TOKYO - JFE Steel Corporation (President: Hajime Bada), Mitsui & Co., Ltd. ("Mitsui"; President: Shoei Utsuda) and Erdos Electric Power & Metallurgical Co., Ltd. ("Erdos"; President: Linxiang Wang) have reached agreement to expand the silico-manganese plant operated by the three companies as a joint venture at Inner Mongolia EJM Manganese Alloys Co., Ltd. ("Erdos EJM"). After receiving the necessary licenses and permits from the Chinese authorities, the partners plan to increase the company's capitalization from 15 million US dollars to approximately 30 million US dollars by the end of the year.

Expansion will entail construction of a second plant (No. 2 plant) that will be of the same capacity as the No. 1 plant that came online in July 2006 (25,500 kVA x 2 units; 75,000 tons/year); commercial production is expected to commence at the end of 2008. When the No. 2 plant comes online, Erdos EJM will have a total silico-manganese production capacity of 150,000 tons/year, making it the largest producer in China and one of the largest producers anywhere in the world.

The JFE Steel group purchases approximately 90,000 tons of silico-manganese a year, employing it as a manganese additive and de-oxidant in steelmaking. The vast majority is imported from Erdos EJM. However, the rapid growth of the Chinese steel industry in recent years has resulted in a sharp increase in demand for silico-manganese in the domestic Chinese market, making it more challenging to secure stable supplies of the material. The addition of the No. 2 plant will give the JFE Steel group a more stable silico-manganese sourcing system.

Mitsui supplies manganese ferroalloy, primarily to Japanese firms. Its investment in the construction of the No. 2 plant at Erdos EJM will strengthen its framework for a stable supply of silico-manganese to the JFE Steel group and other customers.

Erdos, working under the Chinese central government's policy to develop the western regions of the country, is implementing a ferroalloy production project using thermoelectric power generated with the abundant coal resources in the city of Erdos, Inner Mongolia Autonomous Region. The addition of the Erdos EJM No. 2 plant alongside the No. 1 plant and the ferrosilicon and silicon carbide plants will further expand the company's ferroalloy production system.
