Robust Resources confirms potential of Perak Basin VMS target on Romang Island

By Ruli Setiawan

ASX-listed Robust Resources Limited unveiled Tuesday the assay results from 17 holes from recent drilling of the Perak Basin VMS target on the Romang Island project, in Maluku Province.

The company said in a statement that each hole intersected precious metals and base metals including the best polymetallic intersection so far at Perak Basin from hole LWD 403. Assay results from the hole include:
o 144.8m at 1.24 g/t AuEq and 3.74% combined base metals from 57.2m
(0.88 g/t Au, 19 g/t Ag, 0.13% Cu, 1.57% Pb, 2.04% Zn) including:
o 104.4m at 1.66 g/t AuEq and 4.50% combined base metals from 58.6m
(1.17 g/t Au, 26 g/t Ag, 0.16% Cu, 1.91% Pb, 2.44% Zn) and including high-grade zone
o 50m at 2.32 g/t AuEq and 6.06% combined base metals from 75m
(1.61 g/t Au, 38 g/t Ag, 0.21% Cu, 2.65% Pb, 3.21% Zn)

In total, Robust has completed 49 diamond drill holes into the Perak/Perak Basin and from these results Robust?s technical team have confirmed that the Basin has significant potential, including:
1. The Perak deposit is continuous across the drilled part of the Perak Basin (700m x 400m) ? every hole has intersected mineralization.
2. Mineralization is open in all directions, only 25 percent of the Perak Basin has been drilled.
3. The thickest and most intense zones of mineralization have been interpreted as barite-rich feeder systems (BFS), one along the western side and the other in the central south-east part of the basin.
4. The western BFS target is at least 400 meters long and based on 6 drill holes is completely open to the west.
5. The central BFS target zone, including exceptional assay results from LWD 370, 403, 392 and 398, is completely open to the southeast.
6. Geophysical evidence exists for a 3rd, eastern, BFS, which has not yet been drill tested.

Robust?s geologists have concluded that Perak Basin is a very rich and prospective VMS-style precious and base metal-rich system, and that it remains completely open for further discovery. The two highest priority targets (4. and 5. above) are currently being explored with five drill rigs.

Other recent assay results from Perak Basin include:
o LWD 392 from the central BFS:
o 129.9m at 1.02 g/t AuEq and 2.16% combined base metals from 66.1m
(0.88 g/t Au, 19 g/t Ag, 0.13% Cu, 1.57% Pb, 2.04% Zn) including high-grade zone:
o 11.9m at 5.87 g/t AuEq and 4.99% combined base metals from 66.1m
(2.13 g/t Au, 198 g/t Ag, 0.35% Cu, 3.78% Pb, 0.87% Zn)
o LWD 396 from the western BFS:
o 42.0m at 1.60 g/t AuEq and 2.25% combined base metals from 31.0m
(0.78 g/t Au, 43 g/t Ag, 0.09% Cu, 0.78% Pb, 1.38% Zn) including high-grade zone:
o 10m at 2.29 g/t AuEq and 4.58% combined base metals from 33.0m
(1.03 g/t Au, 67 g/t Ag, 0.10% Cu, 1.48% Pb, 3.01% Zn)
o LWD 397 from the Barite Exhalative Zone:
o 7m at 2.91 g/t AuEq and 8.29% combined base metals from 71m
(0.76 g/t Au, 114 g/t Ag, 0.29% Cu, 5.17% Pb, 2.84% Zn)
o LWD 404 from the Barite Exhalative Zone:
o 6.2m at 4.29 g/t AuEq and 5.59% combined base metals from 64.8m
(1.00 g/t Au, 175 g/t Ag, 0.20% Cu, 2.3% Pb, 3.09% Zn)

Robust?s Managing Director Gary Lewis commented: ?The assay results from Perak Basin drilling are again very encouraging. To achieve one of the two best intersections on Romang Island after more than 400 drillholes is a testament to the size and strength of the Lakuwahi Caldera mineralized system. The results will further underpin our expanding mineral resources and increase our understanding of the geology and mineralization.?

?It is now clear that the Perak Basin mineral deposits are much larger than initially predicted and that the targets have the potential to produce a quantum leap in the scale of the mineral resources currently defined by drilling. For that reason Robust has decided to renew its commitment to aggressive exploration and resource definition drilling during 2014. Five rigs are now operating on multiple shifts and all currently focused on Perak Basin resource expansion and exploration,? he added.

Drilling will also be conducted for development purposes including collection of bulk samples for metallurgical testing (both high-grade manganese and polymetallic base/precious metals) and geotechnical investigations for mining and civil engineering purposes.
