure geotechnical investigations planned include a series of excavated test pits, and sonic

overburden drill holes designed to support the preliminary characterization of the shallow soil subsurface

and bedrock foundations of potential future waste rock storage (WSF), mineralization stockpile, contact

water pond (CWP), crusher, processing plant (INF), and tailings storage facility (TSF) locations.

To date a total of 13 excavated tests pits and 4 sonic overburden geotechnical holes for a total of 93

metres have been completed to characterize surficial material conditions within the proposed WSF, CWP,

and TSF areas (Images 1 and 2). Site geotechnical investigations encountered shallow overburden

conditions (nil or <1 metre overburden depth), excavated test pit depths ranging from 1 to 5 metres; and

sonic overburden drill holes in areas of thicker surficial material ranging from 7 metre to >36.6 metre depth

to bedrock.

SRK on site engineering consultants supervised the investigations and carried out soil geotechnical logging,

direct testing, sampling, photography of recovered materials, standpipe installation, and coordination of

laboratory testing. SRK will process the data collected from the sonic drilling and test pit investigations, and

laboratory testing results will be incorporated into the QA/QC dataset.

In addition to infrastructure geotechnical investigations, SRK has commenced a tailings alternatives

assessment prior to advancing into PFS-level design of a preferred alternative. This will include tailings

characterization and development of design criteria, a siting evaluation, and an alternatives trade-off.

As part of the geochemical characterization scopes SRK has completed a review and compilation of site

geological and geochemical data and drill core logs that have been acquired since the 2021 preliminary

economic assessment (PEA). These data will be used to develop a sampling plan of the existing drill core

for geochemical characterization of the proposed mine facilities, and future set-up of on-site kinetic leach

tests (barrel tests). Data will be interpreted to support mine planning/waste management and to develop

preliminary water chemistry predictions for the main mine facilities (source terms). Source terms are an

input to the site water and load balance model.

Excavated test pit and sonic overburden drilling is currently paused and is expected to resume as part of

the WSF, CWP, INF, and TSF (and TSF alternative) geotechnical investigations during September in

conjunction with the planned drilling of an additional four (4) pit geotechnical core holes totalling 820 metres.

Qualified Person

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. (B.C.), Principal and Consultant

of APEX Geoscience Ltd. of

Edmonton, Alberta

, who is a director of Defense Metals and a "Qualified

Person" as defined in NI 43-101.

About the Wicheeda REE Property

Defense Metals 100% owned, 6,759-hectare (~16,702-acre) Wicheeda Project is located approximately

80 km northeast of the city of

Prince George, British Columbia

; population 77,000. The Wicheeda REE

Project is readily accessible by all-weather gravel roads and is near infrastructure, including hydro power

transmission lines and gas pipelines. The nearby Canadian National Railway and major highways allow

easy access to the port facilities at

Prince Rupert

, the closest major North American port to

Asia

.

The 2021 Wicheeda REE Project Preliminary Economic Assessment technical report outlined a robust

after-tax net present value (NPV@8%) of

$517 million

and an 18% IRR

1

. This PEA contemplated an open

pit mining operation with a 1.75:1 (waste:mill feed) strip ratio providing a 1.8 Mtpa ("million tonnes per

year") mill throughput producing an average of 25,423 tonnes REO annually over a 16 year mine life. 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.
