SnapshotThe 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.

Deposit type

  • Sandstone hosted

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.
