The Rosita CPP is designed to process uranium feed from multiple satellite operations, all located in the South Texas area, and is one of eleven licensed uranium processing plants in the United States.
Satellite operations include the Rosita Project Extension, Rosita South, Butler Ranch Project and Upper Spring Creek Projects.
Rosita Property has licensed and permitted processing facilities and production areas.
Initial production of uranium utilizing the ISR process commenced in 1990 and continued until July 1999. Production was halted in July of 1999 due to depressed uranium prices. Rosita CPP restarted production in November 2023. |

Summary:
Uranium mineralization at the Rosita project occurs as roll-front-type deposits hosted in porous and permeable sandstones of the Goliad Formation (of Pliocene age), at depths ranging from 125 to 350 feet below the surface. The sandstones of the Goliad Formation occur in a deltaic to marginal marine environment of the Texas Gulf Coastal Plain which dip gently easterly into the Gulf of Mexico. Rosita’s classic C-shaped roll-front deposits comprise highly sinuous mineralized zones occurring at the interface of oxidized and reduced sediments located in the easterly part of the Rosita Property shown on the map below.
Additional potential for roll-front mineralization exists between 500 and 700 feet in the Oakville Formation and is the subject of current exploration efforts.
Summary:
The Rosita CPP receives uranium loaded resins from various remote South Texas projects and satellite wellfields. Satellite operations include the Rosita Project Extension, Rosita South, Butler Ranch Project and Upper Spring Creek Projects.
It is anticipated that production from the centrally located Rosita CPP would be primarily sourced from multiple satellite operations. There are an estimated 47 deposits with approximately 60 million pounds U3O8 of unmined in-situ amenable mineralization within the South Texas Uranium Belt.
The Company focuses on the in-situ recovery(ISR) mining method for production at its properties. The studies completed to date indicate that ground conditions and the mineral resources estimated to be contained on the Company’s Rosita, DeweyBurdock, Gas Hills, and Crownpoint-Hosta Butte ISR uranium projects, and the Project are amenable to extraction by way of ISR.
ISR uses injection wells which add oxygen and carbon dioxide creating a lixiviant solution; uranium dissolves into the solution. Recovery wells pump the solution back to the surface to a processing facility. Environmental impact manageable - no tailings, minimal dust and less water consumption than conventional mining.
