Batu Jagung translates as “Corn Rocks” in reference to the mineralised outcrops discovered in local famers’ corn fields
Robust has completed initial drill testing of the new Batu Jagung base metal prospect in the northern area of the Lakuwahi Project. Encouraging drill results such as those in hole LWD057 below have lead to an enlarged drill program which is planned to begin before the end of 2011.

Results from hole LWD 057 included:

27 metres at 74 g/t Ag from 4 metres
and 75 metres at 2.0% combined Cu+Pb+Zn from 56 metres

These are highly encouraging first pass drill results in this new prospect, however Robust has suspended drilling in this area for the present time, so that an additional drill rig can be utilised on site at Batu Mas to follow up the significant precious metal mineralisation recently identified. Robust is continuing with detailed geological mapping of this area, which will be used in conjunction with the planned 3D Induced Polarisation (‘IP’) survey, with the aim of delineating further base metal targets at Batu Jagung.

Notes:
The information in this announcement that relates to Exploration Results, Mineral Resources or Ore Reserves was compiled by John Levings BSc, who is a Member of The Australasian Institute of Mining and Metallurgy and who has more than ten years experience in the field of activity being reported on. Mr Levings is a director of the Company. Mr Levings has sufficient experience, which is relevant to the style of mineralisation and type of deposit under consideration and to the activity, which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Mr Levings consents to the inclusion in the announcement of the matters based on his information in the form and context in which it appears. 1 All thicknesses are down-hole drilled thicknesses. 2 Au Equivalent (Gold Equivalent) = gold assay + (silver assay / 60) where the number 60 represents the ratio where 60 g/t Ag = 1g/t Au. This ratio was calculated from the fifteen year average prices of gold and silver prices from January 1995 to 30 December 2010 World Bank Commodity Price Data (average Gold price is USD $515.98 per Troy Ounce and average Silver price is USD $8.58 per Troy Ounce). Metallurgical test results previously reported have indicated high extraction rates (94%-95%) for both gold and silver using standard technology. 3 Cu Equivalent (Copper Equivalent) = [(copper assay x copper price x 22.05) + (gold assay x gold price/31.1) + (silver assay x silver price/31.1) + (zinc assay x zinc price x 22.05) + (lead assay x lead price x 22.05)] / (copper price x 22.05). The metal prices used in this copper equivalent calculation were taken from the average of the 12 months from January to December 2010 taken from published World Bank Commodity Price Data. The metal prices thus used in the calculation are: Copper: USD $3.42 per pound, gold: USD $1,224.66 per Troy ounce, silver USD $20.20 per Troy ounce, Lead USD $0.9745 per pound and Zinc USD $0.9801 per pound. Preliminary metallurgical test results previously reported (30th November 2010) indicate high and broadly equivalent flotation recoveries for all metals used in the copper equivalent calculation (gold recoveries average 84.3%, silver 93.0%, zinc 97.2%, lead 91.1% and copper 94.6%).
