RC And Core Holes Completed At the Atlanta Gold Mine Project
VANCOUVER - Nevada King Gold Corp. reported on nine reverse circulation (RC) holes and two core holes completed at its Atlanta Gold Mine Project located 264km northeast of Las Vegas, Nevada in the Battle Mountain Trend. These holes were drilled across the high-grade feeder zone associated with several strands of a braided network of structures comprising the Atlanta Mine Fault Zone
The holes tie into 2021 hole AT21-62, which returned 55m averaging 5.34 g/t Au starting at 9.1m depth on the east end of Section22-8N. These holes continue to encounter high-grade gold and silver mineralization, hosted in oxide material, tracking it to the west across the AMFZ where it remains open both to the west and to depth. Core holes AT22HG-1T and AT22HG-2T bottomed in Au-Ag mineralization at depths of 293m and 265m, respectively. Holes AT22NS-20 (33.5m of 3.43 g/t Au and 125.7 g/t Ag) and AT22NS-53 (67.1m of 2.88 g/t Au and 52 g/t Ag) penetrated the silica breccia zone directly above a fine-grained dacite porphyry dike that was also encountered south of this section along the western boundary of the West Atlanta Fault on Section22-6N. Hole intercepts above and adjacent to this intrusive unit tend to host higher Au-Ag grades, and the volcanic section west of the intrusion is mineralized, unlike areas east of the intrusion.
Mineralization in hole AT22NS-71 (51.8m @ 2.95 g/t Au and 79.5 g/t Ag) is hosted within silicified breccia that is sandwiched on top and bottom between mineralized porphyritic quartz latite tuff dike breccia bodies. Beneath the mineralized zone, AT22NS-71 cut down through barren dolomite, then through anomalous tuff dike breccia, and finally through the Atlanta King Fault (AKF) and into quartzite. This lithotype sequence strongly suggests the AKF is serving as a conduit for channeling felsic dikes and dike breccia bodies into the silica breccia horizon. Higher Au-Ag grades are frequently found in the silica breccia proximal to these tuff dikes further south along the AKF. The Company is utilizing this close spatial relationship between these dikes and Au-Ag mineralization as an important exploration guide for finding higher grades as it advances the drills northward along the AMFZ.
Cal Herron, Exploration Manager, said, "Section 22-8N is important for revealing two distinct zones of higher grade Au-Ag mineralization along the AMFZ – one coinciding with narrow fault blocks developed along the West Atlanta Fault, and the other occurring within narrow fault-bounded blocks formed in between the Atlanta King and East Atlanta Faults. This is most evident in the 13m-wide fault block drilled by historical holes 88-9, 88-14, AC-1 and KR97-6. The clustering of high-grade hits reported in these four holes is highly unusual at Atlanta, but this is in part due to the unusually high hole density along this section. With this fault block so well defined, Nevada King is now in good position to track the high-grade structure along strike to the north and south. Similarly, the 30m wide fault block zone between the Atlanta King and East Atlanta Faults is becoming better defined and we are now able to track it along strike as well. This level of definition was not provided by historical drilling, and these new results will aid in accurate modeling of these high-grade zones.
It is also important to note the close spatial relationship between the Atlanta King Fault, intrusive tuff dikes, and higher grade Au-Ag mineralization. We have already seen this relationship in other holes south of Section 22-8N, and has become an important indicator for tracking gold mineralization southward from the pit into the South Extension Target and beyond. The Atlanta King Fault is exposed along strike for about one kilometer south of the pit, however the down dropped block east of the fault that would potentially host mineralization is largely covered by quartzite scree and landslide debris, so the primary target of interest is not exposed. This area has never been drilled and exploration of this target will commence in May of this year after ground conditions improve."
