Heritage Mining finds more visible gold at Melba

Executive Summary

• Heritage Mining Ltd. confirmed the presence of visible gold in drill core ML3840-001 at its Melba project, located outside the previously modeled internal zone.
• Visible gold was identified at approximately 31 meters depth, with at least four such identifications made so far, enhancing the exploration potential of the project.
• The mineralization occurs in sheared quartz veinlets within a silicified quartz diorite intrusion, accompanied by up to 3% pyrite across a two-meter interval.

Key Details

• Drill Hole: ML3840-001
• Location of Interest: Approximately 31 meters depth.
• Observation: Fine-grained visible gold identified in core.
• Scope: At least four identifications of visible gold have been made thus far.
• Geological Context:
  • Gold occurs in sheared quartz veinlets.
  • Host rock: Silicified quartz diorite intrusion.
  • Associated mineralization: Up to 3% pyrite across a two-meter interval.
  • Zone Status: Outside the current internal model previously announced on Feb. 9 and 10, 2026.
