Canada's Scorpio Mining Corp said production at its flagship Nuestra Señora mine in Mexico rose about 13%, helped by improved mining practises.

Fourth-quarter production at the silver-zinc-copper-lead plant totalled 694 538 silver equivalent ounces, compared with 612 941 silver equivalent ounces a year ago.

The company said it has improved its mining practices to enhance grade control, reduce dilution and increase recovery.

Total plant throughput in the quarter rose 17% to 131 581 t.

The company sees total plant throughput in 2012 to increase by about 2% to 519 000 oz.

Shares of the Vancouver-based company closed at C$2 on Thursday on the Toronto Stock Exchange.
