o Calix and Pilbara Minerals (PLS) have executed an MOU covering the co-development of "midstream" lithium chemicals refinery utilising Calix's core technology

o The MOU commits the parties to a scoping study on the project, at Pilbara Minerals' cost, covering lithium salt production of up to several thousand tonnes from Pilbara Minerals' spodumene concentrate facility at Pilgangoora

o Following success in the scoping study, Pilbara Minerals and Calix propose to jointly develop a demonstration plant at Pilgangoora, with a view to further commercialising the technology developed

o The project represents a world-first development of a commercial-demonstration-scale, low-emissions lithium salt production facility


At the mine, if we can efficiently calcine a lower-grade spodumene concentrate we should also be able to achieve a higher recovery from the ore body, meaning less mine wastage and lower cost,
said Pilbara Minerals managing director, Ken Brisden
. The
opportunity to produce a higher-value product in Australia should also allow us to capture more of the overall value in the new-energy industry as it develops

Phil Hodgson, Managing Director of Calix, said the successful trials over the course of the past nine months had tested spodumene concentrates of different grades and particle sizes.

This proof-of-concept work demonstrated that the Calix technology was able to achieve >95% conversion of the spodumene ore to an extractable lithium, which is comparable to the conventional rotary kiln process, but with fine, and lower grade, material. Additionally, we carried out these runs on our BATMn electric kiln, providing additional proof of concept for the technology to be run off renewable electricity, such as a solar and/or wind farm.

Calix is partnering in a low carbon research project which has won $39 million in Australian Government funding.


The Heavy Industry Low carbon Transition Cooperative Research Centre (HILT CRC) aims to reduce carbon emissions of Australia's heavy industrial process. Comprising heavy industry players, government and research, the Centre aims to boost the capability of Australian companies to remain globally competitive by capitalising on existing mineral and renewable energy resources to become leading international producers and exporters of low carbon products.


As well as a spread of universities and research centres, core industrial partners include ADBRI, Alcoa, Boral, Fortescue, Grange Resources, Liberty, Roy Hill, and South32.


The CRC will establish hubs in heavy industry regions of Gladstone, the Pilbara, Northern Tasmania, SA's Upper Spencer Gulf, WA's Kwinana and South West regions, the Southern Highlands of NSW and Portland in Victoria.

CXL has executed a MoU with RHI Magnesita, the leading global supplier of high grade refractory products, systems and solutions. The MOU covers the development of a Calix Flash Calciner for use in the production of refractory materials, which will enable CO2 separation for either utilisation or storage.

Under the terms of the MOU, Calix and RHIM have agreed to undertake studies up to and including basic Front End Engineering and Design for a commercial scale demonstration facility at an RHI Magnesita site.


RHI Magnesita and Calix commenced first discussions around the potential for reducing the CO2 footprint of the refractory production process in early 2019. Calix has been processing magnesite, the main raw material in the production of refractories, since 2013 in its Bacchus Marsh facility for water treatment products. The application of Calix technology to refractory products has been the subject of pilot scale test work during 2020, with larger scale test work currently underway.


Separation and storage or reuse of CO2 released from carbonate minerals is a crucial step in decarbonising the refractory industry and thus the production processes of materials such as steel, cement and lime.

another MoU ... ...covering the development of a lime project for lime production, with CO2 capture and multi fuel options, with Tarmac (https://tarmac.com/ ), the UK’s leading sustainable building materials and construction solutions business.


Tarmac is the UK’s leading sustainable building materials and construction solutions business, and a participant in the LEILAC 1 Project with Calix

dipped a bit on FY reports but upward and onward in the couple of days since... $3.60


• Strong growth of 36% in core product sales ($19M) led by an encouraging performance from the Calix US water business which was successfully integrated into the Group, contributing to both sales growth and positive operating cash earnings. The Company is well placed to execute its expansion plans across the US over the coming periods.

• Maintained positive operating profit alongside increased investment in accelerating development programs in our lines of business: Advanced Batteries, Water, CO2 Mitigation, Biotech and Sustainable Processing.

• The Calix advanced batteries development program was accelerated following continued very positive results, and a clear investment case to insource critical battery and laboratory equipment.

• Backed by $39 million Australian Government funding package, Calix is partnering in Heavy Industry Low carbon Transition Cooperative Research Centre (HILT CRC) which aims to reduce carbon emissions of Australian heavy industrial processes.

• Awarded the maximum $1m grant under the Australian Government Manufacturing Modernisation Fund (MMF) to develop and transform its Biotech manufacturing capability at its Bacchus Marsh facility in Victoria

• Strong financial position with a closing cash balance of $15.1m, virtually zero debt and with $8 million in grant receivables due over the next 3 months to execute further R&D.


Commenting on the year, Calix's Managing Director and CEO, Phil Hodgson said:

We look back on FY21 as a year of continued achievement for the company across all our lines of business, under a remarkably and rapidly developing backdrop of the mainstreaming of ESG (Environment, Social and Governance) themes as central to investment and business strategies.

These investment and strategic themes are likely to prevail for many years to come. Our lines of business .... water, CO2 mitigation, sustainable processing, advanced batteries and biotech .... are all borne of the same core technology platform, and all stand to benefit from the massive interest in more sustainable solutions to global challenges.
