Entrée Resources Welcomes Completion of 2020 Oyu Tolgoi Feasibility Study

ENTRÉE RESOURCES WELCOMES COMPLETION OF

2020 OYU TOLGOI FEASIBILITY STUDY

Vancouver, B.C., July 6, 2020 – Entrée Resources Ltd. (TSX: ETG; OTCQB: ERLFF – the “Company” or

“Entrée”) reports that on July 2, 2020, Turquoise Hill Resources Ltd. (“ Turquoise Hill ”) announced the

completion of an updated Oyu Tolgoi Feasibility Study (“OTFS20”) that incorporates the new mine design

for Hugo North Lift 1 Panel 0. The Company’s joint venture partner Oyu Tolgoi LLC (“ OTLLC”) is in the

process of submitting OTFS20 with the Government of Mongolia in order to comply with local regulatory

requirements.

Stephen Scott, Entrée’s President & CEO commented, “We look forward to reviewing OTFS20 and to

completion of the previously announced defini tive estimate review and Panel 1 design optimization

studies by OTLLC, Turquoise Hill and Rio Tinto. While Turquoise Hill has reported a reduction in its mineral

reserve estimate for the overall Hugo North underground mine due to the inclusion of two struc tural

pillars, it is encouraging to see that the ore tonnes and contained copper, gold and silver for the Probable

mineral reserve that Turquoise Hill reported for the Entrée/Oyu Tolgoi joint venture property ha ve all

increased. In addition, we are excited to hear that drilling is underway at Panel 1 and look forward to

seeing the results. We are pleased with our partners’ efforts to remain within the guidance ranges on

cost and schedule previously announced by Turquoise Hill and believe that the steps that our partners are

taking to optimize the mine plan for Panels 1 and 2 will be of great benefit to all stakeholders, including

Entrée.”

In its July 2, 2020 news release, Turquoise Hill noted the Hugo North (including Hugo North Extension) Lift

1 mine plan incorporates the development of three panels and in order to reach the full sustainable

production rate of 95,000 tonnes per day from the underground operations, all three panels need to be

in production. The Hugo North Extension deposit on the Entrée/Oyu Tolgoi joint venture property

(“Entrée/Oyu Tolgoi JV Property”) is located at the northern portion of Panel 1.

According to Turquoise Hill, the block cave design incorporated in OTFS20 provides for 120 metre

structural pillars included to the north and south of Panel 0, protecting ore handling infrastructure (which

will be moved into the structural pillars) and increasing the optionality of sequencing Panel 1 and Panel 2.

The structural pillars are planned to be located on the Oyu Tolgoi mining licence. Turquoise Hill believes

the existing feasibility study designs for Panel 1 and Panel 2 remain executable based on the current

orebody understand ing. However, with the introduction of structural pillars, Panels 1 and 2 become

independent, allowing for much greater operational flexibility. According to Turquoise Hill t his provides

opportunities to:

• Optimise the extraction level elevation for each panel independently;

• Evaluate the potential to convert Measured and Indicated mineral resources below the current

Lift 1 extraction level to Probable mineral reserves;

- 2 -

• Complete additional confirmatory drilling and data collection in support of potential Panel 1 and

Panel 2 design refinements; and

• Include structural pillar recovery level(s) in the integrated Hugo North Lift 1 mine design.

Turquoise Hill noted that Panel 1 and Panel 2 design optimization studies have been initiated to explore

these opportunities. The studies are not expected to delay the ramp up of Panel 1 or Panel 2 . Drilling

work is underway and the resulting updates to geotechnical modelling and mine design review are

expected by Turquoise Hill to continue into 2021.

Turquoise H ill also announced its updated Mineral Resources and Mineral Reserves prepared in

accordance with the requirements of National Instrument 43 -101 – Standards of Disclosure for Mineral

Projects (“NI 43-101”) and CIM definition standards for Mineral Resources and Mineral Reserves (2014) .

Turquoise Hill noted that OTFS20 does not reflect the impacts of the COVID -19 pandemic , which are

ongoing and continue to be assessed. A number of work fronts are directly impacted including Shafts 3

and 4 being put on care and maintenance and work on Primary crusher 1 being slowed due to the lack of

availability of critical resources and restrictions on site workforce numbers.

Entrée’s 2018 Technical Report completed on its interest in the Entrée/Oyu Tolgoi JV Property discusses

two development scenarios , a reserve case (the “2018 Reserve Case ”) and a Life -of-Mine Preliminary

Economic Assessment ( the “2018 PEA ”). The 2018 Reserve Case is based only on mineral reserves

attributable to the Entrée/Oyu Tolgoi JV from Lift 1 of the Hugo North Extension underground block cave.

Both the 2018 Reserve Case and the 2018 PEA are based on information reported within the 2016 Oyu

Tolgoi Feasibility Study (“OTFS16”).

Rio Tinto is managing the construction and eventual operation of Lift 1 as well as any future development

of deposits included in the 2018 PEA. In 2019, s ubsequent to the completion of OTFS16 and the 2018

Technical Report, Rio Tinto advised that more detailed geotechnical information and different ground

conditions have required a review of the mine design and the development schedule reflected in OTFS16

and the 2018 Technical Repor t. Once the definitive estimate of cost and schedule and the Panel 1

optimization studies have been completed and delivered to Entrée with OTFS20, the Company will be able

to assess the potential impact on Entrée/Oyu Tolgoi JV Property production and financial assumptions

and outputs from the two alternative cases, the 2018 Reserve Case and the 2018 PEA.

Readers are cautioned that the Company has not yet been provided with OTFS20 or any of the data or

assumptions underlying OTFS20, the block cave designs in OTFS20 or Turquoise Hill’s upd ated Mineral

Resources and Reserves and the Company is therefore unable to verify such data or the scientific and

technical disclosures made by Turquoise Hill at this time. For information on the Company’s interest in

Entrée/Oyu Tolgoi JV Property, see the Company’s current Technical Report, titled “Entrée/Oyu Tolgoi

Joint Venture Project, Mongolia, NI 43-101 Technical Report”, with an effective date of January 15, 2018,

Robert Cinits, P.Geo., consultant to Entrée and the Company’s former Vice President, Corporate

Development, and a Qualified Person as defined by National Instrument 43-101 – Standards of Disclosure
