HALIFAX, NOVA SCOTIA--(Marketwire - Nov. 2, 2012) - Erdene Resource Development Corp. ("Erdene") (TSX:ERD) and Advanced Primary Minerals Corp. ("APM") (TSX VENTURE:APD) are pleased to announce that the plan of arrangement ("Arrangement") involving Erdene, APM and Erdene Resources Inc., a wholly-owned subsidiary of Erdene, was approved by the Supreme Court of Nova Scotia on November 1, 2012. The effective date of the Arrangement ("Effective Date") will be November 9, 2012.

At the special meetings of the shareholders of Erdene and APM, held on October 26, 2012, the shareholders of both companies voted in favour of the Arrangement. Under the terms of the Arrangement, Erdene will separate its North American projects, consisting primarily of its 25% interest in the Donkin Coal Project, from its Mongolian metals exploration projects, which will stay within Erdene. The Donkin Coal Project will become the major asset of a new amalgamated company to be called Morien Resources Corp. ("Morien"). The shares of Morien ("Morien Shares") will be listed on the TSX Venture Exchange under the symbol "MOX". Erdene will continue under the same name and trading symbol.

On the Effective Date, the share capital of Erdene will be reorganized and each existing Erdene share will be exchanged for one-half of one "Erdene New Share" and one-half of one Morien Share. On the amalgamation of APM and ERI, each shareholder of APM (including Erdene) will receive one (1) common share of Morien for every 7.85 shares of APM owned by such shareholder. Erdene will distribute to the Erdene shareholders one-half of one Erdene New Share and one-half of one Morien Share for each existing common share of Erdene.

Detailed disclosure of the Arrangement can be found in the management information circulars prepared by each of Erdene and APM, dated September 25 and 26, 2012, respectively, both of which are available on SEDAR.
