Erdene Completes Trenching Program on the Altan Nar Gold-Silver Project

Three Trenches Over 250 Metre Strike Return Greater Than 1 g/t Gold Over Widths of 44 to 50 Metres

Editors' Note: There are three maps associated with this press release.

Erdene Resource Development Corp. (TSX:ERD) ("Erdene" or the "Company"), is pleased to report significant gold and silver results from the first phase of trenching that was completed earlier this month at the Company's 100% owned Altan Nar gold-polymetallic project in southwest Mongolia. Results have been obtained for the first four out of 28 trenches designed to test ten distinct mineralized zones across the 5.5 kilometre long Altan Nar target area.

"These early results have exceeded our expectations and have allowed us to meet our stated objective of establishing initial targets for open pit development at Altan Nar while pending results will allow us to prioritize new areas for the next phase of resource drilling" said Peter Akerley, Erdene President and CEO. "We believe the combination of these results and the extent of stockwork breccia uncovered in the remaining twenty-four trenches, combined with our previous results, demonstrate the potential for Altan Nar to host multiple, near-surface, gold-polymetallic deposits conducive to open pit mine development."

Results include three of four trenches returning excellent results over a 250 metre portion of the 400 metre long Discovery Zone. Gold-silver mineralized stockwork breccia zones were uncovered over wide intervals of 44 to 50 metres in each of the three trenches, all containing an average gold content of greater than 1.0 gram per tonne ("g/t"). Each contain wide, higher grade, intervals of 11 to 15 metres grading 2.4 to 3.0 g/t gold accompanied by 8 to 20 g/t silver.

A total of 1,858 metres of trenching resulted in 1,267, 1 to 2 metre samples have been sent to SGS Laboratory in Ulaanbaatar, Mongolia for multi-element analysis.

Discussion of Results

The objective of the trenching program is to further define the near-surface mineralization identified to date, improve the understanding of the gold mineralized system and prioritize new areas for the next phase of resource drilling. The exploration data generated by this program will also be used to develop conceptual plans for initial open pit development. These initial trench results, in conjunction with previous drill results, indicate the presence of a potential shallow, bulk-tonnage, gold-silver-lead-zinc mineralized system in the first of the 10 targets tested along the 5 kilometre trend.

The original trenching program, announced in October, 2013, was expanded from 1,200 metres to 1,858 metres due to the Company's early success in identifying and expanding mineralized zones. The surface expression of the Altan Nar project area is one of low relief with thin Quaternary cover over much of the area, interspersed with low rolling hills. The intense weathering of the altered, sulfide-rich, stockwork breccia zones leaves little surface expression of the targets and little indication of their size other than remnant quartz rubble. As a result, the extent of alteration and mineralization observed in the trenches commonly exceeded that indicated by surface expression. To date, the Altan Nar targets have not been tested below 250 metres vertical depth, however multiple holes have ended in zones of greater than 1 g/t gold.
