ENTRÉE RESOURCES ANNOUNCES FIRST QUARTER 2024 RESULTS

Vancouver, B.C., May 8, 2024 – Entrée Resources Ltd. (TSX:ETG; OTCQB:ERLFF – the “ Company” or

“Entrée”) has today filed its interim financial results for the first quarter ended March 31, 2024. All

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

Q1 2024 HIGHLIGHTS

Oyu Tolgoi Underground Development Update

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

which is held by Oyu Tolgoi LLC (“OTLLC”) and the Entrée/Oyu Tolgoi JV Property, which is a joint venture

partnership between Entrée and OTLLC. Rio Tinto owns 66% of OTLLC and is the manager of operations

at Oyu Tolgoi.

 On April 17, 2024, Rio Tinto announced ramp up of the Oyu Tolgoi Lift 1 underground mine continues

in line with its long-term plan. Oyu Tolgoi is set to become the world’s fourth largest copper mine by

2030 with the operation expected to deliver average mined copper production of ~500 thousand

tonnes per annum between 2028 and 2036.

 OTLLC continues to see strong performance from the Lift 1 underground mine, with a total of 99 Lift

1 draw bells opened from Panel 0 on the Oyu Tolgoi mining licence, including 13 draw bells during the

quarter ended March 31, 2024. In the first quarter 2024, OTLLC delivered 1.3 million tonnes of ore

milled from Panel 0 on the Oyu Tolgoi mining licence at an average copper head grade of 1.67%.

 Shaft sinking continued during the first quarter 2024. At the end of March, Shafts 3 and 4 reached

1,076 metres and 1,150 metres below ground level, respectively. Final depths required for Shafts 3

and 4 are 1,130 metres and 1,176 metres below ground level, respectively. Shaft 4 breakthrough

(sinking completion) was achieved in early April. Rio Tinto continues to expect both shafts to be

commissioned in the second half 2024.

 As at March 31, 2024, construction of the conveyor to surface works was 94% complete.

Commissioning remains on track for the second half 2024.

 Construction works for the concentrator conversion remain on schedule. Commissioning is expected

to be progressively completed from the fourth quarter 2024 through to the second quarter 2025.

 Construction of primary crusher 2 commenced in December 2023 and is due to be completed by the

end of 2025.

 OTLLC’s 2023 Oyu Tolgoi Feasibility Study (“ OTFS23”) for the Lift 1 underground mine has been

submitted to and is under review by applicable regulatory bodies in Mongolia. The Lift 1 underground

- 2 -

mine incorporates the development of three panels (Panels 0, 1, and 2). The Hugo North Extension

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

 Drilling programs to support a Lift 2 Pre-Feasibility Study are in progress. Mineralization from Lift 2

will be included in an updated resource model for Hugo North (including Hugo North Extension).

Entrée/Oyu Tolgoi JV Property

 First Lift 1 Panel 1 development work on the Shivee Tolgoi mining licence is expected to commence in

the fourth quarter 2024. Development work will start in the southwest corner of the HNE deposit and

will establish the initial Panel 1 western ore handling truck chute, including extraction level tipple

development, the truck chute chamber on the haulage level, and the supporting ventilation loop with

the return air level. OTLLC has advised the Company all 2024 development will be in rock classified as

waste, which will be stockpiled separately and sampled in accordance with OTLLC’s standard sampling

protocols and procedures.

 Underground and surface in-fill diamond drilling at the Hugo North Extension deposit on the Shivee

Tolgoi mining licence is in progress. Approximately 14,128 metres of underground drilling in 25 holes

and 6,840 metres of surface drilling in 4 holes is planned for 2024. To date, approximately 4,475

metres of underground drilling in 13 holes and approximately 1,012 metres of surface drilling in 1 hole

has been completed. The principal purpose for the drilling is to support the Lift 2 Pre-Feasibility Study

and updated resource model for Hugo North (including Hugo North Extension).

 OTLLC is also proposing approximately 8,785 metres of diamond drilling in 5 surface holes on the

Heruga deposit (Javhlant mining licence) in 2024 to increase ore body knowledge and support an

Order of Magnitude Study. No drilling has been conducted on the Heruga deposit since 2008.

 The 2024 exploration program planned for the Shivee Tolgoi mining licence will focus on the Airstrip,

Ulaan Khud South and Ridge targets, including approximately 2,500 metres of diamond drilling in 2

inclined holes (one at Ulaan Khud South (~1,300 metres) and the other at the Ridge target (~1,200

metres), located midway between Ulaan Khud and Hugo North Extension) and geological and

geophysical studies. On the Javhlant mining licence, work will be conducted on the Bumbat Ulaan

target and the Heruga Trend (Heruga South and Heruga West targets). One diamond drill hole is

planned for each of the Heruga South (~1,300 metres) and Heruga West (~600 metres) targets as well

as geological and geophysical studies. At Bumbat Ulaan, approximately 1,200 metres of scout reverse

circulation drilling in 4 holes is planned.

Corporate

 For the Q1 2024 period, the Company’s operating loss was $1.1 million compared to $0.9 million in

Q1 2023. The increase was mainly due to legal costs for both commercial negotiations with OTLLC

and Rio Tinto and the arbitration proceedings.

 For the Q1 2024 period, the operating cash outflow before changes in non-cash working capital items

was $1.0 million compared to $0.7 million in Q1 2023.

 As at March 31, 2024, the cash balance was $5.1 million and the working capital balance was $4.9

million.

OUTLOOK AND STRATEGY

Entrée’s primary objective is to confirm the transfer of the Shivee Tolgoi and Javhlant mining licences from

the Company’s Mongolian subsidiary to OTLLC as contemplated by the joint venture agreement between

the Company and OTLLC (the “Entrée/Oyu Tolgoi JVA”), either in conjunction with finalization, execution,

and closing of an agreement with OTLLC to restructure or amend the existing Entrée/Oyu Tolgoi JVA to

streamline the operating environment for both parties, or enforcement of certain provisions of the 2004

Equity Participation and Earn-in Agreement and Entrée/Oyu Tolgoi JVA pursuant to binding arbitration

proceedings commenced by the Company in 2022. The Company currently is registered in Mongolia as

the 100% ultimate holder of the licences.

The commencement of arbitration proceedings followed protracted discussions with Rio Tinto and OTLLC

to confirm the transfer of the Shivee Tolgoi and Javhlant mining licences to OTLLC. The arbitration was

commenced in Vancouver, British Columbia under the International Commercial Arbitration Act (British

Columbia). A three-member Tribunal has been appointed and the first arbitration hearing took place in

Vancouver on April 8 and 9, 2024.

Notwithstanding the ongoing arbitration proceedings, the Company remains committed to achieving a

commercial resolution with Rio Tinto and OTLLC. Any definitive agreement reached between the Company

and OTLLC to restructure or amend the existing Entrée/Oyu Tolgoi JVA would be subject to Toronto Stock

Exchange acceptance and the requirements of Multilateral Instrument 61-101 – Protection of Minority

Security Holders in Special Transactions applicable to a related party transaction. There are no assurances

that a definitive agreement will be finalized and executed, or if finalized and executed, that the transaction

would close.

The Company has also been in discussions with Erdenes Oyu Tolgoi LLC (the State-owned company that

holds the Government’s 34% interest in OTLLC) regarding the potential for the Government of Mongolia

and Erdenes Oyu Tolgoi LLC to conclude an agreement with the Company for the State to share in 34% of

the economic benefit of the Company’s interest in the Entrée/Oyu Tolgoi JV Property. The Minerals Law

of Mongolia provides the State may share in up to 34% of the economic benefit derived from exploitation

of a mineral deposit of strategic importance where proven reserves were determined through funding

sources other than the State budget. The Hugo North Extension copper-gold deposit on the Shivee Tolgoi

mining licence and the Heruga copper-gold-molybdenum deposit on the Javhlant mining licence are

mineral deposits of strategic importance.

the first quarter ended March 31, 2024 are available on the Company’s website at
