Final technical report on Mount Ebenezer Gravity Survey for EL 26243

Abstract

This report describes the 2008 Mt Ebenezer gravity survey conducted under the Drilling and Geophysics Collaboration program, a component of the NTGS's 'Bringing Forward Discovery' initiative. A precision Gravity/GPS survey was carried out by Daishsat Geodetic Surveyors over EL 26243 Mt Ebenezer exploration licence held 100% by Quasar Resources Pty Ltd (QSR). A total of 1,544 gravity stations were collected at a nominal spacing of 1km. The survey was carried out between 12 and 17 of November 2008. Significant improvement in the gravity coverage of the area has been achieved from this survey. The existing sub-standard data only showed two broad gravity anomalies. Greater detail in the new data shows the nature of the east-west thrust and how it terminates against a north-west trending structure. The high gravity responses shown are related to intrabasinal fold and thrust structures of the Palaeozoic clastic succession of the Larapinta and Pertnjara group. The detail of these structures shown in this data is not seen in other datasets. This has highlighted new exploration targets as these features can now be are tracked from their outcropping positions under cover.
