Uranium Energy Corp Announces Results of Metallurgical Testing at Its Goliad Uranium Project
May 3, 2007
Extraction Efficiency of 86% To 89% Uranium from Goliad Ore Indicates Favorable Amenability to ISR Mining
AUSTIN, TX – May 3, 2007 – Uranium Energy Corp announces results of Recovery Amenability and Oxidant Requirement Tests that were conducted by Energy Laboratories Inc. of Casper, Wyoming. The tests were conducted on uranium core samples recovered by Uranium Energy Corp during its 2006/07 drill program at the Goliad Uranium Project in South Texas. These metallurgical test results indicate that Goliad Project mineralized material is amenable to a high degree of uranium recovery.
Recovery Amenability studies demonstrate that a uranium ore can be leached by using conventional in-situ recovery (ISR) chemistry. The tests do not approximate in-situ conditions (permeability, porosity, and pressure) but provide an indication of an ore’s reaction rate and the potential uranium recovery.
The results of the 4 bottle roll leach tests indicate that the recovery efficiencies for the Goliad Project’s “A” Sand were in the range of 86 to 89%. The ore is easily dissolved and the extraction efficiency is only slightly dependent on the amount of oxygen used during the leaching process. Of 4 tests conducted, 2 were conducted with a "standard strength oxidizer" or 0.5 g/L H2O2, while the other 2 tests were conducted with ½ the "standard strength oxidizer" or 0.25 g/L H2O2. Results of the four leach tests are summarized below:

Test Conditions
Company geologists selected 4 core interval samples for sequential leach amenability and oxidant requirement studies. The first 2 intervals represented relatively high grade ore, in the range of 0.08% uranium, and the second pair of samples represented lower grade ores. Ore grade on the splits used for the leach test was chemically verified on a whole ore basis.
Split sections of one foot of core were placed in 2-liter, wide-mouth plastic containers and a lixiviate comprised of 2.0 g/L HCO3 (NaHCO3) and either 0.50 g/L H2O2 or 0.25 g/L H2O2 was added at a 5 pore-volume (5PV) liquid-to-solid ratio. One pore-volume of the selected core samples should, at roughly 30% porosity, equal 100ml. Five hundred milliliters of the lixiviate was added to the 333 cm3 core samples and the reaction vessel was rotated on a TCLP extractor for 16 hours at 30 RPM.
This step was repeated 5 more times with fresh lixiviant representing a total of 30 pore volumes of contact. Uranium recoveries ranged from 86.4% to 88.9% indicating favorable amenability to ISR processing.
