Partial relinquishment report EL 26287 Mount Denison 1 April 2008 to 31 May 2013

Abstract

This partial relinquishment report for EL 26287 covers work carried out by Toro Energy during tenure from 1 April 2008 to 31 May 2013. Fugro were commissioned to fly and AEM survey during August 2009. The survey was flown at 1000m spacing on EW flight paths. Aircore drilling was carried out in November 2010 by Wallis Drilling using a Delta10 drill rig. Holes were drilled to refusal through interpreted Tertiary sediments consisting of varying sand, silts and clays. The long narrow conductive feature in the western part of the area was found to be caused by saline groundwater infiltrating a clay-weathering zone developed along a major structure. Only limited sand was encountered and no anomalous gamma radiation was identified and this area is of no further interest.
