GIANT MINING RECEIVES RESPEC REPORT VALIDATING TECHNICAL BREAKTHROUGH AND DRILL PROGRAM ADVANCEMENT FOR MAJUBA HILL COPPER PROJECT, NEVADA

Giant Mining Corp. has received an independent recommendations report prepared by Respec Company LLC for the company's flagship Majuba Hill copper-silver-gold project in Pershing county, Nevada.

The report reviews the updated geological framework and provides a disciplined exploration road map that the company believes represents an important step in evaluating Majuba Hill's longer-term potential as a domestic U.S. copper and silver asset.

This report, in combination with the company's technical team, will guide the company's up-to-10,000-foot-drill program, as announced company's news release dated Jan. 30, 2026.

"The independent Respec report represents a transformational technical milestone for Giant Mining and significantly advances our understanding of the opportunity at Majuba Hill," said David Greenway, president and chief executive officer of Giant Mining. "With a refined geological model, secured funding and a clearly defined drill strategy, we are now positioned to aggressively pursue discovery-driven exploration across this highly prospective system. The identification of key geological controls substantially enhances our ability to target high-priority zones with precision and confidence. Majuba Hill is emerging as a compelling U.S.-based copper-silver exploration opportunity at a time when domestic critical mineral security has never been more important. Nevada is the top-ranked mining jurisdiction in the United States, and we believe Majuba Hill has the scale, infrastructure and geological foundation to support meaningful exploration success. Our team is energized and fully focused on executing our upcoming drill program and unlocking the broader potential of Majuba Hill as we work to create substantial long-term value for our shareholders, subject to continued exploration success."

Respec recommendations

The Respec report recommends that the company focus on discovery-driven exploration. Respec identifies recognition of the tourmaline breccia pipe-hosted copper system as a significant technical advancement that materially improves the company's ability to target higher-grade mineralization and assess future development possibilities.

Copper is a critical mineral fundamental to electrification, infrastructure, defence applications and data-centre growth within the United States. With long-term demand projected to outpace supply, the company views Majuba Hill's location in Nevada, a top-ranked mining jurisdiction, as strategically relevant to America's future domestic copper and silver requirements, subject to continued exploration success.

The completion of the Respec technical recommendations represents an important milestone in Giant Mining's systematic advancement of Majuba Hill. With a refined geological model, secured exploration financing, and a coming drill program of up to 10,000 feet, the company is positioned to execute the next phase of disciplined, data-driven exploration. Management believes these developments strengthen the technical foundation of the project and enhance its strategic relevance within the U.S. critical minerals landscape, subject to continued exploration success.

Key findings and strategic implications

The Respec report highlights several factors that underpin the project's longer-term potential while reinforcing the need for continued exploration:

• Identification of tourmaline breccia pipes as a key control of copper mineralization, providing a refined exploration model;
• Recognition that high-grade copper and silver mineralization may occur in discrete breccia zones that require careful geological targeting;
• Recommendation to re-evaluate historical drilling, surface data and geophysics within the context of the new deposit model prior to systematic drilling;
• Acknowledgment that future development scenarios are contingent on discovering additional high-grade breccia bodies and defining their spatial distribution;
• Confirmation that Nevada's mining jurisdiction, infrastructure and regulatory environment are supportive of potential future development if exploration is successful.

Respec outlines conceptual scenarios under which continued exploration success could ultimately support either bulk-tonnage open-pit or smaller-scale underground mining approaches. These scenarios are presented as exploration targets, not mineral resources or economic assessments, and remain subject to significant geological risk.

Alignment with U.S. domestic supply objectives

While Majuba Hill remains at an exploration stage, the company believes that advancing a disciplined, science-driven, staged exploration program is the necessary first step in determining whether the project could, over time, contribute to domestic U.S. copper and silver supply. The Respec recommendations provide a technically sound framework for advancing the project responsibly while maintaining alignment with broader U.S. critical mineral priorities.

Majuba Hill's critically important characteristics are as follows.

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.

With a strengthened technical framework, supportive jurisdiction and financed exploration program, Giant Mining is focused on advancing Majuba Hill through systematic drilling and technical evaluation. The company remains committed to responsible exploration, technical transparency and creating long-term shareholder value through discovery-focused exploration.
