Star Gold Corp. Releases Metallurgical Test Results From Longstreet
Property
COEUR D'ALENE, ID--(Marketwired - May 13, 2014) - Star Gold
Corp. ("Star Gold" or the "Company") (OTCQB: SRGZ) announced today
that the Company released results from its metallurgical testing on
the Main Zone as part of its flagship property, the Longstreet
Property, located near Tonopah, Nevada (referred to herein as the
"Longstreet Property" or the "Longstreet Project"). These results
conclude six months of testing from material taken from the adit on
the Main Zone in 2013.
Star Gold engaged McClellend Laboratories, Sparks, Nevada to
undertake a metallurgical test work program on mineralized samples
from its Longstreet Project in west central Nevada. The technical
data generated from the metallurgical test work program provides
adequate data that will enable Star Gold to undertake and complete
a Preliminary Economic Analysis (PEA) on the Longstreet
Project.
The metallurgical test program was conducted in order to verify
earlier work on the leachability of surface and underground
gold/silver mineralization at the Longstreet Main Zone.
A heap leach cyanidation test program was undertaken on samples
selected from the currently defined resource which was identified
to contain two main types of mineralization, near the surface --
"oxide" mineralization associated with limonitic pseudomorphs of
pyrite, and "sulphide" mineralization associated with disseminated
pyrite. It is estimated that approximately 95% of the mineralized
deposit can be categorized as oxide with the remaining 5% as
sulphide.
Methodologically, the heap leach (column) cyanidation test
program utilized three master composite samples of oxide material.
The composite samples were identified as surface, underground and a
master blend, which was composited using a weighted average of
surface and underground sample. All samples were crushed to a size
of P80 of 19mm (80% of material smaller than 19mm) and were leached
for a period of 180 days. Gold extractions ranged from 83.1% to
88.9% indicating that the Longstreet Project deposit oxide is
amenable to gold heap leaching. Silver extractions for the column
tests were low and ranged from 15.4% to 20.0% (see chart).
Bottle roll testwork was carried out on a variety of crush size
products ranging in size from 100% -50 mm down to 80% -1.7 mm
material utilizing cyanide concentrations ranging from 1 to 5 g
NaCN/liter. The total leach time for all bottle rolls tests was 96
hours. Gold extractions ranged from 63% to 81% with silver
extractions ranging from 3.6% to 17.5%. A single bottle roll test
was conducted on a sample ground to a P80 of 75 microns in order to
examine the effect of fine grinding on silver recovery. Results
indicate a silver recovery of 60.6% indicating that fine grinding
would be required in order to liberate silver and improve recovery.
This was confirmed by the mineralogical examination of the bottle
roll tail sample which indicated that, due to the fine-grained
nature of the silver sulphide, recovery can be increased by further
liberation or exposure of the silver.
Future metallurgical testwork has been recommended to explore
load/permeability testing, reagent optimization, variability
testing and crushing testwork.
QUALIFIED PERSONS The metallurgical testwork was completed by
McClellend Laboratories, Sparks, Nevada, and reviewed by Mr. Alfred
S. Hayden, P.Eng., a Qualified Person under the terms of National
Instrument 43-101, a Canadian regulation with prescribed standards
for the reporting of mineral property technical information. The NI
43-101 standard is accepted in many jurisdictions. Alfred S.
Hayden, P.Eng., is independent of Star Gold Corp and has approved
the contents of this press release that pertain to the
metallurgical test work results and their interpretation.

The SEC normally only permits issuers to report
mineralization that does not constitute SEC Industry Guide 7
compliant "reserves" as in-place tonnage and grade without
reference to unit amounts. The term "contained ounces" is not
permitted under the rules of SEC Industry Guide 7. In addition, the
NI 43-101 and CIM Standards definition of a "reserve" differs from
the definition in SEC Industry Guide 7. In SEC Industry Guide 7, a
mineral reserve is defined as a part of a mineral deposit which
could be economically and legally extracted or produced at the time
the mineral reserve determination is made, and a "final" or
"bankable" feasibility study is required to report reserves, the
three-year historical price is used in any reserve or cash flow
analysis of designated reserves and the primary environmental
analysis or report must be filed with the appropriate governmental
authority.
