DRILL HIGHLIGHTS
- DGC789 intersected 20.88 meters of 1.41 g/t and 23.63 meters of 3.27 g/t Au, including 7.32 meters of 5.27 g/t Au.
- DGC790 intersected 54.56 meters of 2.08 g/t Au, including 6.4 meters of 4.70 g/t Au.
Darcy Marud, Chief Executive Officer and Director of Western Exploration, commented: "The first two drill holes completed at Doby George demonstrate the remarkable continuity and tenor of near surface oxide gold mineralization and support our assumption that Doby George can be a high-quality, high-grade oxide gold deposit. Importantly, wide zones of higher-grade mineralization offer potential to expand the current resources, not only within the oxide zone but also at depth within the unoxidized part of Doby George."
The complete results for DGC789 and DGC790 are reported below in Table 1. Assay results for the remaining seven drill holes are pending.

DGC789 AuCN/AuFA ratios range from 80 to 113%, based on 26 samples; DGC790 AuCN/AuFA ratios range from 55 to 115%, based on 32 samples, with only three samples below 80%; all AuCN values were capped at 100% of the AuFA assays. |
All sample intervals were assayed by both fire assay (AuFA) and cyanide soluble shake tests (AuCN) followed up by atomic absorption finish. The AuCN results are a measure of the solubility of Au in dilute CN solutions and the state of oxidation of the samples. An AuCN/AuFA ratio of greater than 80% generally indicates strong oxidation and good cyanide extraction potential.
DRILL PROGRAM DETAILS
The Phase 1 drill program was comprised of nine large diameter (PQ) core holes which were completed between July 26, 2022 and September 12, 2022. The drill holes were located at eight different drill sites for a total of 1,138 metres at the Doby George deposit (see Figure 1 and Table 2 below).
The purpose of the Phase 1 drill program was to evaluate areas within, and adjacent to, the current resource boundary to:
- validate and delineate current mineral resources;
- locally test for the expansion potential and structural controls on mineralization;
- provide samples for metallurgical test work to outline leach kinematics, as well as mineralized material and waste rock characteristics; and
- expand upon geotechnical studies through additional test work.

Holes DGC789 and DGC790 were completed in the West Ridge resource area of Doby George, which accounts for approximately 82% of the current mineral resource estimate at Doby George. The drill holes are approximately 440 meters apart and showed very positive grade distribution when compared to the resource block model prepared for the Company by Mine Development Associates and contained in the technical report titled "2021 Updated Resource Estimates and Technical Report For the Aura Gold-Silver Project, Elko County, Nevada" dated October 20, 2021 (with an effective date of October 14, 2021) (see Figure 2 and Figure 3 below) (the "Technical Report"). A copy of the Technical Report is available on SEDAR (www.sedar.com) under Western Exploration's issuer profile.
Once assays results have been received for all nine drill holes completed in connection with the Phase 1 drill program, McClelland labs will commence certain heap leach and column leach test work with the previously crushed and assayed samples. The Company expects to receive the results of all metallurgical test work at the start of Q2 2023.
About Doby George
Doby George is one of the highest-grade, undeveloped open pit heap leach resources in Nevada and one of three mineral deposits on Western Exploration's 100% owned Aura Project. The Aura Project is located 32 kilometers north of the Jerritt Canyon mine, which has been in continual operation since 1981. The deposit is an outcropping, high-grade sediment-hosted mineral deposit, with multiple zones of mineralization identified by drilling in a 1.7 x 0.8 km area (see Figure 4 below). The zone of oxidation extends approximately 150 to 200 meters below surface, while limited deep drilling has encountered unoxidized gold mineralization at depths of over 600 meters below surface.
Homestake Mining Company initially discovered the deposit in the mid-1980s. Since that time, 827 drill holes have been completed, totaling 115,197 meters of drilling. This includes 74 drill holes, totaling 22,622 meters that were drilled by Western Exploration LLC between 1998 and 2017. Metallurgical test work completed on oxidized material by Homestake Mining Company, Independence Mining Company, and Atlas Precious Metals Inc., has indicated favorable metallurgy for standard cyanide heap leach processing. Results from the previous metallurgical testing completed on 52 bottle rolls and 23 column leach samples indicate that heap leach gold recoveries approaching seventy percent can be expected via a crush of 1 to 1.5 inches.
In addition to an established mineral resource estimate (as determined in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101")), the Aura Project has well established infrastructure including year-round accessibility by highway and county-maintained road and nearby access to water and electricity (see Figure 5 below). Western Exploration has exploration, development, and mining rights on 930 hectares of privately owned fee lands through a mineral lease agreement with a local landowner and may purchase those fee lands at any time for the development of Doby George.
The 6,000-hectare Aura Project is unique in the junior mining space insofar as resources have been identified in three different deposits (Doby George, Gravel Creek and Wood Gulch), as supported by the Technical Report (see Table 3 below).

Qualified Person Approval
The scientific and technical content in this news release has been reviewed, prepared and approved by Mark Hawksworth, General Manager of the Western Exploration's Aura Project, who is a "qualified person" within the meaning of NI 43-101.
Quality Assurance – Quality Control
Drill program design, Quality Assurance/Quality Control ("QA/QC") and the interpretation of results is performed by qualified persons employing a QA/QC program consistent with NI 43-101 and industry best practices.
Drill core samples were delivered by Major Drilling to Western Exploration's secure warehouse/logging facility in Mountain City and washed, photographed and logged by company geologists. Quality control (QC) samples are inserted at regular intervals in the sample stream, including blanks and reference materials with all sample shipments to monitor laboratory performance.
Drill core samples are transported by Neilsen Exploration to McClelland Laboratory Inc. located in Sparks, Nevada, for sample preparation and analysis. Each interval is removed from the core box, weighed and crushed using a jaw-crusher to an approximately 2" top size. The crushed interval is blended by repeated coning and is quartered to obtain a one-quarter split for finer crush. Each one-quarter split is crushed to 10 mesh (2 mm) and split to obtain 0.25 – 0.50 kg for pulverization. For fire assays, the 0.25 kg split is pulverized to >95%-150 mesh (106µm). Analysis for gold and silver is completed using a 30-gram fire assay with AA finish. For the CN soluble tests, A 10-gram aliquot of sample (>95%-106 µm) is leached by shaking in a 50 mL test tube for 1 hour, at ambient temperature and 33.3% solids, using a solution of NaCN (5.0 gpL) and pH > 11.0 using NaOH. The solution is separated by centrifuging. Clear solution is analyzed by AA for gold.

This news release may contain "forward-looking information" and "forward-looking statements" within the meaning of the applicable Canadian and United States securities legislation (collectively, "forward-looking statements"). These forward-looking statements, by their nature, require the Company to make certain assumptions and involve known and unknown risks and uncertainties that could cause actual results to differ materially from those expressed or implied in such forward-looking statements. Any statement that involves predictions, expectations, interpretations, beliefs, plans, projections, objectives, assumptions, future events or performance (often, but not always, using phrases such as "expects", or "does not expect", "is expected", "interpreted", "management's view", "anticipates" or "does not anticipate", "plans", "budget", "scheduled", "forecasts", "estimates", "potential", "feasibility", "believes" or "intends" or variations of such words and phrases or stating that certain actions, events or results "may" or "could", "would", "might" or "will" be taken to occur or be achieved) are not statements of historical fact and may be forward-looking information and are intended to identify forward-looking information. This news release contains the forward-looking information pertaining to, among other things: the focus and results of the Phase 1 drill program; the Doby George deposit being located in one of the most favourable mining jurisdictions in the world; Doby George being one of the highest grade, underdeveloped open pit heap leach resource in northeast Nevada; the accuracy of results from prior exploration activities conducted at the Aura Project; the key assumptions, parameters and methods used to estimate the mineral resource estimate disclosed in this news release; the prospects, if any, of the Doby George and Wood Gulch-Gravel Creek mineral deposits; future drilling at the Aura Project; the significance of historic exploration activities and results; and the ability to expand the existing mineral resources at the Aura Project. Such factors include, among others, risks relating to the ability of exploration activities (including drill results) to accurately predict mineralization; errors in management's geological modelling; the ability of Western Exploration to complete further exploration activities, including drilling; property and royalty interests in respect of the Aura Project; the ability of the Company to obtain required approvals; the results of exploration activities; risks relating to mining activities; the global economic climate; metal prices; dilution; environmental risks; and community and non-governmental actions. Although the forward-looking information contained in this news release is based upon what management believes, or believed at the time, to be reasonable assumptions, Western Exploration cannot assure shareholders and prospective purchasers of securities of the Company that actual results will be consistent with such forward-looking information, as there may be other factors that cause results not to be as anticipated, estimated or intended, and neither Western Exploration nor any other person assumes responsibility for the accuracy and completeness of any such forward-looking information. Western Exploration does not undertake, and assumes no obligation, to update or revise any such forward-looking statements or forward-looking information contained herein to reflect new events or circumstances, except as may be required by law.
This release uses the terms "mineral resources", "indicated mineral resources" and "inferred mineral resources". Mineral resources that are not mineral reserves do not have demonstrated economic viability. You should not assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. Further, inferred mineral resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. On October 31, 2018, the SEC adopted new mining disclosure rules ("S-K 1300") that are more closely aligned with current industry and global regulatory practices and standards, including NI 43-101, although there are some differences in the two standards. Accordingly, information concerning mineral deposits contain in this release may not be comparable with information made public by U.S. companies that report in accordance with S-K 1300.
