Minbos Resources (ASX:MNB) has signed a non-binding memorandum of understanding (MoU) with South Africa-based Foskor to test Minbos’ phosphate rock for commercial suitability.
Foskor owns and operates a phosphoric acid-based fertiliser plant in Richards Bay, South Africa.
Currently, Foskor sources the phosphate rock for the plant from its mine located in Phalaborwa, but it is considering supplementing it with alternative phosphate rock sources.
Under the MoU, the two companies will undertake a series of bulk samples and trials on phosphate rock from Minbos’ Cabinda Project in Angola.
If testing proves successful, it will pave the way for discussions around a potential offtake agreement.
Minbos Managing Director Lindsay Reed says the company has been engaged with Foskor for some months as the two companies discussed how a possible collaboration would work.
Logistics and technical due diligence activities are also underway to establish the compatibility of the Cabinda phosphate rock and the timing of the logistics infrastructure at Porto do Caio.
Construction at the port remains on track, with the opening of the first berth slated for December 2025.
This will allow exports from Cabinda to begin in 2026.
“The combination of an earlier than anticipated completion of the new deepwater port at Caio and the ability of the company to build in the stage-two expansion as part of the initial construction has allowed both companies to progress their discussions,” Reed says.
