Magnesite
specimen number:
2354281
location:
Kurnalpi, Kalgoorlie-Boulder Shire, Western Australia, Australia
description: The Kurnalpi district, located within the Kalgoorlie-Boulder Shire of Western Australia, sits on the Archaean Kurnalpi Terrane of the Yilgarn Craton, a region dominated by metamorphosed volcanic greenstone belts, felsic intrusions, and major shear zones. Gold was first discovered at Kurnalpi in late 1894 during the eastern goldfields rush, sparking rapid prospecting that produced impressive coarse gold nuggets and rich surface alluvial workings. Historical underground mining was carried out through small shafts along quartz veins, but production slowed as shallow oxide reserves were depleted. In modern times, the locality remains a famous destination for metal-detecting enthusiasts and mineral collectors seeking iconic Australian gold nuggets and classic shear-hosted gold occurrences preserved within weathered greenstone host rocks.
Rich light green masses of nickel bearing magnesite with little matrix.
