Aug 13 (Reuters) - Prolonged protests have disrupted output
at two of the world's top silver mines in Bolivia, a major
producer of zinc, silver and lead.

 San Cristobal silver, zinc and lead mine, which is
controlled by Japan's Sumitomo Corp (8053.T), has been forced
to partially halt production, while San Bartolome
silver-operation, owned by U.S.-based Coeur D'Alene (CDE.N) has
been shut due to the unrest. [ID:nN13147146]

 Following are some of the biggest mines and mining groups
in the Andean country, all of which have operations in the
southern Potosi region where the protests are taking place:
