Since

the

December 2023

start

of

the demonstration program,

Ucore has operated and

continuously improved its 52

-

Stage RapidSX

™

Demonstration Plant (“

Demo Plant

”) within

the Company’s

Kingston, Ontario, Commercialization and Demonstration Facility

(“

CDF

”)

.

This work is dedicated to transitioning

the Company’s

RapidSX

™

separation

technology to

its

under

-

construction

Louisiana

Strategic Metals Complex (“

SMC

”)

in Alexandria, Louisiana.

The

Louisiana

SMC is

a

developing

REE separation and oxide production facility focused on

the production

of

mid (

Sm

Eu

Gd

) and heavy (

initially

Tb

and

Dy,

potentially

followed by

Y

,

which is in high demand

) rare earth elements

with the ability to also produce an

NdPr

rare

earth oxide (“

REO

”) product.

The CDF work has focused on the

precise

manipulation of tonnes of a heavy mixed

rare

-

earth oxide derived from a US

-

friendly feedstock resource through

the

series of RapidSX

™

splits

shown in Figure 1

.

These splits represent the

groups and products for the Louisiana SMC

,

and in every case have been directly compared to a 52

at the CDF

for direct purity and recovery comparisons.

Ucore’s a

dvancements

; adverse capital

-

market conditions; unexpected due

-

diligence findings; the
