Prophecy Development Corp. Prepares to Drill

Gibellini Vanadium Project

Vancouver, British Columbia, April 30, 2018 – Prophecy Development Corp. (“Prophecy” or

the “Company”) (TSX:PCY, OTCQX:PRPCF, Frankfurt:1P2N) is initiating preparations for its

exploration and verification drilling program on the Gibellini vanadium project in Q2 2018. A total

of 4,880m of reverse circulation drilling in 64 holes are planned in the following target areas:

Gibellini: 33 holes total 2,740 meters

The report ( the “Technical Report ”) prepared by Amec Foster Wheeler E&C Services Inc .

(“AMEC”) according to National Instrument 43-101, Standards of Disclosure for Mineral Projects

(“NI 43-101”) with an effective date of November 10, 2017 , estimated combined Measured and

Indicated Mineral Resource of 22.01 million tons at a weighted average grade of 0.294% V 2O5,

containing 129.28 million pounds V 2O5. The Inferred Mineral Resource estimate is 9.8 2 million

tons at a weighted average grade of 0.19% V2O5 containing 37.27 million pounds V2O5.

1) The Qualified Person for the estimate is Mr. E.J.C. Orbock III, RM SME, an AMEC employee.

The Mineral Resource estimate has an effective date of 10 November 2017.

(2) Mineral Resources are reported at various cut -off grades for oxide, transition, and reduced

material.

(3) Mineral Resources are reported within a conceptual pit shell that uses the following

assumptions: mineral resource V2O5 price: $10.81/lb; mining cost: $2.21/ton mined; process cost:

$13.14/ton processed; general and administrative (G&A) cost: $0.99/ton processed; metallurgical

recovery assumptions of 60% for oxide material, 70% for transition material and 52% for reduced

material; tonnage factors of 16.86 ft3/ton for oxide material, 16.35 ft3/ton for transition material

and 14.18 ft3/ton for reduced material; royalty: 2.5% net smelter return (NSR); shipping and

conversion costs: $0.37/lb. An overall 40º pit slope angle assumption was used.

(4) Rounding as required by reporting guidelines may result in apparent summation differences

between tons, grade and contained metal content. Tonnage and grade measurements are in US

units. Grades are reported in percentages.

Thirty-three (33) infill drill holes have been planned to increase the confidence level of a potential

near-surface higher-grade starter pit (“HSP”) with the following historic drilling highlights:

A successfully delineated HSP could be incorporated in the early mining sequence that can

potentially boost metal recoveries, increase production throughput, and lead to faster investment

payback.

Louie Hill: 28 holes total 1,765 meters

Also disclosed in the Technical Report is an inferred NI 43-101 compliant resource for the Louie

Hill deposit of 7.06 million tons at a grade of 0.284% V 2O5, or 40.2 million pounds of contained

V2O5 metal with 1,765 meters of drilling. A total of 28 holes are planned for i nfill and expansion

which are aimed to increase total resource tonnage, upgrade resource confidence level, and to

delineate whether higher grade mineralized intercepts comprise continuous zones, based on the

following past drill highlights:

Middle Earth, Big Sky and Northeast Regional Prospects: 3 holes total 375 meters

Regional prospects are all within a three-kilometer trend of Prophecy’s controlled claims.

Combined, the three prospects covers 2.5 squared kilometers which is over twice the size of

Gibellini’s foot print (refer to plan map).

These prospects contain exposures of the same host rocks found at Gi bellini and Louie Hill,

known as the Woodruff Formation, which is comprised predominantly of various mudstones and

lesser chert.

Over 390 trench results from Big Sky and Northeast targets and core samples from the historic

drilling at Middle Earth target all demonstrated appreciable vanadium grades. Below are

highlights from past trench and drilling:

Northeast TRENCH Nt3 3.0 60.0 57.0 0.270

A total of three holes total 375 meters are designed to drill test the three regional prospects. A

discovery from those prospects could turn the area into a vanadium district play with already

established vanadium resources at Gibellini and Louie Hill.

Concluding Comments

Danniel Oosterman, VP, Exploration states: “This carefully planned drill program could:

1. Establish a higher-grade starter pit that accelerates future project payback;

2. Increase resource tonnage and upgrade confidence level of Gibellini and Louie Hill

resources; and

3. Expand the project into a vanadium district play with multiple discoveries.

Gibellini is the only black shale project in the world we are aware of, that can achieve up to 70%

high metallurgical recoveries, as referenced in the November 2017 Technical Report, through

heap leach without a costly, energy -intensive, high temperature pre -roasting step. With

permitting, EPCM (engineering , procurement and construction management), and vanadium

product off-take sales initiatives already underway, Prophecy’s Gibellini project offers the fastest

pace, best leverage and a direct play in vanadium that reflects increased vanadium prices in a

politically-safe, mining-friendly jurisdiction of Nevada, USA.“

Prophecy expects to report findings from an in dependent preliminary economic assessment of

the Gibellini vanadium project in May 2018. Also in May, Prophecy expects to submit updated

base line studies and an updated Plan of Operations for the Gibellini vanadium project to the

Bureau of Land Management.
