URL: https://geoscience.data.qld.gov.au/dataset/cr125339 The Geological Survey of Queensland (GSQ) Reference Collection project is a physical and virtual collection of samples from the major deposits within the Mount Isa Province. This project was funded under the Queensland Government’s Strategic Resources Exploration Program (SREP) between 2017-2021. The Ernest Henry camp study data is located over an area 6 x 6km and is located ~35km NE of Cloncurry within the Eastern Succession of the Mount Isa Province. The main aim of the Ernest Henry camp scale study was to characterise the mineralisation and alteration signatures of the Ernest Henry deposit and larger Cu-Au mineralising system. This was done by collecting continuous mineralogical data (via our Hylogger-3 machine) and spot multi-element geochemistry across a total of 19 drill holes within and around Ernest Henry and along a north-east trend towards the FC4S Prospect. This report discusses data collection methods and preliminary observations on the alteration halo of the Ernest Henry deposit, as well as defining the geochemical signature of ore mineralisation.
