Barksdale Resources Releases Final Spring 2026 Program Results and Plans 8,000-Metre Fall 2026 Diamond Drill Program And ZTEM Survey

Barksdale Resources Corp. (BRO) has released the final results of its Spring 2026 reverse-circulation (RC) drilling programme at the Sunnyside property in the Patagonia district, Arizona. The completed campaign consisted of 24 holes totaling 7,862 metres, with all assays received. The company also outlined a proposed Fall 2026 programme and addressed several administrative updates.

Key intercepts reported in the release include:

• SUN26-018R (new): 102.1 m of 0.19% Cu from 93.0 m, including 18.3 m of 0.35% Cu from 111.3 m
• SUN26-021R (new): 21.3 m of 0.20% Cu from 205.7 m; and 6.1 m of 0.35% Cu from 256.0 m
• SUN26-013R (released July 20/27): 109.7 m of 0.32% Cu from 158.8 m; 7.6 m of 1.93% Cu from 187.4 m; 64.01 m of 0.47% Cu from 188.98 m
• SUN26-001R (released May 4): 39.62 m of 0.95% Cu from 248.41 m
• SUN26-002R (released May 4): 60.9 m of 0.90% Cu and 60.9 m of 0.93% Cu from 265.12 m
• SUN26-003R (released May 4): 53.34 m of 0.64% Cu from 7.62 m

Beyond the assay data, Barksdale proposed an airborne ZTEM survey across the Sunnyside and Four Metals properties. The company also described a phased diamond drilling programme totalling 16,000 metres, with an initial phase of 8,000 metres currently proposed to its joint venture partner and not yet approved.

Administrative corrections were issued regarding the August 31, 2026 release, clarifying that the joint venture management committee consists of two Barksdale delegates and two Great Basin delegates, rather than the previously stated three and two. Additionally, the company announced a grant of 1,500,000 options and 1,000,000 share units.

Barksdale Resources Corp. (BRO) is a pre-resource explorer with no mineral resource at its Sunnyside project, while its San Javier project holds an NI 43-101 Preliminary Economic Assessment. The company’s thesis rests on scale, grade, and the potential to eventually define a resource.

Only two drill holes, SUN26-018R and SUN26-021R, contain assays not previously seen by the market. All other holes highlighted in the release—013R, 001R, 002R, and 003R—were published in May and July. The new holes report the weakest copper results in the release’s highlights: 0.19% and 0.20% Cu, which fall below the deposit-type band and around or under porphyry cut-off.

The Fall 2026 drilling plan represents a continuation of previous announcements. On June 11, the company announced 15,240 m; on July 20, it announced 15,420 m; and this release announces a phased 16,000 m program with an initial 8,000 m, now subject to joint venture approval. The ZTEM survey has been trailed since June and July.

The anchor result for the market is the May 4, 2026 discovery release, which reported SUN26-002R at 0.45% Cu over 392.19 m, including two intervals of approximately 61 m at 0.90% and 0.93% Cu. That release moved the stock from C$0.21 on May 1 to C$0.33 on May 4, peaking at C$0.53 by May 20-25, a 6x increase from the January base of C$0.09.

The stock has since round-tripped from C$0.53 to C$0.13-0.14 by August 20, 2026, and sits at C$0.23 on the release date, only about 10% above its pre-discovery close of C$0.21. The market has marked the stock down on each successive low-grade batch: June 11 at C$0.34, July 20 at C$0.21, July 27 at C$0.19, and August 31 at C$0.17. The new best hole carries roughly 11% of the anchor's copper-metres at 42% of its grade.

The stock rallied roughly 77% from C$0.13 on August 20 to C$0.23 on September 18 into this print. The high-grade "lode vein" narrative that drove the May spike is not being replicated in step-outs; the deposit is reading as a large, sub-cut-off grade porphyry halo with narrow high-grade structures. At a pre-resource explorer, extension of the mineralized footprint is normally material, but here it is not, because the extension carries no economic grade and the footprint claim was already made in June ("over 1,000 m depth") and July (">600 m strike").

Barksdale Resources Corp. (TSXV: BRO, OTCQB: BRKCF, FSE: 2NZ) is a Vancouver-headquartered, pre-revenue base-metal explorer. For the fiscal year ending March 31, 2026, the company reported nil revenue, a net loss of C$2.72 million, and accumulated losses of C$38.24 million, accompanied by an explicit going-concern flag. The MD&A cites FY2026 exploration and evaluation expenditure of C$3.52 million, primarily directed at the Sunnyside and San Javier projects.

The Sunnyside project, located in the Patagonia district of Arizona, serves as the company’s flagship asset, comprising 286 unpatented claims over 5,223 acres. It borders South32’s Hermosa project on three sides. Ownership increased from 51% to 67.5% following the completion of a Phase II earn-in from Great Basin Metals in August 2026, which involved US$550,000 in cash and 4.9 million shares. The project currently holds no mineral resource, reserves, economic study, or metallurgical data. Historical, pre-NI 43-101 intercepts referenced in presentations—specifically 17 m of 17% Zn+Pb with 337 g/t Ag and 1.3% Cu, and 38 m of 15% Zn+Pb with 229 g/t Ag—are unverified.

The San Javier project in Sonora, Mexico, consists of 12 concessions covering approximately 1,184 hectares. Barksdale holds 100% ownership following the final Tusk payment of C$227,500 in cash plus 4.55 million shares in July 2026. The property is characterized as an IOCG-style Cu-Au deposit. A NI 43-101 Preliminary Economic Assessment (PEA) by Tetra Tech, dated January 2, 2024, identified measured and indicated resources of 70.1 Mt containing 419 million pounds of copper, of which 289.4 million pounds are recoverable by heap leach. The PEA reported a 26.3% pre-tax IRR, a 3.8-year payback period, and recoveries of 85%/75%/60% for leach cap-oxide/mixed/sulphide categories, with cut-offs of 0.04%/0.07%/0.08% Cu. While gold was present, it was excluded from the PEA; however, re-assaying of 2007 core rejects, including 9 m at 3.464 g/t Au and 12 m at 1.084 g/t Au, is underway to assess a potential gold addition. Discrepancies exist between the presentation and the MD&A regarding pre-tax NPV figures at a 7% discount rate, cited as C$111.9M versus C$118.8M.

Other early-stage Arizona assets include Canelo (433 claims), Goat Canyon (314 claims), San Antonio (315 claims, with Teck retaining a 1.5% NSR and first right of refusal), and Four Metals (40 claims). The FY2026 MD&A discloses a C$342,685 impairment on Four Metals, San Antonio, and Canelo/Goat Canyon due to no planned future expenditure.

According to the company’s September 1, 2026 presentation, the capital structure includes 234,867,510 shares outstanding, 11,790,655 options, and 95,217,797 warrants, resulting in a fully diluted count of 341,875,962. Convertible debt of approximately C$4.5 million matures on December 31, 2028, with a conversion price of C$0.10-C$0.12. Notable holders include Medalist Capital (14%), Crescat Capital (13%), Delbrook (6%), board and management (4%), Osisko Development (3%), and Teck (3%).
