(Releads, updates prices)

LONDON, Sept 3 (Reuters) - Gold rallied to a three-month peak in Europe on Thursday amid caution ahead of key U.S. non-farm payrolls data on Friday, but eased from highs as the dollar steadied after U.S. ISM services numbers knocked stocks.
Spot gold <XAU=> hit a high of $987.30 and was bid at $983.05 an ounce at 1448 GMT, against $976.60 an ounce late in New York on Wednesday.
Fears U.S. payrolls data may disappoint sparked a flight to quality among investors on Wednesday. The metal broke out of its previous $930-$960 range as a move through technical resistance above $960 sparked a rally.
VTB Capital analyst Andrey Kryuchenkov said gold's immediate move had been largely technical, with the dollar offering little support and physical demand weakening as prices rose.
Gold will need to hold its current levels to build a base for further gains, he said. "If we close above $980 we will retest $990, and probably stay in this range," he said.
The dollar index <.DXY>, which measures the U.S. unit's performance against a basket of six major currencies, softened early on Thursday, boosting interest in the metal as an alternative asset and driving prices to fresh highs. [
]But gold has slipped as the index pared losses, with U.S. stocks falling into negative territory after data showed the U.S. services sector shrank again in August. [
]The market is awaiting fresh clues on the economic outlook from Friday's payrolls numbers. Investors were spooked after a labour market report released on Wednesday showed more private sector job losses than expected. [
]The data will be closely watched for its impact on the dollar, and its subsequent effect on gold. The metal is set to benefit from renewed demand if the U.S. currency slips further.
STRONG INVESTMENT
"Investment demand for gold is still very strong, and that is going to help drive the price higher over time," said Helen Henton, head of commodities at Standard Chartered.
"We think it's going to break $1,000 by Q4, mainly driven by a weakening U.S. dollar."
U.S. gold futures for December delivery <GCZ9> on the COMEX division of the New York Mercantile Exchange rose $6.50 to $985.00. Silver <XAG=> tracked gold higher to reach its highest since June at $15.82, and was later at $15.71 against $15.34.
It outpaced base metals such as copper, with which silver, as an industrial as well as an investment metal, often moves.
"Silver has fully participated in this (rally) and yet while base metals have picked up a bit in the last 18 hours, they were definitely on the defensive," said Stephen Briggs, an analyst at RBS Global Banking & Markets.
"Silver has managed to ignore that, which is interesting."
Among other precious metals, platinum <XPT=> was at $1,236 an ounce against $1,229, while palladium <XPD=> was at $289.50 against $284.50.
Impala Platinum <XPT=>, the world's second largest miner of the metal, said on Thursday some workers at its operations had returned to work after a strike, but said no wage deal had been agreed with the union. [
