West Cirque Extends Footprint of Porphyry Mineralization at Pliny

Vancouver, B.C., October 15, 2013; West Cirque
Resources Ltd. (WCQ: TSX.V) has completed the
2013 field program on its 100% owned Pliny Copper-Gold (Cu-Au)
porphyry project, northwestern B.C. Exploration was funded by
Freeport-McMoRan of Canada Limited as part of an Earn-In Agreement
announced on March 4, 2013. West Cirque was the operator of the
exploration program in 2013.
A soil
sampling survey was carried out at Pliny in order to better define
the limits and possible extensions of a zone of quartz-chalcopyrite
mineralization discovered in 2011 (see news release August 10,
2011). The Pliny mineralized zone has been traced for 325 meters
and contains locally high grade (up to 8.65% copper and 5.23 grams
per tonne gold from grab samples) copper-gold mineralization
associated with quartz veins and stockworks. Mineralization is
controlled by a northeast trending fault that cuts a polyphase
intrusive complex (diorite porphyry, monzonite, syenite, and
intrusive breccia) with alkalic affinities. The Pliny zone is
centered on a 2.5 by 1.5 kilometer magnetic high which reflects
widespread magnetite veining. Alteration associated with the veins
and stockworks consists of chlorite, tourmaline, magnetite,
actinolite and calcite, as well as specular hematite
veining.
The soil survey
consisted of 148 B horizon samples collected on 200 meter spaced
lines on a 1.2 by 1.4 kilometer grid. The survey outlined two
significant copper anomalies.
Anomaly A is located 400
meters southeast of the Pliny mineralized zone. The anomaly, as
defined by copper values greater than 140 parts per million (ppm),
extends over 200 by 450 meters, open to the south, with copper
values up to 460 ppm. The anomaly is coincident with a magnetic low
and chargeability high (also open to the south), and is located
near the eastern margin of a diorite porphyry stock where it
intrudes Stuhini Group mafic volcanic rocks. Outcrops of intrusive
breccia cut by chlorite-magnetite stringers and containing strong
pyrite occur within the anomaly, and float of diorite porphyry cut
by quartz-carbonate stringers with chalcopyrite blebs is found
downhill.
Anomaly B is 325 by 1100
meters, open to the west, north and south, and contains copper
values to 1500 ppm. The Pliny mineralized structure partly
coincides with the east side of the anomaly, which extends the
potential strike length of the zone another 950 meters southwest of
outcropping mineralization.
In addition to the soil
survey, mapping located a parallel northeast trending mineralized
structure about 450 meters east of the main Pliny fault. About 850
meters northeast of the Pliny zone in a creek gulley, float of
diorite porphyry with K-feldspar-magnetite veining as well as
secondary biotite and actinolite was discovered along with
quartz-chalcopyrite vein float similar to the Pliny zone. More
prospecting and mapping is needed to define the limits and
potential of this zone.
Steve Vanry, West
Cirque's President and CEO comments: "Exploration at Pliny
continues to expand the footprint of both structurally controlled
quartz-chalcopyrite vein and porphyry style alteration and
mineralization. Pliny represents a significant untested alkalic
porphyry target in one of British Columbia's most active and
exciting porphyry belts."
The Pliny property
consists of mineral claims totalling 3407 hectares located 17
kilometers south of Dease Lake and four kilometers west of Highway
37. Pliny is located in the Northern Stikine porphyry belt about 58
kilometers north of Imperial Metals' Red Chris project.
Soil
samples were collected using a standard B horizon sampling
technique, with attention paid to maintaining consistency in sample
media. Samples were shipped to ALS Minerals' preparation lab in
Terrace, B.C. Samples were analyzed at ALS's ISO 9001:2008
certified North Vancouver laboratory for gold by fire assay and
ICP-AES, and for 35 elements including copper by ICP-AES using an
aqua regia digestion. The 2013 soil sampling survey was supervised
by Nigel Luckman, BASc.
Grab
samples are likely to be representative of higher grade material
and no inference can be made of the average grade of a larger
volume of rock. West Cirque's disclosure of a technical or
scientific nature in this news release has been reviewed and

Director for West Cirque Resources, who serves as a Qualified
