Beginning in 1803, Boston businessman Sam Ruggles started digging in the hills of Grafton, New Hampshire for the flaky mineral called mica. For about a century and a half, Ruggles Mine grew into a successful commercial mining operation, then later a popular New Hampshire tourist attraction. The mine, however, closed down in 2016 and has been dormant since. But hope is not lost! In 2024, Ruggles Mine in Grafton will be reopening to the public under new ownership.

Ruggles Mine in Grafton opened as a public tourist destination in 1963. In its commercial heyday, mica was mined here for use in everything from cosmetics to toasters.

In its tourist era, the mine was a destination for rockhounds, who could keep any of the various minerals found on the ground or which could be chipped loose with tools.
