The Hays Mine, located at Fort Wilkins State Park (there are also pits on Hays Point), was started in 1844 after soldiers building the Fort ran across large rocks that contained a black copper oxide. Miners from the Hays Point operations were sent to explore the area and discovered the continuation of the black copper oxide veins discovered at Hays Point. In 1845, two shafts were drilled and yielded about 40 tons of ore. Later in the year a third shaft was sunk down to a depth of 120 feet. Exploration work tracked the vein across the lake and an adit was drilled into the side of the hill. During this time, the mine owner (The Pittsburg and Boston Company) began work on another mine south on the Peninsula that would become the first profitable copper mine on the Keweenaw, the Cliff Mine. All three shafts can be seen today; however, because they are on State Park property, no collecting is allowed.
