Prophecy Files Preliminary Economic Assessment

for Gibellini Vanadium Project

Vancouver, British Columbia, June 25, 2018 – Prophecy Development Corp. (“Prophecy”

or the “Company”) (TSX:PCY, OTCQX:PRPCF, Frankfurt:1P2N) is pleased to announce the

filing of a technical report prepared in accordance with National Instrument 43-101, Standards of

Disclosure for Mineral Projects (“NI 43-101”) regarding a preliminary economic assessment (the

“PEA”) for its Gibellini vanadium project in Eureka, Nevada.

The PEA is available under the Company’s profile on SEDAR at www.sedar.com.

Prophecy’s news release dated May 29, 2018, summarizes the assumptions and key results

contained in the PEA.

The 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 PEA will

be realized. Mineral resources are not mineral reserves and do not have demonstrated

economic viability.

Qualified Persons

The PEA was prepared by staff of Amec Foster Wheeler E&C Services Inc. (" AMEC"), under

the direction of Kirk Hanson, who is independent of Prophecy. The following AMEC staff served

as Qualified Persons (QPs) as defined in NI 43-101:

Mr. Kirk Hanson, P.E., Technical Director, Open Pit Mining;

Mr. Edward J.C. Orbock III, RM SME, Principal Geologist and US Manager, Consulting;

Mr. Edwin Peralta, P.E., Senior Mining Engineer; and

Dr. Lynton Gormely, P.Eng., Consultant Metallurgist.
