Giant Mining Re-Engages ExploreTech for AI-Driven Drill Targeting at Majuba Hill Project

Pershing County, Nevada — February 6, 2026 — Leads & Copy — Giant Mining Corp. has re-engaged Exploration Technologies Inc. to support drill targeting for its 2026 exploration and drilling program at the Majuba Hill Copper-Silver-Gold Project.

Exploration Technologies Inc. (“ExploreTech”), a geoscience technology company located in San Diego, California, specializes in artificial intelligence–driven subsurface modelling.

Recent fieldwork at Majuba Hill has identified multiple high-grade breccia pipes exposed at the surface, enhancing the geological understanding of the project and adding potential tonnage to the geologic model. To date, eight to ten breccia pipes have been identified, with geological indicators suggesting that more may exist across the 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 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 CEO of Giant Mining. “Copper and silver are essential to electrification, infrastructure, defense, and advanced manufacturing, and Nevada remains one of the most mining-friendly and strategically important jurisdictions in the country.

Greenway added that by re-engaging ExploreTech and applying advanced AI-driven subsurface modeling, the company is enhancing its ability to efficiently target mineralization and advance Majuba Hill in a disciplined, responsible manner and that this work supports long-term U.S. economic strength, national security, and the development of a resilient domestic critical-minerals supply chain.

ExploreTech will deploy its 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. 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 centers.

ExploreTech is expected to deliver drill targeting results for the defined area of interest by the end of March 2026.

“Majuba Hill presents a compelling geological system where advanced computational modeling 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 dataset 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.”

ExploreTech’s AI approach is designed to combine surface geology and drilling results with computationally intensive remodelling of existing geophysical datasets to optimize targeting of covered targets. The process generates solutions that cluster on the best fits between the geological and geophysical data and then generates drillhole trajectories designed to cut those clusters most effectively.

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. The Company’s flagship asset is the Majuba Hill Copper, Silver, and Gold District, located 156 miles (251 km) from Reno, Nevada. The property is located 113 road kilometers (70 miles) southwest of Winnemucca, Nevada.

Approximately 89,395 feet of drilling has taken place to date, at a rough replacement value of USD $12.1 Million using current costs.

E.L. “Buster” Hunsaker III, CPG 8137, a non-independent consulting geologist, has reviewed and approved the scientific and technical information contained in this release.

The Company has entered into an extension of its agreement, dated January 23, 2026, with Gold Standard Media, LLC (“GSM”), pursuant to which GSM and its affiliates will continue to provide advertising and investor awareness services to the Company. The extension term is for an additional two (2) months, through August 7, 2026, in consideration of total payments of up to US$450,000.
