Structure – Key to Ore Formation






       •   Structural control important for                                                       Fault architecture set up by Atacama Fault System – NW splays
           channelling fluid and providing
           dilation within host rocks for                                                                                                                    AFS
           ore formation.


       •   Master fault zones control
           location of conjugate NW fault
           sets and associated sheeted
           vein systems within the
           intrusive hosts.


       •   Possibly shared structural
           controls with adjacent IOCGs                                                                                       NW SPLAYS
