High-Grade Drill Results at Hugo North Extension Follow Commencement of Development Work

Entrée Resources Ltd. ("Entrée") has announced advancements at the Oyu Tolgoi Hugo North Extension ("HNE"). In November 2024, underground development work commenced at Oyu Tolgoi Lift 1 Panel 1, part of the Entrée/Oyu Tolgoi joint venture property, focusing on up to 212 metres of lateral development in the southwest corner of HNE. This work, outlined in the 2024 Oyu Tolgoi Mine Plan, is a critical step in preparing the infrastructure for future mining operations. Concurrently, Entrée continues discussions with Rio Tinto and Oyu Tolgoi LLC ("OTLLC") to finalize governance agreements for the joint venture, exploring both the execution and delivery of the existing JV agreement or a new arrangement with equivalent economic value. Entrée indicated that a clear pathway forward has been identified, with final agreements requiring OTLLC board approval.

In addition, results from eight remaining diamond drill holes from the 2023 drilling program at HNE have been released, confirming high-grade mineralization within the Hugo North Lift 2 block cave footprint and extending the deposit's potential at depth. Notably, surface drill hole EGD 174 intersected 448 metres grading 1.31% copper including 172 metres at 1.58% copper. The hole terminated in mineralization at a depth of 1,800 metres, indicating the deposit remains open at depth for deeper potential lifts. Additional surface drilling included EGD 177, which intersected 143 metres grading 1.09% copper, including 51 metres at 1.75% copper. At depths, the Hugo North deposit dips to the northwest with an increasing proportion located on the Entrée/Oyu Tolgoi joint venture ground. Underground geotechnical drilling further confirmed the continuity of mineralization, with high-grade results such as UGD 805B intersecting 177.3 metres at 1.79% copper, UGD 813 intersecting 56 metres at 1.45% copper, and UGD 814 intersecting 138 metres at 1.92% copper.

Drilling activities in 2024 have concentrated on the Hugo North Lift 2 mineralized footprint. As of October 31, OTLLC had completed 5,287 metres of underground drilling across 23 diamond drill holes and 2,476 metres of surface drilling across four diamond drill holes. These efforts continue to enhance understanding of the resource, and Entrée expects to share further updates once the results have been reviewed.

These developments continue to highlight the high-grade nature of HNE and the significant potential of the deposit.

RISK FACTORS REGARDING ENTRÉE/OYU TOLGOI JOINT VENTURE AGREEMENT

Entrée Resources Ltd ("Entrée") previously disclosed in 2022 that, with Lift 1 Panel 0 underground development work progressing, Entrée's ability to effect transfer of the mining licenses and achieve contractual certainty through negotiation remains uncertain, and Entrée may be unable to advance discussions with the Government of Mongolia in a meaningful way without first confirming its underlying contractual rights and obligations vis-à-vis OTLLC. Entrée's board of directors authorized and approved the commencement of binding arbitration proceedings to seek declarations and orders for specific performance relating to certain provisions of the Earn-in Agreement and the Entrée/Oyu Tolgoi Joint Venture Agreement. The arbitration was commenced on May 26, 2022 in Vancouver, British Columbia under the International Commercial Arbitration Act (British Columbia). A three-member Tribunal was appointed and the evidentiary hearing took place in Vancouver on April 8 and 9, 2024. Closing submissions were heard in Toronto on July 10, 2024. To date, no decision has been released and Entrée does not know when a decision will be forthcoming. Further, Entrée does not know if the Tribunal will release a partial or final decision. If a partial decision is released further submissions and hearings may be necessary. There can be no assurance that a decision will be favourable to Entrée. While Entrée remains committed to achieving a commercial resolution with Rio Tinto and OTLLC, if an arbitration decision is received prior to the execution of any definitive alternative agreement(s), there can be no assurance as to whether both parties would continue to try to progress a commercial resolution as currently contemplated or at all. Furthermore, in the third quarter of 2024 Entrée met with Mongolian officials to reaffirm Entrée's commitment to fulfil any obligation it has under applicable Mongolian law to share with the State of Mongolia up to 34% of the economic benefit derived by Entrée from its 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 (a "Strategic Deposit") 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 license and the Heruga copper-gold-molybdenum deposit on the Javhlant mining licence are part of the Oyu Tolgoi group deposits. The Oyu Tolgoi group deposits were classified a Strategic Deposit by Resolution No. 27 dated February 6, 2007, adopted by the Parliament of Mongolia.
