The project uses in-situ recovery, a solution mining method where oxygenated water is injected underground to dissolve uranium. The uranium-bearing solution is then pumped to a central processing plant. The plant has a total operating capacity of 1.5 million pounds of U3O8 per year and an additional drying capacity of 0.5 million pounds. In March 2025, the company started a second ion exchange circuit, doubling the total flow capacity. A third circuit is planned for recommissioning in 2026, which will bring the plant to its full ion exchange capacity.

enCore Energy is actively expanding wellfields to increase production. The company is increasing production from Production Authorization Area 7 (PAA-7) and has started work on a second new wellfield at Production Authorization Area 8 (PAA-8), with the goal of reaching full operational capacity by 2026. Initial work has also begun at the permitted Wellfield 6, with a planned resumption of operations in the fourth quarter of 2025. In August 2025, enCore acquired the 5,900-acre "Tacubaya" property adjacent to the existing wellfields, which is expected to provide additional feed and extend the project's life. An exploration program on this new property is planned. In October 2025, the company announced new uranium discoveries near existing wellfields resulting from a re-analysis of historical drill holes. Delineation drilling of these new roll fronts is expected to continue into 2026.
