Deposit type

  • Porphyry

Summary:

Gold mineralization at Sukari is hosted exclusively by porphyry. The lack of significant gold grades in chemically reactive serpentinitic wall rocks can be explained in one of two ways:

• The porphyry represented a favourable host either because of its composition, relative to mineralising fluids, or its mechanical properties or both.

• The Sukari Porphyry was relocated, relative to wall rock sequences, by faulting after gold mineralization.

While significant post-mineralization faulting has possibly occurred, the second scenario is unlikely. Porphyry dykes in the hangingwall of the main porphyry body show gold mineralization of essentially the same character as that in the main porphyry and wall rocks immediately adjacent to those dykes are also barren. Those dykes range in thickness from a few centimetres to several metres. It is not reasonable to postulate that they, along with the main porphyry body, were all relocated by faulting after mineralization.

Certainly it is evident that the Sukari Porphyry has acted as a rigid body surrounded by weaker rocks. Footwall and hangingwall rocks have taken up strain by development of strong schistosity, almost certainly accompanied by large decreases in volume. The porphyry has taken up strain by development of predominantly brittle fault structures.

The porphyry host for the mineralization has a strike length of approximately 2,300 m, and ranges in thickness from 100 m to approximately 600 m (Cavaney 2005). Gold mineralization within this is not continuous and its deposition has been influenced by major long-lived structures, the most important of which are tabular sheets of crackle breccia.
