Erdene Provides Notice to Buyback Sandstorm Gold’s Khundii Gold

Project Royalty

Halifax, Nova Scotia – March 26, 2019 - Erdene Resource Development Corp. (TSX:ERD ;

MSE:ERDN) ("Erdene" or the "Company") is pleased to announce its intention to repurchase a 1%

net smelter return royalty (“NSR”) from Sandstorm Gold Limited (“Sandstorm”) on its Khundii Gold

Project in southwest Mongolia by April 14, 2019 for C$1.2 million.

“Considering the results of our recent Preliminary Economic Assessment and the exploration potential

of the Khundii Gold Project licen se area, the fair value of the 1% NSR is well in excess of the

repurchase price. Buying back the NSR will create significant value for our shareholders ”, said Peter

Akerley, Erdene’s President and CEO . “We would like to acknowledge Sandstorm’s support during

the formative stages of the Khundii Gold Project and look forward to continuing to work with them as

we move toward production.”

As announced on April 21, 2016, Erdene completed a transaction granting Sandstorm a 2% NSR

royalty on a select area that include d the Khundii Gold Project as part of a C$2.5 million financing

transaction. This transaction provided Erdene with a three-year option to buy back 50% of the 2% NSR

Royalty for C$1.2 million. Erdene will fund the repurchase from cash on hand.

Review of Khundii Gold Project Development

Erdene’s deposits are located in the Edren Terrane, within the Central Asian Orogenic Belt, host to

some of the world’s largest gold and copper -gold deposits. The Company has been the leader in

exploration in southwest Mongolia over the past decade and is responsible for the discovery of the

Khundii Gold District comprised of multiple high-grade gold and gold/base metal prospects, two of

which are being considered for development: the 100%-owned Bayan Khundii and Altan Nar projects.

Together, these deposits comprise the Khundii Gold Project (the “Project”).

The Company delivered the Project’s maiden mineral resource estimate in Q3 2018 with a Measured

and Indicated (“M&I”) resource of 751,000 ounces (“oz”) gold at an average grade of 2.3 g/t gold and

an Inferred resource of 291,000 oz gold at an average grade of 1.8 g/t gold (cut-off grade of 0.7 g/t

gold). This was followed by a National Instrument 43-101 Standards of Disclosure for Mineral Projects

(“NI 43-101”) Preliminary Economic Assessment in December 2018 which returned an after-tax Net

Present Value at a 5% discount rate (“NPV5%”) and a US$1,200/oz gold price of US$99 million and

Internal Rate of Return (“IRR”) of 56%. The initial development has a life of mine head grade of 3.42

g/t gold with an average annual gold production of 51,200 oz over an eight-year mine life. Based on

the potential for additional discovery and expansion on the current licen se areas the planned

development is considered as a foundation for growth.
