GR461 EL 25566, EL 27912, EL 27913, EL 31383 Second Annual Technical Report

Abstract

The 203 station ground gravitational data collected during 2017 over the centrally located 4 km x 4 km spaced, West Amadeus survey, regional Bouguer anomaly within EL 25566 was reviewed reprocessed and modelled by Geophysical Consultant to assess the depth of regolith over previously interpreted potentially Cu-Ni-Co mineralised 1078Ma Giles Complex occurring over 10 km of west to east strike for Claude Hills-type nickel-cobalt mineralised ochres ie analogues of MLX Claude Hills Ni-Co laterite deposit butting up to NT border 30 km to the south. During the above review a discrete circular regional Bouguer high was delineated 10 km east of current project area potentially representing more Cu-Ni-Co mineralised Giles Complex underlying Alkata North prospect area. Within EL 31383 there is a magnetically interpreted belt of 1080Ma Giles Complex whose nickeliferous ochre regolith potential was fleetingly tested by 4 drill holes during 1966 one of which namely NC 20 intersected 46.6m of ochre averaging 0.58% Ni and 800ppm Co while another, NC 22 ended in pyroxenite assaying 0.29%Ni thus indicating the potential for more Cu-Ni-Co mineralised Giles Complex north of the border consequently a 682 station first pass 500m x 500m spaced ground gravity survey was undertaken followed up by several areas of 250m x 250m spaced infill conducted over 1) ground gravity highs possibly indicative of primary sulphide-hosting Giles Complex and 2) ground gravity lows possibly indicative of secondary Ni-Co enriched regolith. The gravity lows will be RAB/RC drill tested while likely gravity highs will be Ground EM geophysically surveyed for a potentially mineralised enhanced conductive responsed.
