Barksdale Announces Plan to Increase Sunnyside Project Ownership to 67.5%

Received Preliminary Spring Drilling Assays and Plans for Fall Campaign

Vancouver, British Colombia--(Newsfile Corp. - June 26, 2025) - Barksdale Resources Corp. (TSXV: BRO) (OTCQB: BRKCF) (FSE: 2NZ) ("Barksdale" or the "Company") is pleased to announce that it has completed all expenditures and drilling footage required to maintain a 51% interest in Sunnyside and is awaiting confirmation from Regal Resources ("Regal") to pay the $1.0 million cash and release the 5.0 million Barksdale shares held in escrow.

The Company also announces its decision to increase its ownership of the Sunnyside property to 67.5%. As a result, the Company plans to complete another 7,620 metres (25,000 feet) to surpass the Phase 2 earn-in requirements with Regal. The fall 7,620 metre drill program is expected to start after the rainy season this year and be completed before year-end.

"We are excited to move towards 67.5% ownership of the Sunnyside project for our shareholders as the project contains not only the extensions of South32's Taylor and Peake deposits but both a large, undefined copper porphyry deposit and the near surface chalcocite target," said Barksdale CEO William Wulftange.

"A review of the historical drilling by ASARCO revealed both the near surface and deeper copper/base metal targets that returned very impressive intercepts of copper mineralization (Figure 1, Table 1), which have largely been ignored until now. These undeveloped targets offer low risk and high reward, warranting careful testing and resource estimation. Mining of these deposits could proceed with underground mining methods, avoiding surface disturbance, similar to the South32 complex," added Mr. Wulftange.

The following highlights provide foundational support to the Company's decision to move beyond its initial 51% ownership in the Sunnyside project:

• The Patagonia District is comparable in size and potential to the Pima District in Arizona or the Bingham Canyon District in Utah.

• The discovery of the Clarke, Taylor, and Peake deposits by South32 are important discoveries but are not the only mineral deposits to explore in the Patagonia District.

• The porphyry system responsible for South32's deposits is entirely located on Barksdale's Sunnyside property, along with the extensions of the Taylor and likely Peake deposits (Figure 1).

• The development of the Hermosa Property adds value to Sunnyside and can provide underground access to the porphyry deposits.

• Drilling by ASARCO on the intrusive porphyry at Sunnyside reveals not only a deep large porphyry target but also a near surface Chalcocite Zone (Table 1). Both targets have returned impressive intercepts of copper mineralization.

• Preliminary Spring drilling assays on the Chalcocite Zone target confirm copper mineralization 375 metres (1,230 feet) to the East of the ASARCO drilling (Table 2). Drilling costs of the program were $78.00 per foot representing a substantial reduction in drilling costs over past programs.

Spring Drill Program

The Spring Drill Program results presented in Table 2 below confirm copper mineralization up to 0.78% Cu over 4.6 metres (15 feet) with lower grade values and broader, open-ended intervals dispersed throughout the entire zone. The drilling was done approximately 375 metres east of the ASARCO drilling which significantly extends the known mineralized zone. The results also show a transition from copper rich mineralization at the surface to zinc and lead dominated mineral systems at depth, possibly influenced by the deeper CRD base metal mineralization. Additional samples to extend the mineralized intervals are being prepped for analysis at ALS Chemex 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.

The Company believes it has completed all drill footage and spend requirements under the Phase 1 agreement with Regal to maintain 51% ownership of the Sunnyside Project. The Company has provided all documentation on expended costs and drill footage and has the required $1.0 million payment and 5.0 million shares in escrow. Once acknowledgement is received from Regal, the Company then has 20 days to elect to go to 67.5% ownership of the Sunnyside Project.

Fall Drill Campaign

The Company is planning a Fall Drill program to further test the central and western extents of the near-surface Chalcocite Zone and the first of two copper porphyry bodies directly beneath it.

The objectives of the program are twofold: (1) to begin establishing a mineral resource and (2) to complete over 7,620 metres (25,000 feet) of drilling to fulfill the Phase II earn-in drill footage requirements with Regal. Achieving these objectives will result in the Company acquiring 67.5% ownership of the property, along with fulfilling the necessary cash and stock payments. After completing the successful and low-cost spring drilling, the Company is now able to budget the fall program and is in talks with global drilling companies about financing it through Barksdale equity instead of cash.

Corporate Updates

The Company announced that it has transitioned from the OTCQX market to the OTCQB market in the United States. This move is due to the Company no longer meeting the minimum bid requirements of the OTCQX platform. Barksdale continues to trade on the OTC Markets under the symbol "BRKCF' and the change does not affect trading.

In Barksdale's news release dated May 13, 2025, the Company announced that Ira M. Gostin, of Reno, Nev., had joined Barksdale as the head of investor relations but neglected to mention that Mr. Gostin does not have any interest, directly or indirectly, in Barksdale nor its securities, and does not have any right or intent to acquire such an interest. Further, he is not receiving shares of the Company as compensation.
