Pershing Gold Files Plan of Operations for Future Expansion of Relief Canyon Mine

LAKEWOOD, Colo., June 20, 2018 /PRNewswire/ -- Pershing Gold Corporation (NASDAQ:PGLC) (TSX: PGLC) (FWB:7PG1) ("Pershing Gold" or the "Company"), an emerging Nevada gold producer advancing the Relief Canyon Mine, is pleased to announce that it submitted the 2018 Plan of Operations ("2018 Plan") Modification for the Phase II expansion of the mining and heap leach facilities to the Bureau of Land Management ("BLM") on June 15, 2018. Pershing Gold submitted this permit application to the Nevada Department of Environmental Protection ("NDEP") on June 18, 2018.

"We are now permitted to start construction and mining for Phase I mining at Relief Canyon and we expect to start construction upon finalization of financing," stated Stephen Alfers, Chairman, CEO and President of the Company. "The submission of this 2018 Plan starts the federal and state permitting processes for the Phase II expansion paving the way for a seamless transition from Phase I to Phase II," stated Alfers. "The extensive environmental baseline studies we commissioned to support the 2018 Plan demonstrate there are no significant environmental issues associated with Phase II, which should facilitate timely permit acquisition. This process will allow us to move smoothly from Phase I into Phase II in the future."

The Company currently has all of the necessary permits for its Phase I mining and heap leaching operation. The approved Phase I project authorizes mining the Phase I pit, the full build-out of the heap leach pad to accommodate leaching of the Phase I ore, and construction of a new waste rock storage facility. The anticipated mine life for Phase I is roughly two years following approximately six to eight months of project construction.

The proposed expansion described in the 2018 Plan includes enlarging and deepening the open-pit mine; building 106 acres of new heap leach pad space adjacent to the previously approved pads to hold the Phase II ore and constructing a new process pond; expanding the authorized waste rock storage facilities for the waste rocks to be mined from the Phase II pit; and constructing ancillary facilities to support the Phase II operation.

Pershing Gold retained expert third-party consultants to augment the environmental baseline studies and impact analyses that were done for the Phase I operation. Examples of the Phase II studies include:

• Detailed waste characterization studies consisting of both static and kinetic tests (e.g., humidity cell tests) that evaluate the geochemical behavior of the Phase II waste rocks and the rocks that will be exposed in the Phase II pit wall. McGinley & Associates ("McGinley") of Reno, NV prepared these studies which show the Phase II rocks are not acid generating and do not leach significant metals;
• Additional groundwater baseline studies and conceptual and numerical groundwater models for the Phase II pit. WSP USA of Reno, NV and Golder Associates of Redmond, WA prepared these studies which show that mining the Phase II pit will require very modest dewatering (a maximum of roughly 900 gallons per minute during the last three months of mining), dewatering will not impact springs or third-party water rights, and there will be a post-mining pit lake that will be a groundwater sink;
• A predictive pit lake water quality study prepared by McGinley that shows the pit lake will meet all NDEP water quality standards and will be safe for wildlife; and
• A Rapid Infiltration Basins ("RIBs") technical investigation by McGinley demonstrating that there will be insignificant groundwater mounding and no water quality impacts associated with operation of the RIBs to manage the dewatering water.
