Starfield Resources Announces Remainder of Core Assay Results From 2007 Exploration Program

     /NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN
     THE U.S./

     Company Provides Update On 2008 Summer Exploration Program

     TORONTO, Aug. 13 /CNW/ - Starfield Resources Inc. (TSX: SRU / OTCBB:
SRFDF) today announced assay results of remaining core samples obtained from
15 holes drilled at the Company's Ferguson Lake project during the 2007 drill
program. The Company also provided an update on its current 2008 summer
exploration program.
     "We continue to be very encouraged by the size of the massive sulphide
deposit in the West Zone," said Andr� Douchane, President and Chief Executive
Officer. "In addition to the high concentrations of PGEs that we discovered
during our 2007 program, the nickel, copper and cobalt grades are equally
promising."
     The 2007 program, which consisted of 19 core holes, was focused on the
eastern part of the West Zone, and had two objectives. The primary objective
was the continued evaluation of the encouraging PGE mineralization that had
been encountered in previous drilling. This PGE mineralization is associated
with intervals containing low total sulphides (1%-5%) that occur in footwall
rocks several tens of meters beneath the massive sulphide lenses comprising
the West Zone. For this reason, assaying efforts were initially concentrated
on the lower parts of the 2007 drill holes, and those results were reported in
Starfield's February 25, 2008 news release.
     The second objective of the 2007 program was the continued definition and
evaluation of the massive sulphide mineralization comprising the eastern part
of the Main Zone. After the winter program concluded, it was not possible to
split and submit the core samples for assay before the end of the year.
Accordingly, these cores were split and submitted for analysis prior to
initiation of the 2008 drilling program in May of this year.
     "The majority of the 2007 drill holes continued to confirm the
continuity, thickness and grade of the known massive sulphide mineralization
within the eastern part of the West Zone," said Ray Irwin, Vice President of
Exploration.
     The assay results from the 15 holes in which massive sulphide
mineralization was observed are set out in the table below.

     Starfield's Diamond drilling, logging and sampling was overseen and
carried out by Ray Irwin, BSc, P.Geo, a Qualified Person in accordance with NI
43-101, who has reviewed this news release. The samples were prepared at Acme
Analytical Laboratory Ltd.'s (Acme Labs) facilities, in Yellowknife and
shipped to Acme's lab in Vancouver for analysis. Check assays were performed
by SGS in Lakefield, Ontario.

     Update on 2008 Exploration Program

     Since the most recent drilling program commenced in May 2008, 26 holes
have been completed, totaling 10,632 metres. Of the total, 24 were drilled in
the eastern half of the West Zone with the following objectives:

     -   Upgrade the current resource designation in the eastern part of the
         West Zone;
     -   Confirm continuity within individual massive sulphide lenses;
     -   Locally, extend known massive sulphide mineralization; and
     -   Further evaluate scattered, but locally strong PGE intersections
         obtained in previous drilling. Currently, PGE mineralization is
         believed to be associated with intervals of lower sulphide
         concentrations that are located in the footwall below the massive
         sulphide mineralization.

     In addition to the drilling on the West Zone, two core holes have also
been completed on the North Zone. These holes were purely explorative in
nature and were designed to begin assessing a strong northeast trending VTEM
anomaly located approximately 2 km north of the West Zone. This VTEM anomaly
is manifested on the surface by well developed gossans, which are similar in
appearance to the West Zone and possess weakly anomalous base and precious
metal values (up to 369 ppm Cu, 76 ppm Ni and 2,242 ppb Ag) in widely spaced
rock chip samples.
     All of the completed 2008 core holes have been logged, cores have been
split and samples submitted for assay. "We should have received at least a
third of the assay results from the first phase of 2008 drilling by now, but a
backlog at the laboratory has led to significant delays," said Mr. Douchane.
"We have started to receive partial assays from the first phase. When we
verify a few more complete holes we will release the results."
