Heritage Mining prepares for fall exploration at DBL

Executive Summary

• Heritage Mining has mobilized an aggressive fall 2025 exploration program targeting the newly identified Zone 3 extension mega‑quartz vein system at its flagship Drayton‑Black Lake project.
• The program includes a soil/till orientation survey, follow‑up sampling, receipt of a stripping permit for area HML25‑013, structural studies, and planned scout diamond drilling slated for Q4 2025/Q1 2026.
• A broad gold zone has been confirmed within an approximately 74‑m wide quartz vein system that extends ~4 km strike length, prompting further systematic exploration.

Key Details

• Discovery: Approximately 74‑metre‑wide quartz vein system (true width unknown) with associated magnetic anomaly extending ~4 km along strike and up to 200 m in width.
• Exploration Activities – Fall 2025:
• Aggressive soil/till orientation survey over Zone 3 extension – currently in progress.
• Follow‑up soil/till survey (targeted for Q4 2025) to identify pathfinder chemistry and near‑surface mineralization footprints across Zone 3, Alcona, Zone 10, and New Millennium targets.
• Outcrop/vein stripping permit received for area above HML25‑013 – permitting underway.
• Structural study of the mega‑quartz vein system initiated.
• Scout diamond drilling planned for Q4 2025/Q1 2026, contingent on soil/till and structural results; may commence earlier pending internal evaluation.
• Management Comment: “We are grateful to our technical team for earlier‑than‑expected availability to further explore the newly discovered Zone 3 extension mega‑quartz vein structure systematically… I would like to thank the exploration team for their strong efforts,” – Peter Schloo, President, CEO & Director.
• Qualified Person: Stephen Hughes, P.Geo., strategic adviser, reviewed and approved the technical information per NI 43‑101.
• QA/QC Protocols: Detailed description of core handling, sample preparation (PhotonAssay at ALS Canada), multielement assay procedures, and quality control standards (≥10 % standards/blanks).
• Economic Status: No economic evaluations completed; the project currently has no declared resources or reserves.
