         Runruno Project - Final results of channel sampling of Tunnels

                                   Highlights

     •    Final results received from extensive channel sampling of local 
          miners' tunnels at Runruno Project have returned average grades of 
          4.3 g/t gold; 1,125 g/t molybdenum and 4.8 g/t silver.

     •    Local tunnels (fifty tunnels in total) sampled occur over a distance 
          of approximately 2 kilometres
               
     •    Diamond core drilling anticipated to commence early next month

The Company has now received the last batch of results from its recent
underground tunnel sampling program. The Company is very encouraged by these
results and looks forward to the commencement of a drilling program early next
month.

Results of mapping and sampling of the local miners' tunnels located at the
Balcony 1, Balcony 2, Main Runruno, Tayab and Malilibeg areas have confirmed
the existence of the high grade (>1.4g/t Au) potential of gold mineralisation
(and molybdenum) in the hangingwall and footwall zones of the main Runruno
mineralisation.

A description of how the samples were taken, and what they represent, was
provided in the Company's recent news release dated 27 May 2005. Generally, 5
metre channel samples were taken continuously along the side walls and backs of
the local miners' tunnels. Results of the channel samples represent the grades
of the high-grade material that the local miners have been leaving behind.
the channel samples (315 samples) taken from fifty tunnels have returned 
average grades of 4.3 g/t gold; 1,125 g/t molybdenum, and 4.8 g/t silver.

The local miners' tunnels are located predominantly in the hanging-wall or
foot-wall zones of the main Runruno mineralisation, which has been mapped at
surface over a strike distance of 2.5 kilometres. The local miners' tunnels
occur over a distance of approximately 2 kilometres.

Forward Looking Statement

The Company's objective is to determine a gold (+molybdenum) resource over a 600
metre strike, 100 metres width to a down-dip depth of 400 metres. Given these
parameters, the Directors are setting a resource target for this part of the
deposit of 45 to 55 million tonnes. This is a forward looking statement and
should not be regarded as anything else and should not be regarded as a true
indication of the resource until it has been properly explored.
