Located near the village of North Groton, on the southeast flank of Bald Mountain. Mined for mica beginning in 1863, though not on a serious level until the Hartford Mining company worked it from 1878 to 1888. Later it was a source of beryl, feldspar, and quartz, too. The mine first became known as the Palermo Mine in 1888 when it was purchased by the Palermo Mining Company of Schenectady, New York. When General Electric owned and operated it from 1898 to 1945 it was known as the GE Mine, which produced muscovite, microcline and beryl. The name reverted to Palermo Mine when the Ashley Mining Corp. leased it from GE from 1945 to 1958 and since then that name has remained. It was owned by the Mountain Mining Company until 1973 and leased to N. E. Materials (Rex Howard, who mined the quartz core) and later Peter Samuelson. Since 1973 it has been owned by the Palermo Mining Co. LTD and operated almost solely for mineral specimens, including many rare phosphate species. (Whitmore and Lawrence, 2004).

Fuller (1898) reported on a pocket at the mine which was said to be ten feet in diameter. A quartz crystal, three feet in diameter, was taken from the roof of the pocket, according to the mine superintendent at the time.
