HERITAGE INTERSECTS MEGA QUARTZ VEIN STRUCTURE 185M ALONG STRIKE AT ITS DRAYTON-BLACK LAKE PROJECT

Heritage Mining Ltd. has released preliminary results from its fall 2025 diamond drill program at Zone 3 extension, Drayton Black Lake project. The first hole has intersected the mega quartz vein structure approximately 185 metres along strike. Two additional holes have been completed and are currently being processed, they intersected a major northeast-southwest-striking linear magnetic feature that is within the granite. The first scout hole (HML25-016) intersected the mega quartz vein structure at approximately 15 metres in core length (true width unknown).

2025 fall exploration program -- zone 3 extension drill highlights:

• Drilling extended a broad zone of granite hosted quartz vein mineralization approximately 185 m;
• Vein width is approximately 15.51 m in core length (from 87.49.00 m to 103.00 m), true width unknown;
• Locally visible sulphides, including molybdenite and pyrite, occurring with alteration comprising silica, hematite and K-feldspar;
• 15.51 m of sulphide-bearing quartz similar to gold mineralization intervals from HML25-013 press released Sept. 9, 2025, and highlighted below:
  • 0.98 gram per tonne Au (gold) over 5.00 m from 101.00 m;
  • 1.11 g/t Au over 11.09 m from 115.91 m including: four g/t Au over two m from 125 m.
• Drill core is being logged, split and sent for assay as soon as possible.

2025 fall exploration plans -- Zone 3 extension:

• Soil/till orientation survey over Zone 3 extension area -- near completion;
• Follow-up soil/till survey -- success based on orientation survey expected Q4 2025, weather permitting;
• Outcrop/vein stripping permit received above HML25-013 -- in progress;
• Initiate a structural study of the mega-quartz vein system;
• Diamond drilling Q4 2025/Q1 2026 -- near completion.

"We are extremely pleased to have extended such a broad vein zone in the first scout hole at Zone 3 extension prospect fall 2025 exploration program. Heritage's geologists have observed additional intense sulphide-bearing quartz similar to that associated with gold mineralization from HML25-013, 185 m away. This is an excellent start to Heritage's fall scout drill program. We also look forward to communicating additional drill results, soil orientation program and stripping results at the Zone 3 extension target in due course," commented Peter Schloo, president, chief executive officer and director of Heritage Mining.
