+++++++++++++++++++++++++ * coarse gold indicated by Screen Fire Assays, intersected grades enhanced
* follow up drilling planned for mid June 2003
The Directors of Giralia Resources NL are pleased to report that Screen Fire Assaying has enhanced intersected grades and indicated the likely presence of significant coarse particulate gold in drill samples from the Mixy lode at the Snake Well Joint Venture in Western Australia. Mount Isa Mines Ltd ("MIM") can earn a 60% interest in the Snake Well project through expenditure of $3 million over the next 5 years.
Gold mineralised 4 metre composite samples from drilling completed last month at Snake Well were riffle split in 1 metre intervals and analysed by both 50 gram aqua regia digest AAS determination, and 500 gram Screen Fire Assays. There is significant variation between results from the two analytical methods, with Screen Fire Assay grades averaging almost 50% higher than aqua regia digest analyses. A large proportion of the gold in mineralised intercepts reported to the coarse (+75 micron) fraction, indicating the presence of significant particulate gold.
INTERSECTION G/T AU HOLE NO FROM TO (METRES)(METRES) AQUA REGIA-AAS SCREEN FIRE ASSAY % UPGRADE
* intersections calculated using a 0.5 grams per tonne gold (g/t Au) lower cut-off grade, with up to 3 metres of included internal dilution
These 3 holes, along with previous intersections of 14 metres @ 9.95 g/t Au and 13 metres @ 5.08 g/t Au, define a 150 metre long, steeply dipping mineralised zone at Mixy, open along strike and at depth.
Follow up drilling to test strike extensions is planned for mid June 2003. Drilling will also better define extensive near surface laterite mineralisation at Snake Well to allow preliminary resource estimation.
