Zinc futures gained 0.97 per cent to Rs 104.15 per kg today, as speculators built up fresh positions, tracking a firming trend in base metals overseas.
Analysts said the rise in the metal prices at futures trading was attributed to hopes that the dollar will weaken further, as the US Federal Reserve will take measures to bolster the world's biggest economy.
They said a better trend in the physical markets on the back of pick-up in demand from consuming industries also influenced prices.
At the Multi Commodity Exchange counter, zinc for November contract delivery rose by Re one, or 0.97 per cent, to Rs 104.15 per kg, with a turnover of 249 lots.
The metal for October delivery also edged up by Rs 1.05, or 0.93 per cent, to Rs 103.05 per kg, with a business turnover of 4,067 lots.
Meanwhile, zinc at the London Metal Exchange surged by 1.4 per cent to $2,345 per tonne, the highest level since April 29.
