Calix, via its wholly owned subsidiary Magnesium Developments Pty Ltd, owns and operates two mining tenements at Myrtle Springs, located in the Leigh Creek area, South Australia. These give the company the benefit of long term access to high grade* magnesite minerals.
A JORC - compliant resource estimate was carried out in April 2014, with a total of over 1.3 MT of magnesite identified across the various JORC categories (Proved Ore Reserve 370 kT, Probable Ore Reserve 65 kT, Indicated and Inferred Resource 909 kT)*. The deposit is expected to supply high grade minerals for production at Bacchus Marsh over the next ten to fifteen years.
Calix uses the minerals from the Myrtle Springs mine to produce Calix's range of magnesium-based products.

The six-hectare Bacchus Marsh site showcases our world-first technology, and was established in early 2010 and has grown to include a small-scale pilot Calix Flash Calciner “CFC” for materials testing, a fully equipped R&D facility for investigating new materials and quality control, and our commercial-scale CFC including feed bunkers, crushing and grinding circuits, feed mixing and pre-heating, processing, product storage and handling, and a Magnesium Hydroxide Liquid production and storage facility.
With a nameplate capacity of 30,000 tonnes per year of Magnesium Oxide production, our Bacchus Marsh facility has significant capacity to meet local and overseas market expansion.
Calix’s product development, production and supply were ISO9001 accredited in 2015, and were upgraded to ISO2001–2105 in June, 2017.
Calix’s advanced Magnesium Hydroxide Liquid (MHL) production plant on the Gold Coast was successfully commissioned in late December 2014. The plant has a capacity of 6,000 tonnes per annum per operating shift and can easily scale to grow with our customers’ needs. Using Calix’s unique, high reactivity Magnesium Oxide (MgO) powder as a feed source, the plant is capable of producing a batch of 60% solids MHL in less than 90 minutes, a world first. The plant is currently servicing all of Calix’s Queensland and northern New South Wales customers with plenty of additional capacity available for further growth, and was built with the kind assistance of a Commercialisation Australia grant.
The company has also established a hydration plant via our Joint Venture Partners in the Philippines – ACTI-Mag Asia Inc. - and intends to keep building and operating these hydrating facilities worldwide. Calix also has an established UK office developing our business and projects in Europe.
