At the Multi Commodity Exchange platform, zinc for October contract delivery gained 85 paisa, or 0.85 per cent, to Rs 100.50 per kg, with a turnover of 14 lots.
Likewise, the metal for delivery in far-month November also edged higher by 60 paisa, or 0.59 per cent, to Rs 101.50 per kg, in a turnover of one lot.
Analysts said apart from strong demand in the physical markets, a firming trend in base metals on the back of dollar weakness boosted the appeal of base metals as a safe investment.
