London copper is headed for its biggest weekly gain since 1979, with a ton of the metal rising more than $1,000 dollars since Monday, skipping past $6,000 per ton at one stage in Friday trade.
Prices for industrial metals move along with signs of rising or falling economic growth and while copper is the current red-hot bet, silver is being tipped to follow, according to one analyst.
The metal is heavily used in electrical power switches, machinery control panels, batteries and radiography.
Daryl Guppy, CEO of Guppytraders, told CNBC Friday that silver prices are easy to predict as the trading action is currently lagging gold.
"So [when] I look at gold, I've got a three-four day window of opportunity to see how silver will behave," he said.
And Guppy said while industrial demand does suggest an upside for silver, it is the charts that are making him fall "in love" with the metal.
"Yes we have got the fundamentals involved but from a charting perspective, silver is the way to go for better returns," he said.
"Silver is the trade because it has much more leverage. It is coming from a lower price," he said.
