Western Uranium advances the Mustang mill license for the first new conventional uranium mill in the US in 40 years, targeting the supply bottleneck in domestic nuclear fuel.
Western Uranium & Vanadium said it is making progress on the radioactive materials license application for its Mustang Mineral Processing Plant in Colorado. The facility, located at the former Pinon Ridge Mill site in Montrose County, is designed to become the first new conventional uranium mill built in the United States in more than 40 years.
The company is working with eight specialized consultants and sub-consultants to prepare the application for the Colorado Department of Public Health and Environment. It is also pursuing a Special Use Permit from Montrose County. To cut costs and speed the process, Western is using digital versions of the previously licensed Pinon Ridge Mill application, the company said.
The push reflects a structural gap in the U.S. uranium supply chain. Billions of dollars have gone into downstream enrichment and conversion capacity. Front-end mining and milling capacity has not kept pace. The U.S. has not permitted a new conventional uranium mill since the 1980s. The domestic supply gap is a focus of commodities analysis at AlphaScala.
Western's Sunday Mine Complex, in the Uravan Mineral Belt of Colorado and Utah, already produces high-grade uranium and vanadium ore. The Mustang mill would give the company a local processing hub for that ore and for material from other regional deposits. The company said the region holds tens of millions of pounds of historic uranium resources that could be unlocked with modern milling capacity.
The plant is designed as a high-margin operation using kinetic separation. It will handle both uranium and vanadium recovery. Western also holds conventional projects in Colorado and Utah beyond the Sunday Mine Complex.
The mill application is one of the few tangible steps toward new domestic milling capacity at a time when utilities are restarting reactors and extending licenses. The U.S. government has promoted domestic fuel production through initiatives like the Nuclear Fuel Security Act. Western said the timing is ideal for the first new conventional mill in decades.
The company did not provide a timeline for the license submission or the county permit. CDPHE reviews typically take 12 to 18 months after a complete application is filed. The Special Use Permit process adds another regulatory layer.
The Sunday Mine Complex continues to ramp up output. Western has been stockpiling ore in anticipation of the mill's eventual commissioning. The company's strategy is to control both mining and milling, capturing margins across the domestic supply chain.
