Heritage Restarts Drilling Targeting Historical High-Grade at Depths: Up to 14.24g/t Au over 4.11m from ~85m from surface at Melba

Executive Summary

• Heritage Mining announced the restart of its Melba drill program targeting deeper historic high‑grade intercepts.
• Historical drilling previously returned ~14.24 g/t Au over ~4.11 m from ~85 m depth, indicating significant upside potential.
• The company detailed its QA/QC protocols, sampling procedures, and qualified person oversight for the upcoming work.

Key Details

• Project Location: Melba Mine, ~22 km NE of Kirkland Lake and 90 km SE of Timmins, Northeastern Ontario; claim package ≈3,886 ha with one mining lease.
• Historical Intercept: ~14.24 g/t Au over ~4.11 m from ~85 m below surface (Figure 1 & 2).
• Geological Setting: Lies on the Ross Fault, a splay of the Porcupine‑Destor Fault Zone; proximal to historic gold producers McEwen (Grey Fox) and Ross Mine (~22 km and ~16 km away).
• Drill Program Restart: Targeting deeper extensions of the high‑grade zone; aims to expand understanding of mineralized zones.
• QA/QC Protocols:
• Chain‑of‑custody, core boxing, labeling, and sealing at rig site.
• Core cut in half; one half retained as witness sample, other sent for analysis.
• Sampling intervals typically 1 m (minimum 0.5 m) to capture lithological contacts.
• Laboratory Analysis: Samples submitted to Paragon Geochemical (Timmins) using PhotonAssay (ISO/IEC 17025:2017 accredited).
• Preparation codes: INV‑SAM, PREP‑PKG; analytical code Au‑PA01 for non‑destructive gold analysis (0.015 ppm–350 ppm range).
• Additional Assays: Multi‑element ICP‑MS (48MA‑MS) may be performed on selected samples based on gold results.
• QA/QC Controls: Standards and blanks ≥10% of samples; internal lab QA programs applied; results verified by qualified person.
• Qualified Person: Mitch Lavery, P.Geo., Strategic Advisor – reviewed and approved scientific/technical information per NI 43‑101.
• CEO Comment: “The zone intersected historically favourable results with increased grade at depths… we look forward to expanding our understanding of the mineralized zones at Melba and updating our stakeholders on additional exploration results in short order.” – Peter Schloo, President, CEO & Director.

“The zone intersected historically favourable results with increase grade at depths, this is similar to other deposits in the area. We look forward to expanding our understanding of the mineralized zones at Melba and updating our stakeholders on additional exploration results in short order.” – Peter Schloo, President, CEO & Director

Materiality Assessment: Non‑Material – Positive (operational update with no immediate financial impact but positive indication of ongoing exploration activity).
