Erdene Closes $1,715,000 Financing Pursuant to Private Placement Through Mongolian International Capital Corporation Provides Update on Altan Nar Gold Project Drilling

HALIFAX, NOVA SCOTIA -- (Marketwire) -- 11/28/11 -- Erdene Resource Development Corp. (TSX: ERD) ('Erdene' or 'Company'), is pleased to announce that it has closed $1,715,000 of a private placement announced on November 16, 2011 and issued 4,287,500 shares at $0.40 per share. The offering was led by Mongolian International Capital Corporation ('MICC').

'We are tremendously pleased to receive the support of Mongolian shareholders, providing them with an opportunity to share in the excitement of what we believe is a significant new gold discovery at Altan Nar,' said Peter Akerley, President and CEO. 'This project is an important addition to our cornerstone Donkin Coal and Zuun Mod Molybdenum-Copper projects.'

MICC, the broker for the transaction, is the oldest and leading full service investment bank in Mongolia, providing investment banking, equity research, securities underwriting, and brokerage services to Mongolian and international clients.

'Since the discovery of Oyu Tolgoi by Ivanhoe Mines, Mongolians have been eager to participate and share in the risks and rewards through investment in the mineral exploration sector' ' said Achit Erdene Darambazar, President and CEO of MICC. 'We are very pleased to have the opportunity to work with companies like Erdene which have the potential to create significant value for our clients and are serious about engaging local stakeholders'.

All securities issued pursuant to the private placement are subject to a hold period expiring March 29, 2012. The Company paid a cash commission of $102,900 to MICC in connection with the closing of the financing.

Net proceeds of the Private Placement will be used for exploration of the Company's projects in Mongolia and working capital. Exploration expenditures will primarily be directed to the Altan Nar epithermal gold project. Initial drilling results from this discovery, announced on October 12, 2011, included 55 metres of 1.02 g/t gold and 12 g/t silver, including 23 metres of 2.07 g/t gold and 23 g/t silver in discovery-hole TND-09. A 3,000 metre, 18-hole drilling program was recently initiated to follow-up on the initial discovery and to test coincident geochemical-gold and geophysical anomalies in a 2 kilometre by 3 kilometre area (see press release dated November 10, 2011). To date, seven of the planned 18 holes have been completed, testing an area up to 600 metres north of TND-09. These holes have intersected multiple zones of sulphide-bearing epithermal breccias, similar to those intersected in the discovery hole.

Remaining drilling will test targets south from the discovery hole over a 500 metre strike length and additional geophysical targets to the northwest parallel to the discovery zone where surface rock samples returned in excess of 3 g/t gold. Drilling to date has concentrated on near surface mineralization (approximately 150 metres vertically) with geophysical anomalies and mineralized drill hole intersections open at depth and along strike. Initial samples have been delivered to the SGS laboratory which has a standard four to six week period to complete the analysis.
