18.09.2013 | The Newswire
Vancouver, B.C., September 18, 2013; West Cirque Resources Ltd. (WCQ: TSX.V) has completed its 2013 field program on the Castle Copper-Gold-Silver (Cu-Au-Ag) 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, 2013Drill Highlights
CA13-01 100 meters of 0.35 % Cu Eq*
CA13-03 108 meters of 0.43 % Cu Eq*
Including 32 meters of 0.96 % Cu Eq*
Castle West
Phase II drilling at Castle West (under option from Bearclaw Capital Corp.; see news release of January 4, 2012) consisted of four drill holes which tested the western part of the porphyry system over a strike length of 800 meters:

-----------------------------------------------------
Drill holes CA13-01 and CA13-02 targeted a 600 by 250 meter coincident magnetic and chargeability high outlined in 2012. Both drill holes intersected significant intervals of monzodiorite porphyry with strong potassic (K-feldspar-magnetite) alteration and quartz-magnetite-chalcopyrite veining. Widespread copper and gold values include:
-CA13-01 - 0.10% Cu and 0.28 grams per tonne (g/t) Au over 274 meters (14-274 meters), including 0.12% Cu and 0.40 g/t Au over 52 meters (140-192 meters), and
-CA13-02 - 0.11% Cu and 0.36 g/t Au over 36 meters (58-94 meters).
CA13-01 also intersected a deeper Cu-Au zone associated with potassic alteration (0.15% Cu and 0.41 g/t Au over 26 meters, 456-482) near the bottom of the hole.
CA13-03 stepped out 300 meters southeast of CA13-02, targeting the western edge of a 200 by 600 meter magnetic low which is also coincident with the chargeability high. Phase I drill hole CA12-05 previously tested the northwest side of this mag low, intersecting significant gold and copper-gold mineralization, including 1.02 g/t Au over 34 meters (70-104) and 0.10% Cu and 0.45 g/t Au over 20 meters (210-230). CA13-03 resulted in the discovery of higher grade Cu-Au-Ag mineralization associated with strong phyllic alteration and polyphase quartz-chalcopyrite-pyrite veining. This includes two intervals:
-2.14% Cu, 4.88 g/t Au and 73.2 g/t Ag over 4 meters (154-158), and
-0.13% Cu, 1.28 g/t Au, 2.2 g/t Ag over 32 meters (308-340), including 0.40% Cu, 3.83 g/t Au, and 11.1 g/t Ag over 4 meters (314-318).
Overall the lower interval is in a broader zone of strongly elevated gold and copper (e.g. 0.53 g/t Au and 0.08% Cu over 108 meters, 232-340) which contains widespread early quartz-magnetite veining and a variable magnetite destructive phyllic overprint. Orientation and true thickness of the higher grade sections is unknown because of the wide drill hole spacing, but higher grade sulfide rich veins are commonly oriented at 20-50 degrees to the core axis.
CA13-04 stepped out 230 meters northwest of CA12-02 to test the western limits of the porphyry system. Together with CA12-01 the drill hole limits the system near the west side of the Castle West property to relatively narrow mineralized intervals (e.g. 0.13% Cu, 0.75 g/t Au over 10 meters, 238-248).
The Castle porphyry system is open to the east, as the easternmost drill holes CA12-05 and CA13-03 contain the highest grade gold and copper intersected to date, with individual 1 meter assays up to 10.15 g/t Au and 5.0% Cu. The intense phyllic alteration and sulfide veining in these holes is associated with a coincident magnetic low and chargeability high which remains untested over 800 meters of strike length between CA12-05 and the copper-rich Nichol Zone (see news release November 28, 2012). Although much of this target area is covered by volcanics and extensive talus, rock grab and chip samples have returned the following values:
-M458591 - 0.91 g/t Au, 11.1 g/t Ag, 14 ppm Cu (intense silica-pyrite alteration)
-J486095 - 3.69 g/t Au, 2.4 g/t Ag, 0.07% Cu (quartz-limonite stockwork in lapilli tuff)
-M458593 - 10.75 g/t Au, 17.7 g/t Ag, 0.26% Cu (sintery quartz, limonite boxwork cut by clear quartz veinlets)
-39.6 g/t Au, 3.4 g/t Ag and 0.08% Cu over 0.4 meters (Teck, 1987)
-4.8 g/t Au, 5.8 g/t Ag and 0.11% Cu over 0.6 meters (Teck, 1987)
-5.8 g/t Au, 16.5 g/t Ag and 0.27% Cu (Teck, 1987)
Castle East
Reconnaissance mapping on West Cirque's 100% owned Castle East property has outlined an outcropping zone of altered monzodiorite to monzonite porphyry at least 600 meters in strike length near the valley bottom. Many of the porphyry outcrops have undergone intense quartz-sericite-pyrite (QSP) alteration which represents the eastern extension of the phyllic zone on the west side of the ridge, discussed above. Limited rock sampling from this zone returned the following anomalous values:
-M458618 - 0.72 g/t Au, 1.6 g/t Ag, 66 ppm Cu (strong silica-pyrite to QSP alteration)
-M458619 - 0.08 g/t Au, 1.0 g/t Ag, 848 ppm Cu (chlorite-pyrite to silica-pyrite altered monzonite, 3% clotty pyrite, trace chalcopyrite)
-M458620 - 0.07 g/t Au, 0.4 g/t Ag, 1300 ppm Cu (quartz-calcite-pyrite-chalcopyrite veins, intense chlorite-calcite-pyrite altered volcanics)
-M458623 - 1.24 g/t Au, 1.2 g/t Ag, 390 ppm Cu (green chlorite-sericite-pyrite-calcite altered monzonite, calcite veinlets, pyrite-chalcopyrite stringers and disseminated)
The presence of strong, widespread porphyry style alteration associated with strongly anomalous copper and gold values represents a significant untested target at Castle East.
The 1034 hectare Castle project comprises two properties, the 431 hectare, 100% West Cirque owned Castle East property, and the 603 hectare Castle West property under option from Bearclaw Capital Corp. The Castle project is 10 kilometers west of Highway 37 and 68 kilometers south of Dease Lake. The Castle porphyry system is located in the prolific Triassic-Jurassic Northern Stikine porphyry belt, 25 kilometers northwest of the Imperial Metals' Red Chris copper-gold deposit, 17 kilometers north of the GJ copper-gold porphyry and 15 kilometres west of Colorado Resources' North Rok discovery.
The Castle program is being funded by Freeport-McMoRan of Canada Limited ("Freeport"), a wholly owned, indirect subsidiary of Freeport-McMoRan Copper & Gold Inc., as part of an Earn-In Agreement to explore West Cirque's Castle, Tanzilla and Pliny properties in northwestern British Columbia. Freeport can earn an initial 51% interest in the Properties by funding cumulative expenditures of $8,000,000 over a four-year period, including $1,500,000 of Mandatory Expenditures in the first 18 months. West Cirque is the operator under the agreement for the 2013 program.
Core samples were prepared at West Cirque's core logging facility in Iskut, B.C. and 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, molybdenum and silver by ICP-AES using an aqua regia digestion. Blanks, standards and duplicate samples were inserted into the sample sequence with a ratio of approximately one sample out of twenty-five. The 2013 drilling program and sampling protocol was supervised by John Bradford, M.Sc., P.Geo.
Historical assays cited above should not be relied on even though they have been compiled from sources believed to be reliable. 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 approved by John Bradford, M.Sc., P.Geo. and V.P. Exploration and Director for West Cirque Resources, who serves as a Qualified Person under the definition of National Instrument 43-101.
