Barksdale hits 65.5 m of 0.47% Cu, 1.24 g/t Ag at SUN26-013R

Vancouver, British Columbia--(Newsfile Corp. - July 27, 2026) - Barksdale Resources Corp. (TSXV: BRO) (OTCQB: BRKCF) (FSE: 2NZ) (" Barksdale " or the " Company ") is pleased to announce the 2026 drill program at its 51% owned Sunnyside property has exceeded the required 25,000 ft drill requirement stipulated in the Company's joint venture agreement with Great Basin Metals (" GBM ", formerly Regal Resources) paving the way for the Company to increase its ownership to 67.5%. Barksdale has now met all spend and drilling requirements as outlined in the JV Agreement and expects to release the final C$550,000 cash and 4,900,000 share payments upon written confirmation by GBM that all Phase II earn-in requirements have been met. Barksdale CEO William Wulftange comments, "Achieving the Phase II drill footage requirement is a major milestone for the company, nearly nine years in the making".

Wulftange continues, "Barksdale could not have achieved this goal without the unwavering support of shareholders, our Board of Directors, Exploration staff and support personnel. Thank you!" SUN26-013R Drill Results Update The overlimit portion (>10,000 ppm) of four assays from hole SUN26-013R stated as 25 ft of 1.93% Cu from 615 ft to 640 ft were not included in the 615ft to 870ft, 255 ft interval average grade calculations in the July 20, 2026, press release. The updated intervals and average grade calculations are highlighted in Table 1 below.

The Company's geologists, including myself, believe that these four holes taken together likely connect a large zone of copper lode vein mineralization that is continuous over greater than 600m of strike and continues to depths of up to 1,000m. The working hypothesis we have is that the Copper lode veins follow a northwest-southeast structural trend that controls their distribution, and that they are proximally sourced from a much larger porphyry Copper-Molybdenum (Cu-Mo) mineral deposit." The Copper mineralization reported here is hosted in sericitic to advanced argillic-altered quartz monzonite to monzonite porphyry. Alteration is pervasive and intense, consisting mainly of sericite and quartz, overprinted by pyrophyllite, quartz, barite, and locally by later epithermal silicification with quartz veins and veinlets.

This alteration assemblage places the mineralized zone within the upper portion of a porphyry-style mineral deposit. In summary, results received to date, combined with historical data, indicate that the high-grade hypogene copper mineralization, occurring as primary copper sulfides, is part of a porphyry copper system with no apparent supergene enrichment zone or blanket. The results reported here further define a broad, low-grade chalcocite zone surrounding the porphyry and suggest that the high-grade sulfide veins represent the upper expression of deeper Cu-Mo porphyry-style mineralization.
