Ur-Energy Ships First Uranium from Shirley Basin Mine to Lost Creek Processing Plant

U.S. uranium producer Ur-Energy announced that on August 19, 2026, its Shirley Basin uranium mine in Wyoming shipped its first uranium to the Lost Creek processing plant in the same state. This marks the company's second in-situ recovery (ISR) uranium mine entering full production and beginning its ramp-up phase.

Ur-Energy President and CEO Matt Gili stated that the shipment of first uranium signifies the full commissioning of the Shirley Basin project and represents the company's transition into a multi-asset U.S.-based uranium producer. According to him, the Shirley Basin project took approximately two and a half years from planning and construction to production.

The Shirley Basin uranium mine is Ur-Energy's second in-situ recovery uranium mining project in Wyoming, with wellfield and toll processing capacity of up to 2 million pounds U₃O₈ equivalent. The mine initiated initial mining operations in April 2026 and received final approval for full production from the Wyoming Department of Environmental Quality in late June 2026.

Under the company's plan, the Shirley Basin mine operates as a satellite mine to the Lost Creek hub. Lost Creek is an operating in-situ recovery uranium mine whose facilities have previously processed and delivered over 3.5 million pounds of triuranium octoxide (U₃O₈) to conversion facilities for customer delivery.

Ur-Energy stated that with transportation from Shirley Basin to Lost Creek now underway, the company will continue to ramp the project to full commercial operation as planned and advance its other growth projects in the region. The company currently operates two ISR uranium mines, Lost Creek and Shirley Basin, with a combined annual licensed production and toll processing capacity of 4.2 million pounds U₃O₈.
