A former Fe occurrence/mine in goethite (limonite) ore located in the village of Weed Mines, which is mostly in Ancram Township to the south, but the mine is actaully mostly in Copake Township. Owned by Barnum, Richardson & Co. Produced more than 168,000 tons of ore. Workings included a long trench.

This mine, now owned by the Barnum Richardson Company, is located about two miles north of the station of Boston Corner. It has a foot wall of Berkshire schist, which dips eastward very regularly at an angle of about 25°. The ore lay directly upon this foot wall, and has been opened up in a north-south direction for nearly one fourth of a mile. As the foot wall was followed to greater and greater depths it became necessary to drift underground. As usual in the district, the cover consisted of clay and till. No dolomite outcrops near the mine, though there is little doubt that the valley area of the vicinity is in large part underlaid by this rock. The data for the “Weed” mine have been largely obtained from Mr. Theron Moore who was lately manager of the mine. The “Weed” was opened in 1780 and is estimated to have produced 168,000 tons of ore during the succeeding one hundred years. It has been operated until quite recently.
