BARKSDALE COMPLETES PHASE II EARN-IN TO REACH 67.5% OWNERSHIP OF SUNNYSIDE; ADVANCES SAN JAVIER GOLD WORK

Barksdale Resources Corp. completed final cash and share payments to Great Basin Metals Inc., formerly Regal Resources Inc., were completed on Aug. 28, 2026. On that date, the company paid $550,000 in cash and issued 4.9 million common shares to Great Basin in satisfaction of the remaining phase II earn-in requirements. The common shares issued to Great Basin are subject to a four-month hold period from the date of issuance, in accordance with Canadian securities legislation. As such, the company's ownership percentage of Arizona Standard LLC, holding company of the Sunnyside property located in the Patagonia mining district of southern Arizona, has increased from 51 per cent to 67.5 per cent and Great Basin's ownership has decreased from 49 per cent to 32.5 per cent.

Barksdale chief executive officer William Wulftange commented: "Reaching 67.5-per-cent ownership is a major accomplishment for Barksdale and I congratulate all involved. We now look forward to working with the Great Basin delegates to forge a common path forward at Sunnyside, a project we believe has the potential to host a significant copper system in Arizona."

Management committee and joint financing

As of Aug. 28, 2026, Arizona Standard's Sunnyside property will be operated under the direction of a management committee chaired by Barksdale, composed of three delegates representing Barksdale and two delegates representing Great Basin. All approved spending will be financed based on the 67.5-per-cent and 32.5-per-cent ownership percentages. The company intends to present an initial budget to the management committee in early September, 2026, which would provide for completion of the fall 2026 diamond drill program, an airborne ZTEM (Z-tipper electromagnetic) survey over the property and other supporting expenditures. Approval of the budget and the timing of any work program are subject to the approval of the management committee.

Under the Arizona Standard joint venture agreement, each member is required to finance approved expenditures in proportion to its ownership interest. The agreement sets out the timing of contributions and the consequences where a member does not finance its share. The agreement also governs the composition and operation of the management committee.

San Javier

The property option agreement between Barksdale (and its subsidiary, Estrella de Cobre SA de CV) and Tusk Exploration Ltd. (and its subsidiary San Javier de Cobre SA de CV) to purchase 100 per cent of Tusk Exploration's San Javier property was executed on Sept. 22, 2020, and included 12 named concessions. All required cash and share payments are paid and transfer of the 12 concession titles is under way.

The resampling of 2007 drill core rejects for gold content returned very favourable results as announced in the company's July 30, 2026, press release. The next step is to identify 2026 and 2007 drill core material that can be sampled for column and/or bottle-roll tests to determine estimated recoveries of the gold present at San Javier. This precursor work is a key step in estimating an initial gold resource and determining potential recovery methods.

Barksdale Resources is a base metal exploration company headquartered in Vancouver, B.C., that is focused on the acquisition, exploration and advancement of highly prospective base metal projects in North America. Barksdale is currently advancing the Sunnyside copper-zinc-lead-silver project and the San Antonio copper project, both of which are in the Patagonia mining district of southern Arizona, as well as the San Javier copper-gold project in central Sonora, Mexico.
