Test results for Erdene Resource Development Corp’s Altan Nar Gold Project in southwest Mongolia reveal leach-amenable recoveries of greater than 80%.

Erdene’s CEO Peter Akerley says, “These results demonstrate the potential for rapid, high gold recoveries and, when combined with the extensive, shallow gold mineralization identified to date across the 5km-long Altan Nar project, are very encouraging. These results have the potential to significantly enhance the economics and development timeline, and provide further support for prioritizing drilling of multiple new targets in our next round of drilling in the latter half of 2013.”

Exploration and metallurgical testing of the epithermal Altan Nar project has determined two styles of mineralization occur in the system. The most significant finding from the studies is that the dominant gold mineralization style is amenable to cyanidation leach with recoveries of greater than 80%.

A series of 2 to 4 metre drill core composites were collected from holes across the property. These samples represent mineralization from the majority of the DZ and three additional prominent discoveries outside DZ.

With the exception of localized overprinting gold-arsenopyrite breccia zones, results show the majority of gold mineralization is highly amenable to cyanidation. Excluding two samples from the over-printing gold-arsenopyrite zone, 12 samples from across Altan Nar returned an average recovery of 81%. Future projects will be designed to maximize recoveries through additional grind size and retention time studies.

The Altan Nar gold discovery was made in late 2011 and included an initial drill hole with 55 metres @ 1.0 grams/tonne of gold and 12.0 grams/tonne of silver. Follow-up drilling extended the near-surface gold-silver mineralization over a strike length of 400 metres and it remains open.

Exploration in 2012 demonstrated continued mineralization at depth, continuity and wider intervals of mineralization in the northern portion of the DZ, and the discovery of multiple zones throughout the 5km trend.

Erdene is a Canada-based junior focused on the acquisition, exploration, and development of base and precious metals in Mongolia. Erdene is allied with Teck Resources to fund and explore a new copper porphyry discovery on a land holding 200km from the Chinese border in southwest Mongolia.
