Texas Rare Earth Resources Further Defines Heavy Rare Earth Mineralogy and Initial Leaching Characteristics of Round Top Deposit
April 16, 2013 (Source: WSJ) Sierra Blanca, TX — Texas Rare Earth Resources Corp. (OTCQX: TRER) (“Texas Rare Earth”), an exploration company developing its Round Top property whose rare earth content is approximately 70% heavy rare earth elements* is pleased to announce highly encouraging results of acid bake extraction of whole ore samples from the Round Top deposit with testing done at Hazen Research Inc of Golden, Colorado and analysis from Act Labs in Canada.

The testing by Hazen Research, was on ground whole rock treated with concentrated sulfuric acid and baked for one hour at 325 degrees C followed by a water leach. Analysis was done at Actlabs Ltd., in Canada.
These data confirm that it is possible to obtain high recoveries of all the REE’s during this crucial “first step” of the separation process. Of particular importance is the high recoveries of Dysprosium (Dy), Yttrium (Y) and Neodymium (Nd) which are considered to be “critical” rare earth elements.
Additional work continues on optimizing the leach parameters and on improving flotation recoveries. The potential for heap leaching the Round Top Deposit is also being independently tested. Dan Gorski, CEO, stated: “These results are encouraging and serve to support the earlier findings disclosed in our press release of March 20, 2013, that the REE bearing minerals, principally Yttrofluorite, are soluble in sulfuric acid. We are pleased with the high recoveries of the three “critical” rare earth’s, (Dy, Y and Nd) which aggregate approximately 42% of the contained rare earth elements at Round Top. ”
These results are preliminary in nature and more research needs to be done. Acid consumption and process development designs must be determined before an economic process can be defined and a determination of potential preliminary economic viability of the process can be made. The Round Top project does not contain proven and probable reserves under the Securities and Exchange Commission’s Industry Guide 7 and our activities are exploratory in nature.
