K92 Mining Inc. has announced the first production of commercial-grade gold-copper-silver concentrate from its new 1.2 million tonnes per annum (tpa) Stage 3 Expansion Process Plant at the Kainantu Gold Mine in Papua New Guinea, marking a major operational milestone for the Company.
During the Official Inauguration Ceremony held on site on 16 October, the Prime Minister of Papua New Guinea James Marape witnessed a gold pour at the new plant, which produced 458 ounces of doré.
Also in attendance were Minister for Mining Rainbo Paita, other distinguished members of Parliament, officials from the Eastern Highlands Provincial Government, heads of government departments and agencies, landowner association leaders including Bilimoia Landowner Association Chairman Busa Sio and Associated Landowners Association Chairman Noka Tinko, as well as representatives from the diplomatic corps, the business community, and project partners.
The new Stage 3 Expansion Process Plant — delivered under budget — represents the largest capital investment under K92’s Stage 3 Expansion program, with 90% of total costs spent or committed as of September 30, 2025. Commissioning remains on track for completion in the first half of Q4.
K92 Chief Executive Officer and Director John Lewins said the achievement marks a pivotal moment for the Company and its stakeholders.
“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,” Lewins said.
“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," he added.
Lewins noted that the presence of the Prime Minister, Minister for Mining, and other key officials underscores the strong partnership between K92 and the PNG Government.
“We were deeply honoured to have the Prime Minister of Papua New Guinea, the Hon. James Marape, along with the Minister for Mining, Hon. Rainbo Paita, and other senior government and community representatives attend the Official Inauguration Ceremony. Their continued partnership and support have been instrumental to the success of the Kainantu Gold Mine," he said.
Lewins concluded by emphasising that this milestone positions K92 for future growth.
“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," the executive said.
