Denison Mines Corp. (DNN) - Canvas Business Model: Key Activities

You're looking at the core actions Denison Mines Corp. is driving right now to move from developer to producer. It's all about execution on the ground and navigating the final hurdles for Phoenix.

The primary focus is pushing the flagship Wheeler River Project through its final stages. This involves intense engineering work and the critical regulatory sign-off process that dictates the construction start date.

• Advancing Phoenix In-Situ Recovery (ISR) mine detailed engineering: 85% complete.
• Navigating the final Canadian Nuclear Safety Commission (CNSC) regulatory hearings: Part 2 held from December 8 to 11, 2025.
• Uranium production at McClean North via the SABRE mining method: Commercial mining commenced in July 2025.
• Managing a portfolio of Athabasca Basin exploration properties: Direct ownership interests cover approximately 384,000 hectares.
• Strategic procurement of long-lead capital items: Over C$67 million committed as of Q1 2025.

The McClean North operation is already generating cash flow, which is a major differentiator for a developer at this stage. For Q3 2025 alone, 85,235 pounds of U3O8 were produced (Denison's share: 19,178 pounds of U3O8), achieving an impressive initial operating cash cost of approximately US$19 per pound U3O8.

The regulatory path for Phoenix is nearing its end. After receiving the Province of Saskatchewan's Environmental Assessment (EA) approval in July 2025, the focus shifted to the federal CNSC hearings, with the final part concluding in December 2025. The company is positioning for a construction start in early 2026, targeting first production by the first half of 2028.

Here's a quick look at the scale of the assets Denison is managing:

The procurement activity is directly tied to getting Phoenix ready to build. By the end of Q1 2025, Denison had already funded over $7 million and committed the specified C$67 million for those crucial, long-lead capital purchases. This proactive spending, alongside holding 2.2 million pounds U3O8 in physical inventory and carrying no debt, keeps the pre-Final Investment Decision (FID) work funded.

The exploration portfolio management involves maintaining a significant land position and managing interests in other key deposits through the JCU (Canada) Exploration Company, Limited structure. For instance, the Millennium project holds a 30.099% JCU interest, Kiggavik is at 33.8118% JCU interest, and Christie Lake is at 34.4508% JCU interest.

The SABRE mining method at McClean North is a key operational activity, having started in June/July 2025. By the end of Q3 2025, 2,063 tonnes of high-grade ore (100% basis) had been extracted from McClean North.

Denison Mines Corp. (DNN) - Canvas Business Model: Key Resources

You're looking at the core assets Denison Mines Corp. brings to the table right now, the things that underpin their entire operation as they move toward production. Honestly, it's a mix of ownership stakes, specialized know-how, and a very healthy war chest built up over the last few years.

The company's primary value driver is its stake in the Wheeler River Project. Denison holds an effective 95% interest in this flagship asset, which is the largest undeveloped uranium project in the eastern Athabasca Basin region. This project hosts both the Phoenix deposit, planned for In-Situ Recovery (ISR) mining, and the Gryphon deposit, slated for conventional underground mining. The Phoenix ISR mine engineering is at an exceptionally advanced stage, reaching nearly 85% completion as of late 2025, positioning them to potentially start construction in early 2026 following regulatory approvals.

Another critical piece of infrastructure is their ownership in the McClean Lake uranium mill. Denison maintains a 22.5% ownership interest in the McClean Lake Joint Venture (MLJV), which includes this mill, one of the largest processing facilities globally. This ownership provides essential downstream processing capability, which is already being utilized, as the mill is currently processing ore from the Cigar Lake mine under a toll milling agreement.

Denison Mines Corp. also possesses proprietary expertise in high-grade ISR mining technology, specifically demonstrated by the development path chosen for the Phoenix deposit. This technical capability is key to unlocking value from their high-grade resources using a method that differs from traditional mining in the Basin. The company is also leveraging patented technology at McClean Lake, where the SABRE mining method commenced commercial production at the McClean North deposit in 2025.

Financially, Denison is in a strong position to fund its near-term objectives. As of the end of the third quarter of 2025, the company reported total cash, investments, and uranium holdings of nearly $720 million (CAD), significantly bolstered by a convertible notes issuance in August 2025.

Here's a quick summary of those core physical and financial anchors:

Beyond the main assets, the resource base includes other strategic interests that feed into their long-term optionality:

• Direct land position covering approximately ~384,000 hectares in the Athabasca Basin region as of December 31, 2024.
• Interests in other joint ventures through its 50% ownership of JCU (Canada) Exploration Company, Limited.
• Initial ownership interests in new joint ventures adjacent to Wheeler River, including up to 70% earn-in potential at Wheeler North.
• The McClean Lake mill has a licensed annual production capacity of 24.0 million pounds U3O8.

The company's ability to hold onto its physical inventory, reported at 2.2 million pounds U3O8 as of Q1 2025, is a testament to that strong balance sheet, allowing them to avoid selling strategic inventory to fund development. Finance: draft 13-week cash view by Friday.

Denison Mines Corp. (DNN) - Canvas Business Model: Value Propositions

You're looking at the core reasons why Denison Mines Corp. (DNN) believes its Phoenix deposit, part of the Wheeler River Project, stands out. Honestly, for a company in the development stage, these value propositions are everything; they are the foundation for future cash flow.

The primary draw is the projected cost structure for future production. Denison Mines Corp. is positioning the Phoenix In-Situ Recovery (ISR) operation to be among the world's lowest-cost producers. This is grounded in the feasibility study (FS) data, which underpins the value proposition.

• Ultra-low-cost future production at Phoenix (projected all-in cost US$25.78/lb U3O8).
• Potential for rapid payback (Phoenix projected at 10 months).

That 10 months payback period is incredibly fast for a major mining project, which is a huge differentiator. Here's a quick look at the economics supporting that speed, based on the June 2023 FS for the Phoenix deposit, where Denison holds an effective 95% interest:

The method itself is a key value driver. Denison Mines Corp. is aiming for the first-mover advantage with Canadian high-grade ISR mining. This method, In-Situ Recovery, is less invasive and, crucially, is expected to deliver those low operating costs by processing ore in place, a technique not yet widely proven at this scale in the Athabasca Basin.

The resource base itself offers inherent value. You're looking at high-grade uranium deposits in the politically stable Athabasca Basin. The Zone A high-grade domain alone is estimated to contain 56.3 million pounds U3O8 in Measured and Indicated mineral resources, at an average grade of 46.0% U3O8 as of the June 2023 estimate. This grade profile is what allows for such competitive cost estimates.

Finally, the external market positioning is about security of supply. Denison Mines Corp. offers a reliable, long-term supply of zero-carbon nuclear fuel for utilities. The company also holds a 22.5% ownership stake in the McClean Lake uranium mill, which has licensed capacity to process ore, providing a crucial processing pathway for its own production and for toll milling agreements, such as the one with Cigar Lake. To be fair, the company has been active in securing social license, signing an Impact Benefit Agreement with the Métis Nation-Saskatchewan in December 2025, which helps secure the path forward for the Wheeler River Project.

Denison Mines Corp. (DNN) - Canvas Business Model: Customer Relationships

You're looking at how Denison Mines Corp. manages its critical external relationships, which are foundational to advancing its Athabasca Basin projects. This isn't about selling widgets; it's about securing operational partnerships and community consent for multi-decade uranium assets.

Strategic, long-term contracts with global nuclear utility companies.

Denison Mines Corp. is positioning its projects, particularly the flagship Wheeler River Project, to become a future low-cost producer, which is the core appeal to utility fuel buyers. While specific long-term sales contracts aren't detailed in recent filings, the company is actively engaging the market. For instance, CEO David Cates discussed the rationale behind their financing and project status with fuel buyers at the World Nuclear Symposium in September 2025. The McClean Lake Joint Venture (MLJV), where Denison holds a 22.5% interest, is already producing, with the McClean Lake mill processing ore from the Cigar Lake mine under a toll milling agreement. This existing operational relationship demonstrates a pathway for future off-take agreements.

The progress on the Phoenix ISR mine at Wheeler River is key to securing these future utility relationships. As of Q3 2025, engineering for the Phoenix ISR mine was 85% complete, with the company aiming for first production by mid-2028. The company's strong financial position, bolstered by the US$345 million convertible senior notes issuance in August 2025, means they can fund pre-Final Investment Decision expenditures without needing to pre-sell material under duress.

Direct engagement with Indigenous communities for project support.

Securing social license to operate is a primary focus, evidenced by major recent agreements. Denison Mines Corp. signed the Nuhenéné Benefit Agreement, a regional mutual benefits agreement, in early December 2025. This agreement provides consent and support for the development and operation of the Wheeler River, Waterbury Lake, Midwest, and McClean Lake projects. The negotiations for this landmark deal began following an exploration agreement signed in 2022.

The relationship involves several key entities:

• The Ya'thi Néné Land and Resource Office (YNLR).
• Three Denesułiné First Nations: Hatchet Lake, Black Lake, and Fond du Lac.
• Four Northern Municipalities: Stony Rapids, Uranium City, Wollaston Lake, and Camsell Portage.

The agreement includes provisions for environmental oversight, Woodland Caribou protection, surface water monitoring, and benefit-sharing from project operations. This formalizes a commitment to balancing development with traditional values.

Investor relations focused on de-risking and project milestones.

Denison Mines Corp. maintains a transparent relationship with its capital providers by consistently reporting on operational and regulatory achievements. The company ended Q3 2025 with nearly $720 million in total cash, investments, and uranium holdings. This robust balance sheet, which includes 2.2 million pounds U3O8 in physical holdings, is used to signal financial control to the market. Key milestones reported to investors in 2025 include:

• July 2025: Ministerial approval from the Province of Saskatchewan for the Wheeler River Environmental Assessment (EA).
• June 2025: Commencement of uranium mining operations at the McClean North deposit using the SABRE method.
• October 2025: Commencement of the Canadian Nuclear Safety Commission public hearing for Federal EA and construction license.

The successful US$345 million convertible notes offering in August 2025 was positioned as funding execution of the Phoenix project, not as a necessity due to financial distress.

Maintaining relationships with joint venture partners like Orano.

The relationship with Orano Canada is central to Denison Mines Corp.'s current production. Orano Canada operates the McClean Lake Joint Venture (MLJV), holding a 77.5% interest, while Denison holds 22.5%. This partnership successfully commissioned and ramped up production at the McClean North mine using the patented Surface Access Borehole Resource Extraction (SABRE) mining method, which began in June 2025.

Here's a quick look at the MLJV structure and recent output:

This operational collaboration is a tangible example of a working, revenue-generating relationship that supports Denison's overall business model. Also, Denison holds a 25.17% interest in the Midwest Joint Venture, also with Orano as a partner.

Finance: review Q4 cash position against $720 million total cash/holdings figure by end of January.

Denison Mines Corp. (DNN) - Canvas Business Model: Channels

You're looking at how Denison Mines Corp. gets its product-or the potential for its product-to the market as of late 2025. The channels here are heavily weighted toward joint venture operations and strategic asset holding, given the flagship Phoenix project is still in the final regulatory stages.

Direct sales agreements with nuclear utility end-users.

While the ultimate goal is securing long-term offtake agreements for production from the Wheeler River Project's Phoenix ISR mine, the current revenue-generating channel relies on processing services.

Denison Mines Corp. (DNN) - Canvas Business Model: Revenue Streams

You're looking at how Denison Mines Corp. (DNN) is bringing in cash right now, which is a mix of processing fees and early production, given they are still in a major development phase. Honestly, for a company focused on building its next big mine, these revenue streams are crucial for keeping the lights on and funding the path to full production at Phoenix.

The revenue streams are anchored by existing infrastructure and the very recent start of operations at McClean North. Here's a breakdown of the key components that made up their income as of late 2025:

The most consistent, non-development-related income comes from processing services. This is the toll milling arrangement at the McClean Lake mill, which is utilizing capacity processing ore from the Cigar Lake Joint Venture (CLJV).

The start of production at McClean North is a significant shift, moving Denison from purely service/holding revenue to operational sales. This production is processed at the McClean Lake mill under the McClean Lake Joint Venture (MLJV) structure.

• Revenue from McClean North production (DNN Share): 19,178 pounds U3O8 in Q3 2025.
• Total McClean North production for Q3 2025 (100% basis): 85,235 pounds U3O8.
• Initial operating cash cost for this production was approximately US$19 per pound U3O8.

The Ecora deal is an accounting item that ties up future cash flows. You need to keep an eye on this liability as it directly impacts future cash available to Denison, even though it isn't recognized as current period revenue in the same way as the toll milling fee.

• Recognition of deferred revenue from the Ecora deal is tied to the ongoing toll milling of CLJV ore.
• The associated long-term obligation, the Deferred Revenue Liability, stood at $32.4 million as of Q3 2025.
• Denison also recorded accounting accretion expense on this deferred revenue balance, such as $678,000 in Q1 2025.

While not a recurring operational revenue stream, the value of their physical uranium holdings represents a potential source of capital or strategic sales, which can be realized depending on market conditions and corporate needs. This is a key asset that bolsters their balance sheet.

• Physical uranium holdings value as of end of Q1 2025 was approximately CAD$204 million.
• This Q1 2025 physical inventory was valued at approximately US$64.45 per pound U3O8.
• The average cost basis for these long-term holdings was USD$29.66 per pound U3O8.

So, you see the revenue picture is currently supported by the established tolling agreement, which is being accounted for with associated deferred revenue movements, and the very new, but important, initial production from McClean North. Finance: draft 13-week cash view by Friday.
