Consolidating our Senior Company Status – The EMC Transaction Conference Call June 4, 2007  SXR – Toronto Stock Exchange, Johannesburg Stock Exchange EMC – Toronto Stock Exchange; EMU - NYSE Arca

Cautionary Statement Readers are advised to refer to independent technical reports containing detailed information with respect to the material properties of Uranium One and EMC. These technical reports are available under the profiles of Uranium One and UrAsia Energy Ltd., in the case of Uranium One, and EMC at www.sedar.com and provide the date of each resource or reserve estimate, details of the key assumptions, methods and parameters used in the estimates, details of quality and grade or quality of each resource or reserve and a general discussion of the extent to which the estimate may be materially affected by any known environmental, permitting, legal, taxation, socio-political, marketing, or other relevant issues. The technical reports also provide information with respect to data verification in the estimation. This presentation uses the terms "measured", "indicated" and "inferred" resources as defined in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects. United States readers are advised that while these terms are recognized and required by Canadian securities laws, the SEC does not recognize them. Readers are cautioned not to assume that all or any part of the mineral deposits in these categories will ever be converted into reserves. In addition, "inferred resources" have a great amount of uncertainty as to their existence and economic and legal feasibility and it cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Readers are cautioned not to assume that all or any part of an inferred resource exists or is economically or legally mineable. Mineral resources are not mineral reserves and do not have demonstrated economic viability. Scientific and technical information contained herein with respect to EMC’s resources has been reviewed on behalf of EMC by Dr. Art Ettlinger, M.Sc., Ph.D.,P. Geo., Chief Geologist for EMC and a Qualified Person for the purposes of NI 43-101. Scientific and technical information contained herein in respect of the Dominion Uranium Project including the Dominion Dumps has been reviewed on behalf of Uranium One by Dr. R.A. Stewart, Pr.Sci.Nat. (SACNASP), MGSSA, Vice President, Geology and Exploration, Uranium One. Scientific and technical information contained herein in respect of the Honeymoon Project and the East Kalkaroo, Goulds Dam and Billeroo properties has been reviewed on behalf of Uranium One by Mr. C. Skidmore, BScHons MAppSc MAusIMM, Vice President, Exploration, Uranium One. Both Dr. Stewart and Mr. Skidmore are qualified persons for the purposes of NI 43-101. Scientific and technical information contained herein in respect of the Adkala Uranium Mine, the South Inkai and Kharasan Uranium Projects and the Sheep Mountain Property has been reviewed on behalf of Uranium One by C. Stewart Wallis, P.Geo. Consulting Geologist . Mr. Wallis is a qualified person for the purposes of NI 43-101. All historical resource estimates quoted herein are based on prior data and reports obtained and prepared by previous operators and certain other information. The historical estimates should not be relied upon. No qualified person (as defined by NI 43-101) has done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. Neither EMC nor Uranium One has completed the work necessary to verify the classification of the mineral resource estimates. Neither EMC nor Uranium One is treating the historical estimates as current mineral resources or mineral reserves as defined in sections 1.2 and 1.3 of NI 43-101. Properties containing historical resource estimates will require further evaluation. Historical estimates referred to herein as Russian P1 resources are derived from Kazatomprom documents, an entity of the government of Kazakhstan. Although Russian P1 resources do not meet Canadian Institute of Mining, Metallurgy and Petroleum (CIM) standards on mineral resource and reserve definitions, they are considered relevant because it has been demonstrated that in Uranium One’s experience in similar type deposits in Kazakhstan, the P1 resources can be reclassified as inferred resources through additional drilling. However, there is less confidence attributed to a P1 resource since a P1 resource is estimated on the basis of a lower drill density than an inferred resource. Certain of the statements made herein, including any information as to the timing and completion of the proposed transaction, the potential benefits thereof, the future activities of and developments related to EMC and Uranium One prior to the proposed transaction and the combined company after the proposed transaction, market position, and future financial or operating performance of Uranium One or EMC,are forward-looking and subject to important risk factors and uncertainties, many of which are beyond the corporations’ ability to control or predict. Forward-looking statements are necessarily based on a number of estimates and assumptions that are inherently subject to significant business, economic and competitive uncertainties and contingencies. Known and unknown factors could cause actual results to differ materially from those projected in the forward-looking statements. Such factors include, among others: uranium and gold price volatility; impact of any hedging activities, including margin limits and margin calls; discrepancies between actual and estimated production, between actual and estimated reserves and resources and between actual and estimated metallurgical recoveries; costs of production, capital expenditures, costs and timing of construction and the development of new deposits, success of exploration activities and permitting time lines; changes in national and local government legislation, taxation, controls, regulations and political or economic developments in Canada, the United States, South Africa, Australia, Kazakhstan or other countries in which either corporation does or may carry out business in the future; risks of sovereign investment; the speculative nature of uranium and gold exploration, development and mining, including the risks of obtaining necessary licenses and permits; dilution; competition; loss of key employees; additional funding requirements; and defective title to mineral claims or property. In addition, there are risks and hazards associated with the business of uranium and gold exploration, development and mining, including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins, flooding and gold bullion losses (and the risk of inadequate insurance or inability to obtain insurance, to cover these risks), as well as the factors described or referred to in the section entitled “Risk factors” in Uranium One’s Annual Information Form for the year ended December 31, 2006 which is available on SEDAR at www.sedar.com, and the section entitled “Risk factors” in EMC’s Annual Information Form for the year ended June 30, 2006 which is available on SEDAR at www.sedar.com and from the SEC at www.sec.gov and which should be reviewed in conjunction with this document. Accordingly, readers should not place undue reliance on forward-looking statements. Neither corporation undertakes any obligation to update publicly or release any revisions to forward-looking statements to reflect events or circumstances after the date of this document or to reflect the occurrence of unanticipated events.
