Heritage Mining Ltd. has intersected more than 20 visible gold occurrences up to 2mm in drill hole ML3800-004 at the Melba Project in Northeastern Ontario, marking the highest visible gold count recorded in the project's history.

Visible gold was identified between 45m and 54m depth within an approximate 9m-wide shear zone, representing a true width of roughly 6m. The coarse gold occurs as disseminated grains within the mineralised breccia and shear zone.

Drill holes ML3800-003 and ML3800-004 are the most recent holes designed to test an interpreted high-grade gold shoot identified during a structural evaluation of the Melba vein system by advisor Brett Davis. Assays for both holes are currently pending.

“The confirmation of visible gold occurrences within a ~6m wide true width gold-bearing mineralized breccia/shear zone bodes well for the project development at Melba. Brett Davis’s structural interpretation of the inferred high-grade gold shoot appears to be spot-on, with these two recent holes both intersecting visible gold. We look forward to reporting further on our ongoing diamond drilling program and additional milestones in short order.”

Previous drilling in hole ML3800-003 intersected visible gold at two locations within a wider 15.8-metre shear zone. By comparison, hole ML3800-004 delivered a denser concentration of visible gold occurrences across its interval.

“Textures and mineralisation-alteration-veining assemblages are typical of an orogenic gold system that has evolved from ductile deformation conditions through to brittle-ductile. We are in the right address, with the district hosting +1Moz gold deposits in the world-class, highly gold-endowed Timmins-Kirkland Lake area. This is becoming a very interesting project and I look forward to further testing the new structural theory, given the near-term success”

Heritage is earning a 75% interest in the historical Melba Mine, which operated as a past producer during the early-to-mid 1900s. The property encompasses a land package totaling approximately 3,886 hectares situated along the Ross Fault, a splay off of the Porcupine-Destor Fault Zone.

Heritage is continuing its ongoing diamond drilling program at Melba, with assay results for drill hole ML3800-003 expected in late August 2026. The project currently has no mineral resources or reserves, and no economic evaluations have been completed.
