Beyond Lithium Expands Critical Minerals Portfolio with Strategic Acquisition of the Owl Creek Copper Porphyry Project in British Columbia and Files Amended Offering Document for LIFE Offering

Winnipeg, Manitoba--(Newsfile Corp. - August 12, 2025) - Beyond Lithium Inc. (CSE: BY) (OTCQB: BYDMF) (the "Company" or "Beyond") is pleased to announce that it has applied for a multi-cell mineral claim encompassing approximately 1,566 hectares in an area of southwestern British Columbia hosting several significant porphyry deposits for copper-moly and copper-gold mineralizations, known as Owl Creek # 1 (the "Owl Creek Project"). The project is situated roughly 8 kilometers northeast of the town of Pemberton and benefits from excellent access via upgraded logging roads, including the Owl Creek Forest Service Road.

Allan Frame, CEO of Beyond, commented, "We are very excited that Beyond now holds three high-quality assets in our critical minerals exploration portfolio. The Ear Falls Project in Ontario has proven spodumene mineralization, the Rare One Project in British Columbia hosts rare earth and base metal mineralization, and our new Owl Creek Project shows extensive copper mineralization right from surface. In recent months, our technical team has carefully evaluated several prospective opportunities, prioritizing projects with strong geological fundamentals, significant upside potential, and good road access for extended exploration seasons. We remain committed to exploring for critical minerals in a disciplined geological approach to drive long-term value for our shareholders."

Regional Geology

The Owl Creek Project is located within the regional Cascade Magmatic Arc that spans over 1,200 km from northern California to Canada (Hildreth 2007). The Cascade Magmatic Arc is a post-accretionary arc hosting several significant porphyry deposits for copper-moly and copper-gold mineralizations associated with Miocene intrusions including (Figure 1):

• Mt. Margaret in southwestern Washington State (Ascot Resources Ltd.)⁸

  • Historical geological resources of 523.0 MT at 0.36% Cu, 0.011% Mo, and 0.24gpt Au (CIM Special Volume 37, 1986)

• New Prosperity in south-central BC (Taseko Mines)⁷

  • Total Measured and Indicated Resources at 0.15% Cu cutoff grade with 1,109 MT at 0.24% Cu and 0.007% Mo

Historical Exploration Work & Highlights

• Early 1900s

  • The Owl Creek showing was first discovered as early as 1913 referred as the Copper Queen prospect.

• 1960s to 1970s

  • A 70 meters long adit was developed at the Copper Queen prospect, and an underground chip sampling program resulted 0.33% Cu over 66 meters from the adit (Rastad & Pezzot 2006).

  • Pine Lake Mining completed diamond drillings, soil sampling, and magnetometer and induced polarization surveys (Naylor and Scott 1973)

    • Diamond drill hole around the adit intersected 0.2% Cu over 182m

    • Diamond drill hole in the northwestern area intersected 0.4% Cu over 91.4m

• 2010-2012

  • Surface mapping, grab sampling, and airborne magnetometer survey based on Goldsmith 2011's assessment report and Pezzot 2011's geophysics report (Figure 2.)

    • Grab samples from mapped diorite assayed up to 1.99% Cu

    • Magnetometer survey outlined the NW striking trend and delineated several anomalies in relation to the magnetic signature of mapped mineralized diorite

B.C. Mineral Claims Consultation Framework

In March 2025, the Province of British Columbia introduced the Mineral Claim Consultation Framework in response to a BC Supreme Court ruling, which affirmed the government's duty to consult Indigenous communities prior to registering any mineral claims. Beyond has submitted a mineral claim application for the Owl Creek Project and it is anticipated that the consultation process will be underway by early September 2025.
