TOKYO, Feb 8 (Reuters) - Cash platinum was hemmed in a tight band near its record high on Friday as another all-time high in Japanese futures prices provided solid support due to concerns over supply problems in South Africa.
Spot gold <XAU=> was solid above $900 an ounce as the metal was supported despite the dollar jumping more than 1 percent against the euro on Thursday.
"There is no ceiling for platinum now as long as supply worries in South Africa remain," said Tatsuo Kageyama, an analyst at Kanetsu Asset Management in Tokyo.
"You just can't sell platinum considering that the country which supplies 80 percent of the world's supply is facing trouble," Kageyama said.
Cash platinum was trading at $1,842/1,852 an ounce as of 0703 GMT, from $1,841/1,846 late in New York on Thursday when it hit a record $1,850 an ounce.
The spot precious metals market lacked momentum as many Asian dealers are away for the Lunar New Year holiday, but surging Japanese futures prices kept cash prices supported.
The benchmark platinum futures contract for December delivery <0#JPL:> on the Tokyo Commodity Exchange rose 1.8 percent to a record high of 6,119 yen a gram on Friday.
The key TOCOM price has gained about 7 percent since the start of the week.
South Africa has appealed to mining companies for help in cutting power consumption to ease a power crisis caused by the failure of electricity generation to match economic growth.
Platinum producers in the country, which represents about 80 percent of the world's output, are still facing power problems after halting mining operations for five days in January with a significant loss of production.
Spot gold <XAU=> edged up to $909.80/910.70 an ounce, from $908.80/909.50 late in New York on Thursday.
"Gold appears to be lacking momentum, but at the same time we've confirmed that it's very solid," Kageyama said.
Kageyama noted gold managed to stay above $900 by late U.S. trade despite the dollar's rise.
A stronger dollar usually pressures gold, which is largely priced in dollars globally, because it becomes costlier in key overseas trading areas like Europe and Asia.
Gold was supported by news that safety shutdowns and operational woes hit AngloGold Ashanti's <ANGJ.J> fourth-quarter results. The world's third-biggest gold miner said a power crisis would dent future production. [
]Peruvian miner Buenaventura <BUEv.LM><BVN.N> said on Wednesday it would pay $434 million to unwind hedges on gold due for delivery in 2010 and 2012. [
]COMEX gold futures advanced further in Asia after rising in New York on Thursday. The April contract <GCJ8> was trading up $3.9 or 0.4 percent at $913.9 from the New York settlement.
The December TOCOM gold contract <0#JAU:> hit a one-week high of 3,168 yen a gram, up 38 yen or 1.2 percent from Thursday.
