Robust finds widest gold, silver zone in 10-month drilling campaign

Australian mining firm Robust Resources Limited said on Tuesday that it has intercepted a 52 meters wide zone of gold and silver breccia assaying 1.57 g/t Au Equivalent (1.12 g/t Au and 27g/t Ag) at its Batu Hitam prospect in the Lakuwahi Caldera gold, silver and base metal project, Romang Island, East Nusa Tenggara

The intercepted deposit is located at LWD 042 in the upper part of the hole, which is on the north-eastern extremity of Batu Hitam, where consistently higher gold grades have been encountered than in any previous hole. This indicates possible a closer proximity to exhalative source structures or vents, the company said.

The zone includes 18 meters at 2.13 g/t Au equivalent.

?This is the widest zone of gold and silver identified by Robust in its 10-month drilling campaign at Romang Island?s Lakuwahi Caldera Project,? it said.

According to the company, underlying and partially overlapping the gold zone is a zinc-lead-silver-rich breccia, which is one of the strongest-yet intersected in Batu Hitam.

Since Robust began its Romang Island drilling program in November 2008, the company has received assay results from 28 diamond drill holes, of which 27 have identified reportable intersections of gold/silver/lead/zinc/copper having potential economic significance.

Drilling is continuing at the Batu Mas and Batu Hitam prospects and is about to begin on the Batu Jagung prospect in the Lakuwahi Caldera Project; which encompasses the southern one third of Romang Island. Work is underway to identify drilling targets at the Solat Caldera, which forms the northern two thirds of Romang Island, where exploration has revealed strong evidence for the existence of at least one gold- rich multi-commodity porphyry system, it added.
