Texas Rare Earth Resources Reports Significant Heavy and Critical Rare Earth Recoveries in Column Leach Testing by Independent Laboratory
Lab Results Point to Enhanced Potential for Bulk Mining and Treatment of Resources
SIERRA BLANCA, Texas September 30, 2013 (MARKETWIRE) -- Texas Rare Earth Resources Corp. (TRER), a heavy rare earths exploration company, today announced results from independent column leach tests conducted by Resource Development Inc (RDI) of Wheat Ridge, Colorado.
Preliminary Column leach testing of Round Top rhyolite crushed to 1/2 inch has yielded the following recoveries of the heavy rare earth elements (terbium and heavier) plus yttrium. These tests were run for 60 days with 7.5 wt. percent sulfuric acid. Recoveries of the heavy rare earth elements plus Yttrium were as follows:
Yttrium (Y): 91%
Dysprosium (Dy): 87%
Lutetium (Lu): 67%
Holmium (Ho): 86%
Erbium (Er): 83%
Thulium (Tm): 77%
Ytterbium (Yb): 74%
Terbium (Tb): 87%
While concurrent work on the froth floatation and agitated leaching of the concentrates yielded acceptable recoveries, the whole rock column leach testing indicates better overall recoveries at potentially lower capital and operating costs. This rock also shows other very favorable heap leach characteristics with ore slump of 0.18%, ore wt. loss of 2.25% and retained moisture of 6.4%.
Work will continue to optimize the recoveries of the heavy rare earth elements (HREE) and yttrium as well as potentially valuable by-products such as uranium, beryllium and lithium and the light rare earth elements (LREE).
Dan Gorski, CEO states: "We are highly encouraged by these results and plan to issue a revised preliminary economic analysis (PEA) based on a heap leach operation designed to produce approximately 2,500 tons per year of HREE plus yttrium. We are confident that the high recoveries seen so far and the typically low capital and operating costs associated with large scale heap leaching, combined with zero stripping ratios and near ideal climate and topography can make Round Top a significant low cost and long term supplier of these strategic elements."

This press release contains forward-looking statements within the meaning of the U.S. Securities Act of 1933, as amended, and U.S. Securities Exchange Act of 1934, as amended, including, but not limited to, statements regarding the potential better overall recoveries and capital and operating costs from a heap leach mine compared to froth floatation and agitated leaching, continuing work to to optimize the recoveries of the heavy rare earth elements and yttrium as well as potentially valuable by-products such as uranium, beryllium and lithium and the light rare earth elements, timing and results of the revised preliminary economic asessment, potential factors that could make Round Top a significant low cost and long term supplier of heavy rare earth elements and yttrium and other such similar statements. When used in this press release, the words “potential,” “indicate,” “expect,” “intend,” “hopes,” “believe,” “may,” “will,” “if, “anticipate,” and similar expressions are intended to identify forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by such statements. Such factors include, among others, risks related to changes in future operating costs and working capital balance, risks related to mineral estimates, risks related to mining results not matching preliminary tests and risks related to the ability of the company to successfully monetize its non-rare earth resources, as well as those factors discussed under the heading “Risk Factors” in the Company’s latest annual report on Form 10-K, as filed on November 15, 2012, and other documents filed with the U.S. Securities and Exchange Commission.
