In order for Chile's El Teniente copper mine to process its daily production of 85,000 tons, 400 liters of water are pumped up to the concentrators at a daily cost of $5,500. To circumvent the expense and unreliability of this water supply, an 11 km tunnel is being driven to the Rio Blanco, which will be tapped at the rate of 1200 liters. This water transmission tunnel is being excavated by the only tunnel boring machine currently at work in South America.
