AMIS's range Zinc CRMs
Zinc price has recently hit its highest level ever since 2007. This is the highest record in a decade. There are more than 50 countries that mine Zinc in the world.
Zinc is a blue-grey non-ferrous metallic commodity with very high anti-corrosion properties, it commonly occurs together with lead mineral deposits. Zinc ores are commonly hosted in sulphide mineral called sphalerite. Sphalerite provides almost 90% of the zinc produced in the world, with the remaining 10% produced from 5 other minerals; smithsonite, zincite, zincosite, willemite, and franklinite.
Zinc (Zn) and lead (Pb) are commonly deposited together, in ore deposits that are formed under low-temperature hydrothermal fluids. There are several types of Pb-Zn ore deposit, but SEDEX (sedimentary exhalative) and MVT (Mississippi Valey type) are the two most significant deposit types.
AMIS offers a range of Zn CRMs from both sulphide and oxide deposits. Our Zn CRMs range from low to high grade. These CRMs are all matrix matched and will improve all your analytical analysis.

AMIS0516 PGM 4E 4.14g/t UG2 West Limb ZA
Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within an iron oxide matrix.
IOCG deposits are characterised by the presence of Cu with/without gold hosted in a hematite-matrix (iron oxide matrix). Hydrothermal fluids in a volcanic setting are responsible for the mineralisation of these deposits. The breccias and veins were formed by a repetitive hydrothermal brecciation and venting with the volcanic setting. As a result the host sequence rocks are intensely altered by hematite-sericite-chlorite-carbonate. The breccia’s are extremely iron rich and themselves comprise a huge iron resource made up of hematite and minor magnetite. The fluids contain dissolving salts capable of dissolving small amounts of Au, Ag, Cu, Fe and variety of rare earth elements (REE) minerals. Mineralisation of these deposits is found in hydrothermal veins and breccia.
Prominent Hill, together with Carrapateena, Olympic Dam, Moonta-Wallaroo and Hillside, are all IOCG mineralised systems.
AMIS has a wide range of CRMs that are certified for all of the economic elements mined at Prominent Hill (Fe, Au, Cu, Mn and Co).
