Large iron ore (magnetite) deposit discovered in 1810. Although the mine is a few miles from Brewster, it is actually in the now defunct hamlet of Tilly Foster, now partly submerged by the Middle Branch Reservoir. The official incorporated name was Tilly Foster Iron Mine. The mine was 600 feet deep in 1879. Mining ceased in 1897, after 13 miners were killed in a rockslide. The articles by Nightingale (2001) provide a historical summary and mineral details, which have been incorporated into the species info pages of this site.
It is famous for its excellent brucite, chondrodite, clinochlore, titanite, and magnetite crystals and antigorite or lizardite (and other species) pseudomorphs after a wide variety of minerals. Dana (1874), Trainer (various), and Nightingale (2001) provide details. This list below is modified from Januzzi (1976):

The Tilly Foster "signature mineral". In 1873 Bridenbaugh described it "as by far the most interesting species found at this locality" (p. 212). E. S. Dana published two detailed papers on the mineral in 1875. In 1938 Trainer described the chondrodite found here as the "finest mineral from Tilly Foster ... The fine crystals are "antiques" for which you pay fancy prices" (p. 297). The deep red crystals found here are unique in their brilliance, clarity, size, perfection, and variety of forms. Various degrees of serpentinization of these crystals are common. It also was abundant in massive form, and in grains within the magnetite ore.
