The half year to 31 December 2006 marked Intec's fundamental transition to becoming an operating regional minerals production company, and the only new producer of zinc in Australia in 2006. Intec was pleased to announce on 1 December 2006 the formal commencement of commercial production of bulk zinc concentrate at the Hellyer Zinc Concentrate Project (HZCP, a 50/50 joint venture between Intec and Polymetals (Hellyer) Pty Ltd). This followed a six-month preparatory period, during which the Intec Hellyer Mill and related infrastructure had been refurbished; new equipment had been ordered and installed; all unit operations had been commissioned; and production had been ramped up towards the 'base case' commercial tailings treatment rate of $1.5M$ tpa.

Reference is made to the Review of Operations in the Directors' Report attached to this Appendix 4D.
