8 In May 2009, the Suralco alumina refinery announced curtailment of 870,000 mtpy. The decision was made to protect
the long-term viability of the industry in Suriname. The curtailment was aimed at deferring further bauxite extraction
until additional in-country bauxite resources are developed and market conditions for alumina improve. The refinery
currently has approximately 893,000 mtpy of idle capacity.
9 Reductions in production at Point Comfort resulted mostly from the effects of curtailments initiated in late 2008 through
early 2009, as a result of overall market conditions. The reductions included curtailments of approximately 1,500,000
mtpy. Of that original amount, 384,000 mtpy remain curtailed.
