DRILL BIT TURNING: HERITAGE MINING GRANTED PERMIT AND COMMENCES DRILLING AT MELBA'S HIGHLY PROSPECTIVE TARGET AREA

Further to its news release dated Oct. 15, 2025, Heritage Mining Ltd. received its exploration permit for its planned diamond drilling program on Dec. 15, 2025. The company is also pleased to announce drilling has commenced at the Melba project, bordering Kirkland Lake Discoveries, a junior exploration company with recent success in 2025.

"We've moved faster than most companies at our stage regarding the Melba project (in-house drilling and core shack operations) and we believe the market is still catching up to the scale of progress we've made. The real value creation comes from what we do next -- executing the near-term milestones we've lined up and continuing to derisk the project step by step. If we deliver the results we're targeting, we see a clear path to building meaningful long-term shareholder value," commented Peter Schloo, president, chief executive officer and director.
