Heritage Mining hits mega quartz vein at Drayton Black

Executive Summary

• Heritage Mining released preliminary drill results from its fall 2025 program at the Zone 3 extension of the Drayton‑Black Lake project, intersecting a mega quartz vein over ~185 m strike with 15.5 m core length.
• The first scout hole (HML25‑016) returned 0.98 g/t Au over 5 m and up to 4 g/t Au over 2 m within sulphide‑bearing quartz, mirroring earlier high‑grade intervals.
• Additional drilling, soil/orientation surveys, and permitting are underway, with further results expected in Q4 2025/Q1 2026.

Key Details

• Drill Hole HML25‑016: Intersected mega quartz vein structure at ~15 m core length (true width not yet determined).
• Vein Extent: Broad zone of granite‑hosted quartz‑vein mineralization extended ~185 m along strike.
• Core Length: 15.51 m of sulphide‑bearing quartz (from 87.49 m to 103.00 m depth); true width unknown.
• Assay Highlights:
• 0.98 g/t Au over 5.00 m starting at 101.00 m depth.
• 1.11 g/t Au over 11.09 m beginning at 115.91 m depth, including a higher‑grade interval of ~4 g/t Au over 2 m near 125 m.
• Mineralogy: Visible sulphides (molybdenite, pyrite) with alteration minerals silica, hematite, and K‑feldspar.
• Additional Holes: Two more holes completed; intersected a major NE‑SW striking linear magnetic feature within the granite—assays pending.
• Program Status: Core logging, splitting, and assay submission in progress.
• Exploration Plans (2025 Fall):
• Soil/till orientation survey near completion; follow‑up survey expected Q4 2025 (weather permitting).
• Outcrop/vein stripping permit obtained for HML25‑013 area—ongoing work.
• Structural study of the mega‑quartz vein system to commence.
• Additional diamond drilling slated for Q4 2025/Q1 2026, nearing completion.
