Giant Mining Intersects Thick Intervals of Oxide Copper at
Majuba Hill, Extending Mineralized Breccia Zone
VANCOUVER, BC — JULY 15, 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 report additional assay results
from Phase 1 of the Spring 2025 diamond drilling program (the “Core
Program”) including core holes MHB-33, MHB-34, and MHB-35, completed
at the Majuba Hill Porphyry Copper-Silver-Gold Project (“Majuba Hill”)
in Pershing County, Nevada.
These results from the Core Program confirm strong breccia controls and
significant high-grade copper mineralization and correlate with high-grade
intercepts previously identified in core holes MHB-30 and MHB-32. The
primary objective of the Core Program was to delineate and better understand
the geometry and extent of the copper-bearing breccia zones. Assay results
and geological interpretation outline a large, distinct copper-mineralized
breccia body at Majuba Hill.
Highlights
Ø Copper within the Mineralized Breccia Body in MHB-34 included enriched
and primary (hypogene) copper mineralization (see Figure 2 and Table 1):
o 500 ft (152.4 m) @ 0.21% Cu from 1210-1710 ft (368.8-521.2 m)
including:165 ft (50.3 m)@ 0.24% from 1280-1445 ft (390.1-440.4
m)
and; 205 ft (62.5 m) @ 0.27% Cu from 1605-1710 ft (458.7-521.2
m)
with; 55 ft (16.8 m) @ 0.41% Cu from1505-1560 ft (458.7-475.5
m)
Core hole MHB-34 intersected long intervals of copper mineralization within
both the main Mineralized Breccia Body and the Marginal Breccia Zone
2
(Figure 2). Meanwhile, holes MHB-33 and MHB-35 focused on shallower
portions of these zones (Figure 5). The new results confirm, extend, and
further define the continuity and significance of breccia-controlled copper
mineralization across the project.
As previously announced in the May 22, 2025 news release, core hole
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
extended known mineralization deeper and further north than previous
drilling. Key intercepts from MHB-32 include:
• 85 feet (25.9 m) grading 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) grading 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), which contains:
§ 10 feet (3.0 m) at 3.6% Cu and 35.65 ppm Ag, from
805 to 815 feet (245.4 to 248.4 m).
David Greenway, CEO of Giant Mining, commented: "The assay results
from MHB-33, MHB-34, and MHB-35 are very positive and continue to validate
the scale and continuity of breccia-hosted copper mineralization at Majuba
Hill. With copper emerging as a national security priority under the current
U.S. administration, and Nevada ranked as the number one mining jurisdiction
in the United States, the stars are aligning for Giant Mining. We’re fully funded
for the next phase of drilling, and our team — led by Buster Hunsaker — is
eager to launch Phase 2. We’re incredibly proud of the work accomplished so
far and excited about what lies ahead as we advance our mission to help
reshore America’s copper supply."

Native Copper in Breccia. 1540-1545 feet/0.62% Cu. (See Table 1)
Ø Copper within the Marginal Breccia in MHB-34 included an oxide and
enriched interval of:
o 135 ft (41.1 m) @ 0.14% Cu from 625-760 ft (190.5-231.6 m)
4
including: 10 ft (3.0 m) @ 0.40% Cu from 665-675 ft (202.7-205.7
m)
Ø Copper Mineralization in MHB-34 extended the Mineralized Breccia Body
to at least 1640 vertical feet (500m) below the top of Majuba Mountain (see
Figure 2)
o Mineralized Breccia Body remains open at depth
Ø Copper intersected in MHB-34 returned 0.09% Cu over the entire 1,963-
foot (598.3 m) length of MHB-34, which when combined with silver results
has a copper equivalent value of 0.13% CuEq (Table 1).

Additional Highlights
Ø MHB-35
o Drilling intersected 90 ft (27.4 m) @ 0.09% Cu from 115-205 ft
(35.1-62.5 m). The hole is strongly clay altered in partially leached,
hydrothermal-magmatic breccias that comprise the Mineralized Breccia
Body (Figure 2). Below the mineralization is a significant zone of
copper mineralization in MHB-32 that graded 379.5 feet (115.7 m) @
0.33% Cu and 16.97 ppm Ag from 510 to 889.5 feet (155.5 to 271.1 m).

Ø MHB-33
o The Marginal Breccia intersected in MHB -33 identified the upper,
western extents of the Mineralized Breccia Body mined in the historic
Copper Stope (see Figure 5). Drilling intersected leached copper
mineralization including 35 ft (10.7 m) @ 0.09% Cu from 5 to 40 ft
(1.5-12.2 m) with numerous 5 foot (1.5 m) intervals of 0.1% copper
(see Table 1).
