Giant Mining Begins Drilling AI-Designed Fifth Hole at 2025

Majuba Hill Copper-Silver-Gold Project with ExploreTech

VANCOUVER, BC — May 9, 2025 — Giant Mining Corp. (CSE: BFG | OTC:

BFGFF | FWB: YW5) (CSE:BFG.WT.A) (“Giant Mining” or the “Company”) is

pleased to announce that drilling of Hole MHB-36 (“MHB-36”) is underway. MHB-36 is

the fifth hole of the 2025 diamond core drilling program (the “Core Program”), currently

underway at the Majuba Hill Porphyry Copper-Silver-Gold Deposit (“Majuba Hill”) in

Pershing County, Nevada.

As previously reported, the fifth drill hole is planned to a total depth (TD) of 1,000 feet,

inclined at 70 degrees from horizontal, on an azimuth of 220°. The hole was designed by

Exploration Technologies (“ExploreTech”) using its proprietary AI-assisted geophysical

modeling system to target a high-potential resistivity anomaly delineated in the southern

sector of the project area. Upon completion of these five drill holes, the Company’s

cumulative exploration and development drilling will exceed 88,000 feet, providing a

significantly enhanced geological and geophysical dataset for refining the deposit model

and informing subsequent resource estimation.

David Greenway, CEO of Giant Mining, commented: We’re excited by the progress of the

2025 drill program and the decision to add this fifth hole at Majuba Hill. Designed with

ExploreTech’s AI, the hole targets a high-potential southern resistivity anomaly. Majuba

Hill’s scale and potential continue to impress, and this phase of drilling is critical to unlocking

further value for our shareholders. With the growing demand for domestic U.S. copper,

the timing couldn’t be better. Our team has never been more confident in advancing

Majuba Hill’s full potential.”

As previously stated, the primary objective of the Core Program is to expand the known

3

zones of copper mineralization at Majuba Hill and advance the project toward a new Mineral

Resource Estimate (“MRE”).

Tyler Hall, President of ExploreTech, stated: “After close collaboration with the Giant Mining

team, we launched a sophisticated computational workflow that ran continuously for a

week, using powerful cloud computing with Majuba’s extensive geophysical and geological

data. Our proprietary Engine AI system tested thousands of models to pinpoint the most

promising targets and optimize drill trajectories, in conjunction with the Giant Mining team.

This approach not only improves drilling efficiency but also allows for continuous refinement

as new data comes in. We’re excited to see the Engine in action at Majuba and look forward

to the drilling results in the coming weeks. It’s been a pleasure working alongside the

talented team at Giant Mining to help unlock the full potential of the Majuba

Mountain project.”

About Exploration Technologies Inc.

ExploreTech’s AI approach is specifically designed to combine surface geology and drilling

results with computationally intensive remodeling of existing geophysical datasets to

optimize targeting of covered targets. The process quickly generates thousands of solutions

that cluster on the best fits between the geological and geophysical data and then

generates drillhole trajectories designed to cut those clusters most effectively.

ExploreTech first combines the geological concept with AI geophysical simulation to identify

and locate where the source of a geophysical anomaly actually lies. This is done by testing

thousands of possible explanations (models) for anomalies measured at the surface and

selecting only those that closely match the real-world geophysics. The selected models of

the combined geology and geophysics cluster around the most likely location of the

anomaly. The program then evaluates the clusters in three dimensions to determine the

optimal drilling trajectory to pierce as many of the target anomalies as possible. The entire

process can be rerun as drill results for specific targets, or additional geophysical surveying,

adds new information allowing improved vectoring to the best mineralized parts of a given

ore system. This use of AI to reveal and reinforce target anomalies in existing geophysical

datasets is a significant new exploration tool and has already been applied in several cases,

some are viewable at www.exploretech.ai.

The Company will provide regular updates as the drill program progresses, including assay

results, geological observations, and any significant developments encountered during

drilling. These updates will keep shareholders and stakeholders informed on the

advancement of the Majuba Hill project and its potential to support a future resource

estimate.

Majuba Hill’s critically important characteristics are as follows:

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

5

Drilling:

Approximately 88,795 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

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.
