Exhibit 99.1

Entrée Resources Announces Fiscal Year 2020 Results and Reviews Corporate Highlights

VANCOUVER, BC, March 31, 2021 /CNW/ - 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, 2020. All numbers are in U.S. dollars unless otherwise noted.

2020 HIGHLIGHTSOyu Tolgoi Underground DevelopmentThe Oyu Tolgoi project in Mongolia includes two separate land holdings: the Oyu Tolgoi mining licence, which is held by Entrée's joint venture partner Oyu Tolgoi LLC ("OTLLC") and the Entrée/Oyu Tolgoi joint venture property (the "Entrée/OyuTolgoi JV Property"), which is a partnership between Entrée and OTLLC. On March 8, 2021, OTLLC's 66% shareholder Turquoise Hill Resources Ltd. ("Turquoise Hill") provided an update on underground development on the Oyu Tolgoi mining licence:

• Work on the Oyu Tolgoi underground project has continued to materially progress in line with the Definitive Estimate (as defined below) despite COVID-19 controls and ongoing travel restrictions implemented by the Government of Mongolia. Ongoing impacts to domestic and international movement could have an impact on key project milestones on the Oyu Tolgoi mining licence.
• Overall, underground lateral development has now reached 53,000 equivalent metres with development required before first drawbell on the Oyu Tolgoi mining licence substantially complete. More than one million tonnes of underground material has moved through Shaft 2 since commissioning and scheduled annual maintenance of Shaft 2 was successfully completed in October 2020 using remote technology. Materials Handling System 1 progress continues with civil work complete on Primary Crusher 1 and steel and cable installation continuing thereon.
• Remobilization of international shaft-sinking specialists occurred in the fourth quarter 2020. Installation and commissioning of sinking related equipment continues at Shafts 3 and 4. Activities at Shaft 4 in the fourth quarter 2020 were focused on completing all construction and commissioning activities for load testing and verification in preparation for shaft sinking, which commenced in early February

2021. Shafts 3 and 4 will provide ventilation to support the ongoing development associated with production ramp up for Panels 1 and 2. Should flight restrictions continue, productivity on the project and the ability to perform specialized maintenance and commissioning activities could be impacted. Turquoise Hill continues to assess any potential implications, particularly for Panel 1 and Panel 2 ramp-up which Shafts 3 and 4 support.

• In the first quarter 2020, OTLLC submitted a resources and reserves update for registration pursuant to local regulatory requirements in Mongolia. On July 2, 2020, Turquoise Hill announced the completion of an updated Oyu Tolgoi Feasibility Study ("OTFS20"), which incorporates the new block cave mine design for Hugo North Lift 1 Panel 0 previously announced by Turquoise Hill on May 13, 2020. The expert review of the resources and reserves update is in progress and OTFS20 is expected to be considered for endorsement by the Mongolian regulators following registration.
• OTFS20 incorporates an update to the first sustainable production schedule and capital cost estimates for the underground mine development based on the new Panel 0 mine design. On December 18, 2020, Turquoise Hill announced the completion and delivery by Rio Tinto of the definitive estimate of cost and schedule (the "Definitive Estimate"), which refines the analysis contained in OTFS20. The results of the Definitive Estimate include a revised base case development capital cost of $6.75 billion for the new design, confirmation that sustainable first production from the Oyu Tolgoi mining licence is forecast to occur in October 2022, and verification that all surface infrastructure required for sustainable first production from Panel 0 on the Oyu Tolgoi mining licence is now complete. Additional project infrastructure will still be needed to support the production ramp-up profile and the life of mine material handling infrastructure capacity. The Definitive Estimate also finalized pillar locations on the Panel 0 boundaries and optimized the drawpoint layout to minimize exposure to the lower fault. OTLLC board approval of the Definitive Estimate will be considered following registration of the resources and reserves update and endorsement of OTFS20.
• The Hugo North (including Hugo North Extension) 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 from the underground operations, all three panels need to be in production. The Hugo North Extension deposit on the Entrée/Oyu Tolgoi JV Property is located at the northern portion of Panel 1.
• Turquoise Hill has advised that several mining studies are in progress, which are focused on the evaluation of different design and sequencing options for Panels 1 and 2 as part of OTLLC's planned Pre-Feasibility and Feasibility Study level work. These studies are underpinned by additional geology and geotechnical data that is being collected from underground and surface drilling. The data collection is complete for Panel 0 and the focus of data collection and analysis has now shifted to Panel 1 and Panel 2. Data collection and analysis is being prioritized to complete study work in line with mining progression

Corporate

• During Q3 2020, the Company closed a non-brokered private placement of 10,278,000 units of the Company at a price of C$0.43 per unit for gross proceeds of approximately C$4.4 million. Each unit consists of one common share and one-half of one transferable common share purchase warrant (each whole warrant, a "Warrant"). Each Warrant entitles the holder to purchase one additional common share of the Company at a price of C$0.60 per share for a period of three years following the date of issuance.
• For the full 2020 year, the operating loss was $2.3 million compared to an operating loss of $2.1 million in 2019.
• For the full 2020 year, operating cash outflow before working capital was $1.5 million compared to an operating cash outflow before working capital of $1.5 million in 2019.
• As at December 31, 2020, cash was $7.3 million and the working capital balance was $7.3 million.
• 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 STRATEGYThe Company's primary objective for the 2021 year is to work with other Oyu Tolgoi stakeholders 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 underground 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.

In addition, the Company is currently in the process of reviewing the data and assumptions underlying OTFS20, the OTFS20 block cave designs, updated costs and schedules and the updated mineral resources and reserves in order to assess the potential impact on the Entrée/Oyu Tolgoi JV Property resources and reserves and the assumptions and outputs from the Company's 2018 Technical Report. The Company will update the market following completion of its review and assessment.

SUMMARY OF OPERATING RESULTSOperating LossFor the full 2020 year, the operating loss was $2.3 million compared to an operating loss of $2.1 million in 2019.  Project expenditures in 2020 included expenditures of $0.2 million for administration costs in Mongolia compared to $0.2 million in the comparative 2019 period.  Holding costs on all other properties in 2020 and 2019 were insignificant.

General and administration expenditures in 2020 were $1.4 million and were consistent with the same period in 2019.

Depreciation expenses in 2020 were consistent with the same period in 2019.

Non-operating ItemsThe foreign exchange gain in 2020 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, 2020 were higher than at December 31, 2019 due to funds received from the non-brokered private placement completed during Q3 2020 while total non-current liabilities were higher due to recording the non-cash deferred revenue finance costs for the 2020 year.
