SEARCHLIGHT MINERALS CORP. ANNOUNCES
SIGNIFICANT TECHNICAL ACHIEVEMENT IN GOLD AND IRON RECOVERY AT ITS CLARKDALE SLAG PROJECT
HENDERSON, Nevada (May 9, 2014) -- Searchlight Minerals
Corp. (OTCBB: SRCH) (“Searchlight” or the “Company”) today announced significant technical achievements
in gold and iron recovery at its Clarkdale Slag Project.
These achievements include, but are not limited to:
| · | The determination of precise nature of the gold contained in the slag
material. |
| · | The addition of a high temperature pre-treatment step that aids in
the recovery of the gold and provides a saleable iron byproduct. |
| · | Up to a 60% extraction of metallic gold from fire assay of ion exchange
resin. |
Based on the achievements above, the Company believes that the
project is commercially viable, if repeatable, at current results.
Significant technical results achieved
in Gold recovery
As previously reported, the Company
has been working to demonstrate economic feasibility of its Clarkdale Slag Project by successfully operating four major steps of
the production process: crushing and grinding, leaching, continuous process operation, and extraction of gold from solution. The
current work program has focused primarily on extraction of gold from solution as the Company believes the first three steps have
shown to be successfully completed.
As noted in the Company’s recently
filed annual report (Form 10-K), in order to both increase gold recovery and improve the overall production process, the Company
has been performing tests whereby the slag material is pretreated prior to processing it in the autoclave. Recent test work indicates
that pretreatment, by melting the slag at high temperature, aids in the recovery of the gold from solution derived from the autoclave.
The Company believes that the high temperature process aids in breaking down the refractory coating on the gold particles that
are subsequently put into solution after the autoclaving of the slag material and also separates out the iron that makes up approximately
one third of the untreated slag material.
The heat treated slag material, after
the removal of the iron is, for ease of reference, hereinafter referred to as glass. This processed glass material contains
the gold and, because of the heat treatment process, is now easily and readily assayed by standard fire assay techniques. It is
anticipated that incorporating this additional step into the Company’s flow chart renders process optimization testing
much easier and will allow this phase of the development program to be concluded more quickly.

Technical achievements considered
to be a major breakthrough
In the past few months the precise
nature of the gold contained in the Clarkdale slag has been determined. Test work done with high resolution microscopes –
a Scanning Electron Microscope (“SEM”) and a Transmission Electron Microscope (“TEM”) – have photographed
and measured the gold contained within sulfides and further encapsulated by a highly refractory silicate very resistant to thermal
and chemical attack. This explains the difficulty in fire assaying the gold or using ambient temperature strong reagent leaching.
Further, the gold is present as colloids (very small particles) less than 100 nm in size which is 1,000 times less than the width
of a human hair. [This microscopic size is in the range of most of the gold contained within the Carlin Trend in Nevada –
one of North America’s richest gold deposits that went undetected for decades due to the small “invisible” gold
particles. The Carlin Trend material was also very difficult to assay and process until the true nature and deportment of the gold
was determined.] The temperature required to break the silicate coating of the Clarkdale slag material exceeds standard fire assay
temperature which is why the gold is not captured in the lead collector used in a standard fire assay. Specialized grinding using
High Pressure Grinding Rolls (“HPGR”) and high temperature leaching used in the current proposed process flow diagram
aid in breaking this coating, oxidizing the sulfide, and converting the gold from a colloid to a charged ionic form in solution.
Jim Murray, the Company’s Project
Manager, noted that “This recent discovery of the true nature of the gold explains the difficulty thus far in analyzing the
slag material as well as liberating and capturing the gold contained. Most common technology used to capture gold from solution,
including electro-winning and ion exchange resin has had only limited success up to this point, because the only gold that was
being captured was the quantity of gold that had been converted into a charged ionic form, leaving the remainder of the colloid
gold behind. The additional high temperature pre-treatment, bench scale test work, which is underway, suggests that the gold in
solution exiting the autoclave will be much easier to capture and convert to metallic gold.” Mr. Murray also indicated that
“The conditions described above, which tend to mask gold content and show only ionic gold, may understate the true quantity
of gold present in the Clarkdale slag material.”
Testing using this process thus far
has verified the prior test results achieved and reported by the Company of goldgrades between 0.4 to 0.6 ounces per ton (average).
The processed material being derived from the heat treated slag is also much easier to be analyzed using standard analytical techniques.
Small autoclave tests conducted on the glass from the heat treatment have produced up to an 85% extraction of gold into the pregnant
leach solution (“PLS”) solution.
The PLS solutions have been treated
with ion exchange resin to remove the gold from solution. Fire assays of the gold impregnated resin indicate up to a 60% extraction
of the gold from the PLS into gold fire assay beads (gold in hand). While not yet optimized, this is a significant improvement
over previous attempts to capture the gold as metal by ion exchange resin.
All of these tests thus far have been
limited to a small 6 liter test autoclave. To provide more definitive process results, the Company has purchased (and expects
delivery within 2 weeks) a much larger heat treating unit, to produce sufficient treated slag to allow running the larger 900 liter
pilot autoclave. This will provide a sufficient volume of PLS for a final determination of recoverable gold by ion exchange resin,
as well as, allowing the testing of other methods of gold removal from solution to determine the method allowing optimal recovery
of gold from solution.
Other positive developments
In addition to the breakthrough discussed
above, as a byproduct of this new process, the high temperatures produce a high quality iron product grading 75 to 85% iron content
in a pelletized form. The high quality of the iron and its pellet size form make it a readily marketable product for sale to the
China, Korea, or India markets. The Company believes that further optimization testing will result in greater than 90% iron as
achievable and will secure a premium price selling either into the scrap iron or pig iron market. Test work is underway to maximize
iron content while maintaining gold recovery.
The existing railroad spur on the Clarkdale
Project Site connects to a major railroad for low cost transportation to a seaport or domestic market. It is believed that this
pre-treatment process may pay for itself or provide a net cash flow from the sale of the iron. To examine the efficacy of this
concept, Searchlight has engaged Samuel Engineering of Denver, Colorado to perform a preliminary assessment and marketing study.
This study has just been concluded and suggests that a marketable higher grade iron product could be made and sold as a byproduct
to generate net cash flow or reduce the overall costs of producing gold. Toward this end the Company has commenced contacting commercial
iron producers for expressions of interest.
This pilot scale test work should provide
sufficient process definition for a project feasibility study to be completed, allowing management to seek the financing to move
forward to commercialization of the Clarkdale Project.
Martin Oring, Searchlight Minerals
CEO, stated “This latest breakthrough has moved the project much closer to commercialization as well as potentially providing
extra unanticipated revenue through the sale of iron.” Mr. Oring went on to state “The gold results set forth
in the release have not yet been optimized, however, since the Company has been able to remove the iron as a saleable byproduct
through the additional step discussed, even at the current results, if repeatable, the project would be commercial. We are
looking forward to final definition of the process flow diagram and moving ahead to the bankable study to allow the project to
move to a commercial status.”
