Argentine mining company Minera Alumbrera Ltd. said Tuesday its key port along the Parana River isn't able to receive or load copper-gold concentrates due to a strike that has closed neighboring ports used by grain exporters to ship their products to global markets.

"We have a certain amount of storage capacity. We might be a few weeks away from shutting down" the filter plant, Raul Mentz, the company's sustainable development director, told Dow Jones Newswires.

The filter plant separates water from copper-gold concentrate that is transported to a railroad depot from the mine by a slurry pipeline. The concentrate is then shipped to the port by rail.

Mentz estimated the company can continue to operate the filter plant for about two weeks, after which time concentrate will have to be stored near the mine.

Alumbrera has storage capacity for 60,000 tons of concentrate at its port and about 40,000 tons at other locations, including its mill, rail cars and filtering plant, he said, adding that it's too early to say how much of its storage capacity outside of the port is available.

The open pit mine, Bajo de la Alumbrera, has annual production capacity of 150,000 metric tons of copper and 400,000 ounces of gold in concentrate, according to the website of the mine's biggest shareholder, Xstrata PLC (XTA.LN). The mine also has capacity to produce about 1,600 tons of molybdenum concentrate a year, which is trucked to Chile for processing.

Minera Alumbrera is operated by a subsidiary of global mining giant Xstrata, which owns 50% of the company. Canada's Goldcorp Inc. (GG) and Yamana Gold Inc. (AUY) own 37.5% and 12.5%, respectively.

Alumbrera has become the latest casualty in a labor conflict that started last Wednesday, when unions affiliated with a chapter of Argentina's powerful labor-umbrella group, the Confederacion General de Trabajo, or CGT, blocked access to port terminals near the city of San Lorenzo to demand a higher minimum wage.

The CGT unions represent people indirectly linked to the ports and related oilseed crushing plants who work in activities ranging from trucking to food service.

Mentz said Alumbrera's employees aren't involved in the strike.

Alumbrera shares a common main entrance with five other ports. With the main gate blocked by picketing union workers, Mentz said Alumbrera's employees can't get to the company's port, nor can copper-gold concentrates be brought in by rail.

Alumbrera Tuesday asked the Labor Ministry to intervene in the labor dispute at San Lorenzo, Mentz said, adding that its next ship is scheduled to dock in late February.

Located at 2,600 meters above sea level in Argentina's Andean province of Catamarca, Alumbrera started operations in 1997.

Concentrate is pumped through a 316-kilometer slurry pipeline to Cruz del Norte, Tucuman province, where it's then carried about 1,000 kilometers by rail to be loaded onto ships bound for international markets. The port can handle Panamax-size vessels, according to Minera Alumbrera's website.

Copper prices hit fresh records Tuesday, thanks to the continuing recovery in global manufacturing. The most actively traded copper contract, for March delivery, jumped 8.85 cents, or 2%, to settle at $4.5470 a pound on the Comex division of the New York Mercantile Exchange.

Copper traded on the London Metal Exchange also closed at a record $9,945 a metric ton, roughly equivalent with New York prices, and later traded even higher.

The already optimistic outlook for world copper demand was further bolstered by several indicators. U.S. manufacturing activity in January rose to its highest level since May 2004, Chinese purchasing managers' indexes registered growth and euro-zone manufacturing jumped to a nine-month high.

The pickets in the San Lorenzo area have affected at least 10 ports and crushing plants belonging to major grain and edible oil exporters like Bunge Ltd .(BG) and Cargill.

Alberto Rodriguez, president of the industry trade group representing Argentina's edible-oil makers and grain exporters, CIARA-CEC, said Tuesday the strike has delayed 46 ships, forcing some of them to moor well downstream.

About three-quarters of Argentina's agriculture exports are shipped from river ports clustered around the city of Rosario. Argentina leads the world in soymeal and soyoil exports and is the third-largest soybean exporter.

San Lorenzo, located about 12 miles north of Rosario, is home to a dozen ports that handle wheat, corn, soy, soymeal, soyoil and related products.
