VANCOUVER, January 08, 2025--( BUSINESS WIRE)--Western Exploration Inc. (TSXV: WEX; OTCQX: WEXPF) (the "Company" or "Western Exploration") is pleased to announce additional assay results from its 2024 core drilling program in the high-grade Jarbidge rhyolite discovery immediately adjacent the Gravel Creek resource at the Company's wholly-owned Aura gold-silver project (the "Aura Project").
Gravel Creek is a new high-grade, Miocene aged, epithermal discovery in the northern Great Basin of Nevada, with assays in 2024 drilling of up to 75.3 g/t Au (WGC459) and 4,630.0 g/t Ag (WGC461). The new high-grade area, located less than 200 meters east of the current Gravel Creek mineral resource, which contains 245k Aueq indicated ounces at 5.81 g/t Aueq and 443k Aueq inferred ounces at 5.02 g/t Aueq (Table 3 Mineral resource estimates for the Aura Project as reported in the 2021 Technical Report), has been tested by only 19 drill holes to date and is open in all directions. It is one of multiple high-grade targets in the Wood Gulch/Gravel Creek area that offers excellent near-term resource expansion potential on the Aura Project.
Significant Resource Expansion Potential
Western Exploration CEO, Darcy Marud, commented: "The 2024 drill program intersected multiple high-grade gold-silver intercepts in all five core holes completed. We are very excited with the results as they met and even exceeded our expectations both in terms of grade and extension of mineralization. Every drill hole to date has returned high-grade results and the two step out holes to the south and north, drill holes WGC458 and WGC462, intersected the Discovery Trend as anticipated and showed the continuation of high-grade precious metals mineralization."
Mr. Marud added "The 2024 drill results support Western Exploration's confidence that the Jarbidge rhyolite and greater Gravel Creek-Wood Gulch area hold significant resource expansion potential in high-grade gold-silver bearing epithermal veins and breccia zones analogous to other Miocene epithermal systems in the northern Great Basin of Nevada."
Highlights from 2024 Exploration Program
- The 2024 drill program consisted of five oriented core holes designed to offset high-grade intercepts encountered in 2023 drilling.
- All 2024 drill holes intersected multiple vein/breccia zones with +10.0 g/t AuEq values defining a minimum of 350 meters of strike and 250 meters of dip length.
- New results are reported here for holes WGC461 and WGC462
- WGC461 was drilled 80 meters up dip to the east on Section BL+500N and reported individual assays of up to 46.1 g/t Au and 4,630.0 Ag, including:
- 1.53 meters @ 19.98 g/t AuEq (10.39 g/t Au and 815.1 g/t Ag)
- 0.85 meters @ 21.26 g/t AuEq (4.08 g/t Au and 1,460 g/t Ag)
- WGC462 was drilled 180 meters north of the Discovery Section on Section BL+680N and reported individual assays of up to 24.5 g/t Au and 1,070 g/t Ag, including:
- 1.13 meters @ 12.0 g/t AuEq (8.24 g/t Au and 318.9 g/t Ag)
Multiple rhyolite-hosted high-grade Au-Ag drill intercepts peripheral to the Gravel Creek Resource
Previous drilling in the Miocene Jarbidge rhyolite to the east of the Gravel Creek deposit intersected multiple high-grade Au-Ag bearing vein intercepts, with individual assays up to 237.0 g/t Au (WG379) and 2,800 g/t Ag (WG456). None of these Jarbidge-hosted intercepts have been included in previous resource estimates. To follow up on these intercepts, five oriented core holes totaling 3,556 meters were drilled as 80-meter step outs in the 2024 Gravel Creek drill program. (Figure 1). Results for holes WGC461 and WGC462 are reported here, while results for holes WGC458 to WGC460 were previously reported in news releases of the Company dated October 7, 2024 (entitled "Western Exploration Reports Positive Assay Results From 2024 Drilling Program at Gravel Creek") and November 11, 2024 (entitled "Western Exploration Reports Additional High Grade Assay Results From 2024 Drilling At Gravel Creek").
Hole WGC461 was drilled on Discovery Section 500N, 80 meters up dip from hole WGC456 (Figure 1 and Figure 2). Hole WGC462 was drilled on Section 680N, approximately 100 meters north of holes WGC459 and WGC460 (Figure 1 and Figure 3). Both holes intersected multiple quartz-pyrite marcasite-bearing veins and breccias along the projected Discovery Section trend, with multiple intercepts over 10.0 g/t AuEq. Significant assay intercepts are summarized in Table 1 with drill hole coordinates in Table 2.

Significance for Future Gravel Creek Exploration
Results from 2024 core drilling confirms there are multiple vein-breccia zones with +10.0 g/t AuEq values within the projected structural corridor in the Jarbidge rhyolite east of the Gravel Creek resource (Figure 4). Drilling has been successful, with all oriented core holes drilled in 2023-2024 intersecting multiple zones with +10.0 g/t AuEq mineralization. Multiple high priority targets are present along dip and strike both to infill and extend mineralization. The 2024 drilling gives further confidence to expand oriented core drilling into and beyond the 550-meter by 350-meter area east of Gravel Creek that hosts multiple high grade AuEq intercepts in widely spaced legacy holes, as the system appears open for expansion.
Of broader significance, Figure 5 shows that the Gravel Creek area is a small portion of a zone of favorable structures and hydrothermal alteration at least 2.5 x 4.0 kilometers in size, with multiple targets with resource expansion potential that have received limited to no exploration drilling.
ABOUT THE AURA PROJECT
The 6,000-hectare Aura Project has established mineral resource estimates in three different deposits (Doby George, Gravel Creek and Wood Gulch), as described 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 "Technical Report"; see Table 3 below). The mineral resource estimates in the Technical Report were established in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101").
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 6 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.

Cautionary Statements Regarding Estimates of Mineral Resources
This news release uses the terms measured, indicated, and inferred mineral resources as a relative measure of the level of confidence in the resource estimate. Readers are cautioned that mineral resources are not mineral reserves and that the economic viability of resources that are not mineral reserves has not been demonstrated. The mineral resource estimate disclosed in this news release may be materially affected by geology, environmental, permitting, legal, title, socio-political, marketing, or other relevant issues. The mineral resource estimate is classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum's "CIM Definition Standards on Mineral Resources and Mineral Reserves" (CIM) incorporated by reference into NI 43-101. Under NI 43-101, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies or economic studies except for preliminary economic assessments. Readers are cautioned not to assume that further work on the stated resources will lead to mineral reserves that can be mined economically.
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.
Cautionary Note Regarding Forward-Looking Information
