The last few months have witnessed a further lift in concentrate supply with more announcements of mines being returned to production. Falling prices in the aftermath of the financial crisis caused large reductions in mined output globally. AME estimates that total zinc in concentrate production for 2009 was 11.3Mt, down from 11.5Mt in 2008. We forecast concentrate supply to increase by 3.8% in 2010 and another 4.9% in 2011. Over the forecast period 2010-2020, we expect concentrate supply to experience a 3.2% CAGR.
