NOTE: All finances in Canadian Dollars unless otherwise stated.

Vancouver, British Columbia--(Newsfile Corp. - March 12, 2026) - Barksdale Resources Corp. (TSXV: BRO) (OTCQB: BRKCF) (FSE: 2NZ) ("Barksdale" or the "Company") is pleased to announce that Alford Drilling has completed the first round of the Phase II drill program at the Sunnyside Property in Southern Arizona. A total of 6,000 feet was completed in six holes utilizing two drill platforms over the 20-day shift. Five of the six planned holes reached planned target depths, except for hole SUN26-004R that encountered a strong clay zone and was terminated at 80 feet. Please see Table 1 below.

"The initial Phase II holes have tested the near surface copper mineralization identified by ASARCO's "BB and TM" hole drill programs completed in the 1990s," said Barksdale CEO William Wulftange. "Drill chip logging noted the presence of chalcopyrite, covellite and chalcocite in altered feldspar porphyry within all four drill holes logged to date."

A total of 823 samples were sent to Skyline Assayers Inc. of Tucson, Arizona, for gold fire assay and multielement ICP analysis. All samples were maintained in the Company's secure area prior to shipment; custody was transferred to Skyline at site and then transported by Skyline direct to the laboratory in Tucson.

QAQC Program
Barksdale's QA/QC program for drill samples involves insertion of certified reference material (CRM's) prepared from similar deposit type material and purchased from an industry supplier into the sample stream, collection of a drill duplicate sample for assay and insertion of known sterile or "blank" material to be assayed.
