Majuba Hill Successful Completion Of Phase One

VANCOUVER - Giant Mining Corp. reported the successful completion of Phase 1 of its 2025 spring diamond core drilling program at the Majuba Hill Porphyry Copper-Silver-Gold Project 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.

David Greenway, CEO, said, “The 2025 drill season has been our most exciting and technically ambitious to date. We began the program with strong visual mineralization that exceeded expectations, prompting us to add a fifth drill hole—MHB-36—guided by AI-assisted geophysical modeling. This 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 feet and encountered significant native copper, expanding our understanding of the scale and potential of the Majuba Hill Copper-Silver-Gold system. We now eagerly await assay results from ALS Labs as we work toward completing an NI 43-101 Mineral Resource Estimate to support future development plans.”
