Bolivia San Cristobal mine says may come to halt

LA PAZ Aug 11 (Reuters) - Bolivia's San Cristobal mine may have to halt operations if protests in the country's Potosi region continue and activists follow through on threats to cut power to the site, a company spokesman said on Wednesday.

San Cristobal, one of the largest mines in Bolivia, produces silver, zinc and lead and is 100 percent owned by Japan's Sumitomo Corp (8053.T: Quote). Its plant that processes concentrates has been shut for two days for maintenance.

"We're very worried. We will evaluate what's been happening to decide if we will resume the plant's operations or not ... if we do not, we could face a complete shutdown of the mine in the short term," San Cristobal spokesman Javier Prado said. (Reporting by Carlos Quiroga; Writing by Hilary Burke)
