Gold and silver were adding to yesterday’s gains to close out the week’s trading Friday morning as Facebook’s IPO, a Greek exit and contagion worries continued to grip world financial and commodities markets.

Spot gold was up 1.17%, bid at 1,592.70 an ounce as of 11:07 a.m. Prices reached as high as $1,598.80 and as low as $1,584.70, according to Kitco market data. The London afternoon reference price was set at $1,589.50, $13 an ounce below Thursday’s afternoon reference price.

Gold bullion prices rallied for a second straight morning in London Friday, reaching as high as $1,594 an ounce, BullionVault reported. “The bulls staged a big counterattack,” BullionVault quoted the latest technical analysis note from Scotia Mocatta.
