Heritage Mining restarts drilling at Melba

Executive Summary

• Heritage Mining has resumed drilling at its Melba property in Northeastern Ontario, targeting historic high‑grade intercepts of up to ~14.24 g/t Au over ~4.11 m from ~85 m depth.
• The restart is part of a systematic exploration program that follows strict QA/QC protocols and utilizes PhotonAssay analysis by ISO‑certified laboratory Paragon Geochemical.
• No economic evaluation has been completed; the project currently holds no declared resources or reserves.

Key Details

• Target Intercept: Historical drill results show up to ~14.24 g/t Au over ~4.11 m from approximately 85 m below surface.
• Project Size: Melba property comprises roughly 3,886 ha of claim and lease land along the Ross fault (a splay of the Porcupine‑Destor zone).
• Location: Approximately 22 km NE of Kirkland Lake and 90 km SE of Timmins, Ontario. Nearby historic mines include Grey Fox (~22 km) and Ross (~16 km), each with >1 M oz Au production.
• Drilling Methodology: NQ core is recovered; cores are boxed, sealed, logged, and sampled per a detailed QA/QC protocol. Samples are split 1:1, with one half retained as witness and the other sent for analysis.
• Laboratory Analysis: Gold assays performed by PhotonAssay at Paragon Geochemical (Timmins), ISO/IEC 17025:2017 accredited. Preparation codes include INV‑SAM, PREP‑PKG; analytical code Au‑PA01 covers 0.015–350 ppm Au. Multielement ICP‑MS may be added on selected samples.
• QA/QC Measures: Standards and blanks constitute ≥10 % of total samples; internal lab QA/QC also applied. All disclosed assay results have passed Heritage’s quality controls.
• Qualified Person: Mitch Lavery, P.Geo., strategic adviser, reviewed and approved the technical information per NI 43‑101 standards.
• Management 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,” said Peter Schloo, President, CEO & Director.
