Gold edged up on Friday, but prices were on track for their biggest weekly drop since the start of the month with an uncertainty about crucial U.S. talks to avert a fiscal crisis continuing to hit sentiment.
While gold has recovered from a 1-1/2-week low of $1,705.64 an ounce hit on Wednesday, it has been unable to break a strong resistance at $1,730 an ounce in a market roiled by conflicting comments from Washington about the U.S. budget negotiations.
Top Republican lawmaker John Boehner said on Thursday that the talks had made little progress, after expressing optimism about reaching a deal with the White House just a day earlier.
If the parties fail to reach an agreement, $600 billion in tax hikes and spending cuts - dubbed as the "fiscal cliff" - will automatically kick off in early January, threatening to push the world's top economy into recession.
"Gold is back in its old $1,700-$1,730 range," said Chen Min, an analyst at Jinrui Futures in the southern Chinese city of Shenzhen, referring to a range in which gold had traded earlier this month.
"On the macro side, the market sees very little direction, while the 'fiscal cliff' talk poses much uncertainty and risk."

PALLADIUM HEADED FOR FIFTH WEEK OF GAINS

"It might be a trade of choice for 2013," said a Hong Kong-based trader. "People don't want to miss it and are pressured to jump in now."
Norilsk Nickel, the world's largest producer of palladium and nickel, expects the palladium market to remain in a deficit in the next several years largely due to a near depletion of Russian state supplies.
In other precious metals, spot silver inched up 0.2 percent to $34.27, on course for a monthly gain of more than 6 percent.
