St Barbara has unveiled a comprehensive pre-feasibility study for its Simberi gold mine in Papua New Guinea, confirming a robust 200,000 ounces per annum gold production over a 13-year mine life.
The study outlines a total production of 2.2 million ounces from the 2025–26 financial year (FY26) through to FY38.
The expansion plan includes the development of a sulphide processing plant, expected to enhance recovery rates and extend the mine’s operational life. This initiative follows the successful commissioning of the new sizer and the appointment of an operations advisor earlier this year, indicating St Barbara’s commitment to advancing the project.
“Our ongoing work continues to show that the Simberi Expansion Project is a robust opportunity to deliver value for St Barbara shareholders,” St Barbara managing director and chief executive officer Andrew Strelein said.
“Our current work shows a project with significantly higher production averaging 220kozpa over eight years, a lower operating cost and a mine life extending to 13 years without including any exploration targets.”
For St Barbara, the next steps involve progressing towards a definitive feasibility study, with the company aiming to secure the necessary approvals and funding to commence full-scale development.
“Our focus now is on the completion of the feasibility study to support a financial investment decision, which we are targeting for (the first half of) FY26,” Strelein said.
“In the meantime we continue to advance early works to allow a seamless transition into fullscale development.”
St Barbara remains focused on delivering value to its stakeholders while maintaining a commitment to environmental stewardship and community engagement in the regions where it operates.
