| Description: OREAS 609b 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: - Au by fire assay with AAS or ICP finish
- Au by aqua regia digestion with AAS or ICP finish
- Full ICP-OES and MS elemental suites by 4-acid digestion
- Full ICP-OES and MS elemental suites by aqua regia digestion
- Total S by Infrared combustion furnace
Indicative values for Sulphate Sulphur and Sulphide Sulphur (among others) are also available. Download Certificate OREAS609b Download DataPack OREAS609b | Analyte | Certified Value | 1SD | 95% CI Low | 95% CI High | Method |
