Vancouver, Oct. 18, 2022 - Westward Gold Inc.
(CSE:WG), (OTC:WGLIF), (FSE:IM50) ("Westward" or the "Company") is pleased to announce results from the Company's inaugural drilling campaign at its flagship Toiyabe Project in Lander County, Nevada ("Toiyabe"). In total, the Company completed ~3,850 meters of reverse-circulation ("RC") drilling across 13 vertical holes and 3 main target zones, all of which were outside of the footprint of the historical resource estimate at Toiyabe (~173 koz at 1.2 g Au/t)(1) (the "Historical Estimate"). See Figure 1 below for collar locations of all the drillholes completed in Westward's 2022 campaign.
Hole T2210 - a 250-meter southwesterly step-out from legacy drillhole(2) T902 (42.7 meters of 1.37 g Au/t) - intersected a vertically-continuous mineralized zone consisting of 50.3 meters of 0.34 g Au/t (including 3.1 meters of 1.57 g Au/t), confirming the discovery of an important gold-bearing structural horizon at Toiyabe.
With T2210, seven drillholes now define a zone of gold mineralization that is ~150 meters by ~410 meters laterally, and up to ~50 meters thick (the "SSD Zone")
Mineralization is hosted within a favorable stratigraphic sequence known as the Wenban Formation - a key gold host at the nearby Pipeline and Cortez Hills deposits - and is associated with a blind thrust fault, a duplex zone, and an igneous dike / sill corridor
Westward believes the SSD Zone represents a new, emerging gold discovery that is open for expansion in multiple directions, with minimal drilling to-date
Additional Highlights (See Figure 2 for Results Table)
8 of the 13 drillholes (62%) encountered significant gold (defined as 1.5+ meters / 5+ feet of 0.14+ g Au/t), with 4 of those 8 having reportable intervals of 12.2+ meters (40+ feet)
At the California Target (~850-meter westerly step-out from Historical Estimate), drillhole T2202 intersected 13.7 meters of 0.59 g Au/t (including 4.6 meters of 1.15 g Au/t); shallow, near-surface gold mineralization is open in multiple directions
11 of the 13 drillholes (85%) encountered significant silver (defined as 9.1+ meters / 20+ feet of 1.0+ g Ag/t), with 6 of those 11 having reportable intervals of 25.9+ meters (85+ feet)

Dave Browning, Westward's Vice-President Exploration, noted: "Our drill location selection for this campaign was ambitious and included significant step-outs, testing blind targets. Confirmation and expansion of the SSD Zone represents a measurable improvement of our understanding of mineralization at the property, and opens up an abundance of near-term follow-up targets. The vast majority of legacy drilling was shallow, and this thick zone of mineralized material was only encountered in six previous holes."
Steven Koehler, Technical Advisor to the Company, added: "Significant Carlin-type gold discoveries that I've been involved with - including Leeville, Pete Bajo, Turf, and Rita K - have often been preceded by the drilling of thick, lower-grade gold zones. This "smoke", exemplified by T2210, is a common characteristic of larger gold systems. Westward has taken a systematic approach to early-stage exploration, and as the database of geological knowledge continues to grow, so does the potential to vector into a meaningful deposit."

Figure 2: Significant Gold & Silver Intervals
Note: Gold intervals reported in Figure 2 were calculated using a 0.14 g Au/t cut-off; silver intervals reported were calculated using a 1.00 g Ag/t cut-off. Weighted averaging was used to calculate all reported intervals. True widths are estimated at 70-90% of drilled thicknesses.
Toiyabe-Saddle Down-Dip Target ("TSD Target")
Prior to the Company's inaugural drill campaign, legacy data review identified 6 historical drillholes (5 core, 1 RC) which intersected a broad zone of gold mineralization and alteration ~250 meters beneath, and separate from, the Historical Estimate at Toiyabe. The Westward technical team recognized the unique geologic characteristics of this horizon, and began referring to it as the SSD Zone.
Hyperspectral analysis indicated the potential for a northeast-trending tabular zone of mineralization and clay alteration; this was a new revelation which ran counter to many historical cross-sectional interpretations of the property. The TSD Target was chosen (3 drillholes, T2209-T2211) to begin to fill in a 600-meter strike length - between the Historical Estimate and the past-producing Toiyabe-Saddle Mine to the southwest - with no prior drilling.
Legacy diamond drillholes which intersected +1.00 g Au/t material in the SSD Zone included:
T1002: 33.8 meters of 1.16 g Au/t from 292.4 meters
T1601: 25.9 meters of 1.01 g Au/t from 278.4 meters
T902: 42.7 meters of 1.37 g Au/t from 266.7 meters

Gold mineralization observed in prior drilling typically occurs within larger structural zones of broken rock, gouge, oxidation, igneous sills and dikes, and two dominant structural fabrics at 30-50 and 70-80 degrees to the core axis. Structural features are consistent with a compressional environment; thrusts, ramps, and duplexes are present in both historical and 2022 drilling.
Observations from the three 2022 RC drillholes at the TSD Target include:
T2209: 10.7 meters of 3.92 g Ag/t from 233.2 meters to total depth (243.9 meters)
This hole was significantly shallower than both 2210 (324.6 meters) and 2211 (349.0 meters)
Presence of silver mineralization leading up to total depth indicates the hole ended before reaching the gold-bearing portion of the SSD Zone; in other holes, silver was observed both above and below gold intervals
T2210: 50.3 meters of 0.34 g Au/t from 266.8 meters (including 3.1 meters of 1.57 g Au/t from 289.6 meters); 18.3 meters of 2.75 g Ag/t from 222.6 meters; 67.1 meters of 2.63 g Ag/t from 254.4 meters; see Figure 3 above and Figure 4 below
T2211: 3.1 meters of 0.3 g Au/t from 256 meters; 29 meters of 3.00 g Ag/t from 236.2 meters; 50.3 meters of 1.89 g Ag/t from 298.8 meters
Combining Westward's datasets and knowledge to-date, the following observations may offer important guidance for follow-up campaigns:
The SSD Zone remains largely untested, with almost no drilling within a large corridor to the southwest and northeast of historical intervals (see Figure 3 above; grey shaded area represents areas with no prior drilling beyond 125 meters)
Areas beneath the Historical Estimate footprint have also seen no meaningful exploration
Mineralization is open to the northeast; the limited data to-date suggests gold grades strengthen in that direction along strike; more drilling is required to prove this out

Note: Sample depths shown in Figure 4 above were recorded in 5-foot intervals.
Three drillholes (T2201-T2203) were completed with an average step-out distance of ~865 meters west of the reference hole within the Historical Estimate footprint. Both shallow and deep intervals of anomalous gold and silver were encountered in all three holes. The drillholes targeted strong gold- and arsenic-in-soil anomalies proximal to a northeast-striking dike swarm. T2202 intersected 13.7 meters of 0.59 g Au/t, including 4.6 meters of 1.15 g Au/t. Mineralization begins near the current topographic surface and is open in multiple directions.

Note: Sample depths shown in Figure 5 above were recorded in 5-foot intervals. Yellow: 13.7 meters of 0.59 g Au/t (including 4.6 meters of 1.15 g Au/t).
Toiyabe Hills Fault ("TH Fault") Target
The TH Fault is a newly-identified structure, first discovered in late 2021 and later expanded upon through detailed field mapping conducted in 2022. It lies to the east and southeast of the Historical Estimate, striking northeast out of the past-producing Toiyabe-Saddle Mine and towards the Company's Turquoise Canyon Project. Six holes were drilled along the fault trace, with four towards the northern end (T2204-T2208) and two at the southern end (T2212 and T2213); based on available data, the TH Fault had never been tested in any previous campaigns.
Three of the six holes intersected reportable gold, highlighted by T2205 with 12.2 meters of 0.40 g Au/t from 38.1 meters. Five of the six holes encountered significant silver with intervals of at least 18.2 meters (60 feet).
The TH Fault drillholes are characterized by thick zones of decalcification and brecciation in the Wenban Formation (up to 55 meters in multiple holes), abundant intrusive rocks, elevated silver and zinc, oxidation, and repetition of stratigraphy (duplexing); breccia zones are directly associated with elevated gold and silver. Strong decalcification was also observed within the duplex zones. These features indicate that the TH Fault is a hydrothermal and magmatic pathway, and additional drill targets remain along strike to the northeast of 2022 drilling.
The Company will undertake important follow-on analyses over the coming months, in preparation for the next stage of exploration targeting. Future campaigns will incorporate RC and diamond drillholes to test high-priority targets with near-term expansion potential, including the SSD Zone.
Data review is currently ongoing to further the Company's knowledge of the new discovery:
Compilation and modeling of all significant silver intervals from legacy drilling (including a grade-thickness map) to better understand system extent; silver has a demonstrated ability to be a pathfinder to gold mineralization
Creation of multiple grade-thickness maps at various depth horizons to better understand the nature of stacked mineralization and target the blind SSD Zone
Correlation of multielement geochemistry to metal presence (2022 campaign is the first to test a full suite of elements)
Identification of priority historical drillholes to have composite pulps analyzed for multi-element geochemistry
Relogging of legacy RC holes across priority areas
Continued development of a tectonostratigraphic column
Hyperspectral imaging of 2022 RC chip trays
Continuation of 1:5000 detailed Anaconda-style geological mapping to the north and east of Historical Estimate, i.e., potential SSD Zone extent
Additional geophysics (fill-in gravity and CSAMT surveys) to identify SSD Zone expansion drill targets
Quality Assurance / Quality Control ("QA/QC")
The Company implemented a best-practices QA/QC program during the 2022 drilling campaign. All sampling was conducted under the supervision of the Company's Vice President Exploration or Project Geologist and the chain of custody from the project to the sample preparation facility was continuously monitored. Samples were transported directly from site to the ALS Ltd. ("ALS") Sample Prep Facility in Elko, Nevada, and either prepped there or in Chihuahua, MX. Prepared sample pulps were then transported by ALS to their analytical laboratories in either Reno, Nevada, Vancouver, BC, or Lima, Peru.
RC samples were collected every five feet. Certified standards, rig duplicates, or blanks were inserted every 50 feet / 10 samples. All samples were analyzed for gold, silver, copper, and 46 additional elements. Assays consisted of fire assay / ICP (Au - ICP21) for gold, and four acid / ICP-MS (ME-MS61) for geochemistry.
Drill hole deviation for all 13 holes was measured by gyroscopic down-hole surveys with tooling provided by REFLEX of Elko, NV. The deviation surveys provided accurate data about the true inclination and azimuth of the holes. Obtaining an accurate survey of the drillholes leads to a better contextual understanding of the RC samples, and a more robust 3D geological model.
