Key Terms

in-situ recovery, environmental assessment, construction licence, joint venture, +1 more

5 terms

in-situ recovery technical

"Environmental Assessment approval granted by the Province of Saskatchewan for the Phoenix In-Situ Recovery uranium mine"

In-situ recovery is a mining method that extracts a valuable material by dissolving it underground and pumping the solution to the surface instead of digging or blasting rock. For investors, it matters because this approach often lowers upfront construction costs, shortens development time and reduces visible land disturbance, but it also brings regulatory, environmental and groundwater risks that can affect project timelines, operating costs and valuation.

environmental assessment regulatory

"related to the Environmental Assessment approval granted by the Province of Saskatchewan"

An environmental assessment is a process that evaluates how a project or activity might impact the natural surroundings, such as air, water, land, and wildlife. It helps identify potential environmental risks and ensures that any negative effects are managed or minimized. For investors, this assessment provides insight into the sustainability and long-term viability of projects, which can influence their financial decisions and risk management.

construction licence regulatory

"approval of the Project's EA and the grant of the construction licence by the Canadian Nuclear Safety Commission"

A construction licence is an official government or municipal permit that authorizes a company to build, expand or alter a physical project, often with specific conditions, inspections and time limits. For investors it matters because the licence controls whether and when a project can proceed, affects costs and timelines, and creates legal risk—similar to needing a permit before starting a major renovation, without which the project can be delayed, fined or stopped.

joint venture financial

"and is a joint venture between Denison (90% and operator) and JCU (Canada) Exploration Company Limited"

A joint venture is when two or more companies team up to work on a specific project or business idea, sharing both the risks and the rewards. It’s like friends starting a lemonade stand together—each contributes resources and they split the profits, making it easier to succeed than going alone.

toll milling financial

"currently utilizing a portion of its licensed capacity to process the ore from the Cigar Lake mine under a toll milling agreement"

Toll milling is when a company hires a third-party processor to refine, mill or transform raw materials it owns, paying a fee per unit rather than doing the work in its own facilities. For investors, it matters because toll milling can lower capital and operating costs, speed up production or preserve flexibility, but it also creates dependence on outside partners and fees that affect margins and supply reliability — like renting a specialized workshop instead of owning the factory.

About Wheeler River

Wheeler River is the largest undeveloped uranium project in the infrastructure-rich eastern portion of the Athabasca Basin region, in northern Saskatchewan. The project is host to the high-grade Phoenix and Gryphon uranium deposits, discovered by Denison in 2008 and 2014, respectively, and is a joint venture between Denison (90% and operator) and JCU (Canada) Exploration Company Limited ("JCU", 10%). In August 2023, Denison filed a technical report (the "Wheeler River Report") summarizing the results of (i) Phoenix FS; and (ii) a cost update to the 2018 Pre-Feasibility Study for conventional underground mining of the basement-hosted Gryphon uranium deposit. Based on the respective studies, both deposits have the potential to be competitive with the lowest cost uranium mining operations in the world. Permitting efforts for the planned Phoenix ISR operation commenced in 2019, culminating in the July 2025 approval of the Project's Environmental Assessment ("EA") by the Province of Saskatchewan and the February 2026 approval of the Project's EA and the grant of the construction licence by the Canadian Nuclear Safety Commission. Site preparation and early works construction commenced for Phoenix in March 2026 with first production targeted for 2028. More information is available in the technical report titled "NI 43-101 Technical Report on the Wheeler River Project Athabasca Basin, Saskatchewan, Canada" dated August 8, 2023 with an effective date of June 23, 2023, and an update to estimated Phoenix initial capital costs disclosed by press release dated January 2, 2026, copies of which are available on Denison's website and under its profile on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov/edgar.
