This I think is the report

THUNDELARRA LIMITED MARCH 2015 QUARTERLY REPORT

Audio Magneto-Telluric (“AMT”) Survey

Several AMT traverses were carried out over parts of Curara Well and Red Bore during the Quarter. The data were still being processed and interpreted at the end of the Quarter.

AMT is a broad scale geophysical technique that uses the natural charge in the ground - in layman’s terms, the “left-overs” from lightning strikes – to measure the contrast between areas of higher and lower conductivity and resisitivity: boundaries or zones between rocks that are better or worse conductors of electrical charge. The information from such surveys can assist in identifying the location and orientation of deep-seated structures (for example, the Jenkin Fault Zone), and we are hopeful that it can assist in our interpretation of the distribution of and relation between of the different rock types at Red Bore and Curara Well.

As with the aeromagnetic data, the processed data from the AMT surveys will be incorporated into our conceptual mineralisation model to aid future drillhole targeting.

There is other references about other magnetic surveys in March 2015 Quarterly Report. THX must have seen something in this drilling program to warrent another look at this survey data.
