Palermo No. 1 Mine (Palermo No. 1 pegmatite), Groton, Grafton Co., New Hampshire, USA

Located near the village of North Groton, on the southeast flank of Bald Mountain. Mined for mica beginning in 1863; later for beryl, feldspar, and quartz. The mine was known as the Hartford Mine until 1888, when it was purchased by the Palermo Mining Company of Schenectady, New York. Since 1973 it has been operated almost solely for mineral specimens, including many rare phosphate species.

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.
