LONDON, Sept 4 (Reuters) - Britain's leading share index was up 0.8 percent at midday on Friday as a broad-based rally ended a three-day losing streak, with heavyweight miners and financials leading gainers ahead of U.S. jobs data.
By 1041 GMT, the FTSE 100 <
> was up 40.32 points at 4.837.07. The benchmark is up 14 percent this quarter, on track for its best quarterly rise since the fourth quarter of 1999.Thin volumes accentuated the surge in prices as traders continued to make their way back from summer holidays, with the FTSE 100 trading at 30 percent of its 90-day average volume.
Miners were in demand as gold <XAU=> flirted with $1,000 an ounce. The precious metal is seen as a traditional safe haven and has seen renewed interest from investors in recent days.
Gold miner Randgold Resources <RRS.L> was up 1 percent, while BHP Billiton <BLT.L>, Anglo American <AAL.L>, Xstrata <XTA.L> and Kazakhmys <KAZ.L> put on 1.4-4.1 percent. Lonmin <LMI.L>, the world's third biggest platinum producer, surged 7.4 percent on speculation former suitor Xstrata <XTA.L> would renew a takeover bid after regulatory restrictions lapse next month.
Rio Tinto <RIO.L> advanced 2.4 percent. The miner has suspended iron ore price talks with Chinese steel mills after its top salesman in China was detained, Australia Associated Press quoted Rio's iron ore boss as saying. [
]U.S. non-farm payrolls figures and unemployment rate, due at 1230 GMT, will provide further insight into the state of the world's largest economy.
"Investors are eyeing the jobless figures ... although we've been dragged 40-odd points higher we're not keen on making further gains until we've seen the figures," MF Global broker Neil Adams said, adding investors have sought oversold stocks and were now "sitting on their hands" waiting for the figures.
U.S. employers were forecast to have cut 225,000 jobs in August, down from 247,000 in July. The unemployment rate was forecast to have edged up to 9.5 percent from 9.4 percent.
"We've had two disappointing numbers already this week (APD and Weekly Jobless numbers). Anything in and around the number and the market may have a bit of relief and move higher again," said Adams.
FINANCIALS, ENERGY WANTED
Banks, one of the biggest beneficiaries of government stimuli, were higher. HSBC <HSBA.L>, Barclays <BARC.L>, Lloyds Banking Group <LLOY.L>, Royal Bank of Scotland <RBS.L> and Standard Chartered <STAN.L> added 1.2-2.9 percent.
Insurers also joined in the rally. Aviva <AV.L>, Legal & General <LGEN.L> and Prudential <PRU.L> gained 2.7-4.1 percent.
Oils rebounded from the previous session's sell-off, and ahead of the meeting of OPEC ministers in Vienna next week when they are expected to convince the group to hold output steady for now, with crude around $68 a barrel.
Cairn Energy <CNE.L>, Tullow Oil <TLW.L>, BG Group <BG.L> and Royal Dutch Shell <RDSA.L> rose 0.1-2 percent.
UPGRADES
UBS increased its estimates of earnings per share (EPS) growth for European corporates for 2010 to 25 percent from 15 percent, citing continuing improvements in the economy.

Vodafone <VOD.L> advanced 1.8 percent. The Financial Times reported Deutsche Telekom <DTEGn.DE> had held preliminary talks with Vodafone, France Telecom <FTE.PA> and Spain's Telefonica <TEF.MC> over the sale of its T-Mobile UK unit.
