were prepared, the statements are not a guarantee of Entrée’s future performance and are based on numerous assumptions regarding present and future business strategies, local and global economic conditions, legal
proceedings and negotiations and the environment in which the Company will operate in the future, including the price of copper, gold and silver, and the status of the Company’s relationship and interaction with the
Government of Mongolia, Oyu Tolgoi LLC (“OTLLC”), Rio Tinto and Turquoise Hill Resources. With respect to the construction and continued development of the Oyu Tolgoi underground mine, important risks, uncertainties
and factors which could cause actual results to differ materially from future results expressed or implied by such forward-looking statements and information include, amongst others, the timing and cost of the construction and
expansion of mining and processing facilities; the timing and availability of a long term power source for the Oyu Tolgoi underground mine; the ability of OTLLC to draw down on the supplemental debt under the Oyu Tolgoi
project finance facility and the availability of additional financing on terms reasonably acceptable to OTLLC, Turquoise Hill and Rio Tinto to further develop Oyu Tolgoi; delays, and the costs which would result from delays, in
the development of the underground mine; projected copper, gold and silver prices and demand; and production estimates and the anticipated yearly production of copper, gold and silver at the Oyu Tolgoi underground mine.
Other uncertainties and factors which could cause actual results to differ materially from future results expressed or implied by forward-looking statements and information include, amongst others, unanticipated costs,
expenses or liabilities; discrepancies between actual and estimated production, mineral reserves and resources and metallurgical recoveries; the size, grade and continuity of deposits not being interpreted correctly from
exploration results; the results of preliminary test work not being indicative of the results of future test work; fluctuations in commodity prices and demand; changing foreign exchange rates; actions by Rio Tinto, Turquoise Hill
and/or OTLLC and by government authorities including the Government of Mongolia; the availability of funding on reasonable terms; the impact of changes in interpretation to or changes in enforcement of laws, regulations

government approvals, consents and permits; the availability and cost of necessary items such as power, water, skilled labour, transportation and appropriate smelting and refining arrangements; and misjudgements in the
course of preparing forward-looking statements. In addition, there are also known and unknown risk factors which may cause the actual results, performances or achievements of Entrée to be materially different from any
future results, performance or achievements expressed or implied by the forward-looking statements and information. Such factors include, among others, risks related to international operations, including legal and political
risk in Mongolia; risks associated with changes in the attitudes of governments to foreign investment; risks associated with the conduct of joint ventures; discrepancies between actual and anticipated production, mineral
reserves and resources and metallurgical recoveries; global financial conditions; changes in project parameters as plans continue to be refined; inability to upgrade Inferred mineral resources to Indicated or Measured mineral
resources; inability to convert mineral resources to mineral reserves; conclusions of economic evaluations; future prices of copper, gold, silver and molybdenum; failure of plant, equipment or processes to operate as
anticipated; accidents, labour disputes and other risks of the mining industry; delays in obtaining government approvals, permits or licences or financing or in the completion of development or construction activities;
environmental risks; title disputes; limitations on insurance coverage; as well as those factors discussed in the section entitled “Risk” in Entrée’s most recently filed Management’s Discussion & Analysis and in the section

statements.
Entrée's exploration activities are under the supervision of Robert Cinits, P.Geo., Vice President, Corporate Development of Entrée. Mr. Cinits is a “qualified person” as defined in National Instrument 43-101- Standards of
Disclosure for Mineral Projects (“NI 43-101”). Mr. Cinits has approved the technical information in this presentation.
All minerals reserves and mineral resources have been calculated in accordance with the standards of the Canadian Institute of Mining, Metallurgy and Petroleum and NI 43-101. Cautionary Note to United States Investors:
United States investors are advised that while the terms “Measured mineral resources”, “Indicated mineral resources” “Inferred mineral resources” and “Probable mineral reserves” are recognized and required by Canadian
regulations, the United States Securities and Exchange Commission (“SEC”) does not recognize them. United States investors are cautioned not to assume that any part or all of the mineral deposits in these categories will
ever be upgraded to a higher category, or converted into mineral reserves. Inferred mineral resources have a great amount of uncertainty as to their existence, and as to their economic and legal feasibility. Under Canadian
rules, estimates of Inferred mineral resources may not form the basis of feasibility or other economic studies. United States investors are cautioned not to assume that all or any part of an Inferred mineral resource exists, or is
economically or legally minable. Disclosure of “contained ounces” is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute reserves
as in place tonnage and grade without reference to unit measures. Accordingly, information contained in this presentation containing descriptions of the Company’s mineral properties may not be comparable to similar
information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.
The information in this presentation is for informational purposes only. Readers should not rely on the information for any purpose other than to gain general knowledge of Entrée. This information is not intended to be, and
should not be construed as, part of an offering or solicitation of securities.
