Mineral Mapping provides expert geochemical solutions to mining companies and the resources industry.
Over the last 40 years the standard commercially available geochemical assay techniques have changed from AAS to INAA to ICP-AES to ICP-MS.
The real cost per assay has barely changed, but we can now have 40 or more elements routinely assayed with detection limits way lower than average crustal abundance levels.
If you don’t analyse to these levels, then you can’t measure the full size of the anomaly. In addition to measuring ore metals and pathfinders, the immobile elements in the assay package allow a geochemical fingerprinting of the host rocks, and the major elements allow a quantification of the alteration mineralogy [...
