Heritage Mining Ltd. has confirmed high-grade gold mineralization at the Melba Project in Northeastern Ontario, returning 15.57 g/t gold over 9 metres from a depth of 43 metres in drill hole ML3800-004.

The intercept, which has an estimated true width of approximately 6 metres, includes a higher-grade core yielding 28.98 g/t gold over 4.80 metres. Assays from the drilling test an interpreted high-grade gold zone identified during a structural evaluation of the Melba vein system by advisor Brett Davis.

The mineralization is hosted within a zone comprising multiple centimeter to metre-scale quartz-rich shear zones that locally display breccia textures and visible gold grains up to 2 millimetres in size.

To support continuous multi-season operations at the property, Heritage established the Melba Project's first-ever year-round access in July 2026 by upgrading approximately 5.5 kilometres of former winter access trails.

“The assays result from ML3800-004 are encouraging, confirming our new structural theory. We look forward to expanding the Melba Project footprint through systematic exploration and communicating results to our stakeholders. Drilling program remains ongoing at the time of this press release.”

— Peter Schloo, President, CEO and Director of Heritage

Heritage is currently drilling hole ML3800-005 and intends to advance to Phase 2 drilling to target down-dip and along-strike extensions of the multi-shear and breccia zone. The technical team is also working with newly acquired magnetic, electromagnetic, and LiDAR datasets to identify additional prospective targets across the property.

The Melba Project has not completed any economic evaluations and currently holds no mineral resources or reserves.
