MILLING OF JACKPOT MINE ORE

Kalgoorlie-Boulder Resources Limited (the “Company”) is pleased to announce that the milling of stockpiled ore from the Jackpot Mine has now commenced.

Milling of the Jackpot ore is expected to be completed in the first week of September and is forecast to yield additional cash to supplement the cash received from the Burey Gold agreement in June 2007.

The Company has completed the current mining campaign at Jackpot.

Now that initial open pit mining at Jackpot has been completed, the Company is in a position to properly evaluate the deep higher grade inferred mineralisation at the Jackpot Gold Project for a possible larger scale open pit or underground operation. During the mining of the “goodbye cut”, a visual inspection of the walls and floor of the mine identified the presence of shears which appear to be highly mineralised. The Company will now carry out additional exploration and mining studies to determine whether further mining operations are possible.
