Lithocaps are potentially voluminous zones of advanced argillic and associated argillic alteration located above the
subvolcanic intrusive environment. They constitute exploration objectives for epithermal and porphyry-type deposits.
High-sulphidation epithermal deposits may be sought within lithocaps, whereas low-sulphidation deposits may exist on
their edges. Porphyry Cu-Au/Au deposits may be accessible beneath lithocaps if systems are telescoped sufficiently.
Oxidation of the basal, pyritic parts of lithocaps may promote supergene sulphide enrichment under appropriate tectonic
and climatic conditions.
