Texas Rare Earth Resources Leaches Significant Beryllium and Lithium From Round Top Rhyolite

  • Recoveries of Beryllium and Lithium From Whole Rock Leaching at Room Temperature Suggest Extra Potential Revenue Streams From Round Top Project

SIERRA BLANCA, Texas, May 8, 2013 (GLOBE NEWSWIRE) -- Texas Rare Earth Resources Corp. (OTCQX:TRER) ("Texas Rare Earth"), a heavy rare earths exploration company, is pleased to announce the recovery of beryllium and lithium in leach solutions of Round Top rhyolite. It was previously thought that potentially economically important beryllium mineralization was limited to the contact zone at the base of the rhyolite, where a definitive feasibility study for a beryllium mine was done by Cyprus Minerals in the 1980's. A portion of the trace amounts of these elements that pervade the bulk rock now appear to be potentially recoverable by heap leach.

Whole rock leaching of sieved 2 to 4 mm (~1/8th to 1/4 inch) rhyolite particles tested at Mountain States R&D International of Vail, Arizona at room temperature in 14.7 gm/l (14.7% by wt) sulfuric acid for two weeks yielded potentially economically significant amounts of beryllium and lithium. Initial test results are summarized below:

Be Li
ppm ppm
Ore Sample 32.2 410
Recovery 1 6.50 270
Residue Split 2 4.80 270
Residue Avg. 5.65 270
% Recovery 18% 66%

The results from Mountain States and analysis by ALS Ltd of Canada suggest that an operation mining and processing 14,500 tonnes per day could recover into solution annually approximately 22 tonnes of beryllium metal and 1,340 tonnes of lithium metal or approximately 62 tonnes of beryllium oxide and 7,173 tonnes of lithium carbonate, respectively. The potential economic significance of the presence of these non-rare earth elements in the leaching solution is the fact that once dissolved, they must be removed either to be disposed of as waste or to be sold as a commodity. Stripping metals from solution is typically by a well-established process.

Beryllium is used in high-tech alloys, ceramics and electronics; lithium is a crucial component of the Li-ion batteries that power many portable electronic devices including electric vehicles. Prices for these commodities are believed to be high enough to warrant further work on economic possibilities of these metals.

Dan Gorski, CEO, commented, "We regard the results thus far obtained on recovery of beryllium and lithium as a material development. TRER is fortunate to have a deposit where a variety of elements such as uranium, thorium, beryllium, lithium, manganese, zinc and rubidium report to the sulfuric acid leach solutions. We plan to aggressively pursue the possibility to produce a marketable product of all these elements. Adding a diversified revenue stream from these by-products would potentially both increase the profitability and decrease the risk of the mine."
