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."
