Robust Resources has confirmed its most significant assay to date at the Romang Island project, with an intersection of 59.6% manganese from three new drill holes. The holes specifically targeted manganese mineralization, with each of them intersecting significant widths and grades of manganese.
Some of the best results include 26.7 metres @ 40.5% manganese including 2 metres @ 59% manganese, 14.2 metres @ 48% manganese including 6 metres @ 56.4% manganese and 21.1 metres @ 37.5% manganese including 5.1 metres @ 53.1% manganese.
Robust says the mineralization remains open in three directions with consistency of manganese across the confirmed mineralized area. The company is awaiting assay results from a further 11 holes, many of which show visible manganese mineralization in the drill core.
“Strong results from exploration efforts at Manganese Valley present Robust with a new opportunity. The theoretical maximum manganese content for pure manganese dioxide is 63% and our peak assay of 59.6% manganese approaches that purity. This gives us every confidence that we have a high-grade deposit,” says Robust managing director Gary Lewis.
The company has now designed an exploration program specifically to target manganese mineralization. “These results are a further indication of prolific mineralization on Romang Island and given our strong funding position, we have the financial flexibility to fast-track our manganese exploration efforts on Romang in 2013,” says Gary Lewis.
Robust’s Romang Island site encompasses four deposits - Batu Hitam, Batu Mas, Batu Jagung and Batu Perak. It was originally a precious metals target, with the company focusing on near-surface gold and silver, but has now become a significant polymetallic base metal zone.
