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.

Exploration and Director for West Cirque Resources, who serves as a Qualified Person under the definition of National Instrument 43-101.
