Erdene Provides Update on Trans Altai Alliance

HALIFAX, NOVA SCOTIA--(Marketwired - April 22, 2016) - Erdene Resource Development Corp. (TSX:ERD) ("Erdene" or "Company"), announced today that the Company has agreed with Teck Resources Limited ("Teck") to extend the optional subscription date for 2016 for the Company's strategic alliance ("Alliance") in Mongolia by 60 days to June 23, 2016. The new subscription date coincides with the planned commencement of the 2016 field exploration program.

The Alliance with Teck was entered into in April, 2013, and was formed by the signing of option and private placement agreements (collectively, "Agreement") to fund and carry out mineral exploration in the Trans Altai region of southwest Mongolia. Under the terms of the Agreement, Teck has the option to subscribe for shares of Erdene, priced at the then current market plus 10%, until it has invested $3 million or acquired through subscriptions 19.9% of the outstanding shares of Erdene, whichever occurs first. A minimum of $500,000 is to be subscribed by Teck on each anniversary date of the closing of the Agreement to renew the Alliance. To date, Teck has subscribed for $2 million in Erdene shares and owns 11.4% of Erdene's issued and outstanding common shares. Excluded from the Alliance are the Company's Bayan Khundii Gold Project and Altan Nar Gold-Polymetallic Project.

A multi-year program of regional exploration, designed to identify porphyry and porphyry-related mineralization, has been underway since inception. The program has provided the Alliance with a significant amount of technical information that continues to be evaluated. During the 2015 program the Alliance was able to secure new exploration licenses within the targeted area and is now reviewing the potential for future acquisitions within the Mongolia licensing system. Upon renewal of the Alliance, the 2016 exploration program will consist of surface geochemical sampling, geological mapping and prospecting, and analysis of newly acquired satellite data.
