Defense Metals Completes Successful Phase I Pilot Plant

Work

VANCOUVER, BC

,

April 12, 2023

/CNW/ - Defense Metals Corp. ("

Defense Metals

" or the "

Company

") (TSXV: DEFN)

(OTCQB: DFMTF) (FSE: 35D) is pleased to announce that the Phase I of its hydrometallurgical pilot plant at SGS

Lakefield has been successfully completed.

John Goode

, Consulting Metallurgist to Defense Metals and who attended the pilot plant, commented:

"This first fully integrated pilot plant demonstration of the proposed Wicheeda hydrometallurgical process

delivered exactly what was required of it. We have confirmed the general workability of the process, optimized

certain design parameters, and identified areas that will be improved ahead of the Phase II pilot plant. The SGS

Lakefield team did an excellent job of construction and operation of the circuit, and their efforts are much

appreciated."

The main objective of Phase I of the pilot plant was to test the flowsheet for operability and identify any changes that might

be required before a longer test campaign. During the five days of continuous operation, the parameters for the various unit

operations were varied slightly to allow optimization of the circuit ahead of the Phase II pilot plant run scheduled for

late-

April 2023

.

Assays are still being received and evaluation of the results has not yet been finalized. However, to date it can be reported

that the extraction of Pr (praseodymium) and Nd (neodymium) from the acid bake calcine was in excess of 90%, the

impurity removal circuits were very efficient, and reagent regeneration and water recirculation were effective. Minor

changes will be made to the circuit ahead of Phase II and an alternative product precipitant will be used.

Methodology

The fully integrated Pilot Plant included sulphuric acid baking, water leaching, three stages of impurity removal, rare earth

precipitation, magnesia regeneration and recycling, and process water recycle. The plant ran continuously and without

interruption for 24 h/day over a total run time of 110 hours. Operations were handled by a total of ten SGS technicians and

metallurgists on each of two shifts managed by senior day-shift staff.

About the Wicheeda REE Property

Defense Metals 100% owned, 4,262-hectare (~10,532-acre) Wicheeda Light REE property 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 ("PEA") 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.
