UPDATE 2-Operations at Peru's Buenaventura halted on strike

* Workers want a larger slice of profits

* Company says no possibility of talks (Adds details on demands, government involvement, byline)

LIMA, Feb 15 (Reuters) - A workers' strike has halted production at two gold mines and a silver mine owned by Peru's largest precious metals miner, Buenaventura BUEv.LMBVN.N, company and government officials said on Monday.

Workers, who have been on strike since Saturday, are demanding the company pay them a portion of its profits, Milagros del Rio, the national director of labor relations at the Labor Ministry, told Reuters.

She said miners also want the company to show them information related to the state of Buenaventura’s finances between 2006 and 2009.

Peruvian law requires mining companies share 8 percent of their profits with workers.

The strike has stopped production at the Orcopampa and Antapite gold mines and the Uchucchacua silver mine, Carlos Galvez, Buenaventura’s chief financial officer, told Reuters.

“There’s no possibility of talks. There’s nothing we can do. We’re letting time run out,” said Galvez.

He said Buenaventura has until the end of March to report its earnings to the state, at which point the value of workers’ profits will be determined.

The Labor Ministry has declared the strike illegal -- a decision the union has appealed.

A ruling on the appeal is expected as early as Tuesday, the ministry said, and if the initial decision is upheld, the company could begin to fire striking workers.

Besides the mines it operates directly, Buenaventura holds minority stakes in Yanacocha -- one of Latin America's largest gold mines -- and Cerro Verde CVE.LM, a major copper pit.

Globally, Peru ranks No. 1 in silver production and sixth in gold. (Reporting by Marco Aquino; Writing by Dana Ford; Editing by Gerald E. McCormick)
