Highlights:
- KLM Geophysics has initiated a 33.0-kilometer IP geophysics program to test extensions of mineralization in the Doby George and Wood Gulch/Gravel Creek resource areas, as well as new targets in the Maggie Summit area. The data derived from this program will provide the Company with the information needed to better define future drill targets, with the goal of expanding the existing gold and silver resources across the project. The Company anticipates that KLM Geophysics will complete the program by mid-August 2023.

Major Drilling is scheduled to begin a 2,000-meter diamond core drill program at Gravel Creek on August 1, 2023. The program will test a north-east trending structural corridor hosting high-grade (up to 40.05 g/t Au and 1,951 g/t Ag) low sulfidation epithermal veins in the
Jarbidge rhyolite peripheral to the Gravel Creek resource. Au-Ag-As-Sb-Mo anomalies in soil and rock geochemistry extend up to 2.0 kilometers to the north-east of the Gravel Creek resource along the same trend, suggesting further exploration potential.
Western Exploration CEO, Darcy Marud, commented: "We are excited about the initiation of the 2023 Aura Project exploration program. Data compilation and targeting by Western Exploration, GoldSpot and Geomax over the past year has refined mineralization controls and identified multiple targets that may expand the current Aura Project resource base near Doby George and Wood Gulch/Gravel Creek, as well as hold potential for new generative discoveries in the Maggie Summit area. Previous IP surveys were very successful in outlining the Gravel Creek deposit and we are excited to see results as we extend the technique into other areas of the project.
Secondly, detailed structural mapping in combination with oriented core data collected in 2020, has confirmed that there is a strong north-east orientation to many of the veins hosted within the
PROJECT BACKGROUND AND CURRENT WORK
During the 2023 field season, Western Exploration is focused on completing the following exploration activities at the Aura Project:
- Execute the IP geophysics program with the goal of defining and expanding the already extensive list of targets for drilling on site, including targets surrounding the area comprising the mineral resource estimate outlined in the Aura Technical Report.
- Metallurgical test work at Doby George will continue with column test work results. Bottle roll results indicate that the Doby George material can be recovered via a heap leach process.
- Execute the Gravel Creek drill program with the goal of expanding the north-east portion of the Gravel Creek deposit that are not included in the existing resource. Results from the Gravel Creek drill program will be provided as they become available.
About the Aura Project
Western Exploration is the
Metallurgical test work for all three deposits has shown that well-established processes, including whole mineralization flotation at Gravel Creek and heap leaching at Wood Gulch and Doby George, can be used to extract gold and silver from the known mineralization. A synthesis of exploration work conducted at the Aura Project from 1997 to 2021 has resulted in the creation of a robust geologic model, which offers significant potential for resource expansion and new discoveries on the project.
Doby George is one of the highest-grade, undeveloped open pit heap leach resource in
Wood Gulch and Gravel Creek are located 8 kilometers to the east of Doby George and both occur in a similar geological environment along steep dipping north-west and north-east trending structural zones intersecting a low angle contact between Paleozoic sedimentary rocks and Tertiary volcanics. The mineralization is related to the Tertiary volcanism and has been traced by surface mapping, sampling and drilling over an area of 5.0 kilometers by 3.5 kilometers. Drilling in 2023 will focus on the north-east extension of the Gravel Creek deposit where numerous high grade vein intercepts remain open and outside of the current resource estimate included in the Aura Technical Report (see the news release of the Company dated March 6, 2023, entitled "Western Exploration Announces Additional Exploration Results at Gravel Creek" and Figure 2 below).
The Aura Project is accessible year-round by highway and county roads with access to water and electricity nearby. It is located 32 kilometers north of the Jerritt Canyon mine (see Figure 3 below).

The mineral resource estimate for the Aura project is disclosed in the Company's technical report, prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101"), entitled "2021 Updated Resource Estimates and Technical Report for the Aura Gold-Silver Project,

Qualified Person Approval
The scientific and technical content in this news release has been reviewed and approved by Mark Hawksworth, General Manager of the Aura Project, and a "qualified person" within the meaning of NI 43-101.
Quality Assurance / Quality Control
Legacy drill intercepts are reported at 5.0 g/t Au cutoff, with assays uncut. Exploration 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. Standards and blanks are inserted approximately every 20th sample into the sample stream for QA/QC purposes by the Company as well as the lab. Surface geochemical samples are generally only at anomalous levels and are never used in resource calculations. However, professionally prepared standards were inserted into the sample sequence submitted to ALS CHEMEX to maintain control on assays for comparison purposes. Please see below under the heading "Cautionary Note Regarding Forward-Looking Information" for further details regarding the risks facing Western Exploration.
For additional information on the Aura Project, please see the Aura Technical Report, which has been prepared in accordance with the requirements of NI 43-101, a copy of which is available on SEDAR (www.sedar.com) under Western Exploration's issuer profile and on Western Exploration's corporate website (www.westernexploration.com).
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
