The announcement, released on 2 Apr 2026, marks one of the most significant milestones in the Company’s recent history, confirming that construction will proceed immediately.
The Lingbao Gold Simberi deal, first announced on 10 Dec 2025, sees Lingbao acquire a 50% strategic interest in the New Simberi Gold Project. With the SBM ASX share price having recovered strongly over the past 12 months, the completion of this transaction gives investors a clearer picture of what lies ahead for the Company and its flagship development asset.
A$389 Million Lands and St Barbara Has Never Been Better Funded
The A$389 million cash consideration received from Lingbao comprises the agreed A$370 million plus an A$19 million working capital and cash holdings adjustment. St Barbara’s cash balance now stands at A$504 million as of the announcement date, excluding A$26 million retained as the starting cash position of the jointly owned subsidiary.

- The total construction cost of the New Simberi Gold Project is US$333 million, inclusive of approximately US$13 million already spent to 31 Mar 2026
- St Barbara is fully funded for its 50% share of construction costs from its current cash balance of A$504 million
- The Company anticipates no tax leakage on the A$0.5 billion gain on sale, preserving the full financial benefit for shareholders
- The Kumul Transaction, once finalised pending Papua New Guinea regulatory approvals, will further cement the three-way ownership structure between St Barbara, Lingbao, and Kumul Mineral Holdings Limited
- Construction of the New Simberi Gold Project is set to proceed immediately following FID approval, with mining throughput targeted to double from 10 million metric tons per annum to approximately 20 million metric tons per annum
Construction Starts Now and the Simberi Gold Project FID Is Officially Approved

A Mine Built to Run for 13 Years and Produce at Scale
The New Simberi Gold Project involves a major expansion of the existing Simberi mining and processing operation in Papua New Guinea. The expansion will allow treatment of significant Ore Reserves of higher grade sulphide ore, with mining scheduled to increase to approximately 20 million metric tons per annum of material from the current rate of 10 million metric tons per annum.
The Project is anticipated to deliver production rates of more than 200,000 ounces per annum, at an expected All-in Sustaining Cost of between US$1,100 and US$1,400 per ounce.
The New Simberi Gold Project is anticipated to have a mine life extending to 13 years based on Ore Reserves alone, without including any conversion of Mineral Resources or exploration targets.
The Voices Behind the Deal and What Both Leaders Said at Completion
St Barbara Managing Director and CEO Andrew Strelein welcomed the completion as a transformative moment for the Company and its shareholders.
“Today’s completion of the Lingbao transaction and approval of the FID represents a major milestone for St Barbara. The New Simberi Gold Project is a long-life, low-cost operation fully funded for development and will increase production to over 200 kozpa. This transaction, along with the FID approval, significantly de-risks the development of the project and unlocks long-term value for the Company and shareholders. The project will also deliver significant benefits to the local communities and PNG stakeholders,” Strelein said.

Lingbao Chairman Mr Wang Pinran also spoke directly to the significance of the milestone and the partnership ahead.
“We are delighted to see the completion of our transaction. Following the approval of the Final Investment Decision, the New Simberi Gold Project is fully funded and will be fast-tracked into development to achieve over the 200 kozpa target. Lingbao, St Barbara and Kumul will work together to deliver great value to our shareholders, as well as significant benefit to the local community and PNG stakeholders,” Wang said.

One Piece Still Pending as the Kumul Transaction Awaits PNG Approval
Completion of the transaction with Kumul Mineral Holdings Limited remains the only outstanding step. The Kumul Transaction awaits Papua New Guinea Government regulatory approvals from the Independent Consumer and Competition Commission and from the National Executive Council.
St Barbara has indicated it anticipates Kumul will receive formal approvals from both bodies imminently. Critically, any delay in completing the Kumul Transaction does not impact the Lingbao transaction or the Simberi Gold Project FID, both of which are now formally complete.

Industry Outlook
The global gold mining sector continues to attract significant capital as bullion prices remain elevated, driving renewed interest in development-stage projects with clear production pathways.
Papua New Guinea remains an important gold jurisdiction, with major international producers and strategic investors increasingly seeking long-life, low-cost assets in the Asia-Pacific region.
The entry of Lingbao Gold Group as a 50% partner in the New Simberi Gold Project reflects the growing appetite among Asian mining groups for exposure to Tier 1 development assets outside China.
Future Direction and Impact on SBM Investors
For investors tracking the SBM ASX share price, the completion of the Lingbao Gold Simberi deal removes one of the most significant near-term uncertainties that had been overhanging the stock. St Barbara is now fully funded, construction has been approved, and a A$0.5 billion gain on sale is expected to flow through the FY26 Financial Results with no tax leakage.
The New Simberi Gold Project’s targeted production rate of more than 200,000 ounces per annum, combined with a 13-year mine life and an AISC range of between US$1,100 and US$1,400 per ounce, positions the project as a material long-term earnings contributor.
The Simberi Gold Project FID confirmation means the critical question for investors now shifts from funding and approvals to construction execution and timeline. St Barbara is advised by Macquarie Capital (Australia) Limited as financial adviser and Mallesons as legal adviser on the transaction.
