Snapshot	Palangana is advancing the fully permitted, past-producing project for production re-start. Palangana produced 563,600 lbs U3O8 from 2010 to 2016 and currently has the infrastructure to begin mining immediately. Uranium Energy has completed all the required permitting in order to mine at Palangana. It has been carried in a care and maintenance condition since cessation of uranium recovery in 2016. During Fiscal 2023, Uranium Energy continued with the strategic plan for reduced operations at Palangana Mine. As a result, no uranium concentrate was extracted at Companies ISR Mines and processed at the Hobson and the Irigaray Processing Facilities during Fiscal 2023 and Fiscal 2022. For Fiscal 2024, uranium extraction at PAA-1, 2 and 3 of Palangana Mine is expected to continue being operated at a reduced pace, including the deferral of major pre-extraction expenditures, and to remain in a state of operational readiness in anticipation of a sustained recovery of uranium prices.

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.
