ENTRÉE RESOURCES PROVIDES UPDATE ON ENTRÉE/OYU TOLGOI JV AND

UPCOMING NI 43-101 TECHNICAL REPORT

Vancouver, B.C., October 18, 2017 – Entrée Resources Ltd. (TSX:ETG; NYSE American:EGI – the

“Company” or “Entrée”) is pleased to announce that Amec Foster Wheeler Americas Limited (“Amec

Foster Wheeler”) has completed its initial data review, and has commenced work on an updated National

Instrument 43 -101 Technical Report (the “Technical Report”) relating to Entrée’s 20% participating

interest in the Entrée/Oyu Tolgoi joint venture (“Entrée/Oyu Tolgoi JV”) in Mongolia.

The updated Technical Report will include:

• an updated reserve case for the first lift (“Lift 1”) of the Hugo North Extension block cave on the

Entrée/Oyu Tolgoi JV property. The reserve will be based on information contained within the

2016 Oyu Tolgoi Feasibility Study finalized in May 2016 by Entrée’s joint venture part ner Oyu

Tolgoi LLC (“OTLLC”). First development production from Lift 1 on the Entrée/Oyu Tolgoi JV

property is expected in approximately 2021; and

• a Preliminary Economic Assessment of Entrée’s interest in both Lift 2 of the Hugo North Extension

copper-gold deposit (“Lift 2”) and the Heruga copper-gold-molybdenum deposit (“Heruga”).

The Technical Report is expected to be completed by January 2018.

Stephen Scott, Entrée’s President and CEO comments, “We are very excited work has commenced on the

updated Technical Report, which will be a significant milestone for the Company and help investors

understand the tremendous underlying value of Entrée’s fla gship asset . Completion of the Technical

Report will enable us to discuss preliminary economics for potential future phases of the Oyu Tolgoi mine,

beyond Lift 1 , including Lift 2 and Heruga, where a significant amount of the Entrée/Oyu Tolgoi JV’s

mineralization occurs.”

Oyu Tolgoi Underground Project Update

Entrée management and representatives from Amec Foster Wheeler recently visited the Oyu Tolgoi

underground development project and supporting infrastructure in Mongolia. Based on the visit and

recent disclosure by Turquoise Hill Resources, Entrée is pleased to confirm that the development of Shaft

4, which will be the first physical development work on the Entrée /Oyu Tolgoi JV property, is scheduled

to commence in 2018. S haft 4 will provide the necessary ventilation required to support mining of the

northern part of the Hugo North deposit (including Hugo North Extension on the Entrée/Oyu Tolgoi JV

property), which is reported to contain some of the highest-grade copper-gold mineralization in the entire

Oyu Tolgoi project. Completion of Shaft 4 is expected in 2021, with first development production from

Hugo North Extension Lift 1 also expected in 2021.

The site visit, led by s enior OTLLC team members, provided Entrée management with an opportunity to

tour some of the main surface infrastructure, including the concentrator and tailings facilities and to also

go underground to observe some of the development work completed to date . In addition, Entrée

management was able to review plans with OTLLC for the immediate and medium-term future. Entrée is

pleased to report that project development, including both direct production and supporting

infrastructure, appears to be on track and is being completed to the highest safety and operating

standards.

Mr. Scott continues, “The commencement of physical work on the Entrée/Oyu Tolgoi JV property in 2018

is the second important milestone and will bring the Company one step closer to becoming a producing

mining company in just three years, a timeframe coincident with market expectations of global copper

supply moving towards a deficit position. The resources case in Turquoise Hill’s most recent technical

report on the Oyu Tolgoi project filed in October 2016 indicates an es timated mine life in excess of 95

years based on current estimated resources and throughput rates. In the context of world class mining

projects such as Oyu Tolgoi, which often take several decades from initial discovery to first production,

the time between now and first development production on the Entrée/Oyu Tolgoi JV property in 2021 is

extremely short.”

Additional near-term milestones for the project include the commissioning of Shaft 2, completion of the

Oyut II Camp, commencement of work on Shafts 3 and 4, and completion of Shaft 5.

Robert Cinits, P.Geo., Entrée's Vice President, Corporate Development, a Qualified Person as defined by
