Australian lithium developer Pilbara Minerals has agreed a strategic relationship with South Korean group POSCO regarding the second stage of its Pilgangoora lithium project in Western Australia.

The agreement involves POSCO initially receiving 80,000 t/yr of chemical spodumene concentrate. This will rise to 240,000 t/yr if the two companies establish a joint venture to produce 30,000 t/yr of lithium carbonate or hydroxide. The plant will be in South Korea.

POSCO will make an equity investment of A$79.6mn ($63.2mn) in Pilbara Minerals, which will help to fund the second stage of the Pilgangoora project.

The relationship with POSCO will transform Pilbara Minerals into a vertically integrated producer of lithium-ion battery materials and capture value across the mining and downstream processing stages, chief executive Ken Brinsden said.

The deal includes Pilbara Minerals making an investment decision on the second stage of Pilgangoora by 31 December, 2018. It must receive all regulatory approvals by 31 March. 2019, and produce first concentrate by 31 March, 2020.

The life of mine offtake agreement with POSCO means that 30pc of lithium concentrate output from stage one and stage two of Pilgangoora will go to the South Korean market.

PIlbara has offtake deals with China's General Lithium Corporation and Jiangxi Ganfeng Lithium Company for the first stage of Pilgangoora. It has a five-year, 75,000 t/yr agreement with China's Great Wall Motors for stage two production.

POSCO is one of South Korea's major industrial groups with interests in steel, engineering, construction, trading and battery metals. It is expanding its capacity to produce battery grade products and materials for the battery metals market in South Korea and Asia.

Its investment in Pilbara Minerals is the first direct investment by a South Korean manufacturer of lithium-ion battery materials into a supplier of spodumene concentrate, facilitating further commercialisation of POSCO's PosLX extraction technology, Pilbara Minerals said.

A definitive feasibility study into the second stage of the Pilgangoora project is underway, which looks to increase ore throughput to 5.0mn t/yr from 2.0mn t/yr.

Stage one of the Pilgangoora project will start producing lithium ore in the second quarter of this year. It will export its first lithium concentrate in the third quarter. First stage concentrate output is expected to be 330,000 t/yr from 2.0mn t/yr of ore. Output will rise to 800,000 t/yr from 5mn t/yr of ore if a go-ahead is agreed for a second stage.

Pilbara has a direct shipping ore agreement with Atlas Iron. This enables it to capitalise on the steep demand for lithium feedstock in the Chinese market and generate early revenue for Pilgangoora.
