Small Cabinet, 8.4 x 7.9 x 3.5 cm
Tilly Foster Mine, Brewster, New York, USA
Ex. Dennis Mullane

This is a significant, and surprisingly attractive, specimen of clinochlore from the old Tilly Foster Mine. According to Large iron ore (magnetite) deposit discovered in 1810. The mine was 600 feet deep in 1879. Mining ceased in 1897, after 13 miners were killed in a rockslide. Specimens today are obviously hard to come by, and I know people who are dedicated to collecting Tilly material. Usually, you get chondrodite, and a few other species like clinochlore as mere associations. However, here it is definitely the dominant species, in a really nice, 3.2 x 2.5 x 0.6 cm, freestanding, crystal. It is easy to see the metallic green color. In fact, I cannot recall a clinochlore of this size, as showy, from any other locale? very OLD classic, Ex. Dennis Mullane Collection
