Barksdale Resources Corp. (TSX-V: BRO) (OTCQB: BRKCF) (FSE: 2NZ) has released assays from the Company’s Spring 2025 drill program with encouraging results and copper grades and provides an update on the Phase ll drill plan to bring the Sunnyside project ownership to 67 ½%.

Phase ll Drill Campaign

The Company remains on track with its Phase ll drilling program which will increase the Company’s ownership of the Sunnyside joint venture with Great Basin Metals to 67 ½%. Due to drill contractor availability, this campaign is being moved to calendar Q1 of 2026. The Phase ll program was previously referred to as the Fall Drill Program. The earn in requirement requires a 7,260 metre (25,000 feet) drill program plus a stock issuance and cash payment, with other requirements already fulfilled.

Spring 2025 Additional Assay Update

The sampling protocol for the Spring 2025 reverse circulation drill program was based on visual inspection of the drill chips for sulfide content. Intervals with observed sulfide content were sent for analysis while intervals without a visible sulfide content were held back. Many of the assay results were open-ended, i.e., the entire interval was mineralized, suggesting that the mineral interval was understated and additional analysis should be performed on the adjacent samples.

A total of 265 additional samples from the open-ended intervals were sent for analysis to ALS Chemex in Tucson, AZ, and the updated, comparative results are presented in Table 1 and drill hole locations are presented in Table 2.

Table 1. Spring 2025 initial and follow-up assay results. Sample depths are listed in metres and feet. True widths unknown. Collar locations listed in Table 2.

The results of the additional sampling show wider intervals with higher copper grades in SUN25-001 and 002, wider intervals and with slightly lower zinc grades in SUN25-002, and a much wider interval, 16.7m versus 3.0m of similar, 0.15% copper grade in SUN25-003.

William Wulftange, CEO of the Company, commented, “The known copper and zinc endowment at Sunnyside continues to expand into new areas previously untested by the Company as supported by the expanded results. Two important conclusions can be drawn from this observation. First, our knowledge and the boundaries of the mineral systems continue to grow with each drill hole, and second, we need to assay most if not all the drill intervals when completing exploratory drilling.”

Other Corporate Updates

Barksdale CEO William Wulftange met last week with the Company’s Sunnyside joint venture (JV) partner, Great Basin Metals CEO Greg Thomas along with Andrew Turner of APEX Geosciences at the Sunnyside project in Patagonia, Arizona, to review drill core and collect samples from the Phase I drill programs. The samples collected by APEX will be assayed to confirm several mineral intercepts reported by Barksdale during the drill campaigns and will be included in an updated
