The lateral and vertical distributions of gold and a wide range of
other elements in the regolith, close to Au and Cu mineralisation
have been investigated at Goonumbla, NSW. Open cut mining
has exposed deeply weathered profiles which have been used for
this investigation. Determination of secondary mineralogy and micromorphology
of profiles have facilitated the broad interpretation of processes
that determine element mobility and dispersion from primary
mineralisation as a result of weathering. This in turn has led to
better interpretation of geochemical data and enhanced
understanding and knowledge of regolith geochemical processes
which are invaluable in the formulation of improved exploration
Procedures.
