Type C deposits are covered by a veneer of residuum. Although the
probability of finding this deposit by direct observation is greatly
reduced, the release of metals during chemical weathering can lead
to dispersion of mineralization elements in the residuum. Soil geochemical
surveys here are effective to find this kind of ore deposit. The
weathering products of type A, B and C are easily transported into drainage
systems and will give rise to a detectable anomaly. Thus there is also
an excellent chance of discovering these deposits with regional reconnaissance
