This was a small mine located in a valley south of Constantine, operating during the 1850s. While its primary focus was tin extraction, it also yielded 6-7 tons of high-grade copper ore. Today, the site is obscured by vegetation. Hamilton Jenkin identified two shafts, which were depicted on the 1879 edition of the 25-inch street map. The positions of these shafts indicate that the mine was exploiting a lode with a roughly northeastward trend.
