Information Release: 31 July 2007 Smorgon and Intec Sign Stage 2 EAF Dust Agreement

Smorgon Steel Group Ltd (ASX code: SSX) and Intec Ltd (ASX code: INL) yesterday entered into the Stage 2 EAF Dust Supply and Treatment Agreement for the ongoing supply by SSX over a (minimum and renewable) three year period of electric arc furnace dust (EAF Dust) as feedstock for INL’s Hellyer Residues Project (HRP) in northwestern Tasmania. The HRP is expected to commence commercial production in early 2009.

This Stage 2 Agreement builds upon the Stage 1 EAF Dust Stockpile Transfer and Treatment Agreement between SSX and INL dated 21 February 2006 in relation to the 20,500 tonnes EAF Dust stockpile in West Footscray, Melbourne (also to be treated via the HRP). It also follows the successful extraction during 2006 at INL’s demonstration plant in Burnie, Tasmania of effectively all of the contained zinc, lead and silver from SSX’s ‘arising’, and INL’s stockpiled, EAF Dust.

The state regulatory authorities in Victoria and Tasmania have given the relevant approvals for the interim storage of the EAF Dust under the Stage 2 Agreement and for the renewed operation of the Burnie plant on a feedstock primarily consisting of EAF Dust, which is expected to commence on a campaign basis late in the current quarter, in order to provide detailed operational and engineering data for the HRP.

SSX will supply INL with all of its approximately 15,000 tonnes (minimum 14,000 tonnes) of EAF Dust production per annum, with zinc grades expected to exceed 30% from the outset. Additionally, current efforts at SSX’s Laverton, Victoria and Waratah, NSW mills are expected to continue gradually to increase the zinc grade contained in their EAF Dust product over time. Deliveries of EAF Dust to Intec from SSX’s Waratah and Laverton mills commence today and tomorrow respectively.

Philip Wood, Managing Director and Chief Executive Officer of INL, stated “The ongoing supply of EAF Dust by Smorgon Steel, Australia’s largest producer, contains about A$20 million per annum worth of recoverable zinc, lead and silver at today’s prices. Last year’s Burnie demonstration plant program showed that the Intec Process enables virtually all of the contained metals to report to saleable product, within the existing business operations of the Hellyer Zinc Concentrate Project. Securing this ongoing feedstock from Smorgon (with others to follow) on mutually favourable economic terms for our Hellyer Residues Project represents a significant milestone in the commercial-scale application of the Intec Process.”
