West Cirque Discovers High Grade Cu-Au-Ag Zones, Heath Project
24.09.2013 | The Newswire
Vancouver, B.C., September 24, 2013; West Cirque Resources Ltd. (WCQ: TSX.V) discovered two new zones of high grade copper-gold-silver (Cu-Au-Ag) mineralization during a recent mapping and rock sampling program at its 100% owned Heath Copper-Gold Porphyry project in central B.C.Mapping and rock sampling carried out in September 2013 documented widespread potassic (biotite-magnetite and K-feldspar) and sodic (albite) alteration and veining associated with chalcopyrite mineralization. Two new mineralized zones were discovered, assaying up to 7.7% Cu, 2.33 grams per tonne (g/t) Au and 78.5 g/t Ag.
A Zone
The historic A Zone is a northwest trending mineralized structure containing locally brecciated layers of magnetite-chalcopyrite, biotite-magnetite- chalcopyrite, semi-massive chalcopyrite-quartz, chlorite/biotite altered diorite and biotite altered diorite with up to 15% disseminated pyrite. Three rock samples from the zone averaged 0.71% Cu, 0.38 g/t Au and 19 g/t Ag (Au assays in the table are in ppb or parts per billion):
----------------------------------------
|Sample | |Au ppb|Ag g/t|Cu % |

|Q724962|chip 1m |892 |43.5 |0.888|

----------------------------------------
In 2001 three shallow (13, 20 and 24 meter) packsack drill holes were collared beside the A Zone trenches and intersected multiple intervals of mineralization, including intervals not exposed in the trenches. Sampled intervals included 3.15% Cu, 0.36 g/t Au and 22.6 g/t Ag over 1.52 meters (HEX01-01, 17.09-18.59), 1.02% Cu, 0.19 g/t Au and 9.1 g/t Ag over 3.05 meters (HEX01-02, 2.44-5.49) and 1.52% Cu, 0.32 g/t Au and 14.8 g/t Ag over 1.52 meters (HEX01-03, 3.96-5.49).
A newly discovered mineralized zone about 180 meters southwest of the historic A Zone trenches was sampled over a strike length of 80 meters. Coarse grained, locally pegmatitic biotite-magnetite altered diorite is cut by biotite-chalcopyrite, quartz-epidote and albite veins. Both disseminated and poddy vein and shear-hosted chalcopyrite are present, and the wallrock contains up to 10% disseminated pyrite. Four rock samples from the zone averaged 2.51% Cu, 0.79 g/t Au and 34 g/t Ag:
-------------------------------------
|Sample |Type |Au ppb|Ag g/t|Cu % |

|-----------------------------------|
|Q724965|grab |52 |0.9 |0.242|
-------------------------------------
Central Zone
The Central Zone is an area of limited outcrop and relatively flat topography extending over a strike length of at least 1.7 kilometers and a width of 0.5 kilometers. It is near the center of a large (2.4 by 2.0 kilometer) copper in soil anomaly outlined by Teck in 1990. The Central Zone has not been tested by drilling. Diorite near the historic Trench C showing near the core of the zone is strongly carbonate altered and cut by quartz and calcite veins with chalcopyrite (Q724968). About 80 meters to the east, an old cat track exposes subcropping boulders of magnetite, chalcopyrite and trace bornite (Q724969) and K-feldspar veined diorite with disseminated chalcopyrite and minor biotite (Q724970). Three rock samples from this zone average 1.13% Cu, 0.071 g/t Au and 3.2 g/t Ag:
----------------------------------
|Sample | |Au ppb|Ag g/t|Cu % |
|--------------------------------|
|Q724969|grab|12 |7.1 |1.735|

|Q724969|grab|22 |2.1 |1.520|
|--------------------------------|
|Q724970|grab|179 |0.5 |0.126|
----------------------------------
East Zone
The East Zone is a newly delineated zone of mineralization centered about 600 meters southeast of Trench C. Mineralization outcrops sporadically across a width of at least 225 meters within a 300 by 400 meter part of the soil anomaly which contains numerous values over 1000 ppm Cu (up to 3671 ppm). Mineralization consists of sheeted magnetite-quartz-chalcopyrite, biotite-K-feldspar-magnetite-chalcopyrite and quartz-epidote-chalcopyrite veins. Four rock samples from the zone averaged 1.15% Cu, 0.19 g/t Au and 27.8 g/t Ag:

Steve Vanry, West Cirque's President and CEO comments: "The high grade nature of the mineralization and the discovery of new mineralized zones during a small reconnissance scale program attests to the considerable exploration upside at Heath. It also supports the assessment of our technical team that Heath represents a significant underexplored and undervalued asset in West Cirque's porphyry copper-gold portfolio".
The Heath project covers an area of 1419 hectares. The road accessible project is located 108 kilometers northwest of Fort St. James in central B.C. The property is in the Hogem Batholith in the prolific Quesnel Trough, 30 kilometers south of the Kwanika deposit (142 million tonnes of 0.31% Cu and 0.29 grams per tonne Au indicated resource) and 74 kilometers northwest of the Thompson Creek Metals' Mount Milligan project (482 million tonnes of 0.20% Cu and 0.39 grams per tonne Au proven and probable reserve). Mount Milligan is expected to reach full commercial production in 2014 and has a forecast mine life of 22 years (www.mtmilligan.com).
Rock samples were analyzed at ALS Minerals' 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. 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.
