Giant Mining Soil Sampling Expands Mineralized Breccia
Footprint with Anomalous Copper and Silver at Majuba Hill
Copper-Silver-Gold Project
VANCOUVER, BC — November 19, 2025 — 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 that the results from 96
new soil samples have extended the footprint of the copper and silver
mineralized breccia bodies identified in the 2024-2025 core drilling programs.
Twenty-one samples out of the 96 Ball Park Soils returned >100 ppm Copper
with a maximum value of 397 ppm Cu. 24 out of the 96 returned greater than 2
ppm Silver with a maximum of 9.5 ppm Ag (see Table 1 and Figure 1).
Table 1: 2025 Ball Park Breccia Soil Survey Summary Statistics
The 96 samples in the Ball Park Soil Survey were collected to fill in a gap in the
existing 3,412 sample soil grid. The anomalous copper results outline a zone
with potential to extend the footprint of copper mineralization up to 1,000 feet
eastward (see Figure 2).
David Greenway, President and CEO of Giant Mining, commented, “These new
soils demonstrate the potential for expanding the Majuba Hill mineralization. Our
Technical Program continues to expand the geologic framework that supports
our drill planning and improvements in the Geological Model by RESPEC. I am

Significance of Soil Results
Multiple Copper in Soils - Zone >100 ppm Cu are oriented northwest. These
zones generally align with the Northwest Fault Corridors that are emerging as
fundamental controls to the breccia bodies in the Southern Breccia Zone and the
Northern Breccia Zone (see Figure 2 and Figure 3). Additionally, multiple Silver
in Soils - Zones >1.1 ppm are also aligned along the Northwest Fault Corridors.
The silver zones coincide with the copper as well (see Figure 4).
The multiple overlapping copper, silver, fault corridor zones, and breccia body
zones are the same as the overlapping features at the Southern Mineralized
Breccia body where the company has reported on numerous copper and silver
intersections in drilling including MHB-30 which assayed (September 24, 2024

• 218.0 feet (66.4 meters) of 1.35% Cu and 73.4 g/t Ag from O to 218 feet
o Including: 74.0 feet (22.6 meters) of 2.6% Cu and 30.1 g/t Ag from
140 to 214 feet (42.7-66.2 meters)

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
5
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: Secured funding for next phase of drilling at Majuba Hill
Quality Assurance/Quality Control (“QA/QC”) Measures, Chain of Custody
The Company utilizes a QA/QC program using best industry practices at the Majuba Hill
Project. The samples are placed in cloth sample bags and are transported from the Giant
Mining secure warehouse to the ALS Labs Sample Prep Facility in Elko, Nevada. ALS Labs
then securely transports the prepared pulps to their analytical lab in North Vancouver, B.C.
Drill core samples are sawn in half lengthwise and one half is placed in labeled cloth sample
bags. All drill, rock, and soil samples are analyzed for copper, gold, silver, and 33 other
elements. Gold is determined by ALS Labs method Au-AA23 which is a fire assay with an
AAS finish on a 30-gram split. Copper, silver, and the remaining 31 elements are
determined by ALS Labs method ME-ICP61 which is a four-acid digestion and ICP-AES
assay. Approximately 5% of the submitted samples are drill duplicates and copper-gold-
porphyry commercial standard reference material pulps. The remaining pulps are retrieved
from ALS Labs and retained in the Companies secured facility.

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 km) from Reno, Nevada. Majuba Hill is situated in a mining-friendly
6
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.
