Welcome to Issue Number 44 of the Calix Newsletter.

“The year has leapt ahead and the pace of development of the business and opportunities is quickening. In the newsletter, we feature several articles on recent policy moves both in Australia and abroad, which serve to strengthen tailwinds for our technology in industrial decarbonisation. Calix has made submissions to the Australian Government on its Safeguard Mechanism and Critical Minerals Strategy – both important initiatives that are starting to galvanise action amidst improving clarity on Australia’s position in decarbonisation. This clarity is essential if Australia is to re-build and add value via an expanding domestic manufacturing and processing capability. Our lithium project with Pilbara Minerals and the development of our Zero Emissions Steel TechnologY (ZESTY) are just a couple of examples of the opportunities we see in Australia, and overseas.

In the newsletter, we outline several new opportunities and updates for our Leilac (Low Emissions Intensity Lime and Cement) business, with an MOU outlining a development with Bill Gates-backed Heirloom for Direct Air Capture (DAC), progress in our UK low emissions lime project with Tarmac, a grant announced from the UK Government to progress our partnership with Windship for zero emissions shipping, and an article on our recent announcement to progress a sustainable fuels solution based on methanol with an Australian-German consortium lead by Vast Solar, with Adbri.

We also feature a couple of articles on the “often-forgotten” development of the Calix technology into advanced materials such as for advanced batteries and biotech. We were pleased to execute formal arrangements with the CRC SAAFE research effort looking into solving anti-microbial resistance, using our unique, high activity and safe magnesium oxide. Next steps will involve setting up the project research streams, including potential veterinary applications. We also report on the latest news on our battery materials development program, with commercial production and testing of our Lithium Manganese Oxide cathode material with UK’s AMTE Power in full swing, and new chemistries exhibiting excellent early results such as our lithium iron phosphate cathode material.

Calix would not be where we are without our great team, and in this newsletter we celebrate some of the great women in our team as part of International Women’s Day. We also feature our new Non-Executive Director, Alison Deans, who recently joined the Calix Board in conjunction with the retirement of Dr Jack Hamilton, as part of our board renewal process. On behalf of the Chair, board and Calix team we extend our thanks to Jack for over 10 years of valuable advice and hard work over his tenure, and welcome Alison to the team.

As always, the Calix team extends its thanks to our shareholders and stakeholders for your ongoing support and interest in our efforts and we look forward to an exciting and fast-paced 2023!”
