Searchlight Minerals Corp. provides metallurgical testing results and project updates

    HENDERSON, NV, Aug. 20 /CNW/ - Searchlight Minerals Corp. (OTC BB: SRCH)
(the "Company"), today announced that it has received metallurgical testing
results conducted by its independent mining consultants, Arrakis, Inc
("Arrakis"), on chain-of-custody samples collected from the Company's
Searchlight Gold Project in southern Nevada. Also, the Company is providing a
status report on its Clarkdale Slag Project.

    Searchlight Gold Project

    The Company has received a report from Arrakis outlining the results and
analysis of the metallurgical testing it has completed on behalf of the
Company over the past six months. Following the results reported by the
Company on January 29, 2007, indicating a significant presence of gold based
on surface sampling, the Company engaged Arrakis to perform additional
metallurgical testing on chain-of-custody samples taken from the Company's
3200 acre project site near Searchlight, Nevada. In particular, the Company
was looking to identify a repeatable analytical protocol for precious metal
content in small samples and a commercial-scale protocol appropriate for large
bulk samples that could be scaled to mine-sized production.
    Results from Arrakis indicate that although the material on the project
site appears to be refractory, "microwave digestion" has provided consistent
results on small size samples, indicating that this would be a reliable
analytical protocol. On large bulk samples, "autoclave" technology appears to
be the most consistent and reliable extraction protocol to leach gold into
solution and could be scaled to commercial-sized production. Optimizing the
recovery of gold from solution in the autoclave process, however, has yet to
be completed. While other analytical and extraction methods were evaluated,
they did not appear to be as consistent and reliable as the aforementioned
metallurgical protocols.
    "Initial and subsequent surface sampling of the Searchlight property have
consistently revealed in-situ grades of 0.3 to 0.4 opt (ounces per ton) over a
very wide surface area," observed James Murray, President of Arrakis, Inc.
"While these are surface samples only and therefore cannot be used to
extrapolate the depth or areal extent of the resource, it would be a very
unusual deposit that did not also have significant mineralization at depth."
    "We are very pleased with the advancements made on the metallurgical
program at our Searchlight Gold Project," stated Ian McNeil, Chief Executive
Officer and President of Searchlight Minerals Corp. "While metallurgical
optimization testing will continue, we believe our progress is sufficient to
begin an 18-hole drilling program this fall. This drilling program will be the
next major milestone in analyzing the project's feasibility."

    Clarkdale Slag Project

    As previously reported by the Company on May 22, 2007, tonnage and grade
estimates of the slag pile were reported as approximately 20 million tons of
slag and 0.50 opt gold, 0.10 opt silver, 0.34% copper, 2.46% zinc and 33.15%
    Over the past six months, significant progress has been made on the
development of the Clarkdale Slag Project. In particular, advancements in the
building construction and the site remediation program are continuing without
interruption. The Company has also hired a number of employees, including a
full-time Operations Manager with over 25 years of mining industry experience.
Also, many of the purchase orders have been issued for the processing
equipment to be utilized in the first module of production.
    "Progress at the Clarkdale Slag Project continues at a pace consistent
with management's expectations. We have an incredibly skillful team of
employees, consultants and contractors working on our Clarkdale Project"
reported Mr. McNeil. "We look to continue the forward momentum on the project
including completion of the building construction, implementation of the
processing equipment and ultimately the feasibility of the first module of
