Ivanhoe Mines Ltd.: SouthGobi Energy Resources Has Reported a Revision of the Previous Independent Resource Estimate for the West Field at Its Ovoot Tolgoi Coal Mine in Mongolia

New Appointments to SouthGobi's Management and Resource Development Team

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 20, 2009) - Ivanhoe Mines (TSX:IVN)(NYSE:IVN)(NASDAQ:IVN) has been advised that SouthGobi Energy Resources has issued a restatement of coal resources in one portion of SouthGobi's Ovoot Tolgoi coal mine in southern Mongolia following the discovery of errors in a 2008 resource estimate that had been prepared by an independent, third-party consultant.

The restatement, covering only the West Field portion of the coal project, was contained in a news release issued today by Gene Wusaty, Chief Operating Officer of SouthGobi Energy Resources Ltd. (TSX VENTURE:SGQ). SouthGobi reported that as a result of the consultant's errors, there was an overstatement of the extent of resources in the West Field that were calculated effective June 20, 2008, and reported by SouthGobi on July 31, 2008, primarily in the indicated and inferred categories.

However, SouthGobi also said that the current resource estimates for the separate South-East Field and the Ovoot Tolgoi underground project remained correct and unaffected by the West Field overstatement. Mining at Ovoot Tolgoi under the current plan also is not impacted because the operations are based on an earlier, confirmed estimate of the West Field coal resources as of December 31, 2006.

SouthGobi will appoint a major international engineering firm to complete a new Technical Report for Ovoot Tolgoi, which is expected to be completed later in 2009. SouthGobi expects that this new report will incorporate outstanding data obtained from drilling to the end of 2008 and redesign the surface mine to a depth of 300 metres from the present 250 metres. In addition, the new Technical Report will update the resource models and delineate reserves based on at least a pre-feasibility level of engineering.

SouthGobi's management believes this new report will demonstrate the potential of the Ovoot Tolgoi coal deposit. SouthGobi made considerable progress in identifying additional resources at Ovoot Tolgoi in 2008, drilling over 23,200 metres, down to a depth of 800 metres in the West Field. In addition, there are 3,800 metres of drill data from 2007 in the South-East Field that still require modelling. Based on 2008 drill data the coal potential is continuous along strike and at depth. "We are very encouraged with the results from drilling completed in 2008 and are confident we will be able to establish additional resources," Mr. Wusaty said. "We are planning further drilling this summer, which also is intended to expand the resource at Ovoot Tolgoi."
