Macarthur Minerals Limited Legal Proceedings: Further Update

THIS NEWS RELEASE IS NOT FOR DISTRIBUTION TO UNITED STATES SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

VANCOUVER, BRITISH COLUMBIA -- (Marketwire - Nov. 26, 2012) - Macarthur Minerals Limited (TSX:MMS) (OTCQX:MMSDF) (the "Company" or "Macarthur") provides an update regarding legal proceedings commenced by LPD Holdings (Aust) Pty Ltd ("LPD") and Mayson Associates Limited ("Mayson") against the Company, certain directors and officers of the Company, and Jaldale Pty Ltd in July 2012 ("July Proceedings"), the subject of previous announcements dated July 20, 2012 and August 24, 2012.

On November 21, 2012 the Supreme Court of Queensland heard applications to strike-out the July Proceedings by the Company and those directors and officers of the Company named as respondents ("Respondent Officers"). The Court ordered, among other things, that the July Proceedings be dismissed due to what her Honour described as a "fatal defect", namely that neither LPD nor Mayson were registered shareholders of the Company at the date the July Proceedings were commenced. The Company and the Respondent Officers sought their costs of the July Proceedings on the indemnity basis and the matter has been adjourned to allow the parties to make further written submissions in that regard.

After commencing the July Proceedings, LPD has re-registered as a shareholder of the Company and the Company has now been served with new proceedings commenced by LPD on November 20, 2012 ("New Proceedings"). The New Proceedings are similar to the July Proceedings but do differ in some material respects. In particular, the claims against Jaldale Pty Ltd and the officers of the Company, David Taplin and Joe Phillips, have been dropped and certain grounds for relief have also been abandoned. In addition, Mayson is not an applicant in the New Proceedings. LPD is yet to file a Statement of Claim in respect of the New Proceedings, but is expected to do so in early December 2012.

The Company is of the view that, as with the July Proceedings, the New Proceedings are without merit. The Company intends to vigorously defend the New Proceedings.

The Company will consider seeking security for costs from LPD in relation to the New Proceedings. LPD consented to providing security for costs in the July Proceedings.
