A later calculation done by some geologist indicates that the reserves could be approximately 25 million tons. The deposit is located in Chile, South America, 12 kilometers in straight line, to the South West of Arauco and approximately 35 kilometers from Curanilahue, Provincia de Arauco, Region of Bio Bio, Chile. The project's logistic is highly attractive. The deposit has a surface area of about 1.000 acres, never mined before. This deposit, which the area authorities have identified as an important and promising developing center of the coal mining activity, is about 80 kilometers from three coal thermo electric power plants.
