St Barbara confirms A$389 million deal completion
St Barbara Ltd has completed a major transaction with Lingbao Gold Group, securing A$389 million in funding for the New Simberi Gold Project in Papua New Guinea.

The Company reported a total cash position of A$504 million following the deal, excluding A$26 million retained within the joint venture entity. This strengthened balance sheet provides liquidity for development and future operational needs.
The transaction also marks a key financial milestone for the Company’s expansion strategy in the Pacific region.
Final investment decision unlocks project development
Both partners approved the final investment decision (FID) for the project alongside the transaction completion.
The total construction cost stands at approximately US$333 million, equivalent to about A$500 million. This figure includes around US$13 million already spent as of March 2026.
St Barbara confirmed it has secured full funding for its 50% share of the development costs. Construction activities are expected to begin immediately. The approval of the FID removes a major uncertainty and allows the project to move into its next phase without delay.
Production expansion targets higher gold output
The New Simberi Gold Project aims to expand existing mining and processing operations to handle sulphide ore. The project plans to double mining capacity from 10 million tonnes per annum to about 20 million tonnes per annum.
Production is expected to exceed 200,000 ounces of gold annually once operations reach full capacity.
This increase reflects the transition from oxide to sulphide processing, which typically offers higher recovery rates and improved long-term output. The project positions itself among mid-tier gold producers in the region.

Cost structure supports long-term viability
The Company expects all-in sustaining costs to range between $1,100 and $1,400 per ounce. This cost range aligns with current industry benchmarks for similar operations in the Pacific region. The cost profile indicates a balance between higher processing expenses and improved recovery rates.
The projected mine life stands at approximately 13 years based on existing ore reserves.
This estimate excludes potential upside from further exploration or resource upgrades. The long mine life provides stable production visibility and supports long-term planning.

Joint venture structure balances risk and control
The project operates under a 50-50 joint venture between St Barbara and Lingbao Gold Group. This structure allows both companies to share financial exposure while maintaining equal operational influence.
The partnership combines St Barbara’s regional experience with Lingbao’s financial capacity and technical resources.
This arrangement spreads risk across both parties and improves access to capital. It also supports efficient decision-making during development and production phases.
Financial impact includes a significant accounting gain
St Barbara expects to record an unaudited accounting gain of approximately A$500 million from the transaction in its FY26 financial results. The Company stated that it does not anticipate any tax liability associated with this gain.
The transaction structure enables the Company to unlock value while maintaining partial ownership of the asset.
This approach improves the balance sheet and allows continued participation in future project revenues. The outcome reflects careful financial planning within the deal framework.
Regulatory approvals remain for the related transaction
A separate transaction involving Kumul Mineral Holdings Limited remains subject to regulatory approvals. Authorities in Papua New Guinea, including the Independent Consumer and Competition Commission and the National Executive Council, will review the proposal.
St Barbara expects these approvals to be granted in due course. The Company noted that any delay in this process will not affect the Lingbao transaction or the approved development timeline. This separation ensures that project progress continues without regulatory disruption.

Leadership highlights project milestone and outlook
St Barbara managing director and chief executive officer, Andrew Strelein, described the deal completion and FID approval as a major milestone. He stated that the project is now fully funded and positioned for development.
Lingbao chairman Wang Pinran also confirmed that the investment supports accelerated project execution. Both parties expect the project to move quickly into construction and achieve its targeted production levels.
The New Simberi Gold Project reflects continued investment interest in Papua New Guinea’s mining sector. The combination of funding, technical planning, and regulatory progress places the project on a clear development path.
