Abstract
Weathered samples from naturally exposed outcrops of troctolite associated with a magmatic
Ni-Cu sulphide deposit were characterized by synchrotron-based micro-X-ray fluorescence mapping
(µ-XRF) and X-ray absorption spectroscopy (XAS), as well as by lab-based X-ray diffraction, electron
microscopy, Raman spectroscopy and wet chemical methods. Metal mobility in weathered samples
was assessed using a sequential leach procedure. Results are interpreted in the context of predictions
for future mine water chemistry and used to refine the conceptual model for metal mobility following
weathering of waste rock at a potential future mine site.
