tools were calibrated prior to the drilling program and verified by an independent 3rd party geophysicist.
Down-hole gamma logging
relies on detecting the daughter products of uranium, Bi214 and Pb214.
Several mineralized intercepts have been made on the Bella Rose Fault Zone at Bella Rose and Mt Osborne South, where assays are pending but gamma logging
has shown a number of significant anomalies.
The first field station included a geophysical demonstration by the Indiana Geological Survey of downhole gamma logging
(in a PVC cased well) and surface resistivity arrays.
The drilling will collect core samples of the potash horizons and is likely to confirm the presence of potash which has previously been detected by gamma logging
of petroleum wells.
Confirmatory samples will also be collected and sent for assay from anomalous zones defined by the gamma logging
Drilling commenced with four RC rigs on 19 May 2011, with immediate encouragement from chip logging and downhole gamma logging
returning high eU3O8 results.
A number of mineralised holes which also had high-grade downhole gamma logging
results are still in the process of being assayed.
