Sterling Resources Announces Results of Final Well of Cladhan Appraisal Program

CALGARY, Alberta, June 3, 2011 -

Sterling Resources Ltd. ("Sterling" or the "Company") (TSXV: SLG)
announces the completion of drilling of the 210/30a-4X well on Block 210/30a
in the United Kingdom North Sea. This is the fourth well (third side-track)
drilled in the current four well campaign to further appraise the extent of
the Cladhan reservoir.

The 210/30a-4X well was drilled in the most southern limit of the
northern core area in a potentially separate channel, utilizing the
Transocean Prospect rig. The objectives of the 210/30a-4X sidetrack well were
to core the full reservoir section approximately one kilometre south and
approximately 60 feet updip of the oil bearing 210/30a-4 well, and evaluate
the southern fringe of the northern core area.

The 210/30a-4X well was drilled to a total measured depth (MD) of 10,614
feet encountering 171 feet gross, 105 feet net (vertical thickness) of high
quality Upper Jurassic sands. Almost 180 feet of core was successfully
recovered across the full reservoir section.

Petrophysical analysis of the interval showed five feet of oil-bearing
sand at the top of the interval with an Oil-Down-To at 10,177 feet True
Vertical Depth Subsea (TVDSS). An oil sample was obtained from the interval.
A further 100 feet of water-bearing sand was encountered below thin shale
which separates the top and bottom sands. A clear contact has not been
observed although the top and bottom sands appear to be in pressure
communication. The presence of a known Oil-Down-To bodes well for updip oil
in other channels with the same pressure regime.

Generally, reservoir quality is very good with porosities up to 25
percent, substantiated by measurements obtained while taking fluid samples.
These pressure measurements also confirm that the interval is over-pressured
on trend with the 210/30a-4Y well, but some 900 psi lower than the discovery
area. The implication of this information is that the southern fringe of the
northern channel area is in communication with the central channel, being
distinct from the main reservoir in the northern channel area. The well will
be suspended for possible re-use as a future development well at this
location or elsewhere after a sidetrack. With the completion of this four
well drilling campaign, RPS Energy will start a review of the Cladhan
resources with the intent of publishing an update report within a few weeks.

"Notwithstanding the presence of predominantly wet sands at this depth in
this separate channel compartment, we are encouraged by the presence of oil
in the top sand and by reservoir quality at this location. Further updip
prospectivity is certainly promising," remarked John Rapach, Sterling's Chief
Operating Officer. "We have proved that our current seismic model can
adequately predict sand thickness but reservoir quality definition is now
paramount for further appraisal and development drilling. Our next planned
subsurface activity is to complete full reprocessing and interpretation of
the existing seismic dataset incorporating all of the log, core, fluid and
pressure results obtained during this current drilling campaign.
Consequently, the next drilling campaign will probably commence in early
2012," noted Mr. Rapach.

"Our development planning is concentrating on either a subsea tie-back or
FPSO development of the main northern core area with further definition of
reserves and resources during our next drilling campaign. We are commencing
pipeline route and environmental survey work within the next few weeks,"
added Mr. Rapach.

Mike Azancot, Sterling's Chief Executive Officer, commenting on these
results noted that: "The current exploration and appraisal drilling campaign
on Cladhan has been successful in increasing the height of the oil column by
798 feet to 1228 feet in total. The extent of the development of the northern
core area is now better defined with this increase in oil column. The fan
area in the east of the field remains prospective as the results from the
210/30a-4Z well drilled in this campaign are not conclusive due to its
proximity to a major fault. Our plan towards development with options for
increased resource exploitation after further drilling is now underway with a
target for first oil in 2014."
