Profit-taking after a big run-up over the last week knocked gold futures off a one-month high Friday, resulting in a lower close.

August gold traded up to $639.50 an ounce, its highest level since June 6, as the dollar sagged Friday morning in the wake of a softer-than-expected report on June U.S. non-farm payrolls. The metal subsequently fell back as far as $629.50, however, before settling with a loss of $1.50 to $634.80.From the overnight low of $546.40 to Friday's peak, August gold had rallied 17 percent before it pulled back.

"For the moment, it looks as though they ran out of buyers," said Don Tierney, precious-metals analyst with Pell Futures Corp. "So there is general profit-taking, which was more or less expected."

"Despite a weaker-than-expected payrolls reading from the U.S. and the dollar's subsequent reaction, gold and the other precious metals have failed to find significant upside traction, with initial gains in both running into end of week profit-taking," said a research note from analysts with TheBullionDesk.com.

Tierney noted that at the session high, August gold was up $58.50 from the settlement five trading days ago.

"So today's selling looked to be coming out of an overbought situation," he said.

September silver settled down 18 cents at $11.405 an ounce, also hurt by profit-taking.

October platinum lost $5.90 to $1,243.70 an ounce. September palladium dipped $1.70 to $329.15 an ounce.

Most-active September copper settled down 6.95 cents at $3.5475 per pound. During the session, the contract got as high as $3.6050 per pound.
