DML Denison Mines Inc

Foremost Lithium Resource & Technology Ltd. (NASDAQ: FMST) (CSE: FAT) (“Foremost Lithium”, “Foremost” or the “Company”) is pleased to announce today that it has executed a property acquisition agreement (the “Option Agreement”) with Denison Mines Corp. (“Denison”), which grants Foremost an option to acquire up to 70% of Denison’s interest in 10 uranium exploration properties, along with other ancillary agreements (collectively, the “Transaction”). Pursuant to the Transaction, Foremost will provide Denison with consideration, including cash, stock, and/or future exploration spending commitments by Foremost. The Transaction is subject to regulatory approvals. In connection with the Transaction, Foremost intends to change its name to “Foremost Clean Energy Ltd.” Full details of the terms of the Transaction and the name change are outlined below under “Key Terms of the Transaction and Name Change”.

“We are pleased to announce a transformative transaction with Denison, a clear leader in the uranium sector. Uranium prices have seen significant strength in recent years driven by the global demand for clean energy, which has been reinforced by supportive government policies and geopolitical events underscoring the need for reliable western uranium supply. The Athabasca Basin is recognized as one of the world’s leading uranium jurisdictions, with numerous producing mines and high-profile development projects. This collaboration will advance significant near-term exploration and development efforts across numerous high-quality exploration projects to maximize the properties’ potential for the benefit of both Foremost and Denison shareholders,” stated Foremost’s President and CEO, Jason Barnard. Further, Barnard added, “On behalf of the entire team, I’d like to warmly welcome David Cates to our Board. As Denison’s current President and CEO, Mr. Cates will be an invaluable member adding his extensive experience and a proven track record in the Canadian uranium mining space. As a junior explorer, having the support of Mr. Cates and Denison will provide Foremost a competitive advantage. We are confident that Foremost is entering a new chapter of growth, and enhanced outcomes, for the benefit of both companies’ shareholders. We look forward to working with Mr. Cates as we steer and support our Company’s expansion towards its goal of being a new leading uranium explorer in the Athabasca Basin.”

David Cates, President and CEO, commented, “Denison is pleased to work with Foremost to enhance the potential for discovery on an excellent portfolio of uranium exploration properties that would otherwise receive little attention from Denison with our current focus on development and mining stage projects. We are impressed with Foremost’s leadership team and technical capabilities and are excited to see high-potential exploration work being carried out on these properties in the coming years.”

Transformational Transaction Covering High-Potential Uranium Properties

The project portfolio subject to the Option Agreement consists of 10 properties comprised of 45 claims covering an aggregate area of 332,378 acres (134,509 hectares) within the Athabasca Basin region of northern Saskatchewan (the “Exploration Properties”), which is known for its prolific history of large high-grade uranium discoveries and operating mines—currently producing ~20% of the world’s primary uranium supply1. Many of the Exploration Properties are proximal to some of the world’s highest-profile uranium operations, such as the McClean Lake mill and Cigar Lake mine, and consist of projects at different stages of exploration, from grassroots exploration to those with significant historical exploration and drill-ready exploration targets.

Generally, the most prospective exploration ground in the eastern portion of the Athabasca Basin is proximal to the Wollaston-Mudjatik Transition Zone (“WMTZ”) and has already been staked by existing uranium producers, developers, and explorers. As illustrated in Figure 1 below, the Transaction offers Foremost a unique opportunity to acquire a sizeable portfolio of well-situated properties (including several situated along the WMTZ) to facilitate a pivot towards a future focus on uranium exploration in a top jurisdiction.

Eastern Properties

Seven (7) of the Exploration Properties are situated within the Eastern portion of the Athabasca Basin region, in proximity to significant existing regional infrastructure, including: Murphy Lake South, Hatchet Lake, Turkey Lake, Torwalt Lake, Marten, Wolverine and Epp Lake (collectively, the “Eastern Properties”). Several of the Eastern Properties host previously identified uranium mineralization in geological settings similar to other known uranium discoveries. Historical drilling has focused primarily on unconformity targets, which provides Foremost further opportunity for continued exploration of potential basement style mineralization. Hatchet Lake is currently undergoing an active summer drilling and evaluation program, while several of the projects contain drill-ready targets from previously conducted exploration programs. The Eastern Properties are highlighted by the following projects:

• Murphy Lake South: conductive corridors that host significant high-grade uranium mineralization may extend onto the property; unconformity depth of ~350m
• Hatchet Lake: historical mineralization has been identified along the Richardson trend; uranium and base metal enrichment has also been encountered on the property with untested areas identified for follow up
• Torwalt Lake: Adjacent to the McClean Lake Operation and within 5km of multiple uranium deposits; potential to identify Key Lake or Collins Bay analogues

Blue Sky Properties

Three (3) of the Exploration Properties are located in the northwestern portion of the Athabasca Basin region (the “Blue Sky Properties”), representing an area of comparative under-exploration and high potential for new discovery, including Blackwing, GR and CLK, which encompass ~250,000 acres (101,634 hectares). These three projects are virtually unexplored. Holes drilled to date at CLK have intersected uranium mineralization, and regional geological surveys compiled by the Government of Saskatchewan indicate the potential for favourable geological settings for uranium mineralization at each property. The Blue Sky Properties are highlighted by the following:

• Blackwing and GR: both projects are situated on regional structures; Black Bay Fault and Grease River Shear – the Black Bay Fault hosts multiple Beaverlodge-style deposits in the Uranium City area
• CLK: only two historic drill holes are known to have been completed on the property, each of which intersected uranium mineralization, including CLG-D1 (up to 8,600 ppm U) and CLG-D5 (up to 510 ppm U)

Collaboration with Denison

Denison (TSX: DML) (NYSE American: DNN) is a leading Athabasca Basin-focused uranium mining, development, and exploration company. Denison’s current focus is advancing the Wheeler River project, which represents the largest undeveloped uranium mining project in the infrastructure rich eastern portion of the Athabasca Basin. Denison has a significant team of technical experts based in its office in Saskatoon, Saskatchewan, and this best-in-class team is ideal for supporting Foremost with its technical, operating and corporate initiatives. Upon completion of Phase 1 of the Option Agreement, Denison will be the largest shareholder of Foremost, holding ~19.95% of the shares outstanding and will retain an ownership interest in the Exploration Properties. Additionally, David Cates, President and CEO of Denison, is expected to join Foremost’s Board of Directors.

Foremost expects to act as project operator during the term of the Option Agreement and will conduct the exploration programs with its geological team led by Dahrouge Geological Consulting, under the guidance of Jody Dahrouge. Mr. Dahrouge has a long history of uranium exploration and discovery, which includes the generation of several projects on behalf of Strathmore Minerals Corp. and its successors, including the J Zone (now the Tthe Heldeth Túé deposit) on the Waterbury Lake property, the JR Zone on the Patterson Lake North property and the Triple R Zone at the Patterson Lake South property. As a past President and COO of Fission Energy Corp. (“Fission Energy”), Jody played a key role in the acquisition and exploration of Fission Energy’s exploration property portfolio, which culminated with the eventual acquisition of Fission Energy by Denison in 2013.

Key Terms of the Transaction

Under the terms of the Option Agreement, Foremost may acquire up to 70% of Denison’s interest in the Exploration Properties. Denison currently has 100% ownership in all of the properties except for Hatchet Lake, where Denison currently owns 70.15%, subject to a joint venture with Eros Resources Corp. In the case of Hatchet Lake, Foremost may earn up to a 51% interest in the joint venture, representing slightly over 70% of Denison’s current ownership interest. The Option Agreement outlines three (3) phases, as summarized below:

Phase 1:	To earn an initial 20% interest in the Exploration Properties (14.03% for Hatchet Lake), on or before October 7, 2024 (the “Effective Date”), Foremost’s obligations include: Issuing 1,369,810 of the Company’s common shares (the “Common Shares”) to Denison; Appointing one director to Foremost’s Board of Directors immediately on the Effective Date; Appointing a Technical Advisor to Foremost at Denison’s election; and Entering into an Investor Rights Agreement providing for, among other things: The appointment by Denison of up to two (2) individuals to the board of directors of Foremost; and  A pre-emptive equity participation right to invest in Foremost’s Common Shares to maintain its 19.95% interest.
Phase 2:	To earn an additional 31% interest in the Exploration Properties (21.75% for Hatchet Lake), on or before 36 months following the Effective Date, Foremost’s obligations include: Paying $2,000,000, in cash or Common Shares or a combination thereof, at the discretion of Foremost to Denison; and Incurring $8,000,000 in exploration expenditures on the Exploration Properties. If the conditions of Phase 2 are not satisfied, Foremost shall forfeit its interests in and rights to the Exploration Properties.
Phase 3:	To earn an additional 19% interest in the Exploration Properties (15.22% for Hatchet Lake), on or before 36 months following the successful completion of Phase 2, Foremost’s obligations include: Paying $2,500,000, in cash or Common Shares or a combination thereof, at the discretion of Foremost to Denison; and Incurring $12,000,00 in exploration expenditures on the Exploration Properties. If the conditions of Phase 3 are not satisfied, Foremost shall forfeit a portion of its interests in and rights to the Exploration Properties such that Denison’s interests in the Exploration Properties will be increased to 51% and operatorship shall revert to Denison.

Upon the successful completion of the Option Agreement, the parties would enter into a formal joint venture agreement in respect of the Exploration Properties where the initial ownership interests of Foremost and Denison will be determined based on satisfaction of conditions pursuant to the Option Agreement.

Uranium Overview

The global clean energy transition has increased the need for alternative fuel sources with nuclear power prevailing as a crucial component to meet the demand for a green economy. “Market sentiments on uranium are positive including equity markets, and particularly look favourable for uranium developers” wrote Sehaj Anand, a research analyst for FactSet (What’s Driving the Bull Run in Uranium, May 2024). The commodity price rose above US$100/lb U3O8 last year, the highest since 2007, after a decade-long decline from US$143/lb U3O8 to US$18/lb U3O8 and is currently sitting at ~US$80/lb U3O8.

Uranium: Supply vs Demand

The supply side’s future outlook is forecasted to underserve the demand side. Some of the factors contributing to an increase in the demand for uranium globally include: the desire to phase out dependence on fossil fuels, depressed uranium prices over the past decade and mine closures and/or disruptions. Trade sanctions on Russia are affecting enriched uranium supply to the West and civil unrest in Niger have sparked a global urgency to secure reliable sources of uranium.

Most recently, uranium producers, developers, and physical uranium holding companies have continued to buy physical uranium, putting a further strain on the uranium supply. With the scarcity of nuclear fuel, there is a growing sense of urgency to secure sufficient uranium supply, adding additional pressure on the overall uranium market 2.

Market Outlook

Nuclear energy has the lowest carbon footprint for power generation compared to any other source and is the most reliable option for carbon-free baseload electricity generation3. At the 2023 United Nations Climate Change Conference or Conference of the Parties of the UNFCCC (more commonly known as COP 28), a total of 22 countries agreed to target tripling nuclear capacity by 2050 as countries focus on energy security and affordability. The biennial Nuclear Fuel Report said demand for uranium is expected to rise to 83,840 tonnes by 2030 and 130,000 tonnes by 2040, from 65,650 in 2023.4

Name Change

With Foremost’s business activities to be focused on exploration efforts to discover source fuel for clean energy solutions, including both uranium and lithium, the Board of Directors have unanimously agreed to change the Company’s name to “Foremost Clean Energy Ltd.” Foremost will continue trading under the same symbols, “FMST” as listed on the Nasdaq, and “FAT” as listed on the CSE, subject in each case to regulatory approval. The CUSIP number assigned to the Company’s shares following the name change will be CUSIP (34546R100) and ISIN (CA34546R1001).

The CSE will publish a bulletin announcing the effective date of the change in Foremost’s name. The Company’s common shares are anticipated to commence trading on both the CSE and Nasdaq under its new name and CUSIP number at market open on or about Sept 27, 2024. No action is required to be taken by shareholders with respect to the name change. Outstanding share certificates are not affected by the name change and do not need to be exchanged.
