Oct 30 (Reuters) - Most non-ferrous metals prices climbed on Monday as stimulus measures from top consumer China boosted sentiment, with low inventories and solid demand further supporting copper prices.

Three-month copper on the London Metal Exchange was up 0.3% at $8,126 per metric ton by 0602 GMT.

The most-traded December copper contract on the Shanghai Futures Exchange advanced 1.2% to 67,400 yuan ($9,210.54) a ton.

Yangshan copper premium hit $91.50 a ton late last week, more than tripling since the start of August and the highest since November 2022, indicating rising needs to import copper into China.

Profits at China's industrial firms extended gains for a second month in September, adding to signs of a stabilising economy as the authorities launched a burst of supportive policy measures.

Chinese lawmakers last week approved 1 trillion yuan worth of bonds to reform disaster-hit areas, which would require metals for construction.

Inventories of copper in SHFE warehouses dropped to 478,725 tons, the lowest since Feb. 6.

"The tight supply of scrap copper has stimulated an increase in refined copper consumption," said Huatai Futures in a report.

"The domestic one-trillion policy has marginally boosted market confidence, and macro pressure has eased," the report said.

LME aluminium rose 0.5% to $2,232 a ton, zinc advanced 0.3% to $2,480, tin increased 0.6% to $25,055, while lead fell 0.5% to $2,112.50 and nickel eased 0.2% to $18,345.
