Giant Mining continues Majuba Hill work with Respec

Executive Summary

• Giant Mining Corp. is continuing its engagement with Respec Company LLC to integrate 2024 and 2025 diamond core drilling data into the 3D geological model of its Majuba Hill copper-silver-gold project in Nevada.
• The updated interpretation will refine the geometry of breccia bodies, evaluate the impact of new findings on project potential, and guide future drilling strategies, metallurgical studies, and target evaluation.
• The release highlights the project's strategic value, infrastructure, and expansion potential, while also disclosing amended marketing agreements with Gold Standard Media and Interactive Offers.

Key Details

• Respec Engagement Scope: Respec will incorporate core data from drill holes MHB-30 through MHB-36 (from the 2024 program and 2025 spring program) into the Majuba Hill 3-D model.
• Technical Objectives: The work aims to refine breccia body geometry, incorporate silver into the exploration model, and evaluate new target zones including the Northern breccia, Ball Park breccia, and 789 resistivity target.
• Timeline: Respec will perform the updated interpretation and technical review over the next three to five weeks.
• Strategic Impact: The updated model provides a technical foundation for economic potential, supporting the company's strategy to advance Majuba Hill as a key domestic source of copper and silver.
• Project Statistics:
  • Location: Pershing County, Nevada (113 km SW of Winnemucca; 251 km NE of Reno).
  • Size: 9,684 acres.
  • Drilling: Approximately 89,395 feet of drilling to date, with a rough replacement value of $12.1 million (U.S.) at current costs.
  • Mineralization: Indications of a large copper-silver-plus-or-minus-gold mineralized body with features common to large porphyry projects.
  • Expandability: Significant expansion potential indicated by induced polarization surveys, deep drilling, and stepout drilling; mineralization is open in all directions.
  • Financing: Company has secured financing for the next phase of drilling.
• QA/QC Measures: Samples are transported to ALS Labs in Elko, NV, for prep and analysis in North Vancouver, BC. Analysis includes copper, gold, silver, and 33 other elements using fire assay (Au-AA23) and four-acid digestion/ICP-AES (ME-ICP61). Approximately 5% of samples are duplicates or standards.
• Qualified Person: E.L. (Buster) Hunsaker, CPG No. 8137, reviewed and approved the technical information.
• Marketing Agreement Amendment: Giant Mining amended its agreement with Gold Standard Media LLC (dated Sept 10, 2025), increasing the total consideration for marketing services to up to $550,000 (U.S.), an increase of $150,000 from the previous $400,000 commitment. No options or securities will be issued for these services.
• New Marketing Agreement: Giant Mining engaged Interactive Offers LLC (dated July 8, 2025) for digital marketing campaigns with an initial budget of $50,000 (U.S.). Compensation is cash-only, and no options or securities will be issued.
