Robust Resources intersects significant polymetallic gold-base metal zone on Romang Island

Indonesian-based gold and base metal explorer Robust Resources (ASX: ROL)  has revealed the assay results for a further three diamond drill holes at its Lakuwahi Caldera Project on Romang Island.

Significantly, at the Batu Mas Prospect, where world-class gold grades were reported in December 2009, a large zone of highly encouraging base metal mineralisation was intersected below the near surface gold intersections in hole LWD 055.

Highlights from final assay results received from hole LWD 055 include 21 metres at 2.92 g/t Au equivalent (2.37 g/t Au and 33 g/t Ag) from 2 metres, including 10 metres at 4.74 g/t Au equivalent (4.47 g/t Au and 16 g/t Ag) from 2 metres 83 metres at 2.7% combined Cu+Pb+Zn from 28 metres, including 28 metres at 5.3% combined Cu+Pb+Zn from 70 metres.

Hole LWD 055 is located in the most north-eastern area of the Batu Mas Prospect and has increased the overall strike length of the mineralisation to over 300 metres, with both the near surface precious metal zones and the underlying base metal zones open in at least three directions.

Robust now has two diamond drill rigs on site at the Batu Mas Prospect dedicated to further extending the defined mineralisation. A third rig continues to explore Batu Hitam and a fourth rig is scheduled to be commissioned in March 2010.

Managing Director Gary Lewis said with each new set of Batu Mas assay results, the company continued to intersect significant grades, further strengthening the Board’s belief that it was potentially sitting on a major new gold and base metal discovery.

"With mineralisation remaining open in three directions, we are keen to progress our exploration program as soon as possible, with the fourth rig expected in March, so that we can continue to identify the scale of this exciting discovery," Mr Lewis said.

Additionally, Robust announces final assay results from drilling at the Batu Hitam prospect, located 1.5 kilometres to the east-south-east of Batu Mas, in the Lakuwahi Caldera Project.

Highlights include LWD 056: 29 metres at 1.11 g/t Au equivalent (0.75 g/t Au and 22 g/t Ag) from 8 metres, including 11 metres at 1.46 g/t Au equivalent (1.11 g/t Au and 26 g/t Ag) and 2 metres at 4.9% combined Cu + Pb + Zn from 5 metres.

At this point in time at Batu Hitam, the Company intends to concentrate on following-up the excellent intersection in drillhole LWD 042 of 52 metres at 1.57 g/t Au equivalent and 36 metres at 3.0% combined Cu+Pb+Zn including 10 metres at 4.6% combined Cu+Pb+Zn.
