OREAS
609c was prepared from a blend of gold-copper-silver bearing ores from Evolution
Mining’s Mount Carlton Operation in Queensland, Australia and barren rhyodacite
rock sourced from a quarry east of Melbourne, Australia. A small amount of
copper-gold-silver rich materials sourced from various ores/concentrates was
also added to help achieve the desired grades.
The
mineralisation assemblage at Mount Carlton consists of pyrite,
enargite/tennantite, tetrahedrite, digenite, covellite, sphalerite, galena,
alunite, dickite, kaolinite and vuggy silica, hosted in argillic altered
rhyodacite containing sulphur-salts.
The
certification program includes:
Analyte | Indicative Value | 1SD | Expanded Uncertainty Low | Expanded Uncertainty High | Method |
---|---|---|---|---|---|
Au, Gold (ppm) | 4.75 | TBD | TBD | TBD | Pb Fire Assay |
Cu, Copper (wt.%) | 0.475 | TBD | TBD | TBD | 4-Acid Digestion |
Ag, Silver (ppm) | 24.1 | TBD | TBD | TBD | 4-Acid Digestion |
S, Sulphur (wt.%) | 1.57 | TBD | TBD | TBD | 4-Acid Digestion |
