Petermann Project Combined Annual Technical Report GR461 period from 28 August 2016 to 27 August 2017

Abstract

A regionally elevated gravity feature located centrally within EL 25566 was followed up by a 203 station ground gravity survey defining 4 semicircular gravity anomalies over 10 km of strike length. The anomalous ground gravity features were followed up by the Area 1 400 line km VTEM/Helimag geophysical survey comprising 32 N-S flight lines 500m apart delineating an east-west trending linear zone of sub surface conductivity 12 km long by 2 km wide. Within EL 31383 there is an interpreted belt of 1080Ma Giles Complex ultramafic rocks located between south of Mann Fault and SA border occurring over a strike length of 25 km. The perceived Cu-Ni-Co-Cr-Au massive sulphide-hosted potential of this belt of highly prospective rocks was tested by the Area 2, 291 line km VTEM/Helimag geophysical survey comprising 69 NS flight lines 500m apart delineating several discrete conductors along the length of the Mann Fault. More ongoing Inversion Modelling of above sub surface conductivity is required to generate first order drill targets consequently expenditure for forthcoming licence year of GR461 is set at $135,500.00.
