Mexico: Mining and metallurgic production dropped 6% in Mexico in the first four months of 2014, the steepest fall for a similar period since 2009, according to the national institute of statistics and geography (INEGI). The drop was attributed to a fall in coal, gold, iron ore, silver, fluorite and lead production. In contrast, gypsum, coque, sulphur, zinc and copper output rose in the same period.
