Benchmark three-month tin on the London Metal Exchange climbed as high as 11.5% to $27,705 a tonne, a level unseen since Feb. 21. News floated in the market of a possible mining ban in Myanmar's Wa state, the largest tin-producing area in the country, to preserve the remaining ore supply. Reuters has not been able to independently verify the information. "The Wa state is the largest tin mine producing area in Myanmar, and most of its output is sent to China. The ban on mining will undoubtedly make the already tight supply of tin mines even tighter," broker Xinhu Futures was quoted by state-run Shanghai Securities News as saying. However, a trader said it is unclear whether the ban will be implemented and the Xinhu report said "this is not the first time such notifications have been made."
