VANCOUVER, BRITISH COLUMBIA--(Marketwired - June 18, 2015) - Prophecy Development Corp. ("Prophecy" or the "Company") (TSX:PCY)(OTCQX:PRPCF)(FRANKFURT:1P2) is pleased to announce receipt of an independent mineral resource estimate for the Company's Pulacayo silver-zinc-lead project, prepared in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves referenced in National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"). The effective date of the estimate is June 16, 2015. The Pulacayo deposit is located in Bolivia, 107km northeast of Sumitomo Corporation's San Cristobal silver mine, 185km southwest of Coeur Mining, Inc.'s San Bartolome silver mine, and 139km north of Pan American Silver Corp.'s San Vicente silver mine. The mineral resource estimate was prepared by Mercator Geological Services Limited ("Mercator") under supervision of Michael Cullen, P.Geo., who is an independent Qualified Person under NI 43-101. Results of the mineral resource estimate prepared by Mercator for the Pulacayo project are presented below in Table 1. A technical report documenting the resource estimate and prepared in accordance with NI 43-101 will be filed by the Company on the System for Electronic Document Analysis and Retrieval (SEDAR) within 45 days of this press release.

Table 1: Pulacayo Indicated and Inferred Mineral Resource Statement Details

Notes:

1. Mineral resources are estimated in conformance the CIM Standards referenced in NI 43-101.
2. Raw silver assays were capped at 1,700 g/t, raw lead assays were capped at 15% and raw zinc assays were capped at 15%.
3. Silver equivalent Ag Eg. (g/t) = Ag (g/t)*89.2% + (Pb% *(US$0.94/ lb. Pb /14.583 Troy oz./lb./US$16.50 per Troy oz. Ag)*10,000*91.9%) + (Zn% *(US$1.00/lb. Zn/14.583 Troy oz./lb./US$16.50 per Troy oz. Ag)*10,000*82.9%).
   Metal prices used in the silver equivalent calculation are US$16.50/Troy oz. Ag, US$0.94/lb Pb and US$1.00/lb Zn. Metal recoveries 89.2% Ag. 91.9% Pb. 82.9% Zn. used in the silver equivalent equation reflect historic metallurgical results disclosed previously by Apogee Silver Ltd.
4. Metal grades were interpolated within wireframed, three dimensional silver domain solids using Geovia-Surpac Ver. 6.6.1 software and inverse distance squared interpolation methods. Block size is 10m(X) by 10m(Z) by 2m(Y). Historic mine void space was removed from the model prior to reporting of resources.
5. Block density factors reflect three dimensional modeling of drill core density determinations.
6. Mineral resources are considered to have reasonable expectation for economic development using underground mining methods based on the deposit history, resource amount and metal grades, current metal pricing and comparison to broadly comparable deposits elsewhere.
7. Rounding of figures may result in apparent differences between tonnes, grade and contained ounces.
8. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
9. *Mineral resource statement cut-off value; resource statement values are presented in bolded form.
10. **Tonnes are rounded to nearest 10,000.

Between 2006 and 2012, a total of 69,739 metres of diamond drilling (226 surface and 42 underground drill holes) was conducted at Pulacayo, results of which support the mineral resource estimate reported in this news release. Verification and validation checks on the sampling method, sample shipment documentation and analytical data were carried out by Mercator in support of the current resource estimate and Prophecy independently carried out additional database checks with satisfactory results. Review of Quality Control and Quality Assurance program results that include analyses for duplicate, blank, certified reference material and third party check sample materials was also performed by Mercator with acceptable results. The methods and assumptions used to interpolate metal grade including variography, search ellipse orientation and dimensions, drill hole density, and geological interpretation are considered reasonable for this type of epithermal mineral deposit. Block model results were compared to assay composites and ordinary kriging results and all show acceptable correlation to underlying data. The Pulacayo site is currently permitted for production at a milling rate of 560 tonnes per day and no known legal, political, environmental, or other risks that would materially affect potential future development have been identified by Prophecy at the effective date of the current (June 16th, 2015) mineral resource estimate.

The contained metals within the June 16, 2015 resource estimate by Mercator are presented in Table 2.

Management Comment on Future Mine Planning and Mill Purchase

Approximately 85% of the resource tonnage identified at the 500 g/t Ag Eq. cut-off value occurs within 150 meters vertical distance from the main San Leon tunnel, which may facilitate future mineral extraction. Drilling intercept density decreases with depth and ultimately limits the vertical extent of resource definition. New drilling in deposit strike and dip extension areas has potential to discover additional resources.

The Company's research has shown that relatively few silver deposits have been defined at resource cut-off values of 500 g/t Ag Eq. or more. The shallow-depth of the high grade Pulacayo resource model is a positive factor contributing to internal mine planning and assessment programs scheduled to be completed during July of 2015.

Since acquiring the Pulacayo project from Apogee Silver Ltd. ("Apogee") in January 2015, Prophecy has been in general discussions with several local vendors with respect to purchasing a 500 tonne per day mineral processing (grinding and flotation) plant. This planned throughput level is half of that previously planned by Apogee, and complies with the approved Environmental Impact Assessment currently in place for the Pulacayo site. If implemented, this smaller operational footprint is expected to result in reduced capital expenditures.

The final plant design will be determined after more comprehensive review of the resource block model and mine planning assessments, plus consideration of results of both historic toll-milling programs and on-going bench-scale metallurgical testing programs that are focused on high grade material.

Pulacayo Concentrate Offtake and Project Construction:

The Pulacayo deposit is situated in a prolific silver mining region that supports a number of active silver mines within a radius of 200km of the site. These include the San Cristobal, San Bartolome (Cerro Rico) and San Vicente Mining operations that, according to public records, produced over 30 million combined ounces of silver in 2014. The Pulacayo site is 20km by paved road to rail services at Uyuni, connecting to the port of Antofagasta, Chile.

During over 18 months (2012 to 2013) of trial mining and toll-milling by Apogee, Pulacayo produced high grade silver-lead (6,000 g/t Ag) and silver-zinc flotation concentrates that were sold to Trafigura Beheer BV (see Apogee press release dated January 15, 2013). The Company is currently working towards securing concentrate offtake agreements at commercially competitive terms. The potential for future project financing from this business sector is also being investigated. As noted earlier, the Pulacayo site is fully permitted for production and a decision regarding commencement of concentrator construction and related infrastructure improvements is scheduled for July 2015.

Pulacayo Background and District Potential:

Historic Pulacayo production was predominantly from the Tajo vein system which extends over a strike length of more than 2.5km and to a depth of at least 1,000 meters. Total production from the Pulacayo mine during the period 1857 to 1959 is estimated by the National Geological and Mineral Service of Bolivia (SERGEOTECMIN) to be 678 million ounces of silver, 200,000 tons (181,400 tonnes) of zinc and 200,000 tons (181,400 tonnes) of lead (SERGEOTECMIN Bulletin No. 30, 2002). Prior resource drilling only covered approximately 20% of the Tajo vein system strike length. With new drilling, Prophecy feels that there is potential to discover additional high grade resources along the Tajo structure. The Company is examining Pulacayo as a large-scale district silver project that includes a number of other well-known silver occurrences and anomalies additional to the Tajo system. These include the Paca, Pacamayo, El Abra, and Pero prospects that all occur within 10km of the Pulacayo site. The Company classifies these as having excellent potential for discovery of future mineral resources through application of modern exploration techniques. The reader is directed to the Company's press release dated April 2, 2015 and its website for further project information.
