A former Fe occurrence/mine in goethite (limonite) ore located ½ mile SE of Mt Riga station. Originally owned by the Mt Riga Iron & Mining Co., then Barnum, Richardson & Co. Initially closed February, 1885, reopened & closed again in 1888. Workings featured an open pit 500 feet long by 100-200 feet wide.
This mine is located to the west of the main highway about three miles north of Millerton and four miles south of Boston Corner. In the immediate vicinity of the mine no rock is now exposed, though limestone appears some distance to the west. The foot wall was mica slate and had a gentle dip eastward toward the mass of Mt. Washington. The cover of the ore body was, as at so many mines of the district, hardpan, - a mixture of clay with glaciated pebbles, - and till. (See Fig. 16.) According to Putnam a tongue of the hard-pan was found forced under the ore. The mine was operated as an open pit until a depth of 100 to 150 feet was reached. A shaft about ninety feet deep was put down from a point a little east of the margin of the pit. The mine was opened in 1865 and is estimated to have produced a total of about 61,000 tons of ore. It has now been abandoned for more than thirty years.
