From certain of the mines, notably the “Ore Hill,” “Amenia,” and “Copake” mines, the so-called “dead-head” or “white horse” has also been mined. This latter material, generally described as iron carbonate, is usually but an impure variety of that mineral, since it generally contains considerable silica and a sericitic or talcose mineral....

The “Amenia” mine, to which is joined the “Gridley” mine upon the north, is located about one half mile southwest from Amenia station. This mine has been operated as recently as 1902. It has been developed principally along the strike of the rocks or about N. 40° E. To facilitate reference to the mine a sketch plan modified from one printed by Putnam is subjoined.

The southeast longitudinal wall of the mine consists largely of schist cut by frequent vertical joints, and exhibits in a striking manner the peculiar “sagging” often observed at iron mines where alteration of the constituents and extensive leaching have gone on. The northeast wall of the pit is formed of much crumpled dolomite, the general dip of which is probably to the eastward. The ore body abutted against this wall which seems to mark the position of a fault. Specimens of fault breccia, the fragments in which are clear vein quartz and the cementing material ore, were picked up upon the dump.
