Barksdale Resources Defines Continuous Hypogene Copper Mineralization to Over 1,000 Metres Depth and Plans 15,240-Metre Fall 2026 Core Program

Executive Summary

• Barksdale Resources Corp. reports completion of 19 drill holes (20,005 ft) at its Sunnyside Property, demonstrating over 1,000 metres of continuous vertical copper mineralization across hypogene chalcocite targets and historical mine structures.
• The Phase II drill program is scheduled to conclude by early July 2026, with final drilling designed to meet a 25,000 ft threshold that will increase the company's ownership interest in the deposit to 67.5%.
• The company outlined plans for a 15,240-metre Fall 2026 drill program and an airborne TEM geophysical survey, while pending assay results from the San Javier gold-focused resampling program will be released separately in the coming weeks.

Key Details

• Drilling Progress: 19 holes completed for a total of 20,005 feet, testing near-surface hypogene chalcocite targets and extensions of the silver-rich World's Fair and January-Norton mine structure/vein-hosted systems.
• Mineralization Discovery: Continuous vertical copper mineralization confirmed for over 1,000 metres, combining results from SUN26-001R, SUN26-002R, and historical ASARCO hole TM-8.
• Phase II Completion: Final platform will drill 4-5 additional holes to wrap up Phase II by late June/early July 2026, reaching the required 25,000 ft of drilling.
• Ownership Condition: Completion of the 25,000 ft drilling requirement will increase Barksdale's ownership interest in the Sunnyside deposit to 67.5%.
• Fall 2026 Program: Planned 15,240 metres (50,000 ft) core drill program to extend near-surface copper to depth and define lithologic/structural components. Statements of work are being sent to drill companies, with expected start in late Q3/early Q4 2026.
• Geological Logging: Reverse circulation chip samples show significant sulfides including chalcocite, chalcopyrite, tennantite-enargite, stibnite, sphalerite, and pyrite. At least two holes contain cerargyrite and proustite (silver halide and silver sulfosalt minerals).
• Geophysical Surveys: Proposing an Airborne TEM survey of the entire property to define follow-up targets for CSAMT surveys, designed and implemented by Ellis Geophysical Consulting prior to Fall 2026 drilling.
• San Javier Project: Final assay results received from a gold-focused resampling program; a separate press release detailing results and project impact is expected in the coming weeks.
• Sampling & QA/QC: Samples averaged 5 kg, processed at Skyline Assayers (Tucson, AZ). Gold analyzed via fire assay AAS (30g charge). Multi-element analysis conducted via Aqua Regia digestion with ICP-OES (31 elements). QAQC samples inserted at a 6% ratio (2% standards, 2% blanks, 2% field duplicates). Data reviewed by Qualified Person Alan Roberts, CPG #11260.

Notable Quotes

• William Wulftange, CEO: "The current drill program is focused on exploring and testing near-surface targets to depths of up to 450 metres (1,500 ft). These targets will be further evaluated and defined this fall as part of a 15,240 metre (50,000 ft) drill program... The goal of this program will be to extend the near-surface copper to depth and define the lithologic and structural components within the deposit."
