Pershing Gold Concludes 216 Phase 1 Drilling Program and Shifts Focus to Pre-Feasibility Study and Restart of Relief Canyon LAKEWOOD, Colo., Jan 9, 217 (PR NEWSWIRE) Pershing Gold Corporation (NASDAQ:PGLC) (TSX: PGLC) (FWB:7PG1) ("Pershing Gold" or the "Company"), the emerging Nevada gold producer, today provides an update on the progress towards production at its Relief Canyon Mine in Pershing County, Nevada. With the recent volatility in the gold price, the economics for Relief Canyon remain strong as a low cost, low CAPEX project in comparison with our North American peers, stated Stephen D. Alfers, Pershing Gold President, CEO, and Executive Chairman. Early this year the Company plans to publish a third-party Pre-Feasibility Study on Relief Canyon. This study is expected to continue to bolster the confidence in the Relief Canyon project, Alfers explained. Additionally, we have completed the 216 Phase 1 Drilling Program at Relief Canyon, which successfully extended high-grade mineralization with step-out drilling to the west. We also report promising results with our Phase 2 drilling, south of Relief Canyon. We are currently evaluating the results of this drilling in consideration of follow up drilling programs. That said, our main focus will be re-starting the Relief Canyon mine, said Alfers. Pre-Feasibility Study and Progress Towards Production Pershing Gold is nearing the completion of the third-party Pre-Feasibility Study ( PFS ) on the Relief Canyon mine that it initiated earlier this year. The PFS will refine the underlying assumptions used in the 216 Preliminary Economic Assessment ( PEA ) on Relief Canyon, which is available on the Company s website at www.pershinggold.com. Mine Development Associates, McLelland Laboratories, Inc. and Kappes, Cassiday and Associates, all of Reno, NV, have been commissioned to complete the PFS. Pershing Gold expects the PFS to be published in early 217. The PFS is a key step to allow the Company to define reserves at Relief Canyon under Canadian National Instrument 43-11 and is expected to provide a higher degree of confidence in the Relief Canyon project. Key components of the PFS include the following: Incorporation of a geotechnical pit slope evaluation completed by Golder Associates of Reno, NV. Evaluation of an updated resource model incorporating new exploration drilling. Detailed capital and operating cost comparison of contract versus self-mining. Detailed capital and operating cost comparison of truck stacking versus conveyor stacking of crushed and agglomerated ore on the leach pad. Incorporation of additional metallurgical testing to establish ore agglomeration parameters. Trade-off study of line versus generated electrical power. Additionally, the PFS will provide refined costs for all capital and operating expenses for the 1
restart of Relief Canyon. Permitting On December 22, 216, the Nevada Division of Environmental Protection ( NDEP )/Bureau of Mining Regulation and Reclamation Phase issued the Reclamation Permit for Phase I expansion of the Relief Canyon Mine. With the receipt of this permit, along with the Bureau of Land Management ( BLM ) approval of the Relief Canyon Mine Expansion announced in August of 216, Pershing Gold has received the principal permits to initiate the restart and expansion of the Relief Canyon Mine. Similar to the previously approved BLM Plan of Operation, the NDEP Reclamation Permit authorizes Pershing Gold to create 68.7 acres of surface disturbance on public and private land, expand and deepen the open-pit mine, construct a new waste rock storage area, and significantly increase the exploration drilling area to allow testing of high-priority targets around the existing pit. Other key items in the ongoing process of permitting the Relief Canyon Mine include water pollution control and air quality permits. On December 21, 216, NDEP issued a public notice stating that they had made the tentative decision to approve Pershing Gold s application to modify and renew the current Water Pollution Control Permit. With this announcement, NDEP started the 3-day public comment period for this permit. The comment period will end on January 2, 217. Pershing Gold anticipates that the NDEP will issue the Water Pollution Control Permit modification and renewal shortly thereafter. Pershing Gold is working closely with NDEP s Bureau of Air Pollution Control to finalize the air quality permitting process. The Company expects that NDEP will issue the air quality permits in the first quarter of 217. 216 Drilling Program Phase 1 Final Results Pershing Gold has received the final results from Phase 1 of its 216 Drilling Program (the Program ), listed in Table 1 below. A complete list of results received to date is available on our website at www.pershinggold.com. Results are reported in feet ( ft ) and meters ( m ), and in grams per tonne ( gpt ) and ounces per ton ( oz/ton ) of gold ( Au ) or silver ( Ag ). Notable intercepts from RC16-49 include: o RC16-49 including: 24.1 ft (7.3 m), 1.83 gpt,.53 oz/ton Au including: 5. ft (1.5 m), 13.933 gpt,.47 oz/ton Au The Phase 1 Drilling Program was designed to extend the western boundary of economic mineralization at Relief Canyon. RC16-49 continues to confirm that significant portions of the western margin of the mineral zones remain open to the west. RC16-49 is a 55 ft (167.6 m) offset to RC16-462 and a 29 ft (88.4 m) offset to RC16-475. The intercept in RC16-462 includes eight zones totaling 166.3 ft (5.7 m) with an average grade of 1.597 gpt,.46 oz/ton Au, and 23.5 gpt,.7 oz/ton Ag that the Company reported on September 9, 216. A plan view including these drill holes is shown below in Figure 1. 2
The Phase 1 drilling successfully expanded the North target area resource to the west and southwest where it remains open. This drilling continued to support the dominance of relatively low angle structural controls and continuity of mineralization and grade down dip. The Lower and Jasperoid Zones continue to produce high grades of gold with very good cyanide soluble results at depths to >9 ft (274 m).

This Phase 1a Program and other follow up programs could include step-out drilling to continue following the mineralization from Relief Canyon down dip to the west and southwest as well as infill drilling to expand the current economic pit limit at Relief Canyon. Geologic modeling of the higher grades encountered in the area of RC16-462 is currently in progress with additional drilling under consideration for 217. Phase 2 Drilling Program Pershing Gold has initiated Phase 2 of its 216 Drilling Program. Phase 2 is focused on extending mineralization south of the South Pit and the Lightbulb Pit, as well as on discovering satellite deposits that could be processed at the existing heap leach and ADR facilities at Relief Canyon.

The Company is encouraged by the two intervals in hole RC16-498 because they occur along the 3
contact of the South Humboldt Thrust where deformed siliciclastics of the Grass Valley Formation are in thrust contact with the underlying carbonates of the Cane Springs Formation. Both of these intervals are found along altered gabbro contacts, which are illustrated in Figure 2 below. Figure 1 These structural contacts are key elements controlling the distribution of gold in the resource at Relief Canyon. Surface geological mapping and resistivity psuedosections indicate the intercepts in drill hole RC16-498 are located along a steepened thrust ramp. The depth to the South Humboldt Thrust shallows and flattens to the northeast as noted in Section 17-1 in Figure 2 below. Another key element to potential for resource growth at Relief Canyon is the 4
presence of a strong N4W structural corridor that cuts through the southeast extension target area. This N4W structural corridor is a significant structural control on gold at the Relief Canyon project. The Phase 2 drilling program is wide spaced, with the drill hole spacing averaging from 5 to 1,2 ft (152 to 366 m). This drilling is testing coincident geological, geochemical, and geophysical targets south and southeast of the old Relief Canyon Mine pits. The great majority of this highly prospective area has not previously been drilled. Phase 2 drilling completed to date has vectored toward the Southeast Extension target area (Figure 1).
