SYDNEY, March 3 (Reuters) - Copper futures prices eased on
Friday after striking copper miners in Mexico went back to work,
dousing supply concerns that had driven the market higher this
week.
Three-month London Metal Exchange-traded copper
dropped as much as $35 before recovering to trade $5 lower at
$4,965/$4,975 a tonne following news that strikes at Grupo
Mexico's big Cananea and La Caridad copper mines
had ended after two days.
"That news took the steam out of copper," a trader said.
Traders said they had been looking for further upside moves
in copper after the benchmark futures contract put in a strong
showing in the last London outcry session,erehwit ended $115
higher at $4,970 a tonne on concerns that a lengthy strike would
pinch supplies and drive prices even higher.
Investment interest in copper, which climbed to its highest
price ever -- $5,100 a tonne -- on Feb. 7, had since waned until
the strikes across Mexico that also idled refineries and steel
mills.
"The market was looking for a reason to buy copper again and
the strikes were a perfect excuse," said Bache Financial minerals
strategist Angus MacMillan.
A nationwide wildcat strike at Mexican mines, refineries and
steel mills collapsed on Thursday with union members returning to
work at all of the country's biggest operations.
The strikes began on Tuesday in support of the beleaguered
boss of Mexico's mine union, Napoleon Gomez, who faces a
leadership challenge and government accusations of corruption.
After shutting down the entire mining industry for two days,
most of the union's quarter of a million members went back to
work at Mexico's main plants and mines on Thursday afternoon, the
companies and the union said.
Swelling LME-held copper stocks also took some of the sting
out of supply woes, with the tonnage rising a further 2.7 percent
on Thursday to 118,375 tonnes.
Volume was light across the LME complex, though activity was
expected to pick up if a plan by the LME to extend electronic
trading hours in Asia is implemented.
Britain's Office of Fair Trading this week barred the LME
from extending the electronic trading hours, which had been due
to start on Wednesday in response to a request by rival
electronic trader Spectron. Spectron has since withdrawn the
request.
The most active May copper contract on the Shanghai
Futures Exchange ended the morning session was 1,060 yuan higher
at 46,960 yuan ($5,841) a tonne after trading as high as 47,230
yuan.
Three-month LME aluminium rose $5 to $2,420/$2,425 a
tonne, while Shanghai's active May contract was 220 yuan
higher at 19,590 yuan a tonne.
三个月期铝报于2,377/2,384美元，较周三收盘涨7美元。
沪铝最活跃的5月合约涨160元至19,040元。
三个月期锌目前持平报于2355美元。
