Gold futures edged back above $1,500 an ounce Tuesday, but showed little decisive direction as traders were reluctant to take positions ahead of Greece's closely watched vote on austerity measures.

The most actively traded contract, for August delivery, was recently up $3.70, or 0.3%, at $1,500.10 a troy ounce on the Comex division of the New York Mercantile Exchange.

Futures Monday settled below the $1,500 mark for the first time in more than five weeks, under pressure from a pause in investor demand for a safe-haven and lingering downward momentum after the yellow metal shed more than $50 an ounce in a two-day selloff at the end of last week.

Greek lawmakers are expected to vote Wednesday on an austerity plan to secure financial support from the European Union and International Monetary Fund. Worries about the ability of Europe's monetary union to manage its weaker members' sovereign debt has sent investors into gold during the last 12 months, helping the metal set repeated record highs.

Precious metals are viewed by some as a refuge during instability in other markets on the belief that it holds its value better than other assets.

"Gold and silver remain weak," said William Adams, head of research with FastMarkets. "Given the uncertainty over Greece we are surprised they have not attracted more safe-haven buying."

Silver also ended at a five-week low Monday, but edged higher along with gold Tuesday. July-delivery silver rose 0.2%, to $33.655 a troy ounce.

Some traders were content to stay on the sidelines ahead of the vote, leaving futures little direction. Greek approval of the budget-cutting measures would likely dampen demand for refuge assets such as gold, but could also boost commodities on the back of an expected strengthening of the euro and weakness in the dollar.

Dollar-denominated raw materials such as gold can receive a boost when the greenback falls, as it makes the futures cheaper for buyers using other currencies.

Platinum and palladium, demand for which is largely driven by industrial and automotive uses, outpaced gold's gains early Tuesday. Platinum for July delivery was recently up 0.9%, at $1,687.90 a troy ounce. September-delivery palladium rose 1.1% to $732.40 an ounce.
