Johannesburg, South Africa — MININGREVIEW.COM — 15 April 2008 – Metorex Limited – a mid-tier, multi-commodity company listed on the JSE with a secondary listing on the London Stock Exchange – says its Ruashi II hydro-metallurgical plant in the Democratic Republic of Congo (DRC) has started producing copper cathode.

A company news release issued here yesterday confirms that the build-up in copper production levels to the annual plant nameplate capacity of 45 000 tonnes of copper cathode and 3500 tonnes of contained cobalt is expected to take place on a phased basis over a period of about 10 months from 1 April 2008.

During the build-up phase, the solvent extraction and cobalt precipitation modules will be commissioned, and the 500 tpd acid plant is scheduled for commissioning towards the end of 2008.

The Metorex statement explains that the electrical power required to achieve full production will be provided through an upgraded power line from the Karavia sub-station. Work has commenced on this installation, and should be completed during the third quarter of the year. The present power supply from the ZIL sub-station to Ruashi mine enables continuing operations of the Phase I plant, and can provide 50% of the required capacity for the Phase II plant at full production levels.

The Phase I and Phase II plants are being fed largely with ore produced from the open pit mining operation, which has resulted in significantly improved metallurgical recoveries.
