Copper prices advanced Tuesday on a potential supply disruption amid labor unrest in Chile.
The base metal gained 0.13% to $5,844 a metric ton in Tuesday morning trading. Gold, meanwhile, fell 0.31% to $1,209 a troy ounce.
Workers at Antofagasta PLC and Barrick Gold Corp.'s Zaldívar copper mine, which produced a little over 103,000 metric tons of copper content in 2016, voted to go on strike after wage negotiations failed, said analysts at ING Bank.
The workers still need to seek government mediation before actually going on strike, which could come as early as the start of next week, said Robin Bhar, head of metals research at Société Générale.
"Mine disruptions early this year were helping the price and I suspect that will be the case the second half this year," said Mr. Bhar.
Gold, however, continued a downward trajectory as the dollar continued to strengthen amid expectations for an interest-rate increase sometime this year.
The WSJ dollar index, which compares the dollar against a basket of currencies, was up 0.11% to 88.46. A stronger dollar makes it more expensive for holders of other currencies to purchase dollar-denominated metals.
Investors are awaiting a raft of speeches this week from U.S. Federal Reserve members and Chairwoman Janet Yellen. Data on U.S. retail sales, industrial production figures and the consumer-price index will release on Friday, providing further clues on the health of the economy and the central bank's intentions.
Among precious metals, silver fell 1% to $15.47 a troy ounce, palladium increased 0.13% to $838.40 a troy ounce and platinum was down 0.49% to $897.50 a troy ounce.
Among base metals, zinc rose 0.59% to $2,791 a metric ton, aluminum increased 0.18% to $1899.50 a metric ton, tin dropped 0.08% to $19,840 a metric ton, nickel was up 0.55% to $9,060 a metric ton and lead jumped 0.24% to $2320.50 a metric ton.
