Major Operational Milestone With First Production

VANCOUVER – K92 Mining Inc. has produced its first commercial grade gold-copper-silver concentrate and plans to imminently commence shipments from its new 1.2 million tonnes per annum (tpa) Stage 3 Expansion process plant at its Kainantu Gold Mine in Papua New Guinea.

The new Stage 3 Expansion Process Plant remains on track for completion of commissioning in the first half of Q4. The process plant was delivered under budget and represents the largest growth capital item for the Stage 3 Expansion, of which 90% has been spent or committed as of September 30, 2025.

John Lewins, Chief Executive Officer and Director, said, “I am very pleased to announce that the Stage 3 Expansion Process Plant has achieved its inaugural production, a major milestone for our Company, our stakeholders, and the country of Papua New Guinea. This achievement is the result of the tireless efforts and collaboration of our workforce, contractors, and partners. I commend our team for successfully bringing this major project online safely, efficiently, and under budget.

This marks an exciting chapter in K92’s history as the Company advances towards Tier-1, mid-tier producer status. Beyond celebrating this milestone, we are excited for the significant long-term benefits that the Stage 3 Expansion will deliver for our employees, communities, and all stakeholders.”
