Nov 3 (Reuters) - Copper prices advanced on Wednesday, as low stockpiles in exchange warehouses lent some support to the metal after sharp losses in recent weeks.

Three-month copper on the London Metal Exchange rose 1.4% to $9,630 a tonne by 0746 GMT, having lost 7.9% since Oct. 18.

The most-traded December copper contract on the Shanghai Futures Exchange closed up 2% at 71,350 yuan ($11,151.23) a tonne, following two straight weeks of declines.

"Looks like we've found a floor at the moment. There's been enough days of dropping. There's no harm starting to pick small positions," a Singapore-based metals trader said.

"Inventories are still dwindling, so this downwards flat price momentum too has its limits."

On-warrant LME copper inventories edged up to 31,675 tonnes, but still hovered near their lowest since 1998 of 14,150 tonnes hit on Oct. 14.

LME cash copper premium over the three-month contract were at $275 a tonne, indicating tight nearby supplies.

ShFE copper stocks rose for the first time in three weeks last week to 49,327 tonnes, but were still down some 80% from May.
