Texas Production Facilities

Kingsville Dome

Project Highlights

Licensed ISR production facility with 800,000 pounds of U3O8 per year capacity
Designed to process feed from multiple satellite operations
Previous production of 4.2 million pounds of U3O8 from ISR methods
Located within the South Texas Uranium Belt, which hosts an estimated ~60 million pounds of unmined U3O8

Project Details


The Kingsville Dome Central Processing Facility (“CPP”) is located in Kleberg County approximately 35 miles southwest of the city of Corpus Christi, Texas.

Access to the Kingsville Dome process facility is very good with an improved company-owned private road that connects with Texas Farm to Market Road 1118 about eight miles southeast of Kingsville and about four miles east of U.S. Highway 77. Electrical power is readily available with an industrial-scale power line extending to the Kingsville Dome CPP.

The project is comprised of numerous mineral leases from private landowners, covering an area of approximately 2,227 acres of mineral rights.


The Texas Commission on Environmental Quality (“TCEQ”) regulates uranium mining and issues the necessary license and permits.  A Radioactive Material License issued by TCEQ covers the Rosita, Kingsville Dome and Vasquez projects and it is in timely renewal. Each site also has class I non-hazardous injection permits for operation of waste disposal wells on site, which are regulated by the TCEQ as well. All permits for the disposal wells are active.  

Production History

The Kingsville Dome CPP was constructed in 1987 and has operated intermittently from 1988 to 2009, at which point it was placed on standby. Approximately 4.2 million pounds of U3O8 has been produced from the project area. The majority of historic production was sourced from the Kingsville Dome uranium deposit.

The facility consists of an up-flow uranium extraction circuit, with complete drying and packaging facilities within the recovery plant. Two independent resin processing circuits and elution systems are part of the plant’s processing equipment, and it also has a single drying circuit.

The plant can serve as a central Ion Exchange (IX) facility that can process resin loaded with uranium from multiple satellite facilities. In addition to the processing plant there are four satellite IX systems in the project area.  As currently configured, the Kingsville Dome plant has a licensed production capacity of 800,000 pounds U3O8 per year.

Geology and Mineralization

Uranium mineralization at the Kingsville Dome project occurs as roll-front deposits hosted in porous and permeable sandstones of the Goliad Formation, at depths ranging from 600 to 750 feet beneath the surface. The mineralization is localized along the southwestern to northern flanks of the Kingsville Dome geological feature, which also hosts oil and gas deposits in geological units that are situated well below the Goliad Formation sandstones.

At present, there are no significant estimated uranium resources at the Kingsville Dome project.Douglas H.
