ENTRÉE RESOURCES WELCOMES ANNOUNCEMENTOF UPDATED FUNDING PLAN TO COMPLETE OYU TOLGOI UNDERGROUND CONSTRUCTION

Vancouver,B.C., April 9, 2021 – Entrée Resources Ltd. (TSX:ETG; OTCQB:ERLFF – the “Company” or “Entrée”) reports that on April 9, 2021, Turquoise Hill Resources Ltd. (“Turquoise Hill”), announced they have reached a binding agreement (“Heads of Agreement”) with Rio Tinto on a funding plan to complete the construction of Lift 1 of the Oyu Tolgoi underground project (“Oyu Tolgoi”) in Mongolia.

The Hugo North Extension deposit on the Entrée/Oyu Tolgoi JV Property is an integral part of the Lift 1 mine plan.

Stephen Scott, Entrée’s President & CEO commented, “This is great news for all Oyu Tolgoi project stakeholders, including Entrée. Ensuring remaining necessary capital funding is in place eliminates a key Oyu Tolgoi underground project execution risk. Achievement of this very important milestone moves the project one step closer to completion.”

Highlights of the Heads of Agreement include:

^1^ Theestimated remaining funding requirement is based on the terms of the Heads of Agreement and current anticipated copper prices, among otherfactors, and does not include funding, if any, which may become required for a power plant.

Oyu Tolgoi 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 joint venture property (“Entrée/Oyu Tolgoi JV Property”), which is a partnership between Entrée and OTLLC.
