Calix and Pilbara Minerals execute joint venture

Calix and Pilbara Minerals have executed a formal joint venture agreement for an innovative decarbonised lithium refining project that aims to create a new, high value and low carbon intensity lithium product in the Pilbara. The joint venture follows a successful joint initial scoping study, and a close working relationship built over the past 18 months.

Calix Managing Director and CEO, Phil Hodgson said, “Calix is delighted to formally announce our joint venture agreement with Pilbara Minerals for the development of a sustainable, high value mid-stream lithium product.

“Calix is focused on decarbonising our essential industries, utilising our core technology’s ability to electrify industrial processing, and minimise the waste and CO2 footprint of minerals.”

“We are excited to join forces with Pilbara Minerals and formalise our close working relationship built over the past 18 months. We will apply our combined capabilities to generate a more sustainable and valuable Australian lithium product.”

Dale Henderson


Pilbara Minerals’ Managing Director and CEO, Dale Henderson agreed, “It’s a great privilege to enter this partnership with Calix. The Mid-stream project has the potential to be a game changer for our industry.

“If successful, we will be able to deliver a superior product to market, that will attract a premium compared to spodumene concentrate, as well as a reduction in Scope 3 emissions within the lithium supply chain.”

An innovative “mid-stream” process

The “mid-stream” project aims to produce a superior lithium export product via Calix’s calcination technology for sustainable processing of minerals.

The proposed renewably powered at-mine processing innovation is targeting a refined lithium salt product that greatly reduces the cost, waste, and CO2 footprint of Australian lithium, creating a significantly higher value export product.

The project includes the potential development of a demonstration plant at Pilbara Minerals’ Pilgangoora Project and is supported by A$20m in Australian Government funding announced under the Modern Manufacturing Initiative. A Financial Investment Decision on the proposed demonstration plant is planned before the end of FY23.

Australia currently produces nearly half the world’s lithium, with the global market for lithium carbonate and equivalents projected to grow six times by 2030. Industrial decarbonisation tailwinds also continue to drive demand for renewably powered, low waste processing solutions for the materials of our future economy. A successful “mid-stream” project will enable the joint venture to license the technology to the global spodumene processing industry.
