Silver prices were rising 26 cents to $19.56 while copper was down 2 cents to $3.18. Silver was maintaining its appeal as the "poor man's gold" as investors bought the metal as a cheaper alternative to four-digit gold prices. Copper was largely left out of the precious metal rally as concerns over slowing spending in China weighed on demand for the precious meal. Gold stocks, a more risky but more profitable way to invest in gold, were mixed after their big rally Tuesday. Barrick Gold ( ABX) was down 0.48% to $45.66 while Newmont Mining ( NEM) was up almost 1% to $58.72. Other large-cap miners Kinross Gold ( KGC) and Goldcorp ( GG) were trading at $19.24 and $46.19, respectively. Shares of Freeport McMoRan Copper & Gold ( FCX) were up over 3% to $73 while Randgold Resources ( GOLD) was higher by 1.14% at $90.77. Shares of the gold ETF, SPDR Gold Shares ( GLD) were adding 0.51% to $121.27. The gold ETF did not add any tonnage Tuesday despite a new 52-week high for the stock and record high gold prices. The ETF currently holds 1,192 tons of gold.
