Adventure Consolidated Mine
Introduction
An underground copper mine consisting of three shafts and at least one adit. It is located just south of the town of Greenland, about 15 miles SE of Ontonagon.
History
The Adventure Mining Co. organized in 1850. In 1858 it purchased the Merchants Co. property. In 1870 the company was sold and reorganized under the same name. In 1898, the company was sold again and reorganized under the Adventure Consolidated Copper Co. This consolidation included the Adventure, Hilton, and Knowlton mines. The company suspended all operation in October of 1917.
Production
The mine produced approx. 11 million lbs. of refined copper.
For the Collector
The mine is currently open as a tourist attraction, and tours are given underground during the summer months. Minerals that can be found on the surface piles include copper, silver, and quartz.
