Giant Mining Intersects Thick Intervals of Oxide Copper at Majuba Hill, Extending Mineralized Breccia Zone
(TheNewswire)
VANCOUVER, BC — JULY 15, 2025 — TheNewswire - Giant Mining Corp. (CSE:BFG | OTC: BFGFF | FWB: YW5 | CSE: BFG.WT.A | CSE: BFG.WT.B) (“GiantMining” or the “Company”) is pleased toreport additional assay results from Phase 1 of the Spring2025 diamond drilling program (the “CoreProgram”) 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 strongbreccia controls and significant high-grade copper mineralization andcorrelate with high-grade intercepts previously identified in coreholes MHB-30 andMHB-32. The primaryobjective of the Core Program was to delineate and better understandthe geometry and extent of the copper-bearing breccia zones. Assayresults and geological interpretation outline a large, distinctcopper-mineralized breccia body at Majuba Hill.
Highlights
Copper within the MineralizedBreccia Body in MHB-34included enriched and primary (hypogene) copper mineralization (seeFigure 2 and Table 1):
500 ft (152.4 m) @ 0.21% Cu from1210-1710 ft (368.8-521.2 m) including165 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 from1505-1560ft (458.7-475.5 m)
Core hole MHB-34 intersected long intervals of copper mineralization withinboth the main Mineralized BrecciaBody and the MarginalBreccia Zone (Figure 2). Meanwhile, holesMHB-33 and MHB-35 focused on shallower portions ofthese zones (Figure 5). The new results confirm, extend, and furtherdefine the continuity and significance of breccia-controlled coppermineralization across the project.
As previously announced in the May 22, 2025 news
release, corehole MHB-32 intersectedtwo significant copper-mineralized zones within a broader interval of379.5 feet (115.7 m)grading 0.33% Cu and 16.97 ppm Ag, from 510 to 889.5 feet (155.5 to271.1 m). These results extended knownmineralization deeper and further north than previous drilling. Key intercepts from MHB-32 include:
85 feet (25.9 m) grading0.64% Cu and 50.89 ppm Ag,from 510 to 595 feet (155.5 to 181.4 m)
169.5 feet (51.7 m) grading0.41% Cu and 9.51 ppm Ag,from 720 to 889.5 feet (219.5 to 271.1m), including:
40 feet (12.2 m) at 1.36% Cu and 13.33 ppm Ag, from780 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, from805 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 thescale and continuity of breccia-hosted copper mineralization at MajubaHill. With copper emerging as a national security priority under thecurrent U.S. administration, and Nevada ranked as the number onemining jurisdiction in the United States, the stars are aligning forGiant Mining. We’re fully funded for the next phase of drilling, andour team — led by Buster Hunsaker — is eager to launch Phase 2.We’re incredibly proud of the work accomplished so far and excitedabout what lies ahead as we advance our mission to help reshoreAmerica’s copper supply."

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 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 will be retrieved from ALS
Labs.

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.
