Giant Mining Intersects ExploreTech-Predicted

Mineralization, Indicating Potential Extension or New

Discovery at Majuba Hill Copper-Silver-Gold Project, Nevada

VANCOUVER, BC — May 12, 2025 — Giant Mining Corp. (CSE: BFG | OTC:

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

pleased to provide the following update on Hole MHB-36 (“MHB-36”). MHB-36 is the fifth

and final hole of the 2025 diamond core drilling program (the “Core Program”), at the

Majuba Hill Porphyry Copper-Silver-Gold Deposit (“Majuba Hill”) in Pershing County,

Nevada. The hole was completed to 1100 feet (335.3 m). The Company further announces

it is fully funded for a follow-on drill program at Majuba Hill.

Notably, Hole MHB-36 was strategically designed using Exploration Technologies, Inc.

(“ExploreTech”) and its proprietary probabilistic AI-driven geophysical modeling,

significantly enhancing the Company’s targeting capabilities for this phase of the program.

ExploreTech’s software automatically optimizes drill targeting—enabling companies to

make smarter, faster, and more cost-effective drilling decisions.

and the true intersection (dashed grey).

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).

As stated in the May 9, 2025 news release, the fifth drill hole originally targeted

a depth of 1,000 ft (305 m), inclined at 70° with an azimuth of 220°. The hole

was designed by ExploreTech using its proprietary AI-assisted geophysical modeling

system to target a high-potential resistivity anomaly identified 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 ft (26,822 m), providing a

significantly enhanced geological and geophysical dataset to refine the deposit model and

guide subsequent resource estimation.

The intersection of the targeted mineralization, as predicted by ExploreTech’s AI-assisted

geophysical modeling, provides a critical foundation for optimizing the design of the

Company’s subsequent drill programs planned for 2025, 2026, and beyond.

David Greenway, CEO of Giant Mining, commented: “The future is now. ExploreTech’s

cutting-edge AI technology, combined with the expertise of our technical team at Giant

Mining, is transforming how we explore and unlock the full potential of Majuba Hill. The AI

models predicted mineralization starting between 600 and 700 ft, and our team intersected

the target zone within just 50 ft of those projections—a remarkable validation of this

technology. Artificial intelligence is reshaping the future of mineral exploration and deposit

development, not only in the U.S. but worldwide. We’re proud to be at the forefront of this

transformation, investing in innovation today that will drive success at Majuba Hill through

2026 and well beyond.”

The primary objective of the Core Program is to expand the known zones of copper

mineralization at Majuba Hill and advance the project toward a new Mineral Resource

Estimate (“MRE”).

Tyler Hall, Co-Founder and President of ExploreTech, stated: “We are thrilled to see these

drilling results; the nature of this new sulfide zone could link the breccias above with large

porphyry style mineralization below. This step-out drillhole expands the potential at

Majuba. Furthermore, with these results, ExploreTech’s drilling recommendations have

correctly intersected the source of geophysical anomalies 7 out of 7 times, and this marks

6

the first time we are sharing real-world results with the broader public. We’ve repeatedly

seen our Inverter and Driller tools, built on the ExploreTech Engine, improve interpretation

timelines and drilling accuracy on multiple deposit styles, with multiple geophysical

techniques. This collaboration with the Giant Mining team has not only delivered

remarkable accuracy in targeting mineralization but is also setting the stage for continuous

optimization as new drilling data is incorporated. We’re proud to support Giant Mining as

they advance Majuba Hill into 2026 and beyond, and we look forward to the discoveries

that lie ahead.”

About Exploration Technologies Inc.

ExploreTech’s AI approach uses Inverter and Driller; two APIs built on top of The

ExploreTech Engine cloud computing orchestration system. Inverter is specifically designed

to combine surface geology and drilling results with computationally intensive modeling of

existing geophysical datasets to optimize targeting of covered targets. Driller 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,

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

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.
