Drilling success continues at Romang Islang gold project: Robust

ASX-listed Robust Resources Limited announced Tuesday the latest assay results for two diamond drill holes from the Purple Heart prospect situated within the highly mineralised Lakuwahi Caldera on Romang Island in Indonesia.
?In keeping with previous assay results from Purple Heart, both holes have intersected strong gold, silver and base metal mineralization,? the company said in a statement. ?Sixteen holes have now been drilled at Batu Perak including 10 at Purple Heart with each one intersecting significant gold-silver mineralisation, some also with base metal values.?
The company said that following a recognised pattern, the upper sections of drill hole LWD 324 shows enhanced assays for gold and silver, whereas the lower section is pervasively mineralised in base metals: lead, zinc and copper - also with significant gold and silver.
Results from LWD 324 include:
? 51m at 1.49 g/t AuEq1 & 1.94% BM2 from 0m (0.73 g/t Au, 36 g/t Ag, 0.29% Cu, 0.84% Pb, 0.80% Zn) with sub intervals::
o 14m at 1.76 g/t AuEq & 1.14% BM from 2m (1.01 g/t Au, 35 g/t Ag, 0.34% Cu, 0.62% Pb, 0.18% Zn)
o 13m at 1.82 g/t AuEq & 4.24% BM from 36m (0.65 g/t Au, 55 g/t Ag, 0.53% Cu, 1.72% Pb, 1.99% Zn)
The intersection in LWD 324 is particularly significant as it demonstrates that the Purple Heart zone remains strongly mineralised at the northern-most limit of the current drilling pattern. This, combined with the orientation of the mineralised outcrops and geophysical evidence, suggests that there may be a continuous zone of mineralisation beneath thin limestone cover, between Purple Heart and Batu Mas.
Robust?s Managing Director Gary Lewis commented: ?Assay results continue to demonstrate that Romang Island has multiple structures with high mineralisation. Hole LWD 324 is another example of this, and the thick zones of gold and silver-rich polymetallic mineralisation are now the focus of current metallurgical test work. This test work is aimed at a new concept of processing both oxide and sulphide ores through a sizeable flotation plant, conceivably achieving enhanced metal recoveries overall and a more economic outcome.?
