This exploration was located near Norwich. The Boston and Lake Superior was organized in 1846 and had similar mineralization to the Ohio Trap Rock Mine located approx. 0.25 miles away, but was said to not be as rich in copper. Little is known of the exploration or if a mine was even started. The same company also held land in Keweenaw County.
