The unsettled southern regions of Chiloe (mainland) and Magallanes are traversed by a number of important rivers which have been only partially explored.
Horse and mule breeding are carried on to a limited extent, and since the opening of the far South more attention has been given to sheep. Goats and swine are raised in small numbers on the large estates, but in Chiloe swine-raising is one of the chief occupations of the people.

Gold is found in nearly all the provinces from Antofagasta to Concepcion, and in Llanquihue, Chiloe and Magallanes territory, but the output is not large.
The island of Chiloe, which lies immediately south of the province of Llanquihue, is a continuation of the western Chilean formation, the coast range appearing in the mountainous range of western Chiloe and the islands extending south along the coast.
