Robust Resources Limited recently completed its first phase, 167 line kilometre, 3D Induced Polarization (IP) survey at the North Romang Project. Significant IP anomalies have now been modelled in areas that have coincident soil geochemical and aeromagnetic anomalies. Along with prospective surface geology, the data all supports the model for a large-scale porphyry-style target.

The major IP anomalies are located within the Wyaru Prospect Grid area of the North Romang Project occur over a substantial proportion of the gridded area (Figure 1) and have a N-S strike of 4.5 kilometres and are open to the south. The anomalies extend in depth to the limit of detection of the IP method, which is greater than 500 vertical metres.

The large-scale IP anomalies further enhance the prospectivity of the North Romang project and are the key factor which has determined the design of a 5,000m exploration diamond drilling program which is to commence in June 2011.

Robust has previously described the prospective outcrops of altered and mineralised volcanic and intrusive rocks which outcrop along the north coast of Romang Island. Commencing in 2010 the company undertook an extensive program of gridding, geological mapping, soil sampling and geophysics. The mapping has identified a large package of highly altered, strongly leached, andesitic volcanic and quartz diorites along with multi-element soil geochemical anomalies. This altered and mineralised rock package corresponds well with the previously described radiometric anomaly and vegetation anomaly.

The internal structure of the IP anomalies is interpreted as being an “anticlinal” structure which fits well with the porphyry intrusive model for the mineralisation (Figure 2).
