OREAS 255c
Артикул: 255c
OREAS 255c was prepared from a blend of gold-bearing oxide ore and barren
materials (basaltic scoria, quartz and mudstone). The oxide ore (Wilber Lode)
was sourced from the Andy Well Gold Project located approximately 45km north of
Meekatharra in the Murchison region of Western Australia. The Wilber Lode is a
shear- hosted, narrow vein, quartz lode-style gold deposit situated within the
Meekatharra-Wydgee greenstone belt in the Archaean Yilgarn Craton of Western
Australia. The Wilber Lode contains a common primary mineral assemblage of
quartz, calcite, chlorite, fuchsite, pyrite, galena, sphalerite, chalcopyrite
and gold. The host rock consists of a complex sequence of weathered Archaean
meta-basalt and meta-porphyritic rocks derived from a primary mineralogy of
albite, actinolite, chlorite, sericite, biotite, calcite, zoisite, muscovite,
quartz and titanate. Thirty-three commercial analytical laboratories
participated in the program to certify:
Gold by fire assay;
Gold by 15-50g aqua regia digestion;
Gold by 5-200g cyanide leach;
Gold by PhotonAssay with recommended gross mass 455±15g;
Full ICP-OES and ICP-MS elemental suites by 4-acid digestion;
Full ICP-OES and ICP-MS elemental suites by aqua regia
digestion.
