EL 28837 Pulpit Rock Annual technical report 5, 14 March 2016 to 13 March 2017

Abstract

A 5th year program comprising acquisition, image processing integration with suitably enhanced TMI and radiometrics of latest LANDSAT spectral emission and SRTM digital data was carried out along with several different AEM Inversion schemes to more accurately model 3D subsurface conductivity thus helping resolve apparent depth conundrums of Palaeoproterozoic basement-hosted discrete AEM conductors potentially indicative of IOCGU-type massive sulphide-hosted mineralisation brought about by waxing and waning fresh water deposition of ubiquitous unconformably, flat-lying Tertiary Waite Formation chalcedonic limestones whose drill indicated thickness over southern part of Area 3 is at least 130m (vertical depth) also containing albeit mostly near-surface highly conductive aquifers of potable water which until now are more or less indistinguishable from those deemed basement-hosted conductors? Close-spaced AEM/Helimag geophysical surveying over Areas 1, 2 and 3 is recommended (further refining 5 pre-existing basement-hosted conductors delineated by 2002 and 2007 AEM geophysical surveying) followed up by fences of RAB/RC subsurface drill testing if warranted.
