Francis Castelnau

Francis Castelnau was a French geologist and naturalist, best known for his exploration of South America in the mid-19th century. His notable discovery of the Mutún hill in 1848 unveiled one of the largest iron and manganese deposits in the world, which has since been a focal point for industrial development in Bolivia. Castelnau's work contributed to the understanding of the region's geological resources, paving the way for future mining and industrial initiatives.
