Foremost Clean Energy Completes First Phase of Option

Agreement with Denison Mines for Interests in 10 Uranium

Properties in the Athabasca Basin

Denison becomes Foremost’s largest shareholder at 19.95%

VANCOUVER, British Columbia, October 07, 2024 -- Foremost Clean Energy Ltd.

(NASDAQ: FMST) (CSE: FAT) (“Foremost Clean Energy”, “Foremost” or the “Company”),

an emerging North American uranium and lithium exploration company, is pleased to

announce today that, further to its announcement of September 23, 2024 , it has now

completed Phase One of its transaction (the “ Transaction”) with Denison Mines Corp.

("Denison"), acquiring 20% of Denison’s interest (the “Phase One Interest”) in 10 uranium

exploration properties covering over 330,000 acres in the Athabasca Basin in Northern

Saskatchewan (the “Exploration Properties”). In addition to other considerations, Denison

was issued from treasury 1,369,810 common shares in the capital of Foremost (the

“Common Shares”).

Jason Barnard President and CEO of Foremost, stated, “We are pleased to officially close

the first phase of this transformational transaction, marking a significant milestone for

Foremost and its shareholders. The Company is fortunate to acquire an interest in a

large portfolio of ten prospective projects situated amongst well -established

infrastructure, mills and operating mines. With David Cates joining our Board of

Directors, we also have the advantage of Denison’s support and David’s significant

experience leading a highly successful advanced uranium developer in the Athabasca

Basin.” Barnard continue d, “ We appreciate that Denison has put its trust and

confidence in our Company and are excited to collaborate on the rapid advancement

of exploration on these properties at a time when the nuclear energy sector is seeking

additional sources of future uranium supplies. With Denison’s additional guidance and

support on technical and operating matters, we feel well positioned for future

success.”

The acquisition was completed pursuant to an option agreement with Denison dated

September 23, 2024 (the “ Option Agreement ”), which granted Foremost the option to

acquire, through three phases, up to 70% of Denison’s interest in the Exploration Properties.

In addition, concurrent with the acquisition of Phase One Interest, Foremost has also:

• Appointed Mr. David Cates, the President and CEO of Denison, to Foremost’s board

of directors ; Mr. Cates has extensive expertise in the Canadian and international

uranium mining industry from over a decade of senior management and financial

experience in various roles with Denison;

• Appointed Andy Yackulic, Denison’s Vice President of Exploration, to its advisory

board as a technical and geoscientific advisor. Mr. Yackulic has spent the past two

120190907v1

decades of exploration focused in the Athabasca Basin region acquiring extensive

experience with various geologic models for uranium mineralization, and has been

working with Denison since 2020. Previously, he spent 12 years at Cameco

Corporation in various roles and led the exploration team that discovered the Fox

Lake uranium deposit. Mr. Yackulic holds a Bachelor of Science in Geology from the

University of Saskatchewan, is a member of the Association of Professional

Engineers & Geoscientists of Saskatc hewan (APEGS), and is a Qualified Person in

accordance with the requirements of National Instrument 43 -101 – Standards of

Disclosure for Mineral Projects;

• Entered into an investor rights agreement with Denison; and

• Become the operator of the Exploration Properties.

The Exploration Properties are comprised of 45 claims covering an aggregate area of 332,378

acres (134,509 hectares) within the Athabasca Basin region of northern Saskatchewan,

which is known for its prolific history of large high-grade uranium discoveries and operating

mines—currently producing ~15% of the world’s primary uranium supply.

Denison Mines is responsible for discovering several high -profile uranium deposits and is

currently the operator of the Phoenix and Gryphon deposits at Wheeler River and the THT

deposit at Waterbury Lake in the Athabasca Basin. With Denison’s primary focus on

development and mining stage projects , this excellent portfolio of uranium exploration

properties would otherwise receive limited attention. Many of the properties in the portfolio

are proximal to some of the world’s highest -profile uranium operations, such as the

McClean Lake mill and Cigar Lake mine and span from grassroots exploration to hosting

drill-ready exploration targets . Foremost will now be able to provide the Exploration

Properties with increased attention and thus improve the prospect of discovery.

documents in connection with the Transaction, please refer to the Company’s filings under

its profile on Sedar+ at www.sedarplus.ca and on Edgar at www.sec.gov/edgar.shtm. All

Common Shares issued to Denison pursuant to the Option Agreement will be subject to a

statutory four-month hold period pursuant to applicable Canadian securities laws.
