Anfield said the advanced project was a key part of its plan to create a "robust mine and mill production complex in Wyoming" and pointed out it had a resin processing agreement in place with Uranium One to produce up to 500,000 pounds of uranium per year at its nearby Irigaray processing plant.
Anfield has acquired Charlie from the General Atomics-affiliated Cotter Corporation, which will take a 10% stake in Anfield and retain a 20% interest in all yellowcake production from the project.
Anfield will gain previous exploration data and plans to rapidly prepare technical reports on the project, which has an historic feasibility study based on 1,252 drill holes.
"We are excited to add the Charlie project to our portfolio of uranium properties," Anfield CEO Corey Dias said.
"We are now well-positioned for production when market conditions are right.
"Moreover, in building a significant resource pipeline we are continuing to update and delineate uranium resources at the 24 Wyoming uranium projects acquired from Uranium One in 2016."
Anfield also owns one of three licensed uranium mills in the US, the Shootaring Canyon Mill in Utah.
The company changed its name from Anfield Resources to Anfield Energy in December to reflect its energy metals portfolio of uranium and vanadium, and consolidated its shares on a 10:1 basis.
Its shares rose 15.12% yesterday to C49.5c, representing a year-to-date gain of more than 41% and capitalising it at $11.1 million.
