Ruddock Creek Project Update



    DSR - TSX.V

    VANCOUVER, March 14 /CNW/ - Doublestar Resources Ltd. ("Doublestar" or
the "Company") is pleased to provide the following summary of the results from
the 2006 exploration program on the Ruddock Creek Property, which is located
100 km north-northwest of Revelstoke in the Kamloops and Revelstoke Mining
Divisions, British Columbia (the "Property"). In 2006, Selkirk Metals Corp.
("Selkirk"), the operator, completed 14,740 metres of diamond drilling in 48
holes, mainly focused on better defining and extending the E Zone.

    E-Zone:
    -------

    The 2006 drill program confirmed Doublestar and Selkirk's understanding
that the mineralization at the E Zone consists of a planar sheet of massive
sulphides, which dips to the northwest at 45 degrees and plunges to the west
at approximately 40 degrees. Hole RD-06-153 is the most westerly drill hole
completed in 2006 and plots approximately 1.1 km west of the surface outcrop
of the mineralization. The massive sulphide horizon remains open downdip to
the west. Detailed drilling at the eastern end of the E Zone has shown the
mineralized body to be up to 400 m wide and varying in thickness from less
than 5 m to over 35 m. Sufficient drilling to constrain the width of the
mineralized horizon has only been completed over the easternmost 150 m of the
deposit. Sulphides occur as a series of semi massive to massive lenses of
sphalerite and galena hosted by a calc silicate rock and separated by
pegmatite bodies. The metamorphic event, which produced the pegmatites has
also remobilized the sulphides resulting in localized thickening of the
massive sulphide horizons.
    Structurally the deposit is continuous with the exception of the west
dipping E fault, which cuts the massive sulphides at approximately the mid
point of the current drill pattern, or about 600 m west of the surface
outcrop. In the immediate area of the E Fault the massive sulphide horizon
shows evidence of thinning due to movement along the fault plane, and a small
offset due to rotation of the units.

    The following table highlights the significant results from the 2006
drill program on the E Zone:

    Metallurgical work carried out by SGS Lakefield Research Limited on the
sulphide mineralization has shown the material to be composed dominantly of
sphalerite with lesser galena, pyrrhotite and pyrite. No significant
quantities of any deleterious trace elements have been detected. Testwork is
ongoing on the ore to determine the optimum method of processing, including a
DMS (heavy liquid separation) circuit to assess its amenability to upgrading
prior to floatation. Positive results with this process would allow the
incorporation of significantly lower grade material into resource calculations
and potentially into the production of direct shipping ore. As part of the
metallurgical program, Acid-Base accounting of the country rock and the ore
horizon has indicated that the host rock will not be acid producing.

    Creek Zone:
    -----------

    Drilling of the Creek Zone consisted of 10 holes, all of which
intersected the mineralized horizon and showed it to be continuous over a
100 m by 100 m area. This material is visually the same as the E Zone and the
assay results are similar. The drilling was concentrated around the area of
hole T-77-6 which is located approximately 500 m east of the Lower T Zone,
which is likely a continuation of the same horizon. The Creek Zone forms part
of a series of massive sulphide showings exposed at surface, which include the
Lower and Upper T Zones. In total these zones, which exhibit similar
characteristics, indicate a continuous sulphide horizon with a strike length
of over 1 km. These dimensions are similar to the dimensions of the E-Zone
that has been the focus of exploration on the Ruddock Creek Property to date.

drill program on the Creek Zone:

    Engineering and Environmental Studies:
    --------------------------------------

    Construction of an access road to the Light Lake core logging area
commenced in July of 2006 and by the end of the season had progressed to
within 600 m of the lake. This road will provide access to the planned camp
area for the 2007 activities. Selkirk and Doublestar expect to commence
underground work with the collaring of an exploration decline this summer. The
decline will be approximately 1 km in length and driven at a minus 15% grade.
It will intersect the E-Zone at or near its western extension and drill holes
RD-05-113 and RD-06-152. Cross cuts will be completed to both the east and
west to allow for the necessary delineation drilling and engineering.
Approximately 10,000 m of underground diamond drilling is planned. The site of
the decline has been chosen and will entail an additional 2 km of road
construction around Light Lake to the portal site.
    The baseline environmental studies required for project advancement were
initiated in the spring of 2006. This has entailed the establishment of a
permanent weather station, detailed systematic water quality studies covering
all drainages, wildlife and fisheries studies and surveys.

    Planned Exploration of Balance of the Ruddock Creek Sulphide System:
    --------------------------------------------------------------------

    The Ruddock Creek Property was initially discovered in 1960 and explored
by Falconbridge until 1963 and by Cominco from 1975 until 1977. This resulted
in the discovery of 12 zones of significant zinc and lead mineralization and
the definition of the "Ruddock Creek Sulphide System". Research has confirmed
that the sulphide mineralization is a "BHP SEDEX" deposit. The E, Creek and T
Zones are located at the eastern end of the "Ruddock Creek Sulphide System",
which has been defined by previous exploration to extend for over 5 km.
Previous exploration on the other zones within the Sulphide System included
surface mapping, sampling and shallow drilling, resulting in the discovery of
massive sulphide mineralization in all zones over widths from 2 m to over
14 m. With the delineation of sufficient tonnage, any one of these zones would
become a new target for development. Significant drill results from these
zones are included in the following table:

    In addition to the underground exploration and development program on the
E-Zone, a $4.5 million exploration program of geological mapping, trenching
and diamond drilling to evaluate the potential of the most prospective of
these zones is planned. This is expected to add further to the resource
outlined in the E-Zone and to the overall resource potential of the Ruddock
Creek Property.
    In summary, Selkirk and Doublestar have successfully met all objectives
of the 2006 exploration program, which has justified the plan to accelerate
development of the Ruddock Creek Property through an extensive 2007 program of
underground development, surface exploration and engineering studies. Selkirk
and Doublestar are now in the process of planning for this program and expect
operations to begin in April or May.
    Exploration on the Ruddock Creek Property is being conducted under the
supervision of the Selkirk's Qualified Person (as defined by NI 43-101), Jim
Chapman, P.Geo. All samples were analyzed by Acme Analytical Laboratories in
Vancouver utilizing the Group 7AR methodology.
    Doublestar Resources Ltd., holds an undivided 30% interest in the Ruddock
Creek Property under the terms of a joint venture agreement with Selkirk
Metals Corp. (TSX.V:SLK) who hold 70%. Selkirk is the Operator of the Ruddock
Creek Joint Venture. The merger between Selkirk and Doublestar announced
March 1, 2007 will, if approved, result in the combined companies holding a
100% interest in the Ruddock Creek Property.
    Doublestar also advises that it has terminated the Investor Relations
consulting agreement with M. William McCarty announced on August 25th, 2006.
The termination is consequent on the offer by Selkirk to acquire Doublestar by
plan of arrangement that was announced March 1, 2007. Incentive stock options
to acquire up to 80,000 shares of Doublestar will be cancelled in favor of a
$5,600.00 payment made to Mr. McCarty.
