Corvus Gold Inc. (TSX:KOR) reported that Phase II of its 2015 drilling program at the North Bullfrog Project, Nevada commenced on August 11th. The reverse circulation drill program will focus on testing new high-grade discovery targets in the large unexplored Eastern Steam-heated Zone, and defining new high-grade systems similar to the recent Yellow Jacket discovery. The 8,000 metre program will follow-up on new geologic, structural and mineralization results from the phase I drilling program completed in the spring of 2015.
As quoted in the press release:
The phase II drill program will test a number of priority new discovery and resource expansion targets in and around the existing North Bullfrog deposits (Figure 2). Two of these targets were tested in the early 2015 phase I, “proof of concept” drilling program, the results of which have confirmed the key structural and mineralization controls. At the North Sierra Blanca target a northeast trending high level stockwork vein system returned +1 g/t gold intercepts from high level stockwork veining over several meters. This new vein system appears to mirror the YellowJacket zone some 400 metres to the west (NR15-08: July 9, 2015). At the Liberty target which is 500 metres south of the YellowJacket deposit, drilling has intersected a high level quartz stockwork vein system with high mercury values and low grade gold and silver which is characteristic of the tops of the YellowJacket system. Follow up drilling will be conducted at both targets to evaluate these new stockwork systems at depth in the projected productive zones.
In addition, a number of other structural/high-grade targets will be tested in the greater Sierra Blanca and Jolly Jane areas including the Air Track/366 target (following up hole NB-13-366 with 20m of 1.03 g/t Au & 17.5m @ 1.26 g/t Au under shallow pediment cover, NR14-01, January 9, 2014) and North YellowJacket (Rhyolite Vein 11.3m @ 3.3 g/t Au, NR14-17: September 4, 2014). The setting of the Jolly Jane is similar to the Sierra Blanca/YellowJacket deposits with two major bounding structural zones on the east and west sides of a large low-grade deposit. It is believed that these structural zones could host similar high-grade mineralization to that at YellowJacket and will be initially tested in the phase II program.
Corvus Gold President and CEO, Jeff Pontius, said:
“The positive results from Corvus Gold’s preliminary economic assessment which incorporates the new high-grade YellowJacket discovery have demonstrated the high potential of the North Bullfrog District. New surface and drill hole exploration data linked to the gold depositional controls defined at YellowJacket has now outlined a number of prospective new discovery and potential resource expansion targets across the District. The two pronged phase II drill program will focus on the evaluation of near-term high-grade resource expansion in the west and new large deposit discovery potential in the east. We believe that the large new Eastern Steam-heated target area which covers some fourteen square kilometres has the potential to host additional YellowJacket or Bullfrog-type deposits. This next round of exploration at North Bullfrog holds the potential to expand an existing, highly prospective, high margin deposit.”
