LONDON, Aug 6 (Reuters) - Gold soared to two-month highs on on Thursday, boosted by inflation worries that were stoked by news Britain would pump more funds into the banking system than expected, citing fragile financial conditions.
Gold, which is often seen as a hedge against rising prices, rose to $971.25 an ounce, its highest since June 5, but a firmer dollar, which makes commodities more expensive for holders of other currencies, capped gains. [
]Spot gold <XAU=> was bid at $965.15 an ounce at 1526 GMT, against $961.95 an ounce late in New York on Wednesday.
"People are starting to get worried about banks having things too loose for too long," Citigroup analyst David Thurtell said.
The Bank of England stunned markets by extending its quantitative easing programme to 175 billion pounds ($297 billion) from 125 billion, beyond a previous limit of 150 billion pounds. [
]But gold fell from its intra-day peak after the European Central Bank said it expected price stability to be maintained. [
]Commerzbank analyst Eugen Weinberg said both inflation worries and technical factors were at play, and that a stronger dollar would undercut bullion's rally.
"Should the dollar rally towards $1.42, $1.43 (versus the euro) I could imagine gold would suffer," he said.
OUTPUT RISES
In supply news, Gold Fields <GFIJ.L>, the world's number four gold producer, said its output of the metal rose 4 percent in the fourth quarter while production costs fell 6 percent to $512 an ounce. [
]On the demand side, buying of gold to back exchange-traded funds remains slack, with holdings of the SPDR Gold Trust <GLD>, the largest bullion ETF, unchanged for a fifth day on Wednesday.
Sales in the world's main gold jewellery market, India, were also lacklustre as banks were shut by a strike. [
]Among other precious metals, silver <XAG=> rose 0.8 percent to $14.76 an ounce against $14.64.
The world's largest silver producer, Fresnillo <FRES.L>, said its board had approved a pre-feasibility study for the development of its Saucito project in Mexico, which could produce up to 9 million ounces of silver a year.
This is equivalent to more than 1.3 percent of annual global production, which stood at 680.9 million ounces last year.
Platinum <XPT=> dropped to $1,275 an ounce against $1,282.50, while palladium <XPD=> was at $272.5 against $273.
Traders have taken profits in both metals after they hit multi-month highs on Wednesday amid talk of a strike at South African power company Eskom.
The union said on Thursday it will march to press state utility Eskom for better wages, as the company braced for a possible strike that could disrupt power in the world's biggest platinum producer. [
