GIANT MINING BEGINS DRILLING AI-DESIGNED FIFTH HOLE AT 2025 MAJUBA HILL COPPER-SILVER-GOLD PROJECT WITH EXPLORETECH

Drilling of hole MHB-36 is under way. MHB-36 is the fifth hole of Giant Mining Corp.'s 2025 diamond core drilling program, currently under way at the Majuba Hill porphyry copper-silver-gold deposit 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 degrees. The hole was designed by Exploration Technologies Inc. (ExploreTech) using its proprietary artificial-intelligence-assisted geophysical modelling 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 data set for refining the deposit model and informing subsequent resource estimation.

David Greenway, chief executive officer 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 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 remodelling of existing geophysical data sets 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 drill hole 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 add 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 data sets is a significant new exploration tool and has already been applied in several cases; some are viewable on ExploreTech's website.

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, United States -- a globally top-ranked mining jurisdiction, ranked No. 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 kilometres (70 miles) southwest of Winnemucca, Nev., and 251 kilometres (156 miles) northeast of Reno. Access is by well-maintained county roads from the Imlay, Nev., exit on U.S. Interstate 80 and travelling 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 with more remote projects.

History:  historical producer

Drilling:  83,930 feet of drilling to date; rough replacement value of drilling $10.4-million (U.S.) in development costs

Mineralization:  The project shows indications of a potentially large copper-silver-plus-or-minus-gold-mineralized body with many features in common with both large porphyry copper, silver and gold projects.

Expandability:  The induced polarization survey, deep drilling and stepout drilling indicate significant expansion potential, with mineralization open in all directions.

Fully financed:  secured financing 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 such as 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 kilometres) from Reno, Nev. 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.
