COPPER ONE COMMENCES INITIAL EXPLORETECH AI-DESIGNED DRILL HOLE AT MAJUBA HILL AS PART OF 2026 10,000-FOOT PROGRAM

Copper One Resources Corp. has commenced drilling of the initial diamond drill core hole designed by Exploration Technologies Inc. at its flagship Majuba Hill copper-silver-gold project located in Pershing county, Nevada.

The hole represents the first ExploreTech artificial-intelligence-designed target to be drilled as part of Copper One's 2026 10,000-foot drill program at Majuba Hill. The company previously worked with ExploreTech during an earlier exploration program at Majuba Hill and continues to collaborate with the geoscience technology company, based in San Diego, Calif., which specializes in artificial-intelligence-driven subsurface modelling, to support drill targeting and geological interpretation in 2026.

"Majuba Hill has entered an important new phase with drilling now under way on our initial ExploreTech AI-designed core hole," said David Greenway, president and chief executive officer of Copper One. "As artificial intelligence accelerates the buildout of data centres, electrification infrastructure and next-generation power systems, the need for secure domestic copper supply continues to grow. At Majuba Hill, we are applying advanced AI-driven exploration tools to help refine targeting, improve geological confidence and guide a disciplined drill program focused on expanding known mineralization. Our objective is to continue advancing this large Nevada copper-silver-gold system toward a future maiden mineral resource estimate and unlocking its potential as a North American copper exploration asset."

Drilling has commenced on the company's initial ExploreTech AI-designed diamond drill core hole at Majuba Hill. The hole is designed to extend approximately 2,500 feet (762 metres) and is intended to test AI driven modelling of geophysics and follow up on historic drill holes that intersected significant copper-silver-gold mineralization. The hole was designed using ExploreTech's AI-driven modelling platform in combination with Copper One's extensive Majuba Hill technical database, including historical drilling, geophysics, geology, alteration data, surface mapping and previous exploration results.

The continued engagement with ExploreTech is supporting a disciplined, data-driven drill program under way to expand known mineralization at Majuba Hill, improve the company's understanding of the broader mineralized system and support the company's longer-term objective of evaluating the potential for a future maiden mineral resource estimate at Majuba Hill.

Drilling under way at Majuba Hill

The company has commenced drilling of the initial ExploreTech AI-designed hole under the 2026 drill program following technical planning, drill hole design, operational readiness, contractor co-ordination and review of priority target areas. The hole is expected to provide important technical information to assist in validating the company's geological model and evaluating priority subsurface targets.

The 2026 drill program is designed with a focus on:

• Testing priority AI-generated subsurface targets;
• Expanding known copper, silver and gold mineralization;
• Improving geological continuity within the Majuba Hill system;
• Evaluating areas with potential for stepout mineralization;
• Advancing the technical foundation required to work toward a future maiden mineral resource estimate.

The company cautions that additional exploration, drilling, technical studies and analysis will be required before any mineral resource estimate can be completed. There is no certainty that future exploration will result in the definition of mineral resources at Majuba Hill.

Continued AI-driven support for drilling at Majuba Hill

Majuba Hill benefits from a substantial technical database generated through multiple phases of historical and recent exploration. This database includes drilling, geophysical surveys, geological mapping, alteration studies and target generation work that support the company's continuing evaluation of Majuba Hill as a copper-silver-gold exploration project.

ExploreTech is working with Copper One's technical team to further evaluate this database through advanced computational modelling and AI-assisted scenario generation. The objective of this work is to refine drill targeting, evaluate priority subsurface opportunities, and support the design and execution of drill holes that may test extensions of known mineralization and potential new mineralized zones within the broader Majuba Hill system.

The company believes that combining Majuba Hill's extensive exploration data set with ExploreTech's AI-driven targeting platform provides a data-driven framework to support the now-commenced 2026 drill program. The continued engagement is intended to help Copper One prioritize high-impact targets, improve exploration efficiency and focus drilling on areas with the strongest potential to expand known mineralization.

"We are very excited to be continuing our collaboration with Copper One through this drill campaign and look forward to the results," said Tyler Hall, president of ExploreTech. "Majuba Hill is ideally suited to our technology, and it continues to be a pleasure working with the Copper One team."

Building toward a future maiden mineral resource estimate

Copper One's longer-term objective at Majuba Hill is to advance the project through systematic exploration, disciplined drilling and modern geological modelling toward the potential establishment of a maiden mineral resource estimate. The company believes that the continued application of AI-assisted drill design, combined with the project's extensive historical database, may assist in identifying additional areas of mineralization and improving confidence in the overall geological model.

Majuba Hill has been the subject of significant historical exploration and drilling, and the company believes the project remains open for potential expansion. The now-commenced 2026 drill program is expected to represent an important step in advancing the project from exploration targeting toward a more resource-focused development pathway.

"ExploreTech's platform allows us to better utilize the depth of technical information already available at Majuba Hill," added Mr. Greenway. "Rather than simply drilling on historical assumptions, we are using AI-assisted modelling to help refine where drilling can have the greatest potential impact. We believe this approach can help Copper One make more informed exploration decisions as we advance the now-commenced drill program and work to expand the known mineralized footprint."

About the Majuba Hill copper-silver-gold deposit, Nevada

Majuba Hill is Copper One's flagship copper, silver and gold exploration project, located in Nevada, United States, one of the world's premier mining jurisdictions. Nevada was ranked the No. 1 mining jurisdiction globally in the Fraser Institute's 2022 annual survey of mining companies, underscoring the strategic importance of Majuba Hill's location in a stable, mining-friendly region with a long history of responsible mineral development.

The Majuba Hill property covers approximately 9,684 acres and is located about 113 road kilometres, or 70 miles, southwest of Winnemucca, Nev., and 251 kilometres, or 156 miles, northeast of Reno. The project is accessible by well-maintained county roads from the Imlay, Nev., exit on U.S. Interstate 80, followed by an approximately 23-mile drive west. Access to people, roads, power and water is fundamental considerations for advancing mineral projects, and Majuba Hill benefits from a strong infrastructure foundation in each of these areas. This represents a meaningful potential advantage compared with more remote projects, where infrastructure can be a major cost and development hurdle.

Majuba Hill is a historical producer with a substantial exploration database, including approximately 89,395 feet of drilling completed to date, which provides Copper One with a significant technical foundation for continuing exploration.

Exploration work at Majuba Hill has identified indications of a potentially significant copper, silver and gold mineralized system. However, further drilling, geological modelling and technical evaluation will be required to determine the extent, continuity and significance of mineralization at the project. Majuba Hill is located in Nevada, a leading mining jurisdiction, and benefits from scale, access, infrastructure and a substantial historical exploration database.
