OREAS 600c
SKU: 600c
OREAS 600c was prepared from a blend of gold-copper-silver ores from various
Australian ore deposits and argillic rhyodacite sourced from a quarry east of
Melbourne, Australia. The mineralisation assemblage consists of pyrite,
chalcopyrite, electrum, enargite/tennantite, tetrahedrite, digenite, covellite,
sphalerite, galena, alunite, dickite, kaolinite and vuggy silica, hosted in
advanced argillic altered rhyodacite containing sulphur-salts.
