GIANT MINING CORP. APPLAUDS U.S. PRESIDENTIAL EXECUTIVE ORDER TO INCREASE DOMESTIC MINERAL PRODUCTION INCLUDING COPPER

Giant Mining Corp., including all stakeholders of its flagship Majuba Hill porphyry copper project in Pershing county, Nevada, applauds U.S. president Donald Trump's executive order dated March 20, 2025, and titled "Immediate Measures to Increase American Mineral Production" seeking to bolster the production of domestic critical minerals, including Copper and Gold, and furthering the country's national security agenda.

The executive order was published on the public registry and the full text of the executive order can be found on the White House's website.

The executive order invokes the use of the Defense Production Act as part of a broad U.S. government effort to expand domestic minerals production on national security grounds. As it relates to project permitting, the order states that it will "identify priority projects that can be immediately approved or for which permits can be immediately issued and take all necessary or appropriate actions ... to expedite and issue the relevant permits or approvals." Furthermore, the order includes provisions to accelerate access to private and public capital for domestic projects, including the creation of a dedicated mineral and mineral production fund for domestic investments under the Development Finance Corp. (DFC).

"We commend the U.S. President for taking decisive action to address the critical need for expanding domestic mineral production, a vital step toward strengthening the nation's supply chain security. This executive order is a significant milestone in revitalizing the domestic mining sector by streamlining the permitting process and providing essential financial support for qualifying projects," said David Greenway, chief executive officer of Giant Mining. "As a U.S.-focused company advancing a copper-silver-gold project in one of the country's premier mining jurisdictions, we are encouraged by the opportunities this policy presents for the future of domestic copper production and the positive impact it may have at the Majuba Hill project."

This latest executive order is in addition to the executive order titled "Addressing the Threat to National Security from Imports of Copper" signed by President Trump on Feb. 25, 2025. The order directs the Department of Commerce, led by Secretary Howard Lutnick, to investigate potential tariffs on copper imports due to national security concerns. The United States currently imports approximately 45 per cent of its copper from major suppliers, including Canada, Mexico, Chile and Peru. Despite domestic reserves in the ground, the United States lags in smelting and refining capacity, with over 50 per cent of global smelting controlled by a single foreign producer.

Majuba Hill's critically important characteristics are as follows.

Location:   Nevada, United States -- a globally top-ranked mining jurisdiction, ranked No. 1 in the Fraser Institute's 2022 Annual Survey of Mining Companies

Project size:  9,684 acres

Infrastructure:   The Majuba Hill property is 113 road kilometres (70 miles) southwest of Winnemucca, Nev., and 251 kilometres (156 miles) northeast of Reno. Access is by well-maintained county roads from the Imlay, Nev., exit on U.S. Interstate 80 and travelling westward 23 miles. People, roads, power and water are the basic elements when considering infrastructure, and Majuba Hill already has a solid infrastructure foundation for building a large facility, which will provide significant savings compared with more remote projects.

History:  historical producer

Drilling:  83,930 feet of drilling to date; rough replacement value of drilling $10.4-million (U.S.) in development costs; 2025 drilling is about to get under way with equipment now on site

Mineralization:  The project shows indications of a potentially large copper-silver-plus-or-minus-gold-mineralized body with many features in common with both large porphyry copper, silver and gold projects.

Expandability:  The induced polarization survey, deep drilling and stepout drilling indicate significant expansion potential, with mineralization open in all directions.

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 is situated in a mining-friendly jurisdiction with supportive regulations and has the potential to become one of the next major copper deposits, critical for meeting the increasing need for this red metal.

We seek Safe Harbor.
