Heritage Confirms the Third Visible Gold Occurrence in Core and Extends Drill Hole to Length ~150m at Melba Project

Executive Summary

• Heritage Mining confirmed visible gold in core from drill hole ML3840‑003 at ~72.4 m within an ~8 m shear zone at the Melba Mine Project.
• This is the third occurrence of visible gold in the same shear zone, prompting extension of the hole to a planned depth of ~150 m pending assay results.
• The intercept occurs in a millimeter‑scale gold grain assemblage hosted in a sheared quartz veinlet with strong epidote‑silica‑chlorite alteration, enhancing the project's exploration potential.

Key Details

• Hole & Depth: ML3840‑003 – visible gold observed at 72.40 m; hole depth now being extended to ~150 m due to favorable mineralization.
• Intercept Characteristics: ~8 m interval containing millimeter‑scale gold grains within a sheared quartz veinlet; synformal folding and strong epidote‑silica‑chlorite alteration noted.
• Geological Setting: Sheared felsic volcaniclastic and conglomerate contact; located in an 8 m shear zone on the Ross Fault splay of the Porcupine‑Destor Fault Zone, proximal to historic gold mines (McEwen Mine ~22 km, Ross Mine ~16 km).
• Project Overview: Melba Project covers ~3,886 ha in NE Ontario, ~22 km NE of Kirkland Lake and 90 km SE of Timmins.
• QA/QC Protocols: Core boxed, sealed, labeled; chain‑of‑custody maintained; samples split 1:1 for witness and assay; assays performed by Paragon Geochemical (PhotonAssay, detection range 0.015–350 ppm). Standards/blanks ≥10% of samples; results verified by Qualified Person.
• Qualified Person: Mitch Lavery, P.Geo., Strategic Advisor – reviewed and approved the scientific/technical disclosure per NI 43‑101.
• Future Steps: Assays pending; company will update stakeholders on additional exploration results shortly.
