Corvus Gold Begins Aggressive 20,000 Metre 2013 Drill Program at the North Bullfrog Project, Nevada
May 7, 2013
Vancouver, B.C……..Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX: CORVF) announces the start of its first phase, 20,000 metre, 2013 North Area drill program at the North Bullfrog Project, Nevada (Figure 1). The program will utilize core drilling to follow-up on high-grade and stockwork vein systems in the Yellow Jacket Zone, a Reverse Circulation (RC) drill program designed to expand the bulk tonnage resource focusing on recent higher grade zones and a water well rig to complete the environmental baseline monitor well network for future permitting activities.
As outlined in the 2013 exploration program announced on April 9, 2013 (NR13-10), drilling will focus on:
the expansion of the recently discovered Yellow Jacket zone and other associate structural zones to determine size and shape of the high-grade gold and silver mineralization. Previous results in this zone included:
- NB 12-138, 72.4m of 1.74 g/t Au & 98.7 g/t Ag including 4.3m of 20.0 g/t Au & 1,519 g/t Ag
NB 12-183, 71.6m of 1.40 g/t Au & 28.9 g/t Ag including 8.9m of 5.4 g/t Au & 129 g/t Ag
the expansion potential of a recently discovered higher grade, potential starter pit targets north and to the west of the currently defined Sierra Blanca deposit. Previous results in this area included:
- NB-12-117, 51.8m of 0.80 g/t Au located west of the existing Sierra Blanca resource
- NB-12-118, 45.7m of 0.56 g/t Au located northwest of the existing Sierra Blanca resource
- NB-12-119, 48.8m of 0.50 g/t Au located north of the existing Sierra Blanca resource
- NB-12-123, 139m of 0.27 g/t Au located north of the existing Jolly Jane resource
Jeff Pontius, Chief Executive Officer, states: “We are very excited to begin our follow-up drilling at our new discoveries at the North Bullfrog project. Our new Yellow Jacket zone is of particular interest as it represents a new Nevada high-grade gold and silver discovery. The potential starter pit targets offer potential to add substantial early mining ounces to the already +1M ounce gold oxide resource, further enhancing the North Bullfrog mining project.”
About the North Bullfrog Project, Nevada
Corvus controls 100% of its North Bullfrog Project, which covers approximately 68 km² in southern Nevada just north of the historic Bullfrog gold mine formerly operated by Barrick Gold Corporation. The property package is made up of a number of leased patented federal mining claims and 758 federal unpatented mining claims. The project has excellent infrastructure, being adjacent to a major highway and power corridor. The Company’s independent consultants completed a robust positive Preliminary Economic Assessment on the existing resource in December 2012.
The project currently includes numerous prospective gold targets with four (Mayflower, Sierra Blanca, Jolly Jane and Connection) containing an estimated Indicated Resource of 15 Mt at an average grade of 0.37 g/t gold for 182,577 ounces of gold and an Inferred Resource of 156 Mt at 0.28 g/t gold for 1,410,096 ounces of gold (both at a 0.2 g/t cutoff), with appreciable silver credits. Mineralization occurs in two primary forms: (1) broad stratabound bulk-tonnage gold zones such as the Sierra Blanca and Jolly Jane systems; and (2) moderately thick zones of high-grade gold and silver mineralization hosted in structural feeder zones with breccias and quartz-sulphide vein stockworks such as the Mayflower and Yellowjacket targets. The Company is actively pursuing both types of mineralization.
