Entrée Resources Files NI 43-101 Technical Report for its Interest in the

Entrée/Oyu Tolgoi Joint Venture Property

Vancouver, B.C., February 28, 201 8 – Entrée Resources Ltd. (TSX:ETG; NYSE American:EGI – the

“Company” or “Entrée”) is pleased to announce that it has today filed a National Instrument 43 -101 –

Standards of Disclosure for Mineral Projects (“NI 43-101”) technical report (“Report”) titled “Entrée/Oyu

Tolgoi Joint Venture Project, Mongolia, NI 43 -101 Technical Report” on its interest in the Entrée/Oyu

Tolgoi joint venture property in Mongolia. The Report has an effective date of January 15, 2018 and is

available on SEDAR at www.sedar.com and on the Company’s website. The Report relates to the press

release announced by the Company on January 15, 2018.

The Report discusses two development scenarios, an updated reserve case (“ 2018 Reserve Case”) and a

Life-of-Mine Preliminary E conomic Assessment (“ 2018 PEA”). The 2018 Reserve Case is based only on

mineral reserves attributable to the Entrée/Oyu Tolgoi joint venture from the first lift (“Lift 1”) of the Hugo

North Extension (“HNE”) underground block cave. The 2018 PEA is an alternative development scenario

completed at a conceptual level that assesses the inclusion of mineral resources from the second lift (“Lift

2”) at HNE and the Heruga deposit into an overall mine plan with mineral resources from HNE Lift 1.

Mr. Stephen Scott, President and CEO of Entrée, comments, “I am very excited that Entrée’s stakeholders

can now assess and appreciate the life-of-mine potential of Entrée’s joint venture interest. The 2018 PEA

demonstrates that Entrée’s interest is multi-generational, with potential to deliver over US$2.1 billion

dollars in undiscounted pre-tax cash flows just from Hugo North Extension Lifts 1 and 2 over the first 33

years of production. Post-tax, this equates to a net present value ( “NPV8%”) of US$277 million *. The

2018 PEA also brings resources from Heruga into the mine plan, but these are not scheduled to be mined

until much later in the life of the Oyu Tolgoi project. Although the Heruga deposit provides considerable

flexibility for future mine planning and development options, a dditional technical work is needed to

establish the mineral resources and costs with greater certainty and to enable investors to better

understand the true value of the Heruga deposit. Right now, the schedule outlined in the Report shows

the 2018 PEA has a duration of at least 77 years, from the start of HNE Lift 1 in 2021 until the completion

of Heruga in 2097, even without further exploration success.”

The 2018 Reserve Case is based only on mineral reserves attributable to the Entrée/Oyu Tolgoi joint

venture from Lift 1 of the H NE underground block cave. The 2018 Reserve Case NPV8% for HNE Lift 1 is

US$111 million. The 2018 PEA includes Indicated and Inferred resources from H NE Lifts 1 and 2, and

Inferred resources from Heruga. The 2018 PEA NPV8% is $278 million.

*Long term metal prices used in the net present value economic analysis are: copper US$3.00/lb, gold

US$1,300.00/oz and silver US$19.00/oz.

- 2 -

The economic analysis in the 2018 PEA does not have as high a level of certainty as the 2018 Reserve Case.

The 2018 PEA is preliminary in nature and includes Inferred mineral resources that are considered too

speculative geologically to have the economic considerations applied to them that would enable them to

be categorized as mineral reserves, and there is no certainty that the 2018 PEA will be realized. Mineral

resources are not mineral reserves and do not have demonstrated economic viability.

The Report was completed independently by Amec Foster Wheeler Americas Limited.

value and potential value of assets and the ability of Entrée to maximize returns to shareholders; potential types of mining operations; construction

and continued development of the Oyu Tolgoi underground mine; the expected timing of first development production from Lift 1 of the Entrée/Oyu

Tolgoi joint venture property; anticipated future production and mine life; the future prices of copper, gold, molybdenum and silver; the estimation

of mineral reserves and resources; the realization of mineral reserve and resource estimates; anticipated future production, capital and operating

costs, cash flows and mine life; anticipated business activities; and future financial performance.

In certain cases, forward-looking statements and information can be identified by the use of words such as "plans", "expects" or "does not expect",

"is expected", "budgeted", "scheduled", "estimates", "forecasts", "intends", "anticipates", or "does not anticipate" or "beli eves" or variations of

present and future business strategies, local and global economic conditions, legal proceedings and negotiations and t he environment in which

Entrée will operate in the future, including the price of copper, gold, silver and molybdenum, and the status of Entrée’s relationship and interaction

with the Government of Mongolia, O yu Tolgoi LLC (“O TLLC”), Rio Tinto and Turquois e 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

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; t he 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 Resources 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, silver and molybdenum

prices and demand; and production estimates and the anticipated yearly production of copper, gold , silver and molybdenum at the Oyu Tolgoi

underground mine. The 2018 PEA is based on a conceptual mine plan that includes Inferred resources. Numerous assumptions were made in the

preparation of the 2018 PEA, including with respect to mineability, capital and operating costs, production schedules, the timing of constru ction

and expansion of mining and processing facilities, and recoveries, that may change materially once production commences at H NE Lift 1 and

additional development and capital decisions are required. Any changes to the assumptions underlying the 2018 PEA could cause actual results to
