Strike at San Cristobal silver mine enters fourth day
A four-day-old strike has paralyzed Bolivia's San Cristobal mine, which produces silver, zinc and lead and accounts for about half the country's mining exports, the government said on Monday.
San Cristobal is the world's third-largest producer of silver and the sixth-largest producer of zinc, according to Japan's Sumitomo Corp (8053.T: Quote), which fully owns the mine.
