Seismic Acquisition Completed on Manas' Block 14 in Mongolia

Manas announced that the seismic acquisition on block 14 has been completed without incident. The Chinese contractor DQE International Tamsag (Mongol) LLC acquired 162.4 km of 2D seismic, representing 54.1% of the total seismic program on blocks 13 & 14. All equipment and crew have been moved to block 13, where seismic acquisition has commenced. Manas anticipates that the seismic survey will be completed by the end of November 2010.

Manas intends to use the additional 2D seismic data to improve its technical database and its chance of drilling a successful exploration well. After interpretation of the full dataset, Manas will decide whether it is ready to drill one or more exploration wells or that it needs to acquire 3D seismic to define the drill prospects in better detail. Depending on this decision, Manas hopes to spud the first well in 2011.
