An iron mine located at Benson near Fine. The ore is low-grade magnetite hosted in banded, garnetiferous, pyritic gneiss. 1,500 feet long, 200 feet wide and 20 to 50 feet deep (1937). In the 1950s, the mine was considered the largest open pit iron-ore mine in the world. It was finally closed in 1978.
