Zinc climbed to its strongest in more than two months on worries about shortages after a shutdown of a production facility in Namibia.
US President Donald Trump said on Friday "good things" were happening in the first trade talks in more than two months, while a Chinese state newspaper said a "partial" trade deal would benefit China and the United States.
"Until we get a definitive outcome, metals prices will drift, but I would expect to see quite a positive response (to any good news). A lot of bad news is priced into the market," said Caroline Bain, chief commodities economist at Capital Economics in London.
"It's very much half-empty sentiment currently."
The 15-month trade dispute between the United States and China has slowed global growth and dimmed the demand outlook for base metals.
US President Donald Trump said his plans to meet China's Vice Premier Liu He at the White House on Friday was a good sign.

MINE CLOSURE: Vedanta Resources said on Thursday it would shut its Skorpion zinc operations in Namibia from early November until the end of February 2020 because of technical problems.
ZINC STOCKS: LME zinc stocks last stood at 62,475 tonnes, having dropped by more than half since the start of 2019. Stocks touched a record low of 50,425 tonnes in April.

LME aluminium slid 1.8pc to close at $1,722 a tonne.
