Heritage Mining finds gold zone at Drayton-Black Lake

Executive Summary

• Heritage Mining Ltd. confirmed broad gold mineralization within a newly discovered ~74-metre-wide quartz vein system at its Drayton-Black Lake project, specifically at the Zone 3 extension.
• Scout drilling (2025 program) targeted a magnetic anomaly extending ~4km along strike; the program consisted of four holes totaling 1,105.5m, with two holes intersecting the quartz vein structure.
• The company plans to drill an additional 10 holes along a two-kilometre strike length of the magnetic lineament to further test the potential of the mega-quartz vein system.

Key Details

• Drill Hole HML25-013 Intersections:
  • 0.98 g/t Au over 5.00 m from 101.00 m.
  • 1.11 g/t Au over 11.09 m from 115.91 m, including a higher-grade interval of 4 g/t Au over 2 m from 125 m.
  • Intersected a strongly deformed quartz vein up to 74 metres in core length (true width unknown).
• Drill Hole HML25-014 Intersections (Anomalous values outside vein zone):
  • 0.87 g/t Au over 0.46 m from 310.82 m.
  • 0.63 g/t Au over 0.52 m from 315.75 m.
• Program Statistics:
  • Total holes drilled: 4.
  • Total metres drilled: 1,105.5 m.
  • Holes intersecting vein structure: HML25-011 and HML25-013.
  • HML25-010 and HML25-012 confirmed locally elevated gold values per previous reports; HML25-014 missed the structure due to dip direction.
• Geological Context:
  • The quartz vein system is associated with a magnetic anomaly extending approximately 4 km along strike and up to 200 m in width.
  • Evidence of multiple stages of deformation, fluid ingress, alteration, and sulphide deposition observed within the vein system.
  • Anomalous gold values found outside the quartz vein zone inside the granite batholith, supporting the mineralized vein system model.
• Future Plans:
  • Proposed additional 10 holes to test along a two-kilometre strike length of the magnetic lineament.
  • Complete program proposal for the rest of 2025 to be communicated in short order.
• Project Status:
  • No economic evaluations completed.
  • No mineral resources or reserves currently defined.

Notable Quotes

• Peter Schloo, President, CEO and Director: "We are very pleased with the discovery of such a wide quartz vein structure. Our limited drilling has now confirmed a broad zone of gold mineralization associated with the megaquartz vein structure. The company is excited by the potential this vein system exhibits, and we look forward to further communicating the next steps as well as findings on our other projects to the market in short order."
• Brett Davis, Structural Geologist Consultant: "The intersection of very wide (approximately 74 m wide in core length, HML25-013) strongly deformed quartz vein in drill holes from Zone 3 extension in the Lake of Bays batholith was a great proof of concept for our geology/mineralization model... The return of assays showing a composite interval of 0.98 g/t Au over 5.00 m and 1.11 g/t Au over 11.09 m (including four g/t Au over two m from 125 m) in hole HML25-013 provides further encouragement for discovery and support of our model."
