  • Identifying Pathfinder Elements for Gold in Multi-Element

    The objectives of the study were to define gold relationships with other trace elements to determine possible pathfinder elements for gold from the soil geochemical data The study focused on seven elements, namely, Au, Fe, Pb, Mn, Ag, As and Cu Factor analysis and hierarchical cluster analysis were performed on the analyzed sampl.

  • Critical elements in Carlin, epithermal, and orogenic gold

    Carlin, epithermal, and orogenic gold deposits, today mined almost exclusively for their gold content, have similar suites of anomalous trace elements that reflect similar low-salinity ore fluids and thermal conditions of metal transport and deposition Many of these trace elements are commonly referred to as critical or near-critical elements or metals and have been locally recovered.
