Vancouver, British Columbia, November 20, 2017 – Prophecy Development Corp. (“Prophecy” or the “Company”) (TSX:PCY, OTCPK:PRPCF, Frankfurt:1P2N) has received an independent technical report titled “Gibellini Vanadium Project Nevada, USA NI 43-101 Technical Report” with an effective date of November 10, 2017 (the “Report”) prepared by Amec Foster Wheeler E&C Services Inc. on the Gibellini vanadium project (the “Project”) which has been filed under the Company’s profile on the System for Electronic Document Analysis and Retrieval (SEDAR) at www.sedar.com.

The Project is located in Eureka County, Nevada, about 25 miles south of the town of Eureka, and is easily accessed by a graded gravel road extending south from US Highway 50. Nevada is featured in the 2016 Fraser Institute survey of mining companies as the fourth most attractive jurisdiction for mining investment globally.

The Report describes resources according to category following the guidelines of the CIM Definition Standards for Mineral Resources and Mineral Reserves.

Two mineral resource estimates were prepared, one for the Gibellini deposit and the second for the Louie Hill deposit.

Gibellini Deposit

The Report has estimated 7.85 million tons at a weighted average grade of 0.316% vanadium pentoxide (V₂O₅) in the Measured category and 14.16 million tons at a weighted average grade of 0.281% V₂O₅ in the Indicated category leading to a total combined Measured and Indicated Mineral Resource of 22.01 million tons at a weighted average grade of 0.294% V₂O₅. Total contained metal content of the Measured and Indicated Mineral Resources is 129.28 million pounds V₂O₅. The Inferred Mineral Resource estimate is 9.82 million tons at a weighted average grade of 0.19% V₂O₅. The total contained metal content of the Inferred Mineral Resource estimate is 37.27 million pounds V₂O₅. The table below summarizes the Gibellini deposit estimate.

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

Louie Hill Deposit

The Louie Hill deposit lies approximately 1,600 ft south of the Gibellini deposit.

The Report estimated an Inferred Mineral Resource of 7.06 million tons at a weighted average grade of 0.284% vanadium pentoxide (V₂O₅). The oxidation domains were not modeled. The total contained metal content of the estimate is 40.16 million pounds V₂O₅. The table below summarizes the Louie Hill deposit estimate.

Louie Hill Deposit Mineral Resource Statement
Resource Category	Domain	Cut-off V2O5 (%)	Tons (M)	Grade (%V2O5)	Metal Content (M lbs V2O5)
Inferred	Not modeled	0.116	7.06	0.284	40.16

Notes to accompany mineral resource table for Louie Hill:
(1) The Qualified Person for the estimate is Mr. E.J.C. Orbock III, RM SME, an Amec Foster Wheeler employee. The Mineral Resources have an effective date of 10 November, 2017. The resource model was prepared by Mr. Mark Hertel, RM SME.
(2) Oxidation state was not modeled.
(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 mineralized material; tonnage factors of 16.86 ft3 /ton for mineralized material, royalty: 2.5% net smelter return (NSR); shipping and conversion costs: $0.37/lb. For the purposes of the resource estimate, an overall 40º 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.

A total of 280 drill holes (about 51,265 ft) have been completed on the Project since 1946, comprising 16 core holes (4,046 ft), 169 rotary drill holes (25,077 ft; note not all drill holes have footages recorded) and 95 RC holes (22,142 ft).

The vanadium-host black shale unit ranges from 175 to over 300 ft thick and overlies gray mudstone. The shale has been oxidized to various hues of yellow and orange to a depth of 100 ft. Alteration (oxidation) of the rocks is classified as one of three oxide codes: oxidized, transitional, and reduced.

A feasibility study was commissioned in late 2010 by the previous operator, American Vanadium Corp., and was completed in 2011 (the “2011 Feasibility Study”). The 2011 Feasibility Study assumed a conventional open pit mine using a truck and shovel fleet for mining and a heap leach to produce V2O5 as a bagged product. Prophecy is not treating either the Mineral Reserves resulting from the 2011 Feasibility Study or the economic results of that study as current. No work has been conducted on the Project since 2011. Prophecy has completed no exploration or drilling activities since Project acquisition.

Metallurgy

A heap leach operation without initial roasting step was modeled and designed to produce V2O5 as a bagged product.

Metallurgical test work and associated analytical procedures were performed by recognized testing facilities during the period 1975 to 2011, and the tests performed were appropriate to the mineralization type. Samples selected for testing were representative of the various types and styles of mineralization. Samples were selected from a range of depths within the deposit. Sufficient samples were obtained to ensure that tests were performed on sufficient sample mass. For the purposes of the Mineral Resource estimate, recoveries of 60% for oxide material and 70% for transitional material were considered appropriate. No processing factors were identified from the completed metallurgical test work that would have a significant effect on extraction. The table below summarizes the projected metallurgical recoveries for the three defined oxidation-type domains.

Mill Feed Material Type	Percent Recovery
Oxide	60%
Transition	70%
Reduced	52%

Environmental and Permitting Considerations

Baseline studies conducted in 2010–2011 included studies to document the existing conditions of biological resources, cultural resources, surface water resources, ground water resources, and waste rock geochemical characterization. The baseline data collected would be subject to review and approval by the Bureau of Land Management (the “BLM”) and the Nevada Department of Environmental Protection and other regulatory agencies.

Prior to commencing any mining operations on public lands administered by the BLM, a Plan of Operations describing how a proponent will prevent unnecessary and undue land degradation and reclaim the disturbed areas must be submitted to the BLM.

Both the baseline studies and the Plan of Operations were prepared and submitted by the Project’s previous operator and deemed complete by the BLM in order to start the National Environmental Policy Act process.

John Lee, Chairman of Prophecy, states:

“Gibellini is an exceptionally rare open pit, heap leach vanadium project in Nevada, with low deleterious (less than 1% Fe, Ti, and MgO) elements. In 2018, Prophecy intends to update and accelerate prior feasibility and permitting work. We believe vanadium batteries have a bright future in the United States with strong renewable energy mandates in Texas, Arizona, California, Nevada and many other windy/sunshine states. Our goal is to make Gibellini the first primary vanadium operating mine in North America.”
