Robust updates drilling results from Romang gold project
Tuesday, June 8 2010 - 01:51 AM WIB
Results have been received from two holes from the Company?s key Batu Mas Prospect. Both holes encountered precious metal mineralisation of potentially economic grades and widths significantly extending the identified zones of near-surface, high-grade gold-silver mineralisation. A summary table of the results are located at the end of this report (Table 1), the highlights of which are described below.
The Company believes that the drill results released to date confirm the potential for the Batu Mas Prospect to host world-class gold mineralisation similar to other major deposits in the region.
Diamond drill holes LWD 072 and LWD 074 were positioned to follow up on the outstanding result from hole LWD 051 received in December 2009, which encountered:
57.5 metres at 6.78 g/t Au equivalent (5.28 g/t Au and 90 g/t Ag) from 1.5 metres
Including 27 metres at 9.36 g/t Au equivalent (8.57 g/t Au and 47 g/t Ag) from 3 metres
LWD 072 is located 27 metres to the northwest of LWD 051 and LWD 074 is 37 metres to the southwest. These two holes respectively intersected the second and third strongest zones of precious metal mineralisation encountered in drilling on Romang Island to date.
A summary of the results from hole LWD 072 include:
57 metres at 3.83 g/t Au equivalent (3.17 g/t Au and 40 glt Ag) from surface, including:
? 32 metres at 5.76 g/t Au equivalent (4.69 g/t Au and 65 g/t Ag) from 21 metres; and
? 20 metres at 7.40 g/t Au equivalent (5.98glt Au and 85 g/t Ag) from 29 metres
The high-grade gold zone is underlain by a thick pile of lead-zinc rich base metal mineralised breccias. This zone also carries significant gold and silver. A summary of the intersection is as follows:
54m at 2.75% combined Cu+Pb+Zn (0.52 g/t Au and 21 g/t Ag) from 49 metres
A summary of the results from hole LWD 074 include:
58 metres at 2.71 g/t Au equivalent (2.33 g/t Au and 23 g/t Ag) from surface, including:
? 13.7 metres at 4.47 g/t Au equivalent (3.24 g/t Au and 74 g/t Ag) from 40.5 metres
This hole also intersected a significant zone of copper mineralisatkn of 6.3 metres at 1.69% Cu from 54.2 metres, further underlining the strength and untested potential of the Batu Mas Prospect.
The Batu Mas drill programme is ongoing and currently there are a further nine diamond drill holes at the laboratory for assaying.
Geophysics
The 150 line-kilometre IP Resistivity survey across the Lakuwahi Project is progressing steadily with approximately 20% of the planned area completed. The raw survey data is being monitored on a daily basis by our consultant geophysicists in Perth and early indications are promising. This work is expected to take approximately three months and results will be available as the survey proceeds and will therefore be a useful aid in the early targeting of previously undrilled prospects.
Robust Managing Director Gary Lewis said. ?These latest results are extremely encouraging. They demonstrate the consistency and continuity of the high-grade gold and silver mineralisation across the Batu Mas Prospect, as Robust moves towards delineating a maiden resource. I look forward to keeping our shareholders up to date on the ongoing work and the potential for the Batu Mas Prospect to host a world class project similar to other major deposits in the region.?
