NEW YORK/LONDON, Aug 27 (Reuters) - Gold futures ended slightly higher Thursday on a weaker dollar and better equities market amid improving overall economic sentiment, prompting investors to buy precious metals across the board.
Platinum group metals also rose, supported by labor actions and supply worries in South Africa, where Impala Platinum <IMPJ.J> said on Thursday thousands of striking workers could be sacked, and Aquarius Platinum <AQP.AX> laid off 3,900 strikers. [
]The price of gold has been largely confined to a trading range between $930 and $960 in the past three months, as the metal was pressured by a resurgent dollar but supported by long-term inflation worries and lingering economic uncertainties.
Adam Klopfenstein, senior market strategist at Chicago-based Lind-Waldock, said that gold was pressured by market forces outside of the commodities sector, as the metal has recently failed to rally on upbeat economic news.
However, the fact that gold was able to hold at historically high levels underscored the metal's safe-haven appeal amid uncertainties.
"If we see a sustained equites sell-off, that would be another bullish factor in the gold," Klopfenstein said.
U.S. December gold futures <GCZ9> settled up $1.50 at $947.30 an ounce on the COMEX division of the New York Mercantile Exchange.
Spot gold <XAU=> was at $947.60 an ounce at 2:06 p.m. EDT (1906 GMT), against $944.10 an ounce late in New York on Wednesday.
With little fresh supply and demand news reaching the market, gold, however, remains tied to the dollar, analysts said.
"The only driver of gold appears to be the dollar," said Calyon analyst Robin Bhar. "As we move into September and October it is the Indian wedding season, and maybe some uptick in physical buying will allow a bit of a breakout."
The dollar index <.DXY>, which measures the U.S. unit's performance against a basket of six other currencies, turned lower as Wall Street rebounded. [
]Gold trades in a close inverse relationship with the dollar, as it is often bought as an alternative asset to the U.S. currency. It also becomes cheaper for holders of other currencies when the dollar is weak.
SAFRICA STRIKES EYED
Among other precious metals, silver <XAG=> was at $14.25 an ounce against $14.30. Platinum <XPT=> was at $1,238.50 an ounce against $1,232, while palladium <XPD=> was at $284.50, against its previous session close at $284 an ounce.
The platinum group metals were being underpinned by strike action at Impala Platinum's Rustenburg mine in South Africa, where more than 20,000 workers have been striking since Monday over wages.
Chief Executive David Brown said on Thursday the company could carry out mass dismissals of striking workers. The work action was cutting output, he said, as the company does not hold a "significant amount" of ore stocks. [
]Aquarius Platinum <AQP.AX> said it had dismissed 3,900 workers as a result of industrial action. [
]Platinum prices have not yet reacted significantly to the news. Analysts say a lack of demand for the autocatalyst metal this year has made the market less sensitive to supply outages.
