Pershing Gold Reports Upgrade and 34% Increase in Measured and Indicated Resource at Relief Canyon

LAKEWOOD, Colo., July 6, 2015 /PRNewswire/ -- Pershing Gold Corporation (NASDAQ:PGLC) ("Pershing Gold" or the "Company") announces an upgraded NI 43-101 compliant resource estimate (the "resource") for its Relief Canyon Project in Pershing County, Nevada.  The upgraded resource shows a Measured and Indicated Resource of 739,000 ounces of gold and an Inferred Resource of 70,000 ounces of gold (see Table 1). This new resource shows a 34% increase in the Measured and Indicated total compared to the 552,000 ounces of Measured and Indicated Resource in our March 2014 estimate (see Figure 1). 

"This resource update immediately creates additional shareholder value.  The last phase of the 2014 drilling program focused on development drilling to tighten up drill hole spacing in the high-grade zones of the North Target Area," stated Stephen D. Alfers, Pershing Gold President, CEO, and Executive Chairman. "We expect the 34% increase in the measured and indicated resource and the additional ounces identified in the stockpile will expand and upgrade the in-pit resource and correspondingly increase the current net asset value of the project.  For the remainder of 2015, we plan to continue to aggressively drill the deposit to build on the high-grade intercepts encountered earlier this year, and to further add ounces as we move Relief Canyon towards production," Alfers said.  

Pershing Gold has identified an Inferred Resource of 24,000 ounces of gold in an historic stockpile located just southwest of the existing pits.  The gold ounces remaining in the stockpile, which are included in the tabulation of Inferred-Oxide Resource shown in Table 1, are the result of much higher cutoff grades used by past operators. Gold-bearing material from this stockpile is planned to be processed in the first year of production at Relief Canyon. 

The Company is currently in the process of executing its 2015 drilling program, which is planned to include 100 core holes and approximately 75,000 feet (nearly 23,000 meters) of drilling.   Pershing Gold currently has two core rigs drilling on site and expects to add two additional drill rigs later this week.  The third core-drill rig will be operating in the Jasperoid Target Area.  The fourth drill rig will be working on the Buffalo Pediment, an exploration target located approximately one and a half miles north of the existing pits.  The Relief Canyon deposit remains open in all directions. The Company plans to incorporate the results of this aggressive 2015 drilling program into a further updated NI 43-101 resource estimate upon completing of the 2015 program.  

With the completion of the upgraded resource Pershing Gold plans to conduct a thorough economic study on Relief Canyon, including estimates of production rates, cash costs, all-in-sustaining-costs, life-of-mine, net asset value estimates, and other key metrics. The mine plan supporting this study will include all measured and indicated ounces and the inferred ounces in the southwest stockpile.  The Company plans to consider the timing of a start-up decision at Relief Canyon based on this economic study.

The upgraded resource includes the results from the Company's 2014 through January 2015 drilling program, which included 141 core holes and approximately 80,000 feet (24,000 meters) of drilling.  Since initiating its work in the fall of 2011 to expand the Relief Canyon deposit, Pershing Gold has drilled a total of 304 holes and approximately 164,000 feet (50,000 meters).  The updated resource is based on data from these holes plus many of the 588 holes drilled by previous owners of the mine.  

This resource was prepared following the definitions and guidelines adopted by the Canadian Institute of Mining, Metallurgy and Petroleum. These definitions and guidelines satisfy the requirements of Canadian National Instrument 43-101. It was completed by Mine Development Associates of Reno, Nevada, under the direction of Paul Tietz, CPG, and was effective June 26, 2015. Geologic modeling of the deposit was completed in collaboration with Pershing Gold's geologists.  Standard practices were followed including the development of gold domain grade boundaries.  Gold domains represent natural grade populations that occur within a specific geologic setting.  The gold domain boundaries are used to control the estimation of grade thereby reducing the risk of over-estimating the volume (tons) of higher-grade material within the resource model.

Scientific and Technical Data
All scientific and technical information related to drill and surface samples for the Relief Canyon project has been reviewed and approved by Larry L. Hillesland, Certified Professional Geologist #11720, who is a Qualified Person under the definitions established by Canadian National Instrument 43-101. Drill core at Relief Canyon is boxed and sealed at the drill rig and moved to the Relief Canyon logging and sample preparation facilities by trained personnel. The core is logged and split down the center using a typical table-fed circular rock saw. One half of the core is sent for assay to Skyline Assayers & Laboratories of Sparks, Nevada, while the other half is returned to the core box and stored at Relief Canyon in a secure, fenced-off, area. Pershing Gold Corporation quality assurance/quality control (QA/QC) procedures include the regular use of blanks, standards, and duplicate samples.

Cautionary Note to United States Investors Regarding Estimates of  Measured, Indicated, and Inferred Resources
This press release uses the terms "Measured," "Indicated" and "Inferred resources", which are defined in Canadian Institute of Metallurgy guidelines, the guidelines widely followed to comply with Canadian National Instrument 43-101. We advise U.S. investors that these terms are not recognized by the United States Securities and Exchange Commission (the "SEC"). The estimation of measured and indicated resources involves greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. Mineral resources are not mineral reserves, and U.S. investors are cautioned not to assume that measured or indicated mineral resources will be converted into reserves. Inferred mineral resources have a high degree of uncertainty as to their existence, and their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource exists, or is economically or legally viable. US investors are urged to consider closely the disclosure in our Form 10-K and other SEC filings. You can review and obtain copies of these filings from the SEC's website at http://www.sec.gov/edgar.shtml.
