Romang Island continues to deliver for Robust Resources

THE DRILL SERGEANT: Robust Resources (ASX: ROL) has received assay results from five diamond drill holes from recent drilling at the Perak Basin VMS target, within the company’s Romang Island project in Indonesia.

According to Robust each hole intersected precious metals and base metals with the most encouraging results coming from drilling on the open western side of the Perak Basin.

Two holes, LWD 385 and LWD 390, were drilled in this area.

Results from LWD 385 included high-value VMS exhalative style mineralisation, returning:

7.4 metres at 4.58 grams per tonne gold equivalent and 2.99 per cent combined base metals from 12.6m (1.97g/t gold, 138g/t silver, 0.08 per cent copper, 2.9 per cent lead, 0.02 per cent zinc).

Located 80m south-east of LWD 385, LWD 390 intersected higher grades of:

7.2m at 14.1g/t gold equivalent and 5.56 per cent combined base metals from 18.8m (0.77g/t gold, 707g/t silver, 0.14 per cent copper, 3.11 per cent lead, 2.41 pe cent zinc);

Including a high-grade zone of:

2m at 34.84g/t gold equivalent and 14 per cent combined base metals from 23m (0.41g/t gold, 1,825g/t silver, 0.33 per cent copper, 7.55 per cent lead, 6.12 per cent zinc).

Robust Resources said it considers the results, when combined with previous results and geological logging of holes where assay results are awaited, indicate the western flank of the Perak Basin remains open for further discovery.
The company claimed high-grade manganese mineralisation was also encountered in Perak Basin during the recent round of drilling, intersecting zones grading more than 40 per cent manganese.
The company said drilling and data compilation remains on track for completion of a new Romang Island mineral resource estimate by first quarter CY2014.

Additional drilling to extend this resource will be the focus of Robust’s 2014 drilling campaign.

“As the 2013 drilling year on Romang Island draws to a close, it is an opportune time to reflect on our achievements during the past 12 months,” Robust Resources managing director Gary Lewis said in the company’s announcement to the Australian Securities Exchange.

“The company has made significant progress in achieving its aims of commercialising our discoveries on Romang Island.

“We have:

Completed the maiden independent JORC mineral resource estimate of our high-grade manganese deposits;

Discovered the exciting high-value Perak Basin VMS deposit;

Discovered the ultra-high-grade Batu Mas Deeps polymetallic sulphide deposit;

Completed record diamond drilling for any year of over 12,000 metres;

Significantly advanced the geological understanding and orebody models; and

Reformulated the development strategy to a low-risk, low CAPEX pathway based on high-grade mineral deposits and commenced execution of that strategy.

“2014 should be a watershed year for Robust and I look forward to sharing more excellent results including a mineral resource update for Romang Island in the early part of the year.”
