Westward Gold Provides Update on
Results of Nevada Hyperspectral Surveys
Vancouver, British Columbia, November 9, 2021 -- InvestorsHub
NewsWire -- Westward Gold Inc. (CSE: WG, FSE: IM50) ("Westward" or the
"Company") is pleased
to announce the results of its previously-disclosed hyperspectral
core imaging and airborne hyperspectral campaigns at its Toiyabe
and Turquoise Canyon Projects located on the Battle Mountain -
Eureka Trend in Lander County, Nevada ("Toiyabe" and "Turquoise Canyon", respectively)
(see press releases dated
August 10, 2021 and October 5, 2021 for
reference).
The initial results of the two surveys confirm a large
hydrothermal footprint at Toiyabe, resulting in alteration of
favourable host rocks, predominantly the Wenban and Roberts
Mountains Formations. These formations are also important hosts at
many nearby large-scale gold mines and deposits, including
Pipeline, South Pipeline, Crossroads, Cortez Pits, and Cortez
Hills. The recent hyperspectral data builds upon the legacy data
and improves understanding of the relationship between gold
mineralization controls, and alteration. The newly-identified and
quantified alteration will aid as a pathfinder to mineralization,
allowing Westward to optimize future drill targets and potentially
expand upon previous significant intercepts. The Company is in the
process of planning its inaugural drill campaign for the first half
of 2022.
Hyperspectral Core
Imaging
TerraCore Geospectral Imaging in Reno, Nevada
("TerraCore")
performed hyperspectral core imaging on approximately 3,050 meters
of diamond drill core and 9,140 meters of reverse circulation chips
inherited from past operators. Hyperspectral imaging is captured
through measuring the reflectance and absorption of infrared energy
on the surface of the core. This non-destructive measurement
quickly provides information about mineralogy, mineral chemistry,
and mineral texture. TerraCore's full-range hyperspectral system
was utilized, producing high-resolution true colour photographs at
0.1mm resolution, and infrared images across the Near-, Short-, and
Longwave-Infrared regions at 1mm pixel resolution. The wavelengths
used are necessary for Carlin-type gold deposits given their
ability to detect a wide range of minerals including clay,
carbonate, silica, and associated alterations. All hyperspectral
imagery is converted into an objective, numerical dataset that can
readily be imported into the Toiyabe database and 3D
model.
Key Highlights (1)
-
Hydrothermal alteration
associated with various styles of gold mineralization was assigned
to four distinct categories: (A) Fault-controlled mineralization,
(B) Carbonate lithology proximal to structure, (C) Carbonate
lithology distal to structure, and (D) Quartz veining with argillic
alteration
-
Alteration Type A
- Fault-Controlled Mineralization (see Figure 1 below) demonstrates a decreased
carbonate presence, suggesting strong decalcification and
silicification. Argillic alteration increases with proximity to the
high-grade Courtney Zone in the southeast, as demonstrated in hole
T-706 which had reported gold intervals of 5.5 g Au/t over 10.7
meters from 51.8 - 62.5m, including 11.1 g Au/t over 4.5 meters
from 54.9 - 59.4m and a separate interval of 18.0 g Au/t over 4.6
meters from 71.6 - 76.2m, including 26.4 g Au/t over 3.1 meters
from 71.6 - 74.7m
-
Alteration Type B
- Carbonate Lithology Proximal to Structure (see Figure 2 below) demonstrates
silicification with argillic alteration halos extending up to 60m
away from high-grade intercepts (+2 g Au/t gold). Hole T-1601
reported 3.55 g Au/t over 7.6 meters from 253.9 - 261.5m, including
13.2 g Au/t over 1.5 meters from 258.5 - 260m, and intervals of
1.22 g Au/t over 2.5 meters from 269.1 - 271.6m, 1.34 g Au/t over
7.5 meters from 286.8 - 294.3m. All intercepts are within the
alteration halo observed in the core imaging dataset
-
Alteration Type C
- Carbonate Lithology Distal to Structure (see Figure 3 below) is similar to Type B but
with lower-grade gold anomalies, likely caused by its distance to
the mineralizing structure, yet still exhibits large alteration
halos as seen with Type B
-
Alteration Type D
- Quartz Veining with Argillic Alteration (see Figure 4 below), though less common,
exhibits decalcification and argillic alteration centered on
silicified veins containing anomalous gold values. An example from
hole 901C included 1.44 g Au/t over 6.1 meters from 56.4 to
62.5m
-
Argillic alteration varies from
zones of illite associated with structures and intrusive
dikes/sills, to kaolinite associated with unique lower-plate
carbonate rocks. Kaolinite appears to develop in specific units of
the Wenban Formation, an important lower-plate gold host in the
Battle Mountain - Eureka Trend
-
In all mineralization types, the
alteration appears to be centered around structures which act as
fluid conduits and are generally associated with anomalous gold
values. The broad zones of alteration observed in Types B and C,
and the changes in mineralogy observed in Types A and D, provide
key vectors to mineralization, and will guide future drill
programs. The alteration present at the Toiyabe project is
comparable to that observed in the nearby Pipeline and Cortez Hills
deposits (source: NI 43-101

Dave Browning, Vice President of Exploration, noted "the
large alteration halos will be crucial for exploration planning as
they indicate areas of mineralization that may have been missed by
previous drill campaigns. Understanding the association between
anomalous gold values and alteration types will optimize our future
targets and will inform our technical team during the drill
campaign with regards to proximity of mineralization."

Hyperspectral Airborne
Survey
In conjunction with the core imaging, the Company also
completed an airborne hyperspectral survey, carried out by SpecTIR,
LLC and processed by Ethos Geological Inc. A total area of ~35
square kilometers has been processed, including both Toiyabe and
Turquoise Canyon, and surrounding land. Near-, Short-, and
Longwave-Infrared cameras were also used for the airborne survey to
allow for direct comparison to the core imaging dataset. The
airborne survey has identified alteration minerals along the
surface expression of structures, indicating these structures
likely acted as fluid conduits similar in nature to those observed
in the Toiyabe drill core.
Key Highlights
-
Argillic alteration as described
in the core imaging at Toiyabe is observed at Turquoise Canyon in
the form of muscovite and illite signatures
-
The distribution of alteration
minerals seen on the surface at Turquoise Canyon confirms
previously-inferred structures, and is spatially associated with
anomalous gold, silver, arsenic, lead, and zinc in soil
-
Ammonium illite, an indicator
mineral for fluid flow not detectable by the human eye, has been
identified along near-surface structures in the core and at
surface. Spatial extent of the ammonium minerals has identified
hydrothermal fluid pathways leading to additional drill targets at
the Toiyabe and Turquoise Canyon Projects
Mr. Browning also commented: "Having access to the drill
samples from Toiyabe's Courtney Zone (which hosts a historical 170
koz gold resource estimate (2)) is vital
to understanding the alteration associated with mineralization in
the district. Being able to identify that same alteration pattern
via airborne hyperspectral data will lead to the identification of
high-priority areas for follow-up sampling, mapping, and drilling
at Turquoise Canyon. This correlation will reduce exploration risk
and optimize future exploration spending across the
district."

Report, American Consolidated Minerals Corporation, Prepared by
Paul D. Noland, P. Geo., May 27, 2009 (the "2009 Technical
Report"). A qualified person
has not done sufficient work to classify the historical estimate at
Toiyabe (the "Historical
Estimate") as current
mineral resources and Westward is not treating the Historical
Estimate on Toiyabe as a current mineral resource, as defined in
National Instrument 43-101 - Standards of Disclosure for Mineral
Projects ("NI
43-101"). The Historical
Estimate was calculated using mining industry standard practices
for estimating Mineral Resource and Mineral Reserves (2005) which
was prior to the implementation of the current CIM standards for
mineral resource estimation (as defined by the CIM Definition
Standard on Mineral Resources and Ore Reserves dated May 10, 2014).
The key assumptions, parameters and methods used to prepare the
Historical Estimate on Toiyabe are described in the 2009 Technical
Report. While Westward considers the Historical Estimate on Toiyabe
disclosed in this news release to be relevant to investors, it
cautions readers that it should not be unduly relied upon in
drawing inferences on the mineralization on Toiyabe, as additional
work is required to upgrade or verify the Historical Estimate as a
current mineral resource. This additional work includes (but may
not be limited to): re-sampling and re-assaying of available core
and/or pulps, verification of assay certificates and digital assay
data, verification of select drill hole collars, review and
verification of drill hole geologic logs versus the preserved core
and RC cuttings, incorporation of AuCN assays to provide a general
understanding of oxide presence, review and verification of
mineralization controls and modelling techniques.
Conclusions and Next
Steps
The initial results of the surveys confirm a large
hydrothermal footprint resulting in alteration of favourable host
rocks, predominantly Wenban and Roberts Mountains Formations. The
hyperspectral data are currently being imported into the Toiyabe 3D
model to determine true lateral extent and provide spatial context
to the distribution of the mineralizing fluid. The data will
continue to inform Westward's technical team during drill targeting
in anticipation of the upcoming 2022 program.
When completed, the model will provide the first 3D
visualization of surface and subsurface data at the projects, with
the goals of identifying and characterizing: (i) gold
mineralization controls, (ii) on-strike and depth extensions to
gold mineralization at the Courtney Zone, and (iii) new drill
targets.
An induced polarization survey has also recently been
completed across the Toiyabe and Turquoise Canyon Projects. Results
are pending and will be imported into the 3D model for comparison
to the airborne and core imaging hyperspectral
campaigns.
