Ann: STRONG ZINC RECOVERY IMPROVEMENT, RECORD METAL PRODUCTION, page-6

NCZ concentrate is moderate grade, reasonable for blending with a penalty or two. It shouldn’t be seen as among the best concentrates available and therefore one would expect the market would price it accordingly.

Albion works but it’s serious new capex even without the need for additional fine grinding. Combination of the shift in zinc price and T&C, piss poor start up and over bullish on stage 1 numbers imo are the main cause behind the current price.
