Quotes from the Company:

“Erdene continues to make solid progress developing the high-grade, open-pit Khundii Gold Project,” said Peter Akerley, Erdene’s President and CEO. “During the first quarter we awarded the Khundii Gold Project Pre-Feasibility Study (“PFS”) contract to Tetra Tech, Inc. and engaged Sustainability East Asia LLC to lead the Environmental and Social Impact Assessment. Mining license applications are well underway, and we recently received government approval of registration of the Bayan Khundii deposit, the major milestone in the license application process.”

“In April, the Company launched an 1,800 metre drilling program focused on increasing confidence in the Khundii Gold Project resource, confirming ultra-high gold grades and expanding the Bayan Khundii deposit to support the PFS,” continued Mr. Akerley. “Drill samples have been sent to the laboratory for analysis and we expect to share results by mid-May.”

Q1-2019 Highlights and Subsequent Events:

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.

Erdene initiated a NI 43-101 Pre-Feasibility Study (“PFS”) for the Khundii Gold Project in March 2019. Led by Tetra-Tech, Inc., with support from Sustainability East Asia LLC for Environmental and Social Impact studies, and Blue Coast Laboratories, for Metallurgical analysis, the PFS is scheduled to be announced in Q3-2019.
