VANCOUVER, BC, July 23,
2024 /CNW/ - Nevada King Gold Corp. (TSXV:
NKG) (OTCQX: NKGFF) ("Nevada
King" or the "Company") is pleased to announce
assay results from one angle reverse circulation ("RC") hole
recently completed at its Atlanta Gold Mine Project located 264km
northeast of Las Vegas, Nevada, in
the prolific Battle Mountain Trend. Shown in Figures 1 and 2,
today's hole was drilled immediately south of the West Atlanta
Graben Zone ("WAGZ") 200m
south of the Atlanta Pit and represents the southernmost hole
drilled to date into the axial portion of a large, northerly
trending anticline designated the South Quartzite Ridge Target
("SQRT").
Highlights:
- Today's intercept of 6.28 g/t Au over 54.9m occurs in strongly altered intrusive
rock starting 147.9m downhole,
immediately below a non-mineralized, massive quartzite unit that
caps the top of the South Quartzite Ridge Anticline (Figures 1 and
4). The hole was steeply angled at -85o southward along
the anticlinal axis of the SQRT to test a large, low resistivity
CSAMT anomaly occurring underneath the highly resistive quartzite
cap (Figure 3). This axial zone aligns with major, high-angle
faults controlling felsic intrusions and associated gold
mineralization further north within the resource zone and is most
likely a southern extension of the WAGZ.

Table 1. Hole reported today.
Mineralization occurs within an irregularly shaped intrusive body
with true mineralized thicknesses estimated to be 85% to 95% of the
reported drill intercept length.
- This hole is significant for several reasons:
- The high-grade gold mineralization in this hole has
remarkably consistent grade over the 55m interval (see Figure 6)
with the mineralization interpreted to have been focused in the
intrusive host by the pooling of mineralizing fluids under the
impermeable quartzite unit. Previous work provided indication for
the potential for blind mineralization under the quartzite unit,
particularly because gold mineralization was identified
approximately 2.5km apart underneath its lateral boundaries. With
these new results, testing for blind, high-grade mineralization
underneath the SQRT will be a focus of future drilling.
- The extension of high-grade oxide mineralization southward
beneath the Eureka Quartzite strongly enhances potential for
extending the Atlanta resource
zone into the areally extensive SQRT, which possesses a 2.5km
strike length and ranges up to 1km wide. The SQRT is contiguous
to the Atlanta resource zone and
on trend with the major faults that are interpreted as the
primary plumbing for the mineralizing fluids that deposited
high-grade gold at Atlanta. These
major feeder structures include the West
Atlanta, West Atlanta #1
and #2, and East Atlanta Faults.
- The northerly trending SQRT coincides with the broad South
Quartzite Ridge Anticline (Figure 4), which formed a structural
trap or cap above the underlying intrusive rock, thus concentrating
gold-bearing fluids and subsequent mineralization along the
anticline's axial portion. This is clearly evident from the hole
assays shown in Figure 6, where gold values in the quartzite are
almost non-existent compared to the strong Au mineralization
immediately below it in the intrusive rocks. Axial portions of
anticlines constitute important traps for gold mineralization
within Nevada and elsewhere throughout the world, and the quartzite
forming the South Quartzite Ridge Anticline could potentially be
concealing a significant mineralized body that has never been
drill-tested nor been revealed with surface sampling due to its
highly impermeable nature.
- The oxide gold in AT24HG-41 is hosted within an intrusive suite
consisting of variably silicified and argillized rhyolitic
dikes and adjacent rhyolite-dominated explosive tuff dike breccia
bodies. The sustained, consistent high gold grades seen in these
intrusive units are very unusual at Atlanta, and when compared to the
intrusive-hosted mineralization seen in holes further north along
the WAGZ, the much higher grades encountered in AT24HG-41
demonstrate an abrupt southward strengthening of gold
mineralization. Today's hole demonstrates that felsic intrusive
rocks at Atlanta are capable of
hosting a type of high-grade mineralization that can potentially
produce a significant gold system more akin to Kinross Gold's large gold mine at Round Mountain, Nevada (located 240km west of
Atlanta and with 16 million ounces
of gold produced through 2022 - Source: USBM Nevada Mineral
Explorer Website, 2023). This potential certainly applies to
the SQRT, and beyond that, the many low resistivity zones (a few of
which are shown in Figure 4) revealed by the CSAMT data also
constitute valid exploration targets hosting similar high-grade
potential across the Atlanta
District.
- AT24HG-41 intersected mineralization approximately
20m from previously released
AT23HG-34, which also encountered a large cap of Eureka Quartzite
before contacting strongly mineralized intrusive, including 4.50
g/t Au over 27.4m within 2.15 g/t Au
over 96m. AT24HG-41 is set apart from
its neighboring holes as it is the closest to test the continuation
of mineralization southward beneath the South Quartzite Ridge
Anticline, as well as intersecting the most consistent,
high-grade intrusive-hosted mineralization at Atlanta to date.
- The SQRT remains a high potential, undrilled target area with
the exception of eight historic drill holes (Figure 1) put down by
Bobcat Exploration in the late 1970s. The Bobcat holes averaged
73m in depth and so did not test the
core location of this newly developing zone under the quartzite
where Au mineralization starts at around 150m depth. Six of the Bobcat holes drilled along
the western margin of the SQRT and distant from the anticlinal axis
contained no significant gold values. The other two Bobcat holes
were drilled at the southern end of the SQRT and closer to the
anticlinal axis, with both holes reporting gold values in the 0.30
g/t Au range. This anticlinal axis appears to be the main control
over gold mineralization along the SQRT, and as seen in Figure 4,
the Company's reconnaissance program is designed to hit the axial
portion with a combination of vertical and shallow angle
holes.
Cal Herron, Exploration Manager
of Nevada King, stated, "I cannot
over-emphasize the significance of AT24HG-41 – in my opinion, it is
the most important hole Nevada King
has drilled to date at Atlanta.
Higher-grade intervals have been hit including previously released
AT23WS-44 (11.64 g/t Au over 108.2m),
but this and other holes conform to our previous interpretation of
high-grade gold mineralization focusing in intensely silicified
intersections of faults. In contrast, the 54.9m @ 6.28 g/t Au in AT24HG-41 occurs within
variably silicified-argillized aphyric rhyolite and fine-grained
porphyritic rhyolite tuff dike breccias possessing very sparse
quartz veinlets. These rocks are pervasively altered and the gold
appears to be disseminated within the groundmass and/or
concentrated in loose oxides or fractures. There is no evidence of
significant quartz veining or strong faulting seen in the cuttings.
We believe that gold mineralization was coeval (having the same
age) with the felsic intrusions and became trapped beneath the
massive quartzite cap along the South Quartzite Ridge anticlinal
axis. These felsic gold hosts are easily tracked southward from
AT24HG-41 by the consecutive sequence of low resistivity anomalies
shown along CSAMT lines 2, 5, and 10 (Figure 5) underneath the
strongly resistive quartzite cap. Gold enrichment is most likely to
occur within the axial plane region of the anticline, which would
move our actual drill targets in closer to the centre of the
anticline, meaning we need to drill along the crest of the
Quartzite Ridge or from positions near the crest.
"Gold enrichment in AT24HG-41 rapidly drops below 213m depth at the contact with underlying fine
grained porphyritic rhyodacite and dacite that compose a large
altered dike (or small, elongate stock) bounding the SQRT's western
margin. These dacitic intrusions are exposed at the surface all
along the western side of the SQRT, while the rhyolitic rocks
associated with gold mineralization crop out along the axis of the
South Quartzite Ridge Anticline. Surface rock sampling shows the
dacitic rocks to be largely barren of Au, whereas the aphyric
rhyolite dikes extending north and south from historical tunnels
just west of the anticlinal axis are associated with
mineralization. Between the CSAMT data, outcrop exposures, and
surface samples we have good reason to drill-test the full length
of the SQRT.
"The long, high-grade intercept in this hole is highlighting not
only the SQRT, but also a number of other low resistance zones
identified elsewhere on the larger Atlanta property, which covers an extensive
collapsed caldera system. AT24HG-41 has increased our confidence in
the potential for intrusive-hosted mineralization within the
Atlanta District, particularly in
areas that may be similarly capped by an impermeable, unmineralized
unit. These new target areas significantly exceed the footprint of
the Atlanta resource zone (see
Figure 4), and with this new drill confirmation, the CSAMT survey
data opens up large areas to drill test for similar high-grade
mineralization."

Discussion of South Quartzite Ridge Target:
The overall north-south trend to mineralization at Atlanta was recognized long before the deposit
was open-pitted, but exploration outside of the pit area largely
concentrated on chasing a potential northern extension. Potential
for a southern extension into the SQRT was considered to be very
low, largely because the massive, barren quartzite bounding the
southwestern side of the historical pit presented serious
challenges, namely lack of obvious mineralization and poor access.
Two historical angle holes about 350m
deep drilled under the western flank of the ridge hit Eureka
Quartzite and underlying Pogonip Limestone but did not encounter
Au-Ag mineralization, so efforts to test the ridge ceased by 1998.
The general consensus at that time was that mineralization at the
southern end of the pit was cut off by the South Fault and little
if any potential existed for significant extension southward.
However, Nevada King's 2021 drilling
directly south of the pit showed that mineralization did indeed
extend south of the South Fault, while the seven E-W oriented CSAMT
lines crossing the Quartzite Ridge in 2022 indicated a prominent
and persistent, sub-horizontal resistivity low underlying the
ridge's massive, highly resistive quartzite cap starting about
200m below the ridge crest (Figure
5).
Hole AT23HG-37 along Section 22-4N was sited on the northern end
of the SQRT in order to test for mineralization underneath the
quartzite. The hole collared in massive quartzite and drilled out
of largely barren quartzite and into mineralized felsic intrusive
tuff and rhyolite at 175m depth, with
mineralization continuing to 285m.
The contact between intrusive tuff and unaltered Pogonip Limestone
was hit at 430m depth. This
stratigraphic sequence is seen reflected in the resistivity section
shown in Figure 5 along CSAMT Line 10. Projecting the hit in
AT23HG-37 southward onto Line 10, the hole would penetrate the gold
zone 40m west of the West Atlanta
Fault. This same stratigraphic profile is repeated southward past
CSAMT Line 7 more than 400m south of
AT23HG-37, which now opens up a large area along the anticlinal
axis in which to pursue the type of thick mineralization penetrated
in holes AT23HG-37 and AT23HG-34, and now in hole AT24HG-41, within
a part of the property that has never been previously
drill-tested.
QAQC Protocols
All RC samples from the Atlanta Project are split at the drill
site and placed in cloth and plastic bags utilizing a nominal 2kg
sample weight. CRF standards, blanks, and duplicates are inserted
into the sample stream on-site on a one-in-twenty sample basis,
meaning all three inserts are included in each 20-sample group.
Samples are shipped by a local contractor in large sample shipping
crates directly to American Assay Lab in Reno, Nevada, with full custody being
maintained at all times. At American Assay Lab, samples were
weighed then crushed to 75% passing 2mm and pulverized to 85%
passing 75 microns in order to produce a 300g pulverized split.
Prepared samples are initially run using a four acid + boric acid
digestion process and conventional multi-element ICP-OES analysis.
Gold assays are initially run using 30-gram samples by lead fire
assay with an OES finish to a 0.003 ppm detection limit, with
samples greater than 10 ppm finished gravimetrically. Silver
samples that run greater than 100ppm are also finished
gravimetrically. Every sample is also run through a cyanide leach
for gold with an ICP-OES finish. The QA/QC procedure involves
regular submission of Certified Analytical Standards and
property-specific duplicates.
The PQ-diameter core was sampled in the Company's warehouse in
Winnemucca, Nevada, with whole
core samples being placed in heavy canvas bags and sent to American
Assay Lab in Reno, Nevada, in
heavy shipping bags by a Company contractor with full custody being
maintained at all times. CRF standards and coarse blanks were
inserted into the sample stream on a one-in-twenty sample basis,
meaning both inserts are included in each 20-sample group. At
American Assay Lab, samples were weighted then completely crushed
to -1 inch. The coarse-crushed sample was quarter-split and one
quarter was reduced to 75% passing 2mm. A 300g split was
subsequently pulverized to 85% passing 75 microns. Prepared samples
are initially run using a four acid + boric acid digestion process
and conventional multi-element ICP-OES analysis. Gold assays are
initially run using 30-gram samples by lead fire assay with an OES
finish to a 0.003 ppm detection limit, with samples greater than 10
ppm finished gravimetrically. Every sample is also run through a
cyanide leach for gold with an ICP-OES finish. The QA/QC procedure
involves regular submission of Certified Analytical Standards and
property-specific duplicates.
