The AI Nuclear Acceleration: Why Big Tech is Fueling a U.S. Uranium Gold Rush
Grid Power Milestone and SABRE Production Offset 20% Capital Cost Hike as Phoenix Nears Final Investment Decision

The most recent release (Jan 14, 2026) is a sponsored commentary highlighting a "U.S. Uranium Gold Rush" fueled by AI energy demands. For Denison Mines, it recaps a critical infrastructure milestone: grid power from SaskPower is now available at the Phoenix mine site. This follows the Jan 8, 2026, announcement of the completion of a 138kV transmission line. Earlier in the month (Jan 2, 2026), the company declared readiness for a Final Investment Decision (FID) on its flagship Phoenix ISR project, despite a 20% increase in initial capital costs to CAD $600 million.
The news of grid power availability is a material de-risking event. By shifting from on-site power generation to the provincial grid, the company secures more reliable and cost-effective energy for construction and operations, which is critical for the "first-on-the-continent" ISR uranium project.
However, the 20% capital cost increase (from $419M to $600M) reported on Jan 2 is a significant hurdle. While the project's economics remain robust due to high grades (Post-tax IRR of 73% at $68-78/lb U3O8), the cost inflation reflects broader industry pressures. The immediate material impact is positive due to the successful transition to production status at McClean North via the SABRE method, which provides proof of concept for the company's unconventional mining expertise.
Denison Mines is a leading uranium developer focused on the Athabasca Basin in Saskatchewan. Its flagship project is the Wheeler River Project, which hosts the Phoenix (high-grade ISR) and Gryphon (underground) deposits. Phoenix is designed to be the first In-Situ Recovery (ISR) uranium mine in Canada, targeting a low-cost profile with an average all-in cost of approximately $16.04 USD/lb. The company also owns 22.5% of the McClean Lake mill and the McClean North mine, which recently restarted production using the innovative SABRE mining method.
