VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 21, 2013) -

NOT FOR DISTRIBUTION TO U.S. NEWS WIRE SERVICES OR DISSEMINATION IN THE UNITED STATES

Astral Mining Corporation (News - Market indicators) ("Astral") announces that the annual general and special meeting of the shareholders of Astral will be held on Thursday, January 31, 2013 at Suite 700, 595 Burrard Street, Vancouver, British Columbia at 10:00 a.m. (Vancouver time) (the "Meeting").

At the Meeting, Astral's shareholders will be asked to, among other things, consider and to pass a special resolution (the "Arrangement Resolution") authorizing and approving the acquisition of all the issued and outstanding common shares of Astral by Orex Minerals Inc. (TSX VENTURE:REX) ("Orex") by way of a plan of arrangement (the "Arrangement"). Pursuant to the Arrangement, Orex will issue Astral shareholders 0.0834 of an Orex common share for each issued and outstanding Astral share held by an Astral shareholder (the "Exchange Ratio"). If the Arrangement becomes effective, the holders of outstanding Astral warrants and options will, upon exercise, be entitled to receive that number of Orex shares adjusted in accordance with the Exchange Ratio.

Astral's board of directors has unanimously determined that the terms of the Arrangement are fair and reasonable to Astral and its shareholders and unanimously recommends that Astral shareholders vote in favour of the Arrangement resolution at the upcoming meeting. Astral's board obtained a fairness opinion prepared by Ross Glanville & Associates Ltd. and Bruce McKnight Minerals Advisor Services. The board also considered a number of factors, including among others:

• the mineral property portfolio of Orex includes projects which are at a more advanced stage and offer better prospects for discovery of an economic deposit than the current mineral property portfolio of Astral;
  
  
• Astral shareholders, by receiving Orex shares under the Arrangement, would benefit from Orex's strong management team supported by a technical team with a history of exploration success and project advancement.
  
  
• Astral's mineral exploration projects would also benefit from Orex's fund-raising capabilities, broad following in the investment community, and strong cash position; and
  
  
• Orex will, upon completion of the Arrangement, have the financial resources and management and technical team to advance work programs on the Barsele Gold Project and Astral's projects and to investigate new mineral project acquisitions or other transactions.
  
  

For more information on the Arrangement, please see Astral's Information Circular as of December 13, 2012, the Fairness Opinion attached to the Circular, and other proxy materials which are available for review on SEDAR.

All shareholders are encouraged to vote by proxy at least 48 hours before the start of the annual general and special meeting or attend the meeting in person on January 31, 2013.
