Erdene Announces Private Placement

HALIFAX, NOVA SCOTIA--(Marketwired - May 21, 2015) - Erdene Resource Development Corp. (TSX:ERD) ("Erdene" or "Company"), is pleased to announce that it intends to undertake a non-brokered private placement ("Private Placement") to raise up to $1 million and has engaged the services of Altus Securities Inc. to act as advisor on behalf of the Company. The Company is also pleased to provide comment on the recently announced Oyu Tolgoi Phase II agreement.

Private Placement

Erdene is undertaking a non-brokered Private Placement to sell up to 7,142,857 units at a price of $0.14 per unit for gross proceeds of up to $1,000,000. Each unit will consist of one common share of the Company and one-half of one common share purchase warrant, with each whole common share purchase warrant ("Warrant") entitling the holder to purchase one common share of the Company at a price of $0.16 for a six month period from the closing date. Finder's fees will be paid on a portion of the Private Placement, consisting of up to 6.5% of the gross proceeds raised and up to that number of finder's fee warrants equal to up to 6.5% of the number of common shares issued on the Private Placement. Each finder's fee warrant will be exercisable into one common share of the Company at $0.16 per share, for a period of 12 months from the closing date.

Net proceeds of the Private Placement will be used to advance the Company's 100% owned Altan Nar gold-polymetallic project in southwest Mongolia and for general working capital purposes. The Company's current work plan includes process test work, evaluations of the mining, engineering, transportation, and marketing options and exploration and development related drilling.

The Private Placement is expected to close on or before June 5, 2015, and is subject to certain conditions, including, but not limited to, the receipt of all necessary approvals including the approval and acceptance by the Toronto Stock Exchange. All securities to be issued pursuant to the Private Placement will be subject to a four-month hold period from the closing date.

Oyu Tolgoi Agreement

The agreement announced this week between Turquoise Hill Resources, Rio Tinto and the Government of Mongolia, which sets out the basis for Phase II development of the giant Oyu Tolgoi copper-gold project, is, in the opinion of Erdene's executive management, a very significant milestone for Mongolia and all stakeholders involved in its mining industry. The agreement is expected to provide a pathway for an additional US$4 billion in financing to advance the project to the underground development phase to access the highest grade copper-gold ore zones. More importantly, this achievement signals that the Government of Mongolia ("GoM") is supportive of the mining industry and the foreign investment required to bring mineral deposits to production. This agreement is the most recent of a number of actions taken by the GoM in support of the mining industry over the past 24 months including favorable legislative changes and a re-opening of the mineral licensing system within which Erdene is actively participating. The Oyu Tolgoi project, which was discovered in the mid 1990's and produced 589,000 ounces of gold and 148,400 tonnes of copper last year, in only its 2^nd year of production, is a reflection of the mineral potential hosted in the Tian Shan trend located across the under-explored Gobi desert region of Mongolia. Erdene welcomes this news and improved environment for investors as it advances its new Altan Nar gold-polymetallic discovery towards production and pursues other endeavors in the rich copper-gold belts of southern Mongolia. As a company that has been actively exploring in Mongolia for the past 12 years, Erdene regards this announcement as confirmation by the GoM of its renewed commitment to promote the exploration and development of its vast mineral potential.
