Barksdale Meets Technical Milestones for

Phase II Earn-In and Updates SUN26-013R

Assay Result of 65.5 Metres of 0.47% Cu and

1.24 g/t Ag, Including 7.6 Metres of 1.93% Cu

and 1.96 g/t Ag

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.

Table 1. Updated assay results with additional (>10,000 ppm) overlimit values included.

Alan Roberts, Barksdale's Vice President of Explorations, says, "The results from the drill hole SUN26-

013R are consistent with those that were observed in holes SUN26-001R, -002R and -003R (Press

release dated May 04, 2026). 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.

Sampling and QAQC

Reverse circulation chip samples are placed in bar coded samples bags at the drill rig; samples

averaging 5kgs 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.

Scientific and technical information in this news release has been reviewed and approved by Alan

Roberts, Vice President of Exploration of the Company, a Certified Professional Geologist (CPG) with

the American Institute of Professional Geologist (AIPG # 11260) and is a "Qualified Person" as defined
