At the Batu Mas Prospect, which means 'Gold Rock' in Bahasa Indonesia, one of Robust’s key targets, the Company has drilled 67 holes for 9,300 metres at July 2011 with a Strike length over 350m and open in all directions. The thick zone of gold and silver mineralisation discovered by Robust at Batu Mas starts at or near surface and a zone abundant with base metal sulphides has also being discovered beneath it.

It is Robust’s belief that Batu Mas demonstrates the potential to host a world-class discovery.

Robust currently has two owner operated rigs working on site at Batu Mas and recent drill results have encountered precious metal mineralisation of potentially economic grades and widths significantly extending the identified zones of near-surface high-grade gold-silver mineralisation. These results have confirmed Robust’s beliefs that Batu Mas is demonstrating the potential to host a world-class gold discovery.

IP RESISTIVITY STUDY

Results from the recent 3D IP Resistivity survey carried out over the Lakuwahi project have confirmed previous drilling results in that a large geophysical anomaly exists of gold-silver with an underlying zone of significant base metals. More importantly, the Resistivity Survey has demonstrated that the geophysical anomaly clearly links the Batu Mas and Batu Hitam Prospects. Given the positive results, Robust is now confident to move towards defining a maiden JORC resource from these two prospects alone.
