Barksdale Resources Provides Update On 2026 Reverse Circulation Drill Program And Results At Sunnyside Copper-Gold-Silver Project Barksdale Resources Corp. has provided an update on the 2026 reverse circulation drill program and results along with an integrated exploration update on its flagship Sunnyside copper-gold-silver project in the Patagonia Mountains of Southern Arizona. The Company is currently drilling SUN26-023R and is less than 1,500 feet from completing the 25,000 feet footage requirement to increase ownership of the Sunnyside Project to 67.5%. The Company has received the assay results from an additional 10 holes of its 2026 reverse circulation drilling program at Sunnyside; results are listed in Table 1. Following the strong results from SUN26-001R through SUN26-004R, the Company continued to utilize the pre-planned, United States Forest Service-approved drill sites to test for shallow hypogene copper extensions to the northeast, northwest, east-southeast, and to the southeast of these holes, where drilling is currently underway. Most sites are located approximately 600 to 650 metres laterally from the initial drill pad used for SUN26-001R through SUN26-004R. The newly released results indicate that copper grades decrease to the east, transitioning into a zone of lower copper and higher zinc grades, which may suggest movement away from the high-grade copper-mineralized shell. Holes drilled to the northwest show declining copper grades with increasing silver, lead, zinc, and manganese credits, suggesting this area may reflect higher heat flow. Holes SUN26-017R to SUN26-021R drilled 400m to the southeast of holes 001R to 004R are still awaiting assays. Hole 021R was lost at 810 ft and was redrilled as 022R to the 1,100 ft target depth. Holes SUN26-022R to SUN26-024R are currently being drilled and are located over 600m south/southeast of the initial four high-grade copper intercepts. These holes include one vertical and two angle holes also pointed toward the four high grade intercepts. The Company has engaged VRIFY Technology to refine and identify new mineralized targets on its Arizona properties using AI analysis and expects to release a preliminary target model from that work in early August. Further, Ellis Geophysical Consulting has been retained to review all geophysical surveys in-hand and oversee an airborne ZTEM survey with possible follow-up targeted IP surveys on the Company's Arizona properties. The Company has completed and received assays from 10 step-out holes, SUN26-005R to 014R, 200 m to 650 m away from the first four holes. Assay results from the recent holes define an outward zonation pattern from the high-grade copper of proximal Cu-Ag mineralization, to a transition zone of Cu-(Zn-Ag) mineralization to a distal zone of Mn-Ag-(Zn-Pb) mineralization, mirroring zonation patterns found in Large Copper Porphyry systems throughout the world. The Fall 2026 diamond drill program will focus on extending the high-grade copper mineralization to depth utilizing historical and newly acquired geochemical and geophysical data to optimize drill hole placement and design. Barksdale's 2026 program goals are three-fold. First, to follow-up recommended drill testing of the Bucket Breccia (BB) holes drilled in 1972 by ASARCO that reported high-grade copper results, test targets supported by geochemical and geophysical information, and test for extensions of past producing mine, such as the World's Fair mine and Josephine vein extension. The program drill locations were approved on-site by representatives of the U.S. Forest Service. The second, underlying goal is to complete the 25,000 feet required under the Phase II earn-in agreement with Great Basin Metals, to permanently increase Barksdale's ownership interest in Sunnyside to 67.5%. Once the program is completed, Barksdale will issue 4.9 million common shares in its capital to Great Basin Metals and a cash payment of CAD 550,000. Completion is expected by the end of July. The final stated goal is to begin to gather additional data surrounding the Bucket Breccia drilling that could support a formal National Instrument 43-101 compliant resource estimation. Demonstrating Sunnyside has a stated resource will allow the Company to apply and likely be accepted into the FAST-41 USDA program that helps companies navigate and gain Federal regulatory approvals in an expedited fashion. Modeling work will commence once all drill results are received. Recent Copper and Silver Highlights: 0.3% Cu over 77.7 m from 187.5 m hole depth, including 1.93% Cu over 7.6 m from 187.5 m in SUN26-013R; 0.32% Cu over 12.2 m from 228.6 m hole depth in SUN26-010R; 0.3% Cu over 4.6 m from 620 ft hole depth in SUN26-011R; 2.0 g/t Ag over 182.88 m from 5 m hole depth in SUN26-007R; 4.59 g/t Ag over 91.44 m from a depth of 15.2, including 36.58 m grading 8.77 g/t Ag from a depth of 18.3 m in SUN26-012R; 1.62 g/t Ag and 0.058 g/t Au over 111.25 m from 189 m hole depth in SUN26-009R. A comparison of the Sunnyside porphyry geochemical zonation pattern to the Berkeley porphyry in Montana reveals strikingly similar metal zonation. The Spring 2026 drill program assay results have contributed a great deal of geochemical knowledge to the Company, both in confirming the presence of high-grade copper mineralization continuous to at least 1,000 metres depth but also providing geochemical data that will aid in future drill hole placement. Previously reported high grade copper intercepts in SUN26-001R to 003R were not duplicated in the subsequent holes reported in this news release as had been hoped. Pre-approved drill platforms ~600-650 metres from the initial holes may have overshot the extent of mineralization or there may be an NNW-SSE structural component offsetting the mineral body. Follow-up drilling to the SSW in holes SUN26-021R and 022R should shed light on the lateral continuity question. This remains an early, exploratory phase at Sunnyside with roughly two dozen holes completed. The program's first four holes returned the highest-grade copper before stepping out significantly by 600 to 650 metres. Encountering high-grade copper so early in a system of this scale points to how much of the property is still to be tested. Announcement • Jun 11
Barksdale Resources Corp. Defines Continuous Hypogene Copper Mineralization and Plans Fall 2026 Core Drill Program Barksdale Resources Corp. has completed drilling at the Sunnyside Property with 19 holes totaling 20,005 feet, testing the near surface hypogene chalcocite targets along with extensions of the silver rich World's Fair and January-Norton mine structure and vein-hosted mineral systems. The Phase II drill program is expected to be completed by early July 2026. Copper and silver results from the Company's news release of May 4, 2026, along the A-A" section line, together with historical results from ASARCO hole TM-8, mineralization reported in SUN26-001R and SUN26-002R demonstrates more than 1,000 metres of continuous vertical copper mineralization. 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. The Spring 2026 drill program has focused on retesting mineralized zones previously identified by ASARCO beginning with the historical "BB" drill hole locations where 10 holes were completed (referred to as the Triple C target in the prior press release). The rig then moved to the north 650 metres and drilled to the NE, SE, S and SW, completing four holes to test mineral continuity. The rig was then moved approximately 300 metres to the south where four holes were drilled vertically and to the SW and W, again testing mineral continuity. The final platform is located an additional 400 metres to the southwest where an additional four or five holes will be drilled to complete the Phase II drill program by late June/early July, and complete the required 25,000ft of drilling to increase the Company's ownership interest in the Sunnyside deposit to 67.5%. Logging of the reverse circulation drill chips show all holes contain significant sulfides including chalcocite, chalcopyrite, tennantite-enargite, stibnite, sphalerite and pyrite, and at least two holes contain cerargyrite and proustite (silver halide and silver sulfosalt) minerals. The near-term goal is to define the lateral extents of the copper and polymetallic mineralization to optimize drill locations for the Fall 2026 drill program that will further test the tenor, depth extent and continuity of the copper porphyry system. The Company expects to release further assay results from the Phase II drill program later this month. Barksdale is proposing to complete an Airborne TEM survey of the entire property as a first step to define targets to follow-up with CSAMT surveys; the work is planned to be completed prior to the Fall 2026 drill program. The Company has engaged Ellis Geophysical Consulting to help design and implement the program. The Company has received final assay results from the gold-focused resampling program and will post a separate press release listing the results and impact on the project in the coming weeks. Reverse circulation chip samples are placed in bar-coded samples bags at the drill rig; samples averaging 5 kg are collected from the drill site by Barksdale representatives and transported to a locked, gated compound where they are dried prior to shipping. Dried samples are then placed in large totes and transferred to a Skyline Assayers truck for transport to the assay laboratory in Tucson, Arizona. All samples for this drill program are being submitted for multi-element and gold analysis at Skyline Assayers & Laboratories of Tucson, Arizona. Samples are primary crushed to >75% passing -10 mesh (2000 microns) and then pulverized to >95% passing -150 mesh (100 microns). Gold is then analyzed by fire assay AAS using a 30g charge. Multi-element analysis was conducted using Aqua Regia digestion with ICP-OES analysis for 31 elements. All pulps and coarse rejects will be retained and returned to the Company for long-term storage. Quality Assurance & Quality Control (QAQC) samples were inserted into the sample stream at a 6% overall ratio comprising 2% certified reference materials or standards, 2% blank material, and 2% field duplicates that are collected at the drill. Results from the QAQC program are reviewed by the Qualified Person (QP) for the Company to assure assay result accuracy and precision prior to any data being released to the market.
