<font class="UCASE"><b>mines found in tibet:</b></font> Chinese geologists have found 600 possible mining sites on the Tibetan plateau for mining iron, copper, lead, zinc and other metal ores. "Once the mines are developed they will greatly relieve the strain on China's existing resources,' said Zhuang Yuxun, lead geologist. One of the biggest potential reserves is an estimated 500 million tonnes of rich iron ore in the Nixiong area, close to the centre of the plateau that covers a vast area inhabited mostly by Tibetans.
