update of the Mining Lease renewal for the Mae Sot mine

[Translation] Ref. PDI/BK-BS-083/2007 28 December 2007 To : President The Stock Exchange of Thailand Re.: Padaeng Industry update of the Mining Lease renewal for the Mae Sot mine The Company would like to inform to the Stock Exchange of Thailand the progress of the renewal of the Mining lease on the existing premises at Mae Sot as follows: The operations at the Mae Sot mine have been suspended since October 18,2007 after the expiry of the mining lease and the Tak smelter has been using the accumulated stocks albeit at a slightly reduced rate compared with previous quarters. To date, the company has encountered significant delays with the approval procedure. However, the company is making significant progress and is confident that the licence for the mining lease will be approved in the coming months. The company can rely on stockpiles of its own concentrates to feed the Tak smelter until the end of the second quarter 2008, keeping the mine contribution in the feed around the current rate. When the mine reopens, the smelter should resume using its own concentrates at approximately the same rate as in the first half of 2007. The company does not anticipate any impact in terms of deliveries of zinc products for its regular customers. Please be notified accordingly.
