Heritage Mining Mobilizes Aggressive Exploration Program at Zone 3 Extension Mega-Quartz Vein System at its Flagship Drayton-Black Lake Project

Executive Summary

• Heritage Mining has mobilized its Fall 2025 exploration program at the newly identified Zone 3 Extension Mega‑Quartz Vein System within the Drayton‑Black Lake Project.
• The program includes an aggressive soil/till orientation survey, permitting for outcrop/vein stripping, a structural study of the vein system, and planned diamond drilling in Q4 2025/Q1 2026.
• A broad gold zone has been confirmed within an approximately 74‑m wide quartz vein associated with a ~4 km magnetic anomaly, prompting further systematic exploration.

Key Details

• Zone 3 Extension Discovery: ~74 m wide quartz vein (true width unknown) linked to a magnetic anomaly extending ~4 km strike length and up to 200 m width.
• Soil/Till Program: Orientation survey underway; follow‑up soil/till sampling targeted for Q4 2025.
• Stripping Permit: Received for area above target HML25‑013; stripping and surface structural evaluation in progress.
• Structural Study: Initiated to evaluate the Mega‑Quartz Vein System’s geometry and controls.
• Diamond Drilling: Scout drilling scheduled for Q4 2025/Q1 2026, contingent on results from soil/till and stripping activities.
• Exploration Scope: Program also targets Alcona, Zone 10, Zone 3, and New Millennium with a terrain‑aware B‑horizon sampling approach.
• Qualified Person: Stephen Hughes, P.Geo, has reviewed and approved the technical information per NI 43‑101 standards.
• QA/QC Protocols: Detailed chain‑of‑custody, sample preparation, and analytical procedures (PhotonAssay at ALS Canada) are in place; standards/blanks constitute ≥10 % of samples.
