HANOI, June 9 (Reuters) - Copper prices advanced on Wednesday, supported by worries about potential disruptions in supply in Peru and Chile, the world's top two producers of the metal.

Three-month copper on the London Metal Exchange rose 0.3% to $9,995.50 a tonne by 0143 GMT, while the most-traded July copper contract on the Shanghai Futures Exchange was up 0.8% to 71,930 yuan ($11,246.27) a tonne.

Early results in Peru's presidential elections showed Socialist Pedro Castillo was narrowly in the lead on Tuesday. He had pledged to take up to 70% of profits from firms mining in the country's copper-rich Andes.

Meanwhile, a royalty bill proposed in Chile to tax copper sales and labour talks at miner BHP's mining operation in the country could hinder supply.
