An independent review by Gaffney, Cline & Associates estimated that within the 250 square-mile delineated portion of Block 20, and within the Hollin formation, there are between 4 and 12 billion barrels of oil originally-in-place. Canadian reporting standards and, in particular, the Canadian Oil and Gas Evaluation Handbook, stipulate that, until it can be established that oil will flow to the surface, original-oil-in-place must be reported as "undiscovered resources".Ivanhoe has also commenced a 190 kilometre 2-D seismic program on the southern part of the Pungarayacu Block. Ivanhoe anticipates that this initial phase of shooting and processing of 2-D seismic will be completed in early July. The seismic data will be used to better identify sub-surface structures, assist in the selection of future drilling locations and possibly determine deeper geologic trapping systems which may contain lighter quality crude products. HTL represents a unique competitive advantage as Ivanhoe executes its heavy oil business plan around the world. HTL has demonstrated the ability to upgrade a wide range of heavy oil feedstocks with significant variability in characteristics into a more valuable and marketable synthetic crude oil meeting pipeline specifications. HTL eliminates the need for diluent and blend agents for transport, and eliminates, or virtually eliminates, the need for natural gas for steam generation for thermal recovery. These HTL advantages all come to bear in Pungarayacu in Block 20, as well as in many other heavy oil fields in Ecuador, where access to natural gas and blend agents is restricted, and heavy oil is abundant. Ivanhoe Energy Inc. is an independent, international oil and gas company with a focus on heavy oil development and production using advanced technologies, including its proprietary, patented heavy to light upgrading process (HTL™). Core operations are in Canada, Ecuador, China and Mongolia, with business development opportunities worldwide. Ivanhoe's shares trade on the NASDAQ Capital Market with the ticker symbol IVAN and on the Toronto Stock Exchange under the symbol IE.

Cautionary Statement Regarding Undiscovered Resources: There is no certainty that the Block 20 oil-in-place identified to date can be made to flow to the surface such that these undiscovered resources can be upgraded to a higher resource category nor that it will be commercially viable to produce the resources. FORWARD-LOOKING STATEMENTS: This document includes forward-looking statements, including forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, statements concerning the estimated quantities of gas in each target in the Guan structure, the anticipated amount of time required for, and the estimated cost of, drilling, testing and casing the Yixin-2 and Zitong-1 wells, and other statements which are not historical facts. When used in this document, the words such as "could", "plan", "estimate", "anticipate", "intend", "may", "potential", "should", and similar expressions relating to matters that are not historical facts are forward-looking statements. Although Ivanhoe Energy and Sunwing Energy believe that their expectations reflected in these forward-looking statements are reasonable, such statements involve risks and uncertainties and no assurance can be given that actual results will be consistent with these forward-looking statements. Important factors that could cause actual results to differ from these forward-looking statements include the possibility that the company will be unable to raise financing, the potential that the company's projects will experience technological and mechanical problems, geological conditions in reservoirs may not result in commercial levels of oil and gas production, the availability of drilling rigs and other support services, uncertainties about the estimates of the reserves, the risk associates with doing business in foreign countries, environmental risks, changes in product prices, our availability to generate cash flow and raise capital as and when required, competition and other risks disclosed in Ivanhoe Energy's Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission on EDGAR and the Canadian Securities Commissions on SEDAR.
