DOUBLESTAR RESOURCES LTD. INFORMATION CIRCULAR MAILED TO SHAREHOLDERS

June 15, 2007

VANCOUVER, British Columbia - Doublestar Resources Ltd. (TSX-V: DSR) ("Doublestar") is pleased to announce that the Management Information Circular and Proxy relating to the annual general meeting of Doublestar and the proposed business combination between Doublestar and Selkirk Metals Corp. (TSX-V: SLK) ("Selkirk") has been mailed to the Doublestar shareholders.

All shareholders are invited to attend an annual general and special meeting of the shareholders of Doublestar to be held at the Westin Grand Hotel, 433 Robson Street, Vancouver, British Columbia on Thursday, July 12, 2007 at 11:00 a.m. (Vancouver time).

The purpose of the meeting will be to ask shareholders to approve the proposed acquisition of Doublestar by Selkirk (the "Transaction").  If approved, the Transaction will be completed by way of a Plan of Arrangement under which each Doublestar Class "A" share will be exchanged for one-half of one common share of Selkirk (the "Selkirk Shares").  Further details concerning the Transaction can be found in the Management Information Circular which is being filed on SEDAR today and will be available at www.sedar.com.

The Board of Directors of Doublestar believes that the Transaction is in the best interests of the shareholders and Doublestar, and recommends that shareholders vote to approve the Transaction.

In furtherance of the Transaction, Doublestar and Selkirk have entered into an Amended and Restated Arrangement Agreement dated June 7, 2007 that supersedes the original Arrangement Agreement signed with Selkirk on April 5, 2007.  The Amended and Restated Arrangement Agreement sets out the formal terms and conditions for the Transaction.

The principal changes effected by the Amended and Restated Arrangement Agreement are: (i) to amend the date by which certain events are to occur with respect to the Transaction; and (ii) to provide that Selkirk may elect to make cash payments to Doublestar shareholders otherwise entitled to receive fewer than 10 Selkirk Shares in lieu of Selkirk issuing Selkirk Shares to such Doublestar shareholders.

In connection with the Transaction, Doublestar and Selkirk commissioned the preparation of a technical report dated effective June 12, 2007 and titled "National Instrument 43-101 Technical Report on the Ruddock Creek Property" (the "Ruddock Creek Technical Report").  The Ruddock Creek Technical Report was prepared by James (Jim) Chapman, P. Geo., a "qualified person" for the purposes of National Instrument 43-101 - Standards of Disclosure for Mineral Projects ..  Doublestar and Selkirk currently hold jointly the Ruddock Creek Project in southeast British Columbia (Doublestar 30%; Selkirk 70%).

The Ruddock Creek Technical Report describes the results of the 2006 exploration program at Ruddock Creek as well as results from previous years.  The objectives of the 2006 exploration program have been met, 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.  Doublestar and Selkirk have completed the planning process for this program and operations commenced in early May.

The 2007 program is expected to commence with a 10,000 metre surface drilling program.  This work will start with expanding the known mineralized occurrences at the Q, R and U showings in Oliver Creek.  As conditions permit the drills will move up to the Creek Zone to expand the mineralized horizon defined by the 2006 drilling.  Definition drilling of the near surface portion of the E Zone will likely commence in July.  The underground program will entail the collaring of an exploration decline this summer followed by underground drilling.

A full text version of the Ruddock Creek Technical report is being filed on SEDAR today and will be available at www.sedar.com ..
