Pure 1,000-gram gold bars produced by South Korea's LS-Nikko are stacked in a dealers room in Seoul on Jan. 9, 2009.

Gold prices extended gains to a second straight session on Thursday, boosted by a slide in the U.S. dollar and Treasury yields after the Federal Reserve signaled an end to its monetary tightening cycle might be on the cards.

Spot gold last rose 1.18% to $1,992.81 per ounce, while U.S. gold futures jumped 2.4% to settle at $1,995.90.
