Giant Mining Plans Up to 10,000-Foot Multi-Phase Drill
Program at Majuba Hill Copper-Silver Project, Nevada
VANCOUVER, BC — January 30, 2026 — Giant Mining Corp. (CSE: BFG |
OTC: BFGFF | FWB: YW5 | CSE: BFG.WT.A | CSE: BFG.WT.B. ) (“Giant
Mining” or the “Company”) is pleased to announce the Company is planning
Up to 10,000 Feet (3,048 Meters) of drilling in a multi phased drill program
(“Drill Program”) and exploration program at the Company’s 9,684 acre
flagship Majuba Hill Project Copper-Silver-Gold Project in Pershing County,
Nevada.
The multi phased Drilling and Exploration Program is anticipated to include
• Phase 1 – Up to 5,000-foot (1,524 meters) 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 meters) Core Drill Program
The multi phased drill ing 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 2024-2025 exploration results,
including all drilling, surface geologic mapping, and surface geochemical
sampling his identified numerous mineralized breccia bodies (See NR dated
January 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 CEO of Giant Mining “This planned multi-
phase 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
2
project’s extensive historical dataset. 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)
• Downward flaring geometry (inverted cone)
• Long vertical extent (>3000 feet/1000 m)
• 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, 3D grade and geologic modeling, and
surface geochemistry. The zones are located at the intersection of northwest and
northeast structural corridors (see Figure 1).
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 (see Figure 1). These targets have
been outlined by the ongoing 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, sulfides, and oxidized sulfides) . Core from hole MHB- 2 is an excellent
example of a mineralized breccia (see Figure 2).

The importance of breccias related to copper deposits has been documented since the
early 1900’s. Modern exploration and mining have developed very descriptive
conceptual models with key features. Figure 3 shows the stages of development of a
tourmaline breccia pipe.

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 3D geology and mineralization modeling 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 totaling 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 (+/-silver and gold).
Two fences are planned for the Southern Breccia Zone (see Figure 4). 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 (see Figure 5).
Surface mapping of limonite matrix breccias and recent soil geochemical
sampling (See NR November 19, 2025) indicates the conical shaped hill could
be the uppermost portion of a tourmaline breccia pipe (see Figure 3). Historic
drill hole MF-02 intersected:
• 120 ft (36.6 m) @ 0.51% Cu and 21.7 g/t Ag from 260 ft to 380 ft (79.2-
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 (92.3-120.9
m)

Majuba Hill’s critically important characteristics are as follows:
Location:
Nevada, USA — a globally top-ranked mining jurisdiction,
ranked #1 in the Fraser Institute’s 2022 Annual Survey of
Mining Companies.
Project Size: 9,684 Acres
Infrastructure:
The Majuba Hill property is located 113 road kilometers (70
miles) southwest of Winnemucca, Nevada, and 251 kilometers
(156 miles) northeast of Reno. It is accessible via well -
maintained county roads from the Imlay, Nevada exit on U.S.
Interstate 80, followed by a 23-mile drive west. People, roads,
power, and water are fundamental considerations for
infrastructure, and Majuba Hill already benefits from a strong
foundation in all these areas. This existing infrastructure
provides a significant advantage, offering substantial cost
savings compared to more remote projects.

History: Historical Producer
Drilling:
Approximately 89,395 feet of drilling to date. Rough
replacement value of drilling USD $12.1 Million using current
costs.
Mineralization:
The project shows indications of a potentially large Cu – Ag +/-
Au mineralized body with many features in common with both
large porphyry copper, silver, and gold projects.
Expandability:
The IP survey, deep drilling, and step-out drilling indicate
significant expansion potential, with mineralization open in all
directions.
Fully Financed: The Company has secured funding for its next phase of drilling
at Majuba Hill.
