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.
Within the program area, uranium drill hole intercepts, as defined by down hole gamma logging
, showed a range of grades of up to 0.
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.
of Mendoza, Argentina will be responsible for the drilling program with an in-house technical group conducting the down-the-hole gamma logging
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.
also of Mendoza, to conduct the down-the-hole gamma logging
of the drill holes.
Confirmatory samples will also be collected and sent for assay from anomalous zones defined by the gamma logging
The Mineral Resource estimations are based on the use of a combination of analytical assays (XRF) and downhole gamma logging
results, following the application of standard practice radiometric calibration methods for U3O8.
Drilling commenced with four RC rigs on 19 May 2011, with immediate encouragement from chip logging and downhole gamma logging
returning high eU3O8 results.
Based on historical exploration information, including rotary drill and gamma logging
information, Uranerz believes that it now has total potential uranium resources in Wyoming of over 30 million pounds measured as U3O8.
A number of mineralised holes which also had high-grade downhole gamma logging
results are still in the process of being assayed.
