VANCOUVER, BC — May 19, 2025 — Giant Mining Corp. (CSE: BFG | OTC: BFGFF | FWB: YW5) (CSE:BFG.WT.A) (“Giant Mining” or the “Company”) is pleased to announce 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. Table 1: Majuba Hill 2025 Drill Program Collar Details 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. David Greenway, CEO of Giant Mining, commented: “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.” 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.

This early success confirmed the vertical continuity of the mineralized system and the presence of high-potential breccia-hosted copper zones.

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 Click Image To View Full Size 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-assisted geophysical modeling system to test a high-potential resistivity anomaly delineated in the southern sector of the Majuba Hill project area. The AI-driven targeting approach aimed to identify geologically favorable zones with potential for new copper mineralization beyond the existing mineralization footprint.

Right: Downhole plot of drilling results and ExploreTech prediction, showing predicted probability of sulfide mineralization and the true intersection (dashed grey). Due to the intersection of the sulfides predicted by modeling the hole was extended to 1100 feet (335.28 meters). MHB-36 intersected disseminated and vein-hosted chalcopyrite mineralization within intrusive and magmatic hydrothermal breccias, beginning at a downhole depth of 650 feet (198 meters). Mineralization was observed intermittently beyond 905 feet (274.32 meters), confirming the accuracy of the AI model and highlighting the potential for further extensions of copper-bearing zones in this underexplored area.

Majuba Hill’s critically important characteristics are as follows: Quality Assurance/Quality Control (“QA/QC”) Measures, Chain of Custody The Company utilizes a QA/QC program using best industry practices at the Majuba Hill Project. The samples are placed in cloth sample bags and are transported from the Giant Mining secure warehouse to the ALS Labs Sample Prep Facility in Elko, Nevada. ALS Labs then securely transports the prepared pulps to their analytical lab in North Vancouver, B.C. Drill core samples are sawn in half lengthwise and one half is placed in labeled cloth sample bags. All samples are analyzed for copper, gold, silver, and 33 other elements. Gold is determined by ALS Labs method Au-AA23 which is a fire assay with an AAS finish on a 30-gram split. Copper, silver, and the remaining 31 elements are determined by ALS Labs method ME-ICP61 which is a four-acid digestion and ICP-AES assay. Approximately 5% of the submitted samples are drill duplicates and copper-gold-porphyry commercial standard reference material pulps. The remaining pulps will be retrieved from ALS Labs.
