Erdene and APM Shareholders Vote in Favor of Plan of Arrangement

HALIFAX, NOVA SCOTIA--(Marketwire - Oct. 26, 2012) - Erdene Resource Development Corp. ("Erdene") (TSX:ERD) and Advanced Primary Minerals Corp. ("APM") (TSX VENTURE:APD) are pleased to announce the positive results from the special meetings of shareholders held on October 26, 2012.

At the special meetings of the shareholders of Erdene and APM, the shareholders of both companies voted in favour of a plan of arrangement ("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"). Morien is to be listed on the TSX Venture Exchange under the symbol "MOX". Erdene will continue under the same name and trading symbol.

Under the terms of the Arrangement, 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". Each existing shareholder of APM other than Erdene will receive one "Morien Share" for every 7.85 shares of APM that they own on the effective date.

Although the Arrangement was approved by the shareholders of Erdene and APM, it will not be effective until it is approved by the Supreme Court of Nova Scotia and final approvals are received from the Toronto Stock Exchange and the TSX Venture Exchange. It is expected these approvals will be obtained within the next ten days. Once the effective date is determined, a further news release will be issued.

At the Erdene Meeting, the Erdene shareholders also approved a deferred stock unit plan ("DSU Plan"), adopted by the Erdene board for the benefit of Erdene's employees and directors to form a part of Erdene's overall compensation strategy. The DSUs are intended to align the interests of directors and employees with the shareholders by tying compensation to share price performance. A detailed summary and the full text of the DSU Plan are included in the circular sent to the Erdene shareholders in connection with the meeting, which is available under Erdene's profile on SEDAR at www.sedar.com.
