    Typical saprolite consists of a zone of intercalated structural limonite and grey/green to yellow/green saprolitic clay displaying fairly well-preserved remnant mineral structures of the underlying ultramafic. Normally in laterite deposits, the Ni content is concentrated in the saprolite zone, but there is little enrichment at Moa.
