Giant Mining Intersects ExploreTech-Predicted Mineralization, Indicating Potential Extension or New Discovery at Majuba Hill Copper-Silver-Gold Project, Nevada
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.

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.
Figure 4: Location for AI-Assisted Drill Hole Targeting for MHB-36 Designed by ExploreTechDavid 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 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.
