EL 28886 Annual Technical Report 4 Delmore Downs

Abstract

Detailed analysis of 2010 Sandover SKYTEM /AMAG 500m l.s. heliborne located, digital geophysical survey data was undertaken by Consultant Geophysicist to further refine existing potential RAB/RC drill targets over relatively shallow sub surface conductor areas 1, 2 and 3 deliniated during 2013-14 program. However prospecting the areas overlying sub surface conductors revealed extensive exposures of flat lying Tertiary Waite Fm chalcedonic limestone ranging from zero-150m thickness, often known to possess sizable acquifers of fresh water that respond to AEM surveying conductively thus requiring a recalibration of postulated depths of conductors 1, 2 and 3 by applying advanced computational modelling of depth to magnetic basement techniques to ensure above conductive responses are indeed basement-hosted ie coincident with discrete elevated AMAG features possibly indicative of economic IOCGU sulfide mineralisation. A follow up program of close spaced AEM/Helimag geophysical surveying is proposed if depth to magnetic basement cannot be resolved satisfactorily (over Conductors 1 , 2 and 3 using available AEM/AMAG data) followed by RAB/RC sub surface drill testing of anomalies deliniated if warranted.
