Searchlight Minerals Corp. provides metallurgical testing results and project updates

Aug 20, 2007, 01:00 ET from Searchlight Minerals Corp.

    HENDERSON, NV, Aug. 20 /PRNewswire-FirstCall/ - 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
     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
     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
     "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
     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% iron.
     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 production."
