The extinct Haveri Au-Cu deposit is located within mafic metalavas and mafic/ intermediate banded biomat for sale rocks of the Haveri Formation, in the western part of the Paleoproterozoic Tampere Schist Belt.The sulfide-bearing banded rocks display a large E-W trending fold structure in magnetic and electromagnetic maps.Field evidence suggest that the Au-Cu deposit is in a F1/F2 fold interferrence pattern in the western core of the large fold.
The ore-forming elements concentrated into the F1 fold read more closure during D1 deformation.Sulfide-bearing fractures subparallel to S2 spaced cleavage indicate slight remobilization during D1.
