Nizzaite is a mineral formed by the release of metal vapor excreted by lithotrophic microbes consuming local detritum through their natural digestive processes. It has an average metal content of 51%.
Nizzaite is discernible by its towering, stalagmite-like appearance, emerging from the ground in large spikes that rival the height of trees in some instances. As they are produced by thousands and even millions of years by microbes, they are actually biologically active, although these levels of organic material are in such trace amounts it is not worth harvesting. It is a dark yet faint purple in hue.
