ENTRÉE RESOURCES ANNOUNCES FISCAL YEAR 2021 RESULTS and REVIEWS

CORPORATE HIGHLIGHTS

Vancouver, B.C., March 25, 2022 – Entrée Resources Ltd. (TSX:ETG; OTCQB:ERLFF – the “ Company” or

“Entrée”) has today filed its annual operational and financial results for the year ended December 31,

2021. All numbers are in U.S. dollars unless otherwise noted.

2021 HIGHLIGHTS

Entrée/Oyu Tolgoi JV Property

On October 21, 2021, Entrée filed an amended Technical Report (the “ 2021 Technical Report ”) for its

interest in the Entrée/Oyu Tolgoi joint venture property in Mongolia (the “ Entrée/Oyu Tolgoi JV

Property”). The 2021 Technical Report has an original effective date of May 17, 2021, and an amended

effective date of October 8, 2021.

x The 2021 Technical Report discusses an updated reserve case (the “ 2021 Reserve Case”) based

on mineral reserves attributable to the Entrée/Oyu Tolgoi joint venture (the “Entrée/Oyu Tolgoi

JV”) from the first lift (“Lift 1”) of the Hugo North Extension deposit and a Preliminary Economic

Assessment on a conceptual second lift (“ Lift 2”) of the Hugo North Extension deposit (“ 2021

PEA”).

x Life-of-mine (“LOM”) financial highlights attributable to Entrée from the 2021 Reserve Case and

the 2021 PEA include:

Notes:

1. Long term metal prices used in the net present value (“ NPV”) economic analyses are: copper $3.25/lb, gold $1,591.00/oz and silver

$21.08/oz.

2. The mineral reserves that form the basis of the 2021 Reserve Case are from a separate portion of the Hugo North Extension dep os it

than the mineral resources in the 2021 PEA. The 2021 Reserve Case and the 2021 PEA are therefore exclusive of each other.

3. The economic analysis in the 2021 PEA does not have as high a level of certainty as the 2021 Reserve Case. The 2021 PEA is preliminary

in nature and includes Inferred mineral resources that are considered too speculative geologically to have the economic

- 2 -

considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the 2021

PEA will be realized. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

4. 2021 Reserve Case cash flows are discounted to the beginning of 2021.

5. 2021 PEA cash flows are discounted to the beginning of 2027, the assumed beginning of Hugo North Lift 2 development. Attributable

Entrée/Oyu Tolgoi JV production is assumed to begin in 2031 and ramps up to stable production in 2043. Final Entrée/Oyu Tolgoi JV

attributable production is assumed to conclude in 2056.

6. Entrée has a 20% attributable interest in the recovered metal.

7. 2021 Reserve Case mine life includes 4-years development production followed by 13-years block cave production. 2021 PEA mine

life includes 4-years development production followed by 18-years block cave production.

x Both the 2021 Reserve Case and the 2021 PEA are based on information supplied by Entrée’s joint

venture partner Oyu Tolgoi LLC (“ OTLLC”) or reported within the 2020 Oyu Tolgoi Mongolian

Statutory Study (previously referred to as the 2020 Oyu Tolgoi Feasibility Study) (“ OTMSS20”),

which was completed by OTLLC on the Oyu Tolgoi project in July 2020 (refer to the July 2, 2020

press release from Turquoise Hill Resources Ltd. (“Turquoise Hill”)). OTMSS20 discusses the mine

plan for Lift 1 of the Hugo North (including Hugo North Extension) underground block cave on

both the Oyu Tolgoi mining licence and the Entrée/Oyu Tolgoi JV Property. The 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 (“ tpd”) from the underground operations, all three

panels need to be in production. Hugo North Extension on the Entrée/Oyu Tolgoi JV Property is

located in the northern portion of Panel 1.

x The Lift 1 mine design presented in OTMSS20 and the 2021 Reserve Case is subject to future

refinements and updates. Hugo North (including Hugo North Extension) Lift 1 surface and

underground drilling programs will support the ev aluation by OTLLC of different design and

sequencing options for Panels 1 and 2. As reported by Turquoise Hill, during 2021 a total of 10,494

metres of Panel 1 drilling was undertaken to increase orebody knowledge. The data collected has

been used to refine the structural and geotechni cal models which form the basis of the mine

design. From 2022 onwards, the focus of dri lling will shift to Lift 2 and peripheral areas of Lift 1.

In 2021, 1,009 metres of Lift 2 Panel 1 drilling was completed. The Panel 1 study is scheduled for

completion in the first half of 2023. Entrée has not yet received any details or results of OTLLC’s

surface and underground drilling programs from 2021.

x The 2021 Technical Report assumes first development production from Hugo North Extension Lift

1 in H2 2022. Turquoise H ill has reported that Panels 1 and 2 are expected to be delayed as a

result of the delay in commencement of the Panel 0 undercut, COVID-19 related work restrictions

impacting progress on Shafts 3 and 4 and underground development, and changes to mining

scope. Turquoise Hill has reported that efforts to minimize delays to Panels 1 and 2 due to

ventilation constraints ahead of Shaft 3 and 4 commissioning continue. Shafts 3 and 4 are required

to provide ventilation to support production from Panels 1 and 2 during ramp up to 95,000 tpd.

An approximately 9-month delay to Shafts 3 and 4 is currently anticipated with the first Panel 1

draw bell now expected by Turquoise Hill in H1 2027 rather than H2 2026.

x Turquoise Hill reported that a reforecast of cost and schedule for the remaining Lift 1 underground

project scope is now expected in the second quarter 2022. The Company continues to monitor

the situation in Mongolia including with respect to possible delays to commencement of Panel 1.

The Company will assess the potential impact of any delays as it becomes aware of them and will

update the market accordingly.

Oyu Tolgoi Underground Development

The Oyu Tolgoi project in Mongolia includes two separate land holdings: the Oyu Tolgoi mining licence,

which is held by Entrée’s joint venture partner OTLLC and the Entrée/Oyu Tolgoi JV Property, which is a

partnership between Entrée and OTLLC. On March 2, 2022, OTLLC’s 66% shareholder Turquoise Hill

provided an update on Oyu Tolgoi underground development:

x COVID-19 impacts in Mongolia are ongoing. During the fourth quarter 2021, COVID-19 restrictions

adversely impacted underground development and OTLLC’s ability to maintain normal roster

changes for workers remained challenged.

x OTLLC continues to implement multiple COVID-19 controls at site and maintains a 5-day

mandatory isolation for workers prior to entering site. With the arrival of the Omicron variant of

COVID-19, cases increased at site during early 2022, however shorter quarantine periods have

been maintained and cases are being managed well. Some interruption to work progress is

expected in the first quarter 2022.

x Although COVID-19 related restrictions continued to impact Shaft 3 and 4 activities, progress was

made during the fourth quarter 2021. Shaft 4 sinking activities re-commenced in October 2021,

with advancement now at 148 metres below gr ound level. Shaft 3 readiness works continued,

with sinking commencement expected by the end of the first quarter 2022. In response to slower

than planned sinking rates at Shaft 4, a pro ductivity improvement program is underway and

outcomes will be applied to activities in both shafts.

x The underground project progressed well during the fourth quarter 2021 with breakthrough of

the service decline achieved and caving related development and construction continuing.

Material Handling System 1 (“ MHS1”) construction was completed in the fourth quarter 2021.

MHS1 commissioning and construction of the first on-footprint truck chute, a key enabler for

production, was achieved in February 2022, and sustainable production from Lift 1 Panel 0 is still

expected in H1 2023.

x Ahead of the first Lift 1 Panel 0 drawbell blast, expected in the third quarter 2022, development

and construction work on the extraction level continues with drawbell drives in the initiation area

being excavated, drawpoint construction underway and concrete roadways laid, as well as

continued construction work on truck chutes supporting Panel 0.

x At the end of the fourth quarter 2021, cumulative underground development progress was 63,418

equivalent metres (“eqm”) and cumulative conveyor to surface advancement was 15,862 eqm.

x On January 24, 2022, Turquoise H ill announced the resolution of key outstanding issues related

to the Oyu Tolgoi underground mine:

o Turquoise Hill and the Government of Mongolia reached a mutual understanding for a

renewed partnership.

o Turquoise Hill and Rio Tinto entered into a binding agreement that delineates a

comprehensive funding arrangement to address Turquoise Hill’s estimated incremental

funding requirements to complete the project (the “Amended HoA”).

- 4 -

o The OTLLC board approved the signing of an Electricity Supply Agreement to provide Oyu

Tolgoi with a long-term source of power fr om the Mongolian grid on terms fully agreed

with the Government of Mongolia.

x Following progress in negotiations with the Go vernment of Mongolia, all undercut readiness

criteria were considered to be achieved on January 24, 2022 with the OTLLC board having

unanimously approved commencement of the undercut.

x On March 14, 2022, Rio Tinto announced it has made a non-binding proposal to Turquoise Hill to

acquire the approximately 49% of the issued and ou tstanding shares of Turquoise Hill that Rio

Tinto does not currently own for approximately $2.7 billion. In addition to strengthening Rio

Tinto’s copper portfolio, the acquisition would create a more efficient ownership and governance

structure for the Oyu Tolgoi project. Following the successful completion of a transaction, Rio

Tinto would have a 66% interest in deposits on the Oyu Tolgoi mining licence and a 52.8% interest

in the Hugo North Extension and Heruga deposits on the Entrée/Oyu Tolgoi JV Property.

Corporate

x For the 2021 fiscal year, the operating loss was $3.0 million compared to an operating loss of $2.3

million in 2020.

x For the 2021 fiscal year, operating cash outflow before working capital was $2.1 million compared

to an operating cash outflow before working capital of $1.5 million in 2020.

x As at December 31, 2021, the cash balance was $7.1 million and the working capital balance was

$7.2 million.

x The Company recognizes the unprecedented situation surrounding the ongoing COVID-19

pandemic and is closely monitoring the effect of the COVID-19 pandemic on its business and

operations and will continue to update the market on the impacts to the Company’s business and

operations in relation to these extraordinary circumstances.

OUTLOOK AND STRATEGY

With the commencement of the Lift 1 Panel 0 undercut, Turquoise Hill’s renewed partnership with the

Government of Mongolia and execution of a comprehen sive funding plan for the world class Oyu Tolgoi

underground mine, Entrée’s primary objective for the 2022 year is to advance potential amendments to

the joint venture agreement (the “ Entrée/Oyu Tolgoi JVA ”) that currently governs the relationship

between Entrée and OTLLC and upon finalization, transfer the Shivee Tolgoi and Javhlant mining licences

to OTLLC as manager of the Entrée/Oyu Tolgoi joint venture (the “ Entrée/Oyu Tolgoi JV”). The form of

Entrée/Oyu Tolgoi JVA was agreed between the parties in 2004, prior to the execution of the Oyu Tolgoi

Investment Agreement and commencement of und erground development. The Company currently is

registered in Mongolia as the 100% ultimate holder of the Shivee Tolgoi and Javhlant mining licences.

The Company believes that amendments that align the interests of all stakeholders as they are now

understood would be in the best interests of all stakeholders, provided there is no net erosion of value to

Entrée. No agreements have been finalized and there are no assurances agreements may be finalized in

the future.

SUMMARY OF OPERATING RESULTS

Operating Loss

For the full 2021 year, the operating loss was $3.0 million compared to an operating loss of $2.3 million

in 2020. Project expenditures in 2021 included expenditures of $0.5 million for administration costs in

Mongolia compared to $0.2 million in the comparative 2020 period. The increase in the current year was

due to professional and advisory fees related to advancing potential amendments to the Entrée/Oyu

Tolgoi JVA. Holding costs on all other properties in 2021 and 2020 were insignificant.

General and administration expenditures in 2021 was $1.6 million compared to $1.4 million in the

comparative 2020 period. The increase in 2021 was du e to increased advisory costs related to potential

amendments to the Entrée/Oyu Tolgoi JVA.

Depreciation expenses in 2021 were consistent with the same period in 2020.

Non-operating Items

The foreign exchange gain in 2021 was primarily the result of movements between the C$ and U.S. dollar

as the Company holds its cash in both currencies and the loan payable is denominated in U.S. dollars.

Interest expense was primarily related to the loan payable to OTLLC pursuant to the Entrée/Oyu Tolgoi

JVA and is subject to a variable interest rate.

The amount recognized as a loss from equity investee is related to exploration costs on the Entrée/Oyu

Tolgoi JV Property.

Deferred revenue finance costs are related to recording the non-cash finance costs associated with the

deferred revenue balance, specifically the Sandstorm Gold Ltd. stream.

The total assets as at December 31, 2021 were lowe r than at December 31, 2020 due to a lower cash

balance from operating activities. Total non-current liabilities were higher due to recording the non-cash

deferred revenue finance costs for the 2021 year.
