CORVUS GOLD INTERSECTS GOLD-SILVER SYSTEM IN INITIAL EAST BULLFROG SCOUT HOLES AND SOIL SURVEY, NORTH BULLFROG PROJECT, NEVADA
Corvus Gold Inc. has released positive results from the initial two scout drill holes in the new and previously untested Eastern Steam-Heated zone on its North Bullfrog project. Results from the initial holes in the Alunite Hill target area intersected multiple zones of low-grade gold and silver, representing the first confirmation that gold-silver systems are present in this large untested target area (see the table). Mineralization appears to be directly related to the large outcropping alteration system that currently covers 14 square kilometres along the north-northwest-trending structural zone. The first-pass scout drilling in the eastern target area drilled six holes in three of the eight targets to be tested in 2015.
In addition, final results from an initial soil survey of the East Bullfrog structural belt returned a number of surface gold and silver anomalies, which correlate with known, large structural zones and are enhancing targeting for follow-up drilling.
The continuing 2015 drill program is targeting new vein systems as well as the expansion of the YellowJacket deposit in the western resource area. Four to five targets in the WRA will be drilled before returning to the East Bullfrog belt for follow-up and new target testing.
Jeff Pontius, Corvus Gold chief executive officer, stated: "These initial results from our previously untested exploration target area are encouraging. Results have demonstrated the presence of gold-silver mineralization at depth and are directly related to this very large alteration system. In addition, the numerous surface anomalies generated by our most recent soil survey have enhanced our targeting and demonstrated the potential scale of the system. The detection of gold and silver mineralization in the large East Bullfrog target area has the potential to be a game changer for the property, as the area is nearly three times the size of the area hosting our current deposits. Given the strong economic results demonstrated in the company's recent PEA and our ongoing district-wide exploration for new and expanding high-grade discoveries, we believe that Corvus Gold is uniquely positioned in the junior sector to make a major value impact in the coming months."
Alunite Hill target
The initial two scout holes into Alunite Hill intersected a shallow west-dipping structural zone with characteristic high-level alteration and scattered zones of thin stockwork veining. The low-angle, west-dipping nature of the structural zone is analogous to the major controlling structural zone at the historic Bullfrog mine to the south, which also had scattered low-grade gold and silver intercepts distal to the main orebody. The low-grade gold and silver mineralization is also similar to the distal parts of the YellowJacket deposit, in particular with broader areas of silver mineralization generally surrounding gold mineralization. In addition, the occurrence of silver-to-gold ratios of about 10:1 is a good indicator for mineral systems that have potential for high-grade, YellowJacket-type vein systems. The current vectors from these initial two holes and the surface soil results would indicate hotter and better-grade parts of the system would be to the northwest, which is emerging as a strong follow-up target.

* All intercepts utilize a cut-off of 0.1 gram per tonne gold, with the
exception of the stockwork zones, which use a 1.0 g/t gold cut-off.
Reported drill intercepts are not true widths.
At this time, there are insufficient data with respect to the shape of the
mineralization to calculate its true orientation in space.
About the North Bullfrog project, Nevada
Corvus controls 100 per cent of its North Bullfrog project, which covers approximately 72 square kilometres in southern Nevada. The property package is made up of a number of private mineral leases of patented federal mining claims and 865 federal unpatented mining claims. The project has excellent infrastructure, being adjacent to a major highway and power corridor, as well as a large water right.
The North Bullfrog project includes numerous prospective gold targets at various stages of exploration, with four having National Instrument 43-101-compliant mineral resources (Sierra Blanca, Jolly Jane, Mayflower and YellowJacket). The project contains a measured mineral resource of 3.86 million tonnes at an average grade of 2.55 grams per tonne gold and 19.70 grams per tonne silver, containing 316,500 ounces of gold and 2,445,000 ounces of silver; an indicated mineral resource of 1.81 million tonnes at an average grade of 1.53 g/t gold and 10.20 g/t silver, containing 89,100 ounces of gold and 593,600 ounces of silver; and an inferred resource of 1.48 million tonnes at an average grade of 0.83 g/t gold and 4.26 g/t silver, containing 39,500 ounces of gold and 202,700 ounces of silver for oxide mill processing. The mineral resource for the mill process was defined by Whittle optimization using all cost and recovery data and a break-even cut-off grade of 0.52 g/t gold. In addition, the project contains a measured mineral resource of 300,000 tonnes at an average grade of 0.25 g/t gold and 2.76 g/t silver, containing 2,400 ounces of gold and 26,600 ounces of silver; an indicated mineral resource of 22.86 million tonnes at an average grade of 0.30 g/t gold and 0.43 g/t silver, containing 220,500 ounces of gold and 316,100 ounces of silver; and an inferred mineral resource of 176.3 million tonnes at an average grade of 0.19 g/t gold and 0.67 g/t silver, containing 1,077,400 ounces of gold and 3,799,200 ounces of silver for oxide, heap leach processing. The mineral resource for heap leach processing was defined by Whittle optimization using all cost and recovery data and a break-even cut-off grade of 0.15 g/t.

ich kann mir das durchaus vorstellen - habe aber im Moment so meine Zweifel das Tesla es schafft
Bei dem Anstieg sieht es derzeit nach "sell the News" aus. Glaube aber die zieht heute Abend wieder an.
Guten Morgen! 
hab ich total weggeblendet.............aber Danke!
