Ur-Energy Estimates Lost Creek Wastewater Costs at Up to $35 Million

Ur-Energy put the estimated cost of a permanent wastewater treatment facility at its Lost Creek operation at up to $35 million as it prepares for Mine Unit 5 production in early 2027.

The estimated capital cost is $33 million to $35 million, including a sand filtration system. Ur-Energy projects about $23 million in spending in 2026 and $11 million in 2027. It had spent $7.7 million through Sept. 30.

Wastewater capacity has limited the use of the filtration system, which removes fine particles from the wellfield and is designed to increase flow rates. The company expects the wastewater facility to begin operating in the first half of 2027.

Ur-Energy submitted the first phase of its Mine Unit 5 (MU5) regulatory package to the Wyoming Department of Environmental Quality (WDEQ) in September. The company expects approval in time to begin MU5 production in the first quarter of 2027.
