After a lovely, though short, walk in the woods of the fall forest of robles (oaks), we headed off for lunch up in the Parque Ingles, which despite its name is actually a reserve. Reserves have less protection than parks here and it is hoped that this reserve may become a park this year in commemoration of an anniversary for parks.

The mining company owned by the Republic of Chile, Codelco, operates the mine. El Teniente is one of their biggest operations and includes an underground mine, a concentrator plant, and a smelter. Our tour focused on the underground mine. The mine has more than 2,800 km of tunnels and galleries. About 130,000 tons of ore is extracted from the mine daily, with a yield of about 13 kg of copper per ton.
future generations to enjoy. Leaving the quartz cavern the team rode the elevator to the next level to see the underground train system used to collect ore from different mining areas. The grande finale to the underground tour was a for the team to take a ride on the ore train out of the mine to the ghost town of Sewell. Sewell was the original mining town where Chilean and North American miners lived. The miners were relocated from Sewell to Rancagua in the 1970s. Codelco is in the process of restoring Sewell for tourists and will be the largest open air museum when complete.
