* Brent backs off $120, sources say Saudi can boost supply
* Inflation concerns remain
(Updates prices)

LONDON, Feb 24 (Reuters) - Gold was flat on Thursday after sources said Saudi Arabia was able to boost crude output, easing from its highest in nearly two months on concerns about inflation after oil rose on unrest in oil-producer Libya.
Violence in Libya, Africa's third-largest producer of oil, sent crude futures to their highest in over two years, around $120 a barrel, a level that Deutsche Bank called a "key threat to global growth". [
]But oil prices slipped from highs after senior sources said Saudi Arabia was willing and able to plug any oil supply gap due to unrest in Libya. [
]Spot gold <XAU=> was up 0.04 percent at $1,412.10 an ounce by 1617 GMT, off a session high of $1,417.92 and having rallied since late January since late January when protests intensified in Egypt against former president Hosni Mubarak.
U.S. April gold futures <GCJ1> were flat at $1,413.20.
"The major factor currently for commodities in general including gold is the situation in Libya and fears it might spread over to other oil producing countries in the Middle East and North Africa," Peter Fertig, a consultant at Quantitative Commodity Research, said.
"It is the safe haven aspect which plays a role and also the rise of crude oil, which could translate sooner or later in rising CPI figures."
As many as 1,000 people may have been killed in the unrest in Libya, as forces loyal to Muammar Gaddafi launched a counter-attack as rebels threatened the Libyan leader's grip on power by seizing important towns near the capital. [

GOLD HEDGE
Investors often buy gold as a means of protecting their portfolios against rising inflation expectations as gold rises in line with other asset prices, as opposed to bonds where returns are eroded, or currencies, which lose purchasing power.
Rising inflation eventually leads to rising interest rates, which ultimately can prove negative for gold, which bears no yield, but when inflation threatens growth, bullion can often offer investors the hedge they need.
The unrest across North Africa and the Middle East boosted other perceived safe-haven assets such as the Swiss franc, which hit a record against the dollar <CHF=>.
"There is no reason why we can't break through the recent high around $1,416 and head towards $1,420 if the unrest continues in Libya," said Darren Heathcote, head of trading at Investec Australia.
"Of course if it spreads even further in field or becomes more violent, gold will benefit further as a safe haven."
Investor interest in gold has not translated into inflows into major exchange-traded products, such as the SPDR gold trust <GLD>, or ETF Securities' gold funds, since the protests in Egypt in late January.
Yet investors have increased their holdings of COMEX gold futures <0#GC:> this month and until the price broke above $1,400 an ounce this week, dealers had reported fairly healthy consumer buying.
The rally in the last four weeks has attracted sales of scrap into the market, which has acted as something of a headwind for the spot gold price, dealers said.
Silver, which is around its highest in 31 years, eased on Thursday, in line with a decline in industrial metals.
Adding to the modest pressure on silver was a decline in import of the metal in January by top commodity consumer China, where it is used, among other applications, in the country's growing solar energy sector. [
]Spot silver <XAG=> was last down 1.3 percent at $33.07 having touched 31-year peaks above $34 on Tuesday.
Reflecting healthy investor interest in silver, where the futures market shows near-term prices are now above those for later delivery, holdings in the world's largest silver-backed ETF, the iShares Silver Trust <SLV>, rose to one-month highs.
Platinum <XPT=> fell 0.3 percent to $1,775.5 an ounce, while palladium <XPD=> was down 1.7 percent at $762.97. (Additional reporting by Rujun Shen in Singapore; Editing by Alison Birrane and Sue Thomas)
