John Lewins, K92 chief executive officer and director, stated: "K92 celebrated many achievements in 2025 in what was a landmark year for the company as we celebrated our 10th anniversary and successfully completed the commissioning of our new 1.2 million tonnes per annum Stage 3 expansion processing plant. This coincided with a truly historic milestone for the people of Papua New Guinea, as the nation celebrated the Golden Jubilee of its independence in 1975.

"At the end of 2025, K92 was a major employer in Papua New Guinea, with approximately 2,150 employees and permanent contractors, and temporary contractors and casuals bringing our total work force to approximately 3,100. PNG Nationals represented approximately 91 per cent of our operational work force, comprising employees and permanent contractors, supported by priority hiring from local communities. In addition, we have become one of the largest corporate taxpayers among mining companies in the country, with $139.2-million in taxes and royalties paid or accrued in 2025. We are also currently the largest foreign investor in mineral exploration in Papua New Guinea, with $18-million invested in exploration activities in 2025 and a further $31-million to $35-million planned investment in 2026, well positioning the company for continued growth.

"I would like to extend my congratulations to the K92 Mining team and the people of Papua New Guinea for all the momentous milestones that were achieved during the year. These achievements are a testament to the dedication and resilience of the innumerable people who have made them possible. As Papua New Guinea looks to its next chapter, we strongly believe that responsible mining will remain an important driver of sustainable development for the country and its remarkable people. At K92, we will continue to work steadfastly in partnership with all our stakeholders to deliver transformational value for many years to come."
