SnapshotThe Palangana Mine is an ISR uranium project that commenced extraction in 2010 and has been on care and maintenance since 2016. The mine remains fully permitted and in operational readiness, with any restart requiring additional capital expenditure to re-activate idled wellfields.

The Hobson Central Processing Plant (CPP) fully licensed, is the core facility of the South Texas “hub-and-spoke” strategy. Hobson acts as the central hub for Palangana and future satellite projects, including Burke Hollow, Goliad, and Salvo.

Uranium Energy Corp. 100 % Indirect
In 2005, Everest Exploration Inc. acquired the Palangana property and later joint ventured with Energy Metals Corp. through the formation of South Texas Mining Venture, L.L.P. (“STMV”). In December 2009, Uranium Energy Corp. acquired 100% ownership of STMV.

Uranium Energy Corp. holds various mining lease and surface use agreements, generally having an initial five-year term with extension provisions, granting the exclusive right to explore, develop, and mine for uranium at its Palangana Mine.

Summary:

The local geology at the Palangana Project Area is characterized by the occurrence of a Gulf Coast piercement salt dome. This dome is approximately two miles in diameter and is overlain by Pliocene sediments of the Goliad Formation. The Palangana Project Area dome is marked at the surface by a shallow circular basin surrounded by low hills rising above the basin floor. The Palangana Project Area dome has an almost perfectly circular salt core with a remarkably flat top that is approximately 10,000 feet across and occurs from 800 to 850 feet below ground surface (“bgs”). Radial faulting is present in all Goliad Formation sands on the flanks of the dome due to uplift during the intrusion of the dome. Faults and fractures also exist in a random nature in the sands above the caprock due to dissolution of the salt dome from groundwater. Once the salt was solubilized and removed, the overlying sediment collapsed, creating the basin and associated faults.

Uranium mineralization at the Palangana Project Area is typical of Texas roll-front sandstone deposits. Uranium mineralization occurs along oxidation/reduction interfaces in fluvial channel sands of the Goliad Formation. These deposits consist of multiple mineralized sand horizons, which are separated vertically by confining beds of silt, mudstone, and clay.

The Goliad Formation at the Palangana Project Area is composed of fine- to medium-grained, often silty, channel sands interbedded with lenses of mudstone and siltstone. For the most part, the sand is very sparsely cemented although it varies from friable to indurated. There is known to be minor faulting on the north end of the PA-1 deposit. The Palangana Project Area stratigraphy is horizontal to sub-horizontal, with a 2-to-3-degree southeasterly dip at most.
