Further drilling by Robust Resources at the Batu Putih trend on Romang Island has confirmed a significant new silver discovery. The large-scale silver mineralization has been proven by a third strong intersection from near surface. The zone remains open along strike to the northwest and laterally.
The Batu Putih trend hole intersected 129 metres from 7 metres @ 61 grams/tonne silver, including sub-intervals of 58.9 metres from 8 metres @ 122 grams/tonne, 22.2 metres from 9 metres @ 194 grams/tonne and 13 metres from 49.4 metres @ 130 grams/tonne. The hole also intersected a gold-rich zone at 106 metres including 6 metres @ 1.69 grams/tonne gold.
The hole was drilling 80 metres along strike to the southeast of a previous hole which also intersected broad silver mineralization of 142 metres @ 40 grams/tonne silver including 11 metres @ 109 grams/tonne and 8 metres @ 166 grams/tonne.
Robust continues to explore aggressively on Romang Island with seven diamond drill rigs operating across a number of highly prospective targets. Due to the significant Batu Putih results, an eighth diamond rig is being recommissioned to fast-track exploration at the silver targets.
Massive and deeper silver mineralization at Batu Putih has encouraged Robust’s Board to commence a new conceptual study, introducing flotation at an earlier stage, and mining and processing the Lakuwahi deposits at a higher throughput than previously anticipated. At the same time the company is also assessing a lower capex start-up mining operation targeting high-grade manganese ore, which may generate an early stage cash flow.
Robust’s managing director Gary Lewis says, “It is evident from the 35,000 metres of diamond drilling undertaken to date, and these recent assay results, that the Lakuwahi prospect hosts a sizeable silver-gold polymetallic system. With seven rigs operating and an eighth to commence shortly, it is clear that the mineralized system and resource base on Romang is expected to keep growing.”
