Yttrium recoveries as high as 94% as tested by independent lab
Mineralogy suggests possible, simple sulfuric acid leaching process

Texas Rare Earth Resources Corp. (OTCQX:TRER) (“Texas Rare Earth”), a heavy rare earths exploration company, is pleased to announce that testing done at Hazen Research Inc of Golden, Colorado has identified Yttrofluorite as the primary Rare Earth Element (REE) bearing mineral in samples provided by TRER from the Round Top Deposit. More significantly, this mineral also carries the majority of the high commercial value Heavy Rare Earth Elements (HREE). Yttrofluorite, due to its relative ease of dissolution in sulfuric acid as demonstrated in laboratory tests at Hazen, offers a distinct economic advantage over other less reactive HREE minerals.

QEMSCAN analysis at Hazen Research Inc has tentatively identified the primary REE bearing minerals in the Round Top deposit as Yttrofluorite (0.06 wt%), Bastnäsite (0.01 wt%), Xenotime (<0.01 wt%), and Monazite (<0.01 wt%).

Dan Gorski, CEO, stated: “One of the most important factors that determines the production costs of a rare earth deposit is the mineral that contains the REE and its ease of processing. We are pleased to have preliminary confirmation that the HREE mineral present at our Round Top project is likely amenable to simple processing. The potential of higher recovery rates than as cited in our June 2012 Preliminary Economic Assessment (PEA) bodes well for future capital costs and hence potential economic viability of our Round Top project.”

Preliminary leach tests that have been run on whole ore samples at Hazen have yielded yttrium recoveries as high as 94% at 90-95°C at a sulfuric acid strength of 100 gm/liter (approximately 10%). Recoveries of other REEs are pending analysis being done at Actlabs in Canada and results will be disclosed shortly. Work continues on optimizing the leach parameters and on pre-concentration by flotation and/or magnetic separation. The potential for heap leaching the Round Top Deposit is also being considered.

We estimate that Yttrium comprises approximately 41% of our REE mix by weight. 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.
