A further four diamond drill holes at Perak Basin of Robust Resources’ Romang Island project have continued to intersect significant polymetallic mineralization. One of the latest holes included one of the richest high-grade intersections recorded at Romang Island.

The hole intersected high-grade gold, silver and base metals. It returned 19.45 metres from 90.55 metres @ 7.39 grams/tonne gold equivalent and 6.14% combined base metals, including 6.45 metres from 90.55 metres @ 9.92 grams/tonne gold equivalent and 6.14% base metals, 2.0 metres from 99.0 metres @ 10.33 grams/tonne gold equivalent and 9.53% base metals, and 6.0 metres from 103.0 metres @ 8.24 grams/tonne gold equivalent and 12.92% base metals.

The 19.45 metre intersection assayed 68% barite while the hole further extended and enhanced the precious and base metals domain reported from the previous nine holes completed in June at Perak Basin. Mineralization remains open to the southeast. Extensions of this zone will be the target for near-future exploration drilling.

Another of the latest holes revealed two thick intersections of breccia mineralization consisting of an upper zone 53 metres in length and a deeper zone 36 metres in length. The upper zone is likely to be more economically significant as, in common with most holes in the Perak Basin, there is an upper high-grade barite-exhalative (BEX) zone. In this case the BEX is dominated by high silver values.

The upper intersection in this hole includes 7.2 metres from 44.8 metres @ 3.36 grams/tonne gold equivalent and 0.91% combined base metals within a broader zone of 53 metres @ 1.43 grams/tonne gold equivalent and 0.75% combined base metals.

Robust’s managing director Gary Lewis says, “After more than 400 holes and nearly 50,000 metres of diamond drilling we are very encouraged by the significant nature of the recent discoveries in the Lakuwahi Caldera and our technical team is very confident that we will continue to unearth high-grade drill intersections in what is a truly remarkable mineralized system.

”Robust has decided that a new resource model for the polymetallic mineralization is required for project planning work and as a measure of progress to date. Work has already commenced on this modelling and the most recent drilling will be incorporated.

“The company expects to announce an updated mineral resource estimate last this month with work continuing on the island utilizing seven drill rigs between the manganese feasibility study and the ongoing Perak Basin exploratory program.”

Meanwhile, Robust’s Kyrgyz Republic assets have been transferred into a separate AIM-listed company, Tengiri Resources. www.robustresources.com.au
