BAROBO GOLD CORRIDOR

Figure 1 shows the regional structure and geology highlighting the mineralisation potential in favourable limestone and calcareous clastic rocks along the Barobo Fault Corridor. Mineralisation has been located in numerous outcrops and in drill holes which are summarised in Table 1. The mineralisation located to date is generally associated with silica and sphalerite-galena replacement of the host rocks.

The calcareous sequence along the Barobo Fault Corridor is the same sequence that has been extensively skarned and mineralised at the Kamarangan copper porphyry prospect. This sequence is interpreted as the oldest calacareous sequence known to date in the district and may be up to 1,600 metres thick.
The sequence is regarded as favourable for hosting large disseminated bodies of gold mineralisation.

Table I summarises some of the more significant drill hole intersections from scout drilling (four holes at Guinhalinan, seven holes at Saguilsuilan and six holes at Alikway). The focus of this scout drilling was on potential high grade mineralisation, not potentially open-pittable targets. All show that gold mineralisation is contained with this calcareous sequence. It should be noted, as also shown in soil sampling on Figure 1, that zinc is commonly associated with gold in this environment
