VANCOUVER, BC, May 11, 2021 /CNW/ - Northern Vertex
Mining Corp. (TSXV: NEE) (OTC NASDAQ INTL.: NHVCF) (the
"Company" or "Northern Vertex") a U.S.-focused gold
producer with district-scale exploration projects in the Walker
Lane Trend, is pleased to report the initiation of a seven-hole
drill program to follow up on and expand known mineralization on
the regional West Oatman Trend. The West Oatman vein system
runs parallel to the Moss vein and has similar
characteristics. Previous drilling has defined mineralization
along approximately one kilometer of strike. Mineralization remains
open along strike and at depth.
The drill program is designed to follow up on recent and
historic drilling which returned multiple significant intercepts
including hole AR20-259R (see news release dated August 12, 2020) which returned:
53.34 meters grading 0.81 g/t gold
and 14.77 g/t silver (1.01 g/t AuEq), including 18.29 meters
grading 1.55 g/t gold and 35.19 g/t silver (2.02 g/t AuEq), where
AuEq = Au + Ag/75
The West Oatman drill program is expected to run in parallel
with ongoing brownfields exploration in and around the Moss Mine,
including the high-grade Ruth
Vein.
Key Points:
- The West Oatman target is located only 2.3 kilometers from the
Moss Mine.
- West Oatman vein system appears to be analogous to the Moss
Mine veins system.
- Moss and West Oatman are part of the historic Oatman mining
district which is known to have produced more than two million
ounces of gold.
- Initial follow up will be comprised of 800 meters of diamond
core drilling in seven holes to test the system along strike and at
depth.
- Previous drilling indicates that the West Oatman vein system
contains gold and silver mineralization along a strike length of at
least 1,000 meters, and that mineralization appears to increase in
both grade and thickness with depth.
Northern Vertex President, Michael G.
Allen commented, "Central to our objective of creating
value for Northern Vertex shareholders is articulating the regional
upside of the Moss Property, which is in an area that has
historically produced more than two million ounces of gold. After
consolidating multiple historical databases, we are pleased to
present recent and previously unreleased drill results from one of
our most high priority targets, West Oatman. By following up with
core drilling, our goal is to rapidly determine the geometry and
controls of the gold and silver mineralization at a target where we
see significant potential for expansion."
West Oatman Target
The West Oatman Target is a bulk tonnage exploration target
located on the south side of Silver
Creek, approximately 2.3 kilometers to the south of the Moss
Mine (Figure 1 West Oatman Target Location). Exploration is
currently focused on the fault-hosted West Oatman vein system,
which is exposed on surface as a large area of well-developed
epithermal quartz-calcite veins, breccia, and stockwork. The host
fault has been mapped for over 4.5 kilometers and is interpreted to
be an extension of the Gold Road structure to the southeast.
The West Oatman vein system is similar to the Moss vein system that
is currently being mined.
Mapping, surface sampling, and previous drilling on the West
Oatman Target have indicated that the West Oatman vein system is
potentially mineralized over a strike length of at least one
kilometer, with the host structure striking 290 degrees and dipping
approximately 65 degrees to the northeast. Vein, stockwork, and
breccia widths vary from less than a meter to approximately 30 to
50 meters in width in breccia-filled dilation zones. Limited
drilling of the West Oatman vein system at depth indicates that
mineralized intersections appear to increase in both grade and
thickness with depth.
Northern Vertex in 2014 collected 267 surface rock chip and
channel samples from along a one-kilometer strike length of the
West Oatman vein system (Figure 1 West Oatman Target Location). The
sampling yielded average values of 0.50 g/t Au and 3.72 g/t Ag,
with individual samples ranging from below detection to 8.19 g/t Au
and 51.50 g/t Ag.
The West Oatman vein system is open along strike to the east and
west, and at depth.
West Oatman Drilling Program
Northern Vertex drilled 894.2 m in
13 HQ diameter diamond core drillholes (2017) and 121.1 m in a single Reverse Circulation (RC)
drillhole (2020) at the West Oatman Target (Figure 2 Drillhole
Location Map, West Oatman Target). Drill results for Northern
Vertex's 2017 drilling on the West Oatman Target were not
previously released. Results from drillhole AR20-259R (see News
Release dated August 12, 2020), which
tested the structure at depth, support the apparent increase in
mineralization intersection grade and thickness with depth
indicated by the historic Reynolds Metals drilling (see
below;Figure 3 Cross Section through West Oatman vein system).
Results from this drilling are presented in Table 1 and Table
2.

Boart Longyear. RC samples, collected every 1.52 m, were
transported in sealed bags to Skyline Assayers and Laboratories
(Skyline) in Tucson, AZ. Field control QAQC samples, including
standards, blanks, and field duplicates, were inserted into the
sample stream at a rate of one field control sample every six
regular samples. Gold was determined by fire-assay fusion of a 30 g
sub-samples with atomic absorption spectroscopy (method FA-01).
Overlimit samples of gold were assayed by gravimetric means
(FA-02). Skyline Laboratories is accredited in accordance with
ISO/IEC 17025:2017 and ISO 9001:2015.

Note: True thickness ranges between
approximately 82% and 94% of the reported interval thickness for
drillholes inclined between -60 degrees and -45 degrees,
respectively. Assay data are uncapped. AuEq = Au + Ag/75. Diamond
core drilling was conducted by BDW Drilling of Guadalajara, Mexico.
Field control QAQC samples included standards, blanks, and field
duplicates that were inserted into the sample stream at a rate of
one field control sample per twelve regular samples. Half core
samples were submitted to Bureau Veritas Mineral Laboratories (BVM)
in Sparks, NV. Gold was determined by fire-assay fusion of a 30 g
sub-samples with atomic absorption spectroscopy (method FA430).
Overlimit samples of gold were assayed by gravimetric means
(FA530). Multi-element data for 35 elements were collected by
Inductively Coupled Plasma Emission Spectroscopy (MA300). BVM has a
comprehensive quality management system meeting the requirements of
ISO/IEC 17025 and ISO 9001.
|
Diamond core and RC cutting logging and sampling were conducted
by professional geologists. Results from Northern Vertex's drilling
appears to have validated the results of earlier drilling programs,
confirming the tenor of gold and silver mineralization over a
strike length of approximately 550 meters of the West Oatman vein
system.
Upgrading our Databases - Historic Drilling
The Company has been able to locate two historic data sets for
drilling on the West Oatman Target, Reynolds Metals (1992) and
Grubstake Mining Company (1961; Grubstake). The Reynolds Metals
drilling shows that mineralization tends to thicken with depth. The
Grubstake drilling appears to show the presence of shallow
high-grade mineralization.
Historic holes tested approximately one kilometer of strike of
the West Oatman vein system.
A. Reynolds
Metals Drilling (1992)
Reynolds Metals conducted 1,411.22 meters of RC drilling on part
of the West Oatman vein system in 1992 (Figure 2 Drillhole Location
Map, West Oatman Target). Highlights include hole BW92-01, which
returned 24.4 meters grading 0.72 g/t Au, and BW92-06, which
returned 42.7 meters grading 0.89 g/t Au (Table 3). Silver was not
assayed for.
The drilling tested the system along a strike length of almost
one kilometer and mineralized intersections appear to be increasing
in thickness with depth (Figure 3 Cross Section through West Oatman
vein system).

Reynolds Metals samples were assayed by Chemex Labs Inc. (now

against original documentation and laboratory assay certificates.
No bias was noted in the gold distribution sampled by the Reynolds
Metals drilling compared to that sampled by spatially proximal
Northern Vertex drilling.
B. Grubstake
Mining Company Drilling (1961)
Grubstake conducted a diamond drilling program along
approximately 610 meters of the West Oatman vein system. A total of
277.06 meters was drilled in six diamond core drillholes and
results are summarized in Table 4.

Note: Grubstake Mining Company drillholes
are not to be relied on and AuEq has not been determined for this
dataset due to incomplete sampling and inability to independently
verify assay data against original assay certificates. True
thickness is estimated to be approximately 42% of the reported
interval thickness for vertical drillholes and 54% for the -82
degrees inclined drillhole. Assay data are
uncapped.
