News Issue December 2022

Welcome to Issue Number 43 of the Calix Newsletter.

“The last quarter of the calendar year has been just as busy as the first three !

We continued our investment in new talent, with 14 new staff members featured in the newsletter, including our new Chief Technology Officer, Dr Louise Keyte. I am sure that as you read our new teams’ backgrounds, you will be impressed with the depth and breadth of talent that Calix continues to attract. Our people are our most important asset, and we have grown the team considerably over the last 6 months. They are the future of this company and we welcome them to the team !

Also featured in this newsletter is the now formal Joint Venture arrangements with Pilbara Minerals Limited (ASX:PLS) to develop a low carbon lithium salt demonstration facility using Calix’s unique electric kiln technology. The agreement is the culmination of many months of hard work, in parallel with the great engineering and test work being undertaken to develop the project to a final investment decision for a 3,000 tonne per annum facility targeting June, 2023. Both Calix and Pilbara Minerals see huge opportunity in the supply of low carbon lithium salt from Australia, and look forward to working together to capitalise on this significant opportunity.

Our technology and its application to cement and lime decarbonisation – “Leilac” – is also featured in this newsletter, with a feature on our first-of-a-kind global, perpetual licence deal with Heidelberg Materials, our new developments into clay / clinker substitutes, CALIPSO, and the development of three Leilac projects with Cemex. The Heidelberg Materials licence deal is of significance, in that it is the first time our royalty-based business model has been validated, with one of the world’s premier cement companies. In addition, three projects covering Europe and US, and a second global licence agreement (currently under negotiation) are being developed with Cemex, another of the world’s premier cement companies. And we are continuing our development of additional solutions for the cement industry, with our CALIPSO application of our core technology to produce calcined clays, which can partially substitute traditional clinker at lower carbon footprint.

Also featured in this newsletter is our ZESTY zero emissions steel technology – one our latest applications of the core technology into the decarbonisation of iron and steel. With positive results during 2022 in converting iron ore to iron, using hydrogen instead of coal, as well as the recent award of a ~$1m ARENA grant to help cover the front-end-engineering and design costs of a demonstrator scale ZESTY plant, we are further encouraged to develop ZESTY as quickly as possible, and will be planning new test runs in our converted pilot facility in early 2023.

As 2022 draws to a close, it is also timely to look back upon another great year for the company, in our mission to solve global challenges, and in particular on our sustainability performance. Calix has released our second sustainability report – the United Nations Global Compact Communication on Progress (“COP”). This newsletter features a summary of our latest COP report, which will also be available in full via a link.

Lastly, the Calix team would like to thank all our shareholders and stakeholders for you continued support through a tumultuous 2022. The company’s considerable achievements, with your support, have been that much more remarkable given global volatility. We look forward to 2023 and advancing rapidly on multiple opportunities, and in the mean time wish you, your families and friends a safe and enjoyable Christmas and New Year.”
