SnapshotThe Rosita Uranium Operation includes the previously producing Rosita In-Situ Recovery (ISR) Uranium Central Processing Plant (CPP), the Rosita Production Area 5 (Rosita Extension wellfield or PAA-5), as well as proposed satellite project areas (the South Texas Integrated Uranium Projects).

The South Texas Integrated Uranium Projects include:
• The Upper Spring Creek – Brown Area ISR Uranium Project, scheduled for development by 2026, having received inclusion in the Radioactive Materials License (RML).
• The Upper Spring Creek – Brevard Area ISR Uranium Project, scheduled for development from basal Oakville Formation sands in late 2026, dependent upon permitting.
• The Rosita South Cadena ISR Project.
• The Butler Ranch Uranium ISR Project.

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.
