Are you one of those companies that assays a multielement geochemical suite with 40 or more elements, then then only ever looks at the assays for ore metals? All of the elements in the multielement packages contain information about the nature of the host rock, the alteration mineralogy and the pathfinder element haloes, as well as the distribution of the ore metals.
With the experience of having worked on literally thousands of these data sets, Mineral Mapping has developed a systematic approach to characterizing the host rocks from the immobile trace element signatures, mapping alteration vectors by designing major element scatterplots based on the stoichiometry of the alteration minerals, mapping sulphide mineral speciation from binary and ternary scatterplots, and then looking at the chemical and spatial controls on pathfinder element patterns and alteration mineralogy. Determination of the silicate mineralogy using a SWIR instrument adds another layer of constraint to the geochemical interpretation. Data sets with tens of thousands of analyses can be interpreted and modelled using software packages like ioGAS and Leapfrog. The aim is to be able to predict ore body geometry and clearly define geochemical criteria that will identify a “near-miss” drill hole.
