Ucore Comments on G7 Focus to Secure Critical

Mineral Supply Chains, October 30–31, 2025

Company highlights policy tools—offtakes with price supports, strategic stockpiling, and

targeted financing—that could accelerate North American rare earth independence

Halifax, Nova Scotia - October 29, 2025 - Ucore Rare Metals Inc. (TSXV: UCU;

OTCQX: UURAF) (“Ucore” or the “Company”) issued the following statement regarding

the G7 Energy and Environment Ministers’ Meeting taking place in Toronto, Ontario,

October 30–31, 2025.

Public statements by governmen t officials ahead of the meeti ng indicate that ministers

intend to move beyond discussion toward concrete measures that strengthen allied

critical mineral supply chains. With partner s including the United States and Australia a

multilateral approach is the mandate . These measures include long -term offtake

agreements with price -support features, strategic st ockpiling, and targeted public

financing for mining, refining, and midstream processing - tools aimed at improving

market stability, enhancing security of supply, and catalyzing private investment across

the energy-transition value chain.

“We will see this week many examples of us moving beyond talks to firm commitments,”

said Canada’s Minister of Energy and Natural Resources in remarks previewing the

meeting.

What this means for Ucore shareholders

 Improved bankability & revenue visibility: Durable pricing frameworks and

government-backed offtakes can reduce commodi ty price volatility, narrowing

financing risk and improving the economics of North American rare earth refining.

 Faster path to domestic supply: Strategic stockpiles and procurement programs

can accelerate qualification cycles and enable earlier, larger -scale purchases of

high-purity rare earth oxides (REOs) by automakers, wind OEMs, and defense

supply chains.

 Reduced single-country risk: Coordinated G7 action to diversify supply reduces

exposure to concentrated sources for rare earth magnets and bat tery materials -

supportive of regional refining capacity and multi-source feedstock strategies.

“Rare earths are foundational to the clean energy transition and modern manufacturing,”

said Pat Ryan, P.Eng., Chairman & CEO of Ucore . “As policy frameworks take shape

to secure and decarbonize energy systems, Ucore is progressing North American refining

capacity designed to deliver high -purity rare earth oxides responsibly and at scale. We

see working with key allied Western world countries to achieve this objective as a priority.”
