GIANT MINING CORP. COMMENTS ON U.S. SECTION 232 PROCLAMATION STRENGTHENING DOMESTIC COPPER AND CRITICAL MINERAL SUPPLY CHAINS

Giant Mining Corp. has welcomed United States Presidential Proclamation 11001, issued on Jan. 14, 2026, under Section 232 of the Trade Expansion Act of 1962, titled Adjusting Imports of Processed Critical Minerals and Their Derivative Products into the United States. The proclamation seeks to strengthen secure, reliable and allied supply chains for processed critical minerals and their derivative products entering the United States.

"Copper has become a foundational material for the U.S. defence industrial base -- it is essential to national security, military readiness, electrification, advanced weapons systems, AI infrastructure and America's long-term economic strength," said David Greenway, chief executive officer of Giant Mining. "The U.S. government's Section 232 proclamation reinforces the strategic imperative to secure reliable, American-sourced copper supply chains that reduce foreign dependence and support the Pentagon's growing demand for critical minerals. With Majuba Hill located in a premier U.S. mining jurisdiction, we believe the project is well positioned to contribute to domestic manufacturing resilience, defence readiness and the rebuilding of America's critical mineral supply base."

Proclamation 11001 follows a comprehensive Section 232 investigation that found the United States to be significantly dependent on foreign sources for many critical minerals essential to national security, energy transition technologies and advanced manufacturing. The proclamation calls for enhanced engagement with allied partners and outlines potential measures to strengthen domestic and allied critical mineral supply chains.

Relevance to copper and electrification

Copper is a cornerstone metal underpinning United States electrification, grid expansion, electric vehicles, renewable energy infrastructure, and advanced data centre and defence applications. As the U.S. accelerates investments in AI infrastructure, clean energy and domestic manufacturing, secure access to copper supply from stable jurisdictions has become increasingly strategic.

Giant Mining's Majuba Hill copper-silver-gold deposit, located in Nevada, sits within one of the world's most established mining jurisdictions and directly aligns with the objectives outlined in the proclamation. Nevada hosts existing mining infrastructure, skilled labour and regulatory frameworks that support responsible domestic mineral development.

Strategic implications for Majuba Hill

The company believes the Section 232 proclamation reinforces several favorable long-term fundamentals for Majuba Hill, including:

• Formal recognition of copper as a strategic metal critical to U.S. infrastructure modernization, grid hardening, electrification, advanced manufacturing and defence readiness, reflecting copper's growing role in military systems, AI-enabled technologies and national security applications.
• Heightened U.S. government emphasis on domestic and allied sourcing, reinforcing policy momentum toward reducing foreign dependence on critical minerals and strengthening supply chain sovereignty. This policy environment may support enhanced investment interest, greater permitting certainty and potential strategic partnerships for U.S.-based copper development projects.
• Support for downstream processing capacity and end-to-end supply-chain resilience, underscoring the importance of developing not only mineral resources, but fully integrated North American copper supply solutions capable of supporting U.S. manufacturing, infrastructure deployment and the defence-industrial base.

Majuba Hill is an advanced copper-silver-gold system with a history of exploration and mining, located near existing infrastructure in Nevada. The project's geological setting, scale potential and proximity to U.S. end markets position it as a compelling asset as domestic copper demand continues to accelerate.

Majuba Hill's critically important characteristics are as shown herein.

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.
