Catamutún is a coal mine and locality in Los Ríos Region, Chile.
The coal bed belongs to either or Cheuquemó Formation or Estratos de Pupunahue.
Mining is facilitated by the lack of any significant fault displacement of the coal beds.
[3] Early mentions of coal near Catamutún include a description by Rodolfo Amando Philippi in 1851 and a passage in Vicente Pérez Rosales' book Recuerdos del pasado in 1855.
[4][5] La Unión, a city with better services and schooling opportunities, became thus a dormitory town for miners.
