The Mendenhall Company was formed in 1845 to explore property obtained from the War Department located north of Norwich. Surface improvements and some land clearing took place in 1845 to prepare for mining, which began in 1846. Several shafts were driven on a conglomerate lode and approximately 4,000 pounds of copper was recovered from a sulphur ore that contained copper. All mining ceased in 1849 and the mine was abandoned.
