Rook I Project

Small Footprint, Big Impact

The world’s leading uranium development project located in Canada's southwestern Athabasca Basin, Saskatchewan.

Production Shaft

Smart, Safe, Innovative

State of the art facilities and infrastructure are being developed with automation and safety at the forefront. The underground mine is serviced by two vertical shafts. The Production Shaft will transport personnel, materials, and rock while providing fresh air to the underground workings.

Shaft Access

Accessing the Underground

The headframe and production shaft are used to safely bring equipment, material, and people in and out of the mine at a depth of 630 metres. Over 7,000 tonnes per day of rock will be hoisted to the surface.

Arrow Deposit

Flexible, Reliable, & Environmentally Elite

With a measured, indicated and inferred resource of 337.4 million lbs, (3.10% grade for M&I) and open in all directions while being hosted completely in basement rock.

Mining Method

Proven Techniques, Innovative Tailings Approach

The Mining method utilises conventional long hole stoping to extract the ore. Active reclamation during production through utilising paste tailings and the innovate Underground Tailings Management Facility (UGTMF) will eliminate surface tailings and mitigate end of life liabilities.

Underground Access & Equipment

Utilizing Technology

Using a fleet of automated and tele-remote equipment, uranium ore will be extracted from stopes and transported through a material handling system where it will eventually be hoisted to surface.
Ore will stockpiled and blended to provide consistent feed to the Mill and maximize uranium recoveries.

ROOK I Highlights

The Largest Source Of Low-Cost Uranium Globally

Current Development Stage

The company is now progressing through advanced stages of engineering, having started on critical path activities, which include procurement of long lead equipment and critical path contracts. Shaft Sinking of the Production and Exhaust Shafts are the first major activities that will begin on site.

Project Infrastructure

The Rook I Project will consist of an underground mine and mill utilizing conventional methods. Innovative infrastructure such as the Underground Tailings Management Facility (UGTMF) will deploy proven technology to eliminate surface tailings and mitigate end of life liabilities.

Feasibility Study

The current design outlines an initial mine life of 11.7 years, with a 24-year permit, capable of producing an average of up to 29.2 Mlbs U3O8 annually for the first 5 years, making it the largest and lowest cost uranium mine in the world.
