Senior executives of Erdene Resource Development Corp. took 10 visitors representing banks and securities firms from Canada, Australia, Mongolia and Hong Kong on a tour from June 17 to 20 of the company’s Mongolia operations. They saw drilling that had commenced on the Nomin copper-gold prospect on June 12 and upon completion, will continue on the Khuvyn Khar copper-silver prospect. Drilling on the Nomin prospect will initially include 1,500 meters in three to five holes targeting this new copper-gold discovery in southwestern Mongolia, and focus on geochemical, structural and geophysical targets in the vicinity of ancient shallow pits from which multiple grab samples returned an average of 2.2% copper and 1.7g/t gold.

Erdene has completed a preliminary drill program and a deep penetrating induced polarization geophysical survey over the Khuvyn Khar copper discovery in the northern portion of the Zuun Mod license. An interpretation of the drilling results and the new deep geophysics indicates that the copper mineralized zone appears to be structurally controlled in a zone of dacite porphyry in fault contact with granodiorite.

In 2011, Erdene will continue to expand its detailed program of regional exploration to identify areas, principally in southern Mongolia, with the potential to host porphyry related copper-gold-molybdenum mineralization.
