The secured P note will mature 18 months from the date of issuance and will bear interest at a rate of 6 per cent per annum, payable on the maturity date.

As security for the secured P note, Sovereon has agreed to grant Giant Mining a security interest in the subject shares pursuant to a share pledge agreement dated March 6, 2026. Under this agreement, the subject shares will be pledged, mortgaged, charged and assigned in favour of Giant Mining until repayment obligations are fully satisfied.

David C. Greenway, president and chief executive officer of Giant Mining, commented: "This transaction represents a strategic monetization of a non-core asset while maintaining downside protection through a secured structure. The proceeds strengthen our financial position and allow us to remain focused on advancing our flagship Majuba Hill project, where we see significant potential to deliver long-term value for our shareholders."

Premium Exploration (USA) Inc. asset overview

Premium Exploration (USA) holds a 100-per-cent interest in the Friday gold project, located in the historic Orogrande mining district in Idaho, United States, approximately 16 kilometres south-southwest of Elk City. The project hosts a significant historical National Instrument 43-101 mineral resource estimate of approximately 1.24 million ounces of gold in indicated and inferred categories, based on prior drilling and technical studies. The property benefits from extensive historical exploration, including over 85,000 feet of drilling, and remains open for expansion in multiple directions, highlighting strong potential for further resource growth. Metallurgical testing has demonstrated favourable gold recoveries, and the project is situated within a well-established, mining-friendly jurisdiction with a long history of gold production.

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.

We seek Safe Harbor.
