Seabridge Gold Plans $15M Drill Campaign Targeting High-Grade

Seabridge Gold Plans $15M Drill Campaign Targeting High-Grade at KSM 
Program to Focus on Resource Estimate at Deep Kerr Core Zone
Three More Prospective High-Grade Core Zones Also Targeted in Next
Year's Program 
TORONTO, CANADA -- (Marketwire) -- 12/12/12 -- Seabridge Gold
(TSX:SEA)(NYSE:SA) today reported final results from its 2012 drill
program designed to search for high-grade core zones underlying its
very large KSM gold-copper project. The remaining hole at Deep Kerr
provides strong confirmation that the Deep Kerr discovery has the
potential for a very large tonnage of high-grade copper and gold
mineralization; the hole reported long runs of elevated copper
including 22 meters of 0.98%. Drilling also found three more targets
with favorable markers characteristic of core zones (see attached map
at The $15 million
2013 drill program to pursue these targets is expected to begin in
June, 2013. 
World-class gold-copper porphyry districts such as KSM customarily
consist of deeper, magmatic source ores linked upwards through
transitional porphyries and skarn zones hosted by shallow intrusions,
volcanic and sedimentary rocks to vein systems often characterized as
epithermal deposits. The six deposits 
in the area of KSM demonstrate
this vertical evolutionary architecture. All four porphyry zones at
KSM where reserves have been defined are open at depth and exhibit
the alteration mineralogy and textural indicators that suggest links
to a deeper source.  
This year's program used the evidence of temperature and pressure
variances, geochemical markers and deep penetrating geophysical
surveys to vector from known porphyry mineralization towards
potential source areas. A total of 19,813 meters of core drilling was
completed in the 2012 program resulting in: (1) the extraordinary
Deep Kerr discovery (see release of November 8, 2012); (2) discovery
of three more potential high grade zones at McQuillan, Iron Cap and
North Mitchell (see details below); and (3) discovery of an
unexpected epithermal gold deposit at the Camp Zone (see release of
September 5, 2012). Further results are awaited from another 10 holes
from the Camp Zone. 
Seabridge Chairman and CEO Rudi Fronk noted that "when we began our
search for a core zone at KSM, we assumed that the four main deposits
would probably link to one such zone. We now believe that there may
be several deep seated sources. Our first priority is to generate a
high quality resource for Deep Kerr which could have a very
significant economic impact on the KSM project particularly if it
proves to be accessible from the Sulphurets valley floor by way of an
inclined tunnel. Our second priority is to test the deep potential of
the McQuillan and Iron Cap core zone targets which are ideally
located for ease of access and integration into our project design."  
"We are increasingly confident that this core zone program is the
game-changing development we had hoped for. We have demonstrated that
exceptional exploration potential remains within the KSM project and
that we have the geological team to unlock it. Our aim for next year
is to establish KSM as an unparalleled opportunity for the world's
largest mining companies," Fronk said. 
Following is a summary of results from core zone targets with planned
exploration investment in 2013: 
Deep Kerr Target 
Evaluation of the dip projection at Kerr led to the discovery of the
Deep Kerr deposit. Alteration intensity and higher temperature
alteration mineralogy corresponded with a favorable increase in the
chalcopyrite to pyrite ratio down dip of the existing reserve at
Kerr. Additionally, gold-only mineralization in the periphery of the
deep zone increased in thickness and gold and copper grades showed
more complete overlap within the deep zone. The intersections within
the Deep Kerr target returned some of the highest metal values yet
found in the KSM porphyry systems. Results from drill hole K-12-22
reinforced the discovery of Deep Kerr and continue to support a
significant potential resource expansion of high-grade copper and
gold. Note that this hole deviated from the target zone as it began
to penetrate the best grades.

Plans for exploring and defining the Deep Kerr deposit are designed
as a two stage drill program. Initial drilling will concentrate on
establishing roughly 500 meter drill spacing in the target to confirm
the limits of the Deep Kerr zone. Follow-up and off-set drilling of
the better grades holes will then proceed, to reduce drill hole
spacing to a level that would permit meaningful resource estimation.
It is expected that this part of the program will be active
throughout the summer season and employ up to four diamond drills. 
McQuillan Target 
The McQuillan target is a resistivity anomaly down dip of a discrete
magnetic anomaly in the structural panel below the Mitchell Thrust
Fault and within a broad zone of surface alteration and
mineralization. Altered andesite rocks of the Hazelton Group and
coarse grained porphyritic intrusions were encountered throughout
these drill holes. Drill hole MQ-12-03, azimuth 0 degrees and
inclination of -90 degrees, dominantly encountered post mineral
intrusions and likely defines the north-east limit of the potential
core zone. Hole MQ-12-04, azimuth 335 degrees and -55 degrees, cut
altered and mineralized rocks higher in the mineral system. Drill
hole MQ-12-05, azimuth 335 degrees and dip of -55 degrees,
encountered the upper part of the mineral system down to 815.1 meters
where an intense breccia was intercepted that showed progressive
increases in favorable potassium feldspar, biotite and magnetite
alteration and increasing chalcopyrite to pyrite ratios down hole. At
915.3 meters in this hole, drilling conditions deteriorated while
penetrating a normal fault and the hole was terminated. Drill results
from the McQuillan target continue to be evaluated but appear to
confirm a north-west trending deep gold-copper zone.

McQuillan is located under the ridge line between Mitchell Creek and
Sulphurets Creek and below the Sulphurets deposit. This target could
be exploited from a decline in either the Mitchell or Sulphurets
valleys and current plans have placed drainage tunnels in the
vicinity of this target. The potential value of this target is due in
part to its proximity to planned infrastructure. Two drill holes are
planned for early in the 2013 program to fully evaluate the potential
of the McQuillan target. 
Iron Cap Target 
Iron Cap is nearly contiguous with the Mitchell deposit on the east
and the deep potential on this target sits in an attractive position
for quick integration into the project development plan. All the past
drilling on the Iron Cap deposit has demonstrated that alteration
intensity and chalcopyrite concentrations improve with depth. In
addition, the progression of alteration suites shows that higher
temperature environments exist at depth in Iron Cap. One drill hole
was completed on this target in 2012. Hole IC-12-47 encountered
mineralization that supports potential for a high-grade core zone at
depth; however, the hole deviated severely and the target zone was
not intersected.

The proximity to both planned infrastructure and the Mitchell block
cave deposit makes this target a priority. Additional drilling is
planned on the Iron Cap deposit in 2013 to evaluate the potential for
a deep zone under the current reserves. 
North Mitchell Target 
The mineralized and altered intervals beneath the Sulphurets Thrust
Fault intersected by holes M-12-128 and M-12-129 (see release of
September 5, 2012) are interpreted to have intersected the periphery
of a new, blind (or buried) porphyry gold-copper hydrothermal system
at KSM. This target is being called North Mitchell and is represented
by a deep MT low resistivity anomaly between the Mitchell and Iron
Cap deposits. The zone is typified by potassic hornfels in andesite
that is pervasively chlorite altered, with pyrite, magnetite, and
minor but ubiquitous chalcopyrite. These characteristics suggest that
the North Mitchell target is associated with an unknown, very large
and robust mineral system.  
North Mitchell and its well defined MT anomaly are adjacent to the
designed twin Mitchell Access Tunnel which connects the deposits in
Mitchell and Sulphurets valleys with the planned Tailings Management
Facility. The proximity of this target to designed infrastructure
would likely enhance the value of the project. Consequently, this
target remains a priority for additional drilling in 2013. 
National Instrument 43-101 Disclosure. 
Exploration activities at KSM are being conducted by Seabridge
personnel under the supervision of William E. Threlkeld PGeo., Senior
Vice President of Seabridge and a Qualified Person as defined by
National Instrument 43-101. Mr. Threlkeld has reviewed and approved
this news release. An ongoing and rigorous quality control/quality
assurance protocol was employed during the 2012 program including
blank and reference standards in every batch of assays. Cross-check
analyses were conducted at a second external laboratory on 10% of the
samples. Samples were assayed using fire assay atomic adsorption
methods for gold, and ICP methods with atomic adsorption on
concentrations over detection limits for other elements.  
This initial drilling on deep core zone targets is orientated to
optimize the depth penetration and to intersect the identified
targets. Insufficient information is available on the orientation of
these targets consequently it is not known if these drill
intersection represent true widths of mineralized zones. 
Seabridge holds a 100% interest in several North American gold
projects. The Company's principal assets are the KSM property located
near Stewart, British Columbia, Canada and the Courageous Lake gold
project located in Canada's Northwest Territories. For a breakdown of
Seabridge's mineral reserves and mineral resources by category please
