Corvus Gold Inc. Intersects Copper and Gold Mineralization in First Drill Holes in the POW Target, Chisna Project, Alaska
Highlights include: 23 metres of 0.38% Copper, 0.43 g/t Gold and 7.5 g/t Silver
(including 2.1 metres @ 1.7 g/t gold, 4.4% copper and 21.8 g/t silver)
September 30, 2010
Vancouver, B.C........Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR) is pleased to announce successful results from the Phase 1 diamond drill program at the Chisna Project located in the Chistochina Mining District of south-central Alaska, 350 kilometres northeast of the city of Anchorage by paved highway.
The Summer 2010 exploration program, which included 2,926 metres (9600 feet) of diamond drilling, has successfully identified a large number of copper-gold targets, two of which were drill tested as part of the Phase 1 drill program. This work has identified several styles of mineralization within the nearly 10,000 square kilometre Chisna land package, including porphyry copper-gold-molybdenum, skarn copper-iron and copper-gold targets as well as structurally controlled gold-copper mineralization.
Assays from one of the three drill holes into the POW target (PW-10-02) returned 23 metres of 0.38% copper, 0.43 g/t gold and 7.5 g/t silver, including 2.1 metres @ 1.7 g/t gold, 4.4% copper and 21.8 g/t silver. The first drill hole (POW-10-01) returned an oxidized and variably faulted interval over 23.8 meters of 0.13% copper, 0.16 g/t gold and 2.8 g/t silver. The third hole was lost in a fault zone prior to reaching the target mineralization.

The POW target is just one of several copper occurrences in the northern area of the Chisna project, which covers approximately 36 square kilometres (Figure 1). Surface sampling conducted in 2010 has greatly expanded the area of known mineralization and, together with the POW shallow drill results, has highlighted the potential of this large and well mineralized area. Copper mineralization styles include veins, breccias and disseminated mineralization which are related to large under explored alteration systems. In this area copper-gold mineralization is associated with pyrite, magnetite, specular hematite and jasper suggesting that the system is oxidized, a favourable characteristic of large copper and gold mineral systems. The POW target area also contains numerous historical placer gold mining sites, which are estimated to have produced in excess of 200,000 oz of gold since the late 1800's.

The Grubstake target is a porphyry copper-gold system and is one of 4 priority targets in the southern part of the Chisna belt. At Grubstake copper-gold mineralization is associated with chalcopyrite stockwork veining within extensive potassic and sodic-calcic alteration zones that are exposed in outcrops and in drill holes. The Grubstake target has characteristic zoned alteration out from the potassic core areas, which includes gold bearing actinolite-magnetite veining. The area of anomalous gold and copper in soils covers more than 7.5 square kilometres. A 3D induced polarization survey, consisting of 53.6 line kilometres, was conducted over the central Grubstake target and identified a series of targets (Figure 2) of which 4 have been tested with one or more holes. All Grubstake assay results are pending, however, holes GS-10-01 and GS-10-03 encountered significant intervals of potassic alteration and chalcopyrite mineralization.

"Our primary objective during the Summer 2010 work program at Chisna was to indentify copper-gold porphyry mineralization at a number of targets," stated Russell Myers, President. "After we have reviewed the data gathered over the past year, we anticipate developing a targeted follow-up exploration program focusing on our highest priority targets for 2011. Furthermore, we are extremely fortunate to have had such excellent support from the Ahtna Corporation and the local communities in the region which enabled us to complete such a successful initial program."
About the Chisna Project
The Chisna Project is focussed on a new and emerging Alaskan copper-gold porphyry belt of deposits with copper and gold mineralization associated with mid-Cretaceous intrusions of similar age and style to the Pebble deposit to the west and Orange Hill deposit to the east (Figure 3). At present, the Corvus/Ocean Park joint venture controls over 232,000 acres of either State of Alaska Mining Claims or land leased from Ahtna Corporation. The 2010 exploration program represents the first modern exploration and drilling to take place on this large and highly mineralized new Alaskan porphyry belt.

Corvus and its predecessor-in-title, International Tower Hill Mines Ltd., began exploration on the project in 2006 and discovered the Grubstake porphyry copper system in 2007. Beginning in 2010, the Chisna project is being operated as a joint venture between Raven Gold Alaska Inc. (a subsidiary of Corvus) and Ocean Park Alaska Corp. (a subsidiary of Ocean Park Ventures Corp.), with Ocean Park earning 51% by contributing USD 20 million in exploration expenditures over a 5 year period, thereby providing Corvus with a no cost assessment of this belt (see International Tower Hill Mines Ltd. news release NR09-29 for details on the terms of the joint venture). Raven is the operator of the joint venture during the first two years.
In 2010, the Chisna project advanced dramatically with the completion of a large airborne geophysics survey (6700 line kilometres of ZTEM (Z Axis Tipper Electromagnetic system), an innovative airborne EM system credited with correctly delineating the Pebble deposit) and extensive ground geophysics (100 line kilometres of 3D induced polarization) together with surface prospecting and drilling. The POW drilling represents a small portion of the Summer 2010 drilling program, with the results from the drilling conducted on the main Grubstake target pending.
