Western Exploration Files NI 43-101 Technical Report for the Aura Gold Silver Project

Reno, Nevada--(Newsfile Corp. - June 25, 2025) - Western Exploration Inc. (TSXV: WEX) (OTCQX: WEXPF) (the "Company" or "Western Exploration") has filed on SEDAR+ a technical report prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") on the Aura Project ("Aura" or the "Project"), titled "Preliminary Economic Assessment of the Doby George Deposits and Updated Resource Estimate for the Gravel Creek Gold-Silver Deposits, Aura Gold-Silver Project, Elko County, Nevada" (the "Technical Report"). The Technical Report supports disclosures dated May 8, 2025, titled "Western Exploration Announces Positive Preliminary Economic Assessment for the Doby George Resource at The Aura Project" and June 23, 2025 titled "Western Exploration Announces 54% Increase In Inferred Gravel Creek Gold Equivalent Mineral Resources". There are no material differences in the Technical Report from the results disclosed in the May 8, 2025 and June 23, 2025 news releases.

Highlights of the updated Gravel Creek MRE include:

• A significant increase in grades and ounces, at a 3.0g AuEq/t cutoff^*, in the inferred mineral resource category, reflecting the positive contribution from the high-grade vein discovery hosted in Jarbidge rhyolite east of Gravel Creek.

  • Increased ounces of gold in the inferred mineral resource category from 367,000 ounces Au to 571,000 ounces Au, representing a 56%* increase in ounces of gold and a 9% increase in grade of gold.

  • Increased ounces of silver in the inferred mineral resource category from 5,307,000 ounces Ag to 9,726,000 ounces Ag, representing an 83%* increase in ounces of silver and a 28%* increase in grade of silver.

• Indicated gold equivalent grade, reported at a 3.0 g/t Aueq cutoff^*, remained relatively constant between 2021 and 2025 with 216,000 ounces Au and 3,367,000 ounces Ag being reported in the current MRE.

Highlights of the updated Doby George Heap Leach PEA include:

• Base Case After-tax NPV of US$70.7M and an IRR of 25.4% using a gold price of US$2,150 increasing to US$211.2M with a 62.2% IRR utilizing a US$3,000/oz gold price (see upside metal price to base case metal price comparison in Table 1)

• Total Life-of-Mine ("LOM") after-tax net cash flow of US$271.2M over a five-year project life using US$3,000 gold price

• Average annual operating cash flow of $112.1M and a less than 18-month payback period using US$3,000 gold price

• LOM all-in Sustaining cost of US$1,197 per ounce at US$3,000 gold price and US$1,152 per ounce at the base case of gold price being US$2,150

• LOM average grade of 1.01 g/t Au creating potential for significant profit margins

• Estimated pre-production capital costs of US$115.2M excluding upfront Working Capital of US$12.4M which is credited back to the operation on year five

The Technical Report was prepared by RESPEC Company LLC ("RESPEC") and Kappes, Cassidy & Associates ("KCA") both based in Reno, Nevada with an effective date of June 17, 2025. The Technical Report can be found on the Company's website at and on SEDAR+ at under the Company's issuer profile.

2025 Exploration Plan

Exploration will continue in 2025 with an approximate 4,000 meter drill program focused on the Tomasina Fault Zone at Wood Gulch. Wood Gulch is a former producing open pit mine and geological reinterpretation based on prior drill results has reprioritized Wood Gulch as a highly prospective target. While Wood Gulch is the focus of Western Exploration's 2025 exploration program, the significant resource increase at Gravel Creek (as described in this news release) supports a more extensive drill program aimed at infill drilling and resource expansion. In addition, the Company will continue to de-risk the project through project refinement, both in terms of potential processing and cost parameters, continued geotechnical work, ongoing environmental studies, and permit planning.

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 CIM Definition Standards for Mineral Resources & Mineral Reserves prepared by the CIM Standing Committee on Reserve Definition, which is 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.
