Selwyn Resources Ltd.: Highest Grade Intercept for Selwyn Project, Drilled in
Don Valley


VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 9, 2007) - Selwyn Resources
Ltd. (TSX VENTURE:SWN) is pleased to provide an update on recent drilling
activities in the Don Valley for the Selwyn Project. The results from the Don
Valley are very encouraging and continue to expand the understanding of the
high-grade zinc-lead mineral potential at depth in Don Valley. The initial
drilling in Don Valley is focusing on the 4,200 metre length of Active Member
between the Don and HC West Deposits. 34 drill holes have been completed year
to date for a total of 10,152.36 metres, and 4 drill holes are in-progress in
Don Valley for an additional 892 metres. The location of the new drill holes
can be found on drill plan maps available at www.selwynresources.com.

Highlights

- DON-074 intersecting 31.63 metres true thickness of the Active Member at a
depth of 241.7 metres with a grade 10.20% zinc and 3.91% lead including 4.30
metres grading 35.97% zinc and 16.01% lead.

- DON-064 intersecting 9.00 metres true thickness grading 7.91% zinc and 2.28%
lead including 4.00 metres grading 9.48% zinc and 2.81% lead.

Don Deposit Deep Drilling

Drilling in the Don Deposit continues to target an area known to contain
high-grade zinc lead mineralized Active Member. The target area modeled to
potentially contain 20 to 25 million tonnes with a range of grades varying from
6% to more than 12% combined lead and zinc within an area of 600 by 600 metres
predominantly below open-pit limits (see May 31, 2007 news release). The
potential grade and tonnage of the target is conceptual in nature as there has
been insufficient drilling to define a resource. The current drilling is
targeted at defining this resource.

Recent assay results from DON-074 have yielded the single highest assay of
combined zinc-lead mineralized Active Member for the entire Selwyn Project
including all historical results from the XY Central high-grade underground
mineral resource. A 1.30 metre sample from 271.80 to 273.10 metres yielded
46.78% zinc and 17.94% lead; for an aggregate 64.72% combined zinc-lead. These
new assay results extend the high-grade zinc-lead Active Member from DON-044
that intersected 22.30 metres grading 8.94% zinc and 3.10% lead including 3.30
metres grading 24.21% zinc and 10.61% lead (see January 27, 2007 news release).

The very high-grade nature of the intercept in DON-074 demonstrates that the
high-grade underground target at Don Deposit can be directly compared to the
high-grade nature of the underground deposit at XY Central located 16
kilometres to the southeast that contains 7,394,860 tonnes of Indicated mineral
resources grading 9.88% zinc and 4.32% lead, which is flanked by 1,856,500
tonnes of Inferred mineral resources grading 10.41% zinc and 3.71% lead (see
April 2, 2007 news release). Similar historical results to DON-074 from the XY
Central high-grade underground mineral resource include surface drill hole
XYS-080 that intersected 16.4 metres true thickness grading 22.26% zinc and
10.18% lead and underground drill hole XYU-019 that intersected 4.57 metres
grading 21.42% zinc and 13.61% lead directly in the high-grade mineralization.
The high-grade zinc-lead mineralized Active Member of the Don Deposit remains
open to expansion along strike and at depth in terms of the high-grade
underground mineral potential.

Don East Deposit Open-Pit Target

Two drills continue to drill on the Don East Deposit with one drill having
recently moved to the HC West Deposit 2.2 kilometers to the southeast; noting
there remains a 1.0 kilometre untested gap between the Don East and HC West
Deposits. Zinc-lead mineralization of the Active Member in the Don East Deposit
is modeled to contain 40 to 60 million tonnes within an area of approximately
1600 by 600 metres with grades ranging from 6.0 to more than 12.0% combined
lead and zinc. Similar as to above, the potential resource is conceptual in
nature and additional drilling is required to define the resource. A
higher-grade target area of Active Member is currently being focused upon that
has been modeled to have the potential to host 20 and 30 million tonnes of
higher-grade zinc-lead mineralization ranging from 10 to 14% combined lead and
zinc (see April 2, 2007 news release).

DON-054, DON-057, DON-061, DON-063, and DON-064 were all successful in further
confirming the continuity of the zinc-lead mineralized Active Member through
the Don East Deposit. Of particular interest is DON-063, an infill drill hole
between DON-049 and DON-056; which intersected two zinc-lead mineralized
intervals of Active Member that could indicate structural duplication of the
Active Member thereby having positive implications for the mineral potential of
the Don East Deposit. It is also important to note that the infill drilling
continues to show higher-grade intervals within the open-pit target across the
Don East Deposit.

These most recent drill intersections of zinc-lead mineralized Active Member in
the Don East Deposit continue to expand the mineral potential in a
northwesterly direction by 440 metres from the extents defined in the 2006
definition drilling, as well as increasing confidence in the known mineral
inventory. All of the drill intercepts are within the open-pit environment that
remains open for expansion. It should be noted that there remains a 1.0
kilometre section of the Don Valley between the Don and Don East Deposits that
has yet to be tested by drilling.

The Selwyn Project exploration program is being reviewed by Vice President
Exploration, Mr. Jason Dunning, M.Sc., P.Geo. The onsite activities for the
Selwyn Project are directed by Exploration Manager, John J. O'Donnell, P.Geo.
Both Mr. Dunning and Mr. O'Donnell are Qualified Persons within the meaning of
National Instrument 43-101. All assay data has been through internal validation
of quality assurance and quality control. Selwyn has established a sampling and
assay control program with blind insertion of assay blanks, standards and
duplicates for the Selwyn Project; however, it should be noted that there is
also a quality control and quality assurance program in at ACME Analytical
Laboratories Ltd. ("ACME") that includes blanks, duplicates and standards. At
ACME, silver and base metal analyses are conducted by a 17-element, four-acid
digestion, ore-grade ICP-AES technique.

Note that all discussion of previous NI-43-101 compliant Indicated and Inferred
mineral resources are referenced in the March 2007 NI 43-101 report for the
Selwyn Project. In reviewing historical resources, all discussion of Indicated
mineral resources that predate introduction of NI 43-101 should be considered
as Inferred mineral resources. All historical Inferred mineral resources that
predate NI 43-101 should be considered as areas of mineral potential requiring
further definition through drilling. Historical mineral resources are
referenced in the June 2005 NI 43-101 report for Howard's Pass. Copies of the
reports can be viewed at www.sedar.com. Any areas discussed as possessing
mineral potential are not defined through drilling and are conceptual based
upon a detailed geological model. Further definition drilling is required prior
to discussing potential mineral resources as an accepted NI 43-101 mineral
resource classification.

Selwyn's focus is the exploration of its properties that make up the Selwyn
Project in the Yukon, which hosts large tonnages of zinc-lead mineralization.
The known deposits have the potential for the large scale production of zinc
and lead, at a time when major new mines are needed to ensure adequate future
zinc mine supply. As follow-up to the highly successful 2006 exploration
program, Selwyn Resources Ltd. is undertaking a $25 million exploration program
in 2007 to continue definition drilling of the XY, Anniv, and Don Valley (HC,
HC West, Don East, and Don) deposits.

This press release may contain forward-looking statements based on assumptions
and judgments of management regarding future events or results that may prove
to be inaccurate as a result of exploration and other risk factors beyond its
control and actual results may differ materially from the expected results.
Additional drilling is required to confirm the potential of the new discovery
areas and expansions of the current resource areas and the extension of the
higher grade deep mineralization to depth. Furthermore, there is no assurance
that the resources being defined can be developed as an economically attractive
mine, and there are many uncertainties associated with permitting and other
factors that could delay such development.
