Erdene Completes Repurchase of Sandstorm Gold’s Khundii Gold Project Royalty

HALIFAX, April 16, 2019 - Erdene Resource Development Corp. (TSX:ERD; MSE:ERDN) ("Erdene" or the "Company") is pleased to announce the closing of the repurchase of a 1% net smelter return (“NSR”) royalty from Sandstorm Gold Ltd. (“Sandstorm”) on its Khundii Gold Project in southwest Mongolia on April 12, 2019 for C$1.2 million.

“Completing this repurchase is accretive for shareholders as the present value of royalty payments implied by the Preliminary Economic Assessment are well in excess of the purchase price,” said Peter Akerley, Erdene’s President and CEO. “With the exploration potential of the Khundii Gold Project license areas, which we are continuing to evaluate as part of our ongoing 2019 exploration program, the benefits of repurchasing could prove even greater.”

As announced on April 21, 2016, Erdene completed a transaction granting Sandstorm a 2% NSR royalty on a select area that included 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 funded this 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 license areas the planned development is considered as a foundation for growth.
