LUSAKA, Zambia, Feb 24, 2012 (Dow Jones) -- Management and labor unions at Zambia's Chibuluma copper mine said Friday they have agreed to resume wage negotiations Monday, after three days of stoppage by 600 unionized employees that affected production at one of Zambia's oldest mines.

Operations at Chibuluma, a subsidiary of China's Jinchuan Group (2362.HK), were halted last week following disagreements over a revision to shift lengths as a precondition for a 14% wage increase.

Chibuluma General Manager Jan Trouw told Dow Jones Newswires that the strike had ended and production was back to normal. He declined to elaborate on workers' calls for his removal or the effects of the strike on the company's productivity.

Chibuluma mine produces an estimated 50,000 metric tons of copper a year, according to the company's website.

"We are meeting the union on Monday for talks," Trouw said.

This was confirmed by Mine Workers Union of Zambia President Charles Mukuka, who said the situation at the mine has "normalized," and that the union is trying to secure the release from police custody of seven miners arrested for damage to property.
