Anfield Energy’s Utah uranium mill approvals: design and licensing notes for engineers
Reviewed by Tom Sullivan

30 Second Briefing
Anfield Energy has received draft renewal documents for the radioactive materials licence and groundwater discharge permit for its Shootaring Canyon Mill in Garfield County, Utah, one of only three constructed conventional uranium mills in the US. The draft licence would cap production at 1,500 tonnes, or 3 million lb, of yellowcake per year and mandates a financial surety, a defined groundwater monitoring network, and best available technology standards for process ponds, the South Cell and decontamination pad. Anfield is stripping legacy mill equipment ahead of targeted licence renewal in Q2 2027, while its Velvet-Wood project holds 4.6 million lb eU3O8 measured and indicated plus 552,000 lb inferred.
Technical Brief
- Draft radioactive materials licence explicitly authorises possession of natural uranium and 11e.(2) byproduct material onsite.
- Compliance framework includes defined groundwater monitoring network plus associated compliance monitoring and reporting obligations.
- Best available technology standards are mandated specifically for process ponds, the South Cell and the decontamination pad.
- Legacy mill equipment removal is occurring under the existing licence, maintaining regulatory control during pre-refurbishment works.
- Public notice and comment is planned around end‑2026, with a 45‑day formal comment window.
Our Take
The 3-million-lb/y yellowcake capacity in the draft licence is materially larger than the 4.6 million lb eU3O8 measured and indicated resource at Velvet-Wood, implying Anfield will likely need additional feed sources or toll-milling arrangements to utilise the mill fully.
