Quantum Graphite Offtake Deal Targets Large-Scale Australian Supply

Quantum Graphite

Quantum Graphite offtake deal will supply Sunlands Pure Group with 1mn t/yr of graphite flake from the planned Uley mine in South Australia under a binding 20-year agreement.

Quantum Graphite offtake deal could expand significantly after production begins. The company plans to increase annual supply to around 5mn t within seven years of first output, although the mine has not yet been constructed.

Quantum Graphite offtake deal is strategically important because it links Australian mining with downstream processing in South Australia and Oman. This creates a potential non-China graphite supply chain extending from mine to high-purity refined product.

The project still faces substantial execution risk, however. Quantum has not announced a construction timeline for Uley, while both the Eyre Peninsula processing hub and Oman refinery remain planned developments.

Uley Mine Anchors Integrated Graphite Processing Strategy

Quantum plans to send graphite flake from Uley to the proposed Eyre Peninsula Graphite Hub in Port Lincoln, less than 25km from the mine.

The hub is designed to produce 100,000 t/yr of graphite concentrate at 96% purity. Locating initial processing close to the mine could reduce logistics costs and allow more value to remain in South Australia.

Sunlands then plans to export this concentrate to a proposed refinery near Sohar Port in Oman.

The Oman facility is targeting 100,000 t/yr of 99.99% purity graphite concentrate. That purity level would move the material much further downstream and closer to specifications required for advanced industrial and battery applications.

The proposed structure gives Quantum and Sunlands control over multiple processing stages rather than relying only on raw flake exports.

This is increasingly important in graphite because mining capacity alone does not solve supply-chain concentration. Purification and downstream processing remain strategically important bottlenecks.

Scale Ambitions Depend on Financing and Project Execution

The most ambitious part of the agreement is Quantum's plan to increase supply to around 5mn t/yr within seven years of first production.

That would require a very large mining and processing operation compared with the initial hub capacity of 100,000 t/yr of concentrate.

The difference highlights the amount of infrastructure, financing and downstream capacity that would need to be developed if the project reaches its long-term target.

Quantum has contracted Lycopodium to complete front-end engineering design work for Uley, but no construction schedule has been disclosed.

The company also previously received a $300mn letter of interest from the US Export-Import Bank for a proposed South Carolina refinery. The current status of that project remains unclear following the emergence of the Oman development.

The key question is therefore execution rather than resource ambition. Uley must first reach construction, while the Australian and Omani processing facilities must secure financing, permits and customers.

If those pieces align, the project could become an important source of non-China graphite for battery and advanced materials markets.

The Metalnomist Commentary

Quantum's offtake agreement is strategically attractive because it links mining with downstream purification. The real test will be whether the partners can finance and scale the infrastructure needed to convert an ambitious supply target into reliable graphite output.
