BARKSDALE BEGINS PHASE II EARN-IN DRILL PROGRAM AT SUNNYSIDE

Alford Drilling has arrived at Barksdale Resources Corp.'s Sunnyside property in Arizona and the phase II earn-in drill program is under way.

The phase II drill program will test near-surface chalcocite (copper) occurrences targets in the central portion of the project identified and drilled by Asarco in the 1990s; copper, gold and polymetallic anomalies near the Sunnyside and Volcano mines born out of a fracture sampling study by Big Rock Exploration in 2019; and geophysical resistivity/chargeability targets south of the World's Fair mine generated by NSAMT (natural-source audio-frequency magnetotelluric) surveys performed by Geofisica TCM in 2018. The program is expected to take three to four months to complete. Barksdale anticipates assaying to take up to two months to receive, following submission to the laboratory.

"We are thrilled to begin the phase II drilling at Sunnyside," said Barksdale chief executive officer William Wulftange. "The financial support of our long-term as well as new shareholders, planning by our technical staff, guidance of the USFS [U.S. Forest Service], the USFWS [U.S. Fish and Wildlife Service], and long-term relationships with talented environmental and drilling contractors have enabled our story to march forward."

Harshaw district update

Barksdale's neighbour, South32 Ltd., recently provided development results of its Hermosa project. South32 released copper equivalent assay results from recent drilling at the Peake deposit and stated that the Peake deposit may be part of the Taylor deposit and the two may eventually be shown to be the same deposit. It is designing a small, add-on production circuit to recover the copper endowment. Recent Barksdale drill results and historical Asarco data have shown that Taylor deposit continues into Sunnyside in holes SUN24-002B and TCH-2A, and now South32 reports Peake may combine with Taylor (source: South32 presentation, Feb. 13, 2026).

It is Barksdale's operating premise that the emplacement of the Sunnyside porphyry system generated proximal copper porphyry-style deposits, polymetallic skarn deposits, proximal to distal polymetallic carbonate replacement deposits, near-surface copper-gold, silver-lead and other metal deposits mined since the 1850s and deposits yet to be discovered. Barksdale is focused on exploration, discovery and expanding the known metal endowment with every sample taken and drill hole completed.

San Javier

Barksdale is reviewing a sample collection program to assay historic core drill samples and core from 2021 Barksdale drilling for gold content. San Javier is classified as an iron oxide copper-gold deposit and Barksdale's drill campaign in 2021 identified at least three broad intercepts of gold values, including 27 metres (93 m to 102 m) of 1.97 grams per tonne gold in SJ21-04, along with two, 21-metre intervals in SL21-05 of 0.55 g/t (42 m to 63 m) gold followed by 1.57 g/t (114 m to 125 m) in hole SJ21-05.

Additional information

Barksdale Resources operates under a plan of operation, project No. 2810-030503-POO-2018-004, approved by the U.S. Forest Service in September, 2023. Barksdale Resources and the USFS meet when needed to review proposed work and subsequent reclamation of disturbed ground. The most recent site review regarding the company's phase II drill program occurred in January, 2026.

The BRE fracture study in 2019 collected select rock scrapings along outcrop fracture surfaces in the central and northern parts of the Sunnyside project. These results were then plotted on a plan view map and contoured using BRE contouring programs to highlight high and low metal concentrations. Elements contoured include copper, gold, silver, zinc, lead, antimony and manganese.

The phase II earn-in requirements, as outlined in the joint venture agreement with Great Basin Metals (GBM), require the company to drill 25,000 feet and spend $6-million, pay $550,000, and issue 4.9 million shares to increase the company's 51-per-cent ownership of Sunnyside to 67.5 per cent.

The joint venture agreement allows for excess expenditures from the phase I earn-in program to be applied to phase II spend requirements. As such, the required phase II expenditures were previously met in the phase I program. Following completion of the phase II drill program and subsequent cash and share payments, all future expenditures will be jointly financed by Barksdale Resources and GBM at the ratio of 67.5 per cent to 32.5 per cent.
