Giant Mining Continues Engagement of RESPEC Engineering
to Incorporate 2024 and Spring 2025 Core Drilling into
Modeling at Majuba Hill Copper-Silver-Gold Project, Nevada
VANCOUVER, BC — June 9, 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 it is continuing its engagement
with RESPEC Company LLC (“RESPEC”) of Reno, Nevada. RESPEC will
incorporate drilling data from the 2024 diamond core and from the 2025 spring
diamond core drilling program (the “Core Program”) at the Majuba Hill
Porphyry Copper-Silver-Gold Project (“Majuba Hill”) in Pershing County,
Nevada, into the database used for the Technical Report for the Majuba Hill
Copper Project, Pershing County, Nevada, USA. (the “Report”).
The Report had an effective date of March 14, 2023, a Report Date of June 20,
2023, was amended on February 4, 2025, and was authored by Jeffrey M. Bickel
C.P.G. RESPEC Company LLC and W. Joseph Schlitt, PhD, QP.
New assays and geologic data from the effective date of the Report will be
compiled and incorporated to accommodate all of the observed geology and
provide the best understanding for the mineralization at Majuba Hill.
David Greenway, CEO of Giant Mining, commented: "The 2025 drill season at Majuba
Hill was our most ambitious and technically advanced to date. Strong early visual
mineralization exceeded our expectations and led to the addition of a fifth hole—MHB-36—
guided by AI-assisted geophysical modeling. This AI-targeted hole intersected promising
mineralization and marks a significant step-out from previously identified zones, indicating
the potential for a new discovery. Meanwhile, core hole MHB-34 reached a depth of 1,963
feet and encountered native copper, reinforcing the scale and depth potential of the Majuba
Hill Copper-Silver-Gold system. We’re excited to continue advancing the project with
RESPEC as we move forward with Majuba Hill.”

The primary objective of the 2025 Core Program was to step out from and expand the
known zones of copper mineralization and advance the Majuba Hill Project toward
completing a mineral resource estimate. All drill core was transported to Giant Mining’s
secure core facility in Elko, Nevada, where it was logged, sawn, and sampled by Company
personnel. The samples were submitted to ALS Global Services (“ALS Labs”) for
geochemical analysis, with sample preparation completed at their Elko facility and final
assaying conducted at their laboratory in Vancouver, British Columbia.
Key highlights include:
MHB-30 (September 24, 2024 news release)
High-grade copper was sampled from core hole MHB-30 (“MHB-30”) that was
clearly associated with magmatic-hydrothermal, copper-bearing breccia zone.

MHB-32
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 2, 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)
Core Hole MHB-32 was completed to a total depth of 889.5 feet (271.1 meters). The hole
intersected copper-bearing, magmatic-hydrothermal breccias with secondary copper
minerals, including azurite, malachite, and chalcocite. These transitioned into strongly
oxidized copper sulfides, along with primary, unoxidized chalcopyrite near the bottom of
the hole.

This early success confirmed the vertical continuity of the mineralized system and the
presence of breccia-hosted copper zones.

MHB 34 – Native Copper Encounter
Core Hole MHB-34 was drilled to a total depth of 1,963 feet (598.3 meters). The hole
encountered persistent native copper, cuprite, and chalcopyrite mineralization in the
deeper sections, with native copper observed beyond 1,850 feet.

These visual results indicate a robust enrichment zone related to a porphyry system at
depth and suggest proximity to a primary copper sulfide source.
MHB 36 – An A.I. Driven Step Out Discovery or Potential Deposit Extension
The fifth and final drill hole of the Core Program, MHB-36, was planned for a total depth of
1,000 feet (304.8 meters). This hole was designed by Exploration Technologies
(“ExploreTech”) using its proprietary AI-assisted geophysical modeling system to test a
high-potential resistivity anomaly delineated in the southern sector of the Majuba Hill
project area. The AI-driven targeting approach aimed to identify geologically favorable
zones with potential for new copper mineralization beyond the existing mineralization fo
Due to the intersection of the sulfides predicted by modeling the hole was extended to
1100 feet (335.28 meters). MHB-36 intersected disseminated and vein-hosted
chalcopyrite mineralization within intrusive and magmatic hydrothermal breccias,
beginning at a downhole depth of 650 feet (198 meters). Mineralization was observed
intermittently beyond 905 feet (274.32 meters), confirming the accuracy of the AI model
and highlighting the potential for further extensions of copper-bearing zones in this
underexplored area.
