Pan African Resources has completed a definitive feasibility study for a ZAR3.68 billion Soweto tailings project with a projected 29.55% real ungeared IRR. The proposed operation could add up to 40,000 ounces of annual gold production, but financing, permits and board approval remain ahead of a targeted December 2026 investment decision.
- ZAR3.68 billion estimated project capital after ZAR718 million of value engineering
- 35,000oz to 40,000oz of annual gold production over approximately 15 years
- Post-tax NPV13 of ZAR1.85 billion at a US$3,550/oz gold price assumption
- Final investment decision targeted for December 2026, subject to approvals and financing
- Mogale complex peak production could rise to approximately 100,000oz annually
Soweto project clears feasibility hurdle
Pan African Resources PLC (ASX:PAF) has put a price tag and return profile on its next major tailings opportunity, completing the definitive feasibility study for the Soweto Tailings Retreatment project in Gauteng. The proposed 600,000-tonne-per-month operation is estimated to produce 35,000 to 40,000 ounces of gold a year and about 561,000 ounces over an approximately 15-year project life.
At a gold price assumption of US$3,550 an ounce, the study produces a post-tax NPV13 of ZAR1.85 billion, a real ungeared internal rate of return of about 29.55% and a post-commissioning payback period of roughly three years. Those figures describe the project economics under the stated assumption, rather than a guarantee of future returns.
Existing Mogale infrastructure cuts capital intensity
The project is designed to sit alongside Pan African’s existing Mogale Tailings Retreatment operations, using established elution, carbon regeneration, electrowinning and gold-smelting infrastructure. That shared processing footprint is central to the economics: the company’s value-engineering review reduced estimated capital from approximately ZAR4.40 billion to ZAR3.68 billion, a saving of about ZAR718 million while retaining the planned throughput, production and operating design.
The development would process Soweto Cluster tailings acquired through the Mintails transaction. Those facilities contain Mineral Reserves of approximately 108 million tonnes grading 0.28 grams per tonne, or about 0.98 million ounces of gold. The project also includes hydraulic mining infrastructure, pumping stations, around 18 kilometres of slurry and water pipelines, and a dedicated new tailings storage facility designed to comply with the Global Industry Standard on Tailings Management.
Permits and funding now set the timetable
If developed, Soweto could lift peak annual gold production from the Mogale complex to approximately 100,000 ounces. Pan African also says the retreatment work would accelerate rehabilitation of historical tailings facilities and surrounding areas on the West Rand, although the environmental and water approvals required to build the project are not yet complete.
The environmental impact assessment and permitting process is described as well advanced, with pipeline servitude approvals in place, while the Water Use Licence application remains in progress. Pan African expects the principal environmental authorisations during FY27 and is targeting a final investment decision in December 2026, subject to board approval, project financing and the required statutory authorisations. Construction is expected to take about 28 months from that decision.
Bottom Line?
The DFS gives Pan African a sizeable, infrastructure-backed growth option, but the investment case now turns on permitting, financing and whether the project economics hold as the gold-price assumption changes.
Questions in the middle?
- Will Pan African secure the required project financing without materially changing the proposed capital structure or development timetable?
- How will the project economics respond to gold prices below or above the assumed US$3,550 an ounce?
- Can the Water Use Licence and remaining environmental approvals arrive in time for a December 2026 final investment decision?
