Pershing Gold Corporation Reports Fall 2012 Drilling Program Expands
Mineralized Zone 500 Feet Beyond Current Pit Boundaries at the Relief Canyon
Mine
LAKEWOOD, Colo., Dec. 4, 2012 (GLOBE NEWSWIRE) -- Pershing Gold Corporation
(OTCBB:PGLC) is pleased to announce the results of its Fall 2012 drilling
program at the Relief Canyon Mine in Pershing County, Nevada. The results of
this program are expected to contribute new ounces to the Relief Canyon
resource estimate that Roscoe Postle Associates, LTD, USA is currently
preparing and is expected to complete in December 2012.
The drilling program was comprised of 83 holes (27,300 feet) and designed to
accomplish three objectives: (1) to expand the resource in the Main Breccia
Zone south of the existing South and Light Bulb Pits, the southernmost pits at
Relief Canyon; (2) to evaluate the gold mineralization potential in a
1980's-vintage waste rock dump; and (3) to drill a series of piezometer holes
(well holes in which groundwater level may be determined) to define the depth
to the water table in the vicinity of the pits. National Drilling completed
the drilling program using standard reverse circulation procedures.
In commenting on this drilling program, Stephen Alfers, Pershing Gold
Executive Chairman, CEO, and President remarked, "We are very excited about
this round of drilling which expands the area of mineralization in the Main
Breccia Zone up to 500 feet to the south of the southern boundaries of the
South and Light Bulb Pits. It also shows that there is mineralization exposed
at the surface in all three pits and in the waste rock dump southwest of the
pits."
Drill Results
Table 1 (included below) presents the highlights of the drilling results; the
drill hole locations are shown in Figure 1. Significant mineralized intercepts
include RC12-040R with 55 feet of 0.046 ounces per ton ("opt") gold ("Au")
(1.575 grams per ton ("gpt") Au) from 105 to 160 feet and RC12-082R with 100
feet of 0.024 opt Au (0.822 gpt Au). Also notable are the number of holes
shown with mineralization at and near the surface. The mineralization occurs
on unpatented mining claims owned by Pershing Gold's subsidiary, Gold
Acquisition Corp., and on private lands that Pershing Gold sub-leases from
Newmont USA Limited, doing business in Nevada as Newmont Mining Corporation
("Newmont") (NYSE:NEM). Pershing Gold acquired these lands in April 2012 when
it purchased Victoria Resources (US)'s/Victoria Gold Corp.'s (TSX-V:VIT)
interests in Victoria's 2006 mineral lease and sublease with Newmont. The
leased lands are subject to an Area of Interest ("AOI") with Newmont.
Figure 2 shows the expanded area of mineralization in the Main Breccia Zone
target type south of the South and Light Bulb Pits. This mineralized zone
remains open to the south and west. As discussed in our press release dated
July 12, 2012, this mineralized zone is also open to the west. The thickness
of the Main Breccia Zone varies from 10 feet to more than 100 feet. The
Company's drill results indicate that this zone is typically mineralized and
altered wherever it is encountered, with gold grades of 0.005 opt to more than
0.05 opt Au. Please refer to our press release dated July 12, 2012.

The Main Breccia Zone is developed at a fault contact between the Grass Valley
and Cane Springs Formations. As shown in Figure 2, previous mining activities
at Relief Canyon exploited – but did not exhaust – this mineralized zone. As
described in our press release dated September 17, 2012, two other gold
bearing zones are also present at Relief Canyon: the Lower Zone, which is
approximately 200 feet below and sub-parallel to the Main Breccia Zone; and
the Feeder Zones. Please refer to our press release dated September 17,
2012. [http://ir.stockpr.com/pershinggold/company-news/detail/353/pershing-gold-reports-results-and-progress-toward-reopening-the-relief-canyon-mine.]
Waste Rock Dump Drilling Program
The second element of the Fall 2012 drilling program was to determine whether
the waste rock dump located in Section 20 southwest of the South Pit contains
gold. Based on the results obtained from the 16 shallow holes drilled in this
waste rock dump, Pershing Gold is encouraged that these previously mined rocks
may become a future resource.
The waste rock dump contains over 1 million tons of rock that was considered
too low-grade to be placed on the heaps and leached when it was mined in the
late 1980s, when gold prices varied from about $360 to $500 per ounce. At
today's gold prices, economic cut-off grades are significantly lower;
consequently, this historic waste rock dump may have potentially mineable gold
values. Significant intercepts in the waste rock dump include RC12-103R from 0
to 80 feet with 0.010 opt Au (0.342 gpt Au), RC12-104R from 0 to 70 feet with
0.009 opt Au (0.308 gpt Au), and RC12-106R from 35 to 65 feet with 0.10 opt Au
(0.342 gpt Au).
Depth to Groundwater Study
The third component of the Fall 2012 drilling program was to drill nine holes
that were completed as piezometers specifically designed to measure the depth
to groundwater in the vicinity of the pits. Figure 1 shows the piezometer
locations. Schlumberger Water Services of Reno, NV helped design and implement
this hydrogeological investigation.
In addition to providing data on the elevation of the water table directly
below and near the three pits, several of the piezometers intercepted gold
mineralization such as RC12-033R (located in the Light Bulb Pit) with from 0
to 125 feet with 0.012 opt Au (0.041 gpt Au), and RC12-094R (located in the
North Pit) from 0-20 feet with 0.036 opt Au (1.23 gpt Au). The two
southernmost piezometers (RC12-087R and RC12-088R), which are located well
south of the South and Light Bulb Pits, also contain mineralized intercepts as
shown in Table 1.
Plans for the Remainder of 2012
All drill results from the 127 drill holes (61,000 feet) that have been
completed since late 2011 will be incorporated into a new resource estimate
that is being prepared by Roscoe Postle Associates, LTD, USA. The new resource
estimate is anticipated to be completed in December of 2012.
The Company has initiated a detailed mapping exercise in the pits and adjacent
areas to collect structural data that will help refine our understanding of
the complex geology at Relief Canyon. Additionally, this work will identify
new drill targets that we plan to test during the first half of 2013.
Detailed geologic mapping and rock sampling of Pershing Gold's extensive land
position in the Pershing Pass area at the south end of the Humboldt Range is
currently in progress. This work is expected to generate several drilling
targets that will be tested in 2013.
Plans for Early 2013
The Company plans to continue its efforts to expand the gold resource at
Relief Canyon in early 2013 with a diamond drilling program designed to extend
gold mineralization in the Main Breccia Zone further to the south in Sections
20 and 21. This program will include some infill drilling along the margins of
the North and South Pits.
The Company plans also to continue the ongoing effort to refine its
understanding of the Relief Canyon geologic system and the controls on
mineralization. So far, this work has developed two new target concepts that
are expected to be tested as part of the 2013 drilling program: (1) the
potential for north-trending, steeply-dipping feeder zones north of the North
Pit; and (2) whether thrust faults are one of the primary controls on
mineralization and have potentially created stacked mineralized zones, (e.g.;
the Main Breccia Zone mineralization on top of the Lower Zone
mineralization). The Company plans to test this concept in 2013 with deep core
holes south of the currently defined Lower Zone.
"Since acquiring Relief Canyon in August 2011, Pershing Gold has significantly
advanced this asset through a program of intensive and strategic exploration
drilling and ongoing work focused on reopening the mine and heap leach
processing facilities," commented Stephen Alfers. "We are especially
enthusiastic about the Fall drilling campaign which, along with Pershing
Gold's previous drilling, has shown that gold mineralization in the Main
Breccia Zone is open to both the south and the west. The presence of gold in
the historic waste rock dump, in the Feeder Zone and the Lower Zone presents
the possibility that this material could add ounces to the resource. These
three opportunities are among the low-hanging fruit that we intend to evaluate
further with future drilling, sampling, and metallurgical testing."
