Heritage Mining plans Drayton-Black Lake exploration

Executive Summary

• Heritage Mining Ltd. announced the discovery of a broad gold zone within a newly identified, approximately 74-metre-wide mega-quartz vein system at the Zone 3 extension of its flagship Drayton-Black Lake (DBL) project.
• The company plans an aggressive exploration program including soil/till orientation surveys, outcrop/vein stripping, and structural studies, with follow-up surveys expected in Q4 2025.
• Scout diamond drilling is scheduled to commence in Q4 2025 or Q1 2026 to further evaluate the structural discovery and prioritize targeting methods.

Key Details

• Discovery Dimensions: The newly discovered Zone 3 extension mega-quartz vein system is approximately 74 metres wide (true width unknown) and extends for approximately four kilometres along strike length, with a width of up to 200 metres at its widest point.
• Geological Context: The vein system is associated with a magnetic anomaly.
• Exploration Activities:
  • Soil/Till Survey: An aggressive soil/till orientation survey is underway over the Zone 3 extension area. A follow-up soil/till survey is expected in Q4 2025, contingent on the success of the orientation survey.
  • Stripping: A permit for outcrop/vein stripping has been received for the area above hole HML25-013. Stripping and follow-on sampling are planned for the 2025 exploration program.
  • Structural Study: A structural study of the megaquartz vein system is being initiated.
  • Drilling: Scout diamond drilling is planned for Q4 2025/Q1 2026. The company may initiate drilling earlier depending on internal evaluation.
• Technical Methodology:
  • Sampling: Drill core is systematically split in half using a diamond saw. Sample lengths are typically 1.0 metre, adjusted to a minimum of 0.5 metre.
  • Analysis: Samples are analyzed for gold using PhotonAssay at ALS Canada Ltd. (detection range 0.03 ppm to 350 ppm). Multielement assays (ICP-MS) may be performed on selected samples.
  • QA/QC: Standards and blanks account for a minimum of 10% of samples. All results have passed stringent quality control protocols.
• Project Status: The company has not completed any economic evaluations, and the project currently has no resources or reserves.

Notable Quotes

• "We are eager to further explore the newly discovered Zone 3 extension megaquartz vein structure systematically. Our team has developed a comprehensive approach to further exploring this area as well as broader exploration programs before winter. I would like to thank the exploration team for their strong efforts in the discovery of a such wide vein system," commented Peter Schloo, president, chief executive officer and a director of Heritage Mining.
