Invierno mine is a coal mine in Riesco Island, Chile, that was active from 2013 to 2020. The mine exported coal extracted from Loreto Formation to northern Chile and to other countries. The enterprise in charge of the project declared initially the works would occupy an area of 1500 ha representing 0.3% of the area of Riesco Island. Reportedly, it was initially projected to be the first of five coal mines in Riesco Island to be established by Von Appen and Angelini. The development of the mine included both the clearing of Magellanic subpolar forests and the reforestation of areas burned down during the Chilean settlement of Magallanes more than 100 years ago.
