The Christie Lake project is an advanced-stage exploration project located approximately 9 kilometres northeast of the McArthur River uranium mine. The project hosts several high-grade uranium deposits, including Paul Bay, Ken Pen, and Ōrora. The vertical depth to the unconformity-hosted mineralisation at Christie Lake is between 400 and 420 metres from the surface. An updated resource estimate for the project is anticipated in 2023.

In 2022, a new high-grade discovery was made, named the Sakura Zone. Subsequent drilling in early 2023 expanded the footprint of this new zone.

The plan is for processing to occur at the McClean Lake mill, in which Denison holds a 22.5% ownership interest.

The deposit was formerly known as the J Zone. In 2020, a Preliminary Economic Assessment (PEA) was completed to evaluate the use of the In-Situ Recovery (ISR) mining method. Throughout 2023 and 2024, Denison continued evaluation work, including metallurgical testing and an ISR field program, to support a future Pre-Feasibility Study (PFS). A 2023 field test program confirmed that the deposit is amenable to ISR mining.

The Midwest A deposit is a component of the Midwest Project, which also includes the Midwest Main deposit. The project is situated in the eastern Athabasca Basin of northern Saskatchewan, approximately 25 kilometres from the McClean Lake mill, which is partly owned by Denison and is where ore from the Midwest project is expected to be processed.

A Preliminary Economic Assessment (PEA) completed in August 2025 outlines a total potential production of 37.4 million pounds of U3O8 over the life of the mine. The potential annual average production is nearly 6.1 million pounds of U3O8. The PEA assumes that uranium-bearing solution recovered from the mine will be processed at the nearby McClean Lake mill.
