The Errabiddy tenement covers an area with potential for Th concentrations in the regolith or in undiscovered carbonatites.

Errabiddy Exploration Licence 52/1962, was applied for by Geotech International on 17th May 2006 and was granted on 11th January 2007. The geology in the Errabiddy exploration licence is very similar to that found on Bullbadger.

Similarly to Bullbadger, previous work on and around this tenement mainly comprises Government Geological Surveys; Government Geophysical Surveys; Government Geochemical Surveys; CSIRO Geochemical Surveys. Private exploration work was also carried out by the Ferrovanadium Corp NL; Newmont, Peregrine Resources; Helix Resources; an independent geologist, Peter Woods; Astro Mining; Hampton Hill Mining NL; and by Normandy Yandal Operations.

The area has had two periods of exploration that have involved collecting alluvium from drainages. The first sampling involved the collection of two large samples of creek alluvium. Then, late in 2007, a further, more numerous and widely spaced, suite of large samples of creek alluvium was collected at 26 sites. At the time of writing the CPR the sample results were unavailable. In addition numerous rock samples were collected.

Finally, several traverses were completed with an auger rig allowing the collection of 77 samples down to a maximum depth of 1.8 metres. Each sample was scanned with a scintillometer and total counts recorded.

Sample EBA052 which was a sandy alluvium from a creek recorded the highest REE analysis as recorded in Table 1.

Other samples recorded elevated REE analyses. The presence of a widespread Th anomaly associated with the presence of REEs on this tenement makes it of interest.
