planning a complete domestic U.S. supply chain for advanced graphite materials, is pleased to announce the closing of a

strategic investment from Doyon Limited and Aleut, both Alaska Native corporations, for aggregate gross proceeds of

Each Unit consists of one common share (a "

Warrant entitles the warrant holder to acquire one Common Share of the Company at a price of CDN$1.03 per Common Share expiring

three (3) years from the closing of the private placement and includes participation rights on future financings so long as the Warrants

remain outstanding. The Company has received conditional approval for this private placement from the TSX Venture Exchange and the

private placement is subject to final approval of the TSX Venture Exchange. All securities issued in connection with this private

placement will have a restricted period that expires four months and one day following the date of issuance.

Gross proceeds from the private placement will be used to conduct environmental studies and other permitting related activities on the

Graphite Creek property, and for general corporate purposes. There were no finder or broker fees paid in connection with the private

placement.

"For

Doyon

, this is not just an investment in Graphite One, it is a long-term investment in

Alaska

," said

Aaron Schutt

, President and

CEO of Doyon Limited. "With decades of experience in responsible resource development,

Doyon

looks forward to working with

Graphite One to bring the Graphite Creek Critical Minerals Project into production."

"This investment reflects Aleut's belief in renewable energy. Graphite is a critical resource in building that future and we believe

Graphite One shares in our commitment for responsible development," said Skoey Vergen, CEO & President of Aleut. "Not only does

this create value for our shareholders, it opens up the potential for future opportunities in

Alaska

that could benefit our region".

"All of us at Graphite One are grateful for these investments from

Doyon

and Aleut Corp, joining Bering Straits Native Corporation,

which made its strategic investment in G1 in 2023. We are pleased and honored to be the first Critical Mineral project to have direct

investment from three Alaska Native Regional Corporations" said Anthony Huston, President and CEO of Graphite One. "We greatly

appreciate the trust placed in us through these partnerships, together with your support, seek to make Graphite Creek a model of

responsible development that brings long-term benefits to your communities and the

State of Alaska

."

Graphite One's Supply Chain Strategy

The Project is planned as an integrated business operation to produce lithium-ion battery anode materials and other graphite products

for the U.S domestic market on a commercial scale using primarily natural graphite from

Alaska

. The Project combines the operation of

an advanced graphite manufacturing facility to be located in

Warren Ohio

, subject to financing, with the supply of natural flake graphite

from the Company's proposed Graphite Creek Mine in

Alaska

. The resources associated with the Company's Alaska State mining

claims were cited by the U.S. Geological Survey in

January 2022

as America's largest natural graphite deposit[1], and in 2023, "as

among the largest in the world." This precedes the FS-verified significant increase in the size of the deposit. The Company entered into

two non-binding letters of interest with the EXIM Bank in

September 2025

and 2024 for up to

$895 million

in loans to fund the

development of the Graphite Creek mine and the construction of the

Ohio

manufacturing facility.
