Giant Mining Expands New Copper Discovery at Majuba Hill Copper-Silver-Gold Project, Nevada with AI-Driven Drill Program as Phase 2 Exploration Begins

Executive Summary

• Giant Mining Corp. announces the commencement of its 2025 Phase 2 Exploration Program at the Majuba Hill Copper-Silver-Gold Project in Nevada, leveraging a porphyry-driven, magmatic-hydrothermal breccia model.
• The company released final assay results for the fifth and final drill hole (MHB-36) of the Spring 2025 Phase 1 Core Program, confirming the effectiveness of AI-driven targeting strategies by ExploreTech.
• MHB-36 intersected significant copper mineralization, including a 1.5 ft interval grading 1.21% Cu, validating the presence of hypogene copper in the Southern Zone Breccia Corridor.

Key Details

• Phase 2 Exploration Program Highlights:
  • Southern Breccia Zone: Integration of drill-defined breccia zones into the 3D digital model and copper mineralization.
  • Northern Breccia Zone: Comprehensive surface mapping, core data analysis, and addition of 93 new soil samples to evaluate the zone’s extent.
  • Ball Park Breccia: Utilization of historical drill data to delineate potential high-grade breccia-hosted mineralization.
  • 789 Resistivity Target: Deployment of ExploreTech’s AI-driven geophysical modeling to refine IP/resistivity targets.

Notable Quotes

• David Greenway, CEO: “The final assay results from MHB-36 confirm the effectiveness of our AI-driven targeting strategy at Majuba Hill... ExploreTech’s proprietary geophysical modeling successfully identified a high-potential breccia zone in the Southern Corridor, expanding our understanding of Majuba’s copper mineralization. With these results in hand, we are confident that our Phase 2 program will build on this momentum and further unlock the district-scale copper, silver, and gold potential of Majuba Hill in Nevada.”
• Buster Hunsaker, Consulting Geologist: “The ExploreTech process gives Giant Mining a solid vectoring tool. With this AI-driven process, the Company can utilize the extensive property-wide, IP/Resistivity database. The presence of the copper (as chalcopyrite) is directly related to the magmatic-hydrothermal breccias and the ExploreTech process pointed us straight to the anomalous zone.”
