GIANT MINING CORP. MOBILIZATION FOR MARCH 2025 DRILL PROGRAM AT MAJUBA HILL COPPER-SILVER-GOLD PROJECT, NEVADA

Commencing next week, final site preparations and equipment and water delivery will be under way in order to commence drilling at Giant Mining Corp.'s Majuba Hill porphyry copper deposit, a copper, silver and gold project located in Pershing county, Nevada.

Final road drill pad preparations will be completed by Legarza Exploration LLC, with Big Sky Exploration LLC expected to start drilling on or about March 24, 2025, for the previously announced diamond core drilling.

"Gold is nearing an all-time high of $3,000 (U.S.) per ounce and copper has just hit a 2025 high of $4.93 (U.S.) per pound under threat of tariffs and looming copper shortfalls. With drilling now less than two weeks out, we are excited to see final site preparations about to get under way. We look forward to a pivotal moment for Majuba Hill in 2025 following our best results to date in 2024," said David Greenway, chief executive officer of Giant Mining. "The company is fully funded for an active year of exploration and development drilling to add to over 100 drill holes and over 80,000 feet of past drilling in order to work towards a [National Instrument] 43-101 mineral resource estimate for the project."

As previously announced, the company plans to drill four holes totalling 4,400 feet (1,340 metres) of core drilling within the existing exploration target area. A minimum of 2,600 feet will be completed and the contract does not have a maximum drilling requirement, allowing for flexibility in the execution of the project. If the holes are in mineralization beyond the contemplated 1,100 feet (335 metres) per hole, the company has allowed for drilling to continue up to 1,600 feet (487 metres).

Blue Sky will be using the LF90D surface diamond coring drill, which features a telescopic dump mast, making it ideal for truck or crawler mounting to suit site conditions. The modular layout of components on the drill makes it easy to replace worn components in the field, minimizing downtime and enabling more flexible usage. The LF90D has a total depth capacity of up to 3,915 feet (1,193 metres) (NRQ W-Wall).

The core program is designed to follow up geology and mineralization intersected in core holes MHB-30 and MHB-31.

This maiden 2025 drill program is a key component of Giant Mining's continuing initiative to advance exploration efforts at Majuba Hill. The planned drill program will target the Southern Breccia corridor, with holes oriented to intersect the high-grade mineralized breccia. Drilling will focus on the deeper portions of the breccia and the extensions of the high-grade copper zones below the historic underground workings.

Some of Majuba Hill's critically important characteristics are as follows.

Location:  Nevada -- the No. 1 mining jurisdiction on the planet according to the Fraser Institute

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 IP survey, deep drilling and stepout drilling indicate significant expansion potential, with mineralization open in all directions.

Fully financed:  secured financing for 2025 drilling campaign

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.
