Seabridge Gold Inc. (TSX:SEA)(NYSE Amex:SA) -
New drilling results have confirmed a significant expansion of
Zone 8 within Courageous Lake's multi-million ounce FAT deposit.
Previous drilling on the relatively high-grade Zone 8 had generated
only a small portion of the FAT deposit's measured and indicated
resource.
"We are excited by the new data from Zone 8 which has proved to
be much more continuous than previously thought. These results
could more than quadruple Zone 8's contribution to measured and
indicated resources and help to increase the deposit's average
grade. It's also important to note that most of this expansion is
within the existing pit design and will therefore convert waste to
resources which may qualify for reserves in the Preliminary
Feasibility Study now in progress. We are also intrigued that this
zone extends beyond the designed pit and therefore represents a
priority exploration target for next year," said Seabridge
President and CEO Rudi Fronk. An updated NI-43-101 compliant
resource estimate is now in progress and should be released within
45 days.
Assay results of the fourth and final batch of infill holes
drilled this year at Courageous Lake are as follows:

Note: All assays have been capped at 10.1 grams of gold per
tonne (g/T). True thicknesses of the above reported drill hole
intercepts are estimated to be approximately 85-90% of the reported
interval. Intercepts in bold in the table above are from Zone 8.
Hole CL-175 was drilled on a new target and CL-177 to CL-180 were
drilled as condemnation holes.
The drilling component of this year's $16 million program at
Courageous Lake, located in Canada's Northwest Territories, was
designed to: (i) upgrade inferred resources within the current FAT
deposit pit plan by infill drilling; (ii) complete geotechnical
drilling required for pit slope and water management planning in
the PFS; (iii) condemn areas where project facilities will be
located; and (iv) look for new targets along the 53 kilometers of
the Matthew's Lake greenstone belt held by Seabridge.
In August, September and November Seabridge reported results
from the first 36 core holes (totaling 11,680 meters) from this
summer's program. The results reported above represent the final
assays from the 2011 infill drill program. All 48 infill holes
drilled on the FAT deposit in 2011 intersected gold values above
the resource cutoff grade.

The FAT deposit is in the Slave Province, an extensive
geological terrain in Canada's Northwest Territories. The deposit's
name is an acronym for its dominant rock type, Felsic Ash Tuff.
This gold occurrence, hosted by Archean greenstone rocks, was
formed in a rhyolite/dacite dome complex that measures about 2km
along strike and about 800m of stratigraphic section in width.
Although tuffaceous rocks are the most common in the deposit there
are also clear intervals of clastic and chemical sedimentary rocks
and a few late intrusions.
Sulfide mineralogy in the FAT deposit is relatively simple and
consists of pyrite, pyrrhotite, arsenopyrite, sphalerite, and
chalcopyrite in decreasing order of abundance. While all of these
minerals can be found in the mineralized zones, only arsenopyrite
has a consistent correlative relationship to gold concentrations.
Extensive metallurgical test work has been performed on Courageous
Lake resulting in an expected gold recovery of approximately 90%
utilizing a flotation circuit followed by pressure oxidation. In
June, 2011 Seabridge announced the results of a Preliminary
Economic Assessment ("PEA") for Courageous Lake demonstrating the
potential for a robust project in the current gold price
environment (see
http://www.seabridgegold.net/CL-PEA_ExecSummary2011.pdf for the PEA
executive summary).
In constructing a geological model for resource estimation,
unique stratigraphic intervals were defined and labeled as domains
1 through 9 and domain 14. Each domain contains specific and unique
tuff and sedimentary units arranged in particular stratigraphic
sequences. The defined geological domains are relics of the
depositional environment in which they were formed. Consequently,
within these domains the style of rock types, hydrothermal
alteration, vein occurrences and sulfide mineralogy are generally
consistent across the length and breadth of each specific domain.
Distribution of gold within a domain and the surrounding rock is
treated differently from other domains in resource modeling.
Although 10 separate geological domains have been recognized in the
FAT deposit, domains 3, 4 and 5 currently contain about 90% of the
gold in the deposit.
Descriptions of the above reported holes are as follows:
CL-165: Oriented to the east and drilled on the west side of the
deposit at -55 degrees, this hole was designed to test zone 8.
Lithologies are characteristic of zone 8 with felsic tuffs followed
by volcanic sedimentary units. Silicic and sericite alteration are
present in varying abundance within the felsic units.
Mineralization was intercepted at roughly the correct horizon with
grades in line with expectations. The mineralized width was in line
with expectations and this hole should upgrade inferred
resources.
CL-166: Collared on the west side of FAT and drilled to the west
at an inclination of -55 degrees, this hole was designed to test
zone 8 up dip of previous drill holes. A combination of felsic tuff
and mixed sedimentary units were intercepted. Alteration included
carbonate and sericite, mostly in the felsic units. An unpredicted
intercept in zone 14, up section from zone 8 returned typical grade
for that zone. The intercepts in zone 8 were in the proper
location, and of roughly the predicted widths, but slightly lower
grades than would have been anticipated. Inferred resources will be
upgrade in classification and some new resources added by this
hole.
CL-167: Located on the far western edge of the deposit and
drilled at an inclination of -50 degrees back to the east, this
hole was designed to upgrade inferred resource blocks in zone 8.
The dominant lithologies encountered are felsic ash tuff passing
into volcanic sedimentary units down hole. Alteration types are
carbonate and sericite with mineralization consistent with model
predictions for this section. The results will convert inferred
resources to indicated resources.
CL-168: Drilled from west to east and located on the far western
side of FAT, this hole was drilled at -50 degrees and designed to
test zone 8 on a section where there was no previous drilling. The
lithologies cut in this hole are consistent with the model, felsic
tuff in the upper part, changing over to volcanic sedimentary units
at depth. Alteration types are carbonates, sericite and silicic, in
decreasing abundance. The mineralized interval contained better
grades at comparable widths to those on adjacent sections. Results
from this drill hole have increased the resources on zone 8.
CL-169: Oriented to the west at an inclination of -55 degrees
and located in the western part of the deposit, the hole was
designed to fill a gap and upgrade inferred blocks in zone 8.
Lithologies encountered in this hole are typical tuff and mixed
volcanic sedimentary units. Carbonate is the dominant alteration
type with lesser sericite and silica. The interval intercepted in
zone 14 was not predicted, but is consistent with other intercepts
in the zone. In zone 7 the interval was narrower than expected, but
grades were consistent with the model. The two mineralized
intercepts in zone 8 are consistent with model predictions and
should lead to inferred resources being upgraded.
CL-170: Drilled at the northern end of FAT and oriented to the
west at -51 degrees, this hole was designed to test zone 3 and
upgrade inferred blocks in zone 4. Felsic ash tuff with variable
lapilli-size clast content comprises the bulk of the lithologies
encountered. Abundant carbonate alteration is accompanied by patchy
sericite and silica. Zone 3 continues to show a narrow erratic
nature consistent with the predicted termination of this domain to
the north. The widths of intercepts in zone 4 are as predicted by
the model, but at slightly better grades. Inferred resource blocks
around this hole are expected to be upgraded to the indicated
category.
CL-171: Located on the west side of deposit, with an easterly
orientation and inclination of -45 degrees, the hole was designed
to upgrade inferred blocks near the surface in zone 8. Lithologies
were comprised of felsic tuff and volcanic sedimentary rocks.
Carbonate is the most dominant alteration with lesser sericite and
silica. Mineralization was consistent with model predictions for
both grades and width, and will upgrade inferred resources to
higher categories.
CL-172: Collared in the north central part of the deposit and
drilled at -47 degrees to the west, this hole was designed to
upgrade inferred resources in zone 4. This hole intersected felsic
ash and lithic tuff, with pervasive carbonate alteration. Locally,
vein-controlled sericite and silicic alteration is recognized. The
mineralization cut in zone 4 is consistent with model predictions
and will upgrade the classification of resources.
CL-173: A shallow hole drilled to the east at an inclination of
-45 degrees and located on the west side of FAT, it targeted near
surface inferred blocks in zone 8. The hole passes from felsic
volcanic rocks into alternating volcanic sedimentary and volcanic
rocks with gradational contacts and ends in sedimentary rock units.
Carbonate alteration dominates the upper parts of the hole with
minor sericite, while silicic alteration is most common at depth.
Mineralization was intercepted at the anticipated depth, with the
width of the zone as the model predicted, but grades are below
expectations. Inferred resources around the hole will be upgraded
on this section.
CL-174: Drilled to the west at -55 degrees and located in north
central FAT, this hole was designed to upgrade the classification
of inferred blocks in zones 3 and 4. Lithologies intersected were
predominantly felsic tuff. Carbonate alteration characterizes this
drill hole with less abundant chlorite and patchy sericite
intervals. Mineralization in zone 3 is consistent with model
predictions, and should upgrade those blocks to the indicated
category. A broad section of low-grade was anticipated in zone 4,
but that intercept was narrower and below cut-off grade in this
drill hole.
CL-176: Located at the northern end of the deposit and drilled
to the east at -50 degrees, this hole was designed to upgrade
inferred resources in zone 4. Drilling encountered felsic tuff
dominated by ash-rich sections and minor lapilli fragments. Minor
silicic alteration was present throughout, sericite alteration is
not intense and only locally present. The mineralized interval
contained gold grades as predicted by the model, but the interval
was narrower than predicted.
CL-181: Located on the east side and drilled to the east with a
-45 degrees inclination, this hole targeted near surface inferred
resources in zone 2. Felsic ash tuff is the dominant lithology with
sections of coarse lithic tuff. Alteration is not intense and is
comprised of alternating sericite and carbonate alteration styles
with local intervals of silicic and chlorite alteration. A broad
zone of low-grade mineralization was intercepted at the correct
interval, confirming the geology and inconsistent mineralization in
zone 2.
