Drill results of up to 1.01 meters of 68.32 g/t AuEq and 0.49 meters of 111.54 g/t AuEq Highlight Potential Resource Expansion Northeast of the Current Gravel Creek Deposit
Western Exploration Inc. (TSX-V: WEX) (OTCQX: WEXPF) is pleased to announce initial assay results from its 2024 core drilling program in the Jarbidge rhyolite north-east of the Gravel Creek resource area at the Company’s wholly-owned Aura gold-silver project, located in Elko County, Nevada.
Highlights of 2024 Drill Program
The drill results in holes WG459 provide further definition to a set of high-grade Au-Ag bearing veins and breccias in the Jarbidge rhyolite adjacent to the Gravel Creek resource area. Assay results from additional core holes and interpretation of oriented core data will be reported in subsequent news releases.
Assay Results Support Potential for Resource Expansion
Western Exploration CEO, Darcy Marud, commented: “Western Exploration is extremely pleased with the initial results of the 2024 drill program, which intersected assay values of up to 75.3 g/t Au and 3,080 g/t Ag in hole WG459. These results support the Company’s belief that high grade veins continue at least 80 meters to the north of the Discovery Section, as reported in January 2024. Oriented core drilling is still ongoing to extend the north/north-west trending vein zone and to connect with multiple high grade Au intercepts identified by wide-spaced legacy holes in an area of approximately 550 meters by 350 meters in size. The Company anticipates that these results will help support the expansion of the mineral resource at Gravel Creek.”
Multiple High-Grade Au-Ag Vein Drill Intercepts Peripheral to the Gravel Creek Deposit
Previous drilling in the Miocene Jarbidge rhyolite to the north-east of the Gravel Creek deposit intersected multiple high-grade Au-Ag bearing vein intercepts, with individual assays of up to 237.0 g/t AuEq in hole WG379 and 2,800.0 g/t Ag in hole WG456. None of these Jarbidge-hosted intercepts have been included in previous resource estimates. Oriented core drill results from the Company’s 2023 drilling program provided the first set of data that the Company has used to begin linking vein intercepts, with a preliminary interpretation of vein trends shown on the Discovery Section 500N (see Figure 1 below).
Four oriented core holes totaling 2,789 meters have been completed during the 2024 drill program, with hole WG462 currently in progress 160 meters north of the Discovery Section. Hole WG459 was drilled 80 meters to the north of the Discovery Section on section 580N (see Figure 2 and Figure 3 below). The hole intersected multiple quartz-pyrite marcasite-bearing veins and breccias, highlighted by an upper and lower vein/breccia/stockwork zone containing intercepts of over 60.0 g/t AuEq, surrounded by lower grade mineralization. Significant assay intercepts are summarized in Table 1 with drill hole coordinates included in Table 2. Oriented core data is being interpreted as drilling proceeds and will be reported in future news releases.

Significance for Future Gravel Creek Exploration
Result are pending for holes WGC458, WGC460 and WGC461, with hole WGC462 currently in progress. Initial results from hole WGC459 help support the extension of oriented core drilling into the 550-meter by 350-meter area to the northeast of the Gravel Creek resource within the Jarbidge rhyolite with the aim of linking multiple high grade AuEq intercepts in widely spaced legacy holes located in that area. Of note are the number of intercepts of over 10.0 g/t AuEq intersected in the farthest east/north-east drill holes, which suggests that the Gravel Creek system has not been closed off (see Figure 4 below). The 2024 drill results will be evaluated in context with legacy drilling, with the goal of defining a preliminary inferred resource to expand the Gravel Creek deposit resource base.
About the Aura Project
The 6,000-hectare Aura Project has an established mineral resource estimates in three different deposits (Doby George, Gravel Creek and Wood Gulch) (see Table 3 below), as reported in the technical report entitled “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) that was prepared for the Company by Mine Development Associates. The mineral resource estimate included in the Technical Report were prepared in accordance with the requirements of National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
In addition, 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 land through a mineral lease agreement with a local landowner and may purchase those fee lands at any time for the development of Doby George.

Qualified Person Approval
The scientific and technical content in this news release has been reviewed 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 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 warehouse/logging facility in Mountain City and washed, photographed and logged by company geologists. Sample intervals were marked and recorded. Quality control (QC) samples were inserted at regular intervals in the sample stream with all sample shipments, including blanks, core duplicates and reference materials, to monitor laboratory performance. Core was kept in the secure Mountain City facility until transported for assay.
Drill core samples were transported by Neilsen Exploration to ALS Chemex located in Sparks, Nevada, for sample preparation and analysis. Core was sawed at the ALS facility, with ½ prepared for assay and ½ core preserved and returned to Western’s Mountain City facility. Samples were analyzed for gold using ALS Chemex fire assay procedure Au-AA13, with over limits being analyzed by Au_GRA21. Samples were analyzed for silver and a 40-element suite using ALS Chemex procedure ME-ICP41, with over limits being analyzed by Ag_GRA21. Split core, all pulps and select rejects are returned to Mountain City for secure long-term storage.
Oriented core data was collected following methodology established by Oriented Targeting Solutions. Oriented Targeting Solutions compiled data in Access and completed the first pass interpretation utilizing Leapfrog software.
