Great Boulder Resources announced that it has significantly enhanced the exploration potential of its Tarmoola gold project, 40km north-west of Leonora and 10km west of Saracen's King of the Hills gold mine, after receiving highly encouraging results from a recently completed auger geochemistry programme. The detailed geochemistry programme has confirmed and defined the same anomalous trend from the regional data, while also identifying several new anomalies along the interpreted granite-greenstone contact and other structural trends. A total of 983 auger samples were taken covering 149km2 (14.4Ha) of the Tarmoola project, testing for gold and pathfinder soil anomalies that would indicate the presence of a gold bearing hydrothermal system. The gold and pathfinder assemblage is consistent with intrusion related gold deposits and shows similarities to Saracen's neighboring King of the Hills and Thunderbox mines, where gold-pyrite mineralisation typically occurs around the margins of the intrusions. In the soil profile, pyrite is unstable and oxidizes which dissolves and removes Sulphur, however many trace (pathfinder) elements do not dissolve and remain in the soil. In similar intrusion-related gold systems, the trace elements in the pyrite are typically Bi and Te, +/- Mo and often zoned with As occurring a little further from the intrusion. Therefore in the soils, the company can use these metals as a proxy for gold-bearing ore-stage pyrite. The results of the auger geochemistry show strong and coincident gold-arsenic-bismuth-tellurium anomalies with silver also along the contact margin over several kilometres. In order to better understand the significance of these geochemical anomalies, Great Boulder has re-processed 100m flight line airborne magnetic data over Tarmoola and the surrounding area and deposits, combined with field mapping and previous drilling data to produce an updated geological and structural model.
