Corvus Gold Ongoing Drill Program Continues to Expand Sierra Blanca Deposits to the West at North Bullfrog Project, Nevada

256 Days ago

VANCOUVER, British Columbia, Sept. 23, 2019 (GLOBE NEWSWIRE) -- Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX: CORVF) announces it has received assay results from additional stepout drill holes testing the western extension of the Sierra Blanca Deposit on the 100% owned North Bullfrog project, Nevada (Table 1). Results continue to expand mineralization that has shown potential for the North Bullfrog deposits to be developed as a multi-phase, low strip, open-pit heap leach project (Figure 1). The current drill program is evaluating the extension of the regional scale gold system, which in the current gold price environment is an attractive target given the large size potential.

Corvus continues to work on a project plan that it believes would have lower capex and a rapid start-up development phase, with a smaller footprint, for a near-term open-pit mining project. The Phase-1 focus of the plan is centered on the high-grade oxide vein system at YellowJacket and surrounding north Sierra Blanca area of the North Bullfrog project, where baseline environmental permitting is well advanced and key infrastructure is in hand (power & water).

The most recent results west of Sierra Blanca continue to demonstrate the system extends west under shallow pediment cover which is being systematically explored for both bulk tonnage disseminated zones as well as intervening vein systems similar to YellowJacket on the east side of the deposit. Newly identified mineralization to the west is generally shallow and in the case of holes NB19-469 (39.6m @ 0.71 g/t Au) and NB19-470 (6.1m @ 1.05 g/t Au) are associated with fine stockwork quartz veins which are typically distal to a YellowJacket type system. These two holes are the farthest west holes drilled to date and may indicate the potential for another structurally controlled vein system under the pediment to the west. 

Jeffrey Pontius, President and CEO of Corvus, said, “The ongoing results from our West Sierra Blanca (WSB) target are encouraging in that we could expand our North Bullfrog Phase-I resource base. Phase-I of the overall North Bullfrog mining plan is emerging as a key component to the new optimized Corvus Gold District development plan that provides a low-risk financial driver for an expanding production plan. In addition, Corvus continues to aggressively drill its priority 'new discovery' targets with follow-up holes at Cat Hill, North Jolly Jane and South YellowJacket which are looking promising for our ability to expand existing deposits and define new discoveries, highlighting the exploration potential of the greater Bullfrog District. With the recent rise in gold price Corvus sees great potential with expanding the large low-grade mineral system that extends throughout the North Bullfrog and new Gap target areas. This work, linked with encouraging resource expansion results at both North Bullfrog and Mother Lode, paint an attractive picture for a possible fast track project, which Corvus believes could deliver a true Nevada scale operation.”
