Oyuolgoi LLC is expected to begin production in its copper-gold mine in August 2012, ahead of schedule, according to T. Ganzorig, Deputy Chief of Erdenes MGL which partners with Ivanhoe Mines and Rio Tinto in developing the site. Ganzorig told reporters in Singapore that expedited construction has helped move the production date ahead of the earlier Ivanhoe Mines announcement commercial production would begin in the first half of 2013.
