MEXICO CITY, Jul 29, 2011 (Dow Jones Commodities News via Comtex) -- Mexico's mining production rose 24% in May from a year ago, led by a big jump in copper as the Cananea mine in northwestern Mexico ramped up output after reopening last year.

The National Statistics Institute, or Inegi, said Friday that copper production rose 85% from May 2010 to 33,283 metric tons. Silver production was up 23% to 345,917 kilograms, and gold output rose 15% to 7,255 kilograms.

Mining company Grupo Mexico SAB (GMEXICO.MX) reopened the Cananea mine, the country's largest copper mine, last year after a three-year shutdown because of a dispute with the miners union. The company renamed the mine Buenavista.

Zinc production was up 10% from a year earlier at 45,570 tons, and lead output rose 32% to 16,775 tons. Coal production in May was up 59% to 1.5 million tons, and iron production rose 9.9% to 714,656 tons, Inegi reported.
