Aug 4 (Reuters) - Copper vaulted above the $14,000 mark to a

two-month peak on Tuesday, driven higher by dwindling

inventories outside the U.S. and hopes for a resolution of the

Iran war, even as the status of negotiations was unclear.

Benchmark three-month copper on the London Metal

Exchange jumped above $14,000 shortly after the release of LME

stocks data at 0800 GMT, rising as much as 1.3% to $14,053 a

metric ton, its highest since June 2. The metal was trading up

1.1% at $14,024.50 as of 0900 GMT.

The data showed orders to withdraw another 7,225 tons of

copper from LME warehouses , leaving available

inventory at just 94,200 tons, little more than a day's worth of

global consumption.

That helped push the backwardation in the cash to

three-month spread up to $105 a ton, the steepest

premium since January and a sign of growing tightness.

The copper withdrawals, or cancelled warrants, were mostly

from the U.S. storage hub of New Orleans, where metal can be

transferred to the COMEX exchange for a premium. COMEX

holds more than double LME and Shanghai Futures

Exchange copper inventories combined at 650,736

metric tons.

Meanwhile, conflicting signals from the United States and

Iran over talks to end their five-month-old war fed uncertainty,

with the latest attack on shipping in the Strait of Hormuz

highlighting risks to flows of aluminium as well as energy.

The lightweight metal added 1.2% to $3,259.50 a ton,

touching its highest since June 23.

"Aluminium has reclaimed the $3,200/t area, but we do not

expect prices to hold comfortably at these levels without a

renewed Middle East shock or another clear supply-risk

catalyst," analysts at Sucden Financial wrote in a note.

Nickel rebounded by 1.4% to $17,285 after losing

ground on Monday, with traders awaiting clearer guidance on new

nickel mining quotas in Indonesia.

Zinc edgedup 0.4% to $3,655.50, after striking a

nearly four-year high on Monday, while lead gained 0.9%

to $1,883 and tin rose 0.8% to $55,750 after also

hitting a two-month high.
