The gold mining activity in New Hampshire has been variable. It i importnat to mention that the presence of gold in certain rocks of New Hampshire were noted in the 19th century, but was found in small quantities and the extraction was not very interesting. Gold was discovered in the Townships of Franconia and Lisbon, north of Washington peak and on the lower Ammonoosue River as early as 1866. The Eaton lode was discovered in 1826 and yielded lead-silver ore. The Ammonoosue gold field was considered an auriferous slate and schists occurred along the Connecticut River, and lying mostly in New Hampshire.
Up to 1877, a production of gold was reported from the Dodge vein in eastern Lyman. The Lisbon, Cook and Brown mines yield free gold and auriferous mispickel, but were not of much importance as producers of the precious metals. Gold was found in the galena of Gardner’s Mountain, Lyman township, Grafton county and in the Lyman Hills. At a gold mine about 1.5 miles east of Mount Monadnock, several assays of quartz reported gold.
