HALIFAX, NOVA SCOTIA--(Marketwired - Feb 12, 2015) - Erdene Resource Development Corp. (ERD.TO) ("Erdene" or "Company") is pleased to announce it has granted Tian Poh Resources Limited ("Tian Poh"), a period of exclusivity to exercise an option to acquire an interest in Erdene's Zuun Mod molybdenum-copper project ("ZM Project" or the "Project") in southwest Mongolia.

Tian Poh can acquire and retain a 51% interest in the Project for US$4.8 million in cash and equity in Tian Poh, and by meeting certain work commitments (the "Transaction"). If Tian Poh exercises its option and meets milestones to retain its 51% interest (details discussed below), it will have the right to increase its interest to up to 100% through additional cash and/or equity payments. Erdene will retain a 1% net smelter return royalty, which will be subject to certain buy-down provisions. An option payment of US$50,000 plus US$200,000 in the form of a non-interest bearing debenture has been paid to Erdene. In the event Tian Poh does not exercise its option, the debenture will be convertible into Erdene shares. If Tian Poh exercises its option, the debenture proceeds will form part of the total purchase consideration. The exclusivity and option period expires on June 9, 2015. The Transaction is subject to approval from the Toronto Stock Exchange, the Australian Stock Exchange and Tian Poh's shareholders.

Tian Poh is an Australian listed (ASX), Singapore-based resource development company with a 100% interest in 10 coal and copper mineral concessions in Mongolia near the Chinese border. Tian Poh is part of the Poh Group Pte Ltd ("Poh Group" or the "Group") established by Singaporean businessman Mr Poh Kay Ping. Through a combination of strategic partnerships and joint ventures, Poh Group is made up of a dynamic group of companies involved in diverse industries across key developing and emerging markets throughout Asia. Two key areas of focus for Poh Group are resources and engineering. The Group's mineral resource investments in Mongolia are held under Tian Poh. These assets are mainly located in southern and southwestern Mongolia in close proximity to the Chinese border, giving Tian Poh ready access to China, the largest consumer of copper, molybdenum and coal. Poh Group has grown its engineering business segment through establishing successful strategic alliances with large state-owned companies.

Erdene management has considered this Transaction carefully in view of the overall strategic direction of the Company. Management recognizes that the Zuun Mod molybdenum-copper deposit offers significant long-term opportunity, however, in the current environment capital is scarce for major mining projects, like Zuun Mod. Management believes the best way to maximize shareholder value is by focusing on the advancement of its 100% owned Altan Nar gold - polymetallic project (see recent results, released February 9, 2015, click here) which management believes is nearer-term and will require a smaller capital investment. This Transaction provides an immediate injection of capital into Erdene with no dilution and, if Tian Poh elects to proceed following the exclusive option period, has the potential for significant cash and equity payments as the ZM Project advances. Furthermore, the structure of the Transaction provides considerable upside to Erdene through a sizeable equity interest in Tian Poh.

Khan Investment Management Ltd. ("Khan") was instrumental in identifying the opportunity and introducing the two parties. "We're delighted to have played a role in what is a tremendous value creating opportunity for two of our portfolio companies, and secure new, much-needed FDI [foreign direct investment] for Mongolia," said Travis Hamilton, Khan's Founder and Chairman. "Thanks to strong bi-partisan support for economic growth and FDI under Prime Minister Saikhanbileg, Mongolia appears set for a rebound. Tian Poh and Erdene are well positioned to benefit."

Significant Terms of the Transaction

Consideration for Exclusivity Period

1. Non-refundable exclusivity fee of US$50,000.
2. Acquisition of a US$200,000 non-interest bearing debenture ("Debenture") issued by Erdene. If Tian Poh does not exercise its option by June 9, 2015, the principal amount will be converted into common shares of the Company at CDN$0.14/share. If Tian Poh exercises its option, the Debenture will be deemed to be redeemed and the funds applied to the amount due on closing, which is expected to be on or about June 11, 2015 ("Closing").

Additional Consideration to Retain 51% Interest

In order to retain its 51% interest, Tian Poh must make further cash payments and issue shares of Tian Poh to Erdene and incur certain work expenditures on the Project as follows:

Cash Payments and Share Issuances

2. If Tian Poh exercises its option, Erdene shall be granted a 1% net smelter return royalty ("NSR"), payable after Tian Poh receives a return of the value of its consideration paid and work expenditures made. Once Tian Poh has fulfilled all of its obligations to retain its 51% interest, it shall have the right to reduce Erdene's NSR:
