Ongoing drilling by Robust Resources at the Lakuwahi project has intersected the richest polymetallic base/precious metal zone to date on Romang Island.
One hole at the Batu Hitam prospect was mineralized for the entire length of 188 metres and included 21.1% combined base metals (lead 12.3%, zinc 7.7% and copper 1.1%) with 1.27 grams/tonne gold and 58 grams/tonne silver.1
It was the first hole to be guided by the company’s recent resistivity results and it intersected visually impressive massive sulphide mineralization.
Initial results from the major 3D IP-Resistivity survey over Lakuwahi as well as new drilling results significantly extend the discovery target zones and, therefore, the gold and base metal resource potential.
Robust’s managing director Gary Lewis says, “The high grade results are very encouraging as the hole expands the known mineralization at Batu Hitam beneath the limestone cover and is also consistent with the new geophysical model.
“The gold and silver bearing massive sulphides are the highest grade yet to be assayed in our two-year long exploration drilling campaign.
“The IP-Resistivity model is still being compiled and interpreted but the interim results are significant. In particular the large anomaly to the south of Batu Hitam as well as more subtle anomalies associated with the strong geological and geochemical indicators at Batu Perak and Batu Hitam North, indicates plenty of scope to continue the achievement of positive drilling results.
“Robust now has four diamond drill rigs operating on Romang with a further two rigs purchased and on their way to the island.”
