Hellyer Residues Project Approval Received

Intec Ltd (ASX code: INL) is pleased to announce that the Development Approval has been granted for the Hellyer Residues Project, ahead of the expected schedule.

After receiving a positive assessment and required approval conditions from the Tasmanian Department of Tourism, Arts and the Environment, Waratah-Wynyard Council has today promptly issued the Development Approval for the Project. Intec is now assessing the conditions of the approval.

The Company now intends to obtain the requisite Building Permit in order to commence site works at Hellyer forthwith. This is in preparation for the stockpiling of electric arc furnace dust feedstock, to be transported from the Australian mainland onto the Hellyer site from January 2008. Further engineering work will continue to be conducted for the major plant infrastructure during the March 2008 quarter, with the intention of finalising project finance and/or project partners during the ensuing quarter. Several companies have already expressed interest in becoming involved in the Project.

The receipt ahead of schedule of the Development Approval for the Hellyer Residues Project represents the achievement of another major milestone for the Project, which remains on-schedule for construction in 2008 and operation in 2009.

Yours faithfully, Intec Ltd

Background Notes

The Intec Hellyer Mill, the Hellyer tailings resource and the associated assets are 100% owned by Intec Ltd. The Mill was restarted as the Hellyer Zinc Concentrate Project in December 2006 in joint venture with Polymetals, one of Australia’s largest unlisted mining groups. Under the terms of this 50/50 joint venture agreement, Polymetals will operate the Intec Hellyer Mill for four years (expiring 1 December 2010) or until 6 million tonnes of tailings have been processed, whichever comes first. At the end of the agreement, Intec has the right to purchase Polymetals’ half share for A$1.

Intec Hellyer Metals Pty Ltd is also in the process of implementing at Hellyer the first commercial project utilising the Intec Process, a patented Australian hydrometallurgical technology for the recovery of base and precious metals from a range of different feedstocks. Scheduled for construction in 2008 and operation in 2009, the Hellyer Residues Project to recycle EAF dust (a zinc-bearing waste from steel recycling) will share the Hellyer site, offering a number of synergies between the two operations.
