The latest news from Pilbara Minerals
The last time the ASX heard price sensitive news from Pilbara Minerals was on 11 May, when the company announced it intends to enter a joint venture with technology company Calix Ltd (ASX: CXL).
The two companies signed a memorandum of understanding to partner to develop a midstream lithium chemicals refinery.
The first step of development will be a scoping study that will assess a new refining process.
Currently, Pilbara Minerals processes its mined ore into spodumene before shipping it to customers who then produce lithium for lithium-ion batteries.
If the companies can fine tune the refining process, Pilbara Minerals could produce lithium in-house – creating an Australian lithium-ion supply chain.
Despite the seemingly positive news, the Pilbara Minerals share price fell 3.82% lower on the day the news was released.
Luckily, it's since bounced back.
