LONDON, June 26 (Reuters) - Copper eased on Monday after U.S. durable goods data missed forecasts, though expectations for upbeat Chinese demand and concerns over mine supply kept the metal underpinned near Friday's 11-week high.
Among other base metals, lead reached its highest in nearly eight weeks and zinc moved back towards Friday's 11-week peak as on-warrant London Metal Exchange stocks -- metal not earmarked for delivery and therefore available to the market -- hit their lowest in nearly a decade.
Copper remained under pressure, however.
"You could argue that the durable goods orders are playing their part in this," Commerzbank analyst Daniel Briesemann said.
The metal is still holding near Friday's peak of $5,854.50, its highest since April 7, and is up nearly 5 percent in the year to date, supported by major outages at copper mines in Chile and Indonesia and hopes for buoyant demand.
"We've had some reasonably good data on the demand front out of China in terms of state power grid authorisations, better automobile production, a stable housing market," Societe Generale analyst Robin Bhar. "At the same time you've had supply concerns returning."

* COPPER STOCKS: Copper inventories in London Metal Exchange warehouses MCU-STOCKS fell another 4,025 tonnes on Friday, exchange data showed, and are now down nearly 100,000 tonnes, or 28 percent, from their early May peak.
* POSITIONING: Hedge funds and money managers cut their net long position in copper futures and options by 13,552 contracts to 49,285 in the week to June 20, U.S. Commodity Futures Trading Commission data showed on Friday.
