Copperwood mine
The Copperwood Mine is a development-stage project located in Ironwood and Wakefield townships, Gogebic County.
Exploration of the area led to the discovery of the Copperwood deposit in the 1950’s, which is a sediment-hosted stratiform copper deposit hosted in the Nonesuch Formation within the Presque Isle Syncline, with fine-grained chalcocite as the copper bearing mineral. Highland Copper Company owns the project and currently holds several permits required by EGLE to conduct mining and associated activities, including a Mining Permit. Their mine plan includes underground mining methods with an anticipated life of mine of about 14 years. Construction has not commenced.
