These products have been entered into a GIS database which includes past drilling and geological data. Examples of these products are shown on Figures 1 and 2 which show locations of previously disclosed Rio Tinto (1977-1978) and Santos (1981) drill holes (Refer to RCH ASX releases dated 5 February 2008 and 22 February 2008).

This data provides a good foundation for the next stage of the geological evaluation of all the tenements and has highlighted additional areas which are currently under application. These include the previously identified anomalies A, S and T shown on Figure 2 in RCH ASX release dated 5 February 2008.

The Company's geologist has prepared a work programme and budget which will be presented to Toli Toli Government representatives next week.
