Giant Mining Corp. announced the successful completion of Phase 1 of its 2025 spring diamond core drilling program ("Core Program") at the Majuba Hill Porphyry Copper-Silver-Gold Project ("Majuba Hill") in Pershing County, Nevada. Equipment demobilization has concluded, and the Company is now preparing for comprehensive analysis of drill core samples, aiming to define geological controls and further delineate mineralization.
A total of five drill holes, MHB-32 through MHB-36, were completed for a combined 5,484.5 feet (1,671.68 meters) of core drilling. This brings the cumulative total of drilling at Majuba Hill to 89,395 feet (27,247.5 meters), which will significantly enhance the Company's geological model and support future deposit development. The primary objective of the Core Program was to step out from and expand the known zones of copper mineralization and advance the Majuba Hill Project toward completing a Mineral Resource Estimate ("MRE").
All drill core was transported to Giant Mining's secure core facility in Elko, Nevada, where it was logged, sawn, and sampled by Company personnel. The samples were submitted to ALS Global Services ("ALS Labs") for geochemical analysis, with sample preparation completed at their Elko facility and final assaying conducted at their laboratory in Vancouver, British Columbia. Key highlights include: MHB-32 - Starting with a Bang.
Core Hole MHB-32 was completed to a total depth of 889.5 feet (271.1 meters). The hole intersected copper-bearing magmatic-hydrothermal breccias with secondary copper minerals, including azurite, malachite, and chalcocite. These transitioned into strongly oxidized copper sulfides, with primary, unoxidized chalcopyrite near the bottom of the hole.
MHB 34 - Native Copper Encounter. Core Hole MHB-34 was drilled to a total depth of 1,963 feet (598.3 meters). The hole encountered persistent native copper, cuprite, and chalcopyrite mineralization in its deeper sections, with native copper observed beyond 1,850 feet.
These results indicate a robust porphyry system at depth and suggest proximity to a primary copper sulfide source. MHB 36 - An A.I. Driven Step Out Discovery and Potential Deposit Extension. The fifth and final drill hole of the Core Program, MHB-36, was planned for a total depth (TD) of 1,000 feet (304.8 meters).
This hole was designed by Exploration Technologies ("ExploreTech") using its proprietary AI-predicted target intersected promising mineralization, suggesting a potential new discovery and was a meaningful step-out from previously defined zones. Notably, MHB-33 was drilled to a depth of 1,963 foot and encountered significant native copper, expanding understanding of the scale and potential of the Majuba Hill Copper-Silver-Gold system. The company now eagerly await assay results from ALS Labs as work toward completing an NI 43-101 Mineral Resource Estimate to support future development plans.
