Martin Place Securities executive chairman Barry Dawes told the inaugural ResourceStocks Sydney conference this week that "the copper price has got to go much higher as we go forward" - referring to recent data and bullish assessments from red metal majors.
In the US, the S&P500 metals and mining sector gained 2.62% yesterday, largely due to copper producer Freeport-McMoran's (NYSE: FCX) rise of 4.26%.
Toronto's metals and miners sector on the S&P/TSX Composite Index recorded a more subdued gain of 0.42%.
However copper miner First Quantum Minerals (TSX: FM) was up 4.96%, and diversified Ivanhoe Mines (TSX: IVN) rose 3.08%.
The gold sector was lower overall in Toronto but producer Kirkland Lake Gold (TSX: KL) was the best performer with a 1.35% gain.
Meanwhile in Australia, lithium stocks were popular with miners Galaxy Resources (ASX: GXY) and Orocobre (ASX: ORE), plus emerging producer Pilbara Minerals (ASX: PLS), three of the top five risers on the S&P/ASX200 index in afternoon trade.
Galaxy was up more than 8% at the time of writing.
Finally, the gold price was a little lower than yesterday and was trading just below US$1,290 an ounce on the spot market earlier.
