Giant Mining Intersects High-Grade Copper at Majuba Hill:
169.5 ft of 0.41% Cu Including 40 ft of 1.36% Cu and 10 ft
at 4.36% Cu, Highlighting Expansion Potential
VANCOUVER, BC — May 22, 2025 — Giant Mining Corp. (CSE: BFG | OTC:
BFGFF | FWB: YW5) (CSE:BFG.WT.A) (“Giant Mining” or the “Company”) is
pleased to announce the results for core hole MHB-32 (“MHB-32”), the first of five holes
completed during Phase 1 of the Spring 2025 diamond drilling program (“Core
Program”) at the Majuba Hill Porphyry Copper-Silver-Gold Project (“Majuba Hill”),
located in Pershing County, Nevada.
MHB-32 intersected two significant copper mineralized zones within a broader interval of
379.5 feet (115.7 m) grading 0.33% Cu and 16.97 ppm Ag, from 510 to 889.5
feet (155.5 to 271.1 m). These results extend the known mineralization deeper and
further north than previous drilling. The two key intervals, detailed in Table 1, are:
• 85 feet (25.9 m) at 0.64% Cu and 50.89 ppm Ag from 510 to 595 feet
(155.5 to 181.4 m)
• 169.5 feet (51.7 m) at 0.41% Cu and 9.51 ppm Ag from 720 to 889.5 feet
(219.5 to 271.1 m), including:
o 40 feet (12.2 m) at 1.36% Cu and 13.33 ppm Ag from 780 to 820
feet (237.7 to 249.9 m), containing a higher-grade section of:
o 10 feet (3.0 m) at 4.36% Cu and 35.65 ppm Ag from 805 to
815 feet (245.4 to 248.4 m)

The primary objective of the Core Program was to expand the known zones of copper
mineralization and advance the Majuba Hill Project toward completing a Mineral Resource
Estimate (“MRE”). A total of five drill holes, MHB-32 through MHB-36, were completed for
a combined 5,484.5 feet (1,671.68 meters) of core drilling (Table 2).

David Greenway, CEO of Giant Mining, commented: “We're very excited by the
strong results from the first hole of our Phase 1 drilling program at Majuba Hill. Nevada
continues to prove itself as a world-class mining jurisdiction, ideally positioned to support
the ‘America First’ policy and bolster domestic resource security. With global copper
demand soaring—highlighted by BloombergNEF’s recent forecast of a $2.1 trillion
requirement for raw materials by 2050—Majuba Hill offers a compelling, homegrown
solution to help meet America’s significant and growing consumption of copper. We're very
pleased with what we've accomplished so far and can't wait to get back on the ground for
Phase 2.”

MHB-32 Key highlights include:
• Intersected strong supergene copper enrichment at shallower depths in the upper
significant interval (above the historic workings) from 510-595 ft (155.4-181.4
meters). (See Figure 2).
• Deep extension of high-grade supergene copper enrichment.
• Strong supergene enrichment and chalcopyrite-bearing clasts and chalcopyrite-
bearing matrix in deeper portions of magmatic-hydrothermal breccia.
• Northward extension of supergene copper enrichment
MHB-32 Summary
Core Hole MHB-32 was completed to a total depth of 889.5 feet (271.1 meters). The drill
hole intersected historic workings at 569 feet (173.43 meters). However, by reducing from
HQ to NQ size core the hole was extended to 889.5 feet (2714.1 meters). Above the
historic workings the hole intersected copper-bearing magmatic-hydrothermal breccias
with supergene enriched copper mineralization, including azurite, malachite, chalcocite,
and traces of cuprite (See Figure 2).

Below the historic workings the copper-bearing, magmatic-hydrothermal breccias
gradually transitioned from supergene copper mineralization into strongly oxidized copper
sulfides with primary, unoxidized chalcopyrite near the bottom of the hole. From 569 to
715 feet (173.43-217.93 meters) MHB-32 went through leached zones and the outer
portions of the magmatic-hydrothermal breccia back into higher grade supergene
enrichment copper enrichment and the copper-mineralized portion of the magmatic-
hydrothermal breccia. (See Figure 3).

Majuba Hill’s critically important characteristics are as follows:
6
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 113 road km (70 miles)
southwest of Winnemucca, Nevada, and 251 km (156 miles)
northeast of Reno. Access is by well-maintained county
roads from the Imlay, Nevada exit on U.S. Interstate 80,
and traveling 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 to more remote
projects
History: Historical Producer
Drilling:
Approximately 89395 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 2025 Drilling Campaign
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. Drill core samples are sawn in half lengthwise and one half is placed in labeled
cloth sample bags. Sample bags 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.
All 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
7
reference material pulps.

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
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.
