LIMA, Mar 23, 2010 (Dow Jones Commodities News via Comtex) -- A strike begun Tuesday at a copper mine owned by Doe Run, a unit of the U.S.-based Renco Group Inc., has stopped production, a union official said.
The strike is the second this year at Cobriza, Peru's sixth-largest copper mine, which produced 18,519 metric tons of the red metal in 2009, according to mining ministry figures.
"The strike is indefinite," said Luis Castillo, general secretary of Peru's National Federation of Mining.
Castillo said the strike was called by workers demanding a one-time bonus. The same reason was given for a two-day strike at Cobriza in mid-February.
