re: zinc requirements

OK thanks guys, that clears things up with regards to what the asian benchmark is.

So as far as the "annual" asian benchmark terms go, the way I read this, it is a benchmark set annually, and I guess based on either the average historical or forecasted benchmark, and which is then set for 12 months?

BTW, Current Zinc Offtake is with ZFX picking up the bulk of the zinc at Port Pirie, and with Toho picking up the leftovers. Latest Toho agreement doesn't kick in until 09.
