GIANT MINING CORP. APPOINTS JOHN PERCIVAL AS NON-EXECUTIVE CHAIRMAN

Giant Mining Corp. has appointed John Percival as non-executive chairman of the board of directors.

Mr. Percival brings more than five decades of global capital markets experience, with an extensive history of raising over $1-billion for public companies. He has a deep and influential presence in Australian financial markets, one of the largest and most active global capital hubs for mining investment, with over $12-billion to $15-billion typically raised annually across the mining and exploration sector. During 2024 and 2025, Australian mining markets experienced significant inflows driven by copper, uranium, critical metals and gold, making Australia the most active global jurisdiction for junior and mid-tier mining financing.

His leadership position within these markets is expected to significantly enhance Giant Mining's visibility and investor reach.

David Greenway, chief executive officer of Giant Mining, stated: "John's reputation, experience and global network, particularly in Australia and Southeast Asia, make him an invaluable addition to our leadership team. His ability to catalyze capital markets visibility and support high-growth mining ventures aligns perfectly with our strategy as we continue advancing the Majuba Hill project. We are honoured to welcome John as our non-executive chairman."

Majuba Hill is a standout copper asset with growing recognition, and I see a tremendous opportunity to elevate the company's profile across Australia and Southeast Asia. I look forward to supporting David and the team as we expand our capital markets reach, strengthen global investor engagement and advance Majuba toward its next major milestones."

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.
