Barksdale to Raise Stake in Sunnyside Project to 67.5%

Barksdale Resources Corp. Eyes Expansion at Sunnyside Project Following Promising Drill Results

All figures are in Canadian dollars.

Vancouver, British Colombia – Barksdale Resources Corp. (TSXV: BRO) is gearing up for an ambitious fall drill program at its Sunnyside project, aiming to capitalize on promising preliminary results from its spring drilling campaign. The company, which recently completed the necessary spending and drilling to maintain a 51% interest in the project, is now poised to increase its ownership to 67.5%.

According to Barksdale’s CEO, William Wulftange, the Sunnyside project holds significant potential, encompassing extensions of South32’s Taylor and Peake deposits, a large, unconfirmed copper porphyry deposit, and a near-surface chalcocite target. Historical drilling data, including those done by ASARCO, have revealed compelling copper mineralization targets both near the surface and at greater depths.

“We are excited to move towards 67.5% ownership of the Sunnyside project,” said Mr. Wulftange. “The undeveloped targets at Sunnyside offer a low-risk, high-reward opportunity that warrants careful testing and resource estimation.”

The company’s confidence stems from several key factors:

• The Patagonia District’s size and potential are comparable to other significant mining districts.
• The Sunnyside property hosts the extensions of the Taylor and Peake deposits.
• The Hermosa Property’s development promises valuable underground access to the porphyry deposits.
• ASARCO’s historical Sunnyside drilling has unveiled both a deep porphyry target and a near-surface Chalcocite Zone, with strong copper mineralization intercepts.
• Preliminary spring drilling assays have confirmed copper mineralization 375 meters east of ASARCO’s drilling. Drilling costs were a notably low $78.00 per foot.

Spring Drill Program: A Glimpse of Potential

The spring drill program has offered a glimpse into the Sunnyside project’s potential. Results from the program confirm copper mineralization, with intersections returning up to 0.78% copper over 4.6 meters (15 feet), alongside lower-grade intervals throughout the zone. The drilling extended the known mineralized zone and also showed a transition from copper-rich mineralization to zinc and lead at deeper levels, which may be influenced by underlying CRD base metal deposits. Additional samples are being analyzed, with results expected in July.

Select intervals from the Spring 2025 Sunnyside drilling. Based on open-ended intervals, additional samples were sent for analysis, and results are expected in July 2025.

Following the successful spring drill program, Barksdale is moving forward with its plan to increase its stake in the project. The Company is waiting on confirmation from Regal to finalize the $1.0 million cash payment and the release of 5.0 million shares from escrow, after which it will be able to proceed to 67.5% ownership.

Fall Campaign: Drilling Deeper into Opportunity

The fall drill campaign is designed to build on the positive spring results by further exploring both the near-surface chalcocite zone and the porphyry body lying beneath it.

The objectives of the program are two-fold: to begin quantifying a mineral resource and to meet the Phase II earn-in requirements with Regal. This will lead to Barksdale securing the 67.5% ownership stake. The company’s success with its low-cost spring program has allowed them to begin planning the fall program.

Looking ahead, Barksdale is positioned to capitalize on the growing demand for metals essential to the global energy transition. The company is focused on copper and other critical minerals, and its strategic focus could lead to a significant role in meeting future resource needs.
