GIANT MINING PLANS UP TO 10,000-FOOT MULTI-PHASE DRILL PROGRAM AT MAJUBA HILL COPPER-SILVER PROJECT, NEVADA

Giant Mining Corp. is planning up to 10,000 feet (3,048 metres) of drilling in a multiphased drill program and exploration program at the company's 9,684-acre flagship Majuba Hill copper-silver-gold project in Pershing county, Nevada.

The multiphased drilling and exploration program is anticipated to include:

• Phase 1 -- up to 5,000-foot (1,524-metre) core drill program;
• Underground mapping and sampling;
• Additional surface sampling for additional follow-up drill targeting;
• Phase 2 -- up to 5,000-foot (1,524-metre) core drill program.

The multiphased drilling and exploration program will be guided by over 100 previous drill holes across more than 89,000 feet of drilling and will include input from Respec Engineering. Recent reviews of the 2024 to 2025 exploration results, including all drilling, surface geologic mapping and surface geochemical sampling his identified numerous mineralized breccia bodies (see news release dated Jan. 16, 2024). Intercepts in multiple drill holes returned high-grade copper and silver as well as long intervals of anomalous gold. The high-grade intercepts typically occur within hydrothermal-magmatic tourmaline matrix breccias and on the margins of tourmaline matrix breccia pipes.

David Greenway, president and chief executive officer of Giant Mining, stated: "This planned multiphase drill and exploration program represents an important next step in advancing Majuba Hill. Our focus is on systematically testing priority copper-silver targets informed by geological mapping, surface sampling and the project's extensive historical data set. Majuba Hill is a large, well-located system in a proven Nevada mining jurisdiction, and this program is designed to refine our understanding of the controls on mineralization and support continued, disciplined exploration. With strong infrastructure, year-round access and a phased approach to drilling, we believe Majuba Hill offers compelling potential as we work to unlock additional value for shareholders and contribute to America's priority of securing a domestic, reliable supply of critical copper and silver."

Breccia zones

Key characteristics typically associated with intrusive-related tourmaline breccia pipes that have been identified include:

• High-grade zones in shingle clast breccias adjacent to sharp breccia contacts and hydrothermal-magmatic breccias;
• Multielement associations (Cu, Ag, Au, Mo, As, and Bi) (copper, silver, gold, molybdenum, arsenic and bismuth);
• Downward flaring geometry (inverted cone);
• Long vertical extent (3,000 feet/1,000 metres);
• Disseminated copper mineralization related to potassic altered intrusions.

Target breccia zones

Three breccia zones (Southern, Ball Park and Northern breccia zones) will be targeted for drilling in the 2026 phase 1 program. The breccia zones are outlined based on recent and historic drilling, 3-D grade and geologic modelling, and surface geochemistry. The zones are located at the intersection of northwest and northeast structural corridors.

In the Southern breccia zone detailed underground mapping and sampling is in progress to identify breccia margins in the accessible underground workings. Surface mapping is also in progress on the Ball Park breccia and will soon commence in the Northern breccia zone to delineate the breccia margins.

Additional surface sampling and reconnaissance geologic mapping is planned for the DeSoto copper-gold Section 4 targets. These targets have been outlined by the continuing exploration of the company from property-wide soil geochemistry and geophysics. The recent breccia and project reviews have highlighted these areas for additional follow-up that may warrant drilling during phase 2.

Breccia formation at Majuba Hill

Hydrothermal-magmatic breccias and breccia pipes at Majuba Hill formed by the explosive release of gas-rich fluids from cooling magma bodies. The breccias are composed of breccia clasts (which are broken fragments of the surrounding rocks) that are cemented together by a matrix material (which is typically composed of quartz, tourmaline, sulphides and oxidized sulfides). Core from hole MHB-2 is an excellent example of a mineralized breccia.

The importance of breccias related to copper deposits has been documented since the early 1900s. Modern exploration and mining have developed very descriptive conceptual models with key features.

Breccia targeting at Majuba Hill

Giant has assembled a comprehensive exploration database from all drilling, geologic mapping, soil and rock geochemistry, and geophysics. The recent breccia study reviewed the 3-D geology and mineralization modelling from the database, identifying numerous breccia bodies and mineralized breccias that are priority targets for the 2026 program. Phase 1 drilling in 2026 will comprise six to eight holes totalling up to 5,000 feet of core targeting breccia margins across three main tourmaline breccia zones. With the goal of cutting both sides of the pipes into high-grade copper (plus/minus silver and gold).

Two fences are planned for the Southern breccia zone. Drill fences will be located to explore for the continuation of the high-grade intercepts in core holes MHB-30 and MHB-32 and to extend the mineralization further up along the margins of the pipe to the peak of Majuba Mountain. MHB-30 and MHB-32 returned high-grade copper and silver as well as highly anomalous gold. The high-grade intercepts correlate with the margins of the breccia pipes (see Table 1).

One fence of holes is planned for the Ball Park breccia zone. Surface mapping of limonite matrix breccias and recent soil geochemical sampling (see news release dated Nov. 19, 2025) indicates the conical shaped hill could be the uppermost portion of a tourmaline breccia pipe. Historic drill hole MF-02 intersected:

• 120 feet (36.6 m) at 0.51 per cent Cu and 21.7 grams per tonne Ag from 260 ft to 380 ft (79.2 to 115.8 m).

A geological description is not available for hole MF-02. However, MM-17, an adjacent core hole drilled:

• 94 ft (28.65 m) of tourmaline breccia from 302.8 to 396.8 ft (92.3 to 120.9 m).

One fence of holes is planned to test the Northern breccia zone. These are stepout holes to test prominent outcropping tourmaline breccia and anomalous Cu, Mo and silver in historic soil geochemical anomaly.

Majuba Hill's critically important characteristics are as shown in the attached table.

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.

We seek Safe Harbor.
