Entrée Resources Ltd. Files NI 43-101 Technical Report for its Interest in the Entrée/Oyu Tolgoi Joint Venture Property

The Report discusses an updated Feasibility Study ("2021 Reserve Case") based on mineral reserves attributable to the Entrée/Oyu Tolgoi joint venture ("Entrée/Oyu Tolgoi JV") from the first lift ("Lift 1") of the Hugo North Extension copper-gold deposit. Lift 1 of Hugo North (including Hugo North Extension) is currently in development by project operator Rio Tinto as an underground block cave with first development production from Hugo North Extension expected in 2022. Entrée has a 20% or 30% participating interest (depending on the depth of mineralization) in the Entrée/Oyu Tolgoi JV with Oyu Tolgoi LLC ("OTLLC") holding the remaining 80% or 70% interest. The 2021 Reserve Case after-tax NPV(8%) for Hugo North Extension Lift 1 attributable to Entrée is US$114 million*.

The Report also includes a Preliminary Economic Assessment ("2021 PEA") on a conceptual second lift ("Lift 2") of the Hugo North Extension deposit. The 2021 PEA after-tax NPV(8%) for Hugo North Extension Lift 2 attributable to Entrée is US$306 million*. The 2021 PEA is based on Indicated and Inferred mineral resources from Lift 2 as the second potential phase of development and mining on the Hugo North Extension deposit. Production and cash flows from the 2021 Reserve Case and the 2021 PEA are from separate parts of the Hugo North Extension deposit and there is no overlap in the mineral reserves from the 2021 Reserve Case and the mineral resources from the 2021 PEA.

The Entrée/Oyu Tolgoi JV Property comprises a significant portion of the long-life, high-grade Oyu Tolgoi copper-gold mining project, as well as hosting several strong exploration prospects with the potential for near-surface porphyry and epithermal-style copper and/or gold mineralization. By 2030, Oyu Tolgoi is expected to be the fourth largest copper mine in the world.

*Long term metal prices used in the net present value economic analysis are: copper US$3.25/lb, gold US$1,591.00/oz and silver US$21.08/oz.

The economic analysis in the 2021 PEA is based on a conceptual mine plan and 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 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.

Both the 2021 Reserve Case and the 2021 PEA are based on information supplied by OTLLC or reported within OTLLC's 2020 Oyu Tolgoi Feasibility Study ("OTFS20"). Neither OTFS20 nor the results of the 2021 Reserve Case and 2021 PEA reflect the impacts of the COVID-19 pandemic, which are ongoing and continue to be assessed by OTLLC. Reference should be made to the full body of the Report for the assumptions, qualifications and procedures underlying the reported results, which are not fully described herein.

The Report was completed independently by Wood Canada Limited.

• The 2021 PEA is based on a conceptual mine plan that includes Inferred resources. Numerous assumptions were made in the preparation of the 2021 PEA, including with respect to mineability, capital and operating costs, production schedules, the timing of construction and expansion of mining and processing facilities, and recoveries, that may change materially once production commences at Hugo North Extension Lift 1 and additional development and capital decisions are required. Any changes to the assumptions underlying the 2021 PEA could cause actual results to be materially different from any future results, performance or achievements expressed or implied by forward-looking statements and information relating to the 2021 PEA.

Other risks, uncertainties and factors which could cause actual results, performance or achievements of Entrée to differ materially from future results, performance or achievements expressed or implied by forward-looking statements and information include, amongst others, unanticipated costs, expenses or liabilities; discrepancies between actual and estimated production, mineral reserves and resources and metallurgical recoveries; development plans for processing resources; matters relating to proposed exploration or expansion; mining operational and development risks, including geotechnical risks and ground conditions; regulatory restrictions (including environmental regulatory restrictions and liability); risks related to international operations, including legal and political risk in Mongolia; risks related to the potential impact of global or national health concerns, including the COVID-19 (coronavirus) pandemic; risks associated with changes in the attitudes of governments to foreign investment; risks associated with the conduct of joint ventures; inability to upgrade Inferred mineral resources to Indicated or Measured mineral resources; inability to convert mineral resources to mineral reserves; conclusions of economic evaluations; fluctuations in commodity prices and demand; changing foreign exchange rates; the speculative nature of mineral exploration; the global economic climate; dilution; share price volatility; activities, actions or assessments by Rio Tinto, Turquoise Hill Resources Ltd. or OTLLC and by government authorities including the Government of Mongolia; the availability of funding on reasonable terms; the impact of changes in interpretation to or changes in enforcement of laws, regulations and government practices, including laws, regulations and government practices with respect to mining, foreign investment, royalties and taxation; the terms and timing of obtaining necessary environmental and other government approvals, consents and permits; the availability and cost of necessary items such as water, skilled labor, transportation and appropriate smelting and refining arrangements; unanticipated reclamation expenses; changes to assumptions as to the availability of electrical power, and the power rates used in operating cost estimates and financial analyses; changes to assumptions as to salvage values; ability to maintain the social license to operate; accidents, labor disputes and other risks of the mining industry; global climate change; title disputes; limitations on insurance coverage; competition; loss of key employees; cyber security incidents; misjudgments in the course of preparing forward-looking statements; and those factors discussed in the section entitled "Critical Accounting Estimates, Risks and Uncertainties" in the Company's most recently filed Management's Discussion & Analysis and in the section entitled "Risk Factors" in the Company's Annual Information Form for the year ended December 31, 2020 filed with the Canadian Securities Administrators and available at www.sedar.com. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended.
