Deep Yellow (ASX:DYL) has released the results of the Tumas Definitive Feasibility Study (DFS), showing the flagship uranium project as a potential world-class operation, delivering "robust returns to shareholders".

Deep Yellow says the Namibia-based uranium project will treat 4.15Mt per year to produce up to 3.6 Mlb uranium per year, and 1.15 Mlb vanadium by-product.

It also says the project's Life of Mine (LOM) is 22.25 years based on existing ore reserves, with additional resources likely to increase its life to a +30-year operation.

Deep Yellow's CEO and MD, John Borshoff says the DFS is the most significant event in the company's history, and intends for it to be a best in-breed uranium operation with world-leading extractive technologies and sustainability initiatives applied.
