In Chile, coal mining is restricted to a few places located in its southern half. Energy originating from coal stands for 11,6% of Chile's electricity consumption.[1] Currently the country is not considered a major producer of coal.[2]
The three zones of mining are Zona Central Sur (36–38° S), Zona Sur[A] (39–42° S) and Zona Austral[B] (51–54° S) in southernmost Chile.[1][3] Most of the coal resources of Chile lie in Zona Austral at southernmost Chile.[4]
| District[3] | Sub-district[3] | Coal-bearing formations | Coal age[5][6] | Sedimentary basin | Coal grade[3][4] | Large-scale mining at present |
|---|---|---|---|---|---|---|
| Zona Central Sur | Sector Norte | Itata Basin | Sub-bituminous | No | ||
| Sector Sur | Curanilahue Formation,[4] Trihueco Formation | Eocene | Arauco Basin | Bituminous | No | |
| Zona Sur | Pupunahue Beds, Mulpún Beds, Cheuquemó Formation, Parga Formation | Eocene or Oligo–Miocene | Pupunahue-Mulpún Neogene Carboniferous Basin, Osorno–Llanquihue Basin | Sub-bituminous | No, mining ceased in the early 2000s | |
| Zona Austral | Loreto Formation | Eocene-Oligocene | Magallanes Basin | Lignitic and Sub-bituminous | No, mining in Invierno ceased in 2020[7][8] |
