GIANT MINING CORP. JOINS NEVADA MINING ASSOCIATION TO SUPPORT U.S. EXECUTIVE ORDER BOOSTING DOMESTIC MINERAL PRODUCTION

Giant Mining Corp. has joined the Nevada Mining Association (NVMA), widely recognized as one of the top 10 mining organizations worldwide. This membership reflects the company's continuing commitment to responsible mineral development in Nevada and supports its efforts to advance domestic resource production in the United States.

It also aligns with the recent executive order signed by President Donald J. Trump on March 20, 2025, directing immediate measures to increase american mineral production. The company's flagship Majuba Hill copper-silver-gold project, located in Pershing county, Nevada, stands to benefit from these national strategic priorities.

The company believes that membership in the Nevada Mining Association provides valuable access to industry insights, legislative developments and strategic networking opportunities -- tools that reinforce Giant Mining's commitment to operational excellence and environmental stewardship. This affiliation further underscores the company's dedication to responsible mining practices, sustainable growth, and meaningful contributions to Nevada's mining communities and the broader resource sector.

"Joining the Nevada Mining Association is an exciting step forward for Giant Mining Corp. It not only reinforces our commitment to responsible and sustainable mining but also connects us with a respected network of industry leaders who are shaping the future of mining in Nevada," said Giant Mining chief executive officer David Greenway. "As we continue to advance the Majuba Hill copper-silver-gold deposit, being part of this association will ensure we stay engaged with evolving regulatory standards and community priorities -- both of which are essential to our long-term success."

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

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.
