        IVU-V UPDATE 
       
        INDUCED POLARIZATION TARGET ON EL TABACO ENLARGED 
       
        The company has completed additional geophysical surveying to extend the 
        open 
        anomaly reported in our news release of January 21, 2003 from a strike 
        length of 1.5 kilometers to a strike length of 2.4 kilometers with a width 
        of 400 to 500 meters. Additional crosslines to test the anomaly at greater 
        depths of 250 to 300 meters indicate excellent continuity along strike 
        and at depth. 
         
        The anomaly 
        is generally overlain by visible oxide copper development with residual 
        chalcopyrite (primary copper sulphide) occurring occasionally as coarse 
        clots. A central portion of the anomaly measuring about 800 by 300 meters 
        was previously drilled (1963-64) and reported a weighted average of 1.03% 
        leachable copper in 48 holes mineralized from surface to about 30 metres 
        . One hole, only, was drilled to 75 meters and also reported 1.03% leachable 
        copper with grades up to two percent near bottom where associated with 
        chalcocite (secondary copper sulphide). No holes were drilled deep enough 
        to test the induced polarization anomaly. 
         
        A structural feature cutting through the drilled area was formerly high 
        graded for gold and silver and there is evidence of elevated gold distributed 
        in the oxide 
        mineralisation. The target is a large copper-gold-silver mineralised system 
        that merits further attention.
