Texas Rare Earth Resources Corp. Announces Lease on Heavy Rare Earth Deposit at Round Top Mountain

TYLER, Texas, October 6, 2010 - Texas Rare Earth Resources Corp. (Pink Sheets: SDSR), formerly Standard
Silver Corporation, announced today it has executed a 20 year lease ("Lease")
with the Texas General Land Office covering 860 acres at Round Top Mountain
in Hudspeth County, Texas ("Round Top"). Additionally, Texas Rare Earth owns
prospecting permits for approximately 10,000 acres adjacent to the Lease. We
believe the favorable mineralogy and the 67% heavy to light rare earth ratios
in samples from the deposit may offer attractive targets ranging from a one
billion ton plus bulk low grade mineable deposit hosted in the Round Top
rhyolite intrusive, to more conventional higher grade targets hosted deeper
in the intrusive and in the carbonate wall rocks. Should processing of this
rhyolite prove feasible, we believe Round Top has the potential to become a
long term domestic source of these strategically vital metals.

Management plans to pursue several alternatives for developing the rare
earth (REE) potential of Round Top. Round Top was the site of extensive
drilling in the 1980's by Cabot Corporation and Cyprus Minerals. Based on
published sets of samples (Price et al 1990 GSA Special Paper 246), as well
as internal sampling now in progress, we believe that the in place value per
metric ton of the rhyolite is sufficient to warrant examining the possibility
of developing a large scale open-pit mining operation if a process can be
developed to concentrate the rare earth minerals. The mass of the Round Top
rhyolite body has been estimated by Texas Bureau of Economic Geology
geologists to be at least 1.6 billion metric tons. The heavy to light rare
earth ratio of 67% seen to date is highly encouraging. There also exists a
possibility that other minerals containing other rare elements such as
niobium, tantalum, zirconium, hafnium and lithium may be co-produced.

There may exist enriched phases within the Rhyolite. The samples analyzed
to date are predominantly from the border zone of the rhyolite body.
Preliminary examination of drill samples indicates a wide variation of
grain-size and alteration style within the rhyolite. We believe that there is
the possibility that phases of this rhyolite will be enriched in REE and
other rare elements and that this concentration and stratification of the REE
in the cooling igneous rock may be analogous to the geology in Avalon's Thor
Lake deposit.

High grade replacement deposits in the underlying limestones and veins or
pegmatites within the rhyolite may exist. Unlike most REE deposits now being
explored, the Round Top mineralizing system has not been deeply eroded and
only its upper parts are exposed. A striking feature of this deposit is the
intensity of hydrothermal alteration and brecciation associated with it and
the high fluorine content of the rhyolites, 1.3% for the Round Top rhyolite.
These rhyolites have intruded thick sections of carbonate rocks. Carbonate
rocks are extremely reactive and are readily replaced by fluorite when
contacted by solutions high in fluorine. Fluorine is the active agent that
mobilizes the REE, beryllium and uranium and other metals in these types of
geologic systems. REE's are significantly less soluble than beryllium or
uranium and can be expected to be the first elements deposited deeper in the
system and would be expected to form replacements in the first limestones
they come in contact with.

We are currently evaluating data from the Cabot Corp-Cyprus Minerals
beryllium exploration and development program in the late 1980's for rare
earths and uranium. Samples from approximately 200 reverse circulation and
core drill holes aggregating approximately 45,000 feet have been sorted and
securely stored. Equipment and facilities have been established for detailed
re-logging. To date, some 44 of these drill holes have been re-logged.
Selected samples are being submitted for chemical analysis. In addition to
REE, we believe the property may contain commercial quantities of beryllium
and uranium.

To more accurately reflect its focus on the development of the heavy
earth Round Top deposit, the company has changed its name to Texas Rare Earth
Resources Corp.
