The document discusses the Oyu Tolgoi mining project in Mongolia. It reports that all partners have confirmed that the investment agreement for the project has taken full legal effect. This will allow construction to begin in the second quarter of 2010 and first copper-gold production is expected in 2013. The Mongolian government has approved the feasibility study for the project. However, some MPs have asked for issues with the agreement to be resolved before allowing work to begin. The Finance Minister defended the agreement, saying critics are uninformed and arguing it is a good deal for Mongolia.
