Corvus Gold Intercepts Additional Gold Mineralization from Surface at North Bullfrog, Nevada
Highlights include:
|
NB-12-195: 47 metres of 0.6 g/t gold from surface
NB-12-196: 65 metres of 0.3 g/t gold from surface NB-12-197: 96 metres of 0.3 g/t gold from 16 metres |
Vancouver, B.C., Corvus Gold Inc. (“Corvus” or the “Company”) – (TSX: KOR, OTCQX: CORVF) announces the latest assay results from the first 10 drill holes of a 33 hole program on private (patented mining claims) land within the Jolly Jane deposit known as the ZuZu Zone. Initial results have shown the outcropping at the ZuZu zone to be thicker and overall higher grade than the previously defined estimated resource in this part of the deposit, as illustrated by hole NB-12-195 returning 47 metres of 0.60 g/t gold starting at surface. Drilling at Jolly Jane was designed to upgrade and expand the existing inferred gold resource to measured and indicated for inclusion in the Mayflower project feasibility study, presently underway and scheduled for release in Q1 of 2013.
This additional zone of mineralization on private land could significantly enhance the economics of the Mayflower project by adding additional early stage gold ounces where production is anticipated for late 2014.

Jeff Pontius, Corvus Gold CEO, stated: “The ZuZu Zone offers a great opportunity to add to our proposed early production at the Mayflower project with its very low strip ratio and deep oxidation. We look forward to the rapid completion of this strategic drilling program as well as the return of the remainder of the Yellow Jacket high-grade zone drill results which should be available in the next few weeks. As our work progresses at North Bullfrog, we continue to be encouraged as this exciting mining opportunity moves closer toward becoming Nevada’s next operating gold mine”.
ZuZu Zone Drilling
The Company’s recent updated Preliminary Economic Assessment for the North Bullfrog project (see NR12-37, December 6, 2012) highlighted the opportunity for additional leach pad capacity for the Mayflower project. The ZuZu zone at the Jolly Jane deposit (Figure 1) has emerged as a possible source for low strip ratio oxide mineralization also situated on private land to take advantage of this added capacity. A drill program was initiated in November 2012 and initial results have shown that good continuity exists in the zone and it is thicker than originally projected. Following return of all assay results a new estimated resource will be calculated and utilized in the ongoing Mayflower feasibility study which will form the basis for the mining permit submission scheduled for Q2 2013. The ZuZu program will consist of 33 holes totalling 4000 metres, and is scheduled for completion in January, 2013.
The first drilling has defined the northern limits of the mineralization bounded by a fault down dropping the preferred host unit below volcanic cover and has also confirmed the structural and host rock continuity of the mineralized zone to the south. It appears that mineralization is closely related to a set of NE-trending structures that may have acted fluid pathways.

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.
