Corvus Gold gains 100% control of Chisna Project, Alaska identifies new copper porphyry discovery at west green target

VANCOUVER, Nov. 7, 2012 /PRNewswire/ - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR; OTCQX: CORVF) announces that follow up mapping and sampling at the Chisna Project during the summer of 2012 identified a new porphyry copper system at the West Green target.  This new discovery is the second major porphyry system to be identified in the southern part of the 965 km2 Chisna Project area, underscoring the potential of this underexplored area of Alaska.  Corvus' Chisna Project joint venture partner, Ocean Park Ventures Corp. ("OCP"), has withdrawn from the joint venture and thereby returned 100% of the project to Corvus.  Corvus understands that OCP has expended approximately $11M in exploration on the Chisna Project over the past 3 years.

Jeffrey Pontius, Corvus CEO, stated, "The new exploration results on the Chisna Project have confirmed our belief in the potential of this area of Alaska to host world class copper-gold porphyry systems.  The scale and grade of the systems that has been discovered to date is very encouraging and we look forward to the next phase of exploration."

West Green - Jolly Green Targets

Ridge and spur soil sampling conducted in 2011 revealed significant copper, gold, molybdenum and tungsten anomalies in an area immediately north of a major regional shear zone in the Golden Range target area (Figure 1). Follow-up exploration during 2011 revealed an area of extensive copper staining, high-grade gold, silver, copper and molybdenum mineralization with up to 126 g/t gold, 198 g/t silver, 17% copper and 0.13% molybdenum at the Jolly Green target on the north side of the prominent ridge that runs through the area (Figure 2).

In 2012, the West Green and Jolly Green soil anomalies were followed up with prospecting and mapping. This work indicates that the mineralization in both areas is related to NNW trending structures that terminate in a regional shear to the south. The high-grade structurally controlled copper mineralization at Jolly Green has now been shown to continue for over 700 metres of strike and is related to the West Green target. The mineralization at West Green is typical porphyry copper style mineralization with sheeted veins and vein stockworks as well as chalcopyrite veinlets and disseminations in a strongly potassic altered quartz diorite porphyry surrounded by broad propylitic alteration zone. This newly discovered potassic altered porphyry core zone is associated with weak magnetite mineralization, which has now highlighted a magnetic anomaly 500 metres west of the currently mapped potassic zone, thus significantly enlarging the target.

About the Chisna Project

The Chisna Project is focused on a new and emerging Alaskan gold and copper-gold porphyry belt of deposits with copper and gold mineralization associated with mid-Cretaceous intrusions of similar age to the Pebble deposit to the west and Orange Hill deposit to the east. At present, the Chisna Project consists of approximately 232,000 acres of State of Alaska mining claims and fee land leased from Ahtna Corporation.  The Chisna property has good infrastructure, as it sits between two major highways and has access to grid power as well as an extensive winter road network, making this a unique potential development setting in Alaska.
