MultiMiner at Goldschmidt 2025: Advancing Knowledge on Magnesite Formation

A few weeks ago, at the Goldschmidt Conference in Prague, Ferdinand J. Hampl of Montanuniversität Leoben presented novel findings on magnesite from the Hochfilzen mining district, as part of the MultiMiner project. His presentation, delivered during the session “New advances in metallogenesis from magmatic-hydrothermal to basinal environments and their applications to exploration and metal recovery”, highlighted how state-of-the-art mineralogical techniques are transforming our understanding of magnesite deposits in the Eastern Alps.

Magnesite, a vital raw material for refractory magnesia, occurs in two distinctive geological settings at Hochfilzen. Ferdinand’s research demonstrates that both types, carbonate-hosted and breccia-hosted, share a common origin, as confirmed by advanced analytical methods including electron microprobe analysis, LA-ICP-MS, and Raman spectroscopy. These insights advance scientific understanding and help to guide future exploration strategies for critical raw materials.

This research forms part of MultiMiner’s broader mission to develop innovative tools for sustainable mineral exploration and monitoring, paving the way towards a safer and more environmentally responsible mining future for Europe.
