GIANT MINING RE-ENGAGES EXPLORETECH FOR AI-DRIVEN 2026 DRILL TARGETING AT MAJUBA HILL COPPER-SILVER-GOLD PROJECT IN NEVADA

Giant Mining Corp. has re-engaged Exploration Technologies Inc., a geoscience technology company located in San Diego, Calif., specializing in artificial intelligence-driven subsurface modelling, to support drill targeting for the company's planned 2026 exploration and drilling program at its flagship Majuba Hill copper-silver-gold project in Pershing county, Nevada.

Advancing the geological model at Majuba Hill

Recent fieldwork completed at Majuba Hill has identified multiple high-grade breccia pipes exposed at surface, materially enhancing the company's geological understanding of the project and adding significant potential tonnage to the evolving geologic model. To date, eight to 10 breccia pipes have been identified, with geological indicators suggesting that many more breccia pipes may exist across the broader property.

These breccia pipes are interpreted to be genetically linked to deep, concealed intrusive bodies, which are believed to play a key role in driving mineralization. The identification and accurate modelling of these hidden intrusions is expected to significantly improve drill targeting and exploration efficiency.

"Advancing Majuba Hill aligns directly with the United States' growing focus on securing reliable domestic sources of critical and strategic minerals," said David Greenway, president and chief executive officer of Giant Mining. "Copper and silver are essential to electrification, infrastructure, defence and advanced manufacturing, and Nevada remains one of the most mining-friendly and strategically important jurisdictions in the country. By re-engaging ExploreTech and applying advanced AI-driven subsurface modelling, we are enhancing our ability to efficiently target mineralization and advance Majuba Hill in a disciplined, responsible manner. We believe this work supports long-term U.S. economic strength, national security and the development of a resilient domestic critical-minerals supply chain."

"Majuba Hill presents a compelling geological system where advanced computational modelling can materially improve drill targeting, especially following our success at Majuba Hill last year," said Dr. Tyler Hall, president of ExploreTech. "By integrating Giant Mining's extensive historical data set with our Engine AI platform, we can evaluate thousands of possible subsurface scenarios to identify the most probable locations of concealed intrusive sources associated with breccia pipe development. This approach allows for more informed, efficient drilling decisions and has the potential to significantly enhance exploration success at Majuba Hill."

Artificial-intelligence-driven targeting using Engine AI

Under the renewed engagement, and building on last year's successful results, ExploreTech will deploy its proprietary Engine AI and cloud-based computing platform in collaboration with Giant Mining's technical team to model the most probable locations of buried intrusive sources associated with breccia pipe development.

ExploreTech's approach will include the generation of thousands of potential subsurface geological models, allowing the company to statistically evaluate the most likely locations of high-grade breccia pipes that may be concealed beneath postmineral cover.

Key elements of the work program include:

• Refinement of the study area to focus on priority areas of interest identified by Giant Mining;
• Simulation of multiple potential intrusive source scenarios at depth;
• Integration and analysis of Majuba Hill's extensive historical exploration database;
• Targeting informed by resistivity data, which may highlight zones of potassic alteration and disseminated mineralization consistent with intrusive centres.

Positioning for 2026 drilling

ExploreTech is expected to deliver drill targeting results for the defined area of interest by the end of March, 2026, providing Giant Mining with advanced technical inputs to support planning and execution of its upcoming drill program.

The company believes that combining modern AI-driven subsurface modelling with Majuba Hill's extensive historical data set represents a powerful approach to unlocking additional value at the project.

About Giant Mining Corp.

Giant Mining is focused on identifying, acquiring, and advancing late-stage copper and copper/silver/gold projects to meet the growing global demand for critical metals. This demand is driven by initiatives like the Green New Deal in the United States and similar climate-focused programs worldwide, which require substantial amounts of copper, silver and gold for electric vehicles, renewable energy infrastructure, and the modernization of clean and affordable energy systems.

The company's flagship asset is the Majuba Hill copper, silver and gold district, located 156 miles (251 kilometres) from Reno, Nev. Majuba Hill benefits from a mining-friendly regulatory environment and strong local infrastructure. While still an exploration-stage asset, the geological footprint and scale of mineralization indicate that further work is clearly justified and that the system may host significant copper potential.

We seek Safe Harbor.
