Giant Mining Submits Core From 1,100-Foot AI Driven Core
Hole MHB-36 -- All Remaining Assays Now Pending from
Spring 2025 Drill Program
VANCOUVER, BC — June 25, 2025 — Giant Mining Corp. (CSE: BFG | OTC: BFGFF
| FWB: YW5) (“Giant Mining” or the “Company”) is pleased to announce that all core
from drill hole MHB-36—completed to a total depth of 1,100 feet (335.3 meters) has been sampled
and submitted to ALS Global Services (“ALS Labs”) for analysis.
This hole was part of the Company’s Phase 1 Spring 2025 Drill Program (“Core Program”), which
comprised five diamond drill holes totaling 5,484.5 feet (1,671.7 meters) at the Majuba Hill Porphyry
Copper-Silver-Gold Project (“Majuba Hill”), located in Pershing County, Nevada. All core has now
been submitted for assay.
This hole was designed using Exploration Technologies, Inc. (“ExploreTech”) and its
proprietary probabilistic, AI-driven geophysical modeling, which strategically enhanced
the Company’s targeting capabilities for this phase of the program. ExploreTech
optimizes drill targeting and field operations, enabling better, faster, and more cost -
effective discoveries.

The Phase 1 program was designed to expand known zones of copper mineralization and advance
the Majuba Hill project toward completion of a Mineral Resource Estimate (“MRE”). Hole MHB-32,
the first of the five holes drilled, returned two significant copper-mineralized zones within a broader
interval of 379.5 feet (115.7 meters) grading 0.33% Cu and 16.97 ppm Ag. Notably, the
results included 169.5 feet of 0.41% Cu, with higher-grade intervals of 40 feet at 1.36% Cu
and 10 feet at 4.36% Cu, indicating that mineralization extends deeper and farther north than
previously known. See Press release May 22, 2025, here.
“With assays pending from holes MHB-34 and MHB-35, and MHB-36, we’re very encouraged by
the progress of our 2025 drill program,” said David Greenway, President & CEO of Giant Mining
Corp. “These results are expected to enhance our evolving deposit model at Majuba Hill, which we
believe is shaping up to be a significant copper, silver, and gold discovery in a top-tier jurisdiction
with strong infrastructure. The project aligns with America's critical minerals and clean energy
priorities. With our Special Warrant Financing now underway, we’re well-positioned to accelerate
development and build long-term shareholder value.”

MHB-36 intersected visual disseminated and vein -hosted chalcopyrite mineralization
within the targeted breccia zone, beginning at a downhole depth of 650 ft (198 m).
Mineralization was observed intermittently continuing beyond 905 ft (274.32 m).

The successful intersection of targeted mineralization, as predicted by ExploreTech’s
AI-driven geophysical modeling, provides a strong foundation for optimizing future drill
programs in 2025, 2026, and beyond.
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 me thod 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.

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.
